The United States Air Force (USAF) is a branch of the United States Armed Forces. Originally formed as part of the United States Army on August 1, 1907, the USAF was established as a separate branch of the US Armed Forces on September 18, 1947 with the passage of the National Security Act of 1947. The US Air Force articulates its core mission as air supremacy, integrated global intelligence, surveillance and reconnaissance, rapid global mobility, global attack, and command and control. The U.S. Air Force is a branch of military service within the Department of the Air Force, one of the three military departments of the Department of Defense. The Air Force through the Department of Air Force is headed by the Secretary of the Air Force, who reports to the Secretary of Defense and is appointed by the President with approval of the Senate. The highest military officer in the Air Force is the Air Force Chief of Staff, who exercises oversight of Air Force units and serves as one of the Joint Chiefs of Staff. As directed by the Secretary of Defense and Secretary of the Air Force, certain Air Force components are assigned to unified combatant command. Combatant commanders are delegated operational authority from the forces assigned to them, while the Air Force Secretary and Air Force Chief of Staff retain administrative authority over their members. Along with conducting independent air operations, the US Air Force provides air support for ground and sea forces and assistance in troop recovery on the ground. The Air Force operates more than 5,369 military aircraft and 406 ICBMs. The Air Force has a budget of $156.3 billion and is the second largest branch of service, with 329,614 active-duty personnel, 172,857 civilian personnel, 69,056 reserve pilots and 107,414 Air National Guard aviators. Not all warplanes in the United States are operated by the USAF. The Navy operates aircraft on its carriers. The US Marine Corps also operates warplanes and carriers. All branches of the US military operate helicopters.
