Strategic Air Command (SAC) was a major command in the U.S. Air Force and was operationally in charge of America's land-based bomber aircraft and land-based strategic nuclear ballistic missile arsenal from 1946-92. SAC also controlled the infrastructure essential to support strategic bomber and ICBM operations i.e. air refueling for bombers, strategic reconnaissance and command post aircraft, as well as fighter escorts; until 1957. Following the collapse of the Soviet Union, SAC was reorganized on 1 June 1992 to the Air Combat Command (ACC).
The Strategic Air and Space Museum focuses on United States Air Force military aircraft and nuclear missiles. It is located near Ashland, Nebraska and is regarded as having one of the top collections of strategic aircraft.
