Part of an investigation
This article is a part of the investigation The Nuclear Files
- Through systematic research in open-source databases, Danwatch has collected more than two million documents linked to Russian military procurement.
- The trove of documents contains hundreds of original blueprints detailing the layout of several Strategic Missile Forces bases across Russia.
Among the documents are hundreds of original floor plans of Strategic Missile Forces bases across Russia. - It offers unprecedented insight into President Putin’s massive modernization of some of the world’s most highly secured nuclear weapons facilities — a process in which several Western companies turns out to have played a key role.
If you have a tip about Danish or European companies in Russia, we would love to hear from you.
A very satisfied Vladimir Putin presented Russia’s progress in the modernization of its nuclear weapons program on 11 June in the Kremlin. According to the president, virtually all of the old nuclear weapons systems from the Soviet era have now been replaced with new ones.
“Currently, the share of modern weapons and technology in the strategic nuclear forces already makes up 95 percent. This good indicator, in fact, it is the highest indicator of all nuclear powers of the world,” he said.
And these are not just empty words from Putin.
Danwatch has systematically collected more than two million documents from Russian military procurement, revealing a massive upgrade of the military infrastructure at Russia’s most protected nuclear weapons facilities.
In addition to tender documents, the files also contain hundreds of highly sensitive original blueprints of bases belonging to Russia’s nuclear forces. The fact that these documents have been freely available on the Internet is considered to be a major security breach on the Russian side by several experts.
Recently, Danwatch, in collaboration with Germany’s Der Spiegel, uncovered previously unknown blueprints and military tender documents revealing how Russia has undertaken a massive modernization of the Strategic Missile Forces’ bases near the city of Yasny.
It was also documented that products from Danfoss, Grundfos and Rockwool, as well as companies from many other European countries, had been used in the upgrade of the bases, which at the time were being prepared to be equipped with Avangard – one of Russia’s newest nuclear weapons delivery systems.
Now Danwatch can reveal that the central technical base in Yasny, where the missile forces store the nuclear warheads in underground bunkers and where the missiles themselves are handled, has also been extensively upgraded.


Like “gold dust” to foreign adversaries
According to the extensive material, the base has been expanded and modernized several times since 2013. The area of the base has been expanded by almost 50 percent and is now equivalent to approximately 250 soccer fields, numerous new buildings have been erected, and extensive security systems and checkpoints have been installed on the base.
For the first time, Danwatch is now able to use detailed blueprints to look inside at least nine of the new buildings to determine what the buildings are used for and see in great detail how they are constructed. These include guardhouses, technical checkpoints and storage facilities for military equipment.
The blueprints also reveal more sensitive buildings, including a large assembly hall located in the area of the base where nuclear missiles are assembled and prepared before launch. The drawings show in great detail the layout of the hall and what materials are used.
According to Philip Ingram, a former military intelligence officer with more than 25 years’ experience in the British Army, the fact that these plans have been on the internet is further proof that the Russian authorities have been lax in the security of the highly sensitive nuclear weapons bases.
“This type of information is gold dust and can be compared to current satellite imagery to give a very current understanding of potential military targets,” he says.
“Understanding what buildings do or what they store is critical to modern military operations. It allows surgical attacks to have maximum impact, thereby reducing the risk to attacking forces and reducing collateral damage ,” he says.

Danish products
The tender documents also state that from 2013 to 2016 alone during the first phase of reconstruction, over 500 tons of rebar, 2,100 tons of cement and over 150 kilometers of cables were used to modernize the technical base. Explosion-proof equipment was also installed in several of the buildings.
In addition to several large Western companies from Germany, France, Italy, the Netherlands and Switzerland, products from Danish companies Rockwool, Danfoss and Grundfos have also been specifically requested and used.
The blueprints show that specific Rockwool products are written into the original drawings of at least five of the new buildings on the base. In some cases, contact details for Rockwool’s offices in Russia are also written in.
In total, Danwatch can document that at least 438 Danfoss components, 4 Grundfos pumps, and Rockwool ceiling and wall insulation products as well as almost 1 kilometer of pipe insulation were delivered. According to the documents, the products were used in several of the new buildings on the base, including the assembly hall, which currently contain products from Rockwool and Danfoss.
The Danish products have been requested by the Russian Ministry of Defense and delivered by Russian intermediaries in the years 2019-2020.
METHODOLOGY
How we connected the Avangard weapon system to the facility
According to the Russian Ministry of Defense and several of the world’s leading researchers monitoring the world’s nuclear forces, two regiments at Yasny have since 2019 been equipped with Avangard – one of Putin’s newest nuclear weapons delivery systems.
By analyzing several videos showing Avangard test launches published by Russia’s Ministry of Defense, we can confirm that the missiles and the Avangard system are indeed housed inside the technical base. In the videos, a missile is rolled out of a building and then heads towards a missile silo a few kilometers away.
Although great care has been taken to film very closely and not reveal too much detail in the videos, there are still some sequences that contain clues. By comparing visual markers such as buildings, trees, masts and roads with satellite images of the area, it is possible to see exactly which route the vehicles in the video are taking and from which specific building the missile is brought out from.
This allows us to place the missile, which according to Russia itself is equipped with the Avangard system and which will be lowered into a missile silo and fired shortly afterwards, on the technical base. The silo itself can also be geolocated in the same way.

Denies any knowledge of deliveries
Danwatch has asked Danfoss, Rockwool and Grundfos about the deliveries to the technical base in Yasny. Rockwool and Grundfos refer to the answers they have previously given regarding the deliveries to the regiments’ bases and missile silos, while Danfoss has not responded to our inquiry.
From Rockwool’s headquarters in Hedehusene, Denmark, it was previously stated that Rockwool in Russia does not sell directly to Russian end users and therefore has no customer relationship with the Russian military, the Russian government, or other Russian public entities.
“Our products are widely available in both the Russian and Ukrainian markets through distributors. Therefore, it is also impossible for us to know or have any control over who all the end users in the Russian market are.”
Danfoss’ Head of Communications, Kasper Elbjørn, previously responded in an email:
“Danfoss no longer sells products on the Russian market and we have no contact with our former colleagues or former distributors.”
“I can’t deny that back in 2019 we sold, for example, thermostats or valves for water through various distributors,” he wrote, adding:
“We cannot help you further, but perhaps you should know that the valves our distributors sold are used to secure hot water in buildings and are hardly essential for the modernization you write about, which we therefore do not know about.”
Grundfos emphasized that the company has sold the Russian business in 2022 and therefore no longer has access to the Russian company’s archives and data.
“Jeres spørgsmål vedrører perioden fra 2017-2020. Derfor kan vi hverken af- eller bekræfte, om vores produkter, via lokale distributører, er tilbudt til eller solgt til modernisering af basen i Yasny. Men vi kan som jer se, at de har fremgået som referenceprodukter i udbudsmaterialet”, skrev Grundfos og uddybede:
“If you look at the list of products that according to your information were sold to the Yasny base, they were not covered by sanctions at the time. Nor were they developed for military purposes. These were basic water solutions for buildings. They are standard products that are normally sold for stock at retailers, which is why we normally have no knowledge of who the end users are.”
Danwatch has asked the Russian Ministry of Defense whether it has been in dialogue with Danish companies regarding the products used at the technical base in Yasny. We have also presented experts’ assessment that there is a major security breach in that Danwatch has been able to find the blueprints of sensitive nuclear weapons bases online.
However, they have not responded to our inquiry.
