On September 18, 2016 we celebrate the 69th birthday of the United States Air Force
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 US Army and US Navy. The official birthday of the US Air Force is 18 September 1947.
