    The Department of Defense (DOD), with a single secretary, was created in 1947 under the National Security Act. It created three different departments [Dept. of the Army, Dept. of the Air Force, and Dept. of the Navy (which also commands the Marine Corps)].

    Prior to this, there were two departments with separate secretaries: Dept. of War and Dept. of Navy. The Air Force was known as the Army Air Corps. This is why 1947 is known as the Air Force's birthday.

    More can be learned if you Google: National Security Act, 1947. Also, read a little about it on Wikipedia.

    If you know someone in the Air Force (enlisted person), ask them if they will show you more about it in their PFE. They should know what that means.

    Hope this helps.

    The Department of Defense was not established by asking others to do your homework for you. It's called a book. Open one.
