Air Force Technical Applications
The Air Force Technical Applications Center (AFTAC), the nation's sixth sense for decisive knowledge, provides national authorities quality technical measurements to monitor signatory countries compliance with the 1963 Limited Test Ban Treaty. AFTAC employs over 1,000 Department of Defense military and civilian personnel.
AFTAC operates and maintains a global network of nuclear event detection sensors called the U.S Atomic Energy System (USEDS). Once the USAEDS senses a disturbance underground, underwater, in the atmosphere or in space, the event is analyzed for nuclear identification and findings are reported to national command authorities through Headquarters U.S. Air Force.
