Special Control Service
Identity
Open sources match this record to the Russian Ministry of Defence Special Control Service (SSK), military unit 46179, within the 12th Main Directorate. EGRUL-derived registry data place unit 46179 at 2 Rubtsovsko-Dvortsovaya Street, Sokolniki, Moscow. MoD-linked reporting in May 2018 marked the service’s 60th anniversary, consistent with a 1958 origin.

Mission
MoD statements describe SSK’s core tasks as detecting foreign nuclear tests, monitoring compliance with treaties limiting or banning nuclear testing, supporting Russia’s participation in the CTBT verification regime, tracking global seismic and radiological conditions, monitoring nuclear accidents within the technical limits of its sensors, and participating in geophysical monitoring over Russia.

Verification role
In September 2022, the head of 12 GUMO said the MoD had served as Russia’s national authority for CTBT implementation since 2004 and that these functions are carried out inside the ministry by SSK. CTBTO records list 32 Russian IMS facilities: 6 primary seismic stations, 13 auxiliary seismic stations, 8 radionuclide stations, 4 infrasound stations, and 1 radionuclide laboratory in Moscow (RL13).

Network context
Several associated placemarks align closely with CTBTO-listed Russian monitoring nodes at Zalesovo, Kirov, Peleduy, Bilibino, Petropavlovsk-Kamchatskiy, Ussuriysk/Grigoryevka, and Yuzhno-Sakhalinsk. That pattern is consistent with unit 46179 being tied to a geographically dispersed monitoring network rather than operating solely from the Moscow address. Exact one-to-one matching of every placemark to current SSK subunits is not publicly confirmed.

Site assessment
On 1 July 2022, duty shifts of the newly formed Main Center for Geophysical Monitoring under SSK began round-the-clock operations. According to 12 GUMO, the center was created to process large volumes of multi-source data, register nuclear explosions worldwide, and identify technogenic geophysical disturbances. Open sources do not publicly describe the internal layout at 2 Rubtsovsko-Dvortsovaya Street or confirm any warhead-storage role there; the available evidence supports an administrative and coordination function for the Moscow site.
