United States Air Force
The United States Air Force (USAF) is the aerial and space warfare service branch of the United States Armed Forces. It is one of the five branches of the United States Armed Forces, and one of the seven American uniformed services. Initially formed as a part of the United States Army on 1 August 1907, the USAF was established as a separate branch of the U.S. Armed Forces on 18 September 1947 with the passing of the National Security Act of 1947. It is the youngest branch of the U.S. Armed Forces, and the fourth in order of precedence. The USAF is the largest and most technologically advanced air force in the world. The Air Force articulates its core missions as air and space superiority, global integrated intelligence, surveillance, and reconnaissance, rapid global mobility, global strike, and command and control.
Michigan Air National Guard
Insofar as possible, units were allotted to Michigan communities that had previously sponsored National Guard units and where state-owned or leased armory facilities were available. Initial priority was given to the organization of the State Headquarters, the 46th Infantry Division, and Air National Guard units. On 29 September 1946, the first post-war units of the Michigan National Guard were activated. 18 September 1947, however, is considered the Michigan Air National Guard's official birth concurrent with the establishment of the United States Air Force as a separate branch of the United States military under the National Security Act.
