What event marked the creation of the independent Air Force in 1947?

The creation of the independent Air Force in 1947 was marked by the National Security Act of 1947. This pivotal piece of legislation reorganized the United States military and established the structure for the United States Department of Defense. One of its significant outcomes was the separation of the United States Army Air Forces, which had previously been part of the Army, into its own distinct branch—the United States Air Force.

This change recognized the Air Force's growing importance in modern warfare and national defense strategies, particularly in light of technological advancements in aviation and the strategic role of air power in global conflicts. The National Security Act was crucial for establishing a unified military command structure and ensuring coordinated efforts across all branches, fundamentally shaping America's military framework in the years to come.
