Mouwembleem 1st Air Force (Sleeve patch First Air Force)

One of the four original numbered air forces, First Air Force was activated as the Northeast Air District of the GHQ Air Force on 18 December 1940, at Mitchel Field, Long Island, New York. It was redesignated First Air Force on 9 April 1941 with a mission for the defense of the Northeast and Great Lakes regions of the United States.

World War II

During the initial months after the Pearl Harbor Attack, First Air Force organized what would eventually become the core of the Army Air Forces Antisubmarine Command (AAFSC), obtaining most of its forces from I Bomber Command to combat the German U-Boat threat along the Atlantic Coast. AAFSC would eventually expand that mission to the Gulf of Mexico and Caribbeanuntil the antisubmarine mission was taken over completely by the Navy in mid-1943.

Beginning in May 1942, the mission of First Air Force became operational training of units and crews, and the replacement training of individuals for bombardment, fighter, and reconnaissance operations. It received graduates of Army Air Forces Training Command flight schools; navigator training; flexible gunnery schools and various technical schools, organized them into newly activated combat groups and squadrons, and provided operational unit training (OTU) and replacement training (RTU) to prepare groups and replacements for deployment overseas to combat theaters. The First Air Force became predominantly a fighter OTU and RTU organization. Most P-47 Thunderbolt fighter groups were trained by I Fighter Command, along with P-39/P-63 Airacobra groups; C-47 Skytrain and later C-46 Commando groups by I Troop Carrier Command. By 1944, most of the Operational Training of groups ended, with the command concentrating on the training of individual replacements using Army Air Force Base Units (AAFBU) as training organizations at the airfields controlled by First Air Force.

Air Defense Wings were also organized for the major metropolitan areas along the northeast coast, using training units attached to the Wings. By 1944 the likelihood of an air attack along the eastern seaboard was remote, and these air defense wings were reduced to paper units.

By 1944, the vast majority of the USAAF was engaged in combat operations in various parts of the world, such as the Eighth Air Force in Europe and the Twentieth Air Force in the Pacific. The training units located within the United States (known as the Zone of the Interior, or "ZI".) under First, Second, Third and Fourth Air Force were all were placed under the unified command of the Continental Air Forces (CAF) on 13 December 1944, with the Numbered Air Forces becoming subordinate commands of CAF.
