Kosmos 2393 (Russian: Космос 2393 meaning Cosmos 2393) is a Russian US-K missile early warning satellite which was launched in 2002 as part of the Russian Space Forces' Oko programme.[5] The satellite is designed to identify missile launches using optical telescopes and infrared sensors.[2]

Kosmos 2393 was launched from Site 16/2 at Plesetsk Cosmodrome in Russia.[7] A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 12:20 UTC on 24 December 2002.[3] The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 2002-059A.[3] The United States Space Command assigned it the Satellite Catalog Number 27613.[3]

It stopped undertaking maneuvers to remain in its orbital position in February 2007 which probably indicates that it was not working from that date.[4][5] It re-entered on December 22, 2013, according to one source.[8]
