World War II had been over for two years and the Korean War lay three years ahead when the Air Force ended a 40-year association with the U.S. Army to become a separate service. The U.S. Air Force thus entered a new era in which airpower became firmly established as a major element of the nation's defense and one of its chief hopes for deterring war. The Department of the Air Force was created when President Harry S Truman signed the National Security Act of 1947.
Air Force Day is a celebration of airpower in the aftermath of World War Two. This observance is slightly complicated due to the nature of American air power at the time, but the designation of Air Force Day was an important step toward the recognition of United States air superiority in both Europe and Asia at the time.
Air Force Day was last observed on August 1, 1949. The Air Force Birthday is celebrated on September 18th each year.
It also likely brought the Department of Defense a step or two closer to establishing what we now know as the United States Air Force, thanks to the increased awareness of air power as an effective tool in modern warfare.
