  • RT-2 Development of the RT-2, the Soviet Union's first solid propellant ICBM, was undertaken by Sergei Korolev and his successor from 1961-1968. It was a huge technical challenge, involving technology in which the Russians had no prior experience. The high-priority RT-2 preoccupied Korolev and his team throughout the period of the moon race, and could be considered a factor in the loss of that race to the Americans. In the end only sixty were deployed, but these provided the technical basis for Russian ballistic missiles of the 1980's and beyond. 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.
