We recognize the anniversary of the United States Air Force. On this date in 1947, the Air Force was officially established as a separate branch of the U.S. military, dedicated to protecting our nation through air and space power. We honor the service, sacrifice, and innovation of all Airmen—past and present—who continue to shape the future of national defense.
