The wing is one of two Air Force units that can trace its history to another country. The wing's 4th Operations Group had its origins as the Royal Air Force Eagle Squadrons (Nos. 71, 121 and 133 Squadrons). When the United States entered World War II, these units, and the American pilots in them, were transferred to the United States Army Air Forces VIII Fighter Command, forming the 4th Fighter Group on 12 September 1942.
