About this Unit
The 6920th Electronic Security Group was a United States Air Force unit specializing in signals intelligence (SIGINT) and electronic surveillance. Activated in the early 1980s and stationed at Misawa Air Base, Japan, the group played a crucial role in monitoring and analyzing electronic communications in the Pacific theater during the Cold War. Its mission supported U.S. and allied operations by providing valuable intelligence on regional military activities. The unit was eventually redesignated as part of the Air Force's broader restructuring of its intelligence and security forces.
