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

Most of these airfields were under the command of Second Air Force or the Army Air Forces Training Command (AAFTC).

In addition to AAF airfields, Dugway Army Air Field was established at Dugway Proving Ground, which had been established by the Chemical Warfare Service to test chemical attacks and defences.

Many of the airfields 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.
