The Strategic Arms Limitation Treaty (SALT) refers to two arms control treaties—SALT I and SALT II—that were negotiated over ten years, from 1969 to 1979. The two treaties became the basis of all subsequent arms control agreements between the United States and the Soviet Union. SALT I was signed in 1972, and SALT II in 1979. The first one was ratified by both sides; the second one was observed without being ratified.
