The 705th Aircraft Control and Warning Squadron (ACW) was a United States Air Force unit activated during the early years of the Cold War. Established in 1950, its primary mission was to provide radar surveillance and air defense for North America as part of the Air Defense Command. The squadron operated at several locations, including South Dakota, before being inactivated in 1963 as advances in radar technology and changes in defense strategy rendered some early warning units redundant. Throughout its service, the 705th ACW played a vital role in maintaining the integrity of U.S. airspace during a critical era of heightened international tension.
