Russia upgrades secret Ural bunker tied to ‘Dead Hand’ nuclear command system
Russia has carried out a massive expansion of a secret underground nuclear command complex in the Ural Mountains linked to the Soviet-era Perimetr retaliatory system, known in the West as the “Dead Hand,” according to a joint investigation by Danwatch, The Sunday Times and the Dossier Center.
In a joint investigation, Danwatch, The Sunday Times, and the Dossier Center revealed that Russia has significantly expanded a secret underground nuclear command complex in the Ural Mountains. The facility, known as Object 1335 and codenamed Grot, is buried in Mount Kosvinsky, Sverdlovsk Oblast. The complex is linked to the Soviet-era Perimetr retaliatory system, also referred to as the "Dead Hand."
The expansion, which included procurement orders between 2018 and August 2024, saw Russia order over 22,000 metric tons of steel, 170 kilometers of steel pipes, and 41,000 steel components. The project is believed to be connected to the modernization or reactivation of Perimetr. The construction involves at least 24 underground spaces connected to a compressed-air system, with a distance of around 2.5 kilometers between the main entrance and emergency exits.
The facility also includes earthquake-resistant and explosion-proof electrical equipment, as well as ventilation units designed to protect against chemical and biological agents. Western-made products, including insulation and valves, were also identified in the procurement documentation. While the presence of these products does not necessarily indicate a violation of sanctions, the investigation emphasizes the need to trace individual supply chains to determine legal responsibility.
