684th Radar Squadron

• Activation Date: The 684th Radar Squadron was originally activated on 1 February 1956, during the Cold War, as part of the United States' expanding air defense system. • Main Mission: Its primary role was to operate radar systems for the detection and tracking of aircraft, serving as a critical part of the Air Defense Command (ADC) network. • Location: The squadron was stationed at Mount Hebo Air Force Station, located near the Oregon coast, providing coverage for the northwestern United States. • SAGE System Integration: The 684th became part of the Semi-Automatic Ground Environment (SAGE) system, which used computers to coordinate radar data and direct interceptor aircraft. • Weather Challenges: Mount Hebo's location exposed the squadron to extreme weather, including heavy fog, rain, and strong winds, which frequently challenged operations and maintenance. • Radar Technology: The unit operated advanced long-range search radars such as the AN/FPS-24, AN/FPS-26A, and AN/FPS-90, representing the cutting edge of radar technology at the time. • Titan II Missile Accident: In 1968, a Titan II missile being transported near the station suffered an accident, highlighting the ever-present risks around military technology and operations. • Deactivation: The 684th Radar Squadron was inactivated on 30 September 1979, as changes in defense strategy and technology rendered many radar sites obsolete. • Legacy: The remains of Mount Hebo Air Force Station, where the squadron was based, are still visible today and serve as a historical site for military enthusiasts. • Unique Community: The isolated location led to a close-knit community among squadron personnel and their families, who often organized social events and supported each other through challenging conditions.
