Kosmos 2397 (Russian: Космос 2397 meaning Cosmos 2397) is a Russian US-KMO missile early warning satellite which was launched in 2003 as part of the Russian Space Forces' Oko programme. The satellite is designed to identify missile launches using infrared telescopes.[2]

Kosmos 2397 was launched from Site 81/24 at Baikonur Cosmodrome in Kazakhstan. A Proton-K carrier rocket with a DM-2 upper stage was used to perform the launch, which took place at 04:23 UTC on 24 April 2003.[2] The launch successfully placed the satellite into geostationary orbit. It subsequently received its Kosmos designation, and the international designator 2003-015A.[2] The United States Space Command assigned it the Satellite Catalog Number 27775.[2]

The satellite developed problems two months after being launched. It started drifting eastwards in June 2003 and had reached 155E by November 2003.[3]
