Air Force History

The U.S. Air Force is younger than the Army or the Navy — but the airpower story it tells reaches back to the very first powered flight in 1903 and runs through every major American conflict of the modern era. The names, aircraft, and pivotal moments below are what BMT expects you to know, and they explain why today's Air Force looks the way it does.

This section has a lot of dates, but the through-line is simple: airpower went from an unproven oddity to a co-equal fighting service in roughly forty years, then to the dominant arm of modern combined-arms warfare in the eighty after that. The lessons learned along the way still shape how the Air Force trains, equips, and fights.

Background of the Air Force

American military aviation began with the Wright brothers — visionaries and practical businessmen who, soon after patenting their flying machine in 1906, proposed it to the U.S. government as a war machine.

In 1907, with President Theodore Roosevelt's backing, the Army established the Aeronautical Division within the Signal Corps. The Wright Brothers signed a contract to build the Army its first plane on 19 February 1908, just two months after their proposal. Early aviation was deadly: less than a year later, Lt. Thomas Selfridge became the first military officer in the Air Service to die when a plane piloted by Orville Wright crashed.

The Aviation Section (1914–1918) followed, operating airplanes and lighter-than-air machines and standing up the first U.S. pilot training — much of it taught by Wilbur Wright himself. Lt. Frederick Humphries soloed to become the first Army pilot. By 1911, twenty-one young officers were in pilot training within the new division.

Two of those early aviators would shape the rest of American airpower.

Gen. Henry "Hap" Arnold

Arnold became the fourth Army Aviator, surviving the terrors and errors of early training to eventually lead the Air Service into becoming a separate Air Force. He commanded Rockwell Field, California, where most of the great WWII commanders trained — including Ira Eaker and Carl "Tooey" Spaatz, both of whom became key WWII air commanders.

Gen. William "Billy" Mitchell

Mitchell entered WWI with a strong combat record, became the youngest captain ever assigned to the American general staff, and spent the rest of his career campaigning for an independent Air Force. He believed airpower's full potential came from attacking an enemy nation's ability and willingness to wage war. He was right — and was eventually court-martialed for saying so too publicly, without using the chain of command.

World War I (1914–1918)

When war engulfed Europe in 1914, America lagged badly in airpower. The U.S. had pilots but no front-line aircraft of its own at the end of 1916. So American pilots flew Allied airplanes — most famously with the Escadrille Lafayette, a squadron of Americans flying for the French Aviation Service. Over 200 U.S. pilots served in this unit, shooting down 57 German planes for just 9 losses.

When the U.S. Air Service finally entered the war directly, it scored 756 kills against enemy aircraft and lost 289 of its own planes and 237 pilots killed. By the war's end in November 1918, its most lasting product was the generation of leaders — Arnold, Eaker, Spaatz, Mitchell — who would build the Air Force of WWII.

World War II (1939–1945)

WWII transformed American airpower. Increased budgets, faster development, and the realities of a global war forced the Army Air Corps from a constrained arm into the dominant force that would end the war.

Hitler's forces overran Europe starting in September 1939. The German Blitzkrieg used bombers as flying artillery, terror-bombed cities, and swept the skies clean with the Luftwaffe. Britain and France were on the defensive within months.

Pearl Harbor — 7 December 1941

The Japanese attack on Pearl Harbor brought the U.S. officially into the war. The Army Air Corps' first job was to gear up plane production fast enough to fight a war on two fronts.

The Doolittle Raid — 18 April 1942

To stop the bleeding morale on the U.S. home front, Jimmy Doolittle planned an audacious mission: launch sixteen twin-engine B-25 bombers fully loaded from a Navy aircraft carrier and strike targets in Tokyo. The plane needed to take off in 500 feet, fly 2,000 miles, and drop a 2,000-pound bomb load — none of which had been tried before.

The Doolittle Raiders took on enormous risk: U.S. carriers had to come within 450 miles of Japan, the B-25s had no backup landing site if China turned hostile, and any premature discovery would mean total annihilation. Several pilots were lost, three were executed by the Japanese after capture, and Doolittle was haunted by every loss. But the raid succeeded — Tokyo was hit, and Americans had something to celebrate when they desperately needed it.

D-Day — 6 June 1944

D-Day was the most critical day of the war. The U.S. invaded Hitler's Fortress Europe across the Normandy beaches, and the brilliance and heroism of low-level air missions made the landings possible. The U.S. had already gained air superiority over the Luftwaffe — only two German fighters reached Normandy's beaches that day, and German reinforcements couldn't move under hostile skies. Over 17,000 airborne troops parachuted in behind enemy lines to secure roads and fight enemy defenses.

The Tuskegee Airmen

The Tuskegee Airmen were the first African American military pilots in U.S. history. They formed the 332nd Fighter Group and the 477th Bombardment Group of the U.S. Army Air Forces, with all training conducted at Tuskegee University in Alabama. The group also included five Haitian pilots, one Trinidadian, and a Hispanic airman from the Dominican Republic.

The 99th Pursuit Squadron was the first Black flying squadron to deploy overseas, initially flying P-40 Warhawks before transitioning to P-51 Mustangs. The "Red Tails" nickname came from the red-painted tails on their P-47s and the red bands and propeller spinners on their P-51s.

From 1941 to 1946, 992 Tuskegee pilots were trained. 355 deployed overseas and 84 lost their lives. They flew 1,578 combat missions and 179 bomber-escort missions, with one of the best escort records of any P-51 group in the 15th Air Force — losing bombers on only seven missions across the entire war.

Women's Air Service Pilots (WASPs)

The WASPs ferried aircraft from factories to combat squadrons. Between September 1942 and December 1944, they delivered 12,652 aircraft — nearly every type flown by the USAAF in the war. Many traditionalists objected to women flying military aircraft (especially four-engine bombers); the WASPs flew them anyway and set the precedent for the modern integrated Air Force.

End of the War in Europe

Germany surrendered on 2 May 1945. By that spring, German industry, oil, and rail had been pulverized by Allied air campaigns to the point that the Air Force had run out of meaningful targets. Three years of strategic bombing had paid off.

War in the Pacific — and the End

The Pacific theater required different tactics. The Army Air Force reorganized B-29 operations to the Mariana Islands and put Gen. Curtis LeMay in command of strategic bombing. Japanese fighters introduced ramming attacks and Kamikaze tactics, sending U.S. losses upward.

By mid-1945, fire raids had gutted Japanese cities but had not forced surrender. The U.S. dropped two atomic bombs to end the war:

• Hiroshima — 6 August 1945. A B-29 named Enola Gay dropped the bomb code-named "Little Boy." Roughly 100,000 people died instantly.
• Nagasaki — 9 August 1945. A B-29 named Bock's Car dropped the bomb code-named "Fat Man." Roughly 80,000 people died instantly.

Japan surrendered on 15 August 1945. The Allied victory came with a heavy bill: roughly 300,000 Allied lives saved by avoiding a mainland invasion, set against U.S. combat losses since Pearl Harbor of thousands of planes and 24,230 aircrew members.

A Separate Air Force — National Security Act of 1947

WWII proved that airpower deserved its own service. Congress passed the National Security Act of 1947, which took effect on 26 July 1947 and created the U.S. Air Force as an independent service of the U.S. military on 18 September 1947.

That date is one of the easier ones to remember — and the Air Force has been a co-equal service ever since.

Berlin Airlift (24 June 1948 – 11 May 1949)

The first major post-war Air Force test came almost overnight. The Soviet Union froze land access to Berlin, which sat inside the Soviet zone of occupation but was administered by the four Allied powers. The Soviets believed the Air Force lacked both the logistics and the courage to keep a city of millions supplied through the air alone for any meaningful length of time.

They were wrong. The Berlin Airlift ran for 15 months, flew 277,000 sorties, and delivered 2.3 million tons of cargo. The Soviet Union reopened the land routes in May 1949. Seventy-eight blockade runners died, including 31 Americans.

Korean War (25 June 1950 – 27 July 1953)

Korea was the first armed conflict of the Cold War. North Korean forces crossed the border in a surprise attack that nearly overran the south. China and the Soviet Union backed North Korea; the U.S., the United Nations, and other allies backed the South.

The Air Force's most decisive contribution came in air-to-air combat over MiG Alley, the airspace over far-northwestern North Korea. The U.S. F-86 Sabre and the Soviet-built MiG-15 were technologically comparable, but the F-86 outperformed the MiG because Air Force pilots had more combat experience — many had already shot down five or more aircraft in WWII.

The war ended on 27 July 1953 with an Armistice Agreement, but no formal peace treaty. The demilitarized zone at the 38th parallel remains one of the most heavily defended borders in the world to this day.

Vietnam War (1 November 1955 – 30 April 1975)

Vietnam was a war the U.S. fought with one hand tied. Political over-management, restrictive bombing rules, and unclear strategic goals hurt the U.S. effort and cost many lives.

Key problems: President Johnson did not want to lose South Vietnam to Communism, but also wanted to avoid escalation that might pull in China. The middle road forced pilots to operate at high altitudes (around 7,000 feet) where unguided bomb accuracy fell off badly. With no front lines, no fixed enemy strongpoints, and an enemy supply chain (the Ho Chi Minh Trail) hidden under jungle canopy, large bombing campaigns — Arc Light, Rolling Thunder, Barrel Roll, Steel Tiger, Linebacker — struggled to produce strategic effect.

What worked: Heavy, secret B-52 raids in Cambodia disrupted Communist movements. Forward Air Controllers (FACs) flying small, slow Cessnas at low altitude became the unsung heroes of the war, spotting and marking targets for bombers — many at the cost of their lives.

The cost: About 2,600 USAF personnel killed or missing. Over 2,257 USAF planes and helicopters lost, 60% to anti-aircraft artillery fire. The Vietnam War closed the age of aerial gunnery and taught the Air Force what worked (controlling the skies, precision ground engagement, operating in dense integrated air defenses) and what didn't (unclear objectives, political micromanagement, neglected pilot training).

1970s, 1980s, into the early 1990s

After Vietnam, the Air Force rebuilt for a different kind of war. Bomber pilots lost their dominance to fighter pilots. The service aggressively recruited women and minorities and integrated them throughout combat units. The Air National Guard and Reserve became key parts of every combat call-up.

New aircraft replaced the Vietnam-era fleet:

• F-15 Eagle — large, electronics-rich air-superiority fighter
• F-16 Fighting Falcon — nimble, less expensive dogfighter
• A-10 Thunderbolt II ("Warthog") — heavily armored close air support with a 30mm Gatling gun and tank-killing missiles
• B-1 Lancer — supersonic strategic bomber designed to penetrate enemy airspace at low level using terrain-following radar

The Air Force also invested heavily in command-and-control, intelligence collection, and the AWACS (Airborne Warning and Control System) — an aerial system that sorts friend from foe and directs aerial attacks. The C-5 Galaxy added strategic airlift capable of carrying outsized payloads anywhere in the world.

Stealth Aircraft

The Air Force's biggest closely-held secret of the era was stealth. Aircraft like the Lockheed F-117 Nighthawk and Northrop B-2 Spirit used special airframes, materials, and shaping to defeat radar, heat, and sound detection. Combined with the GPS satellite constellation and on-board radar/laser/infrared sensors, stealth aircraft could attack targets in any weather and largely avoid being engaged at all.

Persian Gulf War (2 August 1990 – 28 February 1991)

Iraq invaded Kuwait on 2 August 1990 under Saddam Hussein. The goal was Kuwait's oil. The Air Force response was fast: combat air patrols within 24 hours, the Army's 18th Airborne deployed within 7 days, and 1,100 aircraft moved to the battle zone within weeks.

The war had two phases:

• Operation DESERT SHIELD — the buildup of American forces in Saudi Arabia.
• Operation DESERT STORM — the 43-day air campaign followed by a 100-hour ground war (17 January – 28 February 1991).

DESERT STORM showed what precision airpower could do. In the first 24 hours the Air Force destroyed Iraq's air defense and communications networks; from there, low-level raids targeted headquarters, bridges, and railroads to cut off the Iraqi army from its commanders and supplies. A useful measure of how things had changed since WWII: in WWII, hitting one target took 108 B-17s dropping 648 bombs. In the Gulf War, it took one plane dropping one weapon.

By the time the ground war began, the Iraqi military had lost 50–75% of its strength. The U.S. flew 59% of all combat sorties (more than 50,000), moved nearly 100,000 passengers, and delivered 330 million pounds of cargo. Total Air Force losses in combat: 14 planes. The war also introduced the Joint STARS aircraft, used for the first time to detect and track enemy ground forces.

For the first time in modern combat, the Air Force proved itself an equal partner of land and sea power.

The Attacks of 9/11 — 11 September 2001

On 11 September 2001, terrorists hijacked four commercial airliners and used them as weapons. The attacks killed nearly 3,000 Americans — the first attack on U.S. soil since Pearl Harbor.

The seed of the attacks was a terrorist training network in Afghanistan, run by Al-Qaeda under Osama bin Laden and protected by the extremist Taliban government. The U.S. response launched the longest war in American history.

Operation Enduring Freedom

On 7 October 2001, less than a month after the attacks, the U.S. and the U.K. began offensive operations against Al-Qaeda and the Taliban. Strikes used USAF heavy bombers, Navy F-14s and F-18s, and Tomahawk cruise missiles.

The campaign showcased new tactics and technology. Small Special Forces teams found the enemy and painted targets with lasers for precision air strikes. Satellite-guided bombs improved accuracy further. "Bunker buster" weapons reached enemy fighters hiding in mountain caves. The Taliban lost their last major city, Kandahar, in December 2001.

Operation Enduring Freedom also marked the operational debut of unmanned reconnaissance drones at scale: Predator, Global Hawk, Reaper, Sentinel. Drones could loiter for 24 hours, fly at night and in bad weather, send real-time imagery to bombers, and (on later models) fire their own missiles.

Operation Anaconda

In March 2002, Combined Joint Task Force Mountain launched Operation Anaconda to destroy remaining Al-Qaeda and Taliban forces in the Khowst-Gardez region. Coalition aircraft dropped 177 precision-guided bombs and conducted strafing runs in the first 24 hours; 667 more bombs in support of ground troops two weeks later. The operation concluded on 16 March 2002.

Operation Iraqi Freedom

Operation Iraqi Freedom began on 20 March 2003 following intelligence that Saddam Hussein was stockpiling weapons of mass destruction and sheltering Al-Qaeda. After Hussein refused a 48-hour ultimatum to leave the country, the U.S. launched the "Shock and Awe" campaign — the highest opening tempo in modern history, with more cruise missiles launched on the first day than in the entire Gulf War.

The Air Force flew constant combat air patrols, airlift, ISR, aerial refueling, aeromedical evacuation, and combat search and rescue. Joint Terminal Attack Controllers (JTACs) provided command and control for close air support across the campaign.

Saddam Hussein was captured on 13 December 2003 and later executed. Iraq held democratic elections in December 2005. The cost was nearly 5,000 U.S. troops killed and over 32,000 wounded. The last U.S. troops left Iraqi territory on 18 December 2011.

Afghanistan

The war in Afghanistan, started in 2001, expanded into a multi-decade campaign. NATO forces continued to battle a widespread Taliban insurgency that spilled over into the tribal regions of neighboring Pakistan.

On 21 May 2012, NATO leaders signed off on President Obama's exit plan for Afghanistan, calling for an end to combat operations in 2013 and a withdrawal of U.S. military force by the end of 2014.

In late 2014, a new threat emerged: the Islamic State of Iraq and the Levant (ISIS / ISIL), a radical Sunni Jihadist organization that seized territory in Syria and northern Iraq. ISIS executed citizens of the U.S. and Britain and committed mass atrocities — even Al-Qaeda repudiated them. President Obama authorized Operation Inherent Resolve, a partner-nation campaign of targeted air strikes over Syria and Iraq aimed at degrading and defeating ISIS.

On 29 February 2020, the U.S. and the Taliban signed an agreement to bring an end to the 18-year-long war. On 31 August 2021, the final U.S. service member departed the main airport in Kabul.

Historical Perspective

From Kitty Hawk to Afghanistan, airpower's record emphasizes a few durable themes. Innovation in technology, tactics, and strategy has to be sustained by training, logistics, supply, and support infrastructure — none of those parts works without the others. History doesn't hand you ready-made lessons, but it offers inspiration, insight, and examples worth studying. Today's Airmen draw from a heritage of sacrifice, valor, and hard-earned victory that began with the Wright brothers and continues every day.

Potential Adversaries

The National Security Strategy (NSS), December 2017 categorizes potential adversaries into three main groups:

• Major powers — China and Russia. China seeks to displace U.S. influence in the Indo-Pacific, expand its own state-driven economy, and reshape the region in its favor — including by leveraging the U.S. economy and U.S. universities. Russia aims to weaken U.S. influence, divide America from its partners and allies, and reshape the global order through investments in conventional military, nuclear, and cyber capabilities.
• Rogue states — North Korea and Iran. A repressive dictatorship and a state sponsor of terrorism, respectively. Both are pursuing missile and nuclear capabilities that threaten the U.S. and its allies.
• Jihadist terrorist groups. Although ISIS and Al-Qaeda have suffered battlefield defeats, the threat continues through cells and affiliates worldwide.

Countering these adversaries requires integrating every instrument of national power — political, economic, and military — and the credible strength of U.S. alliances.

Summary

The Air Force is younger than its sister services, but its record runs from the first powered flight to the longest war in American history. The Berlin Airlift, the Korean and Vietnam wars, Desert Storm, the response to 9/11, and the campaigns in Iraq, Afghanistan, and against ISIS each expanded what airpower could do — and depended on Airmen at every level. The people of the Air Force are its most valuable resource, and your service joins a long line of those who have advanced the mission no matter the job.
