The mission of the US Department of the Air Force is to fly, fight, and win -- in air, space, and cyberspace. Along with the Army, Navy, and Marine Corps, the US Air Force is a major military branch of the US Department of Defense responsible for defending the US and its interests through aerial, space, and cyber warfare. The agency includes more than a dozen major commands, including the Air Force Reserve and Air National Guard. It also consists of field operating agencies and direct reporting units, which are typically assigned to specialized missions. Originally part of the US Army, the US Air Force was formed as a separate branch when president Harry S. Truman signed the National Security Act of 1947.
The agency is administered by a civilian secretary who is supervised by an Air Force chief of staff; both posts are president-appointed. The chief is the principal adviser to the secretary on all department activities, including administration, logistical support and maintenance, operations, research and development, training, and welfare of personnel. The Air Force chief is also one of the military advisers to the president, the National Security Council, and the DoD's secretary of defense.
One way government agencies improve their communication and cost savings structure is through the process of ongoing technological innovation. In 2013 the government announced that the Army, Air Force, and Defense Information Systems Agency would collectively be using the most up-to-date suite of Microsoft products. The agency plans for the software adoption to launch new levels of cross-agency information sharing and provide advanced business intelligence and reporting capabilities.
