 Kenney deviated from the normal structure of an air force by creating the Advanced Echelon ( ADVON ) under Whitehead . The new headquarters had the authority to alter the assignments of aircraft in the forward area , where fast @-@ changing weather and enemy action could invalidate orders drawn up in Australia . He created the 1st , 2nd and 3rd Air Task Forces to control air operations in a forward area for a specific mission , another departure from doctrine . While Kenney was enthusiastic about this innovation , Washington did not like it and , over Kenney 's objections , converted the three air task forces into the 308th , 309th and 310th Bombardment Wings . In June 1944 , Major General St. Clair Streett 's Thirteenth Air Force was added to the Allied Air Forces . Kenney created the Far East Air Forces ( FEAF ) from his Fifth Air Force headquarters , while ADVON became the Fifth Air Force under Whitehead . The RAAF formed the Australian First Tactical Air Force under Air Commodore Harry Cobby in October 1944 , and when MacArthur became commander of all Army forces in the Pacific , the Seventh Air Force was added as well . Major General Paul Wurtsmith replaced Streett in March 1945 , and Air Commodore Frederick Scherger replaced Cobby in May . Allied Air Forces was abolished on 2 September 1945 .
