The wing was one of several occupation units in Japan, and was inactivated on 1 April 1949 at Ashiya Airfield due to budget reductions.

At Yokota, the wing inherited a huge support complex, with some 47 sub-locations in all parts of Japan, including operation of Yokota and Tachikawa Air Bases, Fuchu and Chitose Air Stations, and numerous housing complexes within the Tokyo area.

The 556th RS was a highly specialized unit, employing modified C-130B-II, EB-57E electronic counter measures (ECM) aircraft and on occasion TDY C-130A-II and EC-97G Stratotankers.

The 475th ABW was inactivated on 1 April 1992 as part of a consolidation effort, being replaced as host unit at Yokota by the 374th, which was redesignated 374th Airlift Wing same date.
