Plokstine – A Preserved Nuclear Missile Site in Lithuania

While almost all nuclear sites you can find in European Countries once beyond the Iron Curtain are today totally abandoned and fairly unaccessible, there exists a perhaps unique exception. The Plokstine site in northwestern Lithuania has been selected around 2010 for complete refurbishment with the help of public money, and in 2012 it has opened its doors as a museum. Located in a beautiful natural setting crowded with hikers – namely Zemaitija National Park, a national recreation area around Plateliai lake – it has quickly grown to international fame, and is now recording several thousands visitors per year, with guided tours in multiple languages – including English – offered on a regular basis during the warm season.

What is today an intriguing tourist destination, used to be part of a large Soviet installation for launching ballistic missiles armed with nuclear warheads. It is worth mentioning that Lithuania was a ‘Soviet Socialist Republic’ in the realm of the USSR, i.e. not just a satellite country of the Soviet Union, but part of it. Actually, this small country on the shores of the Baltic Sea, on the extreme western border of Soviet territory, was an ideal location for deploying weapons to hit European targets from within the Union. Furthermore, the Plokstine forest was – and still is – a little populated area, where construction works for a large top-secret military facility for storing and operating offensive cutting-edge hi-tech warfare would go likely unnoticed.

The missile complex was completed in December 1962, in the years of Khrushchev and Kennedy. The Plokstine site comprises of four interred silos and an extensive underground command station in the middle – the ensemble constituted a so-called ‘Dvina’ launch complex.

The ‘Dvina’ site in Plokstine was actually the last part of the missile base to be built. Two more sister surface sites, with four launchpads each, had been completed one year before, just west of the nearby village of Saiteikiai. These surface sites were similar to those you can find in Latvia (see this post), a neighbor country where unfortunately the last remaining ‘Dvina’ site was demolished in 2017, but abundant traces of the Soviet presence can still be found.

All three launch complexes in this region were designed around the R-12 missile. The R-12U missile was actually used in the underground ‘Dvina’ complex, slightly different from the surface-launched R-12. This weapon was better known by its NATO designation – SS-4 Sandal – and was a 2.3 megaton, single warhead, single stage nuclear missile. It reached true international notoriety before the base in Plokstine was activated, for this was the type deployed to Cuba in the missile crisis of 1962. Coincidentally, part of the staff transferred to Cuba in the days preceding the crisis was from the same rocket regiment of the Red Army (the 79th) stationed in Plokstine. Sandal missiles from here were reportedly transferred in complete secrecy to Cuba, via the port town of Sevastopol in Crimea in that occasion.

The base remained operational until the last missile – by then obsolete – left in 1978.

The Baltics were the first republics to leave the dying Soviet Union, openly defying the military authority of neighbor Russia. After the collapse of the Union and the end of communism in Europe, these three states – which historically do not belong to Russian culture – quickly joined the NATO and European Union, to escape Russian influence as much as possible. Most Soviet military installations were shut down and abandoned, and have been for two decades an interesting destination for explorers and war historians (see this post for many examples). Later on, most sites have been slowly demolished or converted into something else. Really a few of them have been preserved for posterity.

In this post you can find photographs from the Cold War Museum now open in the former ‘Dvina’ site of Plokstine, from a visit in 2017. Close to the bottom, you can find a few further photographs from a previous visit made by appointment in 2009, before the site was selected for renovation – these may be more appealing for Soviet-aura lovers!

Sights

What can be visited today is all in the area of the old ‘Dvina’ complex. The complex is mainly composed of four interred silos, covered by heavy steel & concrete bulged covers, placed on the four corners of a square. These gigantic caps are the most prominent components of the site from the outside. Today, an observation deck has been erected on the south of the area. From there, you can appreciate the distinctive plan of the ‘Dvina’ complex, with an access road terminating in a loop touching all four armored silo covers.

The weight of each cover is told to be around 100 tonnes, as it was armored to withstand a nuclear explosion. The covers would be pulled sideward with a sled mechanism, to open the silos before launch. Unmovable missile launch complexes, like the ‘Dvina’ site in Plokstine, were easy and attractive targets for western weapons, thus requiring a very strong defense barrier. Similar considerations led the design of the Titan missile sites in the US, which albeit more powerful and capable of a greater range, are roughly from the same era (see this post).

To get near the silos or get access to the museum, you need to pay a ticket and join a guided tour. The visit includes a tour of the Cold War Museum, which has been prepared inside the rooms of the former control center. The tour will start from the visitor center, a new modern building. You will soon go through a specimen of the original fences which ran around the ‘Dvina’ complex, and which included barbed wire and high-voltage electrified lines. Close by, you can find traces of original unarmored constructions, likely service buildings. The missile site was operated by more than 300 troops stationing in a number of smaller centers in the area around the complex.

The guide will lead you along a walk around the surface part of the complex, where you can see the construction of the caps from very close. The metal part is very rusty, but the concrete cover has been refurbished and looks like new – a pretty unusual sight, for connoisseurs of Soviet military relics!

Access to the underground missile service and control center is via a small metal door, right in the middle of the square formed by the four silos.

A few rooms in the control center today host the exhibitions of the Cold War Museum. A room displays a quick time-line of the Cold War, since the end of WWII to the end of the USSR. In the adjoining rooms you can find propaganda items

Another room is about defense against nuclear threat. This is interesting, with many artifacts like dosimeters and medical tools, plus easily readable instructions of ‘dos and don’ts’ in case of nuclear attack.

Another room is about the evolution of weapons over the Cold War decades, with original material from the time, including heavier tactical weapons.

The exhibition is modern, small but not superficial, and may appeal to any public, including children. Besides the exhibits, you can appreciate the relatively small size of all rooms and connecting corridors in the former control center.

As you are driven next to the missile operation part, you can find a scale model of the ‘Dvina’ complex and a cut-out of a R-12U silo, together with a map of the relatively few missile sites in Lithuania – from the map, it can be argued that, for some reason, many more sites were prepared in nearby Latvia.

Resting quarters for the troops and a communication station with original electronic gear have been reconstructed based on original footage and pics. Communication with the military headquarters was clearly an essential task – it was the only way an order to launch could be issued – and the serviceman on duty was responsible for assuring a permanent link with the chain of command. In other words, he was instructed not to leave his headphones under any circumstances, during a several hours-long shift!

On the sides of the corridors you can see holes for the extensive network of cables and pipes. Further on, you meet the most ‘hardware’ part of the exhibition. First, the original diesel-fueled power generator has been refurbished and is standing in its original room. The underground complex was designed not only to withstand a nuclear blast, but also to provide shelter for all servicemen for several days following an attack. This meant air filters, food, water, technical supplies and of course electrical power, were all essential assets. Oil for the generator was stored in a container in an adjoining room.

Finally, you get access to one of the four silos. You need to go through a tight door opened on the wall of the concrete structure of the control center. Writings in Cyrillic can be spotted on the walls in this area. From there, you will see the cylindrical shape of the metal structure of the silo from the side. This metal canister is really big, the ‘Dvina’ silos featured a much greater diameter than the SS-4 missile they were built for. This was somewhat different from their US counterpart (see this post), where the missile diameter fits the size of the silo without much margin.

You can get access to the silo via the original hatch, cut in the metal wall close to the rim on top of the silo, just beneath the external cap. Going through this hatch is incredibly difficult – it is extremely narrow, much longer than the size of a human step, and tilted upwards! It is hard to understand why the Soviets built it in a size so small – this applies to the control center too, for all corridors are really narrow and the ceiling in the rooms is so low you may easily need to bend forward! For those who don’t want to try the original entry to the silo, there is now a non-original door cut in the side of the canister.

The inside of the silo can be observed from an original service deck, immediately under the external cover. From here you can clearly appreciate the size of the construction – the missile was more than 70 ft long, and sat here in a vertical position. The SS-4 was among the first missiles to make use of a storable liquid propellant, which allowed it to stay in almost-launch-ready conditions for a prolonged time, if resting in a silo. Nonetheless, the time for opening the armored caps was about 30 minutes, which meant this was not exactly quick to launch. The understructure of the armored caps can be clearly appreciated from inside the silo.

Photographs Before Restoration Works – Ghost Base

When I visited this site for the first time in 2009, it was open only by appointment. Unfortunately, I had only a compact camera at the time, and the very low light inside plus a rainy day outside, meant I could take only a few acceptable pictures.

However, they provide an idea of the state of the ‘Dvina’ complex before it was decided to reconfigure it as a museum.

As you can see, the armored silo caps were in a worse shape than today, yet not heavily damaged. The barbed wire fence around the four silos was probably original Soviet.
