Strategic communications missile. Year: 1979. Family: UR-100. Country: Ukraine. Article Number: 15A11. Alternate Designation: Perimeter. Complex: 15A11. Perimetr was a rocket developed for launch of a highly secret communications payload. This would be be put in orbit or on a long high-altitude trajectory to provide back-up command and control of the strategic forces in the event of nuclear war. A decree of 30 August 1974 authorised development under the supervision of Utkin at Yuzhnoye. The draft project for the new required factory test equipment was completed in December 1975, and that for the 15A11 rocket and its 15B99 payload in December 1977. Trials began in December 1979 and were completed in March 1982. The system entered service in January 1985 but was withdrawn by December 1990. The rocket was most likely based on Yuzhnoye's MR-UR-100, which would account for its rapid withdrawal from service after the collapse of the Soviet Union. Manufacturer: Yuzhnoye. Launches: 11. Failures: 1. Success Rate: 90.91%. First Launch Date: 1979-01-01. Last Launch Date: 1988-01-01. Launch data is: incomplete. Apogee: 1,000 km (600 mi). Liftoff Thrust: 1,236.000 kN (277,863 lbf). Total Mass: 71,000 kg (156,000 lb). Total Length: 21.60 m (70.80 ft).
