Eleventh Air Force
Established on 28 December 1941 as the Alaskan Air Force at Elmendorf Field, Alaska Territory. 11 AF was a United States Army Air Forces combat air force in the American Theater of World War II, providing air defense of Alaska and engaging in combat operations primarily in the Aleutian Islands and Northern Pacific during the Aleutian Islands Campaign.
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.
