923rd AC&W

The 923rd Aircraft Control and Warning Squadron (AC&W) was a United States Air Force radar unit activated in the early 1950s during the Cold War. Tasked with providing air defense for North America, the squadron operated long-range radar systems to detect and track potential airborne threats, particularly Soviet bombers. Initially stationed at Grenier Air Force Base, New Hampshire, the unit later moved to Hopedale Air Station, Labrador, Canada, as part of the Pinetree Line, a network of early warning sites. The 923rd AC&W Squadron played a crucial role in continental air defense until it was inactivated in 1968 due to advances in radar technology and shifting defense strategies.
