Kosmos 1409 (Russian: Космос 1409 meaning Cosmos 1409) was a Soviet US-K missile early warning satellite which was launched in 1982 as part of the Soviet military's Oko programme. The satellite was designed to identify missile launches using optical telescopes and infrared sensors.[2]

Kosmos 1409 was launched from Site 16/2 at Plesetsk Cosmodrome in the Russian SSR.[3] A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 06:23 UTC on 22 September 1982.[3] The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1982-095A.[4] The United States Space Command assigned it the Satellite Catalog Number 13585.[4]

It re-entered the Earth's atmosphere on 8 June 2009.[4]
