Kosmos 1629 (Russian: Космос 1629 meaning Cosmos 1629) is a Soviet US-KS missile early warning satellite which was launched in 1985 as part of the Oko programme. The satellite is designed to identify missile launches using optical telescopes and infrared sensors.^[1]

Kosmos 1629 was launched from Site 200/39 at Baikonur Cosmodrome in the Kazakh SSR.^[1] A Proton-K carrier rocket with a DM upper stage was used to perform the launch, which took place at 07:57 UTC on 21 February 1985.^[2][3] The launch successfully placed the satellite into geostationary orbit. It subsequently received its Kosmos designation, and the international designator 1985-016A.^[2] The United States Space Command assigned it the Satellite Catalog Number 15574.^[2][3]

It was operational for about 2 years.^[3]
