  • Tsiklon The R-36 ICBM was the largest ever built and the bogeyman of the Pentagon throughout the Cold War. Dubbed the 'city buster', the 308 silos built were constantly held up by the US Air Force as an awesome threat that justified a new round of American missile or anti-missile systems. On the other hand, the Americans were never motivated to build and deploy corresponding numbers of their equivalent, the liquid propellant Titan 2. Derivatives of the R-36 included the R-36-O orbital bombing system, the Tsiklon-2 and -3 medium orbital launch vehicles, and the replacement R-36M missiles. With the collapse of the Soviet Union, the design and manufacturing facility ended up in independent Ukraine. Accordingly the missile was finally retired in the 1990's, conveniently in accordance with arms reduction agreements with the Americans. 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.
