Formed in the United States during World War II to provide air defense and combat training for the personnel of newly formed units, the Fourth Air Force was assigned, in turn, to Continental Air Forces, Air Defense Command, and Continental Air Command before inactivating in 1960. The Fourth Air Force served in the air defense program, 1966-1969 and became part of the Reserve program in 1976.
The Indian AirForce (IAF) was established with the passing of the Indian AirForce act on October 8, 1932.
The Indian AirForce's Number 45 squadron quickly responded to the urgent call for air strikes against the Pakistani army and IAF Vampire FB Mk 52s were successful in staggering the Pakistani invasion.
During the Kargil War with Pakistan, the Indian AirForce is said to have proved the decisive force in accelerating the end of the conflict.
Renamed the U.S. Army AirForces (USAAF) on March 9, 1942, and considered a separate arm of the Army, the new USAAF had an equal "voice" with the Army and Navy.
Several of these airforces and divisions grew out of earlier Air Corps commands—for example, the Eighth AirForce was originally called VIII Bomber Command—as the service expanded in size and organization with multiple lower tiers added and yet higher echelons such as U.S. Strategic AirForces created to control the whole.
The airforces and divisions were divided into a total of 91 wings, called Bombardment, Tactical Reconnaissance, Training or Composite depending on whether their primary intended role was strategic bombing, pursuit, air support, et cetera.
