Mouwembleem 13th Air Force (Sleeve patch 13th Air Force)

Established on 14 December 1942 at Plaine Des Gaiacs Airfield, on New Caledonia, 13 AF was a United States Army Air Forces combat air force deployed to the Pacific Theaterof World War II. It engaged in operations primarily in the South Pacific, attacking enemy forces in the Solomon Islands, Gilbert and Marshall Islands campaigns; Mariana and Palau Islands campaigns and the Philippines campaign (1944–45).

Thirteenth Air Force began operations in November 1942 as an organization composed of many widely separated Seventh Air Force and independent units scattered in theSouth Central Pacific during the Solomon Islands campaign.

Initially charged with taking a defensive stand against advancing enemy forces, Thirteenth Air Force later took the offensive flying a variety of aircraft, including the B-17 Flying Fortress, B-24 Liberator, B-25 Mitchell, B-26 Marauder, P-38 Lightning, P-39 Airacobra, P-40 Warhawk, P-61 Black Widow, C-46 Commando, C-47 Skytrain, and L-5 Sentinel.

It was Thirteenth Air Force P-38Gs of the 339th Fighter Squadron of the 347th Fighter Group which, on 18 April 1943, flew the mission which resulted in the death of Japanese Admiral Isoroku Yamamoto.

From 1942–1945, Thirteenth Air Force staged out of tropical jungles on more than 40 remote islands including the Gilbert and Marshall Islands campaign; Mariana and Palau Islands campaignand the Philippines campaign (1944–45), thus earning the nickname, "The Jungle Air Force." The command's units participated in a total of five different operation areas and 13 campaigns.

Thirteenth Air Force along with Fifth Air Force in Australia and Seventh Air Force in Hawaii were assigned to the newly created United States Far East Air Forces (FEAF) on 3 August 1944. FEAF was subordinate to the U.S. Army Forces Far East and served as the headquarters of Allied Air Forces Southwest Pacific Area. By 1945, three numbered air forces—5th, 7th and 13th—were supporting operations in the Pacific. FEAF was the functional equivalent in the Pacific of the United States Strategic Air Forces (USSTAF) in the European Theater of Operations.

After hostilities ended in 1945, Thirteenth Air Force established its headquarters at Clark Field, Philippines, in January 1946. In May of that year, it moved to Fort William McKinley, Luzon. By August 1947, 13AF returned to Clark Field. In December 1948, the unit moved to Kadena, Okinawa, where it remained for only a few months before returning to Clark in May 1949.
