689th A C & W Squadron

• Activated During the Cold War: The 689th Aircraft Control and Warning (AC&W) Squadron was activated on 1 December 1953, at a critical time during the Cold War when the United States was expanding its radar defense network against possible Soviet air attacks. • Located in Mount Hebo, Oregon: The squadron was stationed at Mount Hebo Air Force Station in Oregon, a strategic location chosen for its elevation and proximity to the Pacific coast, providing optimal radar coverage. • Primary Mission: The 689th AC&W Squadron's main mission was to detect and track unidentified aircraft, providing early warning to defend American airspace as part of the Air Defense Command. • Role in SAGE: In the late 1950s and early 1960s, the squadron was integrated into the Semi-Automatic Ground Environment (SAGE) system, a revolutionary computer network for air defense coordination. • Challenging Weather Conditions: Mount Hebo was notorious for extreme weather, including heavy snow, high winds, and ice storms, which posed constant challenges to both personnel and equipment. • Dome Collapse Incident: In January 1962, the giant radar dome at Mount Hebo collapsed during a fierce windstorm, becoming a famous example of the site's harsh conditions and necessitating a rapid rebuild. • Korean War Connection: Many of the original squadron members were veterans of the Korean War, bringing valuable experience in radar operations and air defense. • Community Relations: The squadron and its personnel had strong ties with local communities, participating in events and often providing emergency assistance during severe weather or forest fires. • Deactivation: The 689th AC&W Squadron was deactivated on 30 September 1970, as improvements in radar technology and changes in strategic defense needs reduced the demand for isolated radar stations. • Legacy: The former Mount Hebo Air Force Station site is now a popular destination for hikers and history enthusiasts, with remnants of the squadron's presence still visible on the mountain top.
