11th Fighter-Interceptor Squadron

An 11th FS P-40 in Alaska, 1943

The squadron was activated as the 11th Pursuit Squadron at Selfridge Field, Michigan in January 1941 as one of the original squadrons of the 50th Pursuit Group. It trained with Vultee BT-13 Valiant and second-line Seversky P-35 Guardsman pursuit fighters at Selfridge.[2][3][4] In September, the squadron moved to Key Field, Mississippi, where it equipped with Curtiss P-40 Warhawks.[5]

Shortly after the Japanese attack on Pearl Harbor, the 11th was dispatched to Elmendorf Field to reinforce the defenses of Alaska against Japanese attack, departing on 19 December.[5] The urgency of the need for reinforcements in Alaska was so great that the squadron was picked even though its pilots were untrained on the flight conditions they could expect to experience in Alaska. Two weeks elapsed before the planes reached the Sacramento Air Depot for winterization, and at the end of the month when the 11th was officially located at Elmendorf, none of its planes had left McClellan Field. Bad weather delayed necessary test flights and caused the loss of some of the squadron's Warhawks. The first plane finally left California on 1 January 1942. The lack of adequate landing fields en route, poor communications, and pilot inexperience further delayed the squadron's movement. By 25 January only 13 of the 11th's twenty-five P-40s were at Elmendorf in flyable condition and six others had been lost during the movement.[2][6]

After the Japanese invasion of the Aleutians in June 1942, the squadron was engaged in combat operations 1942–1943, equipped with Warhawks and long-range Lockheed P-38 Lightnings for offensive operations against Japanese fortifications on Attu and Kiska; took part in the liberation of Attu, 1943. It remained in the Aleutian for the balance of the war, inactivating on Shemya in August 1946, when its personnel and equipment were transferred to the 64th Fighter Squadron.[2][7]

F-102 Delta Dagger 56-1500, 1958

Newly received F-106, 1960

It was reactivated in December 1952 as part of Air Defense Command, replacing the federalized 179th Fighter-Interceptor Squadron of the Minnesota Air National Guard 179th FIS flying F-51D Mustangs. In the fall of 1953 the unit transitioned into jet F-89D Scorpions and later the F-102 Delta Dagger. In June 1960 the 11th FIS transitioned into F-106 Delta Darts which it flew until September 1968 when it was inactivated. On 22 October 1962, before President John F. Kennedy told Americans that missiles were in place in Cuba, the squadron dispersed one third of its force, equipped with nuclear tipped missiles to Volk Field at the start of the Cuban Missile Crisis.[8][9] These planes returned to Duluth after the crisis.

Upon inactivation, the squadron's mission personnel, and F-106s were transferred to the 87th Fighter-Interceptor Squadron at Duluth IAP.
