During World War II, the United States Army Air Forces (USAAF) established numerous air facilities in Louisiana for antisubmarine defense in the Gulf of Mexico and for training pilots and aircrews of USAAF fighters and bombers.

The larger facilities were Army Air Bases (AAB) while the Army Air Fields ( AAFld) were lesser facilities.

In addition, the Air Technical Service Command (ATSC) ran a significant number of airfields in a support role.

Many were converted into municipal airports, some were returned to agriculture and several were retained as United States Air Force installations and were front-line bases during the Cold War.

Hundreds of the temporary buildings that were used survive today, and are being used for other purposes.
