About this Unit
The 6988th Radio Squadron, Mobile (RSM), was a United States Air Force signals intelligence unit activated in 1951 during the Korean War. Stationed primarily at Yokota Air Base in Japan, the unit’s mission was to provide critical communications intelligence (COMINT) support by intercepting, analyzing, and reporting enemy radio transmissions. The 6988 RSM played a significant role in supplying real-time intelligence to United Nations forces, contributing to air operations and strategic planning throughout the conflict. After the Korean War, the unit continued its intelligence-gathering mission in the region until it was eventually redesignated and integrated into the evolving Air Force Security Service structure.
