The R-36 is a family of intercontinental ballistic missiles (ICBMs) and space launch vehicles designed by the Soviet Union during the Cold War. The original R-36 was deployed under the GRAU index 8K67 and was given the NATO reporting name SS-9 Scarp. It was able to carry three warheads and was the first Soviet MIRV missile. The later version, the R-36M, also known as RS20, was produced under the GRAU designations 15A14 and 15A18 and was given the NATO reporting name SS-18 Satan. Some R-36 missiles have been converted into Tsyklon family launch vehicles, and some R-36MUTTKh missiles have been converted into Dnepr medium-lift launch vehicles, capable of putting up to 4,500 kg into orbit. However, neither launch vehicles remain active, with the Tsyklon-4 being cancelled in 2023.
