Associated Launch Vehicles
  • RT-20P Ukrainian intercontinental ballistic missile. Following the protracted development of Shavyrin's Gnom air-augmented ICBM, it was decided to let Yangel tackle the problem of developing a 30 tonne gross mass ICBM using more conventional technology. At first a three-stage solid propellant design was considered. But it was found impossible to achieve the launch weight with such an approach. Yangel's solution was to propose the only mixed propulsion ICBM ever developed - a solid propellant first stage, and high performance ampulised storable liquid propellant second stage. The draft project for the missile was completed in December 1964 and a decree to proceed with development was issued on 24 August 1965. Shortly thereafter Shavyrin died and Gnom was cancelled, leaving Yangel's RT-20P the lead project for the mobile ICBM requirement. Designs for silo-launched and submarine-launched versions of the missile were to be developed as well. More...
  • Temp-2S Russian intercontinental ballistic missile. World's first operational mobile ICBM. Deployed in greaty secrecy in 1976-1987 contrary to the terms of the SALT-2 Treaty. More...

Associated Launch Sites
  • Plesetsk Plesetsk was the Soviet Union's northern cosmodrome, used for polar orbit launches of mainly military satellites, and was at one time the busiest launch centre in the world. The collapse of the Soviet Union put the main launch site of Baikonur in Kazakh territory. It now seems that once the Proton rocket is retired, Baikonur will be abandoned and Plesetsk will be Russia's primary launch centre. Upgrades to existing launch facilities will allow advanced versions of the Soyuz rocket and the new Angara launch vehicle to be launched from Plesetsk. Plesetsk's major drawback was the lower net payload in geosynchronous orbit from a northern latitude launch site. However Russia is planning to remove the disadvantage by looping geosynchronous satellites around the moon, using lunar gravity to make the necessary orbital plane change. More...
