Summary
US-KS 5 launched on a Soviet Space Program Proton K/DM-2 from 81/23 (81L), Baikonur Cosmodrome, Republic of Kazakhstan on September 13, 1991. It was Soviet Space Program's 2,440th launch, 45th this year and humanity's 3,664th orbital launch attempt. It was the 51st Proton K/DM-2 flight and the 5th this year. The payload was bound for Geostationary Orbit (Direct-GEO). The tracked orbit of Kosmos-2155, one of 6 catalogued objects, from September 18, 1991, was 35,781 × 35,911 km inclined 1.3°. 6 objects from this launch are catalogued, one of them a payload.
