By the end of World War II, the USAAF was divided into sixteen numbered Air Forces (First-Fifteenth and the Twentieth) distributed across all theaters of war, plus the Zone of the Interior (The USA, or more fondly, "home”) general air force stationed in the continental United States. To these were attached an additional eight Air Divisions which were sometimes detached and served as independent units when the need arose. These Air Forces and Divisions grew out of earlier Air Corps commands; for example, the Eigth Air Force was originally called VIII Bomber Command. Several Air Forces were created de novo as the service expanded during the war. The Air Forces and Divisions were divided into a total of 91 Wings, called Bombardment, Tactical Reconnaisance, Training or Composite depending on whether their primary intended role was strategic bombing, pursuit, air support etc.. The Air Forces also had jurisdiction over a number of logistical units like the Air Transport Command, successor to the pre-war Air Corps Ferrying Command.

Second Air Division
The Second Air Division evolved out of the reorganization of the VIII Bomber Command into the Eighth Air Force. Starting as the Second Bomb Wing, it became the Second Bomb Division and when the fighter wing was assigned, in January 1945, it was redesignated the Second Air Division.
While administrative responsibilities of bomb groups were retained by division headquarters, their operational functions were assigned to the 2nd, 14th, 20th and 96th Combat Bomb Wings, and, for a time, the 95th Combat Wing.
The 65th Fighter Wing maintained both an operational and administrative control and responsibility over its five fighter groups.
The Second Air Division's first bombing mission was flown on November 7, 1942; the last on April 25, 1945. A total of 95,948 sorties were flown in 439 operational missions by the division's B-24's, which dropped a total of 199,983 tons of bombs. Bomber crews accounted for 1,079 German aircraft destroyed in the air, and P-47's and P-51's of the fighter wing destroyed another 3,670 enemy aircraft in the air and on the ground. A total of 1,458 bombers and 649 fighters were lost in operations against the enemy.
