Kosmos 2440 (Russian: Космос 2440 meaning Cosmos 2440) is a Russian US-KMO missile early warning satellite which was launched in 2008 as part of the Russian Space Forces' Oko programme. The satellite is designed to identify missile launches using infrared telescopes.[2] It spent its two year operational life at 80E giving early warning coverage of Russia, China, North Korea, the Middle East and some of Europe.[4]

Kosmos 2440 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 23:59 UTC on 26 June 2008.[2][5] The launch successfully placed the satellite into geostationary orbit. It subsequently received its Kosmos designation, and the international designator 2008-033A.[2] The United States Space Command assigned it the Satellite Catalog Number 33108.[2]

When the satellite was launched US-KMO satellite Kosmos 2379 was also operational although this failed late 2009/early 2010 after an 8 year life.[4] Kosmos 2440 itself started drifting off station in February 2010 giving an operational life of less than two years.[3][4]

Kosmos 2440 was replaced by Kosmos 2479 which was launched in March 2012.[6]
