Ukrainian orbital launch vehicle. A government decree of 24 August 1965 ordered development by Yangel of a version of his R-36 rocket to orbit Chelomei's IS (Istrebitel Sputnik) ASAT and US (Upravlenniye Sputnik) naval intelligence satellites. The Tyklon 2 definitive operational version replaced the 11K67 launch vehicle from 1969 and was an adaptation of the 8K69 (SS-9) two stage ICBM. The IS and US Raketoplan-derived payloads had their own engines for insertion into final orbit.

  • 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...

It was also universally referred to as Tyuratam by both Soviet military staff and engineers, and the US intelligence agencies.
