Air superiority
Controlling the air so that friendly forces can operate and enemy forces cannot — the mission that makes every other joint operation possible, and the one the F-22 and now the F-47 exist to hold.
End strengths are FY2026 authorized (Public Law 119-60). Aircraft inventory as of September 30, 2025.
The United States Air Force is the air warfare service branch of the U.S. Armed Forces, established as an independent service on September 18, 1947 by the National Security Act. Its lineage runs back forty years further, to the Aeronautical Division of the Army Signal Corps founded on August 1, 1907 — a unit that began with one officer, two enlisted men and no aircraft.
The Air Force organizes around five core missions: air superiority, global strike, rapid global mobility, intelligence, surveillance and reconnaissance, and command and control. Between them they describe a service whose product is not territory but access — the ability to reach any point on earth quickly, see it, hold it at risk, and move forces and supplies to it.
Two of those missions are effectively unique. The Air Force operates two legs of the nuclear triad: the land-based intercontinental ballistic missile force and the bomber force, both under Air Force Global Strike Command. And Air Mobility Command’s tanker and airlift fleet is the reason any American military operation can happen far from home — every other service depends on it to deploy.
Like the Army, the Air Force fights as a Total Force. The Air National Guard and Air Force Reserve together account for roughly a third of the service’s people and a substantial share of its combat aircraft, tankers and airlifters. Many Guard units fly the same aircraft as their active-duty counterparts and deploy alongside them, a level of integration no other pairing of components matches.
The Air Force describes its purpose in five core missions. Everything the service buys and every way it organizes traces back to one of them.
Controlling the air so that friendly forces can operate and enemy forces cannot — the mission that makes every other joint operation possible, and the one the F-22 and now the F-47 exist to hold.
Holding any target on earth at risk, conventionally or with nuclear weapons, from bombers and intercontinental ballistic missiles kept on continuous alert.
Airlift and aerial refueling that move troops, equipment and humanitarian relief anywhere in days — the capability every other service depends on to deploy at all.
Manned, unmanned and space-derived collection that gives commanders the picture they act on, from theater-wide awareness down to a single vehicle.
The networks, airborne battle-management aircraft and operations centers that turn all of the above into coordinated action across a theater.
Two of the three legs of the nuclear triad — the Minuteman III missile force and the bomber fleet — held at readiness under Air Force Global Strike Command.
The Air Force is built from major commands that either generate forces or provide them to a combatant commander, beneath which sit numbered air forces, wings, groups and squadrons.
Organizes, trains and equips combat air, cyber and electromagnetic spectrum forces — roughly 155,000 people and 1,600 aircraft.
All intercontinental ballistic missiles and bombers — two legs of the nuclear triad.
Airlift, aerial refueling and aeromedical evacuation; about 107,000 Airmen and 1,100 aircraft.
Research, test, acquisition and lifecycle sustainment, with roughly 89,000 employees.
Recruiting, training and education — more than 293,000 students a year.
The air components to Indo-Pacific Command and to European and Africa Commands.
Air Force units nest from the major command down to the flight. Unlike Army echelons, they are defined by function rather than headcount.
| Major command | Tens of thousands of Airmen | General |
|---|---|---|
| Numbered air force | Operational tier within a MAJCOM | Major general |
| Wing | Typically about four groups | Colonel or brigadier general |
| Group | Several squadrons of one function | Colonel |
| Squadron | 7 to 600+ Airmen | Lieutenant colonel or major |
| Flight | The smallest standard unit | Captain or lieutenant |
The Air Force spent forty years inside the Army arguing that airpower was a strategic instrument rather than an auxiliary of ground forces. Independence in 1947 settled the argument institutionally; the Cold War settled it in practice.
Army aviation began on August 1, 1907 with the Aeronautical Division of the Signal Corps. Congress gave it statutory footing as the Aviation Section in 1914, separated it from the Signal Corps as the Army Air Service in 1918, renamed it the Army Air Corps in 1926, and consolidated it as the Army Air Forces in June 1941. Each change reflected the same unresolved question: whether air units supported ground campaigns or conducted campaigns of their own.
The Second World War answered it at scale. The Army Air Forces grew to roughly 2.4 million personnel and conducted strategic bombing campaigns over Europe and the Pacific that were, whatever their contested effectiveness, plainly independent operations. The National Security Act of 1947 created the United States Air Force as a separate service on September 18 of that year, with Stuart Symington as first Secretary and Carl Spaatz as first Chief of Staff. Weeks later, on October 14, Captain Chuck Yeager flew the Bell X-1 past Mach 1.
The new service was immediately tested. The Berlin Airlift, flown from June 1948 to September 1949, sustained a city of two million entirely by air and demonstrated that airpower could achieve a strategic result without combat. Strategic Air Command then anchored American nuclear deterrence for four decades, peaking in 1983 with 1,000 Minuteman missiles and 316 B-52s. In January 1991 the opening night of Desert Storm — F-117 stealth fighters over Baghdad — established precision air attack as the defining form of modern conventional warfare.
The Air Force gave up its space mission in 2019 when the Space Force was established, reintroduced warrant officers in 2024 for the first time since 1980, and is now rebuilding its bomber, missile and fighter fleets simultaneously for a potential peer conflict in the Pacific.
The U.S. Army Signal Corps establishes an Aeronautical Division — one officer, two enlisted men, and no aircraft yet.
Congress gives Army aviation statutory footing as the Aviation Section of the Signal Corps.
Army flying is separated from the Signal Corps and becomes a service in its own right.
The Air Corps Act renames and expands the organization, reflecting aviation’s growing independence.
The air arm is consolidated under one command ahead of American entry into the Second World War.
Army Air Forces campaigns over Europe and the Pacific grow the service to roughly 2.4 million personnel.
The National Security Act creates the United States Air Force, with Stuart Symington as Secretary and Carl Spaatz as Chief of Staff.
Captain Chuck Yeager flies the Bell X-1 to Mach 1.06 over the Mojave Desert.
Operation Vittles sustains West Berlin entirely by air for fifteen months after the Soviet blockade.
SAC anchors Cold War nuclear deterrence, peaking in 1983 with 1,000 Minuteman missiles and 316 B-52s.
The largest air campaign since the Second World War opens with F-117 stealth fighters over Baghdad, winning air superiority in hours.
The space mission transfers to the new Space Force, warrant officers return after four decades, and the B-21, Sentinel and F-47 recapitalize the fleet.
The Air Force is recapitalizing its bomber, missile and fighter forces simultaneously for the first time since the 1950s, while reorganizing how it presents forces to combatant commanders. A 2024 restructuring was substantially reversed in late 2025; a new Air Expeditionary Wing model takes effect from FY2027.
The stealth bomber replacing the B-1 and B-2. A second test aircraft flew in 2025 and production is accelerating toward roughly seven a year.
The replacement for the Minuteman III intercontinental ballistic missile force — the largest and most troubled modernization program, restructured after a 2024 cost breach.
The Next Generation Air Dominance fighter, awarded to Boeing, with 185 planned to replace the F-22 and a first flight targeted for 2028.
Uncrewed fighters designed to fly with piloted aircraft. The FQ-42A and FQ-44A were both selected for production in 2026, with 150 aircraft planned by 2030.
The tanker replacing the KC-135, with deliveries resumed after structural fixes — the least glamorous and most consequential program in the fleet.
Airborne battle management to replace the E-3 Sentry. Proposed for cancellation in 2025, it was preserved by Congress and put back on contract in 2026.
Air Force enlisted ranks are Airmen and then Sergeants, with the top three grades forming the senior noncommissioned officer tier. Officer titles are identical to the Army and Marine Corps. The service went without warrant officers from 1980 until 2024, when the grade returned for cyber and information technology specialists.
Warrant officers returned to the Air Force in 2024 for cyber and IT specialties; the first class graduated that December. First Sergeant is a duty position held at E-7 through E-9, marked by a diamond above the chevrons. Devices shown are schematic diagrams of each pay-grade tier, not reproductions of official insignia artwork.
Air Force heraldry is the youngest in the U.S. military and, appropriately, the most deliberately designed — most of it dates from a single burst of work between 1947 and 1951.
Ultramarine blue and Air Force yellow, sometimes called golden yellow. The pairing carries through the flag, the service dress uniform and Air Force heraldry generally.
Adopted March 26, 1951 by President Truman. An ultramarine blue field bearing the Air Force coat of arms and crest — a bald eagle, clouds representing a new firmament, and a wreath of six alternating folds of silver and blue — with thirteen white stars for the original colonies, grouped to also represent the three military departments.
Integrity First, Service Before Self, and Excellence In All We Do. They are taught from the first day of basic training and cited throughout an Airman’s career.
Written in 1939 by Robert MacArthur Crawford, who won a $1,000 magazine contest with it. First performed publicly at the 1939 National Air Races as The Army Air Corps, it was retitled on independence in 1947 and is universally known by its opening line, “Off we go into the wild blue yonder.”
Introduced in 2007 to give the service a single statement of professional identity, beginning “I am an American Airman. I am a warrior. I have answered my nation’s call.”
The dining-in and dining-out, the Order of the Sword, coining, and the Air Force Ball each September mark the service calendar — most of them adapted from older British and Army practice rather than invented in 1947.
September 18, 1947, when the National Security Act created it as an independent service. Its lineage runs back to August 1, 1907 and the Aeronautical Division of the Army Signal Corps, through the Army Air Service, Army Air Corps and Army Air Forces.
For fiscal year 2026 Congress authorized 321,500 active-duty Airmen, 106,300 in the Air National Guard and 67,500 in the Air Force Reserve, supported by roughly 183,000 Department of the Air Force civilians — a Total Force of more than 678,000.
4,865 as of September 30, 2025, across the active force, Air National Guard and Air Force Reserve. The largest categories are fighter and attack aircraft at 1,978, trainers at 981, transports at 633 and tankers at 510.
Air superiority; global strike; rapid global mobility; intelligence, surveillance and reconnaissance; and command and control. The Air Force also holds two of the three legs of the nuclear triad — the intercontinental ballistic missile force and the bomber force.
Enlisted ranks run Airman Basic, Airman, Airman First Class, Senior Airman, Staff Sergeant, Technical Sergeant, Master Sergeant, Senior Master Sergeant and Chief Master Sergeant. Officers run Second Lieutenant, First Lieutenant, Captain, Major, Lieutenant Colonel, Colonel, then Brigadier General through General.
Yes, again. The Air Force stopped appointing warrant officers in the 1950s and the last one retired in 1980. The grade was reintroduced in 2024 for cyber and information technology specialists, and the first class graduated that December.
Ultramarine blue and Air Force yellow. Both appear on the service flag, which was adopted in March 1951 and carries thirteen white stars for the original colonies.
Both are services within the Department of the Air Force, sharing a secretary. The Air Force operates aircraft and holds the air superiority, airlift and bomber and missile missions; the Space Force operates satellites, launch and space domain awareness. The Space Force was created in 2019 out of Air Force Space Command.
The U.S. Air Force, written by Robert MacArthur Crawford in 1939 and known everywhere by its first line, “Off we go into the wild blue yonder.” It was originally titled The Army Air Corps and renamed when the service became independent in 1947.
Roughly $233 billion for fiscal year 2026 as enacted. The fiscal year 2027 request rose sharply to $267.7 billion, part of a Department of the Air Force topline of $338.8 billion that also funds the Space Force.
