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

Most of these airfields were under the command of Third Air Force or the Army Air Forces Training Command (AAFTC) (A predecessor of the current-day United States Air Force Air Education and Training Command).

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.

* Greenville was designated as an "Air Base" by Air Training Command while operated as private contractor-operated training facilities in the 1950s.
