The United States Air Force is a military service branch organized 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 the Air Force is headed by the civilian Secretary of the Air Force, who reports to the Secretary of Defense and is appointed by the President with Senate confirmation. The highest-ranking military officer in the Air Force is the Chief of Staff of the Air Force, who exercises supervision over 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 commands.

As of 2017, the service operates more than 5,369 military aircraft[12] and 406 ICBMs.[13] The world's largest air force, it has a $156.3 billion budget[14] and is the second largest service branch of the U.S. Armed Forces, with 329,614 active duty airmen,[15] 172,857 civilian personnel,[16] 69,056 reserve airmen,[17] and 107,414 Air National Guard airmen.[18]
