6903rd Security Squadron

The 6903rd Security Squadron was a United States Air Force unit established during the Cold War era, primarily tasked with signals intelligence (SIGINT) and communications security missions. Activated in the 1950s, the squadron was stationed at Osan Air Base, South Korea, where it played a critical role in monitoring and intercepting communications from adversary nations in the region. The 6903rd supported United Nations Command and U.S. Forces Korea by providing timely intelligence vital for operational planning and regional security. In the early 1990s, as part of a broader restructuring of Air Force intelligence units, the 6903rd Security Squadron was redesignated and later integrated into the 303rd Intelligence Squadron, continuing its legacy of intelligence excellence.
