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.

Preserved Cold War Bunkers in Northern England

The central role taken by Britain in WWII, firstly containing and then countering the expansion of the Third Reich, is duly and proudly celebrated all around the Country, with memorials and thematic exhibitions, often hosted in historical locations, regularly open for a visit.

The United Kingdom joined NATO as a founding member in 1949, and had already been at the forefront of a European anti-Soviet alliance with France since 1947. The strategic political and military ties with the US, pivotal in putting and end to WWII in Europe, were kept over the following decades, against the menace constituted by the Eastern Bloc. Thanks to its geographical position, and bolstering a nuclear arsenal, strategic bombers and submarines of its own, Britain was a major player of the Cold War.

Despite that, the Cold War left behind comparatively less memories than WWII, with only a handful installations open to the public, and somewhat out of the spotlight. In this regard, this reflects an attitude generally widespread in Europe towards the traces of the second half of the 20th century.

However, for people with an interest in the Cold War age, and more in general for those with a thing for (especially nuclear) warfare technology, there are two really unmissable sights in Northern England, which make for a vivid hands-on experience of the ‘era of Soviet threat’.

One is the Hack Green Secret Nuclear Bunker, with a fascinating history starting in WWII and spanning the entire duration of the Cold War. Here one of the finest collections of nuclear-war-related material in Europe can be found, together with much additional material from the era, in a largely preserved historical site.

Another is the York Cold War Bunker, built in the Cold War age to provide protection to the staff of the Royal Observation Corps (ROC) in case of a nuclear attack, as well as the ability to help coordinating fundamental public functions – health, transportation, food and energy supply, etc. – in a post-attack nuclear fallout scenario.

Both sites are regularly open for a visit, and provide a vivid testimony of civil and military plans and facilities seriously prepared in England for a nuclear apocalypse scenario.

Hack Green Secret Nuclear Bunker

The Hack Green site is located deep in the Cheshire countryside, about one hour driving south of Manchester. Actually, it is in a really secluded location, far from any sizable urban center, and away from major roads. Even today, when this facility is working as a top-level museum, some attention to the signs is needed to reach the site.

Once by the gate, you are immediately driven back in time by the appearance of the tall military-style external fence with official government signs, and by the blunt and in impenetrable appearance of the big concrete bunker – what you see is only the part above ground level! – with a big antenna protruding from the top. Nearby, you can see an apparently still off-limits area, with a now-dead radar antenna and an old Jet Provost trainer in RAF colors.

History

The history of the Hack Green site dates to as back as WWII, when it was established as one of the 12 most developed Ground Controlled Intercept (GCI) centers, out of 21 total nodes in Britain. Essentially based on the airspace scanning radar plants available at the time, the so-constituted ‘Chain Home’ surveillance system was operated by the RAF, and intended to track intruding German aircraft, thus directing air force planes against them. Radar aerials appeared on site at the time, suitable against relatively slow moving propeller-driven aircraft of those years.

With the start of the Cold War, and the need to reconfigure the defense against the USSR and Warsaw Pact forces operating with jet-powered aircraft of increasing speed, several modernization plans were started in Britain, aimed at implementing more effective detection and threat-countering radar technology, like ‘Green Garlic’, and later ROTOR. The latter called for the institution of a chain of detection nodes, not much dissimilar in concept from the older ‘Chain Home’ of WWII, but much more articulated, efficient and technologically advanced. At the time one of the most expensive government-funded operations ever, 66 installations were implemented all over Britain within ROTOR before the mid 1950s, with different roles in the network. The bunker you see today on the Hack Green site was one of them.

Keeping up with the fast-developing offensive technology of the 1950s and 1960s required a continuous update of the defensive network, in particular asking for the addition of intercontinental missiles to the enemy arsenal to counter. The US-led ‘Ballistic Missile Early Warning System’ (BMEWS) included 12 early-warning radar stations around the Atlantic, including a single station in the UK (RAF Fylingdales, Yorkshire, still in operation today). Before BMEWS went operational (early 1960s), triggering a re-organization of all other defense radar systems by the time obsolete, Hack Green took an interim role as one of only 4 radar stations operated by the RAF monitoring all military and civilian traffic through the British airspace, coping with new fast jetliners. The name of the Hack Green radar site in that stage was ‘Mersey Radar North’. Finally, in 1966 the RAF released the site to the government, which put it in mothballed status.

It was in 1976 that a new life began for Hack Green. Starting in 1958, the Home Office invested much in the preparation of an emergency structure, capable of keeping of managing a post-nuclear attack scenario, and keeping the basic public functions active. In the event of a total nuclear war, a failure of the national hierarchy and military chain of command was forecast, as a result of an extensive damage to the infrastructures and communication systems. In order to recover as fast as possible in such an emergency, the UK would split in 11 regions, each with a regional seat of government (RSG). In the region, a civil Regional Commissioner would take a leading administrative role, and would be responsible for coordinating disaster recovery operations, like supplying medical resources, food, water, and reconstructing infrastructures, while waiting for the national government to reactivate its functions. The Commissioner would be aided by the UK Warning and Monitoring Organization (UKWMO), which took over the function and organization of the older Royal Observation Corps (ROC) established during WWII. This structure was further potentiated in the 1960s and 1970s, also introducing a similar regional scheme for the military in case of a nuclear attack.

The seat of the RSG was in the Regional Government Head Quarters (RGHQ). Following some years when it was hosted in Preston, then in Southport, north of Liverpool, the RGHQ for the 10th region (then 10:2, following a split in two halves of this large region) found its home in Hack Green. The former radar facility was potentiated enormously, and set up with the ability to host 160 civil and military staff for 3 months without resupply in case of a nuclear attack on the UK.

Within the framework of the emergency plan for a nuclear attack, the RGHQs all over the UK went on operating until the demise of the USSR in December 1991, to be soon deactivated over the following years. Hack Green was scrapped of all content, and put up for sale in 1993. It was privately acquired in the mid-1990s, and carefully restored in some parts, or being stocked with interesting material from the Cold War era in some of the many rooms.

A tour of the bunker

Access to the bunker is via a concrete slide, and through a metal gate. Originally the male civil servants dorm, the first room you meet is now a kind of storage for items recently incorporated in the collection. These include a jeep, a model of an Avro Shackleton, and interestingly a nuclear warhead. The original system to activate the rooftop antenna is in a cabinet along a sidewall.

The ticket office and canteen are now in the original canteen area of the Hack Green site. Restored to a 1960s appearance, parts of the kitchen furniture are original from the site. Along the sidewalls are several memorabilia items, including some original Soviet emblems, not unusual today in museums on the other side of the Iron Curtain (see for instance here), but hard to find in the UK.

An adjoining room reproduces the environment where the ROC would have worked in case of a drill or real nuclear attack. Among their function was the pinpointing of nuclear explosions. The forecast and monitoring of the fallout is strongly bound to the local weather and winds. This was kept under surveillance through reporting stations scattered on the UK territory (more than 1 thousand), which transmitted information to Hack Green and other RGHQ and UKWMO bunkers (see the York bunker later in this post). They could then coordinate recovery operations, avoiding extreme exposure to radiation of the emergency staff.

Monitoring was through dedicated sensors, and communication through specific transmission gear. Two display cases in the same room feature interesting instruments, training documents, and memorabilia items from the rich history of the ROC, documenting also their activities in WWII.

Ground floor

The Hack Green bunker largely retains its original arrangement. It is composed of a ground and an underground floor. Along the main corridors are interesting examples of the papers produced by the UKWMO, and by the civil defense service during the Cold War. Among them, are leaflets for the population, with best practices in case of a nuclear attack.

Also interesting are more technical posters from the era, either outlining the role of the public organizations monitoring a potential nuclear apocalypse scenario, or providing technical details on the effects of nuclear weapons – what to expect in terms of damage or health issues, depending on the type and local condition of a nuclear explosion.

For sure a focal point in the exhibition of Hack Green today is the display of nuclear warheads, and nuclear-related material. Hosted in a room previously employed by emergency staff, the exhibition retraces with original material, mock-ups, rare pictures and videos, the history of the British nuclear arsenal, managed by the Atomic Weapons Establishment (AWE).

The WE177 was designed to constitute the backbone of the air-dropped nuclear deterrent of the UK. Examples of this bomb are on display together with technical material employed to monitor their status and manage launch or drills. In service between the 1960s and the 1990s in association with larger strategic bombers like the Vulcan, or smaller fighter-bombers like some versions of the Harrier or Jaguar, it could be assembled in some different versions, sharing the same baseline construction, but with nominal yields ranging between 10 to 450 kilotons.

Also on display are pictures and mock-ups of the old Polaris warhead, together with the original casing employed to transport this 200 kilotons item! A US design, the Polaris was acquired by the UK in 1963, to supply the Royal Navy and constitute the UK underwater deterrent. The Polaris missile featured a three-warheads fuse, bearing a total yield of 600 kilotons.

A very rare artifact is the warhead of project Chevaline, a British design to improve the potential of the Polaris, which saw limited service with the Royal Navy in the 1980s. The Polaris/Chevaline was replaced by the Trident missile system, still employed today in the nuclear deterrent role.

Besides the central exhibition of nuclear warheads, the display cases in the same room offer a wealth of super-interesting technical gear and memorabilia related to nuclear weapons. These include components and cabinets of radio and radar systems, to be transported on board aircraft or to be employed on the ground. These parts come from different ages, and from several Countries, including the Eastern Bloc – for instance, a very rare Soviet suit to work on high-power radar antennas for maintenance. Powerful radars actually emit rays with a high power-over-volume (power density) ratio especially in the vicinity of the emitting apparatus. This may even turn deadly for humans (roughly like being in a microwave oven would be!), and precautions are needed when working in such environment.

A really unique collection on display is related to Geiger counters and dosimeters. These include environmental and personal use devices, from various ages and nationality.

Two display cases are dedicated to material coming from beyond the Iron Curtain, most notably from the USSR and the GDR! It is really hard to imagine how this material could manage to come to Hack Green.

Part of the display is dedicated to the civil defense corps of different Countries, with helmets, emblems, papers and uniforms, showing how similar actions in preparations for a nuclear war were carried out in many Nations of continental Europe, also in the Eastern Bloc. Actually, a very close relative of the UKWMO RGHQ control center, with a totally similar function, can be found in a perfectly preserved condition in Poland (see this post).

More memorabilia items come from the history of civil defense in the UK. Among the most rare artifacts are the only surviving example of the ‘Queen’s telephone’, which was employed for enforcing the Emergency Power Act, which among other things may have transferred power to the Regional Commissioner. There used to be one such phone in each of the RGHQ, but all were destroyed for security reasons following the shut-off of the bunkers, except this one, and the one at the other end of the line – in the Royal residence.

An adjoining room hosts a reconstruction of the radar screen room from the age Hack Green was employed as a radar station managed by the RAF. All panels are lit, providing a vivid, pure Cold War experience!

To the end of the main corridor, you can reach another entrance to the bunker, which is nowadays normally shut. However, this used to be the main entrance, and close to it are the control room of the bunker and the decontamination area.

The control room is not accessible, but the large windows allow to take a glance to its original appearance. It is still employed to control electric power and air conditioning. Manned nuclear-proof bunkers are customarily pressurized, sucking contaminated air from the outside, which is carefully filtered for poisons and radioactive particles, and pumping unfiltered bunker air to the outside (see this post for another example in a Soviet bunker).

People entering after work out in the fallout-polluted environment were decontaminated through showers, and used anti-radiation suits were left in an isolated sink still on display.

Before leaving the ground floor, you can find on the ground level the female dorm for the staff of the RGHQ bunker. In the same room, an original system for communicating on the very low frequency bandwidth has been put on display. This Cold War relic could be employed to issue orders to the strategic submarine force. This very cabinet was employed by Prime Minister Thatcher for ordering the attack against the Argentinian ship General Belgrano.

A final room on this floor is the sick bay, sized for the staff of Hack Green only, but equipped to manage health issues resulting from the exposition to a nuclear attack.

Underground floor

Descending to the underground floor is possible via the original stairs. The first room you meet features an exhibition of original Soviet uniforms, belonging to some high-ranking officials from various branches of the Red Army. Really hard to see in this part of the world, their origin is well documented.

Close by, is a small display of military material from the Soviet bloc, ranging from original weapons, to communication systems, emblems and instructional posters for the troops (similar to what you can find in dedicated museums in former Warsaw Pact Countries, like here or here).

Nearby is a communication room originally employed by the military staff of the bunker, working in parallel with civil servants in the management of the nuclear emergency. Original radio transmission gear of military standard is still in place.

Before entering the core preserved area of the bunker, i.e. the rooms of the RGHQ, you can find the original water and air supply systems, and the corresponding technical cabinets, in a big room on the underground level.

The rooms of the RGHQ are all interconnected, and located to the side of the corridor on the underground floor. The way they look is from the days of activity of Hack Green as a RGHQ, i.e. the 1980s. Typical Cold War technology from the time is featured in this area.

Firstly, you enter the warning room, which used to be the contact point of the RGHQ with the national surveillance system. By design, the BMEWS at Fylingdales should have picked up an incoming ICBM within 30 seconds from launch, spreading an alert signal at all levels. This would have been received here and by the entire civil defense system within 90 seconds. This would leave roughly 4 minutes (out of a total of around 6 minutes for the missile to come to Britain from the Eastern Bloc) to tell the population of the incoming missile, which would happen through some thousands sirens scattered around the UK. The physical alarm signal management system was called HANDEL, and was employed from the 1960s to 1992. The apparatus on display at Hack Green, a node of HANDEL, is notably still working, albeit disconnected.

The warning room can be accessed directly from the Commissioner’s room, both an office and private room. Original maps and furniture can be found in this room, the only private one in the bunker. Immediately next to it is the cipher office, a communication office connecting – at least in non-emergency conditions – the center with the external world. Ciphered language was employed for safe communication with governmental offices, both domestic and abroad.

Next are a conference room, for meeting within the staff of the RGHQ, and a broadcast studio. The latter was focused on radio broadcast instead of TV, since the latter would not work in case of a nuclear attack. The idea was for the Commissioner to communicate directly with the administrative region, possibly repeating messages of national significance, or instructing about local disaster recovery actions, evacuation operations, etc.

The tour goes on with a very interesting area, stuffed with original electronic and communication material. Communication from the bunker to the other similar bunkers withing the UKWMO was possible through a dedicated system called Emergency Communication Network (ECN). The main function was that of constantly updating the map of the fallout and of the operations taking place at all levels, including all surviving infrastructures. Many maps and teletypewriters, original components of the system, are part of the display.

The ‘brain’ of the system was the Message Switch Exchange (MSX). A top-tier system elaborated by British Telecom in the 1980s, it looks exceptionally complex. The lit cabinets and modules provide a really vivid impression of how it should have looked like back in the Cold War years. The electronic cabinets and wiring driving to the rooftop antenna are still lit as well.

A rare, incredible portable satellite communication antenna is on display. This was employed in peacetime condition, and stored inside the bunker when under attack.

The screens where the meteorologists and nuclear scientists displayed all the information gathered and prepared forecasts are another unusual Cold War sight.

Perhaps unexpectedly in a 1980s hi-tech environment, a purely analog, wired telephone exchange system is on display. This is original as well, and was kept in service as a ‘last line’ backup system within the ECN until 1992, should the futuristic MSX system fail under an attack.

A complement to the exhibition of the RGHQ is the fire control room, where a big screen and several communication consoles were employed for directing firefighting actions at a regional level. Following the experience of Nagasaki and the extensive nuclear tests of the 1950s, it is known that fires resulting from the extreme temperature and radiation intensity associated with a nuclear explosion are possibly even more dangerous to buildings and infrastructures than the shock-wave itself.

A display which is not original from Hack Green, but found an ideal home in this bunker, is made of a reconstructed room from the Regional Air Operation Center (UKRAOC), which would gather information from the BMEWS. The material on display used to be at RAF High Wycombe, where the UKRAOC facility was located in the Cold War years.

Fed by the BMEWS early warning station at Fylingdales, the apparatus in this room was constantly updated on the defense situation. A Soviet ICBM attack would be detected here, and from here the alarm signal to the entire national civil and military defense system would be triggered. This really one-of-a-kind reconstruction is really evoking, with the original panels all lit, and a dim light background!

A final room on the underground floor hosts a reconstruction of a Soviet missile launch room. Perhaps not accurate as a reconstruction, it is however centered on original material and memorabilia items from the Soviet bloc. This area has been employed as a set for movies.

At the base of a second stair well ascending to the ground floor you can find a reconstruction of one of the more than 1 thousand peripheral posts of the ROC. Such posts, scattered on the UK territory, gathered information for the RGHQ, and constituted the ‘sensors’ of the nuclear attack detection network. The technical gear includes over-pressure and radiation intensity transducers.

Getting there and visiting

The bunker is in a very secluded location, about 25 miles west of Stoke-on-Trent, and roughly 60 miles from Liverpool and Manchester. Very little advertised in the area, and not much known to the general public even in the UK, this hidden gem can be reached very conveniently by car, not much conveniently with public transport. The exact address is French Ln, Nantwich CW5 8BL, United Kingdom.

The bunker was built far from the crowds. Do not be worried as you see the road getting narrower and you feel like your NAV is taking you to nowhere – you are probably on the right path! Once there, you will find a large inside parking, and a top-level management of the entire facility.

Visiting is on a self-guided basis, with tons of explanatory panels and illustrations allowing to make the most out of your visit even if you have just a normal interest and preliminary knowledge of the topic. For a specialist, this super-interesting, one-of-a-kind site may require at least 2 hours for capturing the details, and possibly take pictures. Website with visiting information here.

York Cold War Bunker

Besides the impressive Minster and the beautiful historic town, York has the distinction of being the seat of one of the few Cold War bunkers preserved in the UK. Differently from Hack Green (see above), the bunker in York was installed relatively late in 1961, in the middle of the Cold War. Since then and until the collapse of the USSR, it acted as a node in the UK Warning and Monitoring Organization (UKWMO), collecting information and coordinating emergency actions around York in the event of a nuclear attack. A cluster of reporting points was linked to the bunker in York, which took the name of Headquarters of the N.20 Group within the UKWMO.

An eminently intelligence collection and information relay facility, the bunker was manned by the Royal Observation Corps (ROC), who provided voluntary civilian staff to support the monitoring and communication functions of the bunker in the UKWMO network. The bunker ceased operations and was basically sealed in 1991. Until that time, the ROC ran the facility, carrying out regularly scheduled drills and simulations. The bunker was designed and sized to offer its staff a self-support ability of a few weeks in a nuclear fallout scenario. Besides all supporting facilities, including water tanks, pumps and power generators, the facility was centered on a set of sensors for nuclear blast detection, as well as provision for fallout forecast and monitoring.

The bunker has been taken over by the English Heritage, a structured nationwide historical conservation association, which restored the site and opened it to the public.

The York Cold War Bunker is not far from the historical center, yet in a quiet residential area. Access is from a small parking area among low-rise buildings. The greenish paint of the concrete walls and the tall metal antenna on top cannot be spotted from much farther away than the parking itself. Curiously, the pedestrian door of the bunker stands some feet above the ground, and can be reached via a concrete stairway. Then once on top and inside, you need to descend some flights of stairs to get underground.

Compared to the Hack Green bunker, the York group headquarter is more cramped, with smaller rooms, lower ceilings and narrower corridors.

The first part of the visit covers the supporting facilities. These include a ventilation system, which as customary for nuclear-proof bunkers (but the same is true for older bunkers dating from WWII) filtered the incoming air and ejected the inside air, basically pressurizing the bunker environment with respect to the outside atmospheric pressure. This avoided passive ingestion of contaminated air from the outside.

A power generator and a water pumping system are also visible. A control panel for all the plants has been preserved, similar to the machinery in this area, dating from the time of construction.

The centerpiece of the visit is of course the reporting room. The reason for putting a headquarters in relatively low-sized York was the presence in the area of significant food production industries, as well as of a major railway node in Northern England. Furthermore, military facilities like the only BMEWS station in the UK happened to be in Fylingdales, northern Yorkshire. These features would make York a valuable strategic target for an attacking enemy. The main function of the bunker within the UKWMO was that of ascertaining the position and intensity of a nuclear explosion on the territory covered by its jurisdiction.

Anticipated by the early warning ballistic missile detection system protecting the UK, the hit could be recorded by the sensors available in the bunker or in other reporting points scattered around in the country. The bunker would then try to predict and follow the evolution of the fallout. This would allow coordinating emergency and recovery actions including fire suppression, medical evacuation, water and food transport and supply, etc.

The central reporting room looks mostly like an operations room in a military headquarter. It is structured on two levels, with large maps and boards for visually updating the situation and writing information. Batteries of telephones and teletypewriters allowed obtaining communications and sending updated information to allow emergency services as well as decision centers to carry out post-attack operations. This system was not dissimilar from the counterpart beyond the Iron Curtain (see for instance this center in Poland).

Nearby the reporting room, the components of the sensor suite allowing to detect the position and intensity of a nuclear explosion are on display.

The first is the bomb-power indicator (BPI). The working principle is that of reading the over-pressure caused by the shock-wave invariably produced by an explosion, and particularly intense for a nuclear explosion, releasing an immense amount of energy in a small volume and within a very short time. The supersonic traveling shock-wave is responsible for the mechanical breaking of building and superstructures, like antennas, suspended power lines, bridges, piers, etc. Being a wave of pressure, its intensity can be measured by pressure transducers, which for the BPI show the reading on a simple analog dial.

The transducer, seen handing from the ceiling in the exhibition, would stand on the rooftop of the bunker, exposed to the explosion. This type of sensor was also installed in smaller reporting points scattered over the territory of the UK.

A second sensor was the ground zero indicator (GZI). Here the working principle was also very simple. The main element in the GZI is a metal drum with a small hole in the side, and a piece of photographic paper covering the inside surface of the cylinder. An explosion would send a high-energy light beam through the hole, producing an impression on a precise point on the paper. By positioning in a very accurate way the drum on its pedestal on top of the bunker, according to a precise fine-tuning, it was possible to retrieve the direction of the incoming beam. By composing the reading of more than one precisely-located drum, it was possible to pinpoint the position of the explosion by triangulation, both in terms of geographical position and altitude. The latter is a very relevant practical information, since for instance the quality and hazard of the fallout are strongly related to the proximity of the explosion to the ground.

The GZI, a purely analog sensor, had the odd feature of requiring collection of the photographic paper by venturing outside of the bunker after and explosion, i.e. facing the fallout.

The third and most evolved system on display is an AWDREY computer. The name stands for Atomic Weapon Detection Recognition and Estimation of Yield. This artifact is very rare to see, and a quite refined piece of engineering for the time. It was supplied to 12 headquarter bunkers of the UKWMO, including York, and was operative from the early 1970s. The computer is the computational part of the system, whereas the detection system was based on a sophisticated transducer put outside, on top of the bunker. The working principle was much more sophisticated here, and related to the evolution of the intensity of the radiation coming from the core of the explosions in the first instants of the detonation process. Several stages of a nuclear explosions happen in a row on a scale of a few millionths of a second. These include a predictable oscillation of the intensity of radiation. The exact features of this oscillation are correlated to the yield of the explosion. The ability of AWDREY to collect and interpret data from the early stage of the explosion would allow it to reconstruct the position and yield of the explosion at once.

Tuned on experimental data from nuclear testing in the field, this system delivered good general performance, with some inaccuracy in case of intense atmospheric phenomena taking place – or during fireworks, when the York system was apparently misled in one occasion, interpreting it as a Soviet attack!

The tour is completed with a view of the dorm for the civil servants of the ROC, and with a short exhibition on some historical and political aspects of the Cold War.

Getting there and visiting

The York Cold War Bunker is professionally managed by the English Heritage. Visiting is only possible with a guide. Please note that as of 2022, pre-booking is strictly necessary, since there is no ticket office on site. The guided tour lasts about 45 minutes, including a well-crafted introductory video. At the time of writing, only the first underground floor is open for a visit, but plans for an expansion of the visible part of the facility are being drafted.

The tour is very interesting and detailed, with some educated humor to make it more enjoyable! For specialists, it will be too quick, especially if you like to take pictures. However, the site indeed deserves a careful look also for the more technically-minded people, especially considering the little number of similar facilities open in Europe – and of course in the UK, where it is a one-of-a-kind destination, and a true must for Cold War historians.

The location is about two miles west of York Minster. Convenient to reach by car, several public parking lots are available in front of the gate or in the neighborhood. The exact address is Monument Cl, Holgate, York YO24 4HT, United Kingdom. Website with full information here.

Aircraft Collections in Norway

The ‘Norwegian chapter’ in the book of aviation history is a peculiar and interesting one. Similarly to virtually every Country in the western world, in the early age of aviation small manufacturing companies appeared also in Norway. Despite meeting with little success in the long run, they contributed in creating momentum around those ‘novel flying machines’. Norway, with a sinuous coastline stretching for some thousands miles from the latitude of England up north to where the European continent ends, and with a land largely covered in snow for many months per year, has been an ideal place for the development of a local air network since the early days of aviation. This created an alternative link between smaller communities and industry centers. As a matter of fact, similarly to Greece, Norway is among the top employers of smaller aircraft for commercial routes in Europe still today.

To the same early era belong the now almost mythological arctic expeditions, carried out also by air – by plane or airship – and almost invariably departing from Norway. The well-known Norwegian explorer Roald Amundsen was an advocate of air explorations, and his primary contributions to geographical explorations have constituted in some cases milestones in aviation history.

Despite a significant down-scaling of its Armed Forces in the post-Cold War scenario causing a strong reduction of the military presence in the Country, Norway has been in the focus of massive military operations since the 1930s.

In particular, both its geographical position and natural resources met the appetite of the Third Reich, which successfully invaded Norway in a blitzkrieg campaign in late spring 1940. Through an action based strongly on airlift capacity, German cargo planes relocated personnel and material very effectively to Norway. The crown and government were forced into exile in Britain, and with it also the military chain of command. Actually, the air force academy was moved to Toronto area, Ontario, where the military facilities of Norway got the name of ‘Little Norway’. New Norwegian pilots were relentlessly trained there, preparing them to repel the enemy from their Scandinavian motherland.

The Third Reich managed to keep a grip on southern Norway until its collapse and the end of WWII in Europe. Having witnessed the failure of neutrality as a foreign policy, in the rapidly deteriorating post-WWII scenario and the beginning of the Cold War between the Soviet-led eastern bloc and the free democracies of the western world, Norway joined NATO as a founding member.

Since then and for more than four decades, Norway was on one of the ‘hot’ fronts of the war, with a border-crossing point with the USSR, and a privileged position to patrol the skies over the shipping routes leading from the highly-militarized Kola peninsula into the Atlantic Ocean (see this post). Keeping a constant watch on the air, surface and submarine movements of the USSR was a task brilliantly covered by the Norwegian Air Force and Navy for the entire duration of the Cold War.

Today, western world issues like climate-related hysteria and hardly shareable, deeply ideological so-called ‘carbon neutrality’ policies promise to definitively clip the wings to sport, private and commercial aviation especially in this Country, through an unprecedented technological leap back. Similarly, the (today, so evidently) short-sighted post-Cold War dismantlement of military power in Europe has impacted military forces also in Norway.

However, the memory of the glorious years when this proud Scandinavian Nation has been on the forefront of aviation technology and in the focus of military action are duly relived in two wonderful aviation collections, celebrating what can be achieved through technical skill, courage and good national ideals.

One of these collections is the Norwegian Aviation Museum, located east of the airport of Bodø, a coastal town on the Norwegian Sea, not far north of the Polar Circle. The other is the Norwegian Armed Forces Aircraft Collection, located just west of Oslo-Gardermoen Airport, in the south of the Country and close to the capital city. Both museums host world-class collections, really worth a detour for aviation-minded people from whatever continent, and for the general public as well, as can be possibly perceived from the pictures in this post.

Photographs in this post were taken during a visit to both destinations in August 2022.

Sights

Norwegian Aviation Museum – Bodø

The Norwegian Aviation Museum in Bodø is located on the northeastern corner of the airport, dominating this coastal town north of the Polar Circle. The airport was founded back in the 1920s, strongly potentiated by the Germans in WWII, and extensively used over the Cold War decades for mixed military and civil use. Today, it is mainly a commercial airport, with some residual military activity. However, the Air Station at Bodø shows evident traces of a military past – aircraft shelters, bunkers and large antenna arrays point the hilly panorama south of the runway.

The museum covers many aspects of the history of aeronautics in Norway. Both civil and military aviation are well represented, the respective collections being hosted in two adjoining large halls, merging into the central atrium – featuring a Northrop F-5 in the colors of the Royal Norwegian Air Force (RNoAF). This type has been the backbone of the RNoAF in the latter decades of the Cold War years.

Civil aviation hall

The proposed path in the civil aviation hall follows a chronological order, and starts with a display of memorabilia from the early aviation years and from the age of the adventurous polar explorations. The items on display include flags, historical pictures, personal belongings taken by explorers on polar exploration trips and many interesting explanatory panels.

Aircraft on display include rare early seaplanes, employed to establish transport services. These are put side by side with more modern aircraft of the company Widerøe, which today is responsible for most of the short-range high-frequency services linking the scattered settlements in the northern part of Norway – up to North Cape.

Nice advertisement posters are displayed to retrace the history of some classic airlines, including the all-private Braathens, once a major airline from Norway, and telling about the foundation of SAS – which incorporated also Braathens at the turn of the century – which stands for ‘Scandinavian Airlines System’. It is still today a big carrier linking Northern Europe and the world. These companies were among the world first massively flying polar routes, thanks to on-board instrumentation specifically made to tackle the navigation issues showing up when flying close to the poles.

A turning point in the history of Braathens has been the introduction of jets, in the form of the Fokker F.28, for which this airline has been a launch customer. An exemplar of the F.28 is partly preserved in the museum, allowing to check out the fully analog cockpit.

Helicopters, including one with a special pod hosting an entire berth for SAR operations, are also well represented. The Police is clearly using the latest models of rotary wing technology.

A rare aircraft on display is a British-made Britten-Norman Islander, once operating in the colors of the local company Norving. Very evocative pictures show the unusual scenarios often faced by airlines operating in near-polar regions!

Another peculiar mission covered by aircraft in Norway has been that of territory imaging and survey, including for archaeology in the search for ancient viking remains, typically hard to see from ground level. A Cessna 337 Skymaster push-pull originally tasked with this mission is on display. This type is pretty hard to see in Europe, but has enjoyed even a significant military career in the US (see this post).

A big bird on display is a beautiful original Junkers Ju-52 three-props seaplane. This is one of four originally in the fleet of the Norwegian flag carrier ‘Det Norske Luftfartselskap’, established in the 1930s, and operating with a mixed fleet of British, German and American models.

The cockpit of the Junkers has been put in a display case to be admired more easily.

Among the many other items on display in the civil aviation hall, you can find an original wind tunnel model of the Concorde, aircraft remains from an accident, and some unusual or one-off aircraft models.

Military aviation hall

The hall dedicated to military aviation starts again following the timeline of aviation history. The early-age manufacturers appearing in Norway when aircraft were still a totally new technological novelty are represented with dioramas of technical shops, scale models and historical pictures. Some aircraft dating to the pre-WWII years are also on display.

However, a major subject covered in the display is that of WWII. Norway was conquered by the invading German forces in a short and aggressive campaign in Spring 1940. Well planned from a strategic viewpoint, this operation included the capture of the airport of Oslo – the old field of Oslo-Fornebu – on the 9th of April, which was then used as a major base for landing transport aircraft, unloading military staff and material in the most populated area of the Country.

The landslide Third Reich invasion forced the government and the military chain of command to withdraw to Britain. An agreement was then settled to establish a military flight academy near Toronto, Ontario, to supply the Norwegian armed forces with new pilots, to carry out offensive operations from Britain.

The collection features many interesting items from WWII period. From a balcony you are offered a view of the collection, and a vantage view on the relic of a Luftwaffe Junkers Ju-88, transported to the museum after recovery.

The air operations in the invasion of Spring 1940 are documented with interesting scale models and dioramas, as well as much technical material retrieved from the days of German occupation. This includes cameras for photo reconnaissance, Third Reich military maps of the region, flags, aircraft engines, and many historical pictures.

From the same era, the cockpit of a Soviet Ilyushin Il-2 Sturmovik, documents of the air actions against the Third Reich occupants, and others concerning the history of ‘Little Norway’ – the Norwegian military training facilities in Canada – are also on display.

Aircraft displayed in this area include restored or partly reconstructed examples of a De Havilland Mosquito, a Supermarine Spitfire, as well as a Focke-Wulf FW190 and a Messerschmitt BF-109 on the German side.

All these birds together make for a really unusual and evocative sight today! Especially the German fighters are really rare to find, and their condition and presentation is really eye-catching.

Further aircraft from the time include a North American Harvard trainer, and a big Consolidated PBY Catalina seaplane used for patrol. The latter looks really massive hosted indoor, compared to smaller fighter aircraft!

Anti-aircraft guns and a pretty unusual radio emitter/transmission station, employed as beacons for helping instrumental navigation in the war years, are also part of this interesting display.

Next to the WWII area is the Cold War section of the display. Following the bad WWII experience with a policy of international neutrality, resulting in an invasion by a powerful enemy force, following the escalating divergence between the western Allies and the USSR, Norway opted for joining NATO as a founding member.

The alliance with the US and Britain, similar to other NATO Countries, meant a substantial supply of American and (at least in the beginning) British military supply. A North American F-86 Sabre and a Republic F-84 Thunderjet are two beautiful representatives from the early Cold War era. Similarly, a De Havilland Vampire is hanging from the ceiling.

A slightly more modern item is a Lockheed F-104 Starfighter. Not much employed in the US, it covered the interceptor role along the border with the Eastern Bloc in Norway, Federal Germany and Italy for many years.

Historical pictures tell – among many interesting subjects – about other aircraft, like the Lockheed T-33 Shooting Star, as well as the F-104 and the F-5 involved in interception and escort flights, shadowing Tupolev Tu-95, Antonov An-12 and other USSR machines flying over international waters or scraping the border of Scandinavian airspaces – quintessential Cold War memories!

Possibly a reason for Bodø having grown to further fame in the aviation community of Western Countries is the presence here of a real Lockheed U-2 spy plane. This aircraft can be found in Europe only at the Imperial War Museum in Duxford, Britain, and here. Actually, a curious fact about Bodø is that it was a designated destination or an alternate (emergency) airfield for the perilous overflights of the USSR, carried out with the Lockheed U-2, and later with the Mach 3+ Lockheed SR-71. Actually, the latter landed here in one occasion, whereas the ill-fated mission of Francis Gary Powers, downed by Soviet SAMs while en-route north of Kazakhstan from Peshawar, Pakistan, had Bodø as a destination (see this post for pictures of the relic in Moscow).

The U-2 is displayed so that it is possible to both appreciate its slim shape and large wing span, and also get near to its cockpit. However, its installation and lighting inside the hall – and the fact that it is black… – make it a rather difficult target for photographs. Next to the aircraft, historical pictures and schemes tell about the mission of Francis Gary Powers. Interesting tables for the interpretation of photo intelligence are also on display.

Still in the Cold War part of the museum, a very unusual and interesting section is centered on the facilities and technical gear for the detection and monitoring of airspace intrusion, for early warning and for alerting the air defenses of the National airspace.

This secretive and little publicized branch of the military kept its ears and eyes constantly pointed on the moves of the colossal Soviet neighbor, recording every single movement – look for the super-interesting registry of USSR aircraft movements! – and constantly updating the situation, in order to be ready to counter a sudden ‘turn for the worst’, in case of an actual attack.

Interestingly, much of the electronics here is US made, as can be seen looking at the product tags.

The arsenal that could be employed to counter an air attack included the Nike-Ajax and later Nike-Hercules surface to air missiles, deployed along the border with the Eastern Bloc also in Denmark, Germany and Italy (see here and here).

Just to complete this incredible Cold War exhibition, an interesting and pretty unique air-dropped WE-177 nuclear bomb case is on display!

More modern addition to the aircraft collection include a General Dynamics F-16 Fighting Falcon and some helicopters.

A latter interesting part of the military exhibition showcases an array of aircraft-mounted cannons from various ages, showing their precision and their effect on the same target. You can appreciate the effects of the technical evolution of these weapons.

Examples of air-launched missiles and sonobuoys, and a fine array of flight suits showing the evolution of their design, conclude this exceptional museum.

As a plus, the old control tower of the military air station has been turned into a panorama point, where you can watch air operation on the actual airport, and also listen to air traffic frequencies!

The gate guardians include a Bell helicopter and an old glorious Hawker Hurricane from WWII.

Visiting

The museum is located at Bodø airport, and can be spotted pretty easily when entering the town. Bodø can be included – or considered as a starting point – in many tours of Northern Norway. The museum offers a large and convenient parking. It can be toured in not less than 2 hours for aviation-minded people. The website is here.

Norwegian Armed Forces Aircraft Collection – Oslo-Gardermoen

Coherently with its name, this wonderful collection is focused on military aviation in Norway. Most aircraft having served in the RNoAF at some point in history are represented, as well as some from WWII – not only from the Allied side, but most notably some rare exemplars from the Third Reich.

A great feature of this museum is also the architecture of the display. Put in a U-shaped building to the southwest of Oslo-Gardermoen airport, the aircraft are in most cases sufficiently far from one another to allow moving around freely, getting an unobstructed view from different angles. Furthermore, the natural lighting from the top windows is ideal for pictures (similar to the solution adopted in the Estonian Aviation Museum, see here).

Late 20th century

The display starts with the Northrop F-5, which is represented by three exemplars, interspersed with a single example of a General Dynamics F-16 Fighting Falcon – currently in use with the RNoAF, to be replaced by the Lockheed Martin F-35 Lightning II. The Freedom Fighter has been the backbone of the RNoAF for the latter years of the Cold War, being flanked and substituted by the Fighting Falcon, and now by the Lightning II.

The aircraft on display are two F-5 Freedom Fighter, i.e. the light fighter version – one in a distinctive tiger painting – and one RF-5 Tigereye, which has been developed from the original design into a capable photo reconnaissance aircraft.

Walking beneath the F-5 reveals many details, for instance the landing gear mechanism, the missile pylons and anchoring system, and JATO bottles for reducing the take-off distance.

A J85 jet engine – there were two for each F-5 – is on display, with the afterburner pipe mounted past the turbine exhaust. A choice of missiles and pods can be seen close to the ‘tiger painted’ exemplar. The latter can be boarded. The fully analog cockpit shows much standard instrumentation for flight control, navigation and engine management, but also an armament panel with weapons selection and activation switches. Also interesting are the parachute deployment lever, for the arresting parachute, or the underwing load jettison system.

The RF-4 reconnaissance aircraft features a nose camera, with a prominent lens which can be easily checked out. Similarly, the hatch of the port 20-mm cannon has been left open, showing the cannon body, barrel and the very neat ammo supply system.

Next to these aircraft are a Lockheed F-104 Starfighter in a two-seats trainer configuration, and the front section of another exemplar with the original cockpit, which can be boarded. The J79 engine of the Starfighter, apparently originally from Canada judging from the Orenda labels on some components, has been taken out of the fuselage and can be appreciated in all its length (with the afterburner pipe to the back).

The cockpit of the Starfighter is cramped, with little legroom and a very limited front visibility. It is fully analog, similar to the F-5.

In a corner of the hall, an original simulator – apparently for an F-16 – has found a new collocation, possibly from a military aviation academy.

Early Cold War

The next part of the display offers the sight of a full array of fascinating, well-preserved aircraft from the early Cold War period. The first is a North American F-86 Sabre, with an attractive golden front intake decoration. Walking around and looking closely, many particular features can be spotted, including the leading edge slats. A ‘used’ Martin Baker ejection seat shows the little damage resulting from actual employment in case of emergency.

Next is an improved version of the Sabre (F-86K), which features a very different intake, such to accommodate in the bulbous nose a powerful radar antenna. The latter could work in conjunction with a computer, and offered a substantial help in increasing the offensive capability of this fighter, which could also be operated in all weather conditions.

A nice gem of the collection is an original portable cabinet for testing the General Electric J47 engine. This cabinet looks like a suitcase, but it could be positioned standing on its legs, linked with connectors to the on-board systems, and could show the working condition of the engine in a mounted configuration. The monitoring instrumentation is fully analog. It would make for a great item for collectors of Cold War technical gear!

Then follows an Republic F-84 Thunderjet early jet fighter, with its neat lines, wing tip tanks, and an under-fuselage spoiler in a deflected position.

Nearby, the rather different – despite the similar code – Republic RF-84F Thunderflash photo reconnaissance aircraft prominently displays its big-diameter optics in the nose.

The really elegant design of a Lockheed T-33 can be appreciated next. The air intakes are really works of art, and the bare metal color just adds to the vintage line of this early design.

Similarly graceful is the iconic De Havilland Vampire, the only British addition to this US-dominated aircraft display from the Cold War era. With its distinctive twin-boom tail, the typical De Havilland vertical fins dating back to the pre-WWII propeller-driven examples, the shrouded jet engine totally disappearing in the body of the aircraft, with small, fenced intakes on the leading edges of the wing, this aircraft looks like a really good balance between engineering-driven design choices and pure elegance.

WWII aircraft

A central section of the exhibition is centered on WWII-era aircraft, starting with two Supermarine Spitfire, one hanging from the ceiling, and one sitting on its wheels, in a greenish color and RNoAF emblems.

What follows is a pretty unique US-made aircraft, a Northrop N-3PB seaplane, ordered as a sea patrolling aircraft by Norway, but not reaching Scandinavia in time before the German invasion. It was then employed as a sea patrol from Iceland by the Norwegian forces in exile. Possibly looking not so conspicuous in pictures, it is a rather massive bird. It shows an interesting floatplane design, where floats are anchored to the wings through aerodynamically profiled struts, so as to reduce drag as much as possible.

Walking around it, you can notice the relatively light weaponry hanging from the fuselage bottom, the down-firing back cannon for defense, and the detachable wheels to pull the aircraft ashore.

Then a very rare bird follows – a German Heinkel He-111 bomber from WWII! Restored in a mint-looking condition, this aircraft makes for a unique sight in the panorama of aviation collections.

This iconic aircraft from the Third Reich, much known to aviation-minded people especially in connection with the early landslide campaigns of the Third Reich in Europe and for the Battle of Britain, can be examined from very close and beneath, unveiling some interesting peculiar features. For example, the bomb bay features vertical square-section separated ‘blisters’, a totally different solution with respect to larger US bombers from the age.

The underbelly shooting pod allowed the cannon operator to ‘rest’ in a laid down position. The front cannon is clearly asymmetrically placed with respect to the aircraft centerline, following a side curvature of the nose cone such to increase pilot’s visibility.

Close by is another incredibly well-preserved addition from the Third Reich’s Luftwaffe, a Junkers Ju-52 transport in fashionable military colors.

The Ju-52 and He-111 were the main characters involved in the blitzkrieg attack to Oslo-Fornebu, the now bygone airport of central Oslo, which was the stage of a massive air-launched German attack in April 1940, a substantial contribution and a prelude to the complete invasion of Norway. Both aircraft are surrounded by a set of accessories from the time, including searchlights, fuel tanks, spare parts, anti-aircraft guns and even service trolleys with skis to be used on snowy aprons! The ensemble is really quite a sight.

From roughly the same age is also a perfectly preserved Douglas C-47 Skytrain – a true war veteran! Preserved in the colors of the RNoAF, it was originally incorporated in the USAAF and employed in action in Europe since mid-1944. It flew during the Berlin Airlift, operating in and out West Berlin transporting goods during Stalin’s blockade of the town in 1948-49 (see this chapter). It later joined the RNoAF and was employed for radar tuning and for transport until the mid-1970s.

The color scheme of the RNoAF looks great on this C-47, and the presentation among some airport service vehicles from the time adds to the display.

Further recent aircraft

Approaching the extremity of the U-shaped building, you can find a De Havilland Twin Otter with skis, some classic helicopters, some aircraft undergoing restoration – including substantial remains of a Junkers Ju-88 bomber from the Third Reich! – and a massive Lockheed C-130 Hercules.

The latter is possibly the aircraft in the collection having been retired most recently. It has been deprived of its vertical fin, which simply couldn’t fit inside the building, but the rest is almost complete. The engine pods are opened, so that you can see inside. An array of JATO bottles to enhance take-off performance has been anchored to the side of the fuselage.

The aircraft is on display with the back and side doors opened, so that boarding its preserved interior and cockpit is indeed possible.

Inside the cockpit, chance is you meet a living legend, the flight engineer of the RNoAF Mons Nygård, who will explain you the features and operations of his aircraft! The man joined the Armed Forces in the late 1950s until the 1990s, with a military career spanning a big part of the Cold War. He flew extensively the Hercules, as well as other aircraft including the Lockheed P-3 Orion, logging a staggering  more-than-17’000 hours in flight!

We could interview him about his career, which unfolded several nice anecdotes and memories from the Cold War years, and a real passion for his super-reliable aircraft and for his job. It’s no wonder the Hercules, being designed in the 1950s, is still in service with many Armed Forces of the world.

Anti-aircraft defense system

Finally, the exhibition includes Nike-Ajax and Nike-Hercules anti-aircraft missiles (SAM). Installed in batteries against an attack from the USSR also in Norway (see for instance this preserved battery in Italy, this in Denmark, or this ghost one in former Federal Germany), these nuclear-capable massive missiles were in service typically between the 1950s and the early 1980s, becoming by then obsolete.

Of great interest for technically-minded people are some of the inside components of these missiles, including components of the guidance system and some electronics, which can be seen in display cases, as well as technical vehicles for launch control, radar operation etc.

Other lighter anti-aircraft weapons from the Cold War era are displayed nearby, thus covering also this interesting subject in good detail.

Balcony

The visit may be concluded with a walk along the inside balcony, from which a good view of all the aircraft just mentioned is obtained.

On the same balcony, you can find also many trainers once used for teaching young pilots the basics of flight. Some are classic models belonging to the era of Little Norway and WWII, when training for freshly recruited pilots was carried out in Ontario, Canada.

The gate guardians for this beautiful collection are an F-5 and an F-104, the latter in the greenish colorway seen also in the collection in Bodø.

Visiting

This fantastic collection can be found in the southwestern corner of the premises of Oslo-Gardermoen airport, the main airport serving the Norwegian capital city.

The museum is administrated by the Armed Forces.

Visiting for the aircraft enthusiast may be very rewarding and may take more than 2 hours, since the exceptional state of preservation of the artifacts and the many details you can explore through a walk around very close to the aircraft invite to spend time inside. You have also chance to speak with former military crew, which adds much to the experience. Very good photo opportunities for an indoor collection.

Large free parking ahead of the entrance, with picnic facilities. Nice model shop by the ticket office.

The museum is normally open on weekends, but further visits may be scheduled out of these opening slot. Please check the info on their website here.

Bunker Kossa – A Preserved Cold War Military Bunker in the GDR

The history of the underground installation in Kossa-Söllichau begins in the 1930s under Hitler’s rule.

In 1935, an affiliated company of the German chemicals giant WASAG, named Deutsche Sprengchemie Moschwig and devoted to the mass production of explosives for warfare use, had a new plant built in the rather uninhabited forest area between Leipzig and Wittenberg.

The plant, codenamed ‘Beech’ (or ‘Buche’ in German), was updated over the years and turned into a major production center for several models of shells and high-explosive charges. A primary contractor of the German Army, the company also held relevant patents, including one for hollow charge grenades.

By the end of WWII in April 1945, when the area fell under Soviet control and production was halted, the plant counted 3.600 employees, and had a production capacity of around 600.000 ammunitions per month. It had been provided with a dedicated road and railway connection, and built mostly underground, with several concrete bunkers surfacing from the grassy terrain around.

Following the Potsdam agreement (July 1945), the area was completely flattened by the hand of the Soviets, similar to some other production facilities in Germany. Demolition had been completed by the end of 1947. Following that, the area remained silent for more than a decade.

By the early 1960s, with the Cold War and rearmament in full swing, the the Nationale Volksarmee, or NVA – the short name of the Armed Forces of the GDR – had been long established as an ally of the Red Army. The latter was physically present in Germany with a huge number of troops and war material, having taken over many of the former German bases from WWII (see here or here for instance). However, the GDR clearly had its own Armed Forces, which actually could count on high-quality war material, typically either manufactured in Germany or supplied by the USSR. More and more locations – especially the most secluded and easy to hide – got surrounded by fences, and ended under the control of the NVA for many different purposes.

Deployed on the border with the West, and considered a reliable and well-trained partner by the Red Army, the NVA was included in the war plans conceived in Moscow, intended to unfold in the event of an open war with the neighbor NATO Countries. The NVA had two larger military districts, south of Berlin (III) and north of Berlin (V). In case of war, district III would give birth to a 3rd Army of mixed GDR/USSR forces, to quickly push towards the south-west into Federal Germany (heading to Koblenz), and from there to the Atlantic coast, to be reached in a matter of a few days.

The headquarter of the 3rd Army was in the so-called ‘Mosel’ bunker, an underground command facility near the town of Zwickau, today converted for an alternate use and not visible at all.

An alternate control site, which was also primarily involved in drills and training, was built in the area of the former ‘Beech’ installation, and took the name of ‘Bunkeranlage’ (i.e. bunker installation) Kossa-Söllichau. This site was prepared in the years 1976-79, and consisted mainly of 5 large interred bunkers on the same premises, capable of resisting to tactical nuclear blasts, with up-to-date systems for communication, and an ability to replicate war situations, so as to carry out realistic and complicated tactical simulations and drills. The staff was typically of 400.

Similar to the majority of military assets in Germany – and especially within the super-militarized ex-GDR – Kossa was incorporated in the Armed Forces of reunified Germany (1990), but was soon declared surplus, deactivated and handed over for civilian use.

A society of enthusiasts is today running this former facility, keeping it open for visitors on a regular basis. What makes Kossa an exceptional destination for both the general public and the most committed war tourist as well is the great state of conservation of the entire facility. As it can be seen in the following photographs, taken in Summer 2022, inside the bunkers it is possible to see not only the original structure, but most of the original communication systems, paneling, signs, furniture, lamps, toilets, lighting, wallpaper, etc. making the place a very vivid testimony of the Cold War years.

All in all, this is one of the best surviving specimens of bunkerized NVA sites, and definitely worth a visit for a rich in detail full immersion in the military technology and history of the Cold War years.

Sights

A visit to the Kossa site will start walking past the original inner gateway to the bunkerized part of the complex. The original wall going all around the entire military area has been partly removed, allowing to get direct access to the ‘core’ of the installation by car. Traces of the electrified fence running all around this inner part of the complex are still standing. The entrance to a bunker for the guards can be seen in this area, but this cannot be visited.

The core of the complex with the military bunkers is aligned along a single, mostly straight technical road, built with large concrete slabs. The road track today is the same as in the original pre-WWII complex, and for this reason, it was not camouflaged. Other buildings in the complex, an even the connection roads departing from the main one, are painted in camo coat, for deception in case of overflight by plane or satellite.

The ticket office today is hosted in a large technical building by the entrance. In this area there used to be canteens and other services.

Past the entrance to the bunker area, it is possible to visit five bunkers, which will be listed next.

Computer Bunker

Four out of five bunkers (the exception being the intelligence bunker, see later) are built around the same blueprint. They have a single entrance door, deceived under a small wooden hut. Access to the bunker is via a security and decontamination path. At first you see a big camera at the level of your face, and an intercom panel, all for identification. Next follows a sequence of tight doors, at a close distance from one another, producing three small tight compartments.

In case of nuclear/chemical contamination, faced in wartime, in the first compartment you could take an anti-poison kit, EP-68. Exemplars of this are still in place. In the next compartment you had to throw away all your clothes and belongings, which were put through a hatch to the side. In a third small compartment, you found a shower – a central passage in the decontamination process, even in case of exposition to nuclear events.

Through a last tight door, you could finally enter the clean area of the bunker. Here regular toilets and showers can be found, before going down one level, to the technical part.

Back then, there used to be three levels of air sealing. No air sealing, in regular, no-war/no-drill conditions, meant the decontamination procedure was not activated, and the bunker was ventilated with fresh air. In sealing conditions, typically at war but not under direct attack, the bunker was tight closed, and air was pumped from the outside through huge filtering canisters, purpose designed to stop both smoke and other gases, or poisonous chemicals. On the third level of air sealing, corresponding to an emergency condition (e.g. a direct attack), no air was pumped from the outside, and special filters capturing carbon dioxide allowed to carry on for a limited amount of time – reportedly a shorter time than granted by food or water storage.

Filters for the air conditioning system (sealing level 2) and for adsorbing carbon dioxide (sealing level 3) were made in the USSR. Those for carbon dioxide are scattered around the bunkers, and feature a rather vintage Soviet look, with a prominent five pointed star on top. The label carry the assembly year, in most cases the early 1970s.

Once downstairs, you can appreciate the construction of the bunker lower level, based on prefabricated concrete frames. The bunkers in Kossa were capable of resisting blasts typically from smaller tactical devices, and were ranked at the fifth strength level (level ‘E’), the first level being the strongest.

Here a few rooms are still perfectly preserved with computers, of which the most impressive is a mainframe AP-3, working with magnetic tape. The GDR could boast a top-notch electronic industry within the Eastern Bloc, and all consoles and electronics in Kossa bear local labels.

The purpose of the computers, deemed so relevant to create a bunker specifically for them, was the fast elaboration of all information from the war theater. The latter was both local and global, since thanks to the links reaching the site through the intelligence bunker (see later), information of any kind could be elaborated, allowing the constant updating of operation maps, and the monitoring of all war assets. In drills, the computation capacity of the the system allowed to simulate events, thus forming the core of war-game operations.

A small part of the same bunker, a kind of mezzanine, was designed as a small hospital – all exhibits are original here as well.

More items on display in this area include original dosimeters and gear for checking radiation levels – either GDR- or USSR-made. In the connecting corridors are an intercom and an alarm horn – just examples of the perfectly preserved material on display.

Command Bunker

The command bunker shares the general arrangement with the computer bunker. A full anti-chemical/biological warfare suit is displayed by the entrance, ahead of the decontamination facilities. This type of suit should be worn over regular garments, and made for a very uncomfortable, ultra-warm and suffocating top layer, which reportedly caused extreme sweating.

The focus here is a control room, with a large table and an operation map, as well as connections through several lines to the relevant information networks. On one side of the control room are desks for telephone operators. On another, watches and chronographs. Also interesting are two TV-scopes, which allowed to plot useful information especially in case of drills.

Examples of maps for military drills are scattered all around. Since war plans were all variations on the same theme – a quick attack pushing to the west – all corresponding maps feature this type of planned motion, from within the borders of the GDR to the FRG. The name of the drills can be seen clearly stated on the maps – for instance ‘Grenzschicht – 81’ from 1981.

Other rooms on the underground level feature very interesting examples of machinery for translating information to/from paper maps, even physical 3D maps with elevation!

Satellite or spy-plane images of the site are on display as well. The site of Kossa was reportedly not far from the southernmost of the three air corridors reaching West-Berlin from the FRG. However, even though the site was not unknown in the West, its purpose remained largely a guess for the duration of the Cold War – and likely so also for the local civilian population.

Technical Bunker

A major concern in the Cold War was that of the survival of the chain of command in the event of a total nuclear war. This led to the implementation of additional on-site plants, for self-sustained operations in case a nuclear explosion nearby made the area unsuitable for human life, or when links with the surroundings were lost. These plants included primarily power generators, typically large Diesel engines with their fuel tanks, and drinkable water tanks. As seen in the computer bunker, also breathable air was a major concern.

In the technical bunker in Kossa, similar in shape to the previous two, at least two large power generators can still be seen – and smelt… – on the underground level. Several electric parts for replacement are also there. Another room hosts large drinkable water tanks.

An interesting preserved office for a commanding officer still retains its original GDR wallpaper, and additional comfort is provided by a fake wood pavement.

Large electric cabinets take a big room, where instrumentation for radiation measurement is on display nearby.

Other particulars include a dial telephone with a reminder of the quick reaction numbers, including the Volkspolizei – the name of the People’s Police of the GDR, which can be seen on a label!

Intelligence Bunker

The intelligence bunker is way larger than the others in Kossa, and is also more articulated. Access was possible via two bulky metal gates, located at an underground level on the far ends of the bunker, and reached through truck-sized ramps from ground level.

Behind the door, a tunnel of prefabricated concrete allowed to store many vehicles – typically trucks, jeeps and trailers, including vehicles with communication functions.

To the interred back of the tunnel, a human sized hatch gave access to the pressurized, tight area of the bunker. This inner area, completely interred, is surrounded by a concrete case, built by a single pouring to avoid the creation of weak junctions, and such to withstand intense blasts.

Following a tight compartment, with an array of original air-filtering canisters on display, you get access to a long corridor, providing access to some rooms with technical gears for communication. Here communication with different levels of secrecy were managed, accessing all the existing links implemented in the years of construction within the GDR, and between all Countries of the Warsaw Pact and the USSR.

A first room is centered on a large console, with an original teleprinting device still in place – top-notch for the time. Still in use today in some businesses, teleprinting is a very reliable way of communicating, which is also less prone to interception than telephone.

An adjoining room managed contact with three wired systems of communication, working at increasing levels of encryption security, and used for transmitting routine or less-standard orders. These systems included S1 and SAS communication protocols. The corresponding transmitters/receivers – now very rare pieces of machinery – can be seen on display.

Encrypted incoming messages were sent to a special room, where they were translated in human language, before being internally forwarded to the command bunker. Similarly, encryption facilities were all in another room, where outbound communications were made ready for transmission.

An impressive technical room is stacked with communication electronics. The number of components is really high, and reflects a very high performance, achieved by means of top level, but relatively bulky, components from the 1970s.

A room in this bunker is dedicated to the ‘BARS’ system (‘БАРС’ in Russian), a troposphere (i.e. not wired) transmission system within all States in the Warsaw Pact and with the USSR. Beside an indigenous transmission protocol, the system made use of purpose-designed antennas, with easily deployable nodes put on wheeled trucks. An evoking, very interesting map of the fixed nodes of the system, in Russian, can still be seen on a wall. The desks for the operators of the system are just besides.

Another interesting item is the control panel of a micro-wave antenna, installed in Kossa at a shallow underground level, in an area which can still be located, corresponding to an inexplicable grassy lot along the main road in the site. This antenna system was apparently never used, on grounds of energy consumption and potential damages to other systems in the Kossa site.

Back outside, close to the intelligence bunker are an original weather station, placed nearby a radiation detection system – looking like a bell bolted to the ground. Examples of connection roads covered in camo paint can be seen in this area. Along the main road of the site, many ramps give access to semi-interred lots, where technical trucks used to be placed for operations.

An example of these trucks is a Soviet trailer for enemy signal jamming. This is well preserved both inside and outside. The label tells the construction year – 1986.

Museum Bunker

The last visitable bunker is similar in shape to the former three, and has been converted into a collection of items from the history of the old WASAG site, the NVA bunker and the Cold War.

Propaganda items from the GDR enrich this interesting collection, as well as rare photographs from the totally gone ‘Beech’ site originally developed in the Third Reich years. Also on display are detailed designs of the weapons produced here in WWII.

Getting there and Visiting

The Kossa installation can be easily reached by car, roughly 20 miles south of Wittenberg and 30 miles northeast of Leipzig. Exact location here.

The Kossa bunker is professionally managed by a dedicated Society. Their website is here. They speak only German, and the website is in German accordingly. Opening times are published for the season, and are basically in all weekends in the warm season. A synthetic leaflet in English can be obtained. However, the basic notions on this page may also help in getting much of the visit.

Two separate tickets can be purchased, one for a self-guided visit of the computer, technical and museum bunkers, and another for a guided visit of the command and intelligence bunkers. The guided tour is offered only once per day in German, in the early afternoon as of 2022.

A good strategy for a complete visit may be checking in during the morning, visiting the self-guided part, having a packed lunch, and taking the guided tour.

I followed that plan. This meant a stay of roughly five hours. The report on this page was obtained visiting the site together with Dr. Reiner Helling, who offered me a very detailed insight of the Kossa site, before we took the guided tour.

Photography is allowed everywhere. Flash/tripod generally not needed, at least with high-ISO sensors.

Possibly only cash accepted at the ticket counter.

The Cold War in Hungary – Military Collections, Leftovers & More

Many traces of the communist dictatorship can be found in today’s modern and thriving Hungary. The most visited ones, like Memento Park or Terror Haza in capital city Budapest, tell about the inhumane and pervasive aspect of propaganda and political repression. However, the history of this country in the second half of the 20th century is closely bound to the Soviet-backed communist seizure of power, and this has left traces also elsewhere, especially in terms of military leftovers. As a matter of fact, the Soviet Red Army was directly present in Hungary, to keep the status quo and to to be closer to the border with the West in case of an attack – and this of course left traces.

You can find a significant deal of material concerning more urbex-connected destinations in Hungary in another post.

In this one, you will find a mainly pictorial portrait of some of the best known attractions related to the Cold War period in Hungary, as well as some well accessible but less known ones, especially considering the general public visiting from abroad. As usual on this website, a good share of these sites is aviation-themed!

Photographs were taken in August 2020.

Sights

Iron Curtain Museum, Felsocsatar

The Iron Curtain Museum has been created soon after the collapse of the Iron Curtain in 1989 on the sight of a former small sector of the state border between communist Hungary and free Austria.

The site is mainly the result of the effort of a man, Sandor Gojak, a former border guard in the 1960s, who dedicated this permanent exhibition to those who attempted escaping the repressive communist regime in Hungary towards Austria and the West – both those who succeeded and those who did not, hence facing arrest or losing their lives due to the minefields prepared along the border line.

The site features three examples of the border line placed in the area over the years. They are look less impenetrable than those created between Eastern and Western Germany (see this post), yet they were similarly deadly in scope and facts.

The first is basically a simple line of barbed wire with wooden poles, and it was put in place soon after WWII. Mines were placed in close vicinity to the line. After wooden poles started to rot around the mid-1950s, mines were removed, a dangerous job which cost the health of some border guards, who were severely injured due to accidental explosions.

For a short while at that time, the border was free of mines, and about 300’000 people managed to leave the ‘paradise of workers’!

Soon after the anti-communist uprising in 1956, suffocated with violence by the Soviets, the border was further fortified with concrete poles, and the mine strip was increased in width.

Only at the end of the 1960s the mines were removed, after multiple accidents involving Austrian citizens, when the mines slipped into a creek near the border due to a flood, injuring many who touched them incautiously. This time the border security system was strongly potentiated, with the adoption of an electrified system for the immediate detection of proximity, linked to signal collection centers dislocated along the line. This system had been implemented by the USSR on the Pakistani border. Something similar can be found also on the border between Czechoslovakia and West Germany (see here).

The exhibition is completed by an example of a wooden turret, as well as a more modern fence – a specimen of the one put in place in 2015 between today’s Hungary and neighbor Serbia and Croatia, when a wave of migrants from the Middle East swept the Balkans.

The museum is full of vivid testimonies, thanks to the many historical pictures and artifacts on display, and to the fact that the founder is actually the man who runs the museum! – he is totally available to answer your questions.

Getting there and visiting

The museum can be reached here: 47.20376801287036, 16.429799972912328, on the border between Hungary and Austria, not far from Szombathely. The coordinates point to a convenient parking. The site is operated as an open-air museum, with opening times and an entrance fee. Moderate climbing is required, as the museum area is on the slope of a nice hill. Only cash accepted. Visiting may take about 45 minutes. Website here.

Military Park, Zanka

This small military park is a nice and cared for exhibition of Soviet-made weapons, located ahead of a resort which used to be an exclusive destination for vacation on the coast of Lake Balaton.

You can find here a couple of Mil helicopters – including the legendary Mil-24 in all its ‘beauty’! – in the colors of the Hungarian Air Force.

There is a MiG-21, also formerly of the Hungarian Air Force, a T-64 tank, a howitzer, a military snow blower, an amphibious truck and more light trailers.

Perhaps the most striking sight in this collection is the surface-to-air missile (SAM) SA-2, aka S-75 Dvina in the Soviet codification. A rather basic but powerful – and successful – missile from the 1950s, sold by the Soviets to many satellite Countries and clients over the world.

A revolving antenna can be seen on top of a truck. This is an example of the target acquisition antenna for the SA-2 system, code-named Spoon Rest by NATO, and known as P18 in Soviet codification. This radar system had a range of approximately 170 miles, and was an improvement of the previous P12 design. The launch site of SA-2 SAMs was always complemented by a set of antennas, including a Spoon Rest system. Actually, P18 could be coupled with the launch system of more advanced SAMs too.

All items in the collection here are pretty well preserved, making the visit an enjoyable stop along the exploration of the Balaton coastline.

Getting there and moving around

The park can be found here: 46.881838498667996, 17.7098619193198. The site can be visited in 10-30 minutes depending on your level of interest. This is an open-air museum, with ticket and opening times. Website (referral) with some information here.

Komarom Monostor Fort & Soviet Weapons Collection

An incredible, perfectly preserved military fort from the years of the Austrian Empire, Monostor Fort in Komarom can be found on the Danube, marking the border with Slovakia. At the time of construction, the two nations were united in the Austrian Empire, and the fort was erected between 1850-71 as a part of a defense line extending also north in today’s Slovakia.

Despite being extremely interesting for its articulated and complex construction – a brilliant example of military engineering from the time – the fort saw no action in its intended purpose. It was used for training for most of its life, then briefly as a prisoner’s camp in the years of Hitler’s administration, and finally as an immense weapons storage during the Cold War years, when it saw tenancy by the Soviets.

Today, the fort is open as a museum, duly centered on the interesting original construction from the 19th century.

One cellar has been left as it was in Soviet times, when weapons of all sorts were stored here, moved by means of a dedicated short-gauge railway.

In a corner of the immense apron, you can find a small collection of Soviet weapons, mainly anti-tank and anti-aircraft cannons. There are also a couple of truck-transported antennas, including a very effective early warning Flat Face radar, aka P19 Danube according to the soviet classification, as well as a PRW-9 Thin Skin target altitude detection radar. Similar platforms are still in use today, and can be coupled with modern SAM launching systems.

Getting there and moving around

The fort is a major attraction in the area. It features a large parking ahead of the entrance, address: 2900 Komárom Duna-part 1. Visiting is on a self-guided basis, with a short paper guide in English distributed at the entrance, and the visit will be extremely interesting for anybody interested in history, military engineering, etc. – not only Cold-War-minded subjects.

Visiting may take 1.5 hours, due to the size of the fort. The place is also used as a venue for theater performances and concerts, so timetables may vary. Some info in English can be found on this website.

Papa Airbase

Papa is today an active base of the Air Force, hence it cannot be accessed. However, with a short adventure drive along an unpaved road, you may reach a part of the former premises of the base – from Soviet times – now lying outside the perimeter.

There you can find a pretty unique array of old abandoned aircraft of Soviet make, in the colors of the Hungarian Air Force.

They are MiG-21 of many types, and also massive Sukhoi Su-22.

The state of conservation is not so bad – you can find airframes in worse condition in some museums – but some aircraft are missing some parts, possibly due to spare recycling, or vandalism, even though the place is really secluded, and the proximity with privately owned land and a military base is not ideal for vandals and idiot spoilers.

Of course, a few more years without any attention to these birds and little will remain of this improvised fleet. Hopefully, at least a share of this mighty force will find a due place in some museum or collection over the next years.

By the way, the former military area where these planes are sitting was perhaps a place for SAMs, put for protection of the base in the Cold War years.

Getting there and moving around

This is the only item on this post which is not a museum. It’s hard to tell whether these aircraft are lying on private land or not. However, to reach this strange flock of aircraft, you can move with a standard city car to this crossroads: 47.33966571405878, 17.550239693088113.

From here, you need to take north, until you reach this other waypoint: 47.35812676567956, 17.530436267329513. At some point along this path, the road turns unpaved, but the condition is generally manageable. On the latter waypoint you need to turn sharp left. You may notice old concrete posts, from the original soviet fence of the base.

You will finally land here: 47.35812676567956, 17.530436267329513, where you find an asphalted road, in the middle of a former peripheral area of the base. Driving towards the base along this road, you will find the aircraft here: 47.3541655146187, 17.514827811942904.

Visiting is not a long business, cause you should not move around the aircraft, as they are likely on the border of a private lot (fenced). Totally recommended for Cold War aircraft enthusiasts however.

Komo-Sky 51 Air Museum, Dunavarsany

This wonderful military exhibition is the based on the collection of a Hungarian military pilot, Zoltán Néhai Komócsi, nicknamed ‘Komo’, from which came the name of the museum. Unfortunately, the man passed away years ago in a crash. The collection was publicly put on display only more recently.

Items on display include military aircraft and helicopters, military trucks, trucks from the firefighting squad, engines, and more! Some of the exhibit can be boarded, and reportedly some vehicles are still operative.

Most of the exhibits are in very good condition, a few are still awaiting light refurbishment. An old Mil-2 helicopter can be boarded, revealing an old-fashioned cockpit, made more exotic by the Russian inscriptions.

Also an attack Mil-8 helicopter in Hungarian colors can be checked inside. A Mil-24 is undergoing restoration (as of 2020).

The ‘MiG alley’ includes MiG-15, 21 – in various versions – and 23, all in very good condition, refurbished for display.

Also some trucks can be boarded, revealing once more the excellent state of preservation, as well as abundant Russian signs.

To the far end of the collection, an Antonov An-2 utility biplane, an ubiquitous workhorse of the Soviet empire, can be boarded up to the cockpit.

You can sit in the pilot’s seat, getting a nice view from the cockpit of this bird.

Three deployable radar antennas can be seen on their trailers – apparently a not complete P80 Back Net system from the 1960s is the largest one.

Finally, a MiG-21 in the colors of the Hungarian national flag can be boarded. This is extremely interesting, as it provides a look in the cockpit of this high-performance and successful fighter/interceptor from the Cold War years, when ‘high-performance’ implied ‘high-complexity’ analog cockpits!

Getting there and moving around

The museum can be found at these coordinates, 47.292057190313706, 19.029565655926707, corresponding to a convenient parking. The site is about 30 minutes driving south of central Budapest. It is an open-air museum, with timetables and ticket. Information on their website (in Hungarian). Time required for visiting may range between 30 minutes to 1.5 hours for an interested subject, taking all the pictures.

Komo-Sky Bunker, Dunavarsany

A recent addition by the current managers of the Komo-Sky 51 Air Museum is this fully refurbished Soviet bunker, once used for air traffic control. The place is actually in the vicinity of the former Soviet airbase of Tokol, one of the largest in Hungary in its heyday (see this post).

Today the bunker has been partly restored in look, with some rooms changed into ambiances for interactive experiences, including shooting!

Some rooms host interesting collections of artifacts from the everyday life of communist Hungary.

Military memorabilia from the Red Army, with conspicuous Russian writings, are scattered everywhere.

A room of special interest hosts a collection of militaria from the Eastern Bloc, with artifacts ranging from weapons to flight suits, military decorations to aircraft parts. Really something for everybody!

Getting there and moving around

The bunker is a recent (as of 2020) addition to the Komo-Sky 51 Air Museum. No dedicated website available at the time of writing. The place can be reached at the coordinates 47.297663350792774, 19.0351554512774, about 3 minutes driving north of the Air Museum. I visited by invitation of the owner, hence I don’t know about the actual timetable. A website of a hotel nearby – actually on the very same lot of the bunker – is here, with some information on the bunker in Hungarian.

Museum of Military History, House of Terror, Memento Park, Houses of Parliament – Budapest

Budapest is rightly famous for a history spanning many centuries, for its art collections, incredible architectures, thermal baths and many other enjoyable features. However, having been the capital of a communist country in the Eastern Bloc, it also hosted a ‘state security service’, i.e. an agency of the government attempting to control the minds of Hungarian citizens, and keeping everybody’s behavior under strict surveillance. The palace chosen as the seat for this service is named ‘House of Terror’ (‘Terror Haza’ in the local idiom). Here many were kept under arrest, interrogated, and in some instances secretly murdered in the basement.

The place is among the most visited museums in Hungary, and can be found right in the city center. Comprehensibly, no photo is allowed in the most sensitive areas of this sad building. Website here.

Another place of Cold War interest, making for a rather popular touristic attraction, is Memento Park. In this small park about 15 minutes driving south of the city center most of the statues and monuments once adorning the capital’s downtown have been collected and put on display.

Some from older times, celebrating the friendship of the Soviet and Hungarian peoples, are unbearably rhetoric.

Others are more artistically interesting, in the context of official artistic currents authorized by the Communist Party.

Lenin is of course a favorite subject.

By the entrance, Marx, Engels and Lenin are kind of ‘gate guardians’.

In front of the entrance, you can find a reproduction of the base of a statue of Stalin put in place at some point and surviving in pictures, and later dismantled after the death of Stalin. In the basement of the same construction, you can find a weird set of official busts of Lenin and Stalin, as well as a once popular image of Lenin as a child.

Close by, a small deposit of statues still waiting to be put on display can be found. Website here.

A less visited museum covering the military history of Hungary over the ages, but especially the 19th and 20th centuries, can be found right in the old district of Buda. The display is rather classical and didactic, but for more military-minded people, or those interested in the recent history of Hungary, it is for sure worth a stop when visiting uptown. Website here.

Finally, in the gorgeous building of the Houses of Parliament, you can find interesting info about the changes implemented to the architecture of the building during the communist period.

A unique artifact is the big red star once standing on top of the building, emulating the famous ruby stars placed on top of the towers of the Kremlin in Moscow. Website here.

Secrets of a Soviet Airbase, Berekfurdo

This museum is located in the small town of Berekfurdo, in the eastern region of Hungary, just a few minutes from the former airbase of Kunmadaras, which used to be operated by the Soviets in the Cold War era (see this post for the nuclear storage bunker to be found there).

Unfortunately, I could not visit the museum – it is open only rarely, on a very limited timetable. However, in the courtyard you can easily spot a Mil-24 attack helicopter, as well as a MiG-21. Both have been vividly and freshly refurbished – ready for take-off!

Getting there and moving around

The website of the museum provides good information, and the folks there appear pretty reactive in case you are writing to get more info. It is really a pity they have a timetable so limited. The place can be reached at these coordinates: 47.38366735314769, 20.84155882970934. The museum is made of a small hangar and an outside apron. Considering the size, I guess visiting might take about 1 hour.

RepTar Szolnok Aviation Museum, Szolnok

This is probably the ‘official’ aviation museum in Hungary, at least concerning the military field. It is clearly a well-financed endeavor, with a remarkable collection of aircraft from various ages, helicopters, engines and missiles. Most of the aircraft are preserved outside in an open-air exhibition, the oldest ones having found a place inside a modern and well-designed building. Everything on display has been recently refurbished, hence the collection looks fresh and well cared for.

Two aircraft will likely capture your attention in the main hall, namely a Spitfire in the colors of a Polish squadron fighting with the RAF, facing a Bf 109 in German Luftwaffe colors. The two opponents are displayed besides one another, allowing also for a configuration and size comparison.

Not far is the wreck of an Ilyushin Il-2 Sturmovik, built in huge numbers by the USSR over the years of the Great Patriotic War.

Interesting specimens in the inside hangar include a Messerschmitt Me-108 trainer, some Soviet trainers, classic Kamov and Mil helicopters.

A Soviet H-29L semi-active laser homing air-to-ground missile for the Sukhoi Su-22, which the Hungarian Air Force owned and operated, is on display.

A very interesting old analog approach simulator is also presented. It is made of a cabin mock-up and a large model of an airport, with cameras mounted on moving trolleys, likely projecting a magnified image of the ‘terrain’ in the cabin.

You can board a MiG-21, and see the mysterious content of the noses of some fighter aircraft – typically radar antennas of various levels of sophistication.

An array of engines, from WWII up to our days, are on display on the first floor.

Outside you can find a sample list of virtually all popular MiG models, from MiG-15 to MiG-29.

A colorful example of a MiG-21 will sure capture your eye, similarly to a set of Mil-24 attack helicopters, wrapped in incredible liveries!

A MiG-21 has been placed in an enclave resembling an aircraft shelter, an example of the care adopted in designing this top-tier museum. An SA-2 Guideline is on display by the entrance, visible also from the parking.
