Original Items: Only One Set Available. The United States Army Air Service (USAAS) (also known as the "Air Service", "U.S. Air Service" and before its legislative establishment in 1920, the "Air Service, United States Army") was the aerial warfare service component of the United States Army between 1918 and 1926 and a forerunner of the United States Air Force. It was established as an independent but temporary branch of the U.S. War Department during World War I by two executive orders of President Woodrow Wilson: on May 24, 1918, replacing the Aviation Section, Signal Corps as the nation's air force; and March 19, 1919, establishing a military Director of Air Service to control all aviation activities. Its life was extended for another year in July 1919, during which time Congress passed the legislation necessary to make it a permanent establishment. The National Defense Act of 1920 assigned the Air Service the status of "combatant arm of the line" of the United States Army with a major general in command.

This is a lovely pair of American made USAAS “Wings and Prop” officer’s collar insignia. There are hallmarks present, but are double stamped and hard to read. The details on the wings and prop are incredible and still very prominent for being over 100 years old! The reverse of the wings have a straight hinged pin with flat wire catches. Both are undamaged and still function properly.

This is an incredible opportunity to add a pair of early US Army Air Service collar devices to your collections. Comes more than ready to display!

History of the United States Air Force
The United States Air Force became a separate military service on 18 September 1947 with the implementation of the National Security Act of 1947. The Act created the National Military Establishment, later renamed the United States Department of Defense, which was composed of four of the five branches, the Army, Marine Corps, Navy, and a newly created Air Force. Prior to 1947, the responsibility for military aviation was divided between the Army for land-based operations and the Navy and Marine Corps for sea-based operations from aircraft carriers and amphibious aircraft. The Army created the first antecedent of the Air Force on 1 August 1907, which through a succession of changes of organization, titles, and missions advanced toward eventual separation 40 years later. The predecessor organizations leading up to today's U.S. Air Force are:

Aeronautical Division, Signal Corps (1 August 1907 – 18 July 1914)
Aviation Section, Signal Corps (18 July 1914 – 20 May 1918)
Division of Military Aeronautics (20 May 1918 – 24 May 1918)
Air Service, U.S. Army (24 May 1918 – 2 July 1926)
U.S. Army Air Corps (2 July 1926 – 20 June 1941)*
U.S. Army Air Forces (20 June 1941 – 17 September 1947)**

* The Air Corps became a subordinate element of the Army Air Forces on 20 June 1941, and was abolished as an administrative organization on 9 March 1942. It continued to exist as a branch of the Army (similar to the infantry, quartermaster, or artillery) until reorganization provisions of the National Security Act of 1947 (61 Stat. 495), 26 July 1947.

**The Army Air Forces were abolished by Transfer Order 1, Office of the Secretary of Defense, 26 September 1947, implementing the same provisions. Transfer Order 1 was the first of 200 Army-Air Force transfer agreements drawn up in June and July 1947, and ordered the transfer of all military and civilian personnel of the Army Air Forces to the Department of the Air Force and the USAF. The final transfer order was signed 22 June 1949.
