Historical Developments

3rd centuryBalloon warfare emerged as lighter-than-air military aviation 1826 years ago

The article dates the progression from kites to balloon warfare to the third century. Balloons later carried artillery observers, giving armies elevated observation of the battlefield.

early 20th centuryAirships (notably zeppelins) entered military service 126 years ago

Airships, particularly zeppelins, were put to military use in the early years of the twentieth century. They were used for bombing cities, extending warfare from observation to aerial attack.

1911Heavier-than-air aeroplanes first went to war in the Italo-Turkish War 115 years ago

Aeroplanes were used militarily for the first time in the Italo-Turkish War, initially for aerial reconnaissance. Aerial combat followed as aircraft were used to shoot down enemy reconnaissance planes, marking the birth of air-to-air fighting.

1914–18Belligerents of World War I developed fighter aircraft, air superiority and strategic bombing 112 years ago

During the First World War aircraft and zeppelins were used for strategic bombing, and the rise of fighter aircraft and air-to-air combat produced the doctrine of air superiority. Closer integration of attacking aircraft with ground operations, or battlefield support, also developed in this period.

1915The Fokker Eindecker introduced a synchronisation gear allowing a machine gun to fire through the propeller arc 111 years ago

The German monoplane could aim its gun simply by pointing the aircraft at an enemy, creating the forward-firing single-seat fighter and, with it, dedicated air-to-air combat as a distinct form of warfare.

1939–45Belligerents of World War II introduced airborne forces, missiles and precision-guided munitions 87 years ago

The Second World War saw an expansion of strategic bombing alongside the introduction of airborne forces, missiles and early precision-guided munitions. Aircraft carriers became especially important for projecting air power across oceans.

1940Britain's Dowding System linked radar, observers and ground control to direct fighters in real time 86 years ago

The integrated air defence network let a numerically smaller fighter force meet German raids efficiently during the Battle of Britain, establishing ground-controlled interception as the basis of modern air defence.

1943Long-range P-51 Mustang escorts extended fighter cover deep into enemy territory for the first time 83 years ago

Drop tanks gave escort fighters the range to accompany bombers to distant targets and back, drawing the German fighter force into attritional battles it could not sustain and shifting air superiority over Europe to the Allies.

1950The Korean War produced the first sustained jet-versus-jet air combat, centred over MiG Alley 76 years ago

American F-86 Sabres and Soviet-flown MiG-15s fought at transonic speed along the Yalu River, establishing pilot training and tactics as decisive factors in jet combat and shaping fighter doctrine for the following generation.

1958A Republic of China Air Force F-86 fired the first infrared-guided air-to-air missile used in combat 68 years ago

An early Sidewinder missile downed a People's Liberation Army MiG-17 over the Taiwan Strait, opening the missile era of air combat and prompting the Soviet Union to reverse-engineer an unexploded round recovered from the encounter.

1967Israel opened the 1967 war with a pre-emptive strike that destroyed most of Egypt's air force on the ground 59 years ago

The first hours of Operation Focus caught Egyptian aircraft lined up on their runways, establishing air supremacy before the ground war began and showing that a first strike could decide a conflict's outcome within a single morning.

The doctrine influenced air forces well beyond the Middle East
1969The US Navy founded its Fighter Weapons School, later known as Topgun 57 years ago

Poor air-to-air kill ratios over Vietnam prompted dedicated adversary training and a review of missile reliability, more than doubling the exchange ratio in the war's final air battles and establishing a model other air forces later copied.

1971The Indian Air Force achieved air superiority over both fronts of the 1971 war with Pakistan 55 years ago

Sustained strikes against Pakistani airbases and numerical and doctrinal advantages produced the largest air campaign fought over the subcontinent since the Korean War, shaping both countries' air force doctrine for decades afterward.

Recent Developments

June 2025The Israeli Air Force established air superiority over Iranian airspace within days of opening Operation Rising Lion last year

Stealth F-35I aircraft and standoff strikes suppressed Iranian air defences and grounded much of its fighter force, allowing sustained Israeli sorties deep into Iranian territory with limited air-to-air resistance over the following 12 days.

Iran's air force mounted little resistance in the air
May 2025Pakistan's air force claimed to have downed multiple Indian jets using Chinese-made J-10C fighters firing PL-15 missiles last year

Days of aerial engagement followed a terrorist attack in Kashmir and India's retaliatory strikes, producing the largest beyond-visual-range air battle in decades; India did not confirm the scale of its own losses.

The engagement drew global attention to Chinese-made air combat exports
March 2025The US Air Force selected Boeing's F-47 as its Next Generation Air Dominance fighter last year

The contract award ended a competition with Northrop Grumman for a crewed sixth-generation fighter intended to operate alongside autonomous collaborative combat aircraft, pitched as restoring a generational lead over Chinese fighter designs.

2025India opened its fifth-generation fighter prototype contract to private industry last year

Under the cabinet-approved execution model for the Advanced Medium Combat Aircraft, private firms could bid alongside state-run Hindustan Aeronautics to build the prototype, a departure from India's historical reliance on the public sector for combat aircraft.

2025Turkish Aerospace Industries pursued export partners for the KAAN fifth-generation fighter last year

Indonesia and Azerbaijan were among the countries discussing production co-operation or purchase of the aircraft, part of an effort to build an export base for Turkey's first indigenous fighter beyond its domestic air force order.

2025South Korea's arms procurement agency moved the KF-21 Boramae from development into low-rate production last year

The Defence Acquisition Programme Administration advanced the domestically designed fighter toward serial output while Indonesia's contribution to the joint development cost remained substantially in arrears, straining a partnership agreed a decade earlier.

December 2024The UK, Italy and Japan signed a treaty establishing the Global Combat Air Programme's joint organisation 2 years ago

The agreement created a permanent international body to govern development of a shared sixth-generation fighter intended to replace Typhoon and F-2 aircraft from around 2035, with production work divided across the three countries.

Saudi Arabia continued to seek a role in the programme
December 2024China flew two new-generation fighter prototypes in public for the first time 2 years ago

A tailless, three-engine design from Chengdu and a separate heavy fighter from Shenyang appeared over Chengdu within the same day, the first public evidence of Chinese sixth-generation fighter development and a break from established twin-tail layouts.

Western defence officials treated the sighting as a significant surprise
November 2024China displayed the J-35A stealth fighter publicly for the first time 2 years ago

The twin-engine, carrier-capable design shown at the Zhuhai Airshow gave China a second stealth fighter type alongside the J-20 and positioned an export variant to compete with the F-35 in markets closed to US arms sales.

August 2024Australia hosted Exercise Pitch Black, drawing fighter squadrons from across the Indo-Pacific and beyond 2 years ago

The biennial exercise brought together air forces from Asia, Europe and the Pacific for large-scale combined air combat training over northern Australia, reflecting its growth into one of the largest multinational fighter drills held anywhere.

2020Drone warfare proliferated after the Second Nagorno-Karabakh War 6 years ago

Relatively cheap unmanned equipment spread widely in the twenty-first century, with proliferation accelerating after the start of the Second Nagorno-Karabakh War in 2020. This shifted the balance of air combat capability towards states and actors unable to field manned air forces.

1991The 1991 Gulf War coalition demonstrated air superiority achieved almost entirely within days 35 years ago

Airborne early warning control, stealth aircraft and beyond-visual-range missiles combined to destroy Iraq's air force and air defences at a lopsided exchange ratio, setting a template later air forces sought to replicate.

The F-117 Nighthawk flew its first combat missions
1982Israel destroyed Syria's air defence network and much of its air force in a single operation over Lebanon's Bekaa Valley 44 years ago

Decoy drones drew Syrian radars to switch on, allowing jamming and strikes to blind the integrated air defence system before fighters engaged; Syria lost dozens of aircraft for negligible Israeli losses in the air battles that followed.
