Originally created on August 1, 1907 as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947.

- United States Air Force

The act merged the Department of the Army (renamed from the Department of War), the Department of the Navy, and the newly established Department of the Air Force (DAF) into the National Military Establishment (NME).

- National Security Act of 1947

The act also created the position of the secretary of defense as the head of the NME It established the United States Air Force under the DAF, which worked to separate the Army Air Forces into its own service.

- National Security Act of 1947

The United States Air Force is a military service branch organized within the Department of the Air Force, one of the three military departments of the Department of Defense.

- United States Air Force

On 26 July 1947, Truman signed the National Security Act of 1947, which set up a unified military command known as the "National Military Establishment", as well as creating the Central Intelligence Agency, the National Security Council, National Security Resources Board, United States Air Force (formerly the Army Air Forces) and the Joint Chiefs of Staff.

Department of Defense organizational chart (December 2013)

The United States secretary of defense (SecDef) is the head of the United States Department of Defense, the executive department of the U.S. Armed Forces, and is a high ranking member of the federal cabinet.

Subject only to the orders of the president, the secretary of defense is in the chain of command and exercises command and control, for both operational and administrative purposes, over all service branches administered by the Department of Defense – the Army, Marine Corps, Navy, Air Force, and Space Force – as well as the Coast Guard when its command and control is transferred to the Department of Defense.

The resulting National Security Act of 1947 was largely a compromise between these divergent viewpoints.

Drawing on hastily assembled Congressional support, and with the assistance of the so-called "Revolt of the Admirals", the Marine Corps rebuffed such efforts to dismantle the Corps, resulting in statutory protection of the Marine Corps in the National Security Act of 1947.

It was created on 20 June 1941 as successor to the previous United States Army Air Corps and is the direct predecessor of the United States Air Force, today one of the six armed forces of the United States.

Although other nations already had separate air forces independent of their army or navy (such as the British Royal Air Force and the German Luftwaffe), the AAF remained a part of the Army until a defense reorganization in the post-war period resulted in the passage by the United States Congress of the National Security Act of 1947 with the creation of an independent United States Air Force in September 1947.

As all 48 states then part of the Union were contained within the contiguous United States, the term "Zone of the Interior" for the First through Fourth Air Forces' areas of assignment was the Second World War's term for what is called "CONUS" by today's United States Department of Defense in the 21st century.

Truman's press secretary was his old friend Charles Griffith Ross. He had great integrity but, says Alonzo L. Hamby, as a senior White House aide he was, "A better newsman than news handler, he never established a policy of coordinating news releases throughout the executive branch, frequently bumbled details, never developed ... a strategy for marketing the president's image and failed to establish a strong press office."
