About this Unit
The 689th Aircraft Control and Warning (AC&W) Squadron was a unit of the United States Air Force activated during the early years of the Cold War. Established in 1953, the squadron was primarily tasked with radar surveillance and air defense operations, operating out of Mount Hebo Air Force Station in Oregon. Its mission was to detect, track, and identify potential airborne threats as part of the Air Defense Command's broader effort to safeguard North American airspace. The 689th AC&W Squadron played a critical role in early warning systems until it was inactivated in the late 1960s as newer technologies and organizational changes rendered many such squadrons obsolete.
