About this Unit
The 4616th Air Defense Command (ADC) Squadron was a United States Air Force unit active during the early years of the Cold War. Established in the 1950s, it formed part of the Air Defense Command’s network tasked with continental airspace protection against potential Soviet bomber threats. The squadron operated radar sites, providing early warning and ground-controlled interception guidance to defending fighter aircraft. The 4616th ADC was eventually inactivated as changes in technology and strategy led to the consolidation and modernization of air defense assets.
