Military Collections in Sweden – Fourth Chapter

The geographical location of Sweden on the map of Europe naturally put it on the front line of the Cold War. With a very long shoreline taking most of the northern border of the narrow waters of the Baltic Sea, since jets made their appearance on the stage of military strategy, this Scandinavian kingdom found itself just minutes away from the Soviet Union (which at that time engulfed also today’s Estonia, Latvia and Lithuania), as well as from Communist-led Poland (see for instance this post) and German Democratic Republic (much covered on this website, see for example here).

Keeping up with a long-established tradition of neutrality, dating from soon after the age of the Napoleonic Wars in the early 19th century, during WWII and, afterwards, with the beginning of the Cold War, Sweden managed to stay out of any major explicit alliance with the Western Nations. During the Cold War, by continuing this non-aggressive policy, Sweden was a relevant contributor to the overall stability in the Northern European region.

Considering the early accession of Norway and Denmark to NATO to the West of this sector, in the momentous years following WWII when the USSR was still ruled by Stalin, who had just aggressively sealed the fate of the newly-conquered dominions in Eastern Europe, the independence of Finland, sharing a long, militarily untenable land border to the East with the Soviet Union, was particularly precarious (see Hanko, in this chapter). While leaning towards the West and being historically adverse to Russia, Sweden carefully avoided entering NATO, while still establishing commercial links notably with the UK and France for military supply. This attitude, and the increased geographical distance between NATO and the USSR, likely helped to dilute tension between the two opposing blocs in the area – which nonetheless peaked at some points in history before the demise of the USSR – thus mitigating the chance of an outbreak of hostilities, despite a massive military presence on both sides.

Concerning the military budget however, the neutral policy of Sweden did not by any means entail renouncing to self-defense. A solid economy with natural resources and a well-established tradition in mechanical industry and warfare supply, Sweden was perfectly conscious of the need to sustain its geopolitical role with a credible military power, such to deter as much as possible an aggressor, and ensure survival in case of an open war, even in the high-technology war scenario developing in the post-WWII years. Spared the devastation brought about by WWII, Sweden’s strategy planners and industry started in earnest developing especially ground and air forces.

The development of the air force and the air defense system was carried out in an integrated fashion, within the STRIL (Stridsledning och Luftbevakning, which might be translated into Combat control and Air surveillance) programs. Updated over the years (notably the first being the embryonic STRIL 40, followed by -50, -60 and -80, corresponding roughly to those decades in the 20th century), this program embodied the need for monitoring and self-defense. Considering in particular threats coming from the air, airspace monitoring and related information gathering/processing were carried out through a purpose-designed network of stations and command centers. Having ascertained the type of threat, the Air Force would deploy a proportional countermeasure, accounting for its plans for self-defense. This could be carrying out an intercept by scrambling aircraft – something which happened regularly for the decades of the Cold War, following violations by the Warsaw Pact forces – or, in case of an open aggression, for example deploying SAMs to down attacking aircraft.

The evolution of the STRIL program over the years reflects the development in the technology of the threats, and of the defense system itself. This passed from being based on optical detection and early jets, brought to an intercept point with purely verbal communication, to several types of radars linked directly to situation rooms, and purpose designed aircraft, which starting from the SAAB J35 Draken in the 1960s could receive data of an aggressor via datalink.

After the end of the Cold War and the collapse of the USSR, changes in the geopolitical scenario meant the partial scale-down of the Armed Forces, yet also the update of the still existing Sweden’s surveillance system based on more modern technology. Notably, Russian scouting operations and temporary violations of the air space of Sweden have continued over the years, thus giving a practical reason for maintaining a minimum level of alert.

As shown in previous chapters on this site (see here, here and here), retracing the fascinating history of the Armed Forces of Sweden through visits to dedicated museums, collections and surviving sites, especially the Cold War decades did leave behind some traces, which are still there to be seen.

In this chapter, two sites with many links to the history of STRIL can be found. One is a perfectly preserved installation, a node in the airspace monitoring network in Åstorp, close to Helsingborg. The other is the exceptional technical collection of the Missile Museum in Arboga, run by former staff of the Armed Forces of Sweden and passionate technicians, and preserving in a lively and rich exhibition countless items retracing the history of military missiles, as well as many aspects of air defense, especially in Sweden over the Cold War years.

Photographs have been taken from both sites during visits in the summer of 2025.

STRIL Sector Operation Center (SOC), Åstorp

On the origin of the STRIL system – Brief historical note

The STRIL system, an acronym standing for Stridsledning och Luftbevakning, which might be translated into Combat control and Air surveillance, was first systematized in 1948, following the preliminary program STRIL 40, with its roots in the experience gained and in the technology of WWII. A key component of it was the availability of air surveillance stations, physically built as soft manned tower constructions, where staff of the Optical Air Guard, typically voluntary women, kept the airspace under watch (similar to the Royal Observation Corps in Britain, see this chapter). Before 1948, information from these visual intelligence gathering points traveled to a number of decision centers (Jaktcentral, precursors of the Sector Operation Centers) by wire, where additional staff of the Guard managed to create an overall picture of the situation and threats, and military officers could eventually authorize a reaction, typically scrambling aircraft for an intercept, in case of an airspace violation.

With the quick and dramatic evolution of military technology in the first years of the Cold War, the STRIL 50 system, started in 1948 and fully implemented by the mid-1950s, inherited, developed and structured the existing network. The territory of Sweden was divided in 21 sectors, which were covered by optical information gathering points, in the form of 1’300 Air Surveillance Stations (Luftbevakningsstation, or LS in short), i.e. towers like in the previous system, manned by the same Optical Air Guard, which however was now under the control of the Air Force. Arranged in a hub-and-spokes fashion, these stations reported to Sector Operation Centers (or SOC, Luftförsvars Gruppcentral, or LGC), of which 50 existed over the national territory. Finally, the command and control (C2) centers were 11 so-called Air Operation Centers (Luftförsvarscentral, or LFC), where the military staff could authorize and coordinate a counteraction against a threat.

Radar systems, both range-finding and altitude-finding, were a major technological addition of STRIL 50. Initially imported in the form of light or movable systems with moderate capacity, a constant investment in this technology brought to Sweden premium British (Marconi, Decca), Italian (Selenia) and later US (ITT-Gilfillan) technology. Radar information was a mainstay of the STRIL 60 program, largely integrating usual optical LS towers, thus strongly increasing the coverage and range of the pre-existing monitoring system. The level of automation increased steadily over the 1960s and 1970s, merging range, altitude, speed and direction information of a potential threat, and presenting them on a digital plotter to human controllers, directly in the LFC C2 centers. At the beginning of the 1960s, datalink parameter transmission allowed controllers in the LFC to provide flight data of an aggressor to the cockpit of the J35 Draken, avoiding easily detectable verbal communication, for an increased level of effectiveness.

In this constantly evolving technological scenario, the implementation of the OPUS system allowed to still profit from the pre-existing LS and local LGC centers. Within that system, the human operators where supplied with a threat labeling system, allowing them to digitally communicate data of whatever optically detected air traffic, including position and direction. This was automatically collected and filtered in purpose-implemented electronics within the LGC, visualized on a local plot, and forwarded after filtering to the LFC, thus integrating the automatically-processed radar information available to the C2 centers. Perceived also as a safety layer in case of an attack to the inherently vulnerable radar stations, the Optical Air Guard stayed until after the end of the USSR, finally disbanding in 1994.

A visit of the site

What you see in Åstorp is an original, perfectly preserved Sector Operation Center, i.e. an LGC, which stands as an ideal specimen to understand the structure and technology of this element in the defense network implemented through STRIL.

The Center is in a bunker built underground in the rock (as typical to the early Cold War era, see this chapter), and is accessible via a steep and narrow flight of stairs from an unassuming, deceptive wooden hut. Once to the bottom, the structure is all at the same floor level.

A technical room is accessible besides the entrance, with a power generator and electric cabinets for managing power supply in the bunker. The major components in the system, still working, are made by Hägglunds, a major mechanical brand in Sweden (also making the highly successful Bandvagn 206 tracked trailer vehicle, still in use today).

Then you get access to the main hall of the bunker, with a somewhat informal appearance, dominated by armchairs and low tables, and with a kitchenette in a corner. Everything is original and clearly dating from the Cold War era in terms of style.

From this gathering and relaxation point in the bunker, it is possible to reach immediately four relevant functional rooms. The first, and likely the most distinctive, is the situation room, which is visible also from the hall through a large transparent glass window.

To the far end from the entrance is an elevated console desk, with signal receivers, telephones and keyboards.

The room is basically built around a tactical table, with a map of the area pertaining to the SOC, where the information gathered by the LS reporting to this station could be represented graphically. The table you see is possibly the only reconstructed part of the bunker. Over the years, with the technological developments described above taking place (especially in STRIL 60), this table was updated with some degree of automation in the representation of information. The original piece in place when the bunker was decommissioned was taken away at some point, and a careful reconstruction of an analog table has been employed to give a lively idea of the appearance of the situation room in a time when information was managed manually. Furthermore, a regional map and a situation board are visible close to the entrance.

The location was manned by staff of the Optical Air Guard, traditionally women since the WWII era. These were regimented non-military voluntary staff, whereas the commanding officer of the center was from the military. He usually stayed in a second room reachable from the bunker hall, and overseeing the situation room through a smaller glass window.

In that room, his desk has been preserved in a mint condition, with a typewriter, and even military kits with pens and pencils. Close by is a more recent computer console, with a cryptography device.

A very interesting component of the visit is a number of original manuals and publications scattered around the bunker. Among them are aircraft recognition manuals, reporting the silhouette of known aircraft from all nations, and the corresponding relevant performance. These original manuals offer an interesting cutaway of the air force arsenals on both sides of the Iron Curtain, and their evolution over the years.

Another core technical room reachable from the hall is dedicated to signal gathering and management. The appearance here is mostly from the higher-technology phases of STRIL 60 and the OPUS system. Among the most distinctive features are the cabinets with the electronic boards from the era, which allowed for the management of the data coming from the peripheral station of the network, including for filtering, visualization on the situation table, and forwarding to the LFC.

The original devices once employed by staff on top of the LS towers are on display here – two portable consoles, one for vocal communication, and another special console for allowing the controller to specify data of the observation target, including its course. The original battery pack is still in place, with labeling from the time.

Interestingly, some of the older optical gear is actually from Hitler’s Germany, marked with the Eagle of the Third Reich.

Vocal communication lines allowed inbound traffic, as well as broadcasting capability, which could be directed also to the local population in case of an incoming attack, also employing recorded messages.

The fourth technical room accessible from the hall is was for air pumping and filtering. Despite not intended for survival of a numerous staff over a long time span, the bunker had an air filtering capability, as typical from the WWII and early Cold War era, when the bunker was built. Today, this system helps in keeping the place ventilated and fighting humidity. Manual pumps from the time are in place, as well as original spare parts, from governmental supply.

Finally, a small sleeping room, reportedly seldom employed for the task, can be found with original berths.

Getting there and visiting

The site is not open to the public, and credit for allowing me and a friend of mine on this exceptional visit goes to the current manager of the place, Mr. Anders Sundberg, and to Mr. Erik Mårtensson, retired officer of the Armed Forces of Sweden, who arranged this visit. It is possible to visit the place by prior appointment only. Contact sightraider.com to establish contact with Mr. Sundberg, who speaks English and has a detailed knowledge of this site as well as of the entire defense system of Sweden since its origin. A visit is therefore warmly recommended for a first-hand experience of an original site within the defense network, and for learning about it from its knowledgeable manager.

Missile Museum, Arboga

The Arboga Robotmuseum, mostly dedicated to missiles, engines and air defense systems of Sweden, can be found in the town of Arboga, roughly 90 miles west of Stockholm.

The town has a long tradition in warfare development, an heritage which is still lively represented by the presence of the Armed Forces and of companies operating in the field of intelligence and warfare systems, including a branch of SAAB. Their quarters are to the south of the town, where an old airbase can be found, with a one-of-a-kind bunker in the side of a local hill, dating from the 1940s. Today employed as a warehouse and barely visible from the northern fence of the airport, this bunker-hangar was designed for missile-related study and development, witnessing a significant commitment of the Swedish government towards that field of research, and towards the town Arboga as a strategic location, already back in a time when rocketry was in its infancy.

The museum is geographically close to the city center. Besides being supported by the Government within the official network of museums dedicated to the heritage of the Armed Forces in Sweden, it is run by a dedicated group of enthusiasts, mostly former military staff or knowledgeable technicians, which give an especially lively atmosphere to the place.

The display starts with a collection of items retracing the history of rocketry in Sweden. Curiously enough, a rare original V-1 from Hitler’s Germany dominates the display by the entrance! Similar to other locations in northern Poland and the Danish island of Bornholm (see here), territories geographically north of the Third Reich’s experimental laboratory of Peenemunde (see this chapter), and within range of the V-1 and V-2 early self-piloted flying weapons, were crash-landing places for experimental flights gone out of control. Southern Sweden was no exception. Moreover, the one you can see in Arboga is the only well-preserved V-1 landed in Sweden. The good state of conservation is evident looking at the fuselage and engine casing.

Even the onboard systems are almost perfectly in shape, including the knob to set the target distance covered by the flying bomb (measured approximately, by recording the rotations of the small ram propeller to the front). Also the actuators for the movable tail surfaces can be seen. They were fed from two tanks of compressed air, one of them, sectioned, revealing the fabric-inspired construction.

Most interestingly, the pulse-jet core, with the injection pipes and the radially oriented valve system, is also displayed.

For many nations including Sweden, the analysis of the – for the time – very advanced aeronautical projects of the Third Reich constituted a valuable starting point for their own development programs in the field. The topic is relevant to the museum in Arboga, where many early designs of autonomous flying platforms developed in Sweden are represented. Notably, an early project from the Navy, the RB310 on display, from soon after WWII, was pushed by the the same motor type as the German V-1 (note the distinctive side inlets).

Yet until the late 1950s the pulse-jet concept lived on with the RB315 ‘Agaton’, where the air breathing component of a developed version of a pulse-jet (the SM11, not dissimilar at a glance from the original German design) can be seen emerging on the fuselage.

Still air-breathing yet based on small turbojets, two interesting designs from the same era are on display. One is the compact long-range anti-shipping RB15F, developed for the SAAB AJ37 Viggen, and employed as well with the JAS39 Gripen. The other is the target drone developed by Beechcraft in the US as MQM-107, and in service in Sweden as the RB06. Its own small French-made TRI 60 turbojet can be seen below the the aircraft.

Perhaps the most massive among those on display is the ship-mounted version of the RB08A. This design was operationally employed within the Navy (see here), and later for coastal defense employing land-based batteries. It was pushed by a small turbojet by the French company Turbomeca. This heavy radar-homing anti-shipping missile is displayed with some of its 1960s-fashion internal systems dismounted.

A full array of missiles employed by Sweden’s Armed Forces yet originally designed in NATO Countries is on display, along with a number of prototypes and models originally from Sweden.

A less-known chapter well covered here is that of special under-wing pods. For example, the BOY401 flare dispenser for the Gripen reveals a massive sized and non-trivial construction, when checked from a close distance. Even more complex is the BOX3 pod, originally designed in the 1960s for the SAAB J32 Lansen as a decoy dispenser for detection jamming, with provision for flare and even a nose-mounted radar.

Active jammers are represented for example by the Apparat 27 and the U22 capsule, on display side by side, ahead of the fuselage piece and engine from a SAAB J37 Viggen.

A second area of the museum is dedicated to diverse smaller-scale ground-launcher missiles, as well as drones. For example, the very successful RB53 Bantam and RB56 ground-launched anti-tank missiles are on display, with the corresponding aiming device and computer. The bigger RBS17, the Swedish version of the AGM-114 Hellfire, has been placed side by side with others, allowing for a direct size comparison. It is in service with the coastal defense artillery.

An interesting cutaway is offered for the case of the RBS90 surface-to-air missile, revealing the complexity within the casing of this type of weapon. Nearby are two unmanned flying platforms employed by Sweden’s Armed Forces, the French-imported UAV01 and the lighter Swedish design of the UAV02 with its own control console. Sweden employed a SAM systems for protection of strategic sites, like airbases. Notably, the massive British-design Bloodhound missile was employed (one can be seen outside the museum). A detailed scale reproduction of a a SAM battery cand be found here as well.

Cameras, flash lights, pods employed for PHOTINT/SIGINT, and a radar head from the nose cone of a J37 Viggen attack aircraft are on display as well.

Notably, some of the gentlemen behind this collection were deeply involved in the airspace monitoring and defense activities of Sweden (see also the previous site on this page) during their military careers. Their experience with the STRIL initiatives is a fundamental knowledge base in this respect, and a chat with them is warmly suggested for everybody with an interest in this chapter of warfare history. Some of the radar consoles to be found in the top-level nodes of the air defense network (LFC), where all data from peripheral nodes were assembled to represent the detailed situation of the air space, are on display in the collection. They allow the visitor to retrace the technical evolution of the radar technology for air defence.

Notably, since the arrival of the SAAB J35 Draken, it was possible to send the data of an intruder to the panel of the aircraft via datalink from the console of the radar system (in particular the Decca PS-08 radar, of which four covered the exposed territory of Sweden, was an enabler in getting sufficiently accurate data). The console is on display together with the panel of the Draken. A supersonic single-pilot aircraft with exceptional performance, that aircraft was not easy to pilot with a fully analog cockpit. The addition of information on another aircraft, theoretically very effective for managing an intercept, in an operative scenario required a very high skill and preparation by the pilot, to face a very high workload.

The general amelioration of electronics over the years allowed to develop these systems, in conjunction with the appearance on the scene of the SAAB J37 Viggen and later the JAS39 Gripen, greatly reducing the workload of the pilot by displaying target information on scopes or maps, making them more promptly usable.

A mainstay of the defense system, radar consoles allowed controllers to keep the entire airspace of Sweden under watch. During the Cold War, the range of these systems allowed to scan well south of Berlin and within the USSR. However, the vantage geographical position of Sweden on the boundary of the Eastern Bloc put this Nation at risk of intrusion. For safety, in the mutual mistrust among opponents typical to the Cold War, camera recorders were employed since the 1960s to keep trace of radar blips, also to the aim of proofing intrusions or violations. The special camera arrangement on top of a radar scope is on display as well.

These recordings are now a valuable and interesting trace from the past, witnessing momentous events like the withdrawal of Soviet forces following the 1968 Soviet invasion of Czechoslovakia and the (sad) conclusion of the crisis, large exercises of the Warsaw Pact forces over the Baltic, or little-known, evident intrusions of Soviet aircraft over Swedish territory, and even the overflight by a USAF Lockheed SR-71, at its typical, extremely speed. This incredible material, visible in the museum in the form of a cyclically-running documentary, can be purchased as well after visiting.

A big component of the museum is dedicated to a large and neat collection of aircraft engines. The aircraft design program of Sweden, based on the SAAB designs from the late 1940s until the end of the Cold War, was supported by jet engines modified mostly by Volvo, starting from British or American designs.

The presentation in the museum allows to learn much about the specific features of many of these aircraft engines, by displaying cutouts, technical drawings, as  well as components of the ancillary systems and utilities (pumps, generators, etc.). Interestingly, a poster-size reproduction of an old picture portrays the local bunker hangar in Arboga (see above).

An interesting display of cockpit panels from Swedish aircraft allows for an analysis of the evolution of their design. An old flight simulator for training purposes, the ubiquitous US-designed Link Trainer, was apparently employed also in Sweden.

Finally, another exceptional feature of this museum is the availability of two simulators of the SAAB Draken and Viggen! These have been prepared making use of sections of their respective fuselages, notably including the cockpit. They make for an unmissable experience for everybody, especially if you already have some piloting experience – in that case, you may have chance to fly one of these two iconic attack aircraft from the Cold War with incredible realism, for example on an intercept mission versus a Soviet cargo, guided by the expert words of an authentic radar controller!

Getting there and visiting

This one-of-a-kind museum on a very interesting and special topic makes for a must-see destination for everybody with an interest in the Cold War. The exact address of the museum is Glasbruksgatan 1, 73231 Arboga. The location has a large parking ahead of the entrance. The premises taken by the collection, on the ground floor of an old industrial building, are compact and easy to tour. Yet the collection is very rich, and a visit interacting with the group of friendly volunteers (some of them speaking English fluently) running the site might easily take  2 hours or more for an interested subject.

Additionally, an experience on the flight simulator is definitely worth a visit on its own. This can be arranged by prior email or call, and combined with the visit. The professional website, with full information on the museum and exhibits in multiple languages, can be found here.

My own exceptional experience on this site together with a friend of mine, which included memorable flights in both Draken and Gripen simulators, was kindly sponsored and arranged jointly by the Volunteers of the Arboga Robotomuseum, in particular Mr. Antero Timofejeff, and by Mr. Erik Mårtensson, both former officers of Sweden’s Armed Forces. To these gentlemen and to the Volunteers go my personal thanks and congratulations!

Military Collections in Sweden – Third Chapter

The rich military tradition of Sweden can be retraced by means of many interesting dedicated collections. Many of them are scattered in the nice southernmost country regions of the Scandinavian peninsula, and make for an interesting detour from the most popular touristic destinations.

As reported in the previous two chapters on the topic (see here and here), the neutrality of Sweden in the major confrontations taking place during the 20th century allowed this northern Country to operate in a unique and original way, especially in terms of military procurement. Besides picking what was actually deemed suitable for their internal needs especially from the West, Sweden managed develop a strong domestic design and manufacturing capability, such to fulfill its own self-defense role in a cost-effective and credible way.

The defense of neutrality was carried out in the air by a strong Air Force, often updated over the years. With the end of communism in Eastern Europe and the collapse of the Soviet Union in the early 1990s, the major threat in the Baltic area came to an end as well, resulting in a major scale-down of this defense force and the disbandment of many military organizations. Correspondingly, memorial museums can be found often close to former airbases. One of them, dedicated to the ‘Scania’ wing F10, in operation since WWII to the early 2000s, is covered in this chapter.

A rather complete collection of aircraft from the entire span of the Cold War can be found in the unusual frame of a private museum, established in the 1960s from the will of the founder to display primarily his own collection of cars. The mix is particularly interesting, witnessing also the close link between Sweden and the vehicle industry of the US, possibly the tightest among all Countries in Europe.

Of course, in the theater of WWII Sweden was politically and geographically in an interesting position as well as later in the Cold War. Its relative proximity to the Third Reich meant it was often overflown by bombers on their way back from missions over mainland Germany. Dogfights and bomber chase missions reached the airspace of Sweden, sometimes ending with either German or Allied aircraft crashing on Swedish territory. An interesting museum covered in this chapter is fully dedicated to the topic.

Photographs in this chapter were taken in the summer of 2024.

Ängelholms Flight Museum, Ängelholm

This nice collection of military aviation can be found on the former premises of the air base of Barkåkra (today Helsingborg airport), which has been the home of the 10th Wing ‘Scania’ (aka. F10 or ‘Ängelholm Wing’) between 1945 until the disbandment of the latter in 2002. Established during WWII, the illustrious history of the F10 wing spanned the entire Cold War, reaching into the 21st century. Correspondingly, the Scania Wing was supplied over the years with a rich inventory of aircraft models, ranging from classic fighters of WWII to the more recent SAAB Viggen and Gripen.

The structure of the exhibition, rather compact in size, is composed of two major areas.

In the first, the history of F10 is retraced especially by means of interesting photographs and memorabilia items. Among the pictures, some portray American bomber crews as well as German fighters landed on Swedish territory, which remained neutral during WWII.

In this area are also a few dioramas and reconstructions of typical military scenes, including a medical room, from the earlier days of operation of the Scania Wing. Everyday items, as well as military training and illustrative material, is presented in display cases.

The second major area is where most hardware of the collection can be found – aircraft, engines, vehicles, and much gear from the days of operation of the F10 wing. Among the earliest models acquired by F10 back in the WWII years was – rather interestingly – an Italian fighter, the Reggiane Re-2000 Falco, a batch of which was obtained from Italy in a supply shortage scenario, where especially the US had halted material export to non-allied countries. Pressed into service with the Air Force of Sweden (and specifically also with the F10 wing) as an interceptor with the locally attributed code of J20, this generally adequate machine was powered by a Piaggio P.XI 14-cylinders radial engine (which according to Roman numbering then often employed in Italy translates into P.11), a 1.040 hp model license-made in Italy, and originally a French design by Gnome-Rhone. A Re-2000 is not on display, but a Piaggio P.XI is! This engine has been quite popular in those years in Sweden, ending up also as an interim power plant for the Swedish own SAAB B17C single-engine light bomber/diver (not to be confounded with the homonym American Flying Fortress).

Close by the P.XI is the oldest aircraft on display belonging to the F10, in the form of a FFVS J22. The company FFVS was actually a Swedish state-managed entity, borne in the years of WWII to cope with the wartime supply requirements on one side and the overbooking of the SAAB plants on the other. Introduced during WWII, this rugged fighter was powered by a Pratt & Whitney R-1830, the ubiquitous Twin Wasp, license-built in Sweden by Svenska Flygmotor. The Scania Wing received the J22 model only in 1945, the last propeller-driven aircraft in its inventory. The exemplar on display looks under maintenance, and is possibly in airworthy conditions.

Next on display is a SAAB J29 Tunnan, with its distinctive barrel-shaped fuselage enshrouding the single, centrifugal flow jet engine. The F10 wing transitioned to jets in 1946 with the early SAAB J21R and the British-supplied DeHavilland DH100 Vampire (named J28R in Sweden). The Tunnan was provided to the F10 wing in 1953, and there it remained until 1963, while more advanced models were becoming available. The engine of the J29 was a DeHavilland Ghost, manufactured under licence in Sweden by Svenska Flygmotor under the name RM2B – an example is on display.

Close to the tail cone of the Tunnan is also a DeHavilland Goblin engine, originally employed on the Vampire.

The longest-lasting workhorse in F10 service has been the SAAB J35 Draken. An exemplar of the J version, the most updated and last (with the actual modification taking place in the late 1980s), is on display. The distinctive bulge for the IR seeker under the fuselage, appearing from the modern F version on, can be checked out from very close.

Interestingly, the Draken is presented with an exemplar of the Rb-28 missile hanging from an underwing pylon. This is a SAAB-modified version of the US-designed Hughes AIM-4D Falcon, an air-to-air missile conceived as an anti-bomber weapon, but hastily pressed into service against Vietnamese MiGs during the Vietnam war, under the wings of the Phantom, and proving very ineffective in the dogfighting role. For the Soviet bomber interdiction role of the Draken, this missile platform was deemed more effective, and it was retained for service for decades in Sweden.

Other missiles, rockets and guns (including a dismounted Aden 30 mm cannon) pertaining to the warload of the Draken are on display as well, together with an interesting console for missile signal testing.

Ahead of the Draken is a memorial wall, and ahead of it is a Rolls-Royce Avon jet engine, displayed as an instructional cutaway – including both the turbomachinery and the afterburning component. License-built in Sweden by Svenska Flygmotor as RM6C, this was the engine of the Draken.

The F10 wing received the SAAB J37 Viggen only after the collapse of the USSR in 1993, marking the beginning of the last, post-Cold War chapter in the history of the unit. Quite elusive due to its adoption only by Sweden, albeit rather successful in its intended roles, an exemplar of this machine can be found in this collection. Specifically, this is a photo reconnaissance version named SF37. Lacking a radar, this model typically operated on reconnaissance missions in a flight of two, together with a radar-supplied SH37 variant.

The Viggen can be neared and checked out entirely with ease, thanks to its positioning on a pedestal. The photo-reconnaissance payload is on display. Under the left wing is a SAAB Rb-04 anti-ship missile. This Swedish own design was conceived for countering invasion starting from the sea. With a radius of 25 km and active radar homing, its warhead was sufficient for knocking out an enemy cruiser with a single hit.

The collection of the Scania Wing also includes the SAAB SK60 trainer, a successful trainer employed for decades, and inducted into the F10 inventory during the 1990s, when the wing took over the basic training role from the F5 wing. Similarly, an ubiquitous Bell 204 (Hkp 3B according to Swedish naming) can be found on display, as it was employed within the F10 for rescue and logistics/transport duties.

Close to the Viggen are further interesting exhibits. One is on the wartime bases (krigsflygbaser, see this post), with models and original signs from one of them.

Another is about weather forecasting within F10. It includes electronic hardware, an entire room with original consoles, and weather balloons, still today employed to carry atmospheric sounds.

A display is dedicated to pilot’s protection helmets, survival kits and ejection seats. Not only in Sweden, the latter have been in the focus of a major technological development over the years of the Cold War. Ejecting from a fast jet in the 1950s was reportedly a highly-risky business, since even when the maneuver was technically successful – i.e. such to take the pilot out of the aircraft alive – the ejection-induced acceleration alone was more than enough to cause serious injury, usually to the spine. Over the years, multi-stage ejection was implemented, allowing for a more gradual maneuver, which albeit remaining lightning-fast, does not inflict so harsh a treatment to the pilot’s body as in the past.

A top exhibit on display is an original cockpit from a SAAB J35 Draken, employed for training purposes. The cockpit is very well preserved, thoroughly described by explanatory panels nearby, and it can be boarded to give you a feeling of the functionality of the onboard systems, as well as of the ergonomics of the cockpit.

Two more training aircraft are included in the exhibition, a SK61 and SK50, both single-propeller machines employed for basic training.

Additionally, the last type in service with the F10 has been the SAAB JAS39 Gripen (from 1999 until disbandment), which is here represented by means of the first serial production machine of the first version (‘A’). This exemplar was actually never pressed in air force service, but it was employed as a test bed for multiple operations, including test firing of missile ordnance in the early 2000s.

Additional dioramas in this compact but rich collection include op-rooms from various ages.

An interesting exhibit is a relatively well-preserved Rolls-Royce Merlin piston enigine, originally powering a British Avro Lancaster bomber which sank south of Trelleborg in the Baltic Sea, presumably early in 1945 after a bombing run over Germany.

Finally, on the outside it is possible to find a British Bristol Bloodhound Mk II missile. This SAM supplied a squadron of F10 wing, complementing the air defense role in proximity to the airbase.

Getting there and visiting

The name of the museum in the local language is Ängelholms Flygmuseum, which translates into Ängelholm Flight Museum. It is located on the southwestern border of the former airbase of Ängelholm, easily reachable at the address Drakenvägen 5, 26274 Ängelholm. This town is 15 mi north of Helsingborg along the E6 highway.

Large parking ahead of the entrance. Nice shop with books, toys and gadgets by the ticket office. The museum facility is rather compact, yet a visit may easily take 1.5 hours for an interested subject, when carefully checking out all items on display and taking pictures. Descriptions are in double language, Swedish/English, allowing for an informative visit even if you are from abroad.

Museum of Forced Landings, Morup

The Museum of Forced Landings (in Swedish language the museum is named in a rather different way, ‘Morups Samtidsmuseum’) is a one-of-a-kind collection of remains and traces from air crashes or forced landings taking place during WWII in Sweden. Run by a lively group of dedicated enthusiasts, the display is extremely well-crafted, offering not just an array of many and diverse relics from aircraft wrecks, but for each of them a complete synopsis of the story behind that specific flight – and the crewmen who were on board.

Furthermore, in my case I was accompanied by a very knowledgeable English-speaking gentleman for the entire duration of my visit, making the experience even more engaging.

The exhibition starts with a display of general maps of the crash or forced landing sites. A sharp increase towards the end of the war is evident, due to the increase in the number of bombing raids over the center of the Third Reich. The crashed aircraft are mostly from the US and Britain. When hit over Germany but still airworthy, Allied crews attempted an escape to neutral Sweden, to avoid capture by the Germans.

Of course, Sweden was a neutral country, hence all grounded crews, irrespective of their nationality, were interned, albeit in more than decent conditions, especially compared to German or Soviet prison camps.

A map of the internment location in Sweden is presented as well. Clearly, also German aircraft crash-landed in Sweden. Crews of opposing nationalities were interned in totally different locations. Rare photographs from these sites are on display.

Then, one by one, the display cases describe each a notable forced landing, retracing its timeline, and showing some relics from the wreckage, as well as personal items belonging to the crew. Nice detailed scaled models and dioramas of the accident complete the reconstruction.

Among them are a German Messerschmitt Bf110 attack aircraft, with a fragment of the canopy as well as other parts on display, Norwegian training aircraft, a German Junkers Ju-52 transport, with an entire control column put as an exhibit.

The bombsight, radio and other instrument goggles belong to a German Heinkel He-111 bomber landed on ice.

One of the plots documented in the deepest detail is that involving Lt Edward E. Phillips, of USAAF 354th fighter group, which flew escort missions over Germany from Baxton, England, with North American P-51 Mustang fighters. On the 15th of April 1944, on return from a mostly failed bombing mission over Germany in bad weather, Lt. Phillips aircraft was chased north by a Bf109. He was hit over southern Sweden, bailed out but the parachute failed to deploy. He was killed instantly, and his aircraft impacted soft terrain and sank so deeply due to its own energy that it almost disappeared into the ground – and there it remained for 40 years. In the 1990s an excavation attempt was carried out by the future crew of the museum, uncovering substantial remains of the aircraft, including many parts, cockpit gauges, machine guns, an entire landing gear leg, and more.

A link was established by the local crew with the former wife of the man in the US, and the story hit the news. A memorial was inaugurated on the location of the crash.

Another American aircraft with a story to tell is a Consolidated B-24 Liberator. This time the aircraft managed to crash land under control, and the entire crew of 10 was saved and interned. Sgt Robert C. Birmingham, part of the crew, visited the locations of his adventure in Sweden more than once with his family.

More accidents described in the display involve British and German aircraft.

In an adjoining room, an impressive collection of quality scale models reconstruct many of the aircraft in service within the Air Force in Sweden, including details such as different celebration markings and camo coats. Among the artifacts and memorabilia items on display in this part is an autographed photo of WWII German ace Günther Rall.

In another small hangar is an interesting addition to the collection, mostly centered on aircraft engines. Engines from crash-landed aircraft, significantly damaged but undergoing a display-oriented cleaning and refurbishment, make for an unusual and interesting sight.

Outside is also a small collection of classic cars in pristine conditions.

Getting there and visiting

The museum is called ‘Morups Samtidsmuseum’ in Swedish language. It can be found right along the road N.768 about 6 miles north of the coastal town of Falkenberg, 0.25 miles north of the small town of Morup. The exact address is X9MP+84 Morup.

A visit may take about 1 hour, more when stimulating further telling by the very enthusiastic crew of the association running the museum.

Please note that no credit cards are accepted, only cash is – unless you are entitled to employ electronic payment methods allowed for citizens or residents of Sweden.

The website, partially under construction as of spring 2025, can be found here.

Svedino’s Automobile and Aviation Museum, Ugglarp

This unusual exhibition originates from the own collection of Lennart Svedfelt, a prominent Swedish stage and TV entertainer borne in 1924 and known as ‘Svedino’. The man started purchasing cars and planes for the purpose of collecting them, in an era when a similar activity was hardly heard of. In 1961 he opened his collection as a permanent display, the first museum dedicated to cars in Sweden. Over the years, and even following his passing, the museum continued to grow, reaching more than 100 cars and 40 aircraft on display today!

Even though this is not an eminently military museum, despite the cars being beautiful civilian cars, most aircraft on display are military machines, including some remarkable items – therefore, Svedino’s perfectly fits within this chapter!

The cars on display make for a really unique collection, in and out of Sweden. A remarkable feature is especially the number and uniqueness of US-made cars from the inter-war period between WWI and WWII. In a first building, these include models by Chevrolet, Buick, Dodge, Nash, Oldsmobile, and more!

Also some classic models from European manufacturers, like Opel, are on display. A special rarity is an Adler Trumpf from 1934. Adler, a German company from the 19th century active in the manufacture of petrol engines, operated in the car market for a relatively short time, roughly coincident with the Third Reich period. They made cars in the intermediate price segment, with good success. The company changed business following WWII, making Adler cars interesting collectible items representing car-making from a specific era.

As expected from a Swedish museum, a full array of classic Volvo is on display! These include small trucks and saloons, and interesting models like the PV36 from the inter-war period. Similar to the PV830 and the iconic PV444 from the immediate post-WWII years, an influence of the contemporary American designs is undeniable in all these models.

Also on display are more modern vehicles employed as state cars. An interesting item is a very old Gräf & Stift, an Austrian luxury sedan from before WWI, salvaged from the bottom of a Swedish lake after spending there more than 40 years, and acquired by the museum.

Two interesting cars on display are personal designs from the early 1950s. In Sweden it was possible at that time to introduce privately-built cars, provided they could sustain a compliance check. An example of a fantasy car, with a rather aggressive design and physically assembled from parts of other cars, is on display. It was never completed nor allowed on the road. Another example, designed and made by the son of the industrialist Wennberg, reportedly roamed around all over the 1950s! This unique exemplar is on display with ‘factory markings’ HW.

In a second adjoining building, a really valuable collection of even older cars, dating from earlier than 1930, is on display. Also here most items in the collection are from the US, a really rare sight on this side of the ocean! Looking at the elaborated labels of these oldies, made by Ford, Anderson, Seneca, and thinking of the craftsmen who personally assembled them back in the America of the early 1900s is really thought-provoking!

Among the most unique cars on display is a Pierce-Arrow from 1918, sitting alongside a Haynes from the same year.

Moving on to another adjoining hall, here cars are on display alongside a few classic planes from the first half of the 20th century. A DeHavilland Moth, a Götaverken GV-38 seaplane (a licence-built Rearwin Sportster, a US design), as well as a German Klemm Kl-35 and a Focke-Wulf FW-44 designs, are on the list together with more light airplanes and a few engines.

The latter include an original Rolls-Royce Goblin and Avon, respectively from a DeHavilland Vampire and a SAAB Draken, both in service with the Air Force of Sweden during the Cold War.

A focus of the exhibition is on the memory of a pioneer of Swedish aviation industry, Enoch Tulin, who is the author of many ‘firsts’ in the aeronautical history of this Country – the largest aviation workshop to date before WWI (with 900 employees), the first air mail service, the first air rescue mission, and more. A graduated engineer, flight instructor and early aerobatic pilot, Tulin died in an airplane crash in 1919, after gaining unquestioned prominence in many fields of aeronautical industry and operation in his era.

A final adjoining hall concludes the oldest part of the exhibition premises. Here the spotlight is on a few fighters from the Cold War era, namely a SAAB J29 Tunnan, two DeHavilland Vampire, and even a SAAB J35 Draken.

The latter is really a unique exemplar. As can be guessed by the monstrous red and white spine on the nose cone, typical to experimental aircraft and not a feature of the production machine, the one on display is actually the first prototype!

Another curious item is a Soviet-made Kamov Ka-26 helicopter. Alongside the helicopter is a vintage advertisement from 1975, written in Swedish, and made by Aviaexport, a Soviet agency for the commercialization of Soviet aeronautical products abroad. Borne as an import-export, Aviaexport acted also as a recipient of foreign certification rules, spreading the growing body of western aeronautical regulation within the Soviet design bureaus, to the aim of keeping the quality standard to a level sufficient for commercialization in foreign countries. Actually, thanks to Aviaexport the Kamov Ka-26 received a type certification in Sweden, which allowed its commercialization and regular employment there. Aviaexport is still existent in today’s Russia.

Interspersed between closely-packed aircraft are more cars, including a beautiful Jaguar Mk V and an East-German Trabant, as well as aircraft engines.

A massive Wright Cyclone R-3350 is among them – the power plant of the Lockheed Constellation and Douglas DC-7, often considered the pinnacle and swansong of American piston power, this massive 1.2 tons, 18 cylinders engine produced 3.700 hp of shaft power!

Svedino’s aircraft collection is mostly hosted in a modern hall added more recently beside the original museum’s building. The first item on display is an original Junkers Ju-52! This aircraft is among those license-built in Spain. It operated for some time as far as in California in the 1970s, being later transferred to Ireland, and finally here. The camouflage and markings reenact those of a Third Reich’s Luftwaffe machine force-landed in Sweden during WWII. The cockpit of the Ju-52 has been reproduced separately, to allow checking it without boarding this precious aircraft.

As expected for a Swedish aircraft collection, the most prominent models which have served in the local Air Force are represented. These include a SAAB J32B Lansen, a Cold War attack aircraft from the 1950s, a SAAB SK60 trainer, and a SAAB J35 Draken – a production machine, not a prototype like in the previous hall.

These aircraft are presented alongside their engines. The Swedish licence-built version of the Rolls-Royce Avon, named RM6A, powered the Lansen and later the Draken.

The latest addition to the SAAB heritage on display is the J37 Viggen, here presented in the nice and distinctive camo coat of the Air Force of Sweden. This is presented alongside its mighty engine, the RM8A, a modified version of the Pratt & Whitney JT8D turbofan.

Additionally, a display of an open nose cone allows to see the arrangement of the radar antenna of the Viggen.

An interesting display case hosts the instrument panels, radar and reconnaissance gear of the Lansen, Draken and Viggen, as well as a collection of flight helmets and pilot’s gear, showing the evolution of this technical material over time.

But the collection of Svedino’s is not limited to aircraft in service in Sweden. A Lockheed F-104 Starfighter from the Air Force of Denmark is on display, next to a Gloster Meteor early twin jet. The blue exemplar on display is a former factory demonstrator originally employed by Gloster, and later sold to Sweden for target towing (in a batch of seven aircraft).

A rarity to be found close by is a Percival P.66 Pembroke, a twin-engined multi-purpose transport from the early 1950s, employed for training and passenger transport within the Air Force. Manufactured in Britain in just 128 exemplars, this type was mostly sold abroad to Western-European Countries and in Africa. Sweden originally got a batch of 16.

Another British type on display is a Hawker Hunter, which was actually employed by Sweden as a stop-gap model in the late 1950s, waiting for the completion of the design and the entrance into service of the J35 Draken.

Another Soviet addition to the collection is a MiG-21. A Cold War veteran, this exemplar is Soviet-built, and served in Hungary until 1982 and later in the Latvian SSR.

A recent addition to the exhibition is a Douglas Skyraider! Possibly overshadowed by the illustrious career the type enjoyed in the US Armed Forces, a part of the history of this massive attack aircraft is about Sweden. Some 13 exemplars were actually purchased by Sweden for target towing in the mid 1960 from Britain, which had got a larger batch from the US. The exemplar on display is an AD-4W, the early warning version of the Skyraider. It is currently (2024) being refurbished.

Among the biggest additions to the aircraft collection is actually an English Electric Canberra. As typical to this type, employed by the British for the first, high risk overflights of the Countries of the Soviet bloc before the high-performing Skunk Works aircraft became available, the Canberra (including its modified Martin version in the US) was employed for quintessentially Cold War signal intelligence missions opposite the Soviet Union. Two exemplars were employed also in Sweden from the early 1960s until the mid-1970s, and one of them is that on display.

A curious item also on display is a one-off design which won a competitive call of the Aviation Engineering Association in Stockholm in 1988, and which was later actually built by its designers. Unfortunately, it was eventually never tested due to one of the owners need to quit for health issues when the aircraft was undergoing a certification test for obtaining airworthiness. The name of the prototype is LLS-1.

Scattered among the aircraft are more engines, radars, consoles, simulators, and more aircraft than described, making for an overall very rich and interesting visit.

Getting there and visiting

Svedinos Bil & Flygmuseum – this is the name of the museum in the local language – can be found in a nice countryside 15 miles north of the port town of Halmstad. The exact address is SE-311 69 Ugglarp.

The premises are rather compact, with a large parking ahead of the entrance. Fresh cookies, homemade sandwiches and cakes are available for a light lunch in the exotic lobby, matching in style with this unusual collection.

A visit may take 2 hours for an interested subject. Most items are described with modern panels in double language Swedish/English, making the visit very informative. The website with logistical information is here.

The events taking place on the geopolitical stage during the last decade of the Cold War – the 1980s – gave little indication of the imminent collapse of the Soviet-led Eastern Bloc (1989-1991). Correspondingly, looking at the amount of technology developed and deployed in the military field during the late, hi-tech stage of the Cold War, it is easy to notice that opponents on both sides of the Iron Curtain dedicated a significant (and even increasing) budget in preparation for a possible total confrontation. Reading papers and specialized books from the time, the outbreak of an open conflict, such to put a violent and abrupt end to years of opposition between the two opposing systems by recurring to nuclear warfare over the territories of Western Europe (most of them belonging to the NATO alliance, and all being substantially more militarized than today), was not deemed just likely, but more as a matter of time.

The БАРС system – The tropospheric network of the Warsaw Pact

In that era of extreme tension, it is not surprising that one of the most sophisticated and expensive assets developed and deployed jointly by all Nations in the Warsaw Pact, of course led by the USSR, came alive. History would cut its life short though, and as soon as the Warsaw Pact disintegrated, as a result of the opt-out from communist dictatorship of all Countries in Eastern Europe, this asset was decommissioned. This system was the tropospheric communication system ‘БАРС’, a Russian word reading ‘BARS’ and meaning ‘snow leopard’. The name stands as an acronym for four words in Russian, which translate into something like ‘Sheltered autonomous radio communication system’.

The idea put forward by the Soviet top-ranking military staff in the early 1980s (prior to the onset of Gorbachev administration) was that of a system capable of transmitting complex orders (not just simple signals, like for opening a bunker door or silo, but articulated messages) in a safe encrypted way, at a long distance and minimizing the chance of a complete breakdown even in case of an enemy nuclear attack. Despite being not new, the concept of a resilient and reliable system, such to allow exchanging significant amount of data without relying on cables, had been tested in earlier stages of the Cold War only for short-radius operations. Mobile transmitters/receivers, loaded on purpose-designed trucks, allowed for a reduction of the risk of a direct hit from an attacker, and for a quick redeployment in case of need. However, for the amount of data and range required for the coordination of a war scenario, involving many different Countries, and geographically encompassing an entire continent, a different system was required, capable of transmitting more massive data flows on longer distances, with a reduced risk of a sudden or complete interruption.

The БАРС system was based on a certain number of stations, scattered over the territory of the Countries of the Warsaw Pact. Each node was built as a bunkerized, manned military installation, featuring high-power, high-frequency fixed antennas emerging from the ground, and an underground shelter protecting all the technical gear required for manipulating the data to be sent or received, interfacing with the other existing local (i.e. national) networks for military and executive governmental communication, and of course managing the tremendous amount of energy required to pump a long-reaching signal into the ether.

Laying on the front line with the West, hosting a Soviet contingent of some hundred thousands troops (see here and links therein), aircraft (see here), missiles (see here) and nuclear warheads (see here), and being a key-ally of the USSR in case of the outbreak of an open war (at least until late 1989), the German Democratic Republic (or GDR, or DDR in German) was clearly included in the БАРС network from the initial drafting phase. Similarly, Poland, Czechoslovakia, Hungary and Bulgaria, and of course the Soviet Union (which included Belarus and the Baltics, and stretched west to Kaliningrad), all had БАРС stations on their territory. Stations were located at a range of a few hundred miles from one another, thus within the range required for each of them to communicate with one or more of the other nodes. Data (e.g. orders, reports or authorizations) input locally could be relayed along the network through intermediate nodes, down to the intended destination node. There were 26 nodes in total, of which four were in the USSR.

The Wollenberg site – Bunker 301 ‘Tushurka’

The GDR in particular had three stations built, all along the border with Poland, and located east of Berlin – namely Station 301 in Wollenberg, at the same latitude of Berlin, Station 302 in Langsdorf, towards the Baltic coast, and Station 303 in Röhrsdorf (near Königsbruck), not far from Dresden in the southeast of the GDR territory. The first among them, the Wollenberg site (codenamed ‘Tushurka’) could communicate with the other two national stations, as well as with Station 207 in Poland, from where data would be transmitted further down the network, towards the USSR.

The site was built by the GDR state, with technical hardware coming from several Countries within the Warsaw Pact, and most of the military hi-tech components manufactured in the USSR. The actual site (similar to its sister sites) was built in the frame of a highly secretive operation. The staff comprised about 60-70 men, the majority of which were military, where about 15% were civil technicians. Maximum security clearance was required, due to the top-secret nature of the installation and of the overall БАРС system. The bunkerized part of the installation was only a component of the larger premises of the base, camouflaged within the trees on the side of low-rising hill.

As pointed out, the immense spending required for setting up this multi-national hi-tech military communication system, which was extensively tested and completely commissioned (as a network) by 1987, did not save it from a quick demise and disappearance. In particular, Station 301 went definitively offline as early as August 1990.

However, the fate of the Wollenberg site was not so sad as that of many former Soviet or NVA (i.e. the East German Army) installations in the GDR. The high-power antennas were torn down, but except from that, little material damage was inflicted to the buildings and bunker on site. The place was basically shut-off and left dormant, until when a society of technically very competent local enthusiasts started a plan to preserve and open it to visitors, as a memorial specimen of the technology of the Cold War years.

A visit to the Wollenberg bunker site reveals a tremendous deal of interesting details, very uncommon to find elsewhere in the panorama of Cold War relics around Europe. Thanks to a careful preservation and restoration work, the bunker has most of its original systems still plugged to the grid and lit-up – some of them are reportedly still working! Even though the communication networks have been severed, the experience in the bunker is really evoking, and the atmosphere – with all the lit-up cabinets, lights, CCTV cameras, 1980-style screens, etc. – closely resembles that of the bygone era when БАРС was operative!

This report and photographs were taken during a private visit to the bunker, carried out in the Summer of 2023.

Sights

A visit to the the installation in Wollenberg starts from the original high-security access gate. As you may quickly notice when passing through it and getting a first view of the site, the state of preservation is exceptional. Except for the lack of military staff around, everything looks mostly like in the years of operation.

A group of soft-construction service buildings and a reinforced multi-entry garage constitute the first – and visible – nucleus of the installation. All buildings are painted in a camo coat.

A former building for the on-site staff has been turned into a permanent exhibition, with memorabilia items from the Cold War years, when the Nationale Volksarmee (or NVA, the Armed forces of the GDR) cooperated with the Soviet Red Army and the national Armed forces of other Countries in the Warsaw Pact.

A meeting room, now employed also for small gatherings, is especially rich of interesting and diverse items, including emblems, books, memorial plates and pennants, as well as TV screens, hi-fi systems and and beamers from the era.

Another room has been set-up as a control center for the base, with an original console and regional maps.

Compared to military bases (for aircraft or tanks), the Wollenberg installation is rather compact, with a main road giving access to most of the (not many) buildings on site, as well as the bunker. Actually, the bunkerized part was built under a low-rising hill, with the antennas originally standing on top of it. Access to the bunker is possible either by climbing uphill on the main road, or through a suggestive original pedestrian tunnel. The latter starts from within the service building itself, and – somewhat unexpectedly, for an underground installation – it climbs uphill, while keeping beneath the surface of the hill side slope. The lower end is guarded by an original CCTV camera.

At the top end of the tunnel you can find the actual access to the bunker. The design and reinforcement level conferred grade ‘D’ protection according to the military standard in use at the time, with grade ‘A’ being the strongest. Access is through an airlock, constituted by two tight doors at the opposite ends of a small vestibule built in concrete. This design allowed protection from the blast of a nuclear device.

Notably, the locking mechanism of the tight doors is Soviet military standard, which can be found in high-value installations like nuclear depots elsewhere in the Eastern Bloc (see for instance here in Poland, and here in Czechoslovakia).

To the visitor with some experience of Cold War installations, it will be apparent from the very start of the tour that the state of conservation of the bunker, including the systems in it, is exceptional, similar to the rest of the Wollenberg site. The original warning lights and the CC-TV camera for identifying people at the entrance are still in place.

Next to the entrance, a control room with technical gear for checking-in can be found – including original dosimeters for radiation and chemicals, mostly Soviet-made. Looking inside these devices is possible, and reveals a great deal of sophistication in the design and realization of the military-grade material from the time.

Showers and sinks for washing, as well as canister for disposing of contaminated clothes, are located in the same area.

Upon getting access to the sealed area of the bunker and passing by the decontamination facility, you find yourself on the top floor of the underground bunker. The high-technology gear required for the transmission/reception of data on the БАРС network, as well as the interface with other national communication systems, required for receiving data, issuing orders, etc. over the territory of the GDR, were located on this floor.

Two symmetrically placed rooms host two twin transmission centers for the БАРС system. A single manned console can be found in each of them, surrounded by electronic cabinets and switches. At a closer look, all the material herein is Soviet made, and labeled in Russian only.

On the wall ahead of the console station is a set of cables, communicating with the antenna and allowing to set the orientation and monitoring its status.

The actual signals transmitted to the antenna, or received from it, traveled along special hollow ducts, with an almost rectangular section. Bundles of these ducts can be found in the ‘Sender’ (which means ‘transmitter’ in English) room, immediately next to the room where the manned console is.

The modulation and demodulation of the signals going out and coming in respectively through the antenna on top of the bunker required some special pieces of electronics, which included the Soviet-designed KY-374 klystron (codenamed ‘Viola’), a component to be found in the cabinets of the ‘Sender’ room.

Following the hollow ducts, it is possible to find where they finally exit the usually manned part of the bunker, bending into receptacles and leading outside. Piping related to other systems, including air conditioning, can be seen as well crossing or running in the same narrow technical corridors.

Beside the consoles monitoring the antenna and the data flowing through it, a kind of operative room for communication can be found, where consoles allowing to receive and forward data and communication to/from all systems are on display. This largely original room features consoles of different levels of technology.

Original explanatory schemes showing the basic features of the БАРС system are on display in that area – in Russian!

An adjoining room features the cabinets required for making all these system work. The cabinets are really many, with a significant share of material manufactured in the USSR. The sight of all these cabinets together is really impressive, and tangibly provides the feeling of a high technology, sophisticated and expensive design. It compares well, but in a largely up-scaled fashion, to the electronics to be found in some special communication bunkers on the western side of the Iron Curtain (see here).

Interspersed with the original arrangement of the cabinets and consoles are some displays of original material. These include specimens of different types of cables for signal transmission – some of them hollow and pressurized, others featuring impressive bundles of thinner wires – the KY-374 klystron, and other once top-secret core components of the БАРС transmission system. Also on display is one of the few remaining parts of the original system of antennas, once on top of the bunker. The antennas were the only part to be physically torn down when the system was decommissioned, upon the demise of the Warsaw Pact and the end of the Cold War.

The bunker was manned by military and technical staff 24/7. Furthermore, as typical for bunkers from the Cold War era, provision was made at a design level to allow the staff to live isolated within the bunker for an extended period of time, in view of the eventuality to face a nuclear fallout scenario.

On the same floor as the technical rooms, the commander of the station had his own private room. This is still adorned with typical Soviet iconography, as well as everyday material from the age when the bunker was operative.

A small canteen, with a kitchen and a modest living room, can be found at the same level. An original storage room has been employed to gather examples of everyday products, like soap, skin care cream, etc., as well as canned food, cocoa, and beverages of all sorts.

This represents a very rich catalog of now largely defunct and forgotten labels, from the age and regions of the Eastern Bloc (and especially from within the GDR). Also on display are bottles of spirits, likely still very good!

The visit proceeds then to the lower floor, which can be reached through a flight of metal stairs.

The lower floor host the plants required for the regular operation of the entire bunker, such to guarantee operational ability even in case of an enemy attack carried out with nuclear, chemical or biological warfare. The air filtering and conditioning system is very modern. Beside typical filtering drums for particles, to be found also in other bunkers (see for instance Podborsko here), you can see a bulky filtering and climate conditioning system, neatly arranged within two parallel square-shaped ducts. Filtering against chemicals as well as biologic agents was carried out employing special active filters.

Sensors for the level of contamination of the bunker air can be found in different rooms. Much material here is standard Soviet-made.

Systems for water pumping and compressed air can be found as well, including compressors, pumps and reservoirs. Looking at the always interesting factory labels in this area, it is easy to find export products of Bulgaria, Romania and other communist dictatorships of the era. Of course, much hardware is also manufactured in the GDR.

Electricity was supplied from the outside grid, yet capability for self-sustaining in case of a grid loss (for instance in case of war) was implemented as well. Three big German-made Diesel generators have been put in place, and are still in an apparently good condition.

Another example of the high technological standard reached in the late Cold War era is represented by the control room for the plants within the bunker. A manned control station, with a console and a direct view of lit-up cabinets, reporting the status of the various systems running in the bunker, compares well with control rooms of large industrial plants in operation today.

Carefully kept in its original status, with many of the electric links and cabinets still working, the sight of this room is especially evoking.

Also on the lower floor are the sleeping rooms for off-duty staff. Typically, this was not employed except for drills, when the bunker could be sealed to simulate operations in case of the outbreak of hostilities.

Back to the upper floor, it is possible to exit the bunker via a stairway and through a side gate. You will find yourself on top of the low-rise hill where the bunker has been dug. Here the concrete base of the crane where the БАРС antenna used to sit are still visible. Notably, these antennas were much smaller than the tropospheric antennas employed for the TROPOSCATTER system of NATO. This was the result of a different bandwidth employed for transmissions. Therefore, even in the days of operation, the antennas on top of the bunker were not as sizable as those of TROPOSCATTER installations (which were enormous in size).

Looking closely, in the top area of the installation, the duct for supplying the Diesel oil tank of the bunker can be found, similar to sensors for radiation and other atmospheric parameters (similar to what can be found also in other nuclear-proof bases, for instance here). These allowed to monitor the conditions of the outside air, detect an attack and trigger or manage the sealing of the bunker in case of need, by locking all the tight doors.

This access to the bunker is fenced by the original electrified fence, severing this area from the rest of the installation through a further layer of security.

All in all, a visit to the Wollenberg bunker offers an incredible insight in a fascinating and crucial field of warfare – data and communication exchange – as well as a lively and evocative display of a late Cold War hi-tech installation from the Soviet side of the Iron Curtain!

Getting there & Visiting

The German name of the Wollenberg bunker is ‘Militärhistorisches Sonderobjekt 301 Wollenberg’. It can be reached very easily with a car. It can be found in the open countryside along the regional road 158, driving about 35 miles (about 1 hour) northeast from downtown Berlin towards Poland. The exact location is between the small village of Höhenland (~4 miles) and the more sizable Bad Freienwalde (~6 miles). There is a large parking area immediately next to the road, giving direct pedestrian access to the premises of the former military installation. Despite being placed very conveniently, the site is rather elusive when passing by, since it is hidden in the trees and not directly visible from the road. The address corresponding to the place in Google Maps is Sternkrug 4, 16259 Höhenland. The inconspicuous village of Wollenberg, giving the name to the installation, is just nearby, but it is not crossed by the regional road, and it should not be employed for pointing this destination with a nav.

The Wollenberg bunker is a listed historical installation. It is perfectly maintained, privately managed, and it can be regularly accessed with guided tours. These are offered typically one day per week in the summer, or by prior arrangement. Possibly the best option for getting the most out of your visit is getting in contact with the group of very knowledgeable enthusiasts running the place. The official website is here (do not be discouraged by the ‘static’ appearance of the website, they are very active, and they shall typically answer your inquire).

My visit was planned by initiative of Dr. Reiner Helling (see also here), and we visited in a group of three, including the guide (Dr. Michael Schoeneck, a former engineer, with a profound knowledge of any technical aspects related to this installation), which happened to be a perfect option for touring also the narrowest receptacles of the bunker. Visiting in groups too big may be not advisable, since the rooms and corridors are rather narrow, and the place may turn overcrowded for interacting with the guide and for taking good pictures. I think the visit – including the technical content – may be tailored to the needs of the audience. For technical-minded subjects, historians and former military, a visit may take about 2-3 hours (the latter was my experience). In my case, the guide could understand but not speak fluent English, yet Dr. Helling could translate with ease all the explanations. Of course, if you have at least a basic knowledge of German and of the technical material you are looking at, this may simplify your visit, which is in any case highly advisable for those interested in military technology and the Cold War.

The Aeronautical Museum of Belgrade

With a few parallels in aviation history, especially in the years immediately following WWII, former Yugoslavia benefited from supplies by a great number of countries. As a matter of fact, the air force of this newborn communist republic was formed at first from leftovers of retreating Germany and conquering Britain, followed by the establishment of a supply line initially from the USSR, and later the US and again Britain.

The special political ability of marshal Tito, who ruled uncontested as a communist dictator since the foundation of Yugoslavia in 1945 until his death in 1980, and the credit he benefited from especially in Britain, allowed him to keep out of the sphere of influence of the USSR since 1948. In a strategic position on the border with NATO countries like Italy and Greece, Tito adopted a detente policy of ‘equal-distance’ between the two opposing blocs over the Cold War period (even though NATO did not trust him fully, as testified by the deployment of a SAM defense line in northeastern Italy, see this post).

Of course, most of the military supply was of Soviet make, especially after the death of Stalin and well until the end of communism in Europe and the bloody fragmentation of the Yugoslav state. However, concerning civil aviation, autonomy from Moscow allowed the adoption of western aircraft, like the French Aerospatiale Caravelle and much of the Boeing and McDonnell-Douglas inventory, in the major national airline JAT – something which happened very rarely anywhere in the communist bloc over the years of the Cold War, another notable instance being Romania, again a ‘semi-autonomous’ communist dictatorship, who refused the Soviet Tupolev Tu-134 in favor of license-built British BAC 1-11s.

Another effect of the autonomy from the USSR was the creation of a national aviation industry, which especially in the case of SOKO, produced military trainers and light attack aircraft of good success, which despite ageing, are still flying today.

More recently, the fierce conflicts raging over the Balkans in the 1990s have created a major active front for modern aviation, where the air force of Serbia – which inherited the geographically central part of Yugoslavia and its capital city, Belgrade – confronted the NATO alliance in an open conflict. The unbalance of forces allowed the western coalition to quickly establish air superiority, which did not come without a few notable material losses however.

A rich display of this peculiar aviation history, actually tracing back to WWI and the early years of aviation, can be found in the Aeronautical Museum of Belgrade, which despite being in today’s Serbia, acts as a kind of Yugoslav Aviation Museum. As a matter of fact, it was founded as such back in the years of Tito, and opened in its current building nearby ‘Nikola Tesla’ civil airport of Belgrade in 1989, when Yugoslavia was still a reality.

This short post provides an outline of what you can find in this museum, with photographs taken on a visit in April 2019.

Sights

The museum occupies a relatively large area in the vicinity of the airport of Belgrade, and is made of an open-air exhibition, open-air storage area, and big mushroom-shaped building hosting an indoor exhibition.

The ‘gate guardian’ is a SOKO J-21 Jastreb, a nice light multi-role aircraft from the 1960s, powered by a British Rolls-Royce Viper jet engine.

Indoor exhibition

The entry hall of the mushroom-shaped building features is a good example of the architectural style from the late communist era. The ground floor hosts a small exhibition about the early days of aviation in the former region of the Balkans, with documents from WWI years. Among the items on display, you can find early pilot’s licenses from notable war pilots, likely granted after training abroad, and actually written in French.

The main hall of the museum can be found upstairs. This large can be walked on two levels. Most aircraft are to be found on the lower level, but a few are suspended to the glassy circular sidewall of the mushroom, lighted from behind by the sunlight – so that taking pictures is just a nightmare!

The centerpiece of the collection is an exemplar of the SOKO J-22 Orao, a twin-engined – two Rolls-Royce Viper turbofans – light ground-attack and trainer aircraft from the 1970s. Designed jointly by Yugoslavia and Romania, this model equipped the Yugoslav (then Serbian) air force during the 1990s, where a handful exemplars are still flying today.

Indeed a clean design with an interesting performance, this aircraft was possibly the last heir of the Ikarus-then-SOKO lineage, originated back in the years before WWII. In this respect, some unique exemplars of aircraft are preserved in this museum, witnessing the existence of a school of skilled aircraft designers in Serbia, not much known in the western world.

A key figure of the Ikarus design bureau, Dragoljub Beslin led the design of Ikarus S-451, a nice, very small, twin-prop attack aircraft flown in 1951, especially designed to sustain high load factors in maneuvers at high speed.

Another unique specimen is the twin-jet Ikarus 451M, the first jet aircraft built by Yugoslavia. Same designer as the S-451, this unusual jet-engined taildragger flew in 1952, but was soon superseded by more modern models, in those years of quick-paced development of aviation technology. Again, the engines were from the West, in the form of two French Turbomeca Palas turbojets.

Another member of the ‘Ikarus 451’ family – it must be said this Yugoslav one is likely the oddest model numbering systems ever created… –  the T 451 MM Strsljen (Hornet) features a more convincing configuration, resembling the single-engined British BAC Jet Provost and the Italian Macchi MB 326, both rather successful trainers from the late 1950s. On display is actually the ‘Strsljen II’ version, which is a attack/training version with more thrust than the first series aircraft. This model was conceived to operate from unprepared runways, and featured two Turbomeca Marbore II French turbojets. The aircraft flew in 1958, but an air force contract was not granted.

Some functional wind tunnel models of other aircraft, actually never reaching the 1:1 prototype stage, are on display. These include a rare ekranoplane design, the UTVA 754. With a mechanic-monster-like appearance like all ekranoplanes (the most famous being probably the Bertini-Beriev preserved at the Russian Air Force Museum in Monino, see here), this machine was designed in 1982 in the then-Yugoslav town of Zagreb, today the capital city of Croatia.

A medevac aircraft conceived for easy conversion between floats and wheels, the UTVA 66H can be visited also inside. The indigenous SOKO is represented by a number of models. These include the SOKO G-2 Galeb, a successful trainer/light attack aircraft from the 1950s, built around a single Rolls-Royce Viper turbofan. During its long history it was exported to several international operators, and gave birth to the more recent SOKO J-21 Jastreb. The Galeb was in service with Serbia until 1999.

Another section of the museum features aircraft of foreign make which witness the intricate history of alliances of both the pre-WWII Kingdom of Yugoslavia and the post-WWII communist Yugoslavia. Most remarkably, these include a Messerschmitt Bf-109-G! The history of this particular aircraft is not very clear, some sources stating it was captured from Bulgarian air force. As a matter of fact, Yugoslavia acquired about 70 Bf-109-E from Germany in 1940, which in turn furiously invaded from north in a quick an violent campaign in spring 1941.

Next in line is nothing less than a British Hawker Hurricane! A group of Hurricanes were acquired from Britain in the immediate pre-war years, and even license-built in Belgrade in a small number – Yugoslavia apparently purchased aircraft seamlessly from both opponents at the outbreak of WWII. Later on, Hurricane-equipped squadrons of Yugoslavia fought back on the side of the Allies from bases in southern Italy, finally regaining control over the Balkans.

In a similar fashion, a Supermarine Spitfire Mk.V witnesses the involvement of British-supplied national air force squadrons in the liberation of Yugoslavia from the German invaders.

In the closing years of WWII, Yugoslavia benefited also from the help of the USSR. This is witnessed by a massive – and pretty rare, out of former soviet republics! – Ilyushin Il-2 Sturmovik. This big attack aircraft, possibly the most famous Soviet aircraft of WWII, equipped three squadrons in the Yugoslav air force, and helped in the fight on the so-called ‘Srem front’ north of Belgrade. An often overlooked sector of the European front, substantial operations were carried out since late 1944 until April 1945, with the forces of Nazi Germany slowly retreating under the offensive of the Red Army (including Bulgarian divisions) and of Yugoslavia from the south. These operations involved 250’000 troops on either side, thus engaging the Germans and draining resources from mainland defense. At that time, an entire division of the Yugoslav air force were equipped with this aircraft type, kept in service until the 1950s.

Similarly, an elegant WWII Yakovlev Yak-3 fighter of Soviet make can be found nearby in the colors of Yugoslavia.

After the end of WWII, Tito was determined not to surrender his political and economic independence to Stalin. In this high-stake gamble, he made no secret of his thoughts, and sought international recognition from the west. As expected, Stalin showed no sense of humor in that matter, and as the USSR broke relationships with Yugoslavia, this country faced the risk of isolation and of Soviet invasion in the early stage of the Cold War (late 1940s).

Over the years, the good relationship established with the western Allies during WWII were strengthened further, and most incredibly for a communist country, the US provided aircraft and helicopters, in the form of Republic P-47 Thunderbolt, Lockheed T-33 Shooting Star, Republic F-84G Thunderjet and (much later, in the early 1960s) North American F-86D ‘long-nosed’ Sabre.

The years of Kennedy administration saw a significant improvement of the relationship between Tito and Khrushchev, and this led to a switch to Soviet aircraft in the form of the supersonic MiG-21, which equipped the Yugoslav air force in substantial numbers over the following two decades. An exemplar of this iconic and ubiquitous aircraft, an unquestionably well-performing aircraft in his age, is preserved in the museum. By the way, the early 1960s saw also the widespread adoption of SOKO Galeb trainers and the phase out of older British/US models.

Other peculiar exhibits in the indoor part of the museum are the wrecks resulting from air fight operations during the Yugoslavian wars of the 1990s. On the national (Yugoslav) side, the tail cone of a SOKO G-4 Super Galeb – a totally different design from the quasi-homonym G-2 – damaged by a shoulder-launched Stinger missile in 1991.

But much more material is from NATO countries, resulting from combat during operation ‘Allied Force’ against Serbia in 1999. Most notably, you can see a substantial part of the wing of a Lockheed F-117 Nighthawk, the famous stealth aircraft downed by a vintage Soviet SA-3 Goa surface-to-air missile in March 1999, as well as a landing gear, ejection seat, pilot’s helmet, Vulcan cannon and some smaller parts of a General Dynamics F-16 Fighting Falcon downed the following May, again due to an SA-3 missile. The first stage of the missile which hit the Nighthawk is on display too.

These are basically the only aircraft lost in action over enemy territory during that operation.

An apparently easier prey, General Atomics RQ-1 Predator UAVs were used in great numbers, some twenty of them being downed. One wrecked example is put on display.

More items of the kind include parts of NATO missiles, including HARM anti-radiation missiles and cluster-bombs containers.

On the upper level, you can find a mostly photographic exhibition mainly about the national carrier JAT. Interestingly, not a single Soviet-made model appears in the pictures, whereas you can find Boeing 707s, 727s, 737s, Douglas DC-9s, McDonnell-Douglas DC-10s, Aerospatiale Caravelles and ATR-42/72s – clearly a strong commercial bound with the West, pretty unusual for a communist country!

Another Yugoslav airline started operations to a later date – Aviogenex. This apparently did use aircraft from the USSR, in particular Tupolev Tu-134s, later flanked by Boeing 737s. Aviogenex ceased operations much later than the end of Yugoslavia, and operated as a Serbian company for some years.

One of the most iconic brutalist monstrosities in northern Belgrade is the skyscraper which used to host the headquarters of this airline – it looks like a good setting for some ‘Blade Runner’ or ‘Judge Dredd’ movie…

Some more panels include descriptions of airport history and modern operations in the nearby airport of Belgrade. The history line of the national aviation industry is also presented in detail through historical pictures.

Some more aircraft can be found on this level, as well as a SA-3 Goa missile in a non-operative paint scheme, likely for training or telemetry tuning purposes.

Outdoor exhibition

The large area around the building is split between a small outdoor exhibition prepared for the public, and a larger storage area with many more aircraft which can not be neared nor walked around.

The displayed aircraft include an Aerospatiale Caravelle in the colors of JAT. This exemplar was one of three operated by this airline, and was active between 1963 and 1976.

A much elder transport, a German (French license-built) Junkers 52 with P&W engines represents a fleet of four such aircraft operated by the Yugoslav air force, complementing another group of originally German aircraft captured during the war.

An aircraft of historical significance is an Ilyushin Il-14 twin-prop transport. This aircraft was a personal goodwill gift from Khrushchev to marshal Tito, and the founding member of Yugoslav presidential fleet.

A couple of Lisunov Li-2 and some original Douglas C-47 Skytrain, of which the former is a license-built Soviet version, are on display, albeit not all complete. A MiG-21 Fishbed and a Kamov twin-rotor helicopter are also on display.

Another extremely rare item from the post-WWII years, a Short SA.6 Sealand amphibious aircraft of British make has made its way to Belgrade, after years as a transport aircraft in the Yugoslav air force.

The non-visible part of the museum features a rather impressive collection of MiG-21 in several versions, SOKO J-21 Jastreb and SOKO J-20 Kraguj in a large number, a SA-2 Guideline soviet-made SAM launcher with two missiles, and a number of partly assembled aircraft and wrecks.

A mystery item is a part of an allegedly US aircraft, apparently a part of the tail empennage of a bigger transport – any suggestion about this item welcome!

Visiting

The museum is located to the northwest of the airport of Belgrade. It can be easily reached by car from the access road going to the main terminal area. Website with info in English here. Parking ahead of the entrance.

The museum can be visited in about 2 hours by an interested subject, much less if you have just a mild interest in aviation. Much paneling is in double Serbian and English language, allowing to get the most from your visit.

Despite being fully operative, the place has a somewhat rotting appearance especially from the outside, as mostly typical to former state-run institutions in former Yugoslavia. Furthermore, some form of protection for the aircraft in the outside exhibition is hopefully to be considered by the management, otherwise the aircraft with literally disintegrate to the action of the elements in a matter of some years.

Soviet and East German Relics North of Berlin

For the full span of the Cold War, the communist German Democratic Republic has been a highly militarized region.

Due to its position right on the European border between NATO countries and the USSR-led eastern bloc, this relatively small state was kept in high consideration by the Soviet military staff in Moscow. In the re-organization of Soviet forces following the end of the Great Patriotic War (i.e. WWII), of the four Soviet groups of forces stationed in all satellite countries outside the Soviet border, one was specifically named ‘Group of Soviet Forces in Germany’. This group was headquartered in Wünsdorf, the former location of the German OKW south of Berlin (see this post), and had under its command a force of some hundred thousands troops, divided in two tank armies, an entire air army, three mixed armies and a supplementary artillery division. Supplies were in no shortage either, with some tens of fully operational airbases/tank polygons, academies and housing for all the troops and respective families.

Despite the very significant Soviet presence, the GDR invested a huge capital of its own in the development of a full-scale military strength. The East-German National People’s Army (NVA) received top-tier technology from the USSR, and did of course manufacture military supply of all sorts. Sustaining this army, together with the enormous para-military organization of the internal Ministry of Security – the ill-famed STASI – and other governmental organizations, military expenses undoubtedly contributed to the economical crisis hitting the GDR in the 1980s, setting the scene for its final demise.

The region north of Berlin was particularly rich in military and governmental installations, some of them highly classified, their history shrouded into mystery. You can find some information in dedicated posts on this website (see this post, also here and here).

In this chapter, some more items of interest are featured. Four of them are abandoned tokens from Soviet occupation. A nice belle-epoque villa on the shore of the Röblingsee in Fürstenberg, where the headquarters of the 2nd Guard Tank Army was headquartered since Stalin’s era to the withdrawal of Soviet forces in the 1990s, is the first of them. The second is a unique, forgotten Soviet monument, to be found less than two miles south of Fürstenberg. Two more are memorials and cemeteries, for Soviet troops who perished in the last stage of the Great Patriotic War (WWII) around Berlin.

Other three points of interest are instead GDR-related. The first is the former academy for future leaders of the communist party, established in Wandlitz in the years of Stalin, and initially led by Erich Honecker, later to become the omnipotent leader of the GDR for two decades. In the same area north of Berlin – and precisely in Waldsiedlung, today a nice clinical campus in the countryside – are the former private houses of the members of the central committee of the communist party of the DDR – personalities like Walter Ulbricht, Erich Honecker, Erich Mielke and Egon Krenz lived here with their families. Finally, you will find a glimpse from the so-called ‘Honecker bunker’ in Prenden. This big and highly classified installation was prepared in case of war, to protect the leadership of the GDR and ensure safe communication with Moscow.

Photographs were taken in summer 2019 and 2021.

Soviet 2nd Guard Tank Army Headquarters, Fürstenberg/Havel

Among the Soviet forces permanently stationed in the GDR in case of war, there used to be two entire tank armies, the 1st and 2nd. The former was headquartered in Dresden, whereas the 2nd – named ‘Red Banner’ – in Fürstenberg/Havel.

The headquarter in Fürstenberg is basically an old villa, possibly dating to the late 19th century or a slightly more recent time. The villa is somewhat unusual in the panorama of todays Fürstenberg. This is a nice and lively touristic town, where many Berliners come to find a retreat in nature, less than 1 hour driving from home. Thanks to tourism-related activities, the area has got rid of the Soviet/East German grayness, and is now a typical village in the German countryside, graced with a creek and a small lake, where canoes and small boats are always roaming around.

In stark contrast with this, the villa is today completely abandoned, with overgrown vegetation almost hiding it from the main road. Access to the premises is easier from the back, where you first meet a typical Soviet prefabricated wall, and service buildings with evidence of a communist design – the usual yellow paint and railings on the windows with the stylized ‘radiant dawn of communist revolution’.

Getting closer to the house, you meet an access door, possibly going to a bunkerized area underneath. The house is in a really bad shape, with rotting walls, plants growing on the balconies and roof. The inside has been made completely inaccessible. A typical East German light is still hanging from the back wall.

To the front, a temple-like decoration contours the main door. It is difficult to say whether this decoration was there since the beginning, since it appears rather different in style from the rest of the villa.

A highlight of this site is the statue of Lenin still standing ahead of the front facade. The statue is in a relatively good shape. It looks like the man was portrayed during a discussion.

The concrete sculpture was accurately made, as witnessed by the facial expression and details in the embroidery of the tie.

On the front side, the villa used to be reachable with a large flight of steps climbing uphill, with Lenin on top. Today this perspective is gone, for vegetation has totally invaded the steps, and the front of the house is not visible from the street.

Getting there and moving around

The villa is located in central Fürstenberg on Steinförder Strasse (possibly) 44, on the southern side of the road. The house and its large garden estate are abandoned, but all other houses around are not. Getting closer without being spotted is easier from the backstreet. Technically speaking, the latter is accessible for residents only, so you may park somewhere else and come closer by foot. Visiting may take about 30 minutes with time for the pictures, for the house is not accessible inside.

It should be remarked that this site is probably not public, and at an unpredictable time it may be either restored or demolished – so checking it out may be not possible for long.

Soviet Monument, Fürstenberg/Havel

A rare example of Soviet commemoration monument can be found very close to Fürstenberg. Apart from the monumental sites in Berlin (see here), a number of smaller Soviet monuments are to be found around the GDR – impressive ghosts of a bygone era.

Among the best preserved are that in the former tank base of Zeithain (see this post), and this one in Fürstenberg.

The monument is composed of two parts, basically two concrete curtains facing each other on the sides of a small apron.

The smaller panel to the south is the most intriguing. It is apparently a celebration of an economic plan of the Soviet Union. It is all about the growth in production in several areas of industry and farming, likely resulting from careful planning by the top of the Soviet government.

Between a citation from Lenin and a stylized image of the Kremlin, several panels cite one by one the increases in production of anything from oil to weapons, from milk to corn.

To the back of the monument, the only remaining feature is a remarkable head of Lenin, with yet another citation. It is likely that other features have been removed by vandals, as empty frames can be seen aligned along this face of the monument.

The larger panel to the north is a celebration of the march to Berlin during the Great Patriotic War, likely related to specific actions of the Guard Tank Armies. The central slab features an image of the Soviet monument in Treptower Park, Berlin – one the most famous commemorative monuments in the Soviet Union, as witnessed by numerous images to be found still today in many museums in the former USSR (see for instance here).

Close by, reproductions of decorations and captions of what happened on some days of 1944 and 1945 are reported.

On the left panel you can see a reproduction of the march to Berlin, from the battlegrounds in the USSR, through central Europe and Germany. It is likely that some metal parts of the monument once used to connect the ‘points of interest’, but these have disappeared due to vandalism.

On the right wing of the monument the names of Heroes of the Soviet Union possibly from the Guard Tank Armies are cited one by one. Close by, the image of the ‘Soviet Motherland Calling’, pretty usual in Soviet war iconography, can be found together with other typical emblems.

Getting there and moving around

This monument is not maintained nor protected. It is open air, unfenced and freely accessible. It will be hopefully restored or moved to a museum, as the weather and vandals are taking their tolls. It can be reached along the road 96 about 1 mile south of Fürstenberg, immediately to the west of the road. A small unofficial parking area can be found ahead of it, making a quick visit really easy.

Soviet Memorial and Cemetery, Rathenow

The Soviet memorial in Rathenow is one of a number of smaller military cemeteries for Soviet troops in the region around Berlin. Soviet soldiers perished in the area in the thousands in the final stage of WWII (1945), when the Red Army entered the northeastern part of todays Germany from Poland, pushing towards Berlin and fighting against the agonizing but still fierce German Wehrmacht.

Apart from the gigantic and formal monuments in Berlin (see this chapter), more modest shrines are scattered around the German capital city, all built roughly in the same period, between the end of the war in Europe and 1950, in the years of Stalin.

The Rathenow site is a small town cemetery, a proportionate, down-scaled version of its larger counterparts in Berlin – especially Schönholzer Heide (see here) – and can be found in the center of the sleepy town of Rathenow. A central obelisk with a commemoration plaque is topped by a golden five-pointed star, the symbol of the Red Army.

A number of soberly designed grave stones for as many Soviet troops are aligned in rows, creating an elegant perspective. Most of the graves bear complete names, as well as the birth and death years. Similar to the war cemeteries dating also from WWI (see for instance here and here), the very young age of most of the troops in the final struggle around Berlin is readily apparent.

Despite being fenced and of course not left in a state of disrepair, the green areas immediately outside of the perimeter of the monument in Rathenow are somewhat neglected, perhaps reflecting a fading interest for this monument.

Getting there and moving around

The Soviet monument in Rathenow can be reached at the crossing of Ferdinand Lassalle Str. with Friedrich Ebert Ring, in central Rathenow. The monument is very compact and can be toured in a few minutes.

Soviet Memorial and Cemetery, Blumberg

A Travel Guide to COLD WAR SITES in EAST GERMANY

The monument in Blumberg, in the northern outskirts of Berlin and really close to town, is smaller than the one in Rathenow (see above), but shares the general arrangement with it.

A central pillar with a commemoration slab is surmounted in this case by a statue of a Soviet soldier, holding a Red Banner flag.

Ahead and around the pillar, gravestones put flat on the ground are aligned in a perspective. However, the overgrown vegetation is basically hiding these lines of tombs, so that even from a small distance the central monument appears as an isolated item, put in the middle of a grassy area.

Actually, the major difference with other monuments of the kind lies in the rather remoteness of the one in Blumberg. It is a listed historical landmark, and therefore at least minimally cared for, but on the other hand, it is located relatively far from todays nearest settlement, hidden in the trees, and out of sight for anybody except people going there specifically for it. This makes it rather mysterious, a silent memento of old memories.

Getting there and moving around

The monument is conveniently located just out of the A10 highway (the external ring of Berlin), in the settlement of Ahrensfelde. You may reach Chausseedreieck and drive to its western dead end, where you can conveniently park. From there a grassy path points south into the trees, and in less than 150 yards you will find the monument. The size of the monument is small, hence no further walking is needed. A mosquito repellent is highly recommended in the warm season.

Free German Youth Academy & Joseph Goebbels Manor, Wandlitz

Deep in the countryside about 25 miles north of Berlin, about 3 miles from the small touristic village of Wandlitz, you can find a couple of highlights from the troublesome past of Germany, sitting side by side, close to the small Bogensee lake.

The first is the country estate of Joseph Goebbels, the famous minister for education and propaganda in the years of the Nazi dictatorship. This villa has been built in the war years, and often used by its owner, also for receiving guests. Goebbels obtained the estate as a birthday present from the Nazi Party.

Incredibly, the manor, built in a typical German country style, was not demolished after the war – so unlike other residences belonging to Hitler or his fellows, it is still there to see. It survived denazification, Soviet occupation and 40 years in the GDR as part of a school (see below).

The outside is the only part you can see. The appearance is sober, with simple lines and not much vertical elevation – it nicely integrates in the natural setting.

Access to the courtyard is from a small road, now part of the inner network of the larger complex surrounding the manor.

This complex is actually the other peculiar item you can find in Wandlitz. This enormous academy was built in 1951, on behalf of the Free German Youth (FDJ), a youth-training organization founded and originally run by Erich Honecker, later to become the general secretary of the communist party of the GDR in the 1970s and 1980s.

The academy was designed by Hermann Henselmann the same architect who designed Karl-Marx-Allee in the Soviet sector of Berlin – one of the most iconic ‘Stalin’s-style’ perspectives in the world. The complex is composed of two large opposing buildings, on the short sides of an internal courtyard. These hosted common areas, lecture rooms and a theater.

Along the longer sides of the courtyard are buildings with bedrooms and services for around 500 students.

The academy was for the future staff of the communist party, and in later years of the Cold War it was attended also by international students from communism-leaning nations, or sometimes even from NATO countries.

Following the collapse of the GDR, the building went on hosting educational institutions until the early 2000s, owned by the regional government. It was then mostly shut off, with some ancillary buildings still hosting institutions connected with the administration of the natural preserve around. It was put up for sale, for a while, but all potential customers failed to present satisfactory conversion plans. An expensive and inconvenient ghost from a forgotten era, as of 2019 its fate has not been sealed yet.

Today the place is not completely abandoned. Basic preservation works are being carried out, thus avoiding the roof to collapse or the walls to rotten. The names of the blocks are likely not from the GDR years. Similarly, a board with notices and maps dating from later than 1989 can still be seen, a witness of the post-GDR activity.

The garden is not growing totally wild, and some architectural addition must have been tried in a recent past – like a small modern fountain ahead of the common building to the southwest of the complex. The buildings are still supplied with electrical power – there are lit lights above some doors – and it is discretely guarded to avoid vandalism.

Getting there and moving around

Accessing the area is possible following the L29 from Wandlitz. About 1 mile from the village, the road changes its name to Wandlitzer Strasse. There is a local road with limited access taking to the east. You may park there, and proceed along the road by foot for about .5 miles to reach the heart of the complex. This is surrounded by private houses. There is no fence, but there are proximity sensors which trigger an inspection. I was reached by a warden on a car soon after my arrival. He spotted me, but did not come close, likely noticing I was just taking pictures outside.

The site is rather mysterious and well worth a quick visit for interested subjects. Touring the site will not take more than 45 minutes, taking all the pictures.

Private Homes of the Members of the Central Committee of the Communist Party of the GDR, Waldsiedlung

Similar to other top-ranking figures in the Soviet chain of command – like Stalin and others in his communist entourage, who did not spend much of their time in public or close to crowded places in central Moscow – the masters of the communist party in the GDR had their homes in the trees north of Berlin, relatively far from the city center and from the governmental buildings.

Actually, many of them lived together in a rather compact residential district, called Waldsiedlung. Access to the area was obviously controlled, but once inside the place was somewhat similar to a holiday settlement, with smaller single or two-family houses located along quiet alleys in a rural setting. The architecture is far from lavish – all houses are very similar to one another, and are designed in a plain typically East-German style from the post-WWII era.

Today, the settlement in Waldsiedlung has been converted into a campus for clinical studies. However, the original architecture of the place has been left mostly untouched, and explanatory panels telling quick information about the history of the residence have been planted ahead of most of the housing once occupied by old communist big brasses.

The office by the gate, and the metal gate itself, are totally original, as can be seen from historical pictures.

Among the first buildings past the gate is a former congress center/clubhouse/gathering facility for the inhabitants of the residence.

Moving on to the northern part of the settlement, the modest house of Erich Honecker and his wife Margot can be easily found. The two-storey construction has a patio on the backyard. A mystery wooden hut can be found next to the latter.

The Honeckers were forced to leave this house in the turmoil following the collapse of the wall and the starting of the reunification process. Honecker fled to the Soviet Union in seek for protection, quickly departing from the Soviet base in Sperenberg (see here). He was trialed in absentia, in connection to the order issued to the GDR border guards to used deadly force against people trying to pass the ‘anti-fascist wall’, and the ensuing deaths. He remained in the USSR until also that dictatorship collapsed, and he was forced to escape to South America, where he died soon after.

To the far end of the same alley is the house of Walter Ulbricht and his wife Lotte. Somewhat larger than Honecker’s house, it is however not much more evolved in adornments or architectural fantasy.

On another alley, parallel to the previous one, is also the house of Erich Mielke, the uncontested head of the ill-famed STASI, since its early years to the end.

The man was captured and trialed for an old case of homicide, after the shut-off of the STASI monstrous machine. He died soon after.

Today even these smaller buildings have been converted for a new function in the clinical campus. Therefore, they cannot be toured inside. However, strolling in this inconspicuous, quiet village where a huge concentration of power used to be seated, provides a strange feeling.

Getting there and moving around

The Brandenburg Clinic, which has now taken over the Waldsiedlung residence for the members of the GDR government, is on the road N.273, between Bernau and Wandlitz. The clinic in Waldsiedlung is rather busy, and the parking ahead of it may be crowded. However, since the place is guarded and access regulated, that is the only credible parking option also for a historically-themed visit. You can access the area by foot undisturbed, and take photographs of the exteriors. There are explanatory panels ahead of many of the former residential homes.

Honecker Bunker, Prenden

Geographically very close to the academy in Wandlitz (see above) – less than 1 straight mile away – the bunker in Prenden is the central piece of a network of bunkers and military hardware, designed an built on behalf of the National Defense Council (NVR) of the GDR from 1973 onward, and named ‘komplex 5000’. The purpose was protection of the leadership of the GDR in case of a crisis or attack from the West.

The bunker is Prenden, technically listed as ’17/5001′, was a control center of incredible sophistication, designed to withstand nuclear blasts, and with direct communication with other sub-nodes of a larger communication network, thus granting safe communication and broadcasting ability, allowing to lead the country in case of a crisis. The bunker was intended to host the general secretary of the communist party, i.e. Erich Honecker, when the bunker was commissioned in 1983 – hence the unofficial name ‘Honecker bunker’.

The premises of Prenden are now largely in private hands, but some parts are apparently publicly accessible – the original fence has been completely torn down. The bunker itself is sealed, and can be accessed only on a few days per year with a guide.

The official entrance to the area is through the original GDR-made gate. This is closed however, for it is now the entrance to a small private industrial complex.

Traces of the original fence, as well as piping and vents for underground rooms, can be found around the hill on top of which the installation is standing.

Some service buildings in typical communist style can be still found, despite demolition works having taken place. Proximity sensors and signs delimit the private property area.

The three-storey building on the southwestern corner of the complex used to be the ‘front office’ of the bunker. Today, it is in a really bad shape.

Inside, traces of the original furniture and services can still be found, albeit much deteriorated.

Access to the bunker is on the underground floor. You may notice the prison-like railings ahead of the access stairs. A feature that might make you jump when you are exploring alone – if walking in a forgotten communist government building, deep in the silent German countryside, was not enough… – is the lit bulb hanging over the entrance to the bunker – really unexpected!

Besides the building, a shelter-garage for trucks and cars is still in a relatively good shape.

Getting there and moving around

The Prenden bunker is not publicized, but it can be neared easily with a car, about 1 mile south of the small village of Prenden, along Utzdorfer Strasse. The gate can be clearly spotted, but it will be likely closed, and there are obvious ‘no trespassing’ signs and labels of private companies. You may park outside and proceed along the side of the property to the back of it, where the abandoned building mentioned above can be found. Whether this is still on private land or not is not very clear. There are proximity sensors between the abandoned building and the rest of the complex, likely to trigger inspection if you get too close to the (surely) private part of the complex.

Venturing in the building is definitely not safe, and the bunker entrance is usually closed. Official visits to the bunker are possible on guided tours arranged irregularly about once per month (please browse the internet for more info on visiting, cause I could not find an official site of the place to link here).

Cold War Forts and Museums in Denmark

During the Cold War the condition of Denmark on the international stage was among the most complex. Coming from years of neutrality before WWII, conquered in a matter of days in spring 1940 by neighbor Germany, at that time in the throes of the Nazi fury, it found itself on the front line of the two opposing blocs soon after May 1945.

Having not been occupied by the Soviets during WWII, it could better choose about its future, and in 1949 the mother country of the Vikings joined NATO as a funding member – unlike neighbor Sweden and Finland – thus giving its availability to its Allies to help countering Soviet influence over the territory under its control.

History in brief

Often overlooked when looking at the world map for its relatively small area, at the beginning of the Cold War the geographical position of Denmark nonetheless was – and, to some extent, still is – strategically very relevant. It is right on the inlet of the Baltic Sea, with a proximity to the foreign coasts of Norway and Sweden such to allow easily blocking the marine traffic on the Kattegat strait, when needed, by means of mere cannon fire from the coast. During the Cold War, this meant a virtual control over a sea where the USSR and Eastern Bloc Countries had many industrially relevant and non-freezing ports, as well as navy bases. Furthermore, the islands of Denmark, where large cities like Odense and Copenhagen are, can be found as close as 1.5 hours by boat to the coast of the German Democratic Republic – once one of the most heavily militarized countries on earth, also thanks to a massive Soviet presence. The smaller island of Bornholm, further east, is even closer than that to the coast of Poland.

A curious fact in history demonstrated the proximity of Denmark to the communist sphere of influence, shaking the minds of top ranking Soviet military. On March 5th, 1953, on the very same day of Stalin’s death, the first defection of a jet fighter from the Eastern Bloc took place, when a Polish MiG-15 on a routine flight along the Baltic Coast suddenly left his mates and rushed to Bornholm, where it landed on a field, leaving the aircraft in almost pristine conditions.

The cautious reaction of the Danish government and military forces reflects the position of the country at the time – they had identified the USSR and their satellites as a clear and present threat, and consequently they had taken the side of the West. Yet Denmark knew it could not withstand a direct military hit by the Soviets for more than a few hours, therefore as a form of self-protection, any form of provocation, at least in the early 1950s, was carefully avoided. While the pilot of the MiG was allowed to escape to the UK and then the US, the aircraft was quietly ceded to the US military for technical inspection in the FRG, but then re-mounted and returned to Poland. Other examples of a policy of constant detente with the Soviet Union are represented by the refusal to have NATO bases on its territory, or despite the adoption of the Nike missile system for the airspace protection, the missed deployment of the corresponding tactical nuclear warheads.

Of course, in recognition of the strategic relevance of this pleasant country, plans for a Soviet invasion which would strike in northern Europe, with the objective of reaching to the ports of the North Sea in less than a week from Eastern Germany, included as a major target the quick occupation of the Jutland peninsula, and of the islands of Denmark as well. This had to be done by marching fast through the northern regions of the Federal Republic of Germany, and simultaneously landing troops on the Danish islands.

About this post

Albeit not enough populated to sustain an army capable of resisting the eastern opponents on the other side of the Iron Curtain, thanks to its position on the map, Denmark took over seriously a fundamental border monitoring and interdiction task in favor of all NATO forces. Two tangible witnesses of this are the military bases of Stevnsfort and Langelandsfort, both located on the southern coasts of the islands, overlooking key sea straits, and pointing south to the East German coast. Both have been shut down after the end of the Cold War, and now they can be visited as top-tier military museums.

Further souvenirs from the Cold War era can be found in the Defense and Garrison Museum in Aalborg, a wide-spectrum military museum with a focus on WWII and the Cold War, and in the Danish Museum of Flight, where exemplars from the heterogeneous wings of the Danish Air Force are displayed, together with unique specimens of Danish aircraft production from the inter-war and early Cold War period.

This post covers all these four sites, visited in summer 2019. Presentation doesn’t follow any special order.

Cold War Museum Stevnsfort

This museum on the eastern coast of the island of Zealand (the same of Copenhagen) is actually a former Cold War military fort, operative from the early 1950s to the year 2000. It was re-opened as a museum in 2008, carefully preserved in most part in the forms it had in the 1980s, the most technologically advanced years of the Cold War.

By the entrance to the museum area you can see three surface-to-air missile, namely an old Nike-Ajax, and a much more performing – and bigger – Nike-Hercules. Both were part of the US Nike airspace protection system, which was deployed in Denmark around Copenhagen. The missiles are from the Cold War years, but were not originally present on Stevnsfort.

Strictly speaking, Stevnsfort is not the part of the installation you access first. The area you meet when getting in from the parking used to be a missile base in charge of the Danish Air Force. It was built for the Hawk system, another US interdiction surface-to-air missile system, the heir of the Nike system. Actually, Nike Hercules batteries in Denmark were withdrawn from use – as elsewhere, see this post – in the 1980s. Their role was taken over by Hawk missile batteries, gradually entering service since the 1960s, and operated till 2005 in Denmark.

Differently from its predecessor, the radar-based Hawk system was entirely movable, making it more flexible and less vulnerable. As a result, there are basically no bunkers in this area, and all constructions here are ‘soft’. Target designation and tracking was demanded to three sub-systems, namely a radar-pulse antenna for target individuation, an interrogation friend-or-foe (IFF) and a target-tracking/homing antenna.

Two radar-pulse antennas are displayed. The aerial emerges from a tent, which covers the electronics and motor of the system. Both are mounted on a truck trailer, which is actually totally movable. The range of the radar scanner was about 75 miles.

The IFF antenna is a smaller barrel-shaped device coupled with systems on-board aircraft, needed to distinguish between an enemy aircraft and a friend or ally. The target-tracking/homing antenna, with its distinctive two radar dishes, shares the installation setup with radar-pulse antennas – it sits on top of a trailer, covered in a green tent.

Close by, trucks and special moving cranes to mount the missiles on their launch gantries are displayed. Also containers for the missiles are shown, together with an example of the Hawk missile itself. The launch order could arrive only from the central Air Force command, except in case of a communication breakdown, when each missile base could decide on its own – at the high risk of making a mistake!

Farther on, power trucks and other launch systems are displayed besides batteries of Hawk missiles. The launch gantry is smaller in size compared to that of Nike-Hercules, but each gantry launches three missiles instead of only one. The gantry is anchored to the ground, and when inactive it is shrouded in a peculiar rubber-coated eyelid-like bubble, which can be quickly lowered to let the missiles out.

On the far end of the missile area, you can see an old-fashioned coastal cannon, part of the original fort, used as an illumination cannon in support of larger cannons in the battery.

One of the naval gun batteries is the first item you meet when entering the actual Stevnsfort fort. The fort was built between 1952 and 1955 for use by the Navy, and is the oldest part of the installation. Together with the Langelandsfort gun battery and command post (see below), it was tasked with monitoring marine traffic along the straits giving access to the Kattegat and the North Sea from the inner Baltic. For the purpose, it was supplied with a huge underground bunker, its most distinctive feature, as well as batteries of naval guns.

The 150 mm guns have an intriguing history. They were made in Nazi Germany early during WWII, for the Kriegsmarine ship ‘Gneisenau’. This was damaged when still in the dockyard, and the guns were re-designated to be placed on the Danish island of Fano on the North Sea coast, as part of the fortifications of the Atlantic Wall. Following the end of WWII in May 1945, the guns were captured and finally found their way to Stevnsfort.

The two-guns batteries were capable of 4-6 shells per minute per barrel, and could reach to the coast of Sweden, thus effectively closing the Oresund strait between Denmark and Sweden if needed. While primarily an anti-ship battery, the swiveling turret could be used to cover the coast, in case of an amphibious attack.

Firing direction was by means of a primary radar station on site, which is still in use, complemented by five other stations along the coast. The shells were loaded with an elevator from the bunker underneath. The guns were temporarily deactivated – but not dismantled – in the 1980s, when Stevnsfort assumed the role of main control and communication post for the southern district of the Danish Navy. Joint exercises with the military forces of the FRG were carried out also here in the final years of the Cold War.

By the entrance to the underground bunker you can spot several air hatches emerging from the ground, and an example of sea mine. The latter was the primary weapon to interdict traffic on the strait, with gun battery fire being mainly directed against enemy mine-sweepers.

Past the entrance, you need to descend a long stair into the bunker. At the base of the stair is an airlock with facilities for decontamination. The Stevnsfort bunker was most notably the first structure in Denmark to be built to withstand a nuclear attack.

The bunker is not excessively big, with about twenty reinforced-concrete-padded rooms connected by tunnels carved in the rock.

One of the highlights of this installation is the communication bunker, operative since 1984 in an area formerly hosting a hospital, then shut down when the naval batteries were deactivated. This used to be a highly inaccessible facility during the Cold War. Thanks to a careful preservation, the room looks like it was still in use! Batteries of telex and other communication machines originally in place, monitors and modern imaging technology from the Eighties, together with examples of ciphered messages are all on display.

Next to the communication room, the operation room is even more impressive. Similar to the former, it was constantly manned, and totally inaccessible for non-authorized personnel. The radar monitors can be seen towering over the consoles! Military staff on duty identified and followed all marine traffic in the assigned district, both civilian and military, friends and potential enemies.

Catalogs of existing ships are on display. Several thousands ships were identified and observed from this facility in the days of operation. It is reported that patrol ships from the USSR approached the coast under surveillance about 30 times per year, tasked with familiarizing troops with local geography…

Another highlight of the visit is the ammo storage for the gun battery previously visited. In the storage, explosive cartridges are placed separately from the shells themselves. There were four types of shells, recognized through a color code – grey for armor-piercing, orange for explosive, green for illuminating and blue for inert.

The almost-100 pounds cartridges were loaded on an elevator, and lifted up to the battery. A ladder provided direct access from the bunker to the cannons, serving also as an emergency exit.

Other rooms you can visit are sleeping quarters for the 250 men which stationed inside the bunker, until the guns were deactivated in 1981. The fort was capable of sustaining prolonged isolation in case of crisis or war. During the Cuban missile crisis, the Stevnsfort bunker was put on maximum alert for a week, with all men living underground, all accesses sealed.

Getting there and moving around

The Cold War Museum Stevnsfort is an international-level museum, to be found 1 hour driving south of central Copenhagen. The official website with directions and opening times is here. Visiting inside the gun battery and the bunker is possible only on a guided tour, where you are given an audio guide in English (also German and possibly other languages) if you can’t follow the Danish-speaking human guide. The guided tour includes also a visit of the missile battery, but this part can be toured also on your own. The guided visit lasts about 1.5 hours, and may turn a little boring in some parts (as usual, the human guide speaks longer than your audio-guide), but it is needed to get access to the most unique parts of the museum. I suggest visiting relatively early in the day, allowing some spare time after the guided tour and before closure to tour the missile part on your own. Free parking ahead of the installation, nice military-themed shop.

Cold War Museum Langelandsfort

This museum has been opened on the premises of a former naval gun installation from the same years of Stevnsfort (see above). Located on the southern island of Langeland, at the inlet of the Belt channel giving access to the Kattegat from the Baltic, it was in a good position to monitor all marine traffic in its sector, as well as for blocking the channel. As a matter of fact, similarly to Stevnsfort, the main target of the naval guns here were minesweepers, for the channel was completely covered with Danish remotely-controlled sea mines, and action of enemy minesweepers would have been necessary before any attack by the bulk of navy forces.

The main naval force in Langelandsfort was constituted of four naval guns, mounted on swiveling turrets, and a fire control bunker which in non-crisis time was used to keep trace of all marine traffic in the sector. The fort was complemented with anti-aircraft defensive positions, a bunkerized power station, and ‘softer buildings’, including barracks. Except for the latter, everything has been restored and can be visited. One of the naval batteries has been restored completely to its original form including the mechanisms underneath, whereas at the base of the other three batteries you can find exhibitions about various aspects of the Cold War – they are all pretty well studied, rich and interesting.

The command bunker is the first construction you meet. The building is from the 1950s, and it shares many aspects with Stevnsfort, though this is much smaller. You can see sleeping quarters and a kitchen, which would be used especially in case the fort was sealed, i.e. in case of high alert or war.

The control rooms are three. Two are for tracking marine traffic in the marine district of the Belt, and also for coordinating air operations from other military installations in Denmark. A radar antenna and an observation tower outside, likely complemented by similar gear in the area, provided a complete real-time picture of the civilian and military traffic in the sector. It is reported that ships going to Cuba with SS-4 nuclear missiles and related supplies were spotted in these rooms months before that material was photographed by the US, when the crisis broke out.

The third control room is the fire control room for the whole fort, coordinating fire from all four gun batteries. Fire control was by means of a very interesting piece of machinery, a fully mechanical computer, taking in atmospheric data like temperature, humidity, wind direction and speed, and target data. No electricity was needed except for lighting the goggles of this analog computer! A similar item was present in Stevnsfort, but I could not see it during my guided visit.

In an adjoining room you can see a perfectly restored communication facility, with ciphered messages hanging on the walls, as well as original transmission machines and early computers. There is also a personal study room for the commander of the post.

Besides the control bunker you can find an anti-aircraft position, centered on a four-barreled anti-aircraft gun. Similar to all others, the small bunker underneath could be manned and sealed in case of war.

The cannon battery closest to the control bunker has been restored completely, including the bunker underneath. The 150 mm guns, one per battery, were made in the final years of WWII by Skoda works in Plzen, in the then-Nazi occupied territory of Czechia. They were originally intended by the Wehrmacht for the Atlantic Wall in Denmark, but they never became operative there. Instead, they ended up to be installed by Denmark to counter a Soviet threat on the Baltic.

The mechanism for supplying cartridges to the cannon is similar to that in Stevnsfort, with an elevator lifting the explosive charge and the shell separately to the level of the gun. However, here the storage bunker is just beneath the cannon, and the lift does not carry the cartridge directly inside the turret, but to a hatch in the reinforced wall besides the cannon – something similar to some of the smaller cannon batteries of the Atlantic Wall built by the Germans.

Inside the bunker you can see the ammo storage, as well as a sleeping compartment for the 15-men crew needed to operate the cannon.

Some example shells have been preserved, with colors corresponding to different functions of the shell (see Stevnsfort above).

The cartridge elevator room is very small, and access is from both sides. Explosive and shell came from opposite directions, each from the corresponding storage room.

The bunker under the next cannon battery has been dedicated to the analysis of the threat from the Danish perspective. Here you see copies of the Soviet plans to invade Denmark, as part of an operation to conquer central and northern Europe lightning-fast in case of an open war against the West. Among the most striking items, you can see detailed Soviet maps covering all regions of Denmark – with city names and all writing in Cyrillic!

There is also a nice collection of ordinary weapons and military supply from the Eastern Bloc, and especially from the neighboring German Democratic Republic. A very special feature is an example of the ‘Blücher decoration for valor’, a medal created by the GDR to be attributed to individuals for actions of exceptional courage in the defense of the GDR, and to be assigned only in case of war – thanks to the Cold War never turning ‘hot’ for the GDR, nobody could be awarded this decoration.

The next battery is dedicated to espionage and spy gear, with many examples of James-Bond-like trinkets, actually used by both enemy and Danish spies. Machinery for ciphered communication, once considered hi-tech, is also on display, together with maps used by a Danish spy visiting the Polish coast, and satellite imagery of East German/Soviet airbases.

The exhibition in the last battery is about the Cold War and society, and is full of old photographs of pro-Soviet protesters in Denmark, spies, famous characters of the Cold War, momentous events taking place in Denmark during the Cold War and so on. Most notably, there are also many artifacts from both Denmark, the Eastern Bloc and the USSR, including medals, posters, portraits and much more.

Similar to the control bunker, the power station has been preserved in its original condition. Three diesel engines could provide power to all bunkers in case of war or failure of the grid for whatever reason. Immediately outside the entrance to the power station bunker there are apparently some suspended showers…

The large area of Langelandsfort has been selected also for the exhibition of a submarine, a mine-sweeper and two aircraft! The submarine ‘Springeren’ was used by Denmark in the 1990s and early 2000s, but it was built much earlier and operated by the Norwegian Navy. Sadly, after the retirement of ‘Springeren’, the Danish Navy shut off completely its underwater branch. The ship is a small conventionally powered attack submarine. The interior is apparently pretty modern with respect to older German or US WWII U-boats.

The submarine features six torpedo tubes.

The mine-sweeper has the appearance of a small conventional boat, but with room for a crew of several men. It is hosted in a hangar together with examples of sea mines – apparently US models.

The two aircraft are a SAAB Draken of Denmark and a MiG-23 of Poland. They represent some of the most advanced aircraft of these opposing countries at the height of the Cold War. Both exemplars are well preserved inside hangars protecting them from the weather and sunlight.

Another interesting sight is a reconstruction of a civil defense bunker, with much original material, including packs of ration cards already prepared for the population in case of war. In an adjoining room you can see a reconstruction of a bunkerized broadcasting studio – the national TV channels were tasked with providing updates to the population in case of an attack, hence a similar facility was prepared in the basement of the TV headquarters.

Close to the ticket office, you are offered a very well-designed exhibition tracing the timeline of the Cold War, with some clever text and many pictures, some of which rather uncommon – really worth spending some time on, before or after visiting the museum.

There is also room for temporary exhibitions, in a hangar which includes an original section of the Berlin Wall.

The building of the ticket office is also interesting. From the back of it you can get access to a smaller exhibition about travels to the DDR (the native acronym for the GDR), with everyday items, old Interflug boarding passes, and some incredible postcards – apparently, modern Soviet-style housing and heads of Marx were the items that GDR postcard-designers liked most… Fragments of the Berlin Wall are also on display.

Ahead of the entrance there is an old and pretty big hammer and sickle, originally from a Soviet ship. The commander threw it outboard when the Soviet Union officially ceased to exist. It was collected by a Danish sailor and ended up here. Nearby you can see a reconstruction of the Berlin Wall, and an original Trabant crossing it.

Getting there and moving around

The Cold War Museum Langelandsfort is located close to the southern tip of the island of Langeland, which is connected with bridges to the major island of Fyn, where Odense can be found about 1-hour north of the museum by car. You can move around the museum on your own, there are several panels with explanations. Most panels have at least a quick translation in German and English. All presentations are very well designed and maintained. Visiting may take at least 2 hours for an interested subject, and even more especially if you are taking pictures. Free parking ahead of the entrance, and picnic area nearby. Official website here.

Aalborg Defense and Garrison Museum

This museum was opened in the year 2002, in the hangar of a seaplane base constituted by the occupying German forces in 1940. The base was potentiated in more instances during WWII, and a half-interred command bunker similar to those of the Atlantic Wall was added.

Aalborg has been a military post for centuries, therefore the museum is centered on several aspects of war and military life. Of course, the majority of the artifacts on display date from WWII and the Cold War period.

The hangar hosts a small collection of aircraft, which capture your sight when you get in. Most notably, there are a venerable F-84, an F-86, and somewhat older T-33 and Gloster Meteor.

Close by, you can find a more modern F-104. Jet engines of American make from some of these aircraft have been taken out of the airframes, and put on display separately.

Again in the center of the hangar you can see a Hawk missile system, including the missile battery and movable power and control trucks. Also anti-aircraft guns and searchlights from various ages are on display.

Items from WWII include a nice exhibition of locally-collected gear used by the Danish resistance movements. Supplied by the Allies from the air, they managed to build several types of bombs, mines, and so on, made to disturb and damage enemy transports, or to kill enemy staff in well programmed para-military actions.

Memorabilia include the engine of an US B-17 bomber, sadly downed over the Baltic during the crew’s final mission, the original Luftwaffe eagle once standing on the building of the local German air command, and a Nazi flag weaving on some public building in town in the years of the German occupation.

There are also many photographs from the area from the war years, and reproductions of German maps and local newspapers. The latter tell about relevant facts taking place during the war, as reported by the local media. There are also diplomas of merit issued by the US and Britain in favor of a local citizen, member of the resistance.

A part of the exhibition is about civil defense. Similar to the US, Britain and other countries during the Cold War, this service was activated to prepare the population to a nuclear war scenario, and to provide shelter and a chance of survival, by means of bunkers and deposits of supplies. Here you can see a reconstruction of such a shelter, and items which used to be stored in preparation for survival in the nuclear winter.

There is also a nice collection of light weapons from local firms, uniforms and communication rigs.

A few uniforms and technical gear from the current supplies of the Danish military are on display as well.

In a room to the side of the central hall, you can find uniforms dating from WWII, including German stuff. The story of a Dane coming to the US and fighting for the US Army is also told in a corner, also through some memorabilia.

On an elevated platform you can find an exhibition about the Cold War. This is mostly made by panels retracing the history of that confrontation over the decades. Among the most peculiar items on display, a copy of the invasion plan studied by the Soviet in case of a sudden war with the West. That plan included the rapid conquer of Denmark, due to its strategically relevant position. A copy of a Soviet-made map of Aalborg in Russian, needed in case of war, is another example of the unique artifacts on display.

This special Cold War exhibition is completed with a set of field and anti-aircraft weapons from various ages of the confrontation.

Other rooms around the main hall display modern uniforms, NATO-related material, military supply from various ages and even a throne used by the Queen of Denmark on an official visit.

In an adjoining smaller hangar you can find a rich collection of trucks and weapons with various – not only military – functions.

Outside, a highlight of the museum is the former air command bunker built by the Germans. This has been filled with memorabilia from the Nazi occupation period. An unusual and little-known story is told here, about the German refugees from Eastern Prussia, a region loosely coincident today with the part of Russia around the town of Kaliningrad (ex-Konigsberg). This area used to be part of Germany since before WWI, and it remained under the Weimar Republic, even though separated from German mainland. Neighboring Lithuania was annexed to the Third Reich before WWII – similar to Sudetenland – on account of the proximity to that region, with the excuse of a significant German group living in Lithuania. In 1939 the Germans re-gained control over northern Poland, and the two regions of Prussia were reunited in the Reich.

Following the victories of the Soviets in 1944 and the ensuing landslide-march towards Berlin, Eastern Prussia was lost to the enemy. Refugees escaped to mainland Germany, and the administration of the Reich sent these folks in several areas relatively far from the front – including a significant number to occupied Denmark, and especially in the hangars in Aalborg, where the museum is today. So the hangar acted as a hospitality center for the refugees. This was something strange though, for the refugees were not local nationals, but instead enemies. This led to a controversy soon after, when the war ended. In the event, most of the refugees returned to their land of origin, only to find it permanently occupied by the Soviets. Some handmade artifacts of these German refugees can be seen on display in the bunker.

Finally, a very good collection of tanks, field guns and movable howitzers from various countries including the Eastern Bloc and mainly from the various ages of the Cold War can be admired on the museum apron. For the most part, these are reportedly kept in working condition.

Getting there and moving around

The museum is located close to central Aalborg, on the waterfront. You can visit it totally on your own. Some of the exhibitions are described in more languages, but some parts are in Danish only. Nonetheless, the visit can be very rewarding for experts and for the kids as well, thanks to the chance to touch many of the artifacts on display. A two-hours time may be enough for having a look, more time is required for a more in-depth visit or if you want to take pictures.

Convenient parking just ahead of the entrance. Website with full information here.

Danish Museum of Flight

This fantastic collection of aircraft can be found next to Stauning Airport, on the west coast of Jutland, at the level of the Ringkobing firth. This is by far the largest aircraft collection in Denmark, and the reference air museum in this country.

The exhibition is well designed and rich, and it covers both the civil and military branches of aviation. Furthermore, a good half of the aircraft appear in fully airworthy conditions.

There are three thematic hangars. In the first you can find civilian aircraft from various ages, smaller sport aircraft and military trainers mainly from the inter-war period or the late 1940s. Some of them appear airworthy.

Most notably, there is the front part of the fuselage of a Douglas DC-7, formerly in service with the national carrier SAS, still on business today. The cockpit and the crew compartment are well preserved. The analog instrumentation adopted on this plane, which dates from 1957 and represents the last and most advanced of the Douglas propliners, is abundant and remarkably sophisticated.

Another unique aircraft on display is an Aerospatiale Corvette, an executive jet by the same French airframer who participated in the Concorde project. You can also board the plane.

Similarly rare today is the DeHavilland Dove, a British-made short range liner from the early Cold War period. Similar aircraft, cheap to operate, went on flying well into the 1970s in many countries. Here you see an exemplar in the colors of Cimber Air.

Among the trainers, you can find a DeHavilland Tiger Moth and a Chipmunk from the same manufacturer. Less common aircraft include a DeHavilland Hornet Moth, which apparently spent most of its flying time in Kuala Lumpur, and a nice Bucker Bestmann, a German trainer adopted and license-built also in Sweden.

Despite never adopted by the Danish military, a V-tailed Fouga Magister French trainer apparently found its way to here. It was reportedly flown in private hands by a Danish professor, before being donated to the museum.

In the first hangar are also examples of Danish aircraft production, including the reconstruction of an early prototype by a local pioneer. Propellers and dismounted engines and systems, likely used for training purposes in the past, are an interesting part of the exhibition too.

A huge collection of model engines, some air traffic control consoles and airport trucks complete the exhibition in the first hangar.

The second hangar is mainly devoted to aircraft manufactured in Denmark. Most notably, the Skandinavisk Aero Industri – abbreviated in SAI – specialized in trainers and small transport in the inter-war and WWII period, and knew a good national and local international success between 1937 and 1954, when it disappeared – and with it basically also the Danish aeronautical industry.

Some of the aircraft on display are unique exemplars, the last witnesses of this interesting story. Not all aircraft here are from this manufacturer though – an ubiquitous Piper Cub in its distinctive yellow colorway can be found as well, together with a Supermarine Spitfire. Also here, most aircraft appear to be in airworthy conditions.

In the last hangar, which despite being the largest one, is the most crumpled, you can find military aircraft retracing the history of the Danish Air Force supply. The aircraft here are all from the Cold War period, hence giving to this hangar a historical connotation. This part of the exhibition is also particularly nice, as you can walk close and beneath the aircraft, an ideal setting for getting pictures of smaller particular features.

The variety of present aircraft is very interesting, and reflects the close bounds of Denmark with the US and Britain. Aircraft from the early Cold War include Lockheed T-33, a North American F-86, and two different versions of the Republic F-84.

An exemplar of the latter is supplemented with JATO – Jet Assisted Take-Off – bottles under the fuselage. The mountings of the underwing rockets on the F-84 and of the belly rockets on the F-86 are really unique examples of Cold War technology!

A big Consolidated Catalina amphibious aircraft towers on all others in the hall, while a Douglas C-47 transport in excellent conditions is preserved in a corner, with an interesting ski system mounted on the landing gears.

British aircraft from the same early era include a Gloster Meteor and what appears to be a pretty rare Fairey Firefly. Another US design is a T-6 trainer, to be found under the wing of the Catalina.

More recent designs still from the Cold War include a Lockheed F-104, a British Hawker Hunter and a Swedish SAAB Draken.

Especially the configuration of the latter – both the general configuration and the arrangement of the landing gear and wing pylons – is really unique, reflecting a different yet interesting school of aircraft design.

Rather uncommon out of the US, a North American F-100 Super Sabre is also on display, with a foldable Pitot boom.

Finally there are a Hawk missile battery, a movable command center and service trucks.

Modern aircraft are represented here by an F-16. There are also two helicopters of US make, closing the collection.

Getting there and moving around

The museum is located between Stauning and Velling, two small villages on the inner coast of the Ringkobing firth, western Jutland. The facility is modern, with a large free parking and a picnic area. It is located on the border of a local airport, immersed in nature – a very pleasant location. The museum requires about 2 hours for an interested subject, 2.5 if you want to take pictures. Website with full information here.

Despite their great destructive potential and strategic relevance, nuclear assets were deployed far from the ‘centers of power’ in Moscow and Washington by both the USSR and the US. As the front of the Cold War was especially ‘hot’ along the border between the Warsaw Pact and NATO Countries in central Europe, large arsenals of nuclear weapons were deployed to the area, on both sides of the Iron Curtain, and in several instances over time.

On the western side this was not hidden and led often times to protests in Countries like the UK, West Germany and Italy, so that the history of the presence of a nuclear arsenal in those Countries can be traced with some accuracy, albeit not easily. Conversely, much less is known about the deployment of Soviet nuclear arsenals over the territory of the former Eastern Bloc, making this segment of Cold War history especially mysterious.

History – in brief

In this Cold War scenario, the German Democratic Republic (GDR, or DDR in German) received special consideration by the Soviets. Thanks to its advanced position in Europe and the local, much trusted ‘hardcore’ communist regime, the USSR planned the deployment of early strategic missiles – SS-3 Shyster and SS-4 Sandal – starting already in the late Fifties, the years of Khrushchev. Traces of an actual deployment exist in Vogelsang and Furstenberg, about one hour driving north of Berlin (see this post about Vogelsang, and this about the mysterious deployment of missiles in the area).

Later on, in the early years of Brezhnev as leader of the USSR, it was decided that for a prompter and more flexible response in case of an attack, nuclear warfare especially for tactical use should be deployed outside of the USSR borders, to Countries in close proximity with the West. On the other hand, strategic warheads and missile systems could be withdrawn to within the USSR, as more technologically advanced intercontinental ballistic missiles had become available, making a hit of a foreign objective possible even from deep inside the Soviet borders.

Consequently, deployment of air launched nuclear warfare started in selected Soviet airbases, which were really not in any shortage in the GDR – considering both the national air force (NVA) and the Soviet aviation, the DDR used to be one of the world’s top countries in terms of airbases per square mile, or per resident. You can see several posts on former Soviet bases in the GDR on this website (look here, here and here).

For military corps not operating from airbases – especially missile brigades – the headquarters of the Red Army in Moscow deemed necessary the deployment to the GDR of nuclear warheads for tactical or theater missiles.

Two depots were built anew in dedicated installations specifically for hosting such warheads. One was in Stolzenhain, codenamed ‘Objekt 4000’ and sometimes referred to as Linda (the name of a village nearby), close to the highly-militarized area of Juterbog (see this post) and Kloster Zinna, about one hour driving south of Berlin. The other was again close to Furstenberg, and named Lychen-2, and codenamed ‘Objekt 4001’.

The nuclear bunkers in Stolzenhain and Lychen were payed for by the GDR – through a governmental agreement with the USSR – which always detained official property of the facilities, and were built by German workers, around the year 1967. Once ready, in 1968 the bunkers were handed over to Soviet staff, and the corresponding areas totally closed to non-Soviets. The bunkers, as other similar facilities in other Countries of the Warsaw Pact, communicated directly with Moscow, as similarly to the US, only the top of the command chain could authorize the use of nuclear forces.

The facilities were kept running until the end of the Cold War. Control was officially given back to the agonizing GDR in 1990, the Soviets having transferred all valuable material to the (agonizing) USSR.

Here the story splits for the two installations. While the Lychen bunker has been selected for interment, the installation largely being demolished around 2015, forgotten and reclaimed by nature, as of 2019 the Stolzenhain bunker is in a far better condition, apparently in private hands, and albeit plans for it are sadly similar to Lychen, it may be still in time to be turned into a unique, world-class museum.

About this post

This post covers both Lychen-2 and Stolzenhain bunkers. The former was explored in the summer of 2019. The latter was explored a first time in 2019, and in a second instance with the guidance of its owner Manfred van Heerde and the nuclear scientist and historian Reiner Helling in 2021. As the Stolzenhain installation is still in a relatively good shape, you can also get an understanding of what the inside of these bunkers looks like, their design and specific features. Pictures of this installation from above can be found in another chapter (see here).

Objekt 4000 – Stolzenhain

The Stolzenhain bunker, aka ‘bunker Linda’, due to the name of a nearby village, is a perfect specimen of this type of construction (codenamed Monolith-type – see also this post for similar sites in nearby Poland, including one open as a museum). It is composed of two adjoining sub-parts – an area with larger barracks and ‘soft’ constructions, and a larger area were two twin bunkers for warheads are located, together with smaller service buildings and smaller service quarters for the troops. The two areas are arranged along a north-south direction, with the bunker area north of the barracks area.

Today, access to the barracks area is mostly interdicted – you may venture in by foot, but there is a gate which does not allow getting in by car, despite the relatively good condition of the road. The premises are in private hands, and some demolition/reconstruction/conversion works are being carried out here. There is also a service building, looking like a private residence, built in recent times.

Main Gate and Outer Buildings

The main access road features typical prefabricated concrete slabs, found in most Soviet/communist installations everywhere in eastern Europe. Halfway between the external gate and the barracks area, traces of an external wall can be found, with a couple of ‘welcome stones’.

A closer look to the slabs reveal a rather poor quality material used for manufacture. Writings are excerpts of the Soviet constitution, presented as mottoes in Russian, with some communist symbols.

The barracks and some softer constructions date from the Seventies – the frieze on the sidewalls of the buildings tells it quite clearly. The area is protected by a concrete wall, bearing a probably original greenish camouflage.

In the years of operation, there used to be four large apartment blocks aligned in a row, just ahead of the entrance to the area of the barracks. These buildings were for the officials and their families. While still inside the external fence of the base, these apartments allowed more privacy and convenience, forming a de facto little Soviet village in the GDR, segregated from the surrounding German community. This housing has been completely demolished today. However, some trace of correlated ‘civilian’ facilities can be found to the south of the barracks area.

In particular, a swimming pool was built at a certain point in the history of the base, and it is still in a relatively good shape. Changing rooms for men and women are still there. A tall springboard and starting blocks still face the pool, which is apparently watertight, despite the greenish water not being really attractive!

The pool features an outer fence, with a service gate bearing a characteristic Soviet ‘diverging rays’ motif.

Another facility put specifically for comfort in this area is a sauna/bathing house, a widespread Russian tradition. The sauna building in Stolzenhain features several smaller adjoining rooms, with pools, sauna/Turkish bath areas, a central heater, as well as more general purpose sitting rooms with fireplaces. A video studio was also featured in this multi-functional building.

An interesting specimen of Soviet naive art, some frescoes adorn the walls of some of the rooms, with subjects ranging from sea life to women performing ‘spa activities’.

Still outside of the innermost military part, yet inside the external fence of the base, a training ground is to be found to the east of the military area, not too far from the spa building. A walk in the trees along the inner perimeter of the wall of the base is needed to reach this part. A control building with an observation post on top features plenty of instructions for tasks to be performed in a training exercise – in Russian!

Close by, a shooting range for light weapons (rifles, guns) can be found, again with precise indications on the distances to be taken from the target, marked by colored lines on the ground.

Back to the gate to the military barracks area and stepping inside, among the few surviving buildings is a former gym. Despite used as a storage today, the larger hall is clearly a former volleyball/basketball court. A referee chair is still hanging from the sidewall, and sport-themed frescoes decorate the walls.

Former hangars for trucks or technical vehicles can be found in the eastern part of the former barracks area, similar to traces of a fuel pump. As said, most of the former buildings here are now gone.

A special feature in the barracks area is a manhole with traces of a set of cables, pointing towards the highly secretive and guarded bunker area. Communication is of paramount importance for military practice. In the case of nuclear depots so far away from Moscow, a cable connection was implemented not to loose contact under any circumstances between the Soviet headquarters and this peripheral, yet so valuable facility. Pressurized cables were used, such that when an attempt to severe or intercept cable signals was carried out by the enemy cutting the cable, the external jacket was pierced, a loss of pressure was sensed, and an alarm was triggered immediately. Similarly, in the case of an accidental degeneration of the ground where the cable ran, the pressurized jacket was pierced triggering an alarm, allowing the technicians to repair the cable and restore contact.

An old and forgotten Soviet standard service container, typically transported by truck, can be found close to the manhole totally invaded by vegetation. From here, a view to the perimeter concrete wall around the innermost part of the site can be easily seen, with clear traces of camo paint.

Bunker Area

The area of the bunkers is fortified with a concrete wall with barbed wire on top running along all its perimeter. The size of the bunker is immediately apparent from above – you can look at some aerial pictures from a dedicated flight over the area, see this report. There is a gate connecting it to the barracks area. The only other gate to the bunker area, located north on the other end of the complex, opposite to the first gate, is partially obstructed.

For its entire length, the external wall of the bunker area is almost perfectly preserved, and abundant traces of camouflage can be easily spotted all along.

Inside the wall, you soon find a fence of barbed wire with concrete posts, again standard for Soviet military installations. Some sections of the barbed wire are very well preserved, albeit rusty. The overgrown vegetation looks like the only difference between now and the years when the bunker was in operation!

Inside the barbed wire fence, you find traces of an exceptional system of trenches and turrets, which should have granted protection to the innermost part of the complex – the storage bunkers. There are turrets of many kinds, including one which looks like the dome of a tank, re-used for the purpose – a feature also of the Atlantic Wall and the Salpa Line (see here). Such a degree of protection is extraordinary also with respect to other military installations. Abundant traces of barbed wire-holders along the tranches can be easily spotted. The site was clearly considered as an objective of special value, to be seriously defended in case of an attack from the West.

Close to the center of the large fenced area, you soon reach the bunkers (there are a western and an eastern bunker, described below), which despite being mostly underground, feature a small mound on top which allow spotting them from the distance.

Western Nuclear Storage Bunker

Access for the warheads is at the level of the ground. There are two large tight doors corresponding to the two ends of the main hall of the bunker. Below you can see a 3D sketch of the bunker, from a placard found close to Objekt 4001 (the Lychen bunker), describing the inner layout.

By one of the entrances to the bunker is a small loading/unloading platform for two trucks. The apron connecting the platform to the bunker door used to be covered by prefabricated roof tiles – rich in asbestos – and covered with artificial vegetation, of which some traces remain.

The area is overlooked by a firing turret, seating above the front of the bunker.

The external tight door gives access to an airlock, a small square compartment closed to the opposite end by another identical door. This is explained in view of the need to protect the innermost part of the bunker from attacks by means of high-yield weapons. A similar architecture can be found in a Soviet nuclear depot in Szprotawa, Poland (see this post).

From the airlock you get access to a suspended platform, from which you can appreciate the storage facilities of the bunker. There is a main hall, where the warheads were lowered by means of a motorized crane from the suspended platform down to the underground level. From there, they were moved to one of the four long storage chamber, all accessible on the same side of the main hall.

Temperature and humidity of the main hall and storage rooms were perfectly controlled. Ventilation pipes and an impressive array of hangers for heat exchangers can be seen in the main hall.

Access to the underground floor from the suspended platform is only possible with a ladder, passing through a narrow hatch – as usual, it’s hard to understand why the Russians (or the Germans in this case) built passages so narrow and uncomfortable, considering they are not among the shortest human types on Earth… – see this post for another brilliant example…

The storage rooms are very long, and traces of strongpoints for anchoring the warheads safely on ground can be seen surfacing on the floor. The doors between the main hall and the storage rooms, where present, don’t appear to be tight. Most writing is in Russian, but some labels are in German. This can be explained with the bunkers being realized by GDR personnel, upon requirements by the Soviets.

The blue cabinets and piping in the pictures are part of the warhead monitoring plant. Each warhead – the actual number is part of the mystery, but there used to be several tens of them in each of the two bunkers on site! – was kept in a sealed shell, to keep sensitive nuclear material precisely in the required climatic condition. Constantly checking the condition of the warheads was part of the duty of the bunker personnel. For the task, each warhead was moved to the hall and connected to the piping, to take measurements of temperature, pressure, atmospheric composition and similar parameters. In case of an anomaly, the warhead was resent to a major technical facility in the USSR (in particular, in Belarus for the Stolzenhain warheads), for fixing.

To the opposite end of the main hall from the entrance is another identical entrance, with a suspended platform and an airlock. In the case of this bunker, the most external tight door to the far end has been taken off its hinges and put on the floor, whereas that between the airlock and the main hall has been permanently shut.
