The Intermediate-Range Nuclear Forces Treaty (INF Treaty) was an arms control treaty between the United States and the Soviet Union (and its successor state, the Russian Federation). US President Ronald Reagan and Soviet General Secretary Mikhail Gorbachev signed the treaty on 8 December 1987. The US Senate approved the treaty on 27 May 1988, and Reagan and Gorbachev ratified it on 1 June 1988.
The INF Treaty banned all of the two nations' nuclear and conventional ground-launched ballistic missiles, cruise missiles, and missile launchers with ranges of 1,000–5,500 km (620–3,420 mi) ("intermediate-range") and 500–1,000 kilometers (310–620 mi) ("shorter-range"). The treaty did not apply to air- or sea-launched missiles.
