Profile summary

Assessment

Identification

Placemark 3 matches the open-source Kolosovka/Kulikovo complex in Zelenogradsky District, Kaliningrad Oblast, long assessed as a probable base-level nuclear warhead storage site; the FAS 2012 study placed that facility at 54°50'12.51"N, 20°21'12.82"E, essentially the same location as the placemark. Nearby placemark 2 is consistent with the associated Kolosovka garrison/support area used by military unit 20336. Placemark 1 is most plausibly the Gornyy/Chita-46 base-level storage site in Zabaykalsky Krai, but that attribution is less certain in public sources.

Kaliningrad depot

FAS described the Kaliningrad site as a possible nuclear warhead storage facility about 17 km northwest of Kaliningrad city and roughly five miles from Chkalovsk Air Base, with three apparent igloos inside a double-fenced compound and at least one triple-fenced inner security area. Russianforces later identified Kolosovka as the base-level facility that can store nuclear weapons for nuclear-capable delivery systems in the Kaliningrad region.

Unit 20336

Official Russian municipal and civil-aviation records place military unit 20336 in Kolosovka, including premises on Tsentralnaya Street and a flight-restriction contact address at Tsentralnaya-4. This supports reading placemark 2 as the administrative or support component of the wider Kolosovka-Kulikovo complex rather than as a separately confirmed bunker area.

Recent observable changes

Recent open-source reporting says the Kaliningrad storage site has undergone further reconstruction and additional fencing by 2025, while the Bulletin’s 2025 Europe survey explicitly lists Kulikovo, Kaliningrad Oblast, as a nuclear weapons storage site. These sources support continued maintenance and hardening of the site’s storage infrastructure, but they do not publicly confirm that warheads are currently present there.

Gorny site

For placemark 1, the best public match is the Gornyy/Chita-46 site near Gorny, Zabaykalsky Krai. Russianforces identifies Chita-46 as co-located with the Gornyy base-level storage and notes that the site’s exact mission is not entirely clear, although it had earlier Strategic Rocket Forces ties. Separately, current order-of-battle work places the 3rd Missile Brigade at Gorny, and the 2025 Nuclear Notebook reports major upgrades around that brigade plus Iskander launchers and/or transporters observed near a nearby air-force nuclear weapons storage site in March 2024. A support relationship to the 3rd Missile Brigade is therefore plausible, but not publicly confirmed. ([russianforces.org](https://russianforces.org/blog/2017/08/where_the_weapons_are.shtml))
