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.
Twelfth Air Force
Since World War II, Twelfth Air Force has subsequently served both in Europe and later the United States. The Twelfth Air Force serves as the Air Force component to the United States Southern Command.The origins of Twelfth Air Force are traced back to a series of mid-1942 Allied planners' meetings to develop a strategy for the North African invasion or "Operation TORCH". Because this extensive operation required a new organization to provide enough manpower and equipment, activation plans were prepared simultaneously with the invasion strategy.
