Kosmos 2133 (Russian: Космос 2133 meaning Cosmos 2133) is a Russian US-KMO missile early warning satellite which was launched in 1991 as part of the Russian Space Forces' Oko programme. The satellite is designed to identify missile launches using infrared telescopes.[1]
Kosmos 2133 was launched from Site 200/39 at Baikonur Cosmodrome in Kazakhstan. A Proton-K carrier rocket with a DM-2 upper stage was used to perform the launch, which took place at 08:31 UTC on 14 February 1991.[2] The launch successfully placed the satellite into geostationary orbit. It subsequently received its Kosmos designation, and the international designator 1991-010A.[2] The United States Space Command assigned it the Satellite Catalog Number 21111.[2][3]
Kosmos 2133 was the first satellite in the US-KMO series and was operational for over 4 years.[1][3]
