RSD-10 Pioneer

The RSD-10 Pioneer (Medium-Range Missile "Pioneer") was a medium-range ballistic missile with a nuclear warhead deployed by the Soviet Union from 1976 to 1988. It carried GRAU designation 15Zh45. Its NATO reporting name was SS-20 Saber. It was withdrawn from service under the Intermediate-Range Nuclear Forces Treaty.

The missile was 16.5 m high, 1.79 m in diameter and weighed 37.1 tons. It was based on two solid-fuel fibre-glass clad stages of the RT-21 Temp 2S (SS-16 Sinner) so it was also known as the RT-21M Pioneer. The missile's range was from 600 to 5,000 km initially; the final model had a maximum range of possibly 7,500 km. Initially the missile was fitted with a single 1 MT, 1.6 ton warhead, later models could take one warhead or two and from 1980 three MIRV'd 150 KT devices (Pioneer UTTH). The CEP was also reduced from 550 metres to 150-450 meters.

It was intended to replace, or augment, the R-12 Dvina (SS-4 Sandal) and R-14 Chusovaya (SS-5 Skean) missiles deployed from 1958 and 1961 respectively in the USSR and Warsaw Pact states. It entered the development stage in 1966 and a design concept was approved in 1968 and the task given to the Moscow Institute of Thermal Technology and Alexander Nadiradze. Flight testing began in 1974 and deployment commenced on March 11, 1976, with the first supplied units becoming operational in August of that year. Up to 1986 a total of 48 launch sites, including a site at Pavschino, were equipped with 405 RSD-10 missiles.

The Warsaw Pact enjoyed in Central Europe a massive conventional superiority over NATO. Warsaw Pact forces assumed that NATO would use Theater Nuclear Forces to stop a massive conventional Soviet offensive. The RSD-10 provided the Soviet Union with an in-theater "selective" targeting capability that it previously had lacked. The RSD-10 had the capacity to destroy virtually every NATO base, weapons storage site with negligible warning. Thus, the Soviet Union acquired the capability to neutralise NATO tactical nuclear forces with surgical nuclear strikes.

The United States deployed Pershing II and Tomahawk missiles in Western Europe in attempt to counter the RSD-10.

654 missiles were built in total. These and the 499 associated mobile launchers were destroyed by May 1991 in accordance with the Intermediate-Range Nuclear Forces Treaty. Fifteen SS-20 and Pershing II are preserved to commemorate this agreement. One RSD-10 can be seen in the grounds of the Museum of the Great Patriotic War, Kiev, Ukraine, and another is inside the Smithsonian National Air and Space Museum at Washington, D.C..
