The youngest branch of the U.S. armed forces, the Air Force was originally developed as an aeronautical division of the Army Signal Corps in 1907. The following year the Army purchased its first plane, and in 1911 Congress appropriated funds for aviation. Control passed to the aviation division in 1914.
In 1926 Congress established the U.S. Army Air Corps, which was later renamed the Army Air Forces. During World War II air operations became increasingly independent of the Army. Some felt that to be most effective, air units needed to operate separately from ground units, allowing airpower to be concentrated where it was needed most. Finally on September 18, 1947, President Harry Truman signed the National Security Act that ended a 40-year association with the U.S. Army and created the U.S. Air Force.
With its headquarters in the Pentagon, the Department of the Air Force is organized in eight major commands throughout the world. In addition to carrying out fighting assignments, the Air Force provides airlift, refueling, reconnaissance, and other support to the Unified Combatant Commands.
Celebrating the establishment of the U.S. Air Force as a separate military unit, this stamp also honors the men and women who have protected our country and preserved our freedom.
