Kosmos 1481 (Russian:Космос 1481 meaningCosmos 1481) was a SovietUS-K missileearly warning satellite which was launched in 1983 as part of the Soviet military'sOko programme. The satellite was designed to identify missile launches usingoptical telescopes andinfrared sensors.[2]
Kosmos 1481 was launched fromSite 43/3 atPlesetsk Cosmodrome in the Russian SSR.[3] AMolniya-M carrier rocket with a2BL upper stage was used to perform the launch, which took place at 19:21 UTC on 8 July 1983.[3] The launch successfully placed the satellite into amolniya orbit. It subsequently received itsKosmos designation, and theinternational designator 1983-070A.[4] TheUnited States Space Command assigned it theSatellite Catalog Number 14182.[4]
This satellite did not reach its working orbit and self-destructed. As well as its main entry this satellite has catalogeddebris such as:

Kosmos 1481 was the 12th US-K satellite likeKosmos 862 to self-destruct, NASA believes intentionally. The event occurredwithin a day of launch. An expected orbital maneuver by Kosmos 1481 to move from its transfer orbit to an operational orbit about three days after launch was never performed.[5] All of its trackable debris is still in orbit.
