Between 1909 -- when that the US military purchased its first aircraft -- and 1947, the U.S. Air Force did not exist as a separate and independent military service organization. It went through a series of designations: Aeronautical Section, Signal Corps (1909); Aviation Section, Signal Corps (1914); United States Army Air Service (1918); United States Army Air Corps (1926), and United States Army Air Forces (1941).

WWII illustrated the value of airpower, and the need to change the basic organization of the US Military Forces. The result was the creation of a single Department of Defense with a strong Joint Chiefs of Staff with Army, Navy, and Air Force chiefs. In 1947 President Truman signed the National Security Act which established this new defense organization, and along with it the creation of the US Air Force as an independent service, equal to the U.S. Army and U.S. Navy. 

The official Air Force birthday is Sept. 18, 1947.
