Korolev studied this Multimodular Rocket (MR), based on stages already designed for the 8K74 and 8K77 (R-7 and R-9) missiles. The concept seems to have been promoted in competition with Chelomei's UR-200, for the launcher could be used for similar missions:
As was the case of the 8K74, work on the design was stopped in September 1961.
Liftoff Thrust: 140,000 kgf. Total Mass: 101,000 kg.
From 1960 to 1961 Korolev's design bureau worked on the single stage 8K79 military rocket. The 25 tonne missile could hurl an 800 kg warhead over a 2300 km range. A competing missile was selected for the requirement. Korolev's MR was based on stages already designed for the 8K74 and 8K77 missiles. The three-stage space launch version of the rocket would have a total mass of 101 tonnes; an ICBM version would be composed of just the first and second stages, and an IRBM version from the first stage alone.
