Kosmos 2176 (Russian: Космос 2176 meaning Cosmos 2176) was a Russian US-K early warning satellite [6] which was launched in 1992 as part of the Russian Space Forces' Oko programme. The satellite was designed to identify missile launches using optical telescopes and infrared sensors.[2]

Kosmos 2176 was launched from Site 43/3 at Plesetsk Cosmodrome in Russia.[7] A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 01:18 UTC on 24 January 1992.[3] The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1992-003A.[3] The United States Space Command assigned it the Satellite Catalog Number 21847.[3]

It re-entered the Earth's atmosphere on January 17, 2012.[4]
