About this Unit
The United States Air Force Security Service (USAFSS) was established in October 1948 as a dedicated signals intelligence (SIGINT) and cryptologic organization within the U.S. Air Force. Its primary mission was to intercept, analyze, and exploit foreign communications and radar signals during the Cold War, supporting both national and tactical intelligence needs. USAFSS operated globally, with listening posts and airborne platforms providing valuable intelligence during key conflicts, including the Korean and Vietnam Wars. In 1979, the unit was redesignated as the Electronic Security Command, marking a new era in Air Force intelligence operations.
