Electronic Security Command

The Electronic Security Command (ESC) was established by the United States Air Force on August 1, 1979, succeeding the former United States Air Force Security Service (USAFSS). ESC was responsible for signals intelligence (SIGINT), electronic warfare, and securing Air Force communications worldwide during the Cold War. The command played a critical role in monitoring adversary communications, providing intelligence support, and protecting U.S. and allied operations from electronic threats. In 1991, ESC merged with other organizations to form the Air Force Intelligence Command, later evolving into today’s Air Force Intelligence, Surveillance, and Reconnaissance Agency.
