4640th Support Squadron (ADC)

The 4640th Support Squadron (Air Defense Command) was a United States Air Force unit activated to provide specialized support services within the Air Defense Command (ADC) structure during the Cold War. Stationed at Hill Air Force Base, Utah, the squadron operated primarily in the late 1950s and early 1960s. Its primary mission included logistical, administrative, and operational support to ADC units responsible for continental air defense. The squadron was eventually discontinued as part of broader organizational changes within the Air Defense Command in the early 1960s.
