Following the initiation of Major Command-controlled (MAJCON) four-digit Table of Distribution (T/D) organizations in 1948, the major commands were briefly authorized to organize air divisions, provided they secured USAF approval. Two four-digit air divisions (4310th Air Division and 7217th Air Division) were subsequently organized.

Besides numbered Air Divisions, a Named Air Division was an organization within a large support command that was assigned a major or important segment of that command's mission--e.g., the Electronic Systems Division handled a large part of the Air Force Systems Command's work-load in electronic systems.

Because they were usually technical or highly specialized in nature, named divisions generally had a large number of personnel. One named division of an operational command was the USAF Southern Air Division which absorbed resources of the United States Air Forces Southern Command in 1976, and was part of Tactical Air Command. The Tactical Air Command (TAC) was a command of the United States Air Force charged with battlefield-level (tactical) air combat, including light bombardment, close air support of ground troops, interdiction of enemy forces, and air transport of ground troops. ...

Air Divisions were gradually phased out of the Air Force command structure after the end of the Vietnam War, although some existed into the 1990's.
