ЖБОТ Си-11 is a Soviet-era military bunker complex located in the southern Ural Mountains region of Russia, near the town of Yasny. This area is identified as one of eleven primary land-based intercontinental ballistic missile (ICBM) launch sites comprising a core component of Russia's nuclear triad. The facility is part of the broader Russian Nuclear Weapons Complex, representing the hardened, buried infrastructure designed to protect nuclear missiles and their support systems during the Cold War.
The specific designation 'ЖБОТ' (Zhelezobetonnaya Ognennaya Tochka) translates to 'reinforced concrete firing point,' indicating its function as a fortified position within a larger missile field. Current photographic evidence and leaked documents have highlighted the area around Yasny as containing some of the world's most heavily protected missile silos, capable of launching missiles carrying some of the largest nuclear warheads in existence.
The site's precise operational status is not detailed in public sources, but its historical role as a key element of strategic deterrence is well-established through analyses of Russia's nuclear infrastructure.
