Military Collections in Sweden – First Chapter

When visiting the countries of northern Europe as a foreigner today, you may be easily captured by the beautiful landscapes and elegant architectures, as well as the great food options and the generally exceptional hospitality. Actually, a visit to Scandinavia will hardly disappoint, either in the summer or in the cold season. Everywhere looks like an ideal place for having a good time off.

However, digging in the military history of Norway, Denmark, Sweden and Finland, you might be surprised. Actually, since medieval times peaceful mutual relations have been built very slowly over the years in the area, going through centuries of unrest and struggle often culminating in open wars. In the global conflicts brought about starting with Napoleon until the end of the Cold War roughly 190 years later, the Countries around the Baltic sea have been in the center of a theater of operations of their own.

World War II and the Cold War

Looking at WWII and the Cold War era, the roles of Northern-European countries have been significantly different. Denmark, geographically untenable in front of the German enemy, was taken by Hitler’s Third Reich forces almost overnight, with Norway following shortly after. This gave birth to fierce resistance actions, trying to jeopardize the activities of the enemy. Norway was in the focus of much attention by the Western Allies, who tried to land in Narvik, sank battleship Bismarck, bombed the heavy water plant in Vemork, and transited in its arctic seas to feed Stalin’s Soviet Union with much needed supply (see this chapter). Conversely, Finland fought a fierce war against the USSR, ending up as an ally of Germany after the start of Operation Barbarossa, and finally turning against the Wehrmacht on agreement with the USSR, and managing to leave the conflict in 1944 (see this chapter).

Finally, Sweden did not take part to offensive military actions in WWII, managing to keep a neutral role through delicate diplomatic actions. For this neutrality to be credible however, the Country had to be defended, and its border – both on land and along the shoreline – actively guarded. This meant the construction of many forts all along the Baltic coast, to the west, south and east, as well as ground installations along the border with Finland. Similarly, the military tradition of Sweden, that in modern times date at least from the 17th century, when in the Thirty Years War Sweden managed to take a primary role in the balance of powers in Europe, was not discontinued at all. Despite neutrality, traditional manufacturers of fine firearms and shipbuilders were flanked over time by companies making excellent heavy-duty vehicles, armored tanks and aircraft.

In the Cold War period following the end of WWII, Scandinavia got a possibly even more central status, due to its proximity with the USSR and the control it could exercise on the sea accesses of the Soviet Union to the Northern Atlantic. Where Denmark and Norway joined NATO (see this chapter for Norway, this for Denmark), Finland and Sweden kept a neutral role. Once again, Sweden, not entangled in a complicated post-WWII deal with the USSR unlike Finland, could develop the credibility of its neutrality, preparing for defending against the Soviet threat with a build-up of its armed forces, and the development of original and high-tech military solutions, tailored to its territorial and climatic needs, carried out mostly in-house.

Traces in Sweden

The facts of WWII and especially of the Cold War in Sweden have left relevant traces, which are proudly preserved for the public either in world-class exhibitions, sometimes prepared on the very site of former military installations, or in smaller, well-crafted and much detailed collections, often run by groups of exceptionally passionate enthusiasts.

This and the following chapters cover some of them, offering a cut-out of what a visitor interested in military technology and history can find in beautiful Sweden. Photographs were taken in 2024.

Aeroseum – former Säve Air Force Base – Göteborg

Besides making for a testimony to the originality and commitment of Sweden military planners, the air force base of Säve, located about 4 miles north of the major town of Göteborg in South-Western Sweden, is truly a one-of-a-kind example of a Cold War installation. Conceived for anti-blast protection in the early years of the nuclear age, the base was designed to carry out all operations, except take-off and landing, underground. This included aircraft storage and servicing, but also refueling, loading, towing, and lighting the engines in corridors carved down to 100 feet underground in the hard Scandinavian rock!

The project had an anticipation during WWII, when some special aircraft shelters had been obtained on site by drilling the hillside. However, the actual digging of this incredible Cold War underground base was started in 1950, to be inaugurated by the king Gustav VI Adolf in 1955 (even if not totally complete at the time). The base was sized for a crew of 40 men staying underground with 15 aircraft, of the then new type Saab J29 Tunnan (which translates into ‘barrel’).

The plan of the underground facility features multiple accesses from ground level, on the sides of local hills. Entrances are all misaligned, to reduce the potential damage from a hit by a single attacker. The actual access to the descending tunnel driving down is through a colossal concrete sliding door, 2.3 ft thick and weighing 70 tonnes, with a front area such to allow a fully mounted aircraft to transit with sufficient clearance from the walls and ceiling!

Interestingly, the concrete door is preceded outside by a curtain, which together with traffic lights, switch cabinets and cables can still be seen today. This was installed for further protection to prevent the effects of fallout and contamination, in case of a nuclear attack on the base premises. The heavy curtain could be effective in stopping debris and lower-energy contaminated particles from even touching the doors. Soaked in water for cleansing, it could be then potentially re-employed multiple times, in case of a nuclear war scenario with waves of nuclear strikes.

This feature of the base, already pretty unusual, is the first to welcome – and strike! – the visitor. Then the tour takes you inside, for a full exploration of the underground facility beyond the massive concrete doors.

The feeling when accessing the tunnel is really of something huge. A description of the history of the base is offered as a first item through pictures, schemes and original crests. Then the roomy environment of the access tunnel, descending in a bend to the bottom part of the base, is stuffed with a rich collection of aircraft and helicopters in service with the Swedish Air Force, their engines and technical accessories.

The base of Säve was fully completed by 1963, including the fuel supply system which had posed some safety issues in its original design (fuel went down in case of accidental spilling, thus remaining trapped in the deep-end of the base). However, the F9 squadron of the Air Force, home-based in Säve, was disbanded just a few years later, in 1969. This meant that the underground airbase saw active service with the J29 and later the J34, the latter being the Swedish designation of the British Hawker Hunter. After 1969, Säve was home base to the 2nd Helicopter Squadron, and the underground part, hardly of use for rotorcraft, was then employed as a safe storage for non-active aircraft, notably the illustrious Saab J35 Draken, of which 70 (!) were long-term stored inside, with wings dismounted. The base finally ended its military service in 1998. The underground bunker was re-opened later as the Aeroseum museum, where most of the former airbase was turned into a civilian airport, still working today.

Among the aircraft on display in this first descending tunnel are a Saab J29 Tunnan, alongside its De Havilland Ghost jet engine (license-built under the designation RM2 by Svenska Flygmotor, later Volvo Aero, in Sweden). In service between 1948 and 1976 with the Swedish Air Force, the somewhat elusive J29, little known in the West, was a massively produced swept-wing fighter and fighter-bomber, with 661 exemplars manufactured! Austria, another non-NATO country lying on the border with the Soviet bloc, was the only foreign customer for this machine, which in the 1950s formed the backbone of Sweden’s defense force. A modern fighter in many respects, in the same class of the North American F-86 Sabre and of the MiG-15, the J29 was not easy to master for novel pilots, and unfortunately caused many accidental losses, at a time when Sweden was the fourth air force in the world in strength. It was actively employed in the Congo, where Sweden took part within the United Nations contingent in the 1960s.

On display are also the towing truck and generator employed for engine spool up. In a scramble, the aircraft could be towed up by this Volvo truck, directed on an open air apron, from where it could complete its taxi run alone and finally take-off.

Next in line is a Saab J35 Draken (meaning ‘dragon’), an iconic and successful supersonic fighter/interceptor from Sweden, first flown in 1955 and entering service in 1960, manufactured in 615 exemplars and not less than 10 variants. Besides the Swedish Air Force it was adopted by the foreign Air Forces of Denmark, Finland, and again Austria, the last to withdraw it from service in 2005! This Mach 2 capable machine, with a double-delta wing planform, was propelled by a slightly modified Rolls-Royce Avon engine (manufactured by Svenska Flygmotor as RM6). An original design from the Swedish school, among the features making it so versatile were provision for a two-seats airframe, as well as a general plant simplicity and undercarriage sturdiness, which together with a stopping parachute allowed its deployment from the wartime landing strips.

The latter were obtained in Sweden from the quick conversion of short sections of straight roads in the highway system, creating a network of so-called krigsflygbaser (‘war air bases’), in a defense plan called Bas 60 and later Bas 90. A solution to be found also in the Federal Republic of Germany in the Cold War years, this could greatly enhance the chance of survival of the air force following enemy strike on major air bases, through force dispersal. Yet not all aircraft can safely operate from similar airstrips. Swedish aircraft take this ability into account from the design phase, yielding dependable aircraft, capable of operations in far-from-ideal conditions.

Despite featuring a double, fixed-geometry and comparatively small air intake, the aircraft is single-engined. Underneath the fuselage, this aircraft features a ram air turbine (RAT), for powering the aircraft systems through kinetic energy in the airflow, in case of an engine shut-off in flight.

To the back of this exemplar of the Draken model is a Saab J37 Viggen (which is the name of a local species of duck). Another great example of an original design from Sweden, the J37 is an attack aircraft built in a canard configuration, and like its predecessor capable of short take-off and landing from road runways. Made in mode than 300 exemplars and employed uniquely by Sweden, it was in service between 1971 and 2007. Quite difficult to see out of Sweden, at the time of its introduction it was arguably the most advanced aircraft design to date, in terms of aerodynamic study, avionic suite and attack potential.

Developed in a number of variants for several roles, the exemplar on display features a number of payloads, to be attached to the underwing pylons or under the fuselage, also thanks to the good clearance from ground offered by the tall undercarriage (not to be found on the Draken). Differently from its Saab predecessors, the J37 was powered by a Volvo RM8, based on the American Pratt & Whitney JT8D turbojet, instead of a British engine.

Close to the Viggen, on display is a Saab car employed for friction test on the runway. This was rather widespread in airport facilities in Sweden. Vehicles with similar function can still be found everywhere in the world, especially in countries where runways are subject to icing.

Next in the line is the Saab JAS 39 Gripen, the most current evolution of the Saab dynasty of attack aircraft. Currently manufactured in more than 300 exemplars and exported to several countries, this machine is another original design from Sweden which is also a post-Cold War commercial success. A canard design like the Viggen, this model was introduced in the late 1980s, and it has been updated over the years as an air superiority platform, with a good mix of performance and efficacy, dependability and economical efficiency. Based on the Volvo RM12, derived from the American General Electric F404, it is currently in service. The aircraft on display is the oldest surviving.

Before reaching to the bottom, in one of the recesses along the corridor, photos from the construction phase of the bunker base, its inauguration and the years of operation can be checked out.

Also mentioned in the exhibition is the peculiar chapter of the Swedish nuclear program. The latter was envisioned in the early nuclear age following WWII, and it took shape especially in the 1950s and early 1960s. Besides facilities for the making of what was needed for fueling and managing a nuclear deterrent, on the aviation side Saab was tasked with dedicated projects for a delivery aircraft for nuclear ordnance, to flank the Saab J32 Lansen intended as an interim platform in that role. Project A 36, for an aircraft featuring a Viggen-like fuselage but no canard, and with an unusual overhead layout of the engine similar to the North American F-107, was in the pipeline when the government started to face increasing contrast from the public opinion concerning the entire national nuclear program, which was eventually cancelled in 1968.

Looking at the structure of the tunnel, left mostly untouched from the days of operation, the original wiring and piping for various systems – electrical, ventilation, etc. – can still be seen. The tunnel is also interspersed with frames, where light fire-proof doors could be lowered in case of an accidental fire. They could seal segments of the tunnel, which could then be flooded with fire-suppressing foam.

Approaching the bottom of the descending tunnel, it is possible to find a group of helicopters, in service in Sweden mostly for rescue operations, like an ubiquitous US-made Piasecki H-21 (the ‘Flying banana’), a Sud Aviation Allouette 2, an Agusta-Bell 402 and a Bell 206, the latter employed in polar missions from icebreaker Ymen. An Eurocopter Super Puma and a MBB Bo 105 come from the Swedish military, the latter reportedly having been prepared in a special anti-tank version, but never pressed into service.

Once on the bottom level, you can explore the halls, which are all interconnected, forming a network with a plant similar to a double ‘H’. On the crossing of two halls, you can spot the big round turntables, employed to turn the aircraft when towing them from storage to the base of the ramps going up. There are actually two of these ramps, one is that employed for access by visitors, the other is currently only visible from the bottom level, and off limits (employed for museum service). Its access can be found to the opposite side of the bottom level upon entering.

You can find several aircraft and exhibits on this level, including some pay-per-use professional flight simulators. An interesting exhibition tells about the organization of the STRIL, an acronym for stridsledning och luftbevakning, forming the backbone of the air defense system of Sweden from the early years of the Cold War on. Among the most unique facilities managed by the system are the krigsflygbaser mentioned above. Some original pictures and scale models tell about the detailed scheme of such bases, which could be activated when conditions required.

It is possible to board examples of both the Draken and Viggen models. The latter is presented with the engine dismounted from the airframe, and with many examples of war load either hanging from the wing pylons, or lying underneath. The number of options is really big, witnessing the versatility of the Viggen as an airborne platform.

The cockpit of the Viggen has evolved over time. The one you can see is fully analog. Close by is also the RM8 jet engine of the Viggen, with the afterburner pipe installed – a pretty long assembly! Also a trailer for storing and transporting jet engines is on display.

One of the Saab Draken exemplars is displayed alongside its engine as well. Interestingly, the afterburner pipe has been separated from the engine core in this case, allowing to check their respective size.

Another interesting item on display in this area, alongside a Bell 47 helicopter with its distinctive bubble canopy, is a Saab J32 Lansen. Primarily built as a fighter and entering service in the 1950s, the career of the Lansen stretched to the 1990s, and saw it employed in several roles, including as a trainer. Interestingly, the study for a dedicated engine – the STAL Dovern – was started alongside with that for the airframe, as typical to other military programs especially in the US. The engine, which reached the flight testing phase, is displayed alongside the aircraft. It represents one of the few projects of the Swedish company STAL for aviation. The company has been for long a primary manufacturer of turbines for electric power plants, started in the early 20th century on the remarkable Ljungström design (the homonym brothers actually founded STAL). In the end, the Lansen employed the British Rolls-Royce Avon.

A well-stuffed display is that of on-board radar equipment employed on the SAAB aircraft in service with the Swedish Air Force.

Among the many design and procurement programs of the Swedish military, special attention was given to missiles. The Robot 08 A, an anti-ship cruise missile employed on destroyers and from coastal batteries in Sweden, was the result of a collaborative program with the French. After a boost phase employing rockets, the efficient small jet engine employed for thrust in cruise (a Turbomeca Marbore) allowed the missile to travel at transonic speed, delivering a warhead up to 100 nautical miles away from the launch site. Navigation was through radio control, and homing on target was radar-assisted.

A real work-horse both in the US and abroad (see this post), a Cessna 337 Skymaster in service with the Coast Guard of Sweden can be found in apparently pristine conditions.

A wing of the museum is dedicated to the collection of the Aviation Veteran Society of Göteborg. Among their many interesting projects is the restoration of classic models, often times unique exemplars from an age prior to the introduction of jets. Each of the aircraft on display in their collection, which is always evolving, has a story to tell. For example, one of them, a British De Havilland Gipsy Moth, was employed by his owner (the Swede Gösta Fraenkel) in the 1930s for an experimental treatment of whooping cough, an infectious disease typically developing in children. The pilot took infected people on board the open-cockpit biplane, allowing cold, dry and clean air to ram into their respiratory channels and lungs for some minutes while flying at a sufficient altitude. Apparently, this treatment accelerated recovery in a percentage of cases. Another aircraft in this area is a SAAB 91A Safir. The ‘A’ version is the original and oldest of this light basic trainer and multipurpose aircraft, dating back to the 1940s, and a good commercial success for Sweden.

Another rich collection is based on an impressive archive of Cold War files documenting many Soviet activities in the territory of the German Democratic Republic. This exhibition (a topic often touched on this website, see for instance here and here) is especially interesting for its completeness and for the level of detail – most files show photographs and numerical data.

A nice array of models, often portraying in dioramas scenes from the real aviation history of Sweden or the region of the Baltic sea, is aligned along a wall. Among them, you can see the first ever defection of a MiG to the West on the Danish island of Bornholm (see this post), as well as the grounding of a Douglas DC-3 in Swedish markings by a MiG-15 which had taken off from Estonia (at that time within the borders of the Soviet Union). That DC-3 has been savaged from the bottom of the Baltic Sea years later, and it is now on display at the museum of the Swedish Air Force in Linköping.

Even if you don’t need it, you should take a detour to the toilet, to access an original corridor and have a look to two full-scale reconstructions of STRIL command centers.

Back outside, you can climb uphill to check out a few additional military vehicles on display, including an exemplar of the highly-succesful line of bi-modular track vehicles called Bandvagn, made by the Swedish company Hägglunds in tons of variants and for different roles. Basically unstoppable on any terrain (and actually working in shallow waters as well), this highly versatile machine is here displayed in a Swedish Army camo paint. Also on display is a rather rare moving lounge, a vehicle for easing boarding operation on larger aircraft. Made by Chrysler in the US (and reportedly employed at Dulles Airport in Washington, D.C., back then), this exemplar was in use at Göteborg Landsvetter airport, before the terminal was re-designed for a better management of passenger traffic.

From the hilltop, you may get a vantage view of the airfield, now the general aviation airport of Säve.

Getting there and visiting

The exact address of Aeroseum is Nya Bergets Väg 50, 41746 Göteborg, Sweden. The location is easily reachable along Hisingsleden, taking north from Göteborg, and connecting some of the premises of the huge Volvo factory quartered north of town. From the crossing with Flygflottilijens Väg (where a bus stop is), it is a .4 miles stretch to the museum’s gate. Huge parking on site. Visiting for technically-minded people with an interest for aviation can easily take 3 hours (4 in my case), checking out all the nice exhibits. There is a self-service restaurant at the bottom of the bunker, as well as a nice shop. Entertaining activities for the kids are on the menu as well.

Together with the Air Force Museum in Linköping, this is possibly one of the top air museums in Sweden, well worth a dedicated trip also for the special construction where it is located. Website with full information (also in English) here.

Maritiman – Göteborg

Located in downtown Göteborg, this museum has on display a handful of vessels, originally employed in Sweden in either civilian or military roles. The most sizable of them, the destroyer Småland (J19), is also an illustrious witness of the Cold War, and a lone survivor of the Royal Swedish Navy of that era. She was built by Eriksbergs shipbuilding company in Göteborg, a now defunct primary player in the Swedish naval history, and it saw service between 1956 and 1979 together with the only sister ship Halland, which gave name to the class.

The neutrality of Sweden for the Navy meant that the fleet of the kingdom was developed with self-defense in mind. At the end of WWII, two cruisers were laid down, Tre Kronor and Göta Lejon, which were the largest vessels ever to see service in Sweden. In the 1950s the shipbuilding effort saw the completion of the new destroyers Halland and Småland, which went operating alongside many more destroyer units over the 1950s and 1960s. All these four ships however were the pinnacle of shipbuilding in Sweden in terms tonnage. By the end of the 1950s the last four destroyers of the Östergötland class (lighter than Halland class) had been put into service, and manufacture of either cruisers or destroyers ceased altogether. By the end of the 1960s, the two cruisers were stricken off, and over the 1970s and 1980s many of the destroyers followed. In the high-tech late era of the Cold War, Sweden opted for a larger number of lighter surface ships, in particular corvettes and torpedo boats. The former are represented today by the highly effective Visby class, which constitutes the backbone of the Royal Swedish Navy today.

Of the historical cruiser and destroyer fleet of the Swedish Navy, the Småland is the only surviving unit. In the Maritiman museum, it is possible to board and thoroughly explore this vessel. Among the distinctive construction features, the castle structure runs all along the ship, allowing the crew to operate while keeping inside, so as to avoid exposition to fallout radiation in a nuclear war scenario. Provision for cleaning the outer decks was made with a pressurized water system, running around the castle. Furthermore, material was steel and iron, instead of aluminum, sometimes employed in shipbuilding for saving weight, but more prone to fire damage than heavier steel. The crew was of 250-290 men. The ship went through three modernization programs, and included three fire direction facilities in the castle.

The heavier gun armament of the destroyer is composed of two turrets (one at bow, one at stern) with two 120 mm guns each, and a bow turret with two 57 mm cannon. Additionally, six 40 mm single-barrel anti-aircraft cannons on revolving turrets are placed along the sides of the ship. All guns were made by Bofors in Sweden.

A single 120 mm gun turret was manned by seven men, and could fire 42 rounds per minute, with a range of roughly 12 nautical miles. It could be employed for targeting other ships, aircraft or land installations.

On the side of the 120 mm turrets you can see flare rockets with super intense illuminating power, which were employed for fire direction at night. Fire direction systems evolved over the years, but the task was mainly performed in the castle structure.

The 57 mm gun turret was designed for anti-aircraft operations, with a range of up to 4,000 m, which was roughly 25-30% more than the standard 40 mm anti-aircraft guns. Fire direction was from the castle deck or locally by the designated gunner.

For anti-submarine war operations, Småland has revolving torpedo tubes on the deck, for the Torped 61 torpedo series, a highly-successful design from Sweden, employed also by foreign customers (see this post).

Additionally, to the bow are two racks of launchers for four anti-submarine rockets each. An example of the body of a Bofors 375 mm anti-submarine rocket is on display beside the rocket launchers. It took 40 seconds to reload one launcher. Fire direction and timing was performed from inside the sonar room, or from a control station beneath the launchers.

The ship could carry out mine laying operations. To the stern of the ship some sea mines are on display on the rail employed for launching them outboard.

The Småland could manage helicopter landings on its deck, and it had the ability to launch anti-shipping cruise missiles. This rather innovative solution for the time was based on the Robot 08 platform (see also the Aeroseum exhibition here in this chapter). Two of them could be carried on the launching pad, where further missiles were stored under deck, and a special incline was employed to take them to the outer deck level for launch. Launch was managed with a dedicated fire control computer.

The Småland could operate as a flotilla capital ship, thus navigation and communication systems were particularly modern and capable on this ship, for the time. Digital computers, with pre-defined communications which could be issued at quick pace, are part of the scenery on the top decks of the castle structure.

The crew compartments, even those for higher-ranking staff, and many technical rooms are as cramped as usual on military ships, not so far from their WWII predecessors.

On top of the castle, the command deck can be found, and from here you can get also a nice view of the town of Göteborg.

Among the most interesting parts, is the engine and power supply area. The Småland was pushed by two independent boiler/turbine systems, which gave power to two propellers. Top speed was 37 knots, and at that speed the ship employed 420 liters of fuel per minute!

The engines required 16 men for operations initially, working close to the hot ducts and parts of the engine at extreme noise level. At a later stage, control rooms were installed in the engine compartments, allowing to reduce the workload and increase comfort to a reasonable level. Filtering and shielding was installed on the air intake system, to reduce the effect of nuclear fallout ingestion by the combustion system.

This area can be toured extensively, unveiling many narrow passages and showing the complex structure of the energy plant, producing power for motion and for all the other onboard systems.

Another highlight of the Maritiman is the Draken class submarine Nordkaparen (Nor, in the registry). The six ships of this class were manufactured in the early 1960s, Nordkaparen (laid down by Kockums at Malmö) entering service in 1962, to be stricken off in 1988. The Royal Swedish Navy has always invested much in its submarine fleet, especially along the entire span of the Cold War, with more than 20 units manufactured post-WWII and before 1989. New models have been introduced after the end of the Soviet Union and the Cold War, and currently four modern units are in service.

The Draken class, propelled by Diesel-electric propulsion, was introduced as an improvement of the older Hajen class, with a single slow rotating propeller instead of two, and a modified stern part and control surfaces. With an operative depth of 150 m and manned by 36 men, it was capable of a top speed of 22 knots submerged.

At the Maritiman it is possible to board the Nordkaparen from the stern hatch, and have a complete tour of its well preserved interiors, coming out from the hatch to the bow.

The rear compartment with the electric motors and a sleeping area for the crew is relatively roomy. Conversely, the center section of the submarine allows only a narrow passage between the Diesel engines, with round tight doors which require some body flexibility to go through!

The navigation deck and the cockpit are again somewhat roomier than their WWII counterparts, similar to the forward compartment, with a reasonable area for the crew.

A unique feature of this design is the revolving rack for storing the torpedoes. Torpedo tubes are four, and all placed to the bow of the ship. The revolving rack, resembling that of a giant revolver, hosts eight torpedoes. It is itself loaded from the back, and it can pivot around its axis pushed by a motor, putting a torpedo in the revolver at the level of the firing tube to be reloaded, thus allowing a faster recharging of any firing tube.

Another military boat from the Cold War years on display is the patrol boat Hugin (P151). A fleet of many, lighter vessels was preferred by military planners in Sweden to one of heavier and more expensive ships with greater firepower, especially towards the last decades of the Cold War. Hugin was the first of her class, and it was manufactured in Norway (Bergen Mekaniske Verksted). Sixteen units of this class were in service in the 1980s with the Royal Swedish Navy.

The boat features a steel hull, and is pushed by two 20-cylinders MB518D Diesel engines made by MTU, delivering a power of 3,500 hp each, and giving this boat a top speed of 39 knots. The crew of twenty men could operate for more days in a row on board the ship. This versatile fast boat was armed with inertial-guided and IR-homed anti-shipping missiles (type Robot 12 Mk 2, made in Sweden), depth charges and ASW-600 Elma grenades (made by SAAB in Sweden) for anti-submarine warfare, and sea mines for mine laying missions.

Additionally, the boat has a single Bofors 57 mm cannon for anti-aircraft gunnery. One of the versions of the Arte fire control system made by Philips was installed on the ship, allowing to engage more targets simultaneously.

The Maritiman has on display a number of other boats, covering a range of uses and a big part of the storyline of shipbuilding in Sweden. Among them are fire-fighting vessels, tugboats, as well passenger commuters.

Getting there and visiting

A top attraction of Göteborg, the Maritiman museum can be reached with a nice walk from the historical city center, simply reaching the water bank from it. The museum will be very entertaining for children, but it has even more to tell to technically minded people. Many detailed descriptions in multiple languages all along the visiting path allow to get much from your visit. Furthermore, the majority of the compartments are open or visible on the Småland ship, all on the Nordkaparen, allowing to fully explore these vessels or look into the many technical rooms. A thorough visit may take about 2-3 hours or more, depending on your level of interest.

The exact address is Packhusplatsen 12, 411 13 Göteborg. Parking options nearby (public at a fee). Website with full access information (also in English) here.

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

The БАРС system – The tropospheric network of the Warsaw Pact

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

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

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

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

The Wollenberg site – Bunker 301 ‘Tushurka’

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

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

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

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

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

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

Sights

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Getting there & Visiting

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

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

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

Base Tuono – Cold War Surface-To-Air Missiles in Italy

Just like West Germany, post-WWII Italy found itself on the border with a communist dictatorship, Marshal Tito’s Yugoslavia. Even though Tito and the government of the USSR were never close friends, from the viewpoint of the western alliances Yugoslavia represented a potential threat.

This mistrust was also a result of the aggressive policy Yugoslavia had adopted against Italy after WWII, imposing the cession of a piece of traditionally Italian territory in the northeast part of the country as a war compensation. This had triggered a significant migration of the local population, who was trying to escape from communism to mainland Italy and abroad. This added to the bitterness of the Italian-Yugoslavian relationship, to the point that the new border was not formally settled until the 1970s.

Italy was among the founding members of anti-communist NATO in 1949. This meant the chance to take part in a coordinated defense effort against the eastern bloc. Among the tangible results of this cooperation was the adoption of American war material, including aircraft and, as soon as they became a reliable war asset, missiles.

Considering air defense, besides a number of manned aircraft, the airspace of western Europe was protected by two defensive lines of surface-to-air missiles (SAM) extending roughly from the North Sea to the area around Venice on the Mediterranean. This was studied especially to counteract bombing raids carried out by a great number of enemy bombers simultaneously attacking from the east. This huge defense system was based on the US-designed Nike and Hawk missile platforms, and deployment started in the late 1950s.

SAM installations in Italy comprised the low to intermediate altitude Hawks, with a quick reaction capacity against low-level intruders. These were managed by the local Army. High altitude Nike-Ajax and later Nike-Hercules missiles were operated by the Italian Air Force against high-altitude targets, typically bombers. New dedicated groups were established since 1959, trained in the US to work with the new missile platform. At its height, the Nike force in Italy counted on 16 such groups, apparently corresponding to as many launch bases.

Concerning the effectiveness of the Nike defense line, it soon became obsolete, in the sense that a significant part of the strategic deterrent was transferred to ICBMs by both the NATO countries and the USSR. As a result, SAM defensive lines conceived against aircraft intrusion and low-level attacks would turn out more useful than the high-altitude and high-yield Nike-Hercules. As a matter of fact, all Nike platforms were deactivated in Italy and everywhere in Europe by the early 1980s, well before the end of communism in Europe.

Following deactivation, most bases, stripped of all hardware of any value, were simply locked up and abandoned. In Germany very few traces of this extensive system remain to this day (see this post). Together with the US, Italy is possibly the only country where this fragment of military history is documented through the active preservation of one of the former SAM launch bases.

The Nike-Hercules base preserved in Italy is called ‘Base Tuono’ – ‘tuono’ meaning ‘thunder’ in Italian language – and was operated between 1966 and 1977. It is in a gorgeous mountainous setting in the northeastern Alps, about an hour from the little town of Trento. After years of disrepair, a part of it has been refurbished with original material and opened as a beautiful, partly open-air museum, where you can get a lively impression of how the base would have looked like in the years of operations.

The following photographs are from a visit to ‘Base Tuono’ in Autumn 2018.

Sights

Nike batteries were composed of two connected but geographically separated areas, an integrated fire control area (IFC) and a launch control area (LCA). In the first resided the electronic aiming part, comprising all the antennas and electronic gear necessary to collimate the target, compute the expected kill point of the missile, and to track and guide the missile to that point. The launch area was composed of an array of three flat concrete pads, each supplied with a hangar for storing the missiles, gantries for putting typically three missiles at a time (per pad) in launch position, and a concrete shelter to oversee and trigger the launch sequence. An extensive description of the Nike SAM system can be found on this excellent dedicated resource website.

Due to the features of the radar guidance system, the IFC had to stay in line of sight from the LCA, and at a higher – but not excessively higher – elevation. At ‘Base Tuono’, due to the mountainous setting, the two areas are not far, yet they are not easily accessible from one another. Furthermore, what remains today of the former base is all concentrated in the launch area. One of the three original pads – ‘Alpha’ – has been preserved, where the other two – ‘Bravo’ and ‘Charlie’ – and other ancillary buildings as well, have been completely demolished, and a water basin can be found in their place. All installations and housing in the former control area on top of a local peak – Mount Toraro – have been wiped out, but you can get an impression of the original plan of this part of the base walking around on your own.

Launch Control Area

The launch pad ‘Alpha’ is the focus of the museum. Approaching from the parking, which is located close to the site of the former barracks and canteen, you can spot from the distance three Nike-Hercules missiles aligned in vertical launch position. A water basin covers a large part of the former base, as you can see from historical pictures. Launch pads ‘Bravo’ and ‘Charlie’ are totally gone, similarly to the original outer fence delimiting the large perimeter of the installation.

Getting closer to the launch pad ‘Alpha’ you can notice an array of radar antennas, which were originally in the IFC area on top of Mount Toraro. The area of the launch pad features a reconstructed inner fence, which was in place around each pad in the original base.

The pad is basically rectangular in shape, with a hangar on one side, a protection rim and the launch control bunker on two opposing sides and a free side where today you can find the ticket office.

Three missiles are placed on top of their launch gantries. The gantries are part of a sophisticated rail system, designed to allow an easy side motion of the missiles from inside the hangar to their respective launch positions outside. The missiles were stored horizontally in the hangar to the far top of the rail on trolleys. When being readied for launch, the trolleys were pushed along the rail to the launch position, where the trolley was joined to the gantry. The missiles were raised to a vertical attitude together with the trolley with the help of a lift, which was a movable part of the gantry.

While the pavement is covered in asphalt, you can see the gantries and the rail system are staying on hard concrete foundations. These are among the few remains you see in the German Nike site covered in this post.

Inside the hangar you can spot a Nike Hercules missile, with lateral cutouts to expose the inner structure. These reveal the four-canister solid-propellant booster stage, which was ignited first and was separated from the bullet-shaped second stage when exhausted. The latter features the warhead, the electromechanical rigs of the guidance system, and a single solid-propellant sustainer rocket engine. The rocket had a range of about 25 miles, and a top speed over Mach 3, making it a really remarkable piece of technology especially compared to the soviet counterparts of the time.

All around the missile in the hangar you can see inner parts of the missile itself and of the ground fire control system as well. There are also panels with the history of the base, and original warning signs and instructions painted on the inner walls of the hangar – and similarly on other walls of the base. These writings are in double language, both in Italian and English. While the base was managed by the Italian Air Force, such installations were integrated in the NATO defense line, so many procedures of the Italian Air Force were in English. Furthermore, US military staff was required on site ‘by design’ in case of operations with nuclear warheads, which the Hercules could optionally carry. Nuclear warheads were never deployed to this base though.

Further items on display around the three missiles on the open apron include an old Nike-Ajax missile, a Lockheed F-104 Starfighter – the Italian Air Force was the last in the world to retire this model from service, as late as 2004 – and two trailers aligned in a row. The trailers are the battery control trailer, or BCT, and the radar control trailer, or RCT. Both trailers were originally in the IFC area of the base, and were operated by the staff responsible for offensive operations. In the days of operation, there was always somebody on duty in the trailers.

The BCT is, roughly speaking, where targets were designated, the kill point computed and the launch sequence triggered. The most notable feature are the two computerized plotting boards used to identify the target and to define the flight trajectory of the missile. The LOPAR detection radar and the identification friend-or-foe (IFF) radar reported information to this trailer, which coordinated the attack.

In the RCT stood the operators of the TTR and TRR radars, which were responsible for keeping trace of the target and for monitoring the missile during the flight towards the designated kill point.

To the back of the two trailers, it is possible to spot the rectangular shapes of the LOPAR radar and of the smaller IFF radar. The two round-shaped antennas are the TTR and TRR radars. In many pictures they are portrayed inside a bulbous cover, conferring them a distinctive spherical shape.

The concrete bunker to the opposite side of the launch pad with respect to the trailers is a protected room for the launch section panel, which is a kind of control panel for triggering the launch sequence of the missiles. The bunker served as a shelter for the operators of the launch section, for remaining on the outside in the vicinity of the missiles during launch operations was extremely dangerous.

During the guided visit, you are given a demonstration of the launch sequence from inside the control room, which is insulated from the outside with double tight doors. The firing procedure was quite complicated. Actually, it was a direct signal traveling along a cable connection from the battery trailer that gave the go to the missiles. Yet there were redundancies for increased safety, and it was possible to trigger the entire launch sequence from within the firing section, in case communication with the BCT was lost. During normal operations, the OK from the operator of the control panel in the bunker had the function of a further go/no go safety layer for the launch.

A trailer with a panel similar to that in the bunker can be found outside. This likely represented a further redundancy, or like the F-104 it is a piece coming from somewhere else.

To the back of the bunker with the fire section panel you can find an original watchtower from a US base in northern Italy, similar to the towers originally in place around the missile base. Close by, there is a nice example of the canisters used to the transport the stages of the Nike-Hercules, as well as the crane used to assemble it. There is also a further example of the second stage of the missile.

Getting there and moving around

The ‘Alpha’ battery of the launch control area is open as a museum, called ‘Base Tuono’. It is located on the road SP143, which departs from Folgaria, a small town about 12 miles south of the regional capital town Trento. You can find clear roadsigns leading to the site from Folgaria.

The museum has opening times, visiting is generally possible on a self-guided basis. Access to the bunker and the trailers is possible only on guided tours. All information on their website (in English). Large free parking about 0.2 miles away from the entrance.

There is much to see for technically minded subjects, but the visit will be surely appealing for children too. I would recommend to allocate at least 45 minutes for the visit, and up to 2 hours if you want to take a guided tour and take all the pictures on your own. The scenery around is gorgeous, so it will be easy to combine this destination with a nature trail or with other tourist destination in the area.

Integrated Fire Control Area

This is where the radars and trailers used to stay, together with barracks and service buildings. It can be found about 2 miles south east direct line of sight from the launch pad, on top of Mount Toraro. Differently from the launch control area, this area has been demolished and sanitized. No buildings remain in place, yet some of the former foundations and platforms to anchor the trailers can still be seen.

Reaching to the top of the peak is interesting to appreciate the view of the launch site from here. Unfortunately, at the time of my visit low clouds obstructed the sight.

Getting there and moving around

Even though the wide original road to reach this part of the base still exists, for some reason access to the top of the mountain is not allowed by car. In order to get to the trailhead from the museum, you can take your car and keep going southeast along the SP143 for about 1.5 miles. As you go ahead, the road will change the name to SP92 on your nav. Soon after the road starts descending, you will find the trailhead to your right, with a horizontal obstacle and a prohibition sign for cars. You may park there. It is likely the trail to the top of Mount Toraro will be on your nav too, for it is basically a normal road. The distance to walk to the top is about 1 mile, along the former service road to the base – covered in asphalt, gently ascending, no risk of any kind.

Hitler’s Mystery Mega-Structures in Central Europe

During the last two years of WWII, the Wehrmacht of Nazi Germany was slowly retreating from the eastern front, pushed back by the mighty blows of the Red Army. The bombing runs carried out by the western Allies from airfields in Britain were systematically hitting most urban centers in mainland Germany and over the territory occupied by the Nazis. It is hard to imagine, but it was in the year 1944, when the destiny of Germany was almost sealed, that industrial production in Hitler’s Third Reich reached an all-time record.

At that time the Germans were desperately short of fuel, raw materials and troops, and their production efforts would not spare them from a complete defeat in 1945. Yet it was in the last stages of the war that some of the most ambitious industrial facilities were designed, built and in some cases made operative before the end of the war.

The driver of the design was in most cases the need to move production lines to secluded and well protected areas, difficult to spot and to destroy through air bombing. As a result, these sites were placed far from urban centers. They were also designed to withstand bombing, by putting them underground, or building them with substantial reinforcement, making large use of one of Nazi Germany’s favorite materials – reinforced concrete.

In this chapter two major sites of this kind are described. One is in southwestern Poland, a region which had been part of the German Empire for long before WWII. The second is in eastern Bayern, today one of Federal Germany’s most prosperous states, close to the border with the Czech Republic. Photographs were taken in late summer 2018.

Project ‘Riese’, Poland

Construction around this cluster of underground sites started in late 1943, and reportedly lasted until the closing stages of WWII, just days before the Soviets entered the region. The name ‘Riese’ means ‘giant’ in German, and it is surely well suited for this complex, which while far from finished is really striking in size. It was actually composed of at least six major construction sites, which in the intention of their designers should have been developed deeper in the mountains, until a link could be established between them forming a formidable network of tunnels and large halls.

Besides the size and historical meaning of these sites, what makes project ‘Riese’ so fascinating is also the actual purpose of this incredible complex is far from established. Three major theories exist in this respect. The complex might have been intended to be an underground industrial city, a kind of Noah’s Ark for the ‘superior race’ embodied by the top-ranking military and governmental staff of the Reich, or a gigantic secret laboratory for innovative technologies.

What is sure is that the construction was carried out by forced labor, mainly by prisoners of Gross-Rosen concentration camp, just a few miles north of the complex. For the scope, the Nazis created a number of satellite camps next to the entrance of the  construction sites. Rather incredibly, only very scant traces of the project remain in the written records of key figures of Nazi Germany – Albert Speer’s personal diary notably reports some millions marks allocated for project ‘Riese’, and at some point after the war he cited the item resulting from the completion of the construction works, whatever its purpose, as sized to be capable of hosting some tens of thousands people.

Today, six construction sites have been discovered, of which two – Osowka and Rzeczka, the most conspicuous – have been opened to the public, whereas the other are visitable basically for speleologists only.

Osowka

The first visitable site is in the town of Osowka. This site is composed of two parts, one underground with access from the side of a hill, the other close to the top of the same hill.

The underground part can be visited only with a guide. The plant of the completed construction features two accesses, and you will be driven in using the first and out using the other. Between the entrances, the site is mainly composed of an array of parallel tunnels pointing towards the mountain, connected by long halls.

Close to the entrance you can spot a concrete guardhouse with loopholes for machine guns. Some wooden structures like in a mine have been put in place to give an idea of the appearance of the working technique at the time of construction.

Most tunnels have been dug but not reinforced with concrete walls, whereas others are almost complete, showing a peculiar two-level design. The lower level features a smaller section, and the top one a taller, round shaped section.

A feature of the ‘Riese’ complex is a special technique for building the inner concrete coat of the rocky tunnels, producing the distinctive ‘church-ceiling-like’ appearance of some of the halls, with a round shape and frames close to one another.

The Osowka site features also a collection of smaller artifacts, collected from the ground and dating from the construction years, i.e. from late WWII.

Life-size silhouettes of some WWII tanks are on display, to show how the size of these items was totally compatible with the size of the tunnels, in support of a potential use of the site for weapon manufacture.

The outside part, which can be accessed freely, is the most mysterious. At the base of the trail leading uphill you can spot a strange concrete platform, with provision for – possibly – interred pipelines.

Close to the top of the hill you can find a huge concrete platform, with an apparently chaotic ensemble of slots, pipes, handles, stairs and pools. This item has been deemed close in shape to the base of a service building for the valves and pipelines of a power-plant. Theories have flourished in support of the use of this item as a prototype control system for a nuclear power-plant.

The nuclear program of the Nazis, which indeed existed and is even documented to some extent, is shrouded in mystery for what concerns the actual findings obtained during the war. These dark spots are also due to the destruction of most of the hardware connected with the program everywhere in Germany, and with the inherent secret nature of the program itself. No evidence exists of the Osowka site in the public papers about the nuclear studies of the Reich, so the true purpose of this object is likely to remain an unsolved riddle.

Close by this platform, you can find an original concrete building, part of the same construction plan. It is pretty long, with large windows, and likely intended for troops or technical staff.

Rzeczka

Compared to Osowka, this site is more centered on the inside part. Again, there are two entrances, close by a creek on the side of a hill, providing access to a network of tunnels. Similar to Osowka, close by the entrance you can find guard-houses in concrete. These were built soon, possibly for keeping a watch on the forced workers.

The construction works in Rzeczka were less advanced than those in Osowka. Yet thanks to the lack of the concrete coat, you can appreciate the size of the tunnels, some of which are really tall.

There are small collections of artifacts found in the tunnels, and an original concrete room offers a description of all discovered sites of the ‘Riese’ project.

A 1:1 copy of a V-1 German flying bomb has been placed in one of the tunnels, to show the compatibility of the size of this weapon with the tunnel. Such weapons were reportedly assembled in underground facilities elsewhere in Germany.

Visiting is again possible only with a guide. Some multi-media experiences with sounds, lights and voices are included in the tour, but these are not so impressive for those who don’t understand Polish.

On the outside, you can spot some relics from construction years, including trolleys, and concrete slabs watermarked with symbols of the local construction companies tasked with the practical realization of the site. There is also a copy of a V-2 rocket, operative in the last months of WWII but little effective in changing the fate of Nazi Germany.

Getting there and moving around

As pointed out, the sites connected with project ‘Riese’ are many, but most of them are not visitable unless to specialists and with the help of a speleologist. On the other hand, the two sites of Osowka and Rzeczka are professionally operated as primary tourist attractions. The distance from these two sites is about 20 minutes by car, so you can surely arrange the tour of both sites on the same day, with much spare time in your daily schedule.

At Osowka you can find a large parking and a fully equipped visitor center, where you can book a guided tour, or join a departing one – the only way to get inside. Please note that the number of people admitted on each tour is relatively small, so I would suggest booking at least one day in advance through their website (partly also in English) to be sure to get a place at the time you like. They offer several different tours. The most complete include a visit to a part of the underground site which can only be accessed by boat. This is given only on some days by reservation, and only for groups. The standard tour of the inside is offered several times a day.

The guided may turn out really boring, cause you are provided an audio-guide in English with explanations lasting a couple of minutes for each of the circa ten stops, in face of the Polish-speaking guide talking about 5 minutes per site. You may try to spend your spare time taking good pictures, but even though groups are relatively small, they tend to obstruct the view inside, leaving poor chances for acceptable shots. Furthermore, lighting is not very good, so a tripod would be recommended, except you don’t have the time and chance for undisturbed long poses. Therefore, if you are interested in top-level pictures, you would better arrange a dedicated tour out of the normal touristic offer. Otherwise, you’d better go prepared to a difficult visit.

The outside part of the site is less frequented and more rewarding. It can be reached in about ten minutes following a pretty steep, unpaved trail in the trees. This part is unfenced and unguarded.

The Rzeczka site has only an inside part, which can be visited only on a guided tour. You can join one of the frequent tours they provide even without reservation. There is a small visitor center and plenty of parking space. Similar to Osowka, the guide will speak in Polish, and you are provided an audio-guide in English. The visit lasts less than in the case of Osowka, and the audio-guide explanations are more proportionate to the speech of the Polish-speaking guide, making for a more enjoyable visit. The multi-media experiences are of little relevance for non Polish-speaking people. Outside you can find also some panels with explanations on the history of the site in both Polish and English. Website with some info in English here.

The tunnels in Rzeczka are poorly lighted too, so photographing will be difficult unless with a tripod, but the conditions are not very favorable for operating with a tripod – many people around and short times between stops along the tour.

‘Weingut I’ Aviation Industry Complex, Germany

The giant complex known as ‘Weingut I’, the original codename attributed by the Nazi staff at the time of its design and construction, is the direct result of a plan to relocate all major industrial production lines of the Reich to protected areas, far from the line of the front and from any major urban center. In this particular case, the new factory was intended to shelter the production line of the new Junkers Jumo 004 jet engines for the ‘Schwalbe’ – also known as Messerschmitt Me-262, this was the first jet fighter in the world to be pushed into service, back in 1944.

The huge factory was designed based on a basic module made of a reinforced concrete arch, some 250 ft open, 100 ft tall and 10 to 15 ft thick. This item was to be built on site and partly buried under ground level. Twelve such modules were needed for the complete hangar, with a total intended length of the factory of around 1.200 ft. Of the planned twelve sections, seven were actually built between mid-1944 and the end of the war.

Despite the intended scope was that of hiding the factory to protect it from aerial reconnaissance, due to the size of the construction works the object was reportedly spotted by US aircraft, but not attacked. Actually, the special construction was tested against explosives by the US Army after the war, resulting in the collapse of all modules except one, which is still standing today besides the pretty sizable relics of the others.

The site is not actively guarded, but it is located in a regional nature preserve, so access is through a nice walk in the trees. Once next to the hangar you can find multiple access points.

Close to the main arch, the only one still standing, it is possible to find an explanatory panel in German only. It commemorates also the forced laborers from the nearby concentration camps, who had to take part substantially in the construction works.

Walking under the arch is at your own risk, cause despite the bulky appearance of the structure, smaller pieces of concrete are hanging from from the ceiling. However, a walk inside will give you the most striking impression of the size of the hangar.

Just nearby the remaining module to the west you can find a walkable, half interred bunker, likely with a technical function which is today hard to imagine.

The module still standing today is the westernmost of the hangar, so walking east you will have the chance to step on the roof of the demolished modules. A number of thick iron rods can be spot at ground level.

Walking along the former southern side of the hangar, you can spot a deep well, probably part of the construction strategy. It may have been used to take out the gravel from beneath the base of the arches to lower them to a rest position on more compact ground.

Along the same side you can find a way to walk below the fallen structure. You can also get a view of the edge of one of the modules.

The eastern end of the complex is probably the most hazardous, cause you find an unprotected concrete cliff a good 10 ft high, constituted by the edge of a fallen module.

All in all, the place is a nice example of the undeniable structural design abilities of the German military, really interesting to visit both from a technical viewpoint and as a witness of the utopian visions of the Nazis, which unfortunately cost the lives of many.

Getting there and moving around

Reaching the trail-head is very easy by car. Leaving Mühldorf am Inn for Waldkraiburg along the road St2352, about 0.5 miles south of the crossing with St2550 you will find a sizable gravel factory to your right, preceded by an unpaved road taking west in the trees. You can park on the unpaved road on the northern side of the factory – probably a heir of the original factory built to feed the construction works of the hangar.

From there, you should take the unpaved trail into the trees, closed to vehicle traffic. It is another 0.5 miles to the site, on a flat and easy trail. A quick scan of the Google map will allow you to plan the trip. The place is not remote, cell phones work and you may use a virtual map to get oriented on site. Visiting might take about 2 hours for a very interested subject, including the trip from the parking and back, plus all time needed for pictures .

The Border Forts of Czechoslovakia Against Nazi Germany

The Maginot line – a line of forts running along the French border with Italy, Switzerland, Germany and Belgium – is a widely known example of military engineering from the inter-war period (see this chapter). The adopted construction technique, based on reinforced concrete pillboxes with walls several feet thick, half interred to decrease visibility from above, field cannons and anti-tank defensive guns, witnesses the great consideration given to tanks and aircraft as attack weapons.

Due to the fast movements typical to the new strategy of the German army since the beginning of WWII, the Maginot line is mainly remembered for having not been involved in any major action, and having being largely bypassed. As a matter of fact, the German opted for a bypass also because the line was in place, so it was not as ineffective as it is often thought.

What is possibly even less known is that similar defensive lines were built in earnest in other European countries, before and even during WWII, after the Maginot line had failed to stop the invading German army. The enormous Salpa line, built by Finland against the Soviet Union, was probably the last and most effective to be completed (see this chapter). The Stalin line, prepared by the Soviets against Germany in Belarus, is another example. Another country who invested much in this type of deterrent was Czechoslovakia.

To understand the drivers of the design of the huge line of forts envisaged by the Czechoslovakian government of the mid-1930s, one should take a look at a map of Europe from the time. After the defeat of WWI Germany had managed to keep significant parts of todays Poland. The border between Germany and Poland ran close to Gdansk – aka Danzig in German -, and the province of Lower Silesia with the town of Wroclav – Breslau in German – were undisputed German territory. This means that todays border between the Czech Republic and Poland used to be actually a border between Czechoslovakia and Germany in the years before WWII.

With the turmoil preceding the infamous Munich Agreement and Nazi Germany claiming the right to control ‘Sudetenland’ – a large part of the peripheral territories of todays Czech Republic – in 1937 the Czechoslovakian government quickly started the construction of a huge system of forts to protect the border.

The concept was pretty similar to that of the Maginot line, with extensive underground tunnels to shelter soldiers and ammos, facing to the surface with reinforced concrete bunkers with different purposes, including observation, artillery shelling with field cannons, mutual protection with short range anti-tank cannons, machine guns and grenade-throwing tubes. There were also bunkers for accessing the tunnel system with resupply. About 10’000 light fortifications were actually built, more than 200 heavy fortified positions and a handful of heavy artillery positions.

The geopolitical situation in Europe got worse quickly in 1938, with the annexation of Austria in spring and finally the Munich Agreement, which caused the dissolution of Czechoslovakia. As a result of this internationally approved de facto German invasion, the works on the defense line were halted by the Wehrmacht. A relevant part of the hard construction had been completed, but most of the bunkers were still unarmed or lacked some software – air filters, ammo supplies, everyday items for the troops, etc. – and were not serviceable.

Most of the ironworks, including especially all heavy-metal turrets, were salvaged by the Germans. Some of the cannons found their way to the Atlantic Wall. The most massive concrete bunkers were used to test new weapons. As a result, the majority of the most sizable structures are still today in a partly damaged shape.

Some of the bunkers came to life again in the 1970s, when re-founded Czechoslovakia, that time a satellite country of the USSR living under a repressive and hard communist dictatorship, started a low-paced conversion of some of the structures into nuclear shelters for top ranks of the military and political hierarchies.

Notwithstanding these incidents, todays Czech Republic is duly proud of the significant work which was carried out in the difficult late Thirties. Very much was done for the little time available, and the quality of the design and construction is remarkable. While most of the sites are open only rarely, there are some where you can step inside and enjoy an interesting visit. This chapter covers with photographs and text five larger fortified complexes along this anti-German defensive line, from a two-days visit taken in August 2018.

Map

The following map shows the highlights of each of the five sites listed in this chapter. Please zoom in for greater detail. For the Bouda fort I could not spot and pinpoint on the map all the pillboxes you can easily visit from the outside – this are covered by vegetation.

Stachelberg

The Stachelberg site is located about three miles north of the small city of Trutnov. The fort should have consisted of a main entrance and peripheral shooting positions, some of them linked by underground tunnels, to defend the area of the Giant Mountains. Construction works were terminated much before completion, so the surface bunkers forming the ensemble are actually not connected. Yet the major installation, a bulky infantry positions with provision for anti-tank artillery, provides access to an extensive system of half-prepared tunnels, which gives you a clear picture of the size and capacity of the complex.

The site is open to the public, and the ticket office can be found right inside this huge major bunker. From the outside, the volume of this pillbox is particularly stunning. Also interesting are the anti-tank obstacles, which used to be placed along the border line and between the forts, to trap invading columns in a position where anti-tank guns could be most effective.

This multi-level bunker is also place for a little museum on the fortifications, mainly based on explicative panels and scaled models of weapons and of the entire bunker complex. It covers the history of the fortifications, and explains most technical features of their construction. There are no weapons or other software – they were either not installed before the construction works were stopped, or salvaged by the Germans.

The tunnels can be visited on a guided tour only, starting from inside the main bunker with a descent of several tens of feet along a flight of stairs, originally made at the time of construction. The tunnels unfold on the sides of a major, perfectly straight initial track. Some of the lateral halls, intended to store ammos as well as for sleeping the troops, are very large and close to completion, whereas others are just sketched.

The tunnels were dug in the rock with the help of explosives. The next step in the construction works would have been a layer of concrete from the pavement up to the ceiling of the tunnels. This is present today only close to the entry point, at the bottom of the access stairs.

There are at least other five smaller pillboxes which have been preserved to some extent in the Stachelberg complex. They are accessible with different timetables, and do not provide access to the underground – by design, some of them should have.

One of the pillboxes has been colored in a very bright camouflage. I could not find out whether this used to be the standard, but it looks pretty unusual and not really mimetic… There are also refurbished connecting trenches between the smaller bunkers.

The concrete base of a never built bunker can be found not far from the parking area.

Getting there and moving around

Getting close to the complex is really easy, the area is very scenic and a popular destination skiing, and for nature trail hiking in summer. There is a parking on road N.300 from where the museum-fort can be reached with an almost flat, 0.3 miles track.

The complex can be toured on the outside without restrictions. The main bunker has opening times, and the underground part can be toured only with a guide. The guide speaks Czech, but you are provided a leaflet with explanations in English, upon request. The tour takes about 30 minutes, and is offered on a regular basis, with several entries per day. They warn you about the inside temperature, but I found it pretty easy to bear with normal summer clothes. Website here, but you will need some Google translation to find the info you need.

Voda, Brezinka and Lom

These three forts are actually parts of the same system, built on the eastern end of the town of Nachod-Beloves, the major center in a local valley ending in Poland. Three items in the complex are typically accessible to the public.

The one closest to the town, on the bottom of the valley, is the Voda bunker. This is very convenient to reach, and is basically composed of a preserved typical infantry pillbox with provision for machine guns. The bunker has been painted in a credible camouflage. On one end it is possible to note the damage inflicted by the Germans, when they took out the metal observation turret. This kind of treatment – and damage – can be observed on a great many bunkers of the line.

Inside, the bunker has been turned into a local museum on the armed forces. There were border guards operating in the area, involved in skirmishes before and after the end of the war. The weapons originally intended for the fort are not in place, but there is an interesting collection of weapons, uniforms, motorcycles and other gear from the army corps operating around there over the years.

The Brezinka fort is possibly one of the most famous of the entire defensive line. The reason for that is that it was recently restored to look like it should have looked, if only it was completed back in the late Thirties. In the restoration process, weapons and system parts from other locations in todays Czech Republic were brought to the Brezinka site.

The visit of the interiors is really exceptional, even compared to the forts of the other defensive lines in Europe. The fort really looks like it could be put in operation today!

The first part of the visit of this two-levels artillery bunker will take you downstairs, where you can find the sleeping quarters for the troops with a food storage.

Close by, there are two rooms for the electrical generator and for the ventilation system. Here you can see the electrical compressor, with backup manual handles, and the huge air filters. These are multi-stage filters, where each stage was designed to stop different poisonous components in the air. The system is working, so you are given a demonstration of the compressor – interesting to get an impression of the incredible noise this system produced!

On the same floor there is also a telegraph system, which was used to communicate with other bunkers in the complex in case of failure of the telephone link. This system was capable of transmitting Morse signals to the other pillboxes next to it, projecting the signal into the ground and using it as a medium – there were no cables! This allowed it to work even if a direct electrical link was lost.

The upper floor is even more surprising, cause basically all weapons have been restored to their original positions. The Brezinka bunker featured two main firing chambers. The one pointing uphill features two heavy 7.92 mm machine guns Zbrojovka Brno Mark 1937, a very widespread and reliable weapon, with an operational range of 1’000-2’000 ft at 500-300 rounds per minute. These were used to target infantry movements along the border line, pinpointed by anti-tank obstacles. Fire direction was from the observation turret or via an optical aim system. The latter was extremely precise, but more expensive than the machine gun!

In presence of an impenetrable smoke curtain or at night, an open-loop aiming system could be used. This consisted of a board with a precise sketch of the view of the outside from the firing point, mounted on top of the machine gun. A calibrated needle pointer was used to align the machine gun with respect to the target, by simply pointing the needle on the intended target on the board!

The third machine gun is a light ZB vz. 26, a very popular light 7.92 mm machine gun. This was used for close defense of the fort access. There are also grenade throwing tubes for the same purpose.

The other firing chamber points downhill, and is supplied with a machine gun as in the first chamber, plus the assembly of an anti-tank cannon and another machine gun. The cannon is a 4.7 cm Skoda KPUV vz. 38, with an up to 1-mile range at 35 rounds per minute. It could pierce a 50 mm armor from 0.7 miles apart, and was a very effective weapon. This very cannon was already in place before the German invasion, and was taken by the Wehrmacht to the Atlantic Wall in Norway. It has been returned to its original location in recent times.

There are other two metal-reinforced embrasures in the bunker for other two ZB vz. 26s. On the same floor you can find a kitchenette and toilets for the troops, ammo storages, and two observation turrets. The latter feature a working movable floor, to allow tailoring to the height of the observer. The turrets were fitted with a periscope, and were used to direct fire. They weighed 21 tonnes each, and could withstand direct close fire from anti-tank guns!

Finally, the room of the commander and the telephone room – with an original machine from the Thirties – conclude the tour.

The Lom object, five minutes uphill with respect to the Brezinka fort, is another infantry bunker. It has not been refurbished to the level of Brezinka, but nonetheless it is used to showcase construction pieces, weapons and memorabilia from WWII years. The armored turret was taken away by the Germans.

Between the Brezinka and Lom bunkers you can find a section of anti-tank obstacles. The concrete base used to support them can be spotted in several places here and other sites of the defensive line.

Getting there and moving around

These bunkers, and especially Brezinka, are surely among the most interesting of the kind to visit, considering also their counterparts in France, Finland and Belarus.

The Voda site is easily accessible by car. The Brezinka and Lom bunkers cannot be reached by car. You can park on a street close to the trail-head and take the trail. Unfortunately, the road going uphill, albeit not uneven, is extremely steep and about 1 mile long. You should definitely take this into consideration when planning your excursion, even if you are physically well-trained. Very few beverages are available at the Lom site, which is five minutes farther uphill from Brezinka. Nothing is sold at Brezinka.

It is a pity they didn’t prepare a better access road, cause the site is surely worth a visit, and may appeal to the specialist and to the general public – especially children! – as well.

Only cash is accepted in all these sites. The Brezinka site is accessible only with guided tours. Tours were offered every 20 minutes in late August when I visited. You are given a detailed leaflet in English or German, in case you can’t speak Czech. The guided tour of Brezinka takes about 50 minutes.

The Lom site can be toured in 10 minutes, whereas the Voda bunker is worth a 20-30 minutes self-guided visit. Explanations are partly also in English and other languages in the Voda bunker.

Information on these three forts can be found from this website.

Hanicka

The Hanicka site features an extensive underground tunnel system, actually connecting the main entrance to some major peripheral forts. The ensemble includes one of the few most imposing firing units in the entire defensive line.

But what makes this site even more unique is the fact that, after having fallen into oblivion since the end of WWII, in the 1970s it was selected to be developed into a nuclear-proof governmental bunker – codenamed ‘Kahan’. The ensuing modifications altered greatly the appearance of the entrance bunker, and most of the systems you can see today in the underground part are actually dating from the 1980s.

The works on the conversion were carried out at a slow pace, and were actually not completed before the end of communism in Czechoslovakia, the collapse of the Czechoslovakian federation and the birth of the Czech Republic in the early 1990s. The bunker was soon opened to the public as a unique specimen of military building engineering from both WWII and the Cold War.

The tunnels can be be visited only with a guided tour. The original entrance to the tunnel, modified in the 1980s, is the starting point of the visit. The entrance to the bunker looked totally different before it was developed into a nuclear shelter. The modifications at the level of the entrance included the construction of a soft service building, with room for storages of trucks, armored vehicles and other material.

In the first hall giving access to the tunnels you can find weapons, communication systems, scale models of the site, maps and much more from both the ‘two lives’ of the bunker, in the 1930s and 1980s.

Access it through a thick, typical soviet nuclear-blast-proof gate. Inside, you see the nuclear-proof system allowed to seal a section of the entry tunnel close to the gate. The bunker was designed to allow long-term survival and operations for 300 people also in case of total insulation from the world outside.

A modern energy production system was put in place and can be seen together with water and gasoline tanks. The structure of the bunkers was not altered significantly, but the various systems date clearly from more recently than the Thirties.

There are also extensive sleeping quarters and a medical facility to the far end of the main tunnel, which was built in the side of a hill.

You finally come out in a former infantry bunker, reached climbing upstairs to the top of the hill. Here the embrasures and reinforcing panels of the firing chambers are still in place.

The next part of the visit will take you to some other smaller bunkers, visible only from the outside.

The visit ends in front on the major RS-79a bunker, a top of the line artillery bunker. This was provided with three embrasures for field guns. The size of this installation is really striking. You cannot visit inside this bunker.

It was somewhat damaged by weapons testing by the Germans, and never refurbished. You can see a nuclear-proof door substituting one of the original embrasures.

Back to the parking, it is possible to see from the outside an infantry bunker and examples of anti-tank barriers. This bunker is a rare example of a totally undamaged fort of the line – even the metal turrets are original and have been left in place by the Germans.

Getting there and moving around

The Hanicka complex can be explored outside with no restrictions, but the inside can be toured only with a Czech-speaking guide. They provide you a leaflet in English. The visit lasts about 60 minutes. Info on their website.

The entrance is via the original entrance bunker, modified in the 1980s. Reaching this point from the parking on road N.319 is a bit demanding, cause you need to walk on an unpaved road going uphill with a relevant grade for about 0.7 miles, then you have about another 0.7 miles walking on an easy, flat road. Differently from Brezinka (see above), they have a facility selling food, beverages and souvenirs close to the entrance. It’s a pity they just did not prepare a good road and a parking nearby the entrance.

Anyway, this site has much to offer and the visit is highly recommended, both inside and outside, for children and adults as well.

Bouda

The two nearby forts of Bouda and Hurka share a basically similar construction, and represent possibly the best examples of almost-complete forts in the defensive line. They are articulated around a straight tunnel, mined in the side of a mountain. The section of the tunnel next to the main entrance bunker features a narrow gauge railway, used to transport ammos and various supplies to the storage units inside. Deeper in, there is provision for sleeping quarters for the troops. To the far end of the tunnel you can get access to a group of fortified installations and artillery bunkers.

The Bouda installation can be visited thoroughly. The site is very big but more remote to reach than Hurka. Besides the access bunker, where the ticket office can be found, you can see a specimen of a metal turret. None of the original turrets has been left in this site, all have been salvaged by the Germans.

Soon after the beginning of the tour, you will see the terminal of the narrow gauge railway. The double track goes through a short incline. At the base of the incline the main tunnel starts.

Not far from the entrance you meet slots for sealing doors and related actuation systems. These were installed by the Germans and used to test their reliability and the effectiveness of their weapons on them. They had some cannons installed further in along the tunnel, and shooting on the armored doors they had installed.

The railway turns single-track, until you reach a major storage for weapons with a loading platform. One of the storage chambers has been reused to display a collection of weapons used in the forts and the corresponding armored embrasures.

Further on you visit a group of chambers originally intended to be fitted as sleeping quarters. The dividing walls and metal frames have been demolished at some point – or may be they were never installed – but some of them can be seen, original or reconstructed. In this area there is also a memorial to Czechoslovakian troops.

Further in the tunnel you reach another set of chambers, one of them with pieces of armored constructions and other heavy material from around the site. Then you get access to the stairs leading to a heavy artillery bunker.

What you see here is the cylindrical concrete box where the actuation mechanism and reinforced cupola should have been installed. The size of the construction suggest the total intended size of the field cannon assembly, really big! This should have been very similar to some of the installations in the Maginot line (see this post). There is also a firing chamber for lighter weapons where nothing remains except some metal coating.

The guide will lead you back to the bottom and inside the main tunnel, and ascending along another stairwell you can reach an observation bunker with provision for light weapons. This bunker is in a better shape, and significant traces of the original soft construction are clearly visible.

Damage is due also to weapons testing carried out by the Germans, clearly visible from the outside.

Upon reaching the surface, you will be directed along a walk through the exteriors of the bunkers in the fortress, including the incomplete heavy artillery bunker, with the large concrete pit from visible above.

Finally, you access one of the bunkers, which appears pierced and heavily damaged from the outside. On the inside the firing chamber is fairly well conserved, with the original embrasures for machine guns still in place. The wall is pierced presumably by a shell or mine.

This very bunker was used also for testing high-yield explosives, and as a result of a huge explosion it shifted sideward of a few feet, without collapsing and with no alterations to its general shape – really sturdy! You can clearly appreciate the shift by going down in the stairwell!

You will then return to the main entrance with the ticket office where the visit will finish.

Getting there and moving around

The bunker parking can be found very easily driving north of the road N. 11 between Cervena Voda and Cerkovice. The area is popular for nature trail hiking, and the fort is also a popular attraction. Following the road signs, you will be driven to an observation tower on top of a mountain.

From there, the entrance to the bunker can be reached only by taking a trail which descends along the northwestern side of the mountain. The distance to cover by foot is a good 1.5 miles, so this should be taken into consideration when planning your trip. You have to go uphill on your way back to the parking, so the trail is more demanding when you are leaving. There are signs on every crossing, so you should not get lost. By the way, the walk is really nice, going in the trees with some bird-eye views on this beautiful countryside!

Once at the entrance of the bunker you can find refreshments and souvenirs. The bunker can be visited only with a guide. They are offering three options for the visit, each of them adding something to the other, yielding a difference in time. I took the most complete tour, and it took about 180 minutes.

You are provided jackets for staying inside – even though the temperature is not extremely low, especially if you are wearing technical trekking clothes, which are recommended for the preliminary trail to the entrance. The jackets are dirty, so it’s better to bring one of your own, as they almost force you to have something to cover in!

The tour is offered in Czech, with explanations in English provided on all panels and on a leaflet you can borrow inside. There is a fee for taking pictures, but both this and the entry ticket are rather cheap. Further info on their official website.

Hurka

The Hurka fortress is an installation pretty similar to the Bouda site, at least considering the inside part. After some years of closure following WWII, the Hurka site was converted into an ammunition depot in the 1960s. The modifications inside include some demolition work on the soft walls and frames, so the structure is mainly composed of large vaults.

The tunnels can be visited only with a guide. The visit starts from the original gate of the underground facility, where all supplies could be placed on a narrow-gauge convoy. An external loading platform can be spotted, together with specimens of anti-tank devices and of the reinforced observation turrets.

Inside, an incline leads to the initial part of a long straight tunnel. The exhibitions provide an impressions of an ammo storage, and there are also weapons and armored embrasures from the fort.

An interesting exhibition prepared in one of the halls is about the activities of the agents of the Czechoslovakian government in exile during WWII. This included launching paratroopers over the territory of the former Republic, tasked with establishing contact with dissident anti-Nazi movements, and carrying out high-risk, top-priority missions. A pretty famous mission they were tasked with was the assassination of Reinhard Heydrich, a top-ranking SS, since 1941 responsible for the administration of the annexed territory of todays Czech Republic. A bloodthirsty, feared and hated figure, he died in hospital soon after having being shot in June 1942 in an operation codenamed ‘Anthropoid’. All the spies involved in the operation were later killed, and terrible retaliation actions were taken by the Nazis on the local population. An international movie was produced on this subject in 2016.

You don’t get access to the firing positions from inside, but you can visit them from the outside on your own and with no restrictions.

A pretty rare feature is a ‘top of the line’ artillery bunker, with three shooting embrasures on one side. This bunker is today standing severely damaged from German fire, inflicted during weapon testing. The bunker was actually de-interred by the Nazis to expose its walls, and perforation cannons were tested on it. Among them, the so-called Röchling shells, with a high perforation potential, adopted operationally but used very rarely in action by the Germans.

The other artillery positions are scattered on a grassy area on the side of a hill dominating a local valley. You can see the damages inflicted by fire testing, and the empty boxes of the metal turrets salvaged by the Germans.

Getting there and moving around

The tour of the underground starts from the original access bunker, which can be reached just north of Kraliky on road N.312. Convenient parking outside. The underground can be accessed only with a guide. The ticked office offers also food and beverages. More info on their official website.

The firing positions can be toured on your own. They can be accessed driving about 0.3 miles north along the same N.312 road to the top of the hill, and turning left on an unpaved road. You will soon see a bar with a prohibition sign for cars. You can park nearby on the grass and proceed by foot, you will meet the fortification with an almost flat walk of 0.15 miles. There are signs with multi-language explanations close to each of the bunkers. The place is really nice, and the walk is highly recommended.

Traces of the Cold War in Southwest Germany

Between the end of WWII and the collapse of the USSR in the early Nineties, Germany was caught in the middle of the confrontation between the West and the Soviet bloc. An unnatural and heavily guarded new border was established between the two adversaries, which crossed the extensive territory of todays Germany. Thanks to the presence of American, British and French military forces over the western territory of the Country, and of the Red Army to the east, with the start of the Cold War the German ‘inner border’ became a modern line of the front for this new type of confrontation (see this post).

All armies stationed there benefited from substantial resources poured by the respective governments in the setup of permanent military detachments and infrastructures. The aim for the nations involved was that of having on the spot a credible force, capable of effectively fighting an enemy army – as well as hitting the populations of neighbor Countries – in case a new war was started in Europe. In the end, an open war was never fought, yet for decades it was deemed possible, and in some crisis moments even likely (see this post).

This chapter presents pictures from five Cold-War-themed sites in southwest Germany. Photographs were taken in April 2018, and in the summer of 2020 and 2021.

Sights

With the end of the game for the communist empire and following German reunification, Russian forces withdrew from all bases in Germany – as well as from many other Countries in Europe – and so did the foreign NATO allies, with a very few exceptions. Most former military bases and military infrastructures fell in a state of disrepair, and by the years the majority were either completely wiped out or converted into something else. Nonetheless, especially in the less crowded territories of the former communist East Germany, visible traces remain from the period, in the form of – sometimes immense – abandoned airports and military bases (see this post and links therein).

Comparatively less traces of the once substantial presence of NATO forces are to be found in todays western ‘Länder’ – i.e. administrative regions – which used to be part of West Germany. Yet something of interest for Cold War ‘archaeologists’ can be found also here.

A long chain of anti-aircraft missile batteries was implemented based on the Nike missile system designed in the US, and implemented by the US Army as well as other NATO armies in West Germany. The defensive line was established in the 1950s and updated over the years, running almost parallel to the border with the communist DDR, but located pretty far from it and well within the territory of West Germany. It stretched from the North Sea to the Bodensee, on the border with Switzerland. There are some very extensive references on the web providing a complete description of the Nike defensive barrier both in the US and abroad, a very rich one here (the link should point directly to the German section).

In this chapter you can find some pictures from an exploration of an abandoned Nike Hercules site next to the town of Wurmberg, just out of Pforzheim, between Stuttgart and the French border. It used to be run directly by the US Army.

Intermediate-range ballistic missiles (IRBM) were part of the tactical plans of both the US and the Soviets in Europe. The Pershing platform, based on the homonym theater-level nuclear missile, was deployed in Germany, and placed in the inventory of both the US Army and the West German Luftwaffe. The missile was updated in several instances in the decades of the Cold War, until it was banned by the INF treaty in 1988, agreed upon by the administrations of Gorbachev and Reagan.

Among the strongpoints of the Pershing missile deployment in Europe, a huge warhead deposit was built close to the town of Waldstetten, next to Schwäbisch Gmund in southern Germany. In this chapter you will find photographs from an exploration of this mysterious site.

Furthermore, a nice collection of aircraft from both sides of the Iron Curtain can be found in the southwestern corner of the Country, next to the town of Villingen-Schwenningen – one of the few air museums in this part of Germany. Similarly, the large collections of the military museum in Stammheim, next to the town of Schweinfurt in northwestern Bavaria, and once close to the ‘Inner Border’ with the GDR, has on display substantial specimens from the Cold War era.

Finally, a special feature presented in this chapter is a group of pictures from the former airbase in Giebelstadt, south of Würzburg, Bavaria. Today a privately owned general aviation airport, this former military airbase gained a special historical significance when it was selected for the departure of secret overflights of the communist territory beyond the Iron Curtain, performed with the Lockheed U-2 in the late Fifties, by decision of president Eisenhower.

Nike Missile Battery – Wurmberg

The site in Wurmberg, east of Pforzheim, was actually Battery ‘Delta’ – i.e. the fourth – of the four missile forces managed by the the 3rd Battalion of the 71st Air Defense Artillery (ADA) regiment.

Typical Nike missile batteries were composed of two geographically separated areas. The largest was the ‘Launch area’, with missile storage facilities – sometimes reinforced underground bunkers, sometimes more usual ‘soft’ hangars – and launch pads. The other was the ‘Integrated Fire Control area’ or ‘IFC’, where all antennas and electronic equipment for target detection and missile guidance were placed. Due to the limited speed of motion of the missile guidance antennas, the distance between the launch site and the IFC had to be greater than a threshold, while the elevation of the IFC had to be somewhat above the the launch pads. These technological constraints led the choice of the sites suitable for the installation of the Nike batteries.

The site was deactivated in the Eighties, and both areas were sanitized in more instances, basically demolishing any buildings. The ‘final stage’ of the operation is likely to be underway at the time of my visit, as you can see from the pictures, where piles of gravel and moved land can be spotted all around the launch site.

Surprisingly, a feature that has come to our days virtually without any alteration is the external fence of the launch site, which runs all around the launch area and is still particularly impenetrable. Also the rounds of barbed wire on top are still there.

The exploration of the launch area is pretty straightforward. It is rectangular, basically flat and aligned along an east-western direction. Close to the eastern end,  you meet a flat area with a concrete pavement – now partly demolished – and a curved road nearby. This is where the missiles and warheads were assembled. Nike missiles could mount nuclear warheads, but apparently this was a rarely adopted option.

The next notable item to the west is a water basin, still in a very good shape. There used to be a water system all around the base. Remains of demolished buildings can be spotted around here too.

A mystery electric cable comes out of the ground on a spot. It is noteworthy that the launch area and IFC were connected by an underground cable, but I don’t think this is the one you see in the pics.

This battery had three launch sectors, bearing the little imaginative names of ‘Alpha’, ‘Bravo’ and ‘Charlie’. You can find them in a sequence, walking towards the west end of the site.

The pads of the Alpha sector, while now greatly damaged by the demolition work, are still in place with their metal covers.

There were three launch pads on each sector. The area of each sector appears unnecessarily large, but actually the missile storage hangar used to stay beyond the launch pads, occupying about half the area of each sector. Today these soft constructions have disappeared.

To the west of each sector there is a small bunker, intended for the protection of the troops working around the launch pads, in case of an attack to the battery. These bunkers are not very damaged, so they constitute a very interesting part of the site today.

The protection bunkers have two exits on the two opposite sides – so the Alpha bunker connects the Alpha and Bravo sectors, the Bravo bunker the Bravo and Charlie sectors, while the Charlie bunker connects the Charlie sector to the logistic storage area to the west end of the launch site.

The Alpha bunker is well conserved – except for some spoiling by some idiot writer. There is no camouflage paint coat outside, just some plain green paint, and the walls inside are painted in a bright crimson color. The bunker has two opposite entrances, and two corresponding corridors leading to two massive tight doors, which give access to a central protected room, insulated from the outside.

Writings in English are still there in the central room of bunker Alpha.

The launch sectors Bravo and Charlie are more damaged than Alpha.

The Bravo bunker is camouflaged, and differently from Alpha the walls inside are painted in water green. It is possible to notice how the central room was separated from the rest of the structure for blast insulation, similar to other missile sites (see this post). There is a wide slot at the level of the doors.

Further writings in English and some original linoleum pavement are still perfectly visible.

The Charlie bunker is different from the other two. The facade is wider, it is coated in a camo paint, and bears the name ‘Charlie’ above the eastern door. Inside it is very dark, possibly as a result of a fire. In the insulated room it is possible to see an original air conditioning system.

The three launch sectors are connected to the south by a wide road, from where you can appreciate the extension and state of conservation of the original fence.

The IFC area is located just north of the small town of Wurmberg, on top of a hill. Unfortunately, the former military site has been wiped out and a nothing less than a waste disposal facility has taken its place! Anyway, from this vantage point you can clearly see the launch area, roughly two miles to the west.

Getting there and moving around

Getting to the launch area is very easy. Leave the highway N.8 close to Pforzheim (the exit is 45b Pforzheim-Süd) and take for Pforzheim on Wurmberger Strasse. Take the very first road to the right and park your car there. You will see a gate open since ages and an almost unmaintained road taking straight north and climbing gently uphill. This road will take you to the official gate of the launch area in 0.4 miles. Getting in is probably prohibited, but the area is pretty remote and secluded, and I didn’t see a person around during all my stay.

The site is geographically compact, so touring may take about 2 to 2.5 hours taking all pictures, if you have planned your movements in advance. A tripod is strictly necessary for taking decent pictures inside the very dark bunkers.

The IFC area can be reached going to Wurmberg, leaving the same exit but taking the direction opposite to Pforzheim. You will soon reach central Wurmberg. Cimb along Gollmerstrasse, then along Oschelbronnerstrasse. Where the village ends and the road stops climbing you will see a field to your left and a waste disposal facility to your right – this used to be the area occupied by the IFC area. Looking west you can see the launch area and the taller buildings of Pforzheim further in the distance.

Pershing Warhead Storage Bunkers – Waldstetten

The site in Waldstetten is basically an array of warhead storage bunkers, built between 1954 and 1958 by the US Army. In 1972 these bunkers became a part of a Quick Reaction Alert site, managed by the 1st Battalion of the 41st Field Artillery Regiment, tasked with supplying the nearby storage site of the Pershing missile in Mutlangen, just north of Schwäbisch Gmund. The site saw major action in 1982, when 36 Pershing II missiles were installed in Mutlangen as an answer to the deployment by the USSR of an updated version of the excellent SS-20 Saber IRBM system.

During the Eighties the 1st Bn 41st FA was reformed more than once, until it became 2nd Bn 9th FA in 1986, only to be disbanded in 1991, following the dismantlement of the Pershing system as a consequence of the INF Treaty between the US and USSR.

It should be mentioned that whether the nuclear warheads of the Pershing missile ever made their way to this storage site is a matter of discussion. As a matter of fact, the missiles were in the nearby Mutlangen site, and their installation triggered well documented protests by the usual pacifist folks, who encountered difficulties in understanding the moves of the Reagan administration, which helped with successfully putting an end to the Cold War and to many communist dictatorships in Europe. What the bunkers in the Waldstetten site were used for is not totally evident, and it should be recalled they were built in the Fifties, before the deployment of the Pershing system.

Of the 28 bunkers originally built, 25 exist today while three have been demolished in a landslide. The site is located in the trees along two broad circular roads, once service roads. Today it is in the heart of a natural preserve, and the roads are used by MTBs and hikers, whereas the Mutlangen site has been converted into a solar power plant.

The local administration has prepared a placard with a map and a short history of the place (in German only), which I spotted only by the first bunker you meet climbing uphill along the road approaching the site from north. You can see the placard in the pics below, with the corresponding map. The position indicated with ‘Standort’ on the map is where the placard is. I suggest starting you exploration from there.

About half of the bunkers can be accessed. Except a few, they are basically indistinguishable.

Inside they are empty and very basic in shape, with just one large storage room. Other bunkers are inaccessible, and some have been converted into bat shelters.

A notable bunker is 870 (see the map in the pic), which bears on the front facade graffiti from US troops, probably veterans visiting the place in recent times after it was closed up. Today it is a bat shelter.

In 869 you can find some naive paintings, including one portraying a truck probably dating from the years of operation.

A mystery bunker is 856, which is very different from all others. It has two small entrances, apparently for humans only, and a group of small chambers ahead of the larger storage area. This has no wide entrances, suggesting it was not used for warheads nor anything similar, and a blind room to the back. Unfortunately, this bunker is also covered in indecent graffiti.

Another interesting sight, especially visible to the west of the bunker area, is the original fence of the storage site, with a number of aligned concrete posts and traces of barbed wire. The line of the fence is shown also on the map.

Getting there and moving around

The storage bunkers are located on top of a hill, and some climbing is required to reach the bunker area. The place is not fenced, and there are multiple access points from all directions. I personally parked at the end of Dreifaltigkeitsstrasse in Waldstetten and accessed the site from the west. After touring it, I came back passing by the placard mentioned above. The road is steeper on that side of the hill, but starting from the placard may ease your exploration.

Please note that the on most part of the site the cell phone coverage was very weak, with no access to internet data. I strongly suggest downloading your maps before being on site.

The place is secluded and the bunkers are much overlooked by the locals, who keep on the main track and just cross the area – you will probably move around undisturbed if you walk in and around the bunkers.

Due to some amount of mild hiking required, a complete tour of all bunkers may take about 3 hours, including time for pictures.

Internationales Luftfahrt-Museum – Villingen-Schwenningen

This small air museum is composed of three parts.

The first is a single hangar, stacked with smaller aircraft and a helicopter, plus memorabilia and parts of aircraft of diverse proveniences and ages, including German machines from WWII, and later from both sides of the Iron Curtain.

The main part is a grassy apron with an open air collection. Here you can see aircraft of American make in the colors of the West German Luftwaffe, including an F-86 Sabre and F-104 Starfighter.

British aircraft are represented by an English Electric Canberra and a DeHavilland Vampire of the Swiss Air Force.

Other models from western Countries include an Italian Fiat G-91 reconnaissance aircraft and a German Dornier Alpha Jet trainer.

Models from the Soviet world include an Antonov An-2 biplane, which can also be boarded, and a Yakovlev Yak-18, bearing a post-Soviet Russian flag and registration markings.

Probably the star of the show, a well restored Polish-built MiG-15 is presented in the markings of the Red Army.

The third part of the museum is a series of restoration hangars, where a number of aircraft are being restored, whereas some replicas are being assembled, possibly partly from original parts. These include a Messerschmitt Me-262 Schwalbe, and a Dornier Do-335 Pfiel, of which only one original exemplar exists in Washingtong, DC – definitely a rare sight.

Getting there and moving around

The museum, located on the side of a local touristic airport, is easily reachable in Spittelbronner Weg 78, 78056 Villingen-Schwenningen, just on the eastern border of the beautiful Schwarzwald region. Website with full information here.

The museum in Stammheim, northwestern Bavaria, stands out as one of the largest and best preserved military collections in Germany, especially concerning the two World Wars and the Cold War. The museum is composed of a set of large adjoining hangars, and an open-air part. The hangars are rich in dioramas, built around real weapons (both heavy and light), tanks, as well as rigs, uniforms and dresses from the corresponding ages.

The first hangar is centered on WWII. Here a large central diorama represents a scene from the advance of US forces on German territory. A group of civilians reacts welcoming the American forces with white flags, whereas some armed civilian guards and some German soldiers keep a more cautious attitude.

Among the original US vehicles is a light tank, starring in the movie ‘The Monuments Men’ besides actor George Clooney. A German Goliath self-propelled drone-tank is on display in this scene.

Two house facades imitating traditional German architecture complete this central diorama.

In the same hall, more dioramas show for instance a German anti-aircraft battery, with a four-barrel gun and a searchlight. Range-finding rigs are also on display.

To the far end of the same hall, a Soviet T-34 and a Sherman can be found, besides self-propelled cannons and more vehicles set in smaller scenes.

In a lateral passage, scenes from the African theater of WWII are displayed. These include vehicles and weapons with a distinctive desert camo coat. Another diorama displays a school in Germany from the same period, with young men involved in light anti-aircraft defense.

Scenes from pre-WWII and from WWI are presented in yet another, smaller hall. Field artillery pieces from WWI are clearly discernible from more modern ones. A field kitchenette from the time is also on display.

Classical display cases feature many interesting items, including military uniforms from WWI and WWII, military decorations, air navigation charts and flight instruments.

The Cold War is covered in the last two hangars. Here field guns, mortars and armored vehicles mainly from the Federal Republic and from the German Democratic Republic – some of them still working – are put on display, side by side.

The exhibition in this part is complimented by numerous flags and smaller pieces of military material, including communication gear, water mines, transport vehicles, a military Trabant.

Part of the show is an ex-DDR early MiG-21. This can be climbed (not boarded), providing a nice view of the ensemble.

The museum is close to Schweinfurt, geographically next to the border with the former GDR. A reconstruction of the Inner Border impenetrable fence (see this post), with original signs and plaques, is duly on display.

The outside part of the museum displays a few heavy armored vehicles from WWI, WWII and the Cold War. They include a rusty, US-made M26 Pershing tank from WWII, a Federal Germany Gepard anti-aircraft self-propelled battery from the Cold War, and more.

Visible from a distance are a set of US-made surface-to-air missiles, distinctive silhouettes from the Cold War age. These include a Nike Hercules surface to air missile. Surface-to-surface platforms include a venerable and pretty rare Matador early cruise missile. This grandparent of modern cruise missiles features a distinctive swept-back wing, and a booster underneath the fuselage to the back.

The nose cone of a Pershing (possibly) is on display, together with a rare Lance missile, a surface-to-surface missile from the 1960s-70s, in the inventory of the Federal Republic in those years. The plaque on the launcher witnesses the Canadian origin of the single-missile wheeled rack, built by Orenda.

Behind the missiles, aircraft on display are a Soviet designed Antonov An-2 biplane, and a US designed Republic F-84 Thunderstreak, in the colors of the Luftwaffe of Federal Germany.

All in all, this wonderful collection has much to offer for everybody with an interest in the military history of Germany since WWI to the Cold War era. The museum sets up reunions of enthusiasts, and special days with tank movements and live displays.

Getting there and moving around

The Stammheim am Main museum is located 7 miles south of Schweinfurt, a major center in the area, and about 12 miles northeast of beautiful Würzburg. It can be conveniently reached when traveling between the two, right on the bank of the Main river. The exact location is along the intercity road SW1, on the crossing with Maintalstrasse in the village of Kolitzheim. Parking right ahead of the entrance. Small restaurant on site. Since the museum is stuffed with tons of interesting items, even though compact in size, visiting may easily take more than 2 hours for an interested subject.

Former US Airbase, Giebelstadt

The now sleepy general aviation airfield in Giebelstadt has been a rather active military airbase for many decades. A Luftwaffe fighter base in WWII, it was among the first airbases to host the new Messerschmitt Me-262 jet fighter. In 1945 it fell in the hands of American forces, who intermittently used it for various temporary deployments and flight operations over the immediate post-WWII years. The early Cold War era and the 1950s were a new period of intensive use. The runway was lengthened, and more modern facilities for stationing troops and aircraft were built anew, in place of older and damaged German ones from the Nazi era. Powerful, cutting-edge radar installations were put in place, due to the proximity with the East German border. With the transition to fast jets, the proximity of the airfield to the border was actually too much, so that interceptors could not scramble in time from Giebelstadt, in case of an enemy attack from beyond the Iron Curtain. However, this would be an advantage for reconnaissance missions, launched during the Eisenhower administration, starting in 1956.

Giebelstadt was one of the few bases for the balloons of Project Genetrix. That was a first, partly successful attempt to gather intelligence through unmanned overflights of the USSR. In the same years, Giebelstadt was intended as the main operative base for the CIA Lockheed U-2s, to be used for a more risky – since manned – but much more effective way to collect photo and signal intelligence.

The actual deployment started in 1956, with some delay due to the need to prepare the airfield for operation of the one-of-a-kind Lockheed U-2. The latter flew in the meanwhile from Wiesbaden, where the headquarter of US military in Germany was at that time. This was not much liked by the US intelligence community, since the latter city was more crowded than the small country village of Giebelstadt, and this exposed highly secretive U-2 operations to a higher risk of espionage.

Missions carried out by the U-2 were of basically two types. The first was relatively risky ELINT missions along the border with the USSR, where defenses were stimulated without entering the enemy airspace, to obtain precious information on the reaction capability and the enemy anti-aircraft barrier, including the position of radar sites, etc. The second mission type was high-risk ELINT/PHOTINT missions, or ‘overflights’, where Soviet airspace was actually penetrated. In the latter case, the U-2 made use of its superior altitude and range performance to carry out long missions above the defenses of the USSR. As known, the development of high-performing SAMs, reaching up to the cruising altitude of the U-2 meant it was not invulnerable any more after 1960. This put an end to overflights. However, a total of 24 mostly successful overflight missions were carried out between 1956 and 1960, each of them specifically studied and approved with the direct involvement of president Eisenhower.

Besides missions along the border, or over satellite countries of the Eastern Bloc (still considered a high risk, but not as high as a direct overflight of the USSR), a single overflight of the USSR was actually flown from Giebelstadt. This was mission No. 2040, flown on October 13th, 1957, with Hervey S. Stockman at the controls. A report from this mission can be found on a CIA document here.

Following the end of the U-2-based intelligence missions, Giebelstadt was ceded to the US Army in the years of Kennedy. The Army used it as a huge base for helicopter operations well into the third millennium – the base was deactivated and returned to Federal Germany only in 2006.

Today, the now private airport can be barely neared without triggering security service. However, even a quick look along the fence will reveal clear traces of the US military tenancy. From hangars to fences, to softer constructions north of the airfield, everything is much US military standard.
