About United States Department of the Air Force

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 Secretary of Defense.


One way government agencies improve their communication and cost savings structure is through the process of ongoing technological innovation.

The 2016 budget is based on US defense strategy. It restores capacity to meet Combatant Commanders' most urgent requirements, sustains readiness gains, and invests in nuclear; space; cyber; command and control; and Intelligence, Surveillance, and Reconnaissance (ISR) capabilities.

That year the US Air Force unveiled the Nellis Solar Array II which combined with Solar Array I to make the installation's photovoltaic field the largest in the DOD. The energy generated between the two is enough to power 9,000 southern Nevada homes as well as approximately 42% of the kilowatts per hour needed to power the installation.
