History World War II see 401st Fighter Squadron for full World War II history The 401st Fighter Squadron was established on 22 July 1943 at Westover Field, Massachusetts and equipped with P-47 Thunderbolts. Deployed to the European Theater of Operations (ETO) and assigned to Ninth Air Force in England, it engaged in combat operations until May 1945. It returned to the United States during September–November 1945, and was inactivated on 7 November 1945. Nebraska Air National Guard The unit was allotted to the National Guard on 24 May 1946 and redesignated the 173rd Fighter Squadron, and was further allotted to the Nebraska Air National Guard. It was organized and federally recognized as a P-51D Mustang squadron in July 1946. It was the second Air National Guard unit established, and assigned to the Iowa ANG 132d Fighter Group. It was posted to Lincoln Airport (later Lincoln Air Force Base), a former Second Air Force training field during World War II. With the long runways of the airport, the unit upgraded to Lockheed P-80A Shooting Star jet aircraft in early 1948. In 1950 the unit became the first Air National Guard organization to win the Winston P. Wilson Trophy as the outstanding jet fighter unit. It was the first of five Wilson trophies to be awarded to the Nebraska organization. Activated to federal service during the Korean War, the unit was sent to Dow AFB, Maine. Used by TAC to train replacement pilots in F-51D Mustang ground support operations, it also deployed unit members to Japan and Korea to fly combat missions. The 132d was moved to Alexandria AFB, Louisiana in May 1952 again with F-51s replacing the federalized Oklahoma ANG 137th Fighter-Bomber Wing which was deployed to France. The unit performed training as a tactical fighter unit until relieved from active service and returned to Nebraska ANG jurisdiction in January 1953. Upon returning to Lincoln, the squadron was forced to share facilities with the new Strategic Air Command provisional 4120th Air Base Group and extensive construction enlarging the airport to support SAC bombers as Lincoln Air Force Base. In late 1953, the unit re-equipped with more-advanced F-80C Shooting Star jets and the 173d
