Kosmos 2155 was launched from Site 200/40 at Baikonur Cosmodrome in the Kazakh SSR.[1] A Proton-K carrier rocket with a DM-2 upper stage was used to perform the launch, which took place at 15:15 UTC on 28 October 1987.[2][3] The launch successfully placed the satellite into geostationary orbit. It subsequently received its Kosmos designation, and the international designator 1987-091A.[2] The United States Space Command assigned it the Satellite Catalog Number 18443.[2][3]
It was operational for about 2 years.[3]
