About this Unit
The 6917th Security Squadron was a United States Air Force unit established during the Cold War, primarily tasked with signals intelligence (SIGINT) and electronic surveillance operations. Activated in the 1950s, the squadron was stationed at San Vito dei Normanni Air Station in Italy, where it played a crucial role in monitoring Soviet and Eastern Bloc communications throughout Europe and the Mediterranean region. The squadron operated advanced intercept and analysis equipment, supporting both national intelligence objectives and NATO missions. The 6917th Security Squadron was eventually inactivated in the early 1990s as the Cold War ended and U.S. military intelligence operations in Europe were reorganized.
