The United States Air Force (USAF) was officially established on September 18, 1947, marking the birth of the world’s first independent air force. It emerged from the Army Air Forces during World War II, evolving to meet growing national security demands.

With the onset of the Cold War and rapid technological advancements in aviation, leaders recognized the need for a dedicated air service focused solely on aerial dominance.
