4th State Central Interspecific Test Site (Kapustin Yar)
Identification
The supplied coordinates and placemark naming are consistent with the Kapustin Yar missile test complex in Astrakhan Oblast, whose administrative-residential center is Znamensk. U.S. government historical material identifies Kapustin Yar as State Central Rocket Testing Range No. 4, created in 1946, and notes the first rocket launch there occurred on 18 October 1947.

Mission
Russian Defense Ministry reporting describes Kapustin Yar as a multiservice research and test complex. In 2020 the ministry said its structure included research and testing units for the Strategic Missile Force, missile troops and artillery, air defense forces, aerospace force, land troops, and the Sary-Shagan practice range in Kazakhstan; UNIDIR’s 2024 New START reference also lists Kapustin Yar as one of Russia’s two main ICBM test ranges.

Instrumentation
Kapustin Yar is an instrumented range with specialized measurement infrastructure. Russian reporting says its data-acquisition and management systems allow testing of ballistic-missile combat equipment under varied conditions, and that modernization of the measuring complex enabled real-time transmission of pre-launch and flight data to the Strategic Missile Force command post with greater automation. Despite historic space launches, range leadership said in 2017 there were no plans to convert it into a replacement space center. ([tass.com](https://tass.com/russia/713238))
Observed activity
Open-source official reporting ties the site to strategic and theater missile work: a Strategic Missile Forces ICBM launch was publicly announced from Kapustin Yar on 11 April 2023 and landed at Sary-Shagan; earlier reporting linked the range to Iskander missile trials, S-400 40N6E state trials, and S-500 live firing. This pattern is consistent with a broad weapons-evaluation mission rather than a single-service training base. ([tass.com](https://tass.com/defense/1602869))
Current relevance
Kapustin Yar has direct relevance to the Russia-Ukraine war, although some specifics remain claim-based. AP reported that Ukraine’s military intelligence identified the site as the launch point for the 21 November 2024 Oreshnik strike on Dnipro, and Reuters reported on 5 February 2026 that Ukraine claimed successful January strikes on hangar-type buildings at Kapustin Yar used for pre-launch preparation of intermediate-range and intercontinental ballistic missiles; the full extent of damage has not been publicly confirmed.
