How many existing basic design types are there of the weapons the United States and the Soviet Union had an arms race over?
Nuclear arms race The nuclear arms race was a competition for supremacy in nuclear warfare between the United States, the Soviet Union, and their respective allies during the Cold War. During this period, in addition to the American and Soviet nuclear stockpiles, other countries developed nuclear weapons, though none engaged in warhead production on nearly the same scale as the two superpowers.
Intermediate-Range Nuclear Forces Treaty The Intermediate-Range Nuclear Forces Treaty (INF Treaty) is the abbreviated name of the Treaty Between the United States of America and the Union of Soviet Socialist Republics on the Elimination of Their Intermediate-Range and Shorter-Range Missiles, a 1987 agreement between the United States and the Soviet Union (and later its successor states, in particular the Russian Federation). Signed in Washington, D.C. by President Ronald Reagan and Soviet leader Mikhail Gorbachev on 8 December 1987, the treaty was ratified by the United States Senate on 27 May 1988 and came into force on 1 June 1988.
