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

The БАРС system – The tropospheric network of the Warsaw Pact

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

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

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

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

The Wollenberg site – Bunker 301 ‘Tushurka’

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

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

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

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

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

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

Sights

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Getting there & Visiting

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

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

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

Preserved Cold War Bunkers in Northern England

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

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

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

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

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

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

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

Hack Green Secret Nuclear Bunker

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

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

History

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

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

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

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

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

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

A tour of the bunker

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

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

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

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

Ground floor

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Underground floor

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Getting there and visiting

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

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

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

York Cold War Bunker

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Getting there and visiting

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

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

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

The armed forces of the German Democratic Republic (GDR), named NVA (‘Nationalen Volksarmee’, or National People’s Army), and the Western Group of Forces of the USSR coexisted on the territory of the communist-led GDR for the entire duration of the Cold War. They were basically independent from one another at least in terms of organization. The NVA was sized according to the interests of a highly militarized, but relatively small country in the core of Europe, and its vocation was mainly tactical. Nonetheless, the NVA boasted several branches, and in particular a land army, an air force and a navy.

Actually, the attack plan of the USSR in Europe – constantly updated over the years – foresaw a total, ‘one-shot’ massive attack aimed at reaching the North Sea coast in the shortest time possible, starting from the border with the West, thus primarily from the GDR, and making use of tactical nuclear weapons on key-targets in Western Europe. An involvement of all Armed Forces of the Warsaw Pact – beside the Soviet Red Army – was part of the plan, and as a result especially the good level of the military supply of the GDR was always a concern in the eyes of war planners in the Eastern Bloc.

When thinking of missiles and the Cold War, images of the parades on the Red Square in Moscow typically come to one’s mind. However, local national Armies of nations in the Warsaw Pact indeed had armed forces on their own, and usually also missile brigades incorporated in them.

This is the case of the NVA, which was fed by the USSR with the most advanced rocket technology, as soon as missiles grew in size and reliability to become significant warfare items. An excellence of Soviet rocket warfare has been the great care for the advanced deployment and ease of transportation of any assets, partly dictated by the infrastructural difficulties of a country so huge and so extreme in terms of terrain conditions and seasonal changes as the USSR. Actually, Soviet transport vehicles for missiles since the early 1960s matched missiles of virtually any sizes, of course including those for theater operations, which are intermediately compact and lightweight, especially when compared to larger, heavier and longer-range strategic missiles.

The arsenal of the NVA in terms of missiles was kept up to date between the early 1960s – as said, the beginning of serious rocket-based warfare and correspondingly war action plans, also in the West – and the end of the Cold War. Following bilateral Soviet-US disarmament treaties in the late 1980s, a transition period was started, obviously influenced by the 1989 anti-communist revolution and the starting of the German reunification process. The NVA was dissolved and its assets incorporated in the armed forces of Federal Germany in 1990. Due to the changed global relationships following the collapse of the USSR, most rocket forces in Europe, originally intended to fight a war on the continent, were significantly reduced or totally disbanded.

In its heyday, the missile forces of the NVA totaled two regular Brigades, incorporated in the land forces of the NVA, and eleven independent Brigades. They were supplied over the years with SCUD-A/B, Luna and Oka missile and corresponding transport/launch vehicles in various versions. The warheads supplied to the NVA were usually conventional. However provision was made for nuclear warheads, which were always kept under the direct control of the Soviets in two purpose-built nuclear depots (see this post).

An excerpt of the rich history of the rocket forces of the NVA can be reviewed visiting the nice exhibition of the ‘Militärhistorischer Verein Demen’, which translates into ‘Society of Military History of Demen’, located in the homonym village in Mecklenburg-Vorpommern, the northernmost district of the former GDR. It is easily reachable less than one hour driving inland from Lübeck or Rostock on the Baltic Coast. The display of this society of enthusiasts reaches even further, documenting the presence of missile forces of the US and within the Bundeswehr of Federal Germany, supplied with American material during the Cold War.

This post covers this very nice and lively collection, really special both in terms of items on display, and for the fact that most vehicles there are still in working order – when visiting, you will have good chances to see them moving around!

Photographs were taken in 2021.

Sights

The base in Demen became active between 1975 and 1977, when the 5th Mobile Rocket Technical Base (BRTB-5) and later the 5th Rocket Brigade (5. RBr) of the NVA moved in with all their assets. The 5. RBr had been originally formed in 1962 with another name (Autonomous Artillery Brigade sABr-2), and supplied with SCUD-A missiles. In 1964 it converted to SCUD-B theater missiles. It was re-founded as the 5. RBr only in 1967.

In 1985 it was resupplied with the SS-23 Spider (aka Oka, or 9M714 in Soviet coding). The INF treaty signed in 1987 by President Reagan and Secretary Gorbachev targeted that type of missile, which was therefore short-lived, and disposed of as soon as 1990 in the NVA (later Bundeswehr).

The exhibition in Demen offers an insight in the missile types in use by the NVA. They have been placed inside a building of the former NVA military base on site, which following disbandment of the NVA has been converted into a multi-functional facility, with local companies and diverse businesses taking over the hangars, warehouses and residential buildings.

A complete 9P113 Soviet-made launcher for the old Luna (NATO: Frog) missile is on display, with the missile on top of it.

Right besides is a cutaway exemplar of the highly-successful Soviet BTR-60 armored personnel transport vehicle. The twin-engined propulsion system is clearly visible.

The collection in Demen is unique in having some fully working vehicles on display.

The bulkiest and most impressive is surely the movable launcher 9P71 for the Oka missile. This eight-wheeled truck can be seen in the pictures sheltered in a hangar, or moving around the premises of the former NVA base!

In this video you can see the vehicle displaying the movable crane – still perfectly operative – for maneuvering the missile.

In this other video you can see the launcher carefully coming back into the hangar, following a live display.

Another vehicle from the Eastern Bloc and still in fully working condition is this technical van UAZ-452. Not only it can move on its wheels and engine, but it looks still perfectly equipped!

The collection in Demen is not exclusively devoted to the Eastern Bloc or the GDR either. Instead, you can find both static and ‘live’ items on display from the NATO side of the Iron Curtain. The latter include a M752 amphibious vehicle for transporting the Lance missile.

This vehicle with tracks was highly popular in the US and many NATO countries, including Federal Germany, the Netherlands and Belgium. Another unusual living exemplar is that of a Swedish Hägglunds Bandvagn BV-206, aka SUSV in the US Army. A very versatile tracked vehicle with a trailer made for the snowy terrains of Scandinavia and the Polar continents as well, today running around the former NVA base in Demen!

Three warheads from US missiles deployed on the territory of the FRG are on static display, allowing for a nice size and shape comparison. They are a Pershing, Honest John and Sergeant warheads, all theater missiles from different stages of the Cold War. On the outside, a fully assembled Honest John is similarly on display.

The Soviet-made missiles on display are a Luna, an Oka and a SCUD. The Luna, painted in gray, is partly cut to show the inside mechanisms and arrangement. Also the corresponding warhead has been cut to show the inside structure.

The pretty rare Oka missile has not been cut – a true icon from the Cold War in the mid-1980s!

The SCUD has been separated from its warhead, and partly cut and cleverly lighted to show the inside plants and arrangement.

Besides the SCUD also some original parts of the guidance system have been put on display, together with some technical testing/monitoring material of Soviet or East-German make – note the writing in Cyrillic.

Display cases all around host original technical material, many fantastic models mainly from the arsenal of the NVA and Red Army during the Cold War, as well as exceptionally detailed and informative panels concerning the history of the missile forces of the NVA (as well as specifically on some of the missile systems on display).

Many evocative photographs and videos from the days of operation complete the display in the hangar.

Some very rare artifacts are from the early stage of rocketry, and include components of von Braun’s first works – most notably the V2 – from the Third Reich era.

A second branch of the exhibition, physically hosted in another building of the complex, is composed of the two rooms packed with memorabilia items mainly from the history of the 5. RBr

These include books, photographs, and beautiful memorial crests, especially from joint exercises carried out with the Red Army with live firing of the missiles in a dedicated polygon in Kapustin Yar. People taking part to these exercises – held back in the 1980s – are now volunteering in the Society, and you may be so lucky to meet them for a nice talk and for getting a more lively insight on the history of the NVA rocket Brigades. Staff from the 5. RBr deployed to the polygon by land, and the original map retracing their movements across the USSR is on display.

Also on display are original technical boards displaying some operating concepts for the Oka missile – in Russian, a one-of-a-kind relic of the Cold War years!

Getting there & Visiting

The small village of Demen is located in the northeastern quarter of Germany, about 25 miles from the Baltic shoreline, 45 miles from Rostock and 55 miles from Lübeck, both port towns on the Baltic sea. You can reach the display by car here. Access to the former NVA complex, now called Evita complex, is via the road L091, to the west of Demen.

One of the many hangars in the Evita complex hosts the collection, and the memorabilia rooms are in an adjoining building. Opening times are very limited (basically in the weekends), but this is due to the fact that they coincide with volunteers’ gatherings. On the plus side, you are likely to see at some vehicles running.

For interested subjects a time of 1 hour may be the minimum for a visit to the static display, if no vehicles are moving around. If there are live displays, or volunteers to interview, you may spend there 2 hours or more.

German is obviously the main language spoken (and often times the only option in this part of Germany), but English is nonetheless understood and spoken by some of the volunteers. Website here.

Soviet ‘Monolith’ Nuclear Bunkers in Poland – Survivors & Ghosts

Since the beginning caught in the storm of WWII, Poland saw its border changed again in 1945 by the Western Allies and the USSR – the lack of natural borders meant that fate for this Country several times over the centuries. Furthermore, as a massive flow of Soviet forces had been pivotal in repelling Hitler’s forces, similar to other nations sharing a border with the USSR, Poland found itself deep in the sphere of influence of Stalin’s Soviet Union. A communist dictatorship was installed starting 1945, due to last until the end of communism in Europe in 1989.

As a matter of fact, Poland turned out to be by far the most populated and largest of Eastern Bloc countries. Strategically placed in the middle between the USSR and free Western Europe, with a wide section of the Baltic shoreline and a huge, mostly flat territory, similar to the German Democratic Republic nearby, Poland was the theater of a significant militarization effort by the Soviets. Not only the Polish army received Soviet war material in large stocks over the full span of the Cold War, but the Red Army also actually had significant assets scattered over Polish territory – its huge Northern Group of Forces being stationed there, with tanks, aircraft, dedicated bases, firing ranges, as well as several tens of thousand troops and their families, making for a kind of military colony of the USSR.

What is possibly less known is that also Soviet nuclear weapons were stationed in some satellites of the USSR, like the GDR (see this and this chapters, for instance), Hungary (see this chapter), and of course Poland.

Some elements of the global picture have been introduced in another chapter, dealing among other things with a Basalt-type bunker built for storing air-launched nuclear systems, on the premises of the Soviet airbase of Wiechlice (Szprotawa). Yet as can be argued from the general map of of nuclear depots known to Western intelligence, dating from 1979 (‘Warsaw Pact Forces Opposite NATO’, Vol.I-II, CREST record number 0005517771, declassified and released in 2010, here), there were also three major depots of the Monolith-type in Poland. Similar to Stolzenhain and Lychen in the former GDR (see this post), these depots were larger, multi-chamber storage facilities, intended to store primarily missile warheads for longer periods, for instance to complement the SCUD launch system for theater missiles.

The uniqueness of Poland in the panorama of Cold War archaeology lies in a generally positive attitude towards preserving some traces of this dramatic piece of recent history, when the map of Europe was markedly different from now, and the western world found itself multiple times on the verge of a nuclear confrontation, to be fought on the very territory of now wealthy Core Europe. As a result, an impressive number of war museums putting on display military stuff from all the 20th century can be found scattered over the broad territory of today’s Poland.

Even more important, a certain number of former Soviet military installations are being either actively preserved, or at least not condemned through demolition works or re-assignment to improbable new uses. This is despite a totally justified negative attitude towards the Soviet occupation forces and communist dictatorship. This attitude marks an unusual difference between the cultural attitude of the fierce Polish people towards recent military history and Soviet occupation, with respect for instance to Germany or Hungary, where the comprehensible dislike for the Soviets has taken a shape in leaving behind – i.e. more or less demolishing – every trace of a Soviet military presence, and especially in the former, reducing military museums to a minimum.

Among the most prominent Cold War relics you can find in Poland are the three Monolith-type nuclear warhead bunkers mentioned above. One of them – the Podborsko site – has been restored with 90% original material, and makes for a world-class, top-tier museum in the panorama of Cold War military history. The other two, Brzeznica-Kolonia and Templewo, have been left to nature and have now become ‘Soviet ghosts’, but they are advertised with panels, providing some info, and while access is not encouraged, a quick look inside the bunkers, as well as freely walking in the former premises of these bases, is of course possible.

This post covers these three Monolith-type sites, with a focus on the unique preserved Podborsko site, which needs to be on the shortlist of everyone with an interest in Cold War technology, as well as in the history of the nuclear stockpile. All sites were visited, and all photographs taken, on a trip to western Poland in summer 2020.

Sights

All three sites are in northwestern Poland. GPS coordinates are provided in the respective sections. Despite being not too much afar from each other, due the relatively slow connection roads in the area, visiting all three places in one day is not possible. Furthermore, the area is quite dense in both general interest and Cold War related destinations, so I would advise planning a trip to this region of Poland and listing these sites among other destinations.

Podborsko Site – Objekt 3001

A good specimen of a Monolith site, Podborsko – or Objekt 3001, as per the official military listing of the Cold War years – was centered on two large half-interred bunker, each with two big side-wards opening tight doors at ground level, providing access to the interior with the trolleys used to move the nuclear warheads from the transport trucks to the cellars.

For an increased protection in case of an attack to the site – likely listed among targets of strategic value by Western Countries – a second tight door was put immediately next to the external one, creating a tight, blast resisting and insulated airlock between the interior of the bunker and the outside world.

Both doors to the two ends of the airlock can be – and are – opened via a manual crank system. Two men are needed to actually move the doors however – they are really heavy! A servo-assisted system was in place originally.

An interesting detail is the original sensor for the door status, part of a security system of the base.

Similar to their US counterparts, the Soviets took the problem of security of the nuclear arsenal pretty seriously. Each door on the path followed by the warhead from the outside to the cellar, including the airlock doors as well as the cellar doors inside the bunker, were associated to a trigger. When the corresponding door was opened, the trigger sent a signal via a dedicated cable link to the headquarters of a dedicated branch of the Red Army offices in Moscow, Russia, which was kept constantly updated on the status of each critical door in the depot. The link was via purpose-designed vacuum-protected cables – the actual wiring ran along a vacuum manifold, so that in case of the cable was bitten and the vacuum manifold collapsed, an emergency signal was immediately sent to the nearest nodes of the network, allowing surveillance staff to intervene promptly.

The opening of and closing procedure of the airlock doors involved communication with a post in Moscow too, which started with the local guards communicating their intention to open the doors via a system housed in a blue cabinet besides the tight door. As the signal traveled from the bunker to the headquarters and back, the opening of an airlock was not a quick operation! Original writings in pencil can still be found in the cabinet.

Past the airlock, you land on an elevated concrete platform. From here the warheads were moved to the underground floor via a mechanical crane. This is still standing today, with limit indications in Russian.

From the platform you get an excellent lookout of the bunker structure. You can see a twin suspended platform to the opposite end of the underground floor, with a tight door shut closed. Along the long sides of the main hall, on the underground level you see several doors. On the right hand side, big sliding doors painted in white give access to the cellars, where the warheads spent most of their time in rest. On the opposite side are smaller man-sized doors, giving access to the technical area, with provision for the men of the permanent bunker watch.

The stairs leading downstairs are among the few complements to the original structure – they have been put in place to ease visiting. Originally, the underground floor could be reached from the suspended platform only via a lateral manhole with a vertical metal latter.

The warheads are long gone today – the site was built in the late 1960s, and was emptied of its strategically relevant content in the late 1980s, to be finally ceded back to the Polish government after the withdrawal of all Russian forces from Europe. The cellars today are mainly empty, and used to showcase interesting items related to the site.

First, you can see a scale model of the entire site. In Soviet times, the place was a full scale military base. It included a separated area with living facilities for the troops and their families, who ran the base with both technical and surveillance tasks. Today, this area has been taken over by the government, and used as a prison – Podborsko is rather secluded and far from populated areas on the Baltic coast. Furthermore, as said there used to be two twin bunkers. Today only one has been restored, whereas the other is sealed and waiting for reuse. Between the sectors of the base multiple fences with barbed wire, concrete walls, foxholes and other deterring/defense devices and systems were in place, making the innermost part of the base with the bunkers rather inaccessible.

An original armored cabinet from the time of operation is still in the corner of a cellar, its original use is uncertain.

In another cellar you can find everyday items and relics from Soviet presence in the area. These range from toothpaste to children’s toys. Also more military-related items, like cartridge boxes and even original Soviet military dog tags have been found scattered over the area!

You can also find weapons, a scheme of the base in Russian, anti-radiation suits, and parts of the body, control and guidance systems of a Soviet SCUD theater missile – the corresponding warheads being the main business in Podborsko. There is also a copy of the plan of an attack scenario for Western Europe, showing some targets on the respective sides of the Iron Curtain.

One of the cellars has been left empty, with a mock-up of a warhead, resting on one of the original trolleys. This is particularly evoking, despite being just one out of the high number of warheads usually stored in a cellar. The actual number of warheads residing in each Soviet storage over the years is still today not totally clear. However, reportedly former Soviet staff support there was in a single Monolith bunker in Poland enough nuclear material for the whole attack plan over Europe, meaning a number of several tens warheads per site.

The trolley is original as said, and it shows the function of the slots on the ground of each cellar, which allowed anchoring the trolley firmly in position. This was possibly needed also in the extreme case of a blast hitting the bunker, so as to avoid any unwanted displacement of the trolleys.

A fourth cellar displays a set of panels, outlining the history of the Cold War.

As said, the security triggers telling the status of the door can be found close also to each of the sliding doors of the cellars.

Before moving to the technical area on the other side of the bunker, a look to the central hall reveals a number of original material. In particular, you can find an interesting set of instruments, handles and gauges packed together in a metal cabinet. Their function was that of monitoring the state of each warhead. Nuclear material needs to be stored in precise conservation conditions, so warheads were kept in dedicated cases. These were inspected regularly by connecting them to the monitoring system and recording the corresponding gauge readings. Traces of the positioning markers for an inspected trolley can be found close to the cabinet, painted on the ground.

Another conspicuous sight in the main hall is the heating system, needed to keep the inside atmosphere at a constant assigned temperature and humidity level, to guarantee the health of nuclear material. A big array of heat exchangers takes the top part of a side wall in the main hall.

The technical part is made of two main parts, and is accessible on the long side of the hall opposite to the cellars. One part is made of a blind sequence of three narrow compartments. Here you can find a case for manipulating dangerous chemicals, with protection gloves once protruding inside. Nearby, a sink and some cabinets recall a medical room.

This area was designed to manipulate and check the triggers of nuclear weapons in use at the time of construction of the Monolith bunkers (late 1960s). These made use of reactive materials, thus requiring some precautions and a complex maintenance procedure. They were phased out soon after the construction of the site though, so this part of the bunker was basically unused since that time. A tight door connects this area to the main hall.

The second part of the technical area is arranged along a U-shaped corridor, starting and ending in the main hall. Similar to the previous technical part, a small sealed door connects the corridor to the main hall.

The first technical rooms you meet are related to climate control.

Next you find a big water tank. Close by there is a single toilet. This was reportedly seldom used, as drainage did not work properly due to the underground placement. Watchmen during their shifts in the bunker went out for their physiological needs.

Going in and out for pedestrians was made possible through a man-sized airlock. This is perfectly preserved in Podborsko, similar to the passage leading up, by means of very steep metal ladders.

Another interesting sight in the technical area is the air filtering room, which is close to the small living area for the watch staff. In case of an attack to the facility, making the area poisonous possibly also due to fallout, this huge filtering system allowed the troops inside to survive for some time.

The electric control room is in almost mint condition. Only the major connections to the external power lines – not there any more – have been cut. Same electric connections still bear their original hand written identifiers!

An original – and rare – handbook with some illustration of standard trolleys is among the artifacts to be found in this incredible exhibition.

Concluding the technical part, a massive Diesel power generator, with its ancillary air pumping and exhaust expulsion systems, is still there in a rather good state.

Back outside, the Podborsko site features also a Granit-type bunker, perfectly preserved with its metal doors – seldom found elsewhere. Granit bunkers were much softer in construction than the Monolith-type, and they might be used for storing assembled missiles, command posts and more. The one in Podborsko is another Soviet mystery – it is hard to tell to what purpose it was built, probably in the late 1970s-early 1980s.

The second bunker, very similar inside to the main one, is sealed and waiting for restoration. You can walk the exterior, where some remains of the truck loading/unloading platforms can be found. Traces of a fence line can be seen to the back.

Getting there and moving around

The Podborsko site is a branch of the ‘Muzeum Oreza Polskiego w Kolobrzegu’, called ‘Cold War Museum Podborsko 3001’ (‘Muzeum Zimnej Wojny Podborsko 3001’ in Polish). The town of Kolobrzeg is on the Baltic coast, roughly a one hour drive from this bunker, and hosts other branches of this nice museum (a tank and artillery collection, a marine branch,…). The dedicated website of Podborsko is here, to be Google-translated from Polish. The Podborsko site is open on a regular basis at least in summer, and also by appointment. I guess the visit may take about 1 hour once on site.

My visit was a special one though, as I had the chance to join in for a special thorough visit of the site, prepared for Dr. Reiner Helling, a nuclear scientist from Germany, and one of the most knowledgeable historians in the field of Soviet military presence and nuclear assets in Europe. Dr. Helling extended the invitation to me, so I had the unique chance to take a private, tour with the local curators of the branch, Mr. Mieczysław Żuk and Mr. Pawel Urbaniak. We spent some hours touring the site inside and out – special thanks to all three for an unforgettable experience!

Getting to the bunker is easy by car. Driving will be along an original Soviet service road, which can be faced with a regular city car. You may park once on the spot once there.

Brzeznica Kolonia – Objekt 3002

The site in Brzeznica Kolonia can be found close to the former Soviet village of Klomino – pretty famous in its heyday among the urbex community – and in the vicinity of the airport of Nadarzyce, still active today.

The site has been largely wiped out, but the bunkers and a little more hardware survive, in a ghost condition. However, the site is advertised with some explanatory panels, and it is also quite popular among the locals, which come here to take a couple of pics in a weird scenery.

One of the most portrayed items on the premises of this site is the Granit bunker, which is today lacking its original metal door. Similar to Podborsko, this ‘soft’ bunker was added at a later stage, and its function is to be guessed. Interestingly, some painted stripes can be found on the pavement, possibly marking the position of some trailer or gear.

Similar to Podborsko, the two major Monolith bunkers are arranged with their respective axes crossed. The eastern one can be accessed from its southern door pretty easily. Inside, it reveals its similarity with Podborsko, except for having being spoiled of any metal part – from the doors to the heat exchangers – and having hosted a wildfire or similar, as can be guessed from the sooth on the walls and ceiling.

Getting to the underground level from the suspended platform is not safe if you are going alone, like me, as the original metal ladders have been taken away. However, hard spoiling has to be expected also in the technical rooms.

Walking on top of the bunker, you find traces of the man-sized side entrance, completely interred.

Ahead of the bunker and to the back, traces of the loading/unloading platforms for trucks can be still recognized.

The westernmost bunker is easy to access from the eastern gate. Inside, it has been spoiled of any metal, similar to its twin brother. It is in a generally better shape though, without sooth on the inside walls.

In both bunkers, traces of original painting can be found.

In between the two bunkers, a number of smaller buildings are still to be found, including – apparently – a water tank, and some sentry boxes.

Also, more than in Podborsko you can appreciate a network of foxholes, which despite fading in nature, can be clearly noticed departing from the main roads once crossing this military installation.

Back to Nadarzyce nearby, you can get access to the former ghost town of Klomino. The majority of the original Soviet blocks have been wiped out, but most incredibly some of them have been restored and are today inhabited. This, and the very bad access road, make this place worth a visit only for completing the tour of this once big Soviet installation, without adding much. There is really not much left to see in Klomino.

Getting there and moving around

As said, the bunkers are pretty popular among the locals, who go there by mountain bike or car. The site can be accessed via an unpaved service road, totally safe also for a standard car, taking south from Nadarzyce. The parking point is here 53°25’51.0″N 16°34’43.6″E. There are also some picnic tables, an explanatory panel and some warning signs.

Templewo – Objekt 3003

Similar to Brzeznica Kolonia, the Templewo site has been largely reclaimed, and is now partly preserved as an unusual spot in the wilderness. The base has completely gone, but the the monolith bunkers are still there.

They can be found following an original Soviet paved road.

Both Monolith-type bunkers can be accessed with little difficulty, despite the gates having being mostly interred, like for Objekt 3002.

With respect to the latter, they appear in a generally better shape, albeit stripped of any metal hardware. Again, going down to the underground level is not recommendable if you are exploring alone, as there are no ladders from the suspended platform.

Taking a detour from the Monolith bunker area reveals an extensive network of trenches and foxholes, with abundant traces of – dangerous – barbed wire.

Finally, a single Granit-type bunker, added to the site at some point similarly to Podborsko and Brzeznica Kolonia, has been completely taken away. Only the side embankments can be seen today, wet and with a slimy puddle in between.

Getting there and moving around

The site can be reached by car, shortly north of the road connecting Trzemeszno Lubuskie to Wielowies. A parking area, part of the former base, is here 52°25’16.2″N 15°19’10.6″E. No special car needed, you can drive the original Soviet service road with a standard city car. From the parking, you may move north for a very short walk. You will soon find mild warning signs concerning the bunkers.

The area is located next to a huge military proving ground, so loud bangs might be heard quite easily, and you will see signs telling not to go south with respect to the access road to the former nuclear installation. However, the bunkers themselves are out of the danger area, and totally open and accessible.

The Red Army in Hungary – Airbases, Bunkers and Ghost Towns

Similar to other satellite countries like Poland, Czechoslovakia and the former German Democratic Republic, for decades after WWII Hungary was under the strong influence and de facto military control of the Soviet Union. As a result of the anti-communist revolution of 1956, when the Soviet nearly lost control of the country for a while, a massive Soviet force was stationed in Hungary to prevent further turmoil – the so-called Southern Group of Forces – acting in parallel with the local Hungarian Army, although in a coordinated fashion.

This was reflected by the turning of several existing airfields and training grounds from older times into modern Soviet bases. Their premises, and the territories around them, were completely severed from the rest of the Country, leaving the Soviet forces with a great freedom of action concerning the deployment of unspecified numbers of troops, tanks, aircraft, communication gear, and even nuclear warheads. Furthermore, the families of the Soviet troops stationed in the Country were hosted in dedicated purpose built – or purpose converted, pre-existing – villages.

All this left traces of course, and after the end of communism in Europe, and later the collapse of the USSR, the majority of these installations were either abandoned or converted to some other use. Abandoned – i.e. not converted – Soviet bases and installations in Hungary were pretty many. Today, many of them are being demolished, or are still standing, but severely damaged after years of disrepair. Actually, the best preserved installations are those waiting for conversion or for some yet-to-be-defined destiny, and currently under custody of private owners or the state.

This post is about some of these installations, and it focuses especially – but not exclusively – on storage bunkers for nuclear warheads. Besides being especially appealing to mystery-hunters and urbex explorers, such places are an interesting testimony of the serious attitude of the Soviets towards a war in the European theater. This was considered a likely event in many instances over the decades of the Cold War, from the 1950s to the years of President Reagan’s Strategic Defense Initiative. The money spent over the years by the Soviet Union to build up a dedicated military infrastructure, and the deployment of tactical warheads close to the designated targets in western Europe to prepare for such scenario, show that the USSR did not think of fighting a nuclear-based final battle just as a mere theoretical exercise.

Photographs were taken in August 2020.

Sights

Based on a CIA report dating from 1979 (‘Warsaw Pact Forces Opposite NATO’, Vol.I-II, CREST record number 0005517771, declassified and released in 2010, check it out here), there used to be a small yet significant number of bunkers for the storage of the Soviet nuclear stockpile in Hungary. The following map, taken from this report, shows their approximate location and type.

Despite a clear correspondence of each symbol with a Soviet bunker construction type is not readily available, it is possible to reconstruct the information as follows.

The only solid triangle corresponds to a Monolith-type storage bunker, the largest and most sophisticated type of storage in the Soviet standard inventory, made for long-term storage of nuclear warheads. This site is located close to the village of Urkut, in the middle of an extended region, once the largest part of Hungary managed exclusively by the Soviet military. In this area you can find also the headquarters of the Soviet forces in Hungary, the Southern Group of Forces, located in the small village of Hajmasker, as well as the airbase of Veszprem, with an annexed village with housing for military staff and their families.

Monolith-type bunkers were seldom built on the premises of airbases or other military bases. They were prepared mostly in secluded area, shrouded in the vegetation, so as to avoid any unwanted attention as much as possible. They would store high-yield warheads for theater missiles (e.g. SCUD missiles). Urkut is no exception, as there are no airfields close to it. It is shrouded in the vegetation, and far from any village of significant size.

Back to the map, round dots represent Basalt-type storage bunkers, which are most commonly to be found close to airfields. This type of bunker is significantly large, and capable to store air-dropped/launched tactical weapons with nuclear warheads. Two sites are shown on the map, of which only the one on the premises of the former airbase of Kunmadaras could be located.

Finally, the squares correspond to Granit-type storage bunkers. These were of much lighter construction with respect to Monolith and Bazalt, and their purpose could be that of hiding either missile launchers of various size, or command/communication posts. Much has to be guessed about the actual function they had in all places where they were built. In Hungary, three such bunkers are reported on the map, of which the easternmost is on the still active airport of Debrecen, the westernmost is on the small local airport of Heviz (formerly Sarmellek), and the latter is presumably on Tokol, a major airbase in the outskirts of Budapest, Hungary capital city.

In the following you can find some pictures from the storage sites of Urkut, Kunmadaras and Sarmellek, plus pictures from the Soviet bases of Veszprem, Tokol and Kalocsa, and from the former Soviet headquarters in Hajmasker.

Urkut Monolith-Type Nuclear Storage Site

The Urkut site is also familiarly known as ‘little Moscow’, due to the fact that this site hosted also a very small, perfectly Soviet-style quarter for the troops working on the base, or being trained in the local training center. The site is in a wide and pleasant valley with a north-south alignment. There used to be two access roads which today take from the main (and only) road running along the mostly uninhabited valley, connecting Urkut (to the north) and Nagyvazsony (to the south). The two access roads take you to the main gates, placed to the north and south ends of the complex.

Similar to other nuclear sites based on the Monolith-type bunker model (see for instance this post for an accurate pictorial description of another one), security was clearly a major concern. Still today, walking in the trees and approaching the base without going the official access roads, you will meet four external fences.

The outer one is made of concrete posts and barbed wire, but today this is mostly gone – which makes it practically more dangerous, as the few remnants of suspended barbed wire are barely visible, and much leftovers are partly hidden by the abundant low-growing vegetation.

Next you will come to a concrete wall made of prefabricated slabs, with traces of barbed wire on top. This is still today basically impenetrable.

Once in, you will find two further lines of barbed wire, suspended on concrete posts. This double fence of barbed wire is still in very good shape, and creates a watch corridor.

Inside the perimeter, you can spot a network of trenches and foxholes.

In Urkut, the training grounds and bunkers are close to the northern gate, whereas to the south you can find the former living quarters for the troops. A prominent training hangar can be found in the northern part of the base.

Inside, a perfectly conserved mural with the heads of Marx, Engels and Lenin, and Moscow’s Kremlin in the background, is still hanging on top of the main gate.

Along the hangar, a corridor with classrooms clearly shows the intended function of the building.

Not far north from this major attraction, you soon meet a smaller technical building, and the southern Monolith bunker close by. Bases centered on the Monolith type typically had two independent twin bunkers built onsite, usually with their axes tilted by 90 degrees, so as to minimize the chance of a single bomb effectively striking both bunkers. This is not the case in Urkut though, as both bunkers are built along an East-West direction. Urkut is different from other Monolith sites also for having been built on the slope of a hill, so connection roads are never flat.

The warheads reached the bunker by truck. A covered loading/unloading platform can be found on both opposite entrances to the bunker. For the southern bunker, you can see in the pictures the platform is still in very good conditions, with colored signs on the pavement for facilitating movements. Even the lamps are still there!

The main access to the bunker was via an airlock, with two gigantic square-shaped blast-proof doors on each side. In this pictures you are seeing the western access to the southern bunker.

The innermost part of the Urkut bunkers is inaccessible, as the inner doors of the airlocks are shut. Yet it is possible to get access to the airlocks. For the southern bunker, going to the eastern access you find a covered platform similar to the western one, yet here the roof has partly collapsed.

You may open the outer door of the airlock, and get access. Here you can see writing in Russian. The state of conservation is generally speaking extremely good.

On one side of the eastern loading platform, you can see a standard Soviet military transportable trailer, maybe a local operation control center.

In order to get to the northern bunker you need to climb uphill, crossing some further inner fences – it was typical to Soviet bases having multiple fences inside military bases, separating parts with different functions and levels of security.

While loading platforms of the southern bunker are tilted by 90 degrees with respect to the axis of the bunker, for the northern bunker they are aligned along the same direction.

The eastern access to the northern bunker features is fairly well conserved. Also here, it is possible to access the airlock, but the inner gate is sealed.

On top of the northern bunker, you can find the ‘pedestrian access’ to the underground cellar. The gates used to carry the warheads in and out were usually kept closed, and the troops or technicians staying inside the bunker, which had provision for a few men overlooking the sensitive ordnance 24/7 in shifts, could enter and leave the bunker via a more modestly sized hatch. This could be reached from the top of the bunker, descending very steep stairs to the level of the bottom of the internal chamber. There you had an airlock, with tight doors the size of a man. These are closed in Urkut, but you can see the external tight door in its original yellow coating with conspicuous writing in Russian.

The soft construction protecting the access to the stairs is today severely damaged.

Finally, the western entrance to the northern bunker is very similar in shape to the eastern one. The northern gate of the complex is not far from here.

Also here, the airlock can be accessed, but the bunker cannot be entered.

All in all, the Urkut site is in an exceptionally good condition in the panorama of Soviet remains. A conversion into a museum would be highly desirable, and would require a very little effort. The fact that the bunkers are closed clearly suggests the inside was not touched, so maybe only basic renovation would be required to make the place a top-notch attraction for Cold War history enthusiasts.

Getting there & Moving around

The site is either on private land or state-owned. In any case, it is not officially accessible. The access roads are guarded, with people (and watchdogs) living on site. Car access on the access road is not allowed either. Walking on the site you may find several vibration sensors with cable connections likely to the booths close to the main access. For these reasons, further indications on access will not be provided.

Soviet Headquarters at Hajmasker Castle

Similar to Wünsdorf in Germany (see this post), Hajmasker Castle was built just before WWI, the focal point of a large military settlement of the Austro-Hungarian Empire. During WWII, it was used as a military command center, and as a local headquarter of the German Army in the latest stages of WWII, when the willingness of a part of the Hungarian establishment to put a quick end to the war by negotiating a peace treaty with the Western Allies caused the Germans to take direct control of that war theater.

After the defeat in WWII and the Soviet invasion, since 1945 the castle hosted the headquarters of the Soviet military in Hungary – just like Wünsdorf in the German Democratic Republic. Again in a totally similar fashion, the symbolic end of Soviet dominance in Hungary was marked by the last train for the Soviet staff leaving Hajmasker for the USSR in 1990.

As said, the castle is what remains of a larger military village. The building is really sizable, with a characteristic prominent tower on the front facade.

Walking around the castle you can find a theater hall opposite the tower.

The walls are pierced, so you can see inside, without getting access to the hall, which appears really one step away from collapse. To the back of the castle you can find traces of a large apron for military use, and direct access to the railway nearby.

Back to the tower, the original gate is not made for large vehicles, and the gracious artistic style of the construction clearly suggests a pre-Soviet design.

Climbing upstairs, you meet long corridors with traces of the offices of the top-ranking men from the Soviet military. Hajmasker is strategically located close to the region where the Urkut site is (see above), and where the former base of Veszprem is also located. The place is less than one hour from Budapest.

The view from the top floors of the building further reveals the size of the castle, together with the poor state of conservation.

Ahead of the entrance, a Soviet-style apartment block can be found, still inhabited today. Smaller buildings are all around the castle, both modern or from the age of the castle. You can find also the flat building of a former canteen, clearly Soviet-designed and today abandoned.

Getting there & Moving around

The place is located at the following GPS coordinates: 47.148319, 18.026145. The castle is formally off-limits, but it is totally abandoned and accessed by writers, creepy-ambience-lovers, as well as by the local population. You may park right ahead of the gate among the cars of those living in the local neighborhood. You will be spotted for sure when accessing, but nobody will likely interfere, as access is totally easy (no fences, no barbed wire,…), despite being formally prohibited. Enter at your own risk, as the building looks really rotting, with the roof partly collapsed, exposing wood and bricks as construction materials – considering their age, the high rise of the building and total disrepair over the last decades, this means high risk.

Veszprem Abandoned Airbase & Ghost Town

The old airfield in Veszprem acted as a major helicopter base during the Cold War, but style of the some of the older buildings betrays its 1930s origin as an airbase with annexed training academy. Of course, the Soviets enlarged its structure, and possibly as late as the 1980s they built massive housing in their typical poorly original style.

In the 1990s, with the change in the global strategic situation following the Soviet demise, the Hungarian government got rid of many military infrastructures, and Veszprem was on the list. Since then, the airport was turned into a short-lived base for commercial transport run by a private company, and as of 2020 it is at the center of a dispute, where the local municipalities are trying to get the land for other uses.

What you can see now reflects this state of things – trucks coming and going everywhere between the old buildings of the former airbase, with some demolition work being carried out and some gigantic commercial storage being built close by. The air-side of the airport appears basically dead, with no flights coming or going, not even small private aircraft operating around it. However, a control tower is still on site, so technically speaking the airport appears to be open for operations.

The place deserves a visit especially for getting a glimpse of the large structure of the maintenance hangars. From the outside, they can be spotted from a distance thanks to their tall curved rooftops.

The hangars have been divided internally in smaller spaces at some point. Getting access is possible in some of them, by the sight is rather desolating since the roof has mostly collapsed, and vegetation is taking over wildly inside.

Towards the airport you can spot more technical buildings, surrounding a wide apron. These technical buildings are apparently from a later era. The metal doors of the big curved hangars are such that getting larger helicopters in and out would not be possible. Maybe they were actually sized for the smaller aircraft of WWII, and their use was somewhat changed in a later time.

Between the hangars and the runway, you can find an impressive number of smaller maintenance buildings and garages, likely for trucks.

In some of them, a few signs in Russian can still be found.

Open air as well as indoor platforms for truck servicing are also there in a number.

Going even further towards the runway – and very close to it – you may find a light, partly wooden construction, with extensive remains of writings in Hungarian, including boards and stuff related to air operations. Here you see also some ‘modern’ writing in English. This is probably a kind o clubhouse of a local flying school from more recent years, likely the 1990s or later.

Looking at the satellite map of Veszprem airbase, you will notice a number of buildings put like spokes on a wheel. These were probably part of the original flight academy. These are today in a very bad shape, totally emptied and waiting for demolition. You can still appreciate the sober, yet stylish construction typical of the late 1930s, with some elements in common with Berlin Tempelhof (see this post).

‘Pravda’ paper was used for gluing the wallpaper in most Soviet bases, and Veszprem is no exception!

Farther away from the runway, you can easily spot massive buildings from Soviet times, like those you could find in Pripyat (see this post), and almost in every larger city of the former USSR.

Further buildings feature a rather peculiar style, with stone decoration you would not expect in military buildings. The fantasy of such decoration is not in support of a Soviet make, so these buildings might be from an older era too.

Getting there & Moving around

As said, this former airbase is technically an active airport, so the area of the runway is likely not safe to go. Yet the level of security is close to null, and you would likely be able to invade the air side before being stopped. However, no aircraft was spotted for the whole length of a multiple hour visit.

The older buildings, including the hangars, as well as the more modern housing from Soviet times, are in a really bad shape, and mostly dilapidated by looters and spoiled by writers. The more modern truck garages and the buildings closer to the runway are in a better shape.

Access by car from the south-western corner is not prohibited, so this may be a good way to get close to the buildings. Large parking opportunities, as the place is mostly unguarded and uninhabited. Just be sure not to interfere with local businesses. Even when spotting your car, the locals will not care about you (this was my case at least), so the place can be visited without much tension. However, for historians this place has not much left in store, and it may be visited mostly for the massive ensemble than for specific highlights.

Tokol Airbase

The former airbase in Tokol is today an active airport. The base used to be a major Soviet asset in the Cold War years, and home to a number of squadrons from the Soviet Air Force and the Soviet Army as well, operating everything ranging from helicopters up in size to transport aircraft. Its extensive premises have been divided, and the state is basically renting most of the hardware – including the former aircraft shelters and aprons – and land to a number of private enterprises, either connected with aviation or not.

The runway is still active for smaller general aviation aircraft, as you can see from the pictures. The place is really a suggestive scenario for pleasure flights, especially for history-fond pilots!

During our visit we had the chance to access some of the largest air shelters, built in the 1980s for aircraft the size of a MiG-29. There are at least five of them, along with more common and smaller ones.

Designed for the case of a scramble, these shelters allowed an aircraft to start its engines inside.

To this aim, the back of the shelter is not closed, but it features a large exhaust deflector tunnel, bent towards the side of the hangar, with a metal door closing it when not in use.

The front gate of the shelter is blast proof, an its thickness is actually really amazing!

The hangar we accesses shelters a couple of nice historic aircraft today. Traces of writings in Russian are a testimony of the previous owners.

Several abandoned buildings, including a rather large one with a small control tower, possibly from an older era – judging from the style similar to some German airfields from Hitler’s times (see this post).

One of the smaller shelters hosts another private enterprise, operating a unique airworthy Aero L-29 trainer from Soviet times. The same hangars offers a rich collection of Soviet signs on the walls.

Tokol features a number of older control towers – the reason is hard to guess…

Climbing one of them, we could get a very good view of the western part of the airfield, with many shelters around. Rather unexpectedly, the tower features an official writing in Chinese – maybe for potential Chinese customers?

Away from the runway, the airbase unfolds with a network of service roads and a number of buildings from Soviet times, today still in a very good shape, albeit shrouded by vegetation.

Getting there & Moving around

Tokol is an active airport, fenced and guarded. Getting in is basically not possible, unless you have a valid reason to enter. We had the chance to get in thanks to the invitation of the owner of the historical Aero L-29 mentioned above, who is also the tenant of the corresponding old aircraft shelter.

Basalt-Type Nuclear Storage on Kunmadaras Airbase

Kunmadaras used to be a major Soviet attack base in Hungary. The place was base for Sukhoi Su-17, Su-24 and MiG-27. This clearly justifies the construction of a Bazalt type storage, for aircraft-dropped nuclear weapons.

As the base is home to some residual, non-military activity and consequently at least lightly guarded, it may be interesting to concentrate on the most unusual nuclear bunker, located in an isolated spot, some .75 miles north of the runway and far from the most active areas.

The road connecting the airport to the bunker, detached in a fashion similar to other Soviet bases (see here and here for more examples), is today completely invaded by vegetation, leaving only a narrow passage to get access to the wide apron where the bunker entrance is located.

A loading platform for trucks can be spotted to the side of the shelter, ahead of the apron.

The six pillars, once covered with a roof and holding a crane for loading operations, are still prominently in place.

The entrance to the bunker is partly hidden by overgrown vegetation. The external curved tight door is gone, similar to the square shaped one deflecting side-ward and creating an airlock by the main entrance. Access is henceforth very easy.

To the side of the entrance corridor, the technical rooms have been spoiled of any hardware, yet the original paint is still in place, as well as writing in Russian. The metal staircase leading to the rooms for the air conditioning plant on the upper floor has been taken away, making the upper level inaccessible. Air conditioning was pivotal in nuclear storage bunkers, due to the need to store the warheads in specific temperature and humidity conditions.

Going further in, you finally get close to the gate of the storage chamber. The two halves of the massive curved tight door once closing the chamber have been taken from their posts and left on the ground. This provides a glimpse of the monster size of these blast-proof doors.

The chamber has turned very humid, and is totally dark. With the help of a torchlight or a camera flash, you can see the walls are still largely covered in their original coat, with painted frames and numbers possibly marking the position of fire extinguishers.

Electric line or pipeline holders painted in green can be found on one side. Also the pavement features a peculiar colored pattern, painted on a kind of linoleum, today covered in dust and dirt.

The concrete wall to the back of the chamber has been torn down, and some stones and land have come into the chamber. Bazalt type bunkers had only one main gate to the front.

Back out, to the north of the hangar, traces of the original barbed wire can be found in the impenetrable vegetation.

Going north from the shelter, pointing away from the base, you can get a distant view of conspicuous housing for the troops and their families – today completely abandoned.

Getting there and Moving around

As said, the main gate east of the base is guarded, as private companies have taken over part of the premises. However, the nuclear bunker is located north of the airfield, at a safe distance from the former airbase and the businesses going on there today. You may reach close to the base by car along an unpaved road used by local farmers, going parallel to the northern side of the base, keeping about 1 mile from it. This is not suitable for city cars though, so maybe you can stop when you feel appropriate, and go by foot.

To access the bunker area from the road (i.e. from north), you need to go through a field of turn-flowers. My advice is to go along the side of the bunker area to the south of it, and taking the old connection road going from the base to the bunker pointing north – trying to penetrate the area directly from north is made extremely difficult, due to the incredibly dense vegetation.

The area of the bunker is totally abandoned, so you can take your time when visiting the place.

Kalocsa Airfield & Anti-Aircraft Defense Area

Kalocsa airfield, located just northwest of the homonym village famous for the paprika business, was used by the Soviets as a helicopter base. Today, this relatively small airfield is very active with smaller general aviation flights and flight school activities, henceforth it cannot be toured freely.

However, to the northwestern corner, you may easily access the area of a former SAM base, likely put here to defend the airfield from air raids. The area features a number of small almost-circular embankments, with concrete platform at the center. This is where the missile would stand. Looking closely, you may see the concrete ducts for cables and pipes connecting the control trailer to each missile.

The area of the embankments is connected to an abandoned command building via a narrow paved road. To the western side of the building, traces of a small monument can be found.

Just south of the command building, a hangar made in 1970 – as the sign clearly says – is today used as a stable.

Getting there & Moving around

Access to the northwestern corner of the airfield is easy moving by car along an unpaved road going along the western side of the airport, and accessible from a public road running south of it. The area of the missiles is formally on the airport, so you should be careful not to interfere with any activity. More importantly, you are likely on a farmer’s land, so enter at your own risk.

Heviz Airport (formerly Sarmellek Airbase) and Granit-Type Bunker

What is today a small civil airport, surrounded by an array of rotting buildings, used to be a prominent Soviet air base, reportedly operating even the MiG-29 type in its heyday.

Being an active commercial airport, access to the air-side is not possible. Yet the premises of today’s airport are more modest in size than those of the original airbase. As a result, you may get access to a part of the former airbase without interfering with airport operations.

Many local businesses have taken over most of the former shelters for fighter aircraft.

Significant houses and garages, in the shabby pure-Soviet style, are now abandoned, and make for a creepy sight.

Going along a former service road, taking south from the control tower, you end up in the land of a farmer. Where the road ends, you can easily spot beyond the fence marking the current perimeter of the airport, the entrance and the typical round shape of a Granit bunker. The original metal door typical to this type is missing, or maybe it was never installed.

As said, Granit bunkers could be used for a variety of purposes, including storing command and control facilities, or as communication bunkers. The fact that the CIA listed this site as a nuclear depot may be also due to the fact that the Granit bunker made the place ‘nuclear-ready’.

Getting there & Moving around

As said, this is a commercial airport. The entrance to the former airbase gives access to the control tower as well as the small modern terminal area – a new building to the northeast of the runway. As said, the Granit bunker can be reached by taking the service road from the control tower to the south. This is surrounded by desolating dumps and half-demolished buildings. While technically out from the active airport area, you are still likely moving on private land, so enter at your own risk.

The Aeronautical Museum of Belgrade

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

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

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

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

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

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

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

Sights

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

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

Indoor exhibition

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Outdoor exhibition

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

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

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

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

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

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

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

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

Visiting

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

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

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