The United States Air Force (
USAF) is the aerial warfare service branch of the
United States Armed Forces and one of the seven
American uniformed services. Initially part of the
United States Army, the USAF was formed as a separate branch of the military on
18 September 1947 under the
National Security Act of 1947.[5] It is the most recent branch of the
U.S. military to be formed, and is the largest and one of the world's most technologically advanced air forces. The USAF articulates its core functions as
Nuclear Deterrence Operations,
Special Operations, Air Superiority,
Global Integrated ISR,
Space Superiority,
Command and Control,
Cyberspace Superiority,
Personnel Recovery, Global
Precision Attack,
Building Partnerships,
Rapid Global
Mobility and
Agile Combat Support.[6]
The U.S. Air Force is a military service within the
Department of the Air Force, one of the three military departments of the
Department of Defense. The USAF is headed by the civilian
Secretary of the Air Force, who is appointed by the
President with the advice and consent of the
Senate. The highest-ranking military officer in the Department of the Air Force is the
Chief of Staff of the Air Force who exercises supervision over Air Force units, and serves as a member of the
Joint Chiefs of Staff. Air Force combat forces and mobility forces are assigned, as directed by the
Secretary of Defense, to the
Combatant Commanders, and neither the Secretary of the Air Force nor the Chief of Staff have operational command authority over them.
The U.S. Air Force provides air support for surface forces[7] and aids in the recovery of troops in the field.
As of 2012, the service operates more than 5,638 aircraft, 450
ICBMs and 63 satellites. It has a $
140 billion budget with 332,854 active duty personnel, 185,522 civilian personnel, 71,400
Air Force Reserve personnel, and 106,700
Air National Guard personnel.[2]
Mission, vision, and functions[edit]
Missions[edit]
According to the National Security Act of 1947 (61
Stat. 502), which created the USAF:
In general the
United States Air Force shall include aviation forces both combat and service not otherwise assigned. It shall be organized, trained, and equipped primarily for prompt and sustained offensive and defensive air operations.
The Air Force shall be responsible for the preparation of the air forces necessary for the effective prosecution of war except as otherwise assigned and, in accordance with integrated joint mobilization plans, for the expansion of the peacetime components of the Air Force to meet the needs of war.
§8062 of
Title 10
US Code defines the purpose of the USAF as:[8]
to preserve the
peace and security, and provide for the defense, of the
United States, the Territories, Commonwealths, and possessions, and any areas occupied by the United States;
to support national policy;
to implement national objectives;
to overcome any nations responsible for aggressive acts that imperil the peace and security of the United States.
The stated mission of the USAF today is to "fly, fight, and win in air, space, and cyberspace".[9]
Vision[edit]
"The United States Air Force will be a trusted and reliable joint partner with our sister services known for integrity in all of our activities, including supporting the joint mission first and foremost. We will provide compelling air, space, and cyber capabilities for use by the combatant commanders. We will excel as stewards of all Air Force resources in service to the
American people, while providing precise and reliable Global
Vigilance,
Reach and
Power for the nation".[9]
Core functions[edit]
Recently, the Air Force refined its understanding of the core duties and responsibilities it performs as a
Military Service Branch, streamlining what previously were six distinctive capabilities and seventeen operational functions into twelve core functions to be used across the doctrine, organization, training, equipment, leadership, and education, personnel, and facilities spectrum. These core functions express the ways in which the Air Force is particularly and appropriately suited to contribute to national security, but they do not necessarily express every aspect of what the Air Force contributes to the nation. It should be emphasized that the core functions, by themselves, are not doctrinal constructs.[10]
Air Superiority
Air Superiority is "that degree of dominance in the air battle of one force over another which permits the conduct of operations by the former and its related land, sea, air, and special operations forces at a given time and place without prohibitive interference by the opposing force" (JP 1-02).[10]
