Activated in 1966, the squadron specialized in airborne signals intelligence (SIGINT) operations, particularly using EC-47 aircraft to intercept enemy communications in Southeast Asia. Personnel from the 6993rd provided critical real-time intelligence to U.S. and allied forces, significantly contributing to the effectiveness of air and ground operations during the conflict.
