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.[4] Kosmos 1409 replaced Kosmos 1217 as part of the Oko constellation of satellites and covered the plane 2 - 317° longitude of ascending node.[5]

Mission

The satellite was designed to identify missile launches using optical telescopes and infrared sensors.[4]

Launch

Kosmos 1409 was launched from Site 16/2 from Plesetsk Cosmodrome in Soviet Union.[2] A Molniya-M launch vehicle with a Blok 2BL upper stage was used to perform the launch, which took place at 06:23:11 UTC on 22 September 1982.[2] The launch successfully placed the satellite into a Molniya orbit. It subsequently received its Kosmos designation, and the COSPAR International Designator 1982-095A.[6] The United States Space Command assigned it the Satellite Catalog Number 13585.[6]
