MR-UR-100 intercontinental ballistic missile capable of carrying up to 4 warheads was under development at KB Yuzhnoe design bureau in Dnepropetrovsk beginning in 1970. The test launches of the missile started in Baikonur in 1972. Total 40 launches (of them 7 unsuccessful), were conducted until 1975, when the missile was accepted into the armaments of the Soviet Strategic Missile Forces, RVSN.
