Kosmos 2155 was launched from Site 81/23 at Baikonur Cosmodrome in Kazakhstan.[1] A Proton-K carrier rocket with a DM-2 upper stage was used to perform the launch, which took place at 17:51 UTC on 13 September 1991.[2][3] The launch successfully placed the satellite into geostationary orbit. It subsequently received its Kosmos designation, and the international designator 1991-064A.[2] The United States Space Command assigned it the Satellite Catalog Number 21702.[2][3]
It was operational for about 9 months.[3]
