During World War II, the United States Army Air Forces engaged in combat against the Empire of Japan in the South Pacific Area. As defined by the War Department, this consisted of the Pacific Ocean areas which lay south of the Equator between longitude 159° East and 110° West. It included New Zealand, New Caledonia, New Hebrides, Fiji, and most of the Solomon Islands. In early 1942, the area was under the Seventh Air Force. By November, the Thirteenth Air Force, was formed to command and control AAF organizations in the southern areas of the widely separated Seventh Air Force and independent units scattered in the South Pacific Area during the Solomon Islands campaign. As the war progressed, Thirteenth Air Force units moved into the South West Pacific theatre and coordinated their activities with Fifth as part of the Far East Air Forces, a new formation.
