United States Air Force (USAF) is the aerial warfare branch of the armed forces of the United States and one of the seven uniformed services of the United States. Initially born as the United States Army Air Corps, the USAF was formed as a separate branch of the military on September 18, 1947. It was the last branch of the U.S. military to be formed.

Its role is "To provide sovereign options for the defense of the United States and its global interests. To fly and fight in Air, Space, and Cyberspace"

Organisation

The USAF is part of the Department of the Air Force, which is in turn part of the Department of Defense. The civilian leader is the USAF is the Secretary of the Air Force, who reports to the Secretary of Defense. The military leader of the USAF is the Chief of Staff, United States Air Force, who is a member of the Joint Chiefs of Staff, and reports to the Secretary of the Air Force.

The USAF is organised into several Major Commands to carry out its various functions.

The USAF has the following major commands:

• Headquarters, United States Air Force
  • Tactical Air Command
    • First Air Force
    • Second Air Force
    • Fifth Air Force
    • Ninth Air Force
    • Twenty-First Air Force
  • Strategic Air Command
    • Eighth Air Force (Strategic Bombers)
    • Fifteenth Air Force (Reconnaissance)
    • Twentieth Air Force (ICBMs)
  • Military Airlift Command
    • Twelfth Air Force
    • Fourteenth Air Force
    • Eighteenth Air Force
  • Air Force Special Operations Command
    • Twenty-Third Air Force
  • Air Force Cyber Command
  • Air Force Space Command
  • Air Education & Training Command
    • Nineteenth Air Force
  • Air Force Material Command
  • Air Force Reserve Command
    • Fourth Air Force
    • Tenth Air Force
    • Twenty-Second Air Force
  • Pacific Air Forces
    • Fifth Air Force (Japan)
    • Seventh Air Force (Korea)
    • Eleventh Air Force (Alaska)
    • Thirteenth Air Force (Hawaii)
  • United States Air Forces in Europe
    • Third Air Force (Northern Europe, Western Europe)
    • Sixteenth (Southern Europe)
    • Seventeenth Air Force (South West Europe, North Africa)
  • Air National Guard
    • 50 States
    • 2 Territories
    • District of Columbia
  • Air Forces not attached to a USAF Major Command
    • Sixth Air Force (US Southern Command)
    • United States Central Command Air Forces (US Central Command)

The role of most of these operational commands is to sustain, and train forces, and to provide forces to the Unified Combatant Commands. Under each Major Command, there are Numbered Air Forces.

The Numbered Air Forces in the functional commands hold units for deployment for the regional commands. The Numbered Air Forces in the Regional Commands hold some, or all of the USAF units in that Command. These units are not permanently assigned, for example, the 48th Tactical Fighter Wing is under the command of the Third Air Force in USAFE, but it is under the permanent jurisdiction of Tactical Air Command's Fifth Air Force. Some Regional Major Commands have multiple numbered air forces. PACAF has four numbered air forces.

Only Commands with flying units have Numbered Air Forces. Air Force Space Command, for example has no air forces. Likewise, for Commands with flying and non-flying units, only flying units are included in Numbered Air Forces. Numbered Air Forces vary greatly in size.

Air Force Special Operations Command

Air Force Special Operations Command is composed of highly trained, rapidly deployable Airmen who are equipped with specialized aircraft. These forces conduct global special operations missions ranging from precision application of firepower, to infiltration, aviation foreign internal defense, exfiltration, resupply and refueling of SOF operational elements. The command's special tactics squadrons combine combat controllers, special operations weathermen, pararescuemen, and combat rescue officers to form versatile SOF teams. The command also possesses forces intended specifically for irregular warfare, or foreign internal defense. This force provides a more or less comprehensive counter-insurgency aviation capability as opposed to the large, dedicated light attack/COIN force in Tactical Air Command. In addition, the attack aircraft provide cover for Combat Search and Rescue missions, in the manner of the Douglas A-46 Skyraider in Vietnam. AFSOC's unique capabilities include airborne radio and television broadcast for psychological operations, as well as combat aviation advisors to provide other governments military expertise for their internal development.

Air Force Materiel Command conducts research, development, test and evaluation, and provides the acquisition management services and logistics support necessary to keep Air Force weapon systems ready for war. The command develops, acquires and sustains the aerospace power needed to defend the United States and its interests for today and tomorrow. This is accomplished through management, research, acquisition, development, testing and maintenance of existing and future weapons systems and their components.

Its main testing unit is the Air Force Flight Test Center. It consists of the 412th Test Wing, based at Edwards Air Force Base, California and a Base Wing to provide support.

AFMC operates examples of almost every aircraft used by the US Air Force. Aircraft operated permanently by AFMC are as follows:

• Northrop T-38 Talon
• Boeing C-135 Stratolifter (mostly MKC-135)
• Boeing C-137 Stratoliner
• North American T-39 Sabreliner

Aircraft currently being tested include:

Civil Reserve Air Fleet

The Civil Reserve Air Fleet is part of the United States's mobility resources. Selected aircraft from U.S. airlines, contractually committed to Civil Reserve Air Fleet, support United States Department of Defense airlift requirements in emergencies when the need for airlift exceeds the capability of military aircraft.

As of May 2007, 37 carriers and 1,364 aircraft were enrolled in the CRAF. This includes 1,273 aircraft in the international segment (990 in the long-range international section and 283 in the short-range international section), and 37 and 50 aircraft, respectively, in the national and aeromedical evacuation segments, and four aircraft in the Alaskan segment. These numbers are subject to change on a monthly basis.

Three stages of incremental activation allow for tailoring an airlift force suitable for the contingency at hand. Stage I is for minor regional crises, Stage II would be used for major theater war and Stage III for periods of national mobilization.

National Markings

These national markings are used by most US military aircraft, with the exception of United States Army aircraft which simply carry the words "UNITED STATES ARMY" in black lettering on the fuselage (fixed-wing aircraft) or the tail boom (helicopters).

Normal Marking

This is used by most non-tactical aircraft. Some USAF ground vehicles (notably non-tactical airfield firefighting vehicles, and special public relations vehicles) use this insignia.

Low Visibility (Grey)

Used by tactical aircraft with grey colour schemes.

Low Visibility (Black)

Used by tactical aircraft with grey, or green colour schemes. It is also used by USAF armoured cars, including the M113's used by some ground defence units, and the M48A5 and M60A3 Patton tanks in limited use with some EOD units and some ground defence units (referred to as "Protected Standoff Munitions Disruptors").

Two other monochrome roundels exist, white for SR-71, U-2, and F-117, and red for some SR-71 and U-2 aircraft.

Uniforms

Service Uniform

The USAF's service uniform has changed little since the foundation of the Air Force, being essentially a blue grey version of the Army uniform. This was chosed because the Air Force was formed out of the United States Army Air Force.

USAF Service Uniform

Airman Battle Uniform

The Airman Battle Uniform is the standard ground working dress of the USAF, and replaced BDU.

Flying Uniform

The standard working dress for aircrew is a nomex flying suit in either olive drab or tan.
