Army Air Field (AAF) refers to a type of airfield or airport that was specifically designed and constructed for the use of the United States Army Air Forces (USAAF) during World War II.

Army Air Fields were typically built to support the training, operations, and maintenance of military aircraft, and were often located near military bases, training facilities, or other strategic locations. These airfields were equipped with runways, taxiways, hangars, and other infrastructure necessary to support military aviation operations.

During World War II, the USAAF constructed numerous Army Air Fields across the United States, as well as in other countries, to support the war effort. These airfields played a critical role in the training of pilots, aircrews, and ground personnel, as well as in the deployment and operation of military aircraft.

Many Army Air Fields were also used as bomber bases, fighter bases, or as staging areas for aircraft being deployed to combat theaters. Some notable examples of Army Air Fields include:

• March Army Air Field in California
• Luke Army Air Field in Arizona
• Moody Army Air Field in Georgia
• Selfridge Army Air Field in Michigan

After World War II, many Army Air Fields were decommissioned or converted to civilian use, and some were renamed or redesignated as Air Force bases or other types of military installations. Today, the term "Army Air Field" is largely a historical relic, and is no longer commonly used.
