74th FIS Thule, Greenland

The 74th Fighter-Interceptor Squadron (FIS) was a United States Air Force unit stationed at Thule Air Base, Greenland, during the early years of the Cold War. Reactivated at Thule in 1952, the squadron was tasked with providing air defense for the strategic Arctic outpost, operating aircraft such as the F-89 Scorpion to intercept potential Soviet bombers approaching North America over the polar route. The 74th FIS played a critical role in the North American Aerospace Defense Command (NORAD)'s early warning network, contributing to continental air security. The squadron remained at Thule until its inactivation in 1958, as advancements in missile technology shifted the focus of air defense strategies.
