Eleventh Air Force
Six months after Eleventh Air Force had been redesignated in Alaska, another headquarters, also named Eleventh Air Force, was established on 13 May 1946 and activated at Olmsted Field, Pennsylvania, on 13 June 1946. This new organization was assigned to Air Defense Command.
Nineteenth Air Force
The Nineteenth Air Force was inactivated in July 1973, as part of the economies enacted after the end of the Vietnam War. On 4 August 1998, the Chief of Staff of the United States Air Force (CSAF), General Michael E. Ryan, and the Acting Secretary of the Air Force (SECAF), F. Whitten Peters, announced their plans to implement a major change in the structure of the Air Force. They proposed to divide the USAF’s combat strength and the elements directly supporting it into ten Aerospace Expeditionary Forces (AEFs). Although the EAF concept was a major step in recasting the operations, outlook, and culture of the USAF, it sprang from the performance of missions traditionally performed by the Air Force — the timely response of land-based air power to the needs of the nation.
