SALT II

Part of a series on the
History of the Cold War

The Strategic Arms Limitation Treaty (SALT) were two rounds of bilateral conferences and corresponding international treaties involving the United States and the Soviet Union—the Cold War superpowers—on the issue of armament control. The two rounds of talks and agreements were SALT I and SALT II.

Negotiations commenced in Helsinki, Finland, in November 1969. SALT I led to the Anti-Ballistic Missile Treaty and an interim agreement between the two countries. Although SALT II resulted in an agreement in 1979, the United States Senate chose not to ratify the treaty in response to the Soviet war in Afghanistan, which took place later that year. The Soviet legislature also did not ratify it. The agreement expired on December 31, 1985 and was not renewed.

The treaties led to the STARTs, or Strategic Arms Reduction Treaties, which consisted of START I (a 1991 completed agreement between the United States and the Soviet Union) and START II (a 1993 agreement between the United States and Russia, which was never ratified by the United States), both of which proposed limits on multiple-warhead capacities and other restrictions on each side's number of nuclear weapons. A successor to START I, New START, was proposed and was eventually ratified in February 2011.

SALT I is the common name for the Strategic Arms Limitation Talks Agreement signed on May 26, 1972. SALT I froze the number of strategic ballistic missile launchers at existing levels and provided for the addition of new submarine-launched ballistic missile (SLBM) launchers only after the same number of older intercontinental ballistic missile (ICBM) and SLBM launchers had been dismantled. SALT I also limited land-based ICBMs that were in range from the northeastern border of the continental United States to the northwestern border of the continental USSR. In addition to that, SALT I limited the number of SLBM capable submarines that NATO and the United States could operate to 50 with a maximum of 800 SLBM launchers between them. If the United States or NATO were to increase that number, the USSR could respond with increasing their arsenal by the same amount.
