866th radar Squadron

The 866th Radar Squadron was an Air Force unit activated during the Cold War era as part of the United States’ continental air defense network. Established in 1955, the squadron was stationed at Langdon Air Force Station in North Dakota, where it operated radar systems to detect and track potential airborne threats. Its primary mission was to provide early warning and ground-controlled interception guidance to defend North American airspace from Soviet bombers. The 866th Radar Squadron remained operational until its inactivation in 1979, following advancements in radar technology and changes in national defense priorities.
