The
United States Air Force
(
USAF) is the
aerial
warfare and
space warfare branch
of the
U.S. armed
forces and one of the
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. It is the most recent branch of the U.S. military to be
formed.
The USAF provides the critical capabilities of Global Vigilance,
Global Reach, and Global Power, with 5,573 manned aircraft in
service (3,990 USAF; 1,213
Air
National Guard; and 370
Air Force
Reserve); approximately 180
unmanned combat air vehicles,
2,130 air-launched
cruise missiles,
and 446
intercontinental ballistic
missiles. The USAF has 327,452 personnel on
active duty, 115,299 in the
Selected and Individual Ready
Reserves, and 106,700 in the
Air
National Guard as of September 2008. In addition, the USAF
employs 171,313 civilian personnel, and has 57,000 auxiliary
members in the
Civil Air
Patrol.
The
Department of the Air Force is headed by the civilian
Secretary of the Air
Force who oversees all administrative and policy affairs.
The
Department of the Air Force is a division of the Department of
Defense
, headed by the Secretary of
Defense. The highest ranking military officer in the
Department of the Air Force is the
Chief of Staff of
the Air Force.
Mission
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:
- 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".
Search and rescue
The National Search and Rescue Plan designates the
United States Coast Guard as the
federal agency responsible for
maritime search-and-rescue
(SAR) operations, and the USAF as responsible for aeronautical SAR
in the continental U.S. with the exception of Alaska. Both agencies
maintain
Joint Rescue
Coordination Centers to coordinate this effort. To help the
USAF with the vast amount of search and rescue operations, the USAF
tasks the
Civil Air Patrol -- the
official United States Air Force Auxilliary—in many inland search
and rescue missions.
Air sovereignty
The USAF, through the
Air National
Guard, is the lead agency to maintain control of America's
airspace.
On 30 July 2009, Lt. Gen. Harry Wyatt, director of the Air National
Guard said that "Technologies needed for the mission include an
active, electronically scanned array radar (which can be used to
detect small and stealthy air threats including cruise missiles),
infrared search and track systems and beyond-line-of-sight
communications".
On 14 September 2009, Gen. Norton A. Schwartz, chief of staff of
the USAF, said that he hopes "to bring a combination of F-22, F-35,
legacy aircraft, including upgraded F-15 and F-16 fighters, and
unmanned aircraft to the [air sovereignty alert] ASA
mission."
Even so, the USAF plans to retire up to 80% of their total force
air sovereignty mission aircraft, which would leave no viable
aircraft at 18 current air sovereignty sites after 2015. The GAO
found that 17 of the 20 commanders of the ASA units "stated that
the Air Force treats ASA operations as a temporary mission and has
not provided sufficient resources."
Irregular warfare
In response to the conflicts in which the United States has been
engaged since the end of the Cold War, on 1 August 2007, Air Force
Doctrine Document 2-3 was released showing how air power could be
used to support or defeat an insurgency.
In order to help support these missions the USAF is considering
outfitting a counter-insurgency wing with small cheap ground
support fighters that can also be used for training USAF and allied
pilots in addition to counterinsurgency operations.
Airlift
The USAF provides both strategic and tactical airlift in support of
wartime, peacetime, and humanitarian efforts of the Department of
Defense.
The GAO found that Air Force plans should cover strategic airlift,
but that it may fall short in providing tactical airlift in support
of the United States Army.
History
The Army created the first antecedent of the USAF in 1907, which
through a succession of changes of organization, titles, and
missions advanced toward eventual separation 40 years later. The
USAF became a separate military service on 18 September 1947, with
the implementation of the
National Security Act of 1947.
The Act
created the United States Department of
Defense
, which was composed of three subordinate
departments, namely the Department of the Army, the Department of
the Navy and a newly-created Department of the Air Force.
Prior to 1947, the responsibility for military aviation was shared
between the Army (for land-based operations), the Navy (for
sea-based operations from
aircraft
carriers and
amphibious
aircraft), and the Marine Corps (for close air support of infantry
operations).

Recent history
In 2007, the USAF undertook a reduction-in-force. Because of budget
constraints, the USAF planned to reduce the service's size from
360,000 active duty personnel to 316,000. The size of the
active-duty force in 2007 was roughly 64% of that of the USAF at
the end of the
Gulf War in 1991. However,
the reduction was ended at approximately 330,000 personnel in 2008
to meet mission requirements. These same constraints have seen a
sharp reduction in flight hours for crew training since 2005.
On 5 June 2008,
Secretary of
Defense Robert M. Gates, accepted the resignations of both the
Secretary of the Air
Force,
Michael W. Wynne, and the
Chief of Staff of
the United States Air Force, Gen.
T. Michael
Moseley. Gates in effect fired both men for "systemic issues
associated with declining Air Force nuclear mission focus and
performance". This followed an investigation into two embarrassing
incidents involving mishandling of
nuclear weapons, and were also the
culmination of disputes between the Air Force leadership and Gates.
To put more emphasis on nuclear assets, the USAF established the
nuclear-focused
Air
Force Global Strike Command on 24 October 2008.
On 26 June 2009, the USAF released a force structure plan that cuts
fighter aircraft and shifts resources to better support nuclear,
irregular and information warfare. On 23 July 2009, The USAF
released their Unmanned Aerial System Flight Plan, detailing UAV
plans through 2047. One third of the planes that the USAF plans to
buy in the future are to be unmanned.
Conflicts
The United States has been involved in many wars, conflicts, and
operations using military air operations. Air combat operations
before, and since the official conception of the USAF
include:
Humanitarian operations
The USAF has also taken part in numerous humanitarian operations.
Some of the more major ones include the following:
- Berlin Airlift ,
1948-1949
- Operation Safe Haven,
1956-1957
- Operations Babylift, New Life, Frequent Wind, and New Arrivals, 1975
- Operation Provide
Comfort, 1991
- Operation Sea Angel,
1991
- Operation Provide Hope,
1992-1993
- Operation Unified Assistance,
December 2004 -
April 2005

Organization
Administrative organization
The USAF
is one of three service departments
, and is managed by the civilian Department of the Air
Force. Guidance is provided by the
Secretary of the Air
Force (SECAF) and the Secretary's staff and advisors. The
military leadership is the
Air
Staff, led by the
Chief of
Staff.
USAF direct subordinate commands and units are the
Field
Operating Agency (FOA),
Direct
Reporting Unit (DRU), and the currently unused Separate
Operating Agency.
The
Major
Command (MAJCOM) is the superior hierarchical level of command.
Including the
Air Force
Reserve Command, as of 30 September 2006, USAF has nine major
commands. The
Numbered
Air Force (NAF) is a level of command directly under the
MAJCOM, followed by Operational Command
(now unused),
Air Division (also now
unused),
Wing,
Group,
Squadron, and
Flight.

The USAF, including its air reserve components, field a total of
302 flying squadrons.
Operational organization
The above organizational structure is responsible for the peacetime
organization, equipping, and training of aerospace units for
operational missions. When required to support operational
missions, the
National
Command Authority directs a Change in Operational Control
(CHOP) of these units from their peacetime alignment to a
Regional Combatant Commander (CCDR). In the case
of AFSPC, AFSOC, PACAF, and USAFE units, forces are normally
employed in-place under their existing CCDR. Likewise, AMC forces
operating in support roles retain their componency to
USTRANSCOM unless chopped to a Regional
CCDR.
Aerospace Expeditionary Task Force
"Chopped" units are referred to as
forces. The
top-level structure of these forces is the
Air and Space
Expeditionary Task Force (AETF). The AETF is the Air Force
presentation of forces to a CCDR for the employment of Air Power.
Each CCDR is supported by a standing Component Numbered Air Force
(C-NAF) to provide planning and execution of aerospace forces in
support of CCDR requirements. Each C-NAF consists of a Commander,
Air Force Forces (COMAFFOR) and AFFOR/A-staff, and an Air
Operations Center (AOC). As needed to support multiple Joint Force
Commanders (JFC) in the COCOM's Area of Responsibility (AOR), the
C-NAF may deploy Air Component Coordinate Elements (ACCE) to liaise
with the JFC. If the Air Force possesses the most strategic air
assets in a JFC's area of operations, the COMAFFOR will also serve
as the Joint Forces Air Component Commander (JFACC).
Commander, Air Force Forces
The Commander, Air Force Forces (COMAFFOR) is the senior USAF
officer responsible for the employment of air power in support of
JFC objectives. The COMAFFOR has a special staff and an A-Staff to
ensure assigned or attached forces are properly organized,
equipped, and trained to support the operational mission.
Air Operations Center
The
Air Operations Center
(AOC) is the JFACC's
Command and Control (C²)
center. This center is responsible for planning and executing air
power missions in support of JFC objectives.
Air Expeditionary Wings/Groups/Squadrons
The AETF generates air power to support COCOM objectives from
Air Expeditionary Wings (AEW)
or Air Expeditionary Groups (AEG). These units are responsible for
receiving combat forces from Air Force MAJCOMs, preparing these
forces for operational missions, launching and recovering these
forces, and eventually returning forces to the MAJCOMs. Theater Air
Control Systems control employment of forces during these
missions.
Personnel
The classification of any USAF job is the
Air Force Specialty Code (AFSC).
They range from flight combat operations such as a gunner, to
working in a dining facility to ensure that members are properly
fed. There are many different jobs in fields such as computer
specialties, mechanic specialties,
enlisted aircrew, communication
systems, avionics technicians, medical specialties, civil
engineering, public affairs, hospitality, law, drug counseling,
mail operations,
security
forces, and search and rescue specialties.
Perhaps the most dangerous USAF jobs are
Explosive Ordnance Disposal (EOD),
Combat rescue officer,
Pararescue,
Security Forces,
Combat Control,
Combat
Weather and
Tactical Air
Control Party, who deploy with
infantry
and
special operations units who
disarm bombs, rescue downed or isolated personnel, call in
air strikes and set up landing zones in forward
locations. Most of these are
enlisted
positions. Other jobs have seen increasing combat, including
engineers, vehicle operators, and OSI.
Nearly all enlisted jobs are "entry level," meaning that the USAF
provides all training. Some enlistees are able to choose a
particular job, or at least a field before actually joining, while
others are assigned an AFSC at Basic Military Training (BMT). After
BMT, new airmen attend a technical training school where they learn
their particular AFSC. Second Air Force, a part of Air Education
and Training Command, is responsible for nearly all technical
training.
Training programs vary in length; for example, 3M0X1 (Services) has
31 days of tech school training, while 3E8X1 (Explosive Ordnance
Disposal) is one year of training with a preliminary school and a
main school consisting of over 10 separate divisions, sometimes
taking students close to two years to complete.
USAF rank is divided between
enlisted
airmen, non-commissioned officers, and commissioned officers, and
ranges from the enlisted Airman Basic (E-1) to the commissioned
rank of
General (O-10). Enlisted promotions
are granted based on a combination of test scores, years of
experience, and selection board approval while officer promotions
are based on time-in-grade and a
promotion board. Promotions among enlisted
personnel and non-commissioned officers are generally designated by
increasing numbers of insignia chevrons. Commissioned officer rank
is designated by bars, oak leaves, a silver eagle, and anywhere
from one to five (only in war-time) stars.
Commissioned officers
The commissioned officer ranks of the USAF are divided into three
sections: company grade, field grade, and general officers. Company
grade officers are those officers in pay grades O-1 to O-3, while
field grade officers are those in pay grades O-4 to O-6, and
general officers are those in pay grades of O-7 and above.
Currently, promotion from Second Lieutenant to First Lieutenant is
virtually guaranteed after two years of satisfactory service. The
promotion from First Lieutenant to Captain is competitive after
successfully completing another two years of service. Promotion to
Major and above is through a board process.
An officer's record
is reviewed by a selection board at the Air Force Personnel Center
at Randolph Air
Force Base
in San Antonio, Texas. This process occurs
approximately between the seven- and ten-year mark, where a certain
percentage of Captains will be selected for Major. This process
will repeat at the 11-14 year mark for promotion to Lieutenant
Colonel, and then around the eighteen-year mark for promotion to
Colonel.
Enlisted airmen

USAF enlisted members in the
foreground
Enlisted members of the USAF have pay grades from E-1 (entry level)
to E-9 (senior enlisted). While all USAF military personnel are
referred to as
Airmen, the term also refers to the
pay grades of E-1 through E-4, which are
below the level of
non-commissioned officers (NCOs).
Above the pay grade of E-4 (i.e., pay grades E-5 through E-9) all
ranks fall into the category of NCO and are further subdivided into
NCOs (pay grades E-5 and E-6) and
Senior
NCOs (pay grades E-7 through E-9); the term
Junior
NCO is sometimes used to refer to staff sergeants and
technical sergeants (pay grades E-5 and E-6).
The USAF is the only of the five branches of the United States
military where NCO status is not achieved until an airman reaches
the pay grade of E-5. In all other branches, NCO status is
generally achieved at the pay grade of E-4 (e.g., a
Corporal in the
Army and
Marine Corps,
Petty Officer Third Class in the
Navy and
Coast Guard). However, E-4s in the
Army with the rank of
Specialist
are not considered NCOs. The Air Force mirrored the Army from 1976
to 1991 with an E-4 being either a Senior Airman wearing three
stripes without a star or a Sergeant (referred to as "Buck
Sergeant"), which was noted by the presence of the central star and
considered an NCO. Despite not being an NCO, a Senior Airman who
has completed
Airman Leadership
School can be a supervisor.
Uniforms
USAF personnel wear uniforms that are distinct from those of the
other branches of the United States armed forces.
The first USAF dress
uniform, in 1947, was dubbed and patented "Uxbridge
Blue" after "Uxbridge 1683 Blue", developed at the
former Bachman-Uxbridge Worsted Company. The
current Service Dress Uniform, which was adopted in 1993 and
standardized in 1995, consists of a three-button, pocketless coat,
similar to that of a men's "sport jacket" (with silver "U.S." pins
on the lapels), matching trousers, and either a service cap or
flight cap, all in Shade 1620, "Air Force Blue" (a darker
purplish-blue). This is worn with a light blue shirt (Shade 1550)
and Shade 1620 herringbone patterned necktie. Enlisted members wear
sleeve insignia on both the jacket and shirt, while officers wear
metal rank insignia pinned onto the coat, and Air Force Blue
slide-on epaulet loops on the shirt. USAF personnel assigned to
Base Honor Guard duties wear, for certain occasions, a modified
version of the standard service dress uniform, but with silver trim
on the sleeves and trousers, with the addition of a ceremonial belt
(if necessary), wheel cap with silver trim and Hap Arnold Device,
and a silver aiguillete placed on the left shoulder seam and all
devices and accouterment.
The current utility uniform is called the
Airman Battle Uniform (ABU). The
previous utility uniform called the
Battle Dress Uniform (BDU) is still
authorized for wear but is becoming less common. The ABU is
scheduled to completely replace the BDU by 1 October 2011 (Fiscal
Year 2012).
Awards and badges
In addition to basic uniform clothing,
various badges are
used by the USAF to indicate a job assignment or
qualification-level for a given assignment. Badges can also be used
as merit-based or service-based
awards.
Over time,
various badges
have been discontinued and are no longer distributed. Authorized
badges include the Shields of USAF Fire Protection, and Security
Forces, and the Missile badge, which is given after working on a
missile system for over a year.
Training
All
non-prior service enlisted Airmen must undergo basic military
training (BMT), which takes place at Lackland AFB, Texas
. All officers are commissioned through the
United States Air Force
Academy,
Officer Training
School,
Academy of
Military Science, or the
AFROTC
program.Civil Air Patrol Cadets that make it to Cadet 2nd Lt. may
join the USAF as an E-3(Airman First Class)
Air Force Fitness Test

USAF members training at Lackland
AFB
The US Air Force Fitness Test (AFFT) is designed to test the body
composition, muscular strength/endurance and cardiovascular
respiratory fitness of airmen in the USAF. As part of the
Fit
to Fight program, the USAF adopted a more stringent physical
fitness assessment; the new fitness program was established on 1
January 2004, and replaces the annual ergo-cycle test that the USAF
had used for several years. In the AFFT, airmen are given a score
based on performance consisting of four components: waist
circumference, the crunch, the push-up, and a run. Airmen can
potentially earn a score of 100; while a passing score is 75
points.
Equipment
Culture
The culture of the United States Air Force is primarily driven by
pilots and so the pilots of various aircraft types have driven its
priorities over the years. At first there was a focus on bombers,
followed by a focus on fighters.
In response to the
2007
United States Air Force nuclear weapons incident the leadership
of the USAF was changed, and for the first time a
Chief of Staff of
the United States Air Force was chosen who did not have a
background as a fighter or bomber pilot.
Daniel L. Magruder, Jr defines USAF culture as a combination of the
rigorous application of advanced technology, individualism and
progressive airpower theory. Major General
Charles J. Dunlap, Jr. adds that Air Force
culture includes an egalitarianism bred from officers as warriors
who work with small groups of enlisted airmen either as the service
crew or onboard crew of their aircraft.
The 21st Century saw another culture shock for the Air Force as
"Lone Wolf" pilots were reassigned as Unmanned Aerial System(UAS)
operators.
Slogans and creeds
The United States Air Force has had numerous recruiting slogans
including "No One Comes Close" and "Uno Ab Alto". For many years,
the U.S. Air Force used "Aim High" as its recruiting slogan; more
recently, they have used "Cross into the Blue", "We've been waiting
for you" and "Do Something Amazing", and the newest one, "Above
All". Each wing, group, or squadron usually has its own slogan(s).
Information and logos can usually be found on the wing, group, or
squadron websites.
The Airman's Creed is a statement
introduced in the spring of 2007 to summarize the culture of the
Air Force. The Air Force Core Values are: "Integrity First",
"Service Before Self", "Excellence In All We Do".
To help further knowledge of their mission and functions, the Air
Force has also produced videos, such as "Setting the Conditions for
Victory" and "How We Fight", to outline the Air Force role in the
war on terrorism and how the service succeeds in its domains of
air, space, and cyberspace. The Above All campaign continues to
support the message of "air, space and cyberspace" dominance.
