Strategic Air Command (SAC) was both a Department of Defense Specified Command and a United States Air Force (USAF) Major Command (MAJCOM) responsible for Cold War command and control of two of the three components of the U.S. military's strategic nuclear strike forces, the so-called "Nuclear Triad," with SAC having control of land-based strategic bomber aircraft and intercontinental ballistic missiles (ICBMs).

SAC primarily consisted of the Second Air Force (2AF), Eighth Air Force (8AF) and the Fifteenth Air Force (15AF), while SAC headquarters (HQ SAC) included Directorates for Operations & Plans, Intelligence, Command & Control, Maintenance, Training, Communications, and Personnel. At a lower echelon, headquarters divisions included Aircraft Engineering, Missile Concept, and Strategic Communications.
