13th FIS

The 13th Fighter-Interceptor Squadron (13th FIS) was an active unit of the United States Air Force, originally constituted during World War II. It was activated in 1941 and served in the Pacific Theater, flying missions in defense of the Hawaiian Islands and later participating in combat operations across the region. During the Cold War, the squadron was reactivated and assigned air defense missions, operating aircraft such as the F-86 Sabre and F-102 Delta Dagger to protect U.S. airspace. The 13th FIS was inactivated in 1968 as part of a broader realignment of Air Defense Command forces.
