The 326th Aeronautical Systems Wing is an inactive wing of the United States Air Force. It was last assigned to the Aeronautical Systems Center at Wright-Patterson Air Force Base, Ohio, where it was inactivated in 2008. The wing was first activated as the 326th Fighter Group in August 1942 during World War II and participated in the air defense of the Northeast until 1943, flying from Bradley Field, Connecticut. It moved to the Southeastern US where it was an operational and replacement training unit until it was disbanded in 1944 in a major reorganization of Army Air Forces units not programmed for overseas deployment. The group was reconstituted in 1955 as part of an Air Defense Command program to revive fighter units that had participated in World War II. The group provided air defense of the Northwestern United States until 1961 when it was replaced by the 57th Fighter Group, which assumed its personnel, equipment and mission. It was redesignated as the 326th Tactical Fighter Group in 1985 but remained inactive. In 2006, the group was consolidated with the Long Range Strike Systems Wing, which had been activated a year earlier at Wright-Patterson Air Force Base Ohio and the consolidated unit became the 326th Aeronautical Systems Wing. The wing conducted systems testing of advanced strike weapons for another two years before inactivating in 2008 when Air Force Materiel Command returned to its traditional directorate system of organization.
