Who signed the National Security Act of 1947 that created the Department of the Air Force?

The National Security Act of 1947 was signed by Harry S. Truman, marking a significant moment in U.S. history. This act not only established the Department of the Air Force as a separate military branch but also reorganized the framework of U.S. national security and defense. Prior to this legislation, air power was primarily the domain of the Army; however, the growth of air warfare in World War II made it evident that an independent air force was necessary for national defense.

The act aimed to streamline and enhance the efficiency of military operations by creating a more unified and coordinated approach to defense, which included the establishment of the National Security Council and the Central Intelligence Agency as well. Truman’s leadership was crucial during a pivotal period post-World War II, where the United States was redefining its military and strategic posture in the emerging Cold War context.
