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.

Later in August 1943, it was decided to reassign Ninth Air Force to England to be the tactical air force in the planned invasion of France scheduled for May 1944. The IX Bomber Command reassigned its groups to Twelfth Air Force, and eventually its heavy bombardment groups became the core of the newly activated Fifteenth Air Force, while its B-25 Mitchell medium bomber groups remained with Twelfth Air Force.
