The 17th Air Division (17th AD) is an inactive United States Air Force unit. Its last assignment was with Pacific Air Forces, stationed at U-Tapao Royal Thai Navy Airfield, Thailand. It was inactivated on 1 January 1986

Activated as the 17th Bombardment Wing on 18 December 1940 and assigned to Southeast Air District as a bombardment training organization. Apparently never had sufficient personnel to carry out effectively its mission. Inactivated on 3 September 1941.

Reactivated as part of Second Air Force in June 1942 as the 17th Bombardment Training Wing. Was the primary training command organization for USAAF heavy bombardment (B-17 Flying Fortress, B-24 Liberator) heavy groups during World War II from June 1942 until May 1944. Initially, it controlled the third phase of training, in which each bombardment group split into tactical components and operated from squadron sized airfields under simulated combat conditions. Later, the 17th supervised the first and second phases of heavy bombardment group and crew training.

In 1943 assumed mission for training B-29 Superfortress Very Heavy bombardment groups prior to their deployment to Twentieth Air Force in the Pacific Theater until April 1946 when it ceased all activity. It also exercised limited supervision over the training of the XXI and XXII Bomber Commands during 1944.

Reactivated an intermediate command echelon of Strategic Air Command in 1959, it gained control of the 340th and the 305th Bombardment Wings at Bunker Hill AFB, Indiana, and the 4040th Air Base Squadron at Richard I. Bong AFB, Wisconsin in 1959. The two bombardment wings flew normal SAC alert patrols and participated in special exercises as required. However, the division lost its bombardment wings and gained missile wings in 1963 and assumed responsibility for Titan and Minuteman missiles in Missouri, Kansas, and later Arkansas. When joined by the 70th Bombardment Wing, on 1 July 1965 with B-52 and KC-135 aircraft, the division reverted to an earlier designation - 17th Strategic Aerospace Division. From 1965-1971, the division's subordinate units frequently deployed bomber and tanker resources. Arc Light operations in Southeast Asia, consisting of military operations against enemy forces in Vietnam, drew most of the deployments.

From 1 July 1975 – 1 January 1976 as part of Pacific Air Forces, it maintained an effective training program for United States Air Force tactical units in Thailand. Inactivated as part of the USAF phaseout of activities in Thailand after the end of the Vietnam War.
