Kosmos 1849 (Russian: Космос 1849 meaning Cosmos 1849) is a Soviet US-K missile early warning satellite which was launched in 1987 as part of the Soviet military's Oko programme. The satellite is designed to identify missile launches using optical telescopes and infrared sensors.[2]

Kosmos 1849 was launched from Site 16/2 at Plesetsk Cosmodrome in the Russian SSR.[5] A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 18:50 UTC on 4 June 1987.[3] The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1987-048A.[3] The United States Space Command assigned it the Satellite Catalog Number 18083.[3]

It re-entered the Earth's atmosphere on 3 February 2003.[4]
