The 689th Radar Squadron's long range radars were part of the Air Force
Semi-Automatic Ground Environment (SAGE) computer directed system for air defense. Available Squadron electronic equipment was able to support the detection, identification, and destruction of enemy aircraft. This was accomplished by communications between the SAGE computer atMcChord AFB , the radars and communications systems at Mt. Hebo, and airborne fighter-interceptor aircraft such as the supersonicF-106 Delta Dart jet.The 689th Radar Squadron was originally assigned to the SAGE Portland Air Defense Sector at
Adair Air Force Station , Oregon. Later it became part of the25th Air Division SAGE atMcChord AFB , Washington. Higher headquarters included4th Air Force (Hamilton AFB , California), andAir Defense Command (Peterson AFB , Colorado). Later in July 1967, Detachment 2 of the14th Missile Warning Squadron was activated at Mt Hebo AFS to operate a missile warning radar. [Strategic Communications: Alternative Approaches for Modernization. Congressional Budget Office. October 1981, Page 10 Table 1.] Both Squadrons are now deactivated. The Air Force equipment and facilities at Mt Hebo have been removed and the site returned to its natural state. A plaque is virtually all that remains of the radar station. It is dedicated "In Memory Of Those Who Served At Mt. Hebo AFS, Oregon. 689th Radar Sq., Oct.1956-June 1979. Det.2 14th MWS July 1967 - Sep.1980".References
