Happy 75th Birthday United States Air Force

Celebrate The Air Force’s Diamond Anniversary

Air Force Birthday

The U.S. Air Force was officially founded on 18 September 1947, and in the decades since it has established itself as an air force second-to-none.

Yet the Air Force’s history and heritage goes back the turn of the twentieth century.

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).
