U.S. Air Force Security Service

Overview
The U.S. Air Force Security Service (AFSS or USAFSS) was essentially the U.S. Air Force's cryptographic intelligence branch; its motto was Freedom through Vigilance. It was created in October 1948 and operated until 1979, when the branch was re-designated the "Electronic Security Command." It was later re-designated "Air Force Intelligence Command," "Air Intelligence Agency," and is currently called the Air Force Intelligence, Surveillance and Reconnaissance Agency.
