Perimetr 15A11


Ukrainian strategic communications missile. Perimetr was 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 The system entered service in January 1985 but was withdrawn by December 1990.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.

The competing design of Chelomei, the UR-100N, was also put into production when the Soviet hierarchy deadlocked and could not pick one design over the other. More...

Associated Launch Sites
  • Baikonur Russia's largest cosmodrome, the only one used for manned launches and with facilities for the larger Proton, N1, and Energia launch vehicles. The spaceport ended up on foreign soil after the break-up of Soviet Union. The official designations NIIP-5 and GIK-5 are used in official Soviet histories. It was also universally referred to as Tyuratam by both Soviet military staff and engineers, and the US intelligence agencies. Since the dissolution of the Soviet Union the Russian Federation has insisted on continued use of the old Soviet 'public' name of Baikonur. In its Kazakh (Kazak) version this is rendered Baykonur.
