SS-20 Pioneer and Pershing II
Russian and US ballistic missiles, banned by the SALT II treaty.
The RSD-10 Pioneer (SS-20 Saber) was an intermediate-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.
Its deployment was a major cause of the NATO's 'Double-Track
Decision', which led to the deployment of more medium-range nuclear
weapons in Western Europe. The RSD-10 was withdrawn from service under
the 1987 Intermediate-Range Nuclear Forces Treaty.
The Pershing II Weapon System was a solid-fueled two-stage
ballistic missile designed and built by Martin Marietta to replace the
Pershing 1a Field Artillery Missile System as the United States Army's
primary nuclear-capable theater-level weapon. The U.S. Army
replaced the Pershing 1a with the Pershing II Weapon System in 1983
while the German Air Force retained Pershing 1a until all Pershings
were eliminated in 1991. The U.S. Army Missile Command (MICOM) managed
the development and improvements while the Field Artillery Branch
deployed the systems and developed tactical doctrine.
