18th FIS

The 18th Fighter-Interceptor Squadron (18th FIS) was an active unit of the United States Air Force, first constituted during World War II in 1942. Initially activated as the 18th Pursuit Squadron, it served in the Aleutian Islands Campaign, flying P-40 Warhawks to defend Alaska from Japanese forces. After World War II, the squadron was reactivated during the Cold War and assigned to air defense missions in Alaska, operating aircraft such as the F-89 Scorpion and later the F-102 Delta Dagger. The 18th FIS was inactivated in 1969 as part of the restructuring of North American air defense forces.
