NSSDCA/COSPAR ID: 1967-005A
Cosmos 139 was a Soviet military FOBS satellite launched from the Baikonur cosmodrome aboard an Tsiklon rocket. The Soviet-built fractional orbit bombardment system (FOBS) allowed missiles or warheads to remain in earth orbit before beginning their descent. FOBS gave the USSR the ability to launch a mass attack against the U.S. from any direction rather than just depending on a ballistic pathway arching over the North Pole.
