United States Air Force
The U.S. War Department created the first antecedent of the U.S. Air Force, as a part of the U.S. Army, on 1 August 1907, which through a succession of changes of organization, titles, and missions advanced toward eventual independence 40 years later. In World War II, almost 68,000 U.S. airmen died helping to win the war, with only the infantry suffering more casualties. In practice, the U.S. Army Air Forces (USAAF) was virtually independent of the Army during World War II, and in virtually all ways functioned as an independent service branch, but airmen still pressed for formal independence. The National Security Act of 1947 was signed on 26 July 1947 by President Harry S Truman, which established the Department of the Air Force, but it was not until 18 September 1947, when the first secretary of the Air Force, W. Stuart Symington, was sworn into office that the Air Force was officially formed as an independent service branch.
Air Force Cross (United States)
Originally entitled the "Distinguished Service Cross (Air Force)", the Air Force Cross was first proposed in 1947 after the creation of the United States Air Force as a separate armed service. The medal was designed by Eleanor Cox, an employee of the Air Force, and was sculpted by Thomas Hudson Jones of the Institute of Heraldry. The Air Force Cross was established by Congress in Public Law 88-593 on July 6, 1960, amending Section 8742 of Title 10, U.S. Code to change the designation of "Distinguished Service Cross" to "Air Force Cross" in case of awards made under Air Force Authority.
