84 FIS CASTLE AFB

The **84th Fighter-Interceptor Squadron (84 FIS)** was an active unit of the United States Air Force, stationed at Castle Air Force Base (AFB), California, during the height of the Cold War. Originally activated in World War II, the squadron was reactivated at Castle AFB in 1955 as part of the nation’s air defense network, tasked with intercepting potential Soviet bomber threats over the western United States. While at Castle, the 84 FIS operated aircraft such as the Northrop F-89 Scorpion and later the Convair F-106 Delta Dart, reflecting advances in interceptor technology. The unit remained at Castle AFB until its inactivation in 1968, contributing significantly to continental air defense during a critical period of American military history.
