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.
Pacific Air Forces
Andersen AFB in Guam was reassigned from Strategic Air Command (SAC) to PACAF in 1989, and Eleventh Air Force became a part of the command in late 1990. In the late 1980s and early 1990s, civil unrest in the Philippines and negotiations with the extant government of the Republic of the Philippines for the lease of Clark Air Base, along with other U.S. military installations in the Philippines, had reached an impasse. However, following the volcanic eruption of Mount Pinatubo, the resultant damage to Clark AB, and with a post-Cold War desire by the U.S. Government to reduce defense spending, Clark AB was closed and Thirteenth Air Force relocated in 1991.
