  • RT-15 Russian intermediate range ballistic missile. The RT-15 IRBM used the second and third stages if the RT-2 ICBM. After protracted development in 1961-1970 with a range of alternative self-propelled mobile launchers, limited numbers ('few' to 19) of two types of launchers were deployed in 1970. The various transporters tested created confusion in the West (with designations SS-14 Scapegoat and Scamp being applied). More...
  • RT-2P Russian intercontinental ballistic missile. Development of the improved RT-2P version of the basic missile was authorised by decree 1004-365 of 18 December 1968. The overriding concern was imminent deployment by the Americans of the Safeguard anti-ballistic missile system, and the need for the missile to have the necessary countermeasures to defeat those defences.

  • RT-2M Russian intercontinental ballistic missile. The RT-2M was a modernised RT-2, developed under Savodskiy at Korolev's bureau beginning in the late 1960's in parallel with the RT-2P and using alternate new engines. This increased both range and payload compared to the RT-20. However the RT-2P was selected for further development. More...

Associated Propellants
  • Solid Solid propellants have the fuel and oxidiser embedded in a rubbery matrix. They were developed to a high degree of perfection in the United States in the 1950's and 1960's. In Russia, development was slower, due to a lack of technical leadership in the area and rail handling problems. Solid propellants have the fuel and oxidiser embedded in a rubbery matrix.
