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.
Thirteenth Air Force
On 6 October 2006, after a one-year transformation of command and control of air, space and information operations in the Pacific, Thirteenth Air Force officially began operations as a component numbered air force headquarters and welcomed a new commander. Former Pacific Air Forces Deputy Commander, Lt. Gen. Loyd S. "Chip" Utterback, assumed command of the unit 6 October, replacing Maj. Gen. Edward A. Rice, Jr., who had commanded Thirteenth Air Force from Andersen Air Force Base, Guam, and Hickam since January 2005. Previously designated as a management headquarters, Thirteenth Air Force became one of 10 organizations designed to enhance the operational level support, planning, command, control and execution of air, space and information operations capabilities across the full range of military operations throughout the U.S. Pacific Command's area of responsibility (minus the Korea theater of operations). In September 2012, 13 AF was inactivated and its functions merged into PACAF.
