The 475th Air Base Wing is an inactive United States Air Force unit. Its last duty station was at Yokota Air Base, Japan, where it was inactivated on 1 April 1992. A non-flying wing, the wing's mission at Yokota was to perform host unit missions. The wing had no numbered flying squadrons, although it did operate a few T-39 Sabreliner aircraft and UH-1 Huey helicopters. It was absorbed by the 374th Airlift Wing under the "one base-one wing" organizational concept.
