Family: Tsyklon. Country: Ukraine. Status: Hardware. Other Designations: FOBS; Fractional Orbital Bombing System. Library of Congress Designation: F-1r. Department of Defence Designation: SS-9 Mod.3. ASCC Reporting Name: Scarp. Article Number: 8K69. Manufacturer's Designation: R-36-O.

The Global Rocket 1 (GR-1) requirement of 1961 called for a system to place a large nuclear warhead equipped with a deorbit rocket stage into a low earth orbit of 150 km altitude. The warhead could approach the United States from any direction, below missile tracking radar, so little warning was available. Not only could such a missile hit any point on earth, but the enemy would also be uncertain when it would be deorbited onto target. The main disadvantage was lower accuracy of the warhead in comparison to an ICBM.

Chelomei proposed his UR-200 for the requirement, while Yangel offered the R-36, and Korolev the 8K713. Development problems with the 8K713ís NK-9 engine resulted in continual delays, resulting in cancellation of Korolevís competitor in 1964. Following Khrushchevís ouster from power in October 1964, Chelomeiís UR-200 project was reviewed and cancelled. This left Yangelís R-36 for the mission.

Flight trials of the system were conducted 1965 to 1972. Since orbiting of nuclear weapons was a violation of international treaty, the Soviet Union conducted all tests on a 'fractional orbit' basis - i.e. the test warheads were deorbited after less than one orbit of the earth. The system was in service at 18 siloes at Baikonur from 1969 to 1983.
