History of aerial warfare

• 1. Introduction

  ›

  Aerial warfare first turned genuinely aggressive in 1849. Austrian imperial forces besieging Venice floated 200 paper hot air balloons toward the city, each carrying a bomb weighing between 24 and 30 pounds. The balloons were launched partly from land, partly from SMS Vulcano, a side-wheel steamer pressed into service as an improvised balloon carrier. Before the main launch, Austrian commanders used smaller pilot balloons to gauge the correct fuse timing. Then the wind changed. Most bombs missed Venice entirely. Some drifted back across Austrian lines. The Vulcano itself was nearly struck by its own released payload.

  That failed bombardment contains, in small form, the central problem of all aerial warfare. How do you make a weapon reach its target rather than your own people? From paper balloons and time fuses, this history runs across more than 170 years of invention, catastrophe, and escalation. What allowed simple observation to become lethal combat? What drove the belief that bombing cities from the air could win a war by itself? And how did the most expensive military technology in history eventually find its cheapest and most devastating form?

• 2. Imagination Before the Machine

  ›

  Zeus, in Greek mythology, could hurl thunderbolts down at earthbound humans. The ancient Greeks also told the story of Daedalus and Icarus, who fashioned wings and flew. Both images placed human beings above other human beings, with force flowing downward from that altitude. Warfare followed naturally from that arrangement in imagination, long before it could in reality.

  Jonathan Swift made the connection explicit in 1726, in the third book of Gulliver's Travels. The King of the flying island of Laputa suppresses rebellious subjects by bombarding them with heavy rocks dropped from the air. It sketches the essential advantage of height: an attacker from above is difficult to strike back at from the ground.

  Hans Christian Andersen, writing in 1840, gave the fantasy far more military detail in his story "The Wicked Prince." The story's conquering Prince orders a ship built for sailing through the air. Andersen describes it as gorgeously fitted out, covered with thousands of eyes; each eye is the barrel of a gun. The Prince touches a spring and thousands of bullets fly outward while the guns reload automatically. He later orders an improved model able to fire what Andersen calls "Steel Thunderbolts," and from thousands of these craft builds a massive air flotilla manned by his troops.

  H. G. Wells published The War in the Air in 1907, grasping the full strategic implications of aerial power. Wells predicted the devastating bombing of cities and the obsolescence of the surface battleship in naval warfare. Neither prediction came true in the war that broke out a few years after his book appeared. Both came true in the war that followed that one.

  At the 1907 Hague Convention, the Declaration Prohibiting the Discharge of Projectiles and Explosives from Balloons was ratified by the United States, Great Britain, and China. Nations were already trying to outlaw aerial bombardment before any of them had used it in a major war.

  ›

  Ancient China put aerial observation to military use first. A manned kite, flown over enemy territory, served as a platform for gathering intelligence and relaying communications. In roughly the second or third century, Chinese inventors developed the Kongming lantern. This prototype hot air balloon served as a military signaling device, carrying messages across distances no runner could match.

  The French Aerostatic Corps brought the balloon to a real European battlefield at the Battle of Fleurus in 1794. Their tethered balloon, L'entreprenant, gave French commanders a view no ground observer could achieve. Tethering was essential: a free balloon would drift wherever the wind carried it, and over enemy lines that meant capture. But tethering imposed its own limits. Balloons could not fly in bad weather, fog, or high winds. They made enormous targets.

  Thaddeus Lowe left private work in June 1861 and offered his services as an aeronaut to President Lincoln. His demonstration was simple: he flew a balloon over Washington, DC, and transmitted a telegraph message to the ground. Lowe was then introduced to the commanders of the topographical engineers. His first combat flight was a free-flight observation of Confederate positions at the First Battle of Bull Run in July 1861. At Fort Corcoran, he ascended and used flag signals to direct artillery fire on rebel encampments below.

  Lowe and other aeronauts formed the Union Army Balloon Corps. The corps operated at altitudes from 1,000 feet to as much as three and a half miles. Lowe insisted on tethered flight; a free balloon drifting over enemy lines meant the risk of being shot down and punished as a spy. When the war moved to the peninsula, heavy forests below made land-based balloon operations impossible. The corps loaded its balloons and gas generators onto a coal barge and operated from the Potomac River. At the Battle of Fair Oaks, Lowe spotted the enemy army advancing and dispatched a message calling for reserves. By August 1863, the corps was disbanded.

  The Confederate Army also flew balloons, but under a severe shortage of materials. Embargoes left them without conventional fabric, so Confederate forces fashioned their balloons from colored silk dress-making material. Gas supplies in Richmond, Virginia were infrequent. By the summer of 1863, all balloon reconnaissance on both sides of the American Civil War had ended.

  Italy put airplanes to use in actual warfare for the first time in 1911, during the Italo-Turkish War. Italian Army Air Corps Bleriot XI and Nieuport IV monoplanes bombed a Turkish camp at Ain Zara in Libya, signaling that the age of observation balloons was giving way to something faster and far more dangerous.

• 4. Hand Waves to Dogfights

  ›

  In the First World War, both sides began by using airplanes and tethered balloons for observation and artillery direction. Opposing pilots who spotted each other in the air would simply wave; neither had reason yet to prevent the other from watching. That civility did not survive the war's logic. An observer who could see where your artillery shells were landing made your opponent's guns more lethal. Stopping enemy observation became a military objective.

  French pilot Roland Garros and designer Raymond Saulnier solved the central mechanical problem of aerial combat: how to fire through a spinning propeller without destroying it. Their answer was deflector plates attached to the back of the propeller blades of a Morane-Saulnier monoplane. The plates deflected bullets away from the propeller. Garros scored three victories in April 1915 using this arrangement.

  Dutch aircraft designer Anthony Fokker developed a cleaner solution later that same year. His synchronizer interrupted the firing mechanism precisely when a propeller blade crossed in front of the barrel. German Leutnant Kurt Wintgens used a synchronized gun-equipped fighter to score the first known victory with this technology, on the 1st of July 1915. The Allies developed their own synchronization gears shortly afterward. Aerial combat, the rapid maneuvering fight that pilots called dogfighting, followed from there.

  German ace Oswald Boelcke codified what pilots had learned by painful trial and error into eight essential rules of aerial combat, the Dicta Boelcke. By 1916, these doctrines were already shaping how air supremacy shifted between German and Allied forces. New aircraft designs continually changed which side held the advantage, and new models on one side forced responses on the other.

  Germany used Zeppelin airships and later heavy bombers such as the Gotha to drop bombs on Southern England. Both sides flew aircraft for maritime reconnaissance, antisubmarine warfare, and the dropping of propaganda over enemy lines. By the war's end, the airplane had sorted itself into distinct types: bombers, fighters, and reconnaissance aircraft.

  Biplanes, the dominant aircraft of 1918, would remain central to air forces for two more decades. They flew in conflicts including the Spanish Civil War before metal-framed monoplanes finally replaced them.

• 5. The Bomber Gets Through

  ›

  Giulio Douhet, an Italian general, published The Command of the Air in 1921. The book offered the first complete theory of winning a future war entirely from the air. Douhet believed that aviation could bypass the grinding attrition of World War I. Instead of fighting through enemy armies, future commanders could fly over them and strike civilian populations directly. Those populations, Douhet believed, would pressure their governments into surrender.

  Sir Hugh Trenchard in Britain reached parallel conclusions after the war. In the interwar years, Britain and the United States became the most enthusiastic advocates of strategic bombing theory. Each nation built specialized heavy bombers for this specific purpose. Stanley Baldwin captured the doctrine's central claim in a phrase that circulated widely: "the bomber will always get through." The argument was that no defense could stop enough bombers from delivering destruction on enemy cities. Nations began measuring air force power by the number of heavy bombers each could field, a competition strategists called the "bomber gap."

  General Billy Mitchell in the United States took a different angle. He saw aerial power as a means of extending the striking force of naval surface fleets. On the 21st of July 1921, a squadron of bombers under his command sank the ex-German battleship SMS Ostfriesland using aerial bombs alone. The ship was stationary and defenseless during the exercise. Its destruction made the point clearly: aircraft could threaten even the most heavily armored warships.

  Marine Corps aviators fighting insurgents in Haiti, the Dominican Republic, and Nicaragua during what historians call the Banana Wars found a practical application that formal theory had not produced. Marines in Haiti began experimenting with dive bombing. Those in Nicaragua perfected it. Marine aviators were the first to incorporate the technique formally into their tactical doctrine.

  Germany was forbidden from possessing an air force by the World War I armistice. The German military trained pilots clandestinely by forming the Deutscher Luftsportverband, a flying enthusiast's club that provided cover for military instruction. Some German pilots were sent to the Soviet Union for additional training. A trained air force stood in reserve, ready as soon as political permission was given. That force became the Luftwaffe.

  By 1939, the metal-framed monoplane with liquid-cooled engines had replaced the biplane across most of the world's air forces. Top speeds had tripled since 1918 and operating altitudes had doubled. The air forces that went to war in September 1939 were almost unrecognizable from those that had demobilized twenty years earlier.

• 6. The Second Front

  ›

  Britain launched its strategic bombing campaign in 1940. Early British bombers were twin-engined designs. The 1939 Battle of the Heligoland Bight had already shown how vulnerable they were to fighter attack in daylight. Royal Air Force Bomber Command shifted to area bombing at night. Later in the war, pathfinder tactics, radio location, and ground mapping radar became available. These tools allowed specific targets to be struck with far greater precision.

  When the United States Army Air Forces arrived in England in 1942, American commanders believed they could carry out successful daylight raids. The US Eighth Air Force flew high-altitude, four-engined bombers with stronger defensive armament. American doctrine held that tight formations of heavy bombers could achieve air superiority without escort fighters. They targeted chokepoints in the German war economy: oil refineries and ball bearing factories. In 1943, missions that penetrated beyond the range of fighter cover produced loss rates as high as twenty percent. The Allies lost 160,000 airmen and 33,700 planes during the war; nearly 68,000 of the dead were American.

  Stalin's prewar purges had weakened the Soviet Air Forces significantly. When Germany invaded in June 1941, losses were enormous. But the Soviet Air Forces were large enough to absorb those losses and keep fighting. By 1943, Soviet factories were producing considerably more aircraft than Germany. At the Battle of Kursk, the Soviets fielded twice as many aircraft as the Luftwaffe could muster. That numerical advantage allowed Soviet forces to drive the Germans back and eventually carry the war into Germany itself.

  Albert Speer, the German armaments minister, offered the most concise verdict on the Allied bombing campaign: it created "a second front in the air." Strategic bombing by non-atomic means did not win the war on its own. Nor did it break civilian morale in Germany or Japan. Despite the campaign, Speer managed to increase German armaments production through mid-1944. But the defense against bombing consumed enormous resources: antiaircraft guns, fighters, radars, searchlights, manpower, ammunition, and fuel. On the Allied side, the effort diverted material and personnel away from the Battle of the Atlantic.

  In June 1944, Boeing B-29 Superfortresses launched from China bombed Japanese factories. From November 1944, increasingly intense raids flew from bases much closer to Japan. Tactics shifted from high-altitude attempts to lower-altitude incendiary attacks. Many Japanese cities were devastated. In August 1945, B-29s dropped atomic bombs on Hiroshima and Nagasaki while Soviet forces invaded Manchuria. Japan surrendered unconditionally.

  Some Soviet factories had been relocated so far into the interior that Luftwaffe bombers could not reach them. Soviet armaments output continued to grow throughout the war even as Germany's came under increasing pressure from the air.

• 7. The Carrier Takes Command

  ›

  On the 18th of January 1911, civilian pilot Eugene Ely landed on a platform attached to the cruiser USS Pennsylvania in San Francisco harbor. Two months earlier he had proved that flight from a warship was possible; this second proof, that landing back on one was also possible, completed the concept. It would transform naval warfare within three decades.

  Japanese carrier-based aircraft opened the Pacific War at Pearl Harbor in 1941, sinking several US battleships. Japanese land-based aircraft sank two large British warships in the same campaign. Carriers had not yet fully displaced the battleship, but the surface fleet's fundamental nature had changed.

  Fleet engagements at Coral Sea, Midway, the Bismarck Sea, and the Philippine Sea were decided by carrier-based aircraft. These battles were fought entirely out of gun range. The aircraft carrier had replaced the battleship as the dominant offensive naval weapon. The US also launched Army Air Forces land-based bombers from Navy carriers in a raid against Tokyo, an arrangement that showed how far the carrier's function had expanded from its origins.

  The Yamato, described as the most powerful battleship ever built, illustrated what the new order meant. It was first turned back by light escort carrier aircraft, then later sunk due to its own lack of air cover. Surface-based patrol aircraft such as the Consolidated PBY Catalina and the Short Sunderland hunted submarines and surface fleets across ocean approaches. In the Battle of the Atlantic, escort carriers ran antisubmarine patrols that helped shift the naval balance.

  Blimps hunted submarines in the Atlantic. Battleships and cruisers carried their own aircraft for observation and light raids. The principle of watching from above had spread to every layer of naval warfare, from the largest fleet carrier to the smallest convoy escort.

• 8. Precision and the Drone

  ›

  The Korean War brought jet aircraft to the forefront of air combat for the first time. In 1950, North Korea began flying Soviet-made MiG-15 fighters with near-sonic swept-wing speeds, quickly overwhelming the propeller-driven aircraft it had previously relied on. The United States rushed in the North American F-86 Sabre in December 1950. The two aircraft were closely matched in capability. The MiG flew higher, to 50,000 feet against the Sabre's 42,000. In level flight, both reached approximately 660 miles per hour. The MiG carried two 23-millimeter cannon and one 37-millimeter cannon. The Sabre answered with six .50-caliber machine guns, aimed with a more accurate radar-ranging gunsight.

  Soviet Air Force pilots, known to US flyers as "honchos," flew the most capable MiG aircraft in Korea. The United Nations suspected Soviet involvement but chose not to acknowledge it publicly, to avoid direct confrontation with the Soviet Union and China. After the war, the US Air Force claimed 792 MiG-15s destroyed by Sabres for the loss of 78. Later research reduced this to 379 victories, still higher than the 345 losses shown in Soviet records.

  The Korean War was also the first conflict where the helicopter saw extensive use. While the Sikorsky YR-4 had flown in World War II, helicopters were rare in that war; Jeeps like the Willys MB remained the primary means of removing wounded soldiers from the battlefield. In Korea, helicopters including the Sikorsky H-19 took over the non-combat medical evacuation role.

  The Lockheed U-2 was built in great secrecy, designed to fly at altitudes the United States believed no Soviet missile could reach. It was expected to be invulnerable to defensive measures. When the Soviets shot down a U-2 piloted by Gary Powers using a surface-to-air missile, that assumption collapsed. Speed and altitude alone, it became clear, were not sufficient protection.

  The Gulf War of 1991 demonstrated what precision-guided weapons and air superiority could together accomplish. Initial strikes used Tomahawk cruise missiles launched from ships, Lockheed F-117 Nighthawk stealth bombers armed with laser-guided bombs, and aircraft carrying anti-radar missiles. Iraq's air defense network collapsed. By the end of the fifth week, allied forces had flown more than 88,000 combat missions and dropped over 88,000 tons of bombs. The strike force of more than 2,250 combat aircraft included 1,800 American planes.

  The Russian invasion of Ukraine in 2022 introduced a new category of aerial weapon. Small, commercially available civilian drones, mostly quadcopters, were modified to drop grenades or fly directly into targets and self-destruct. These weapons differed from earlier unmanned aircraft fundamentally: they were cheap, widely available, and required little space and few resources to operate. An operator faced no personal risk. Their precision was high and their cost a fraction of traditional weapons. Aerial attack had become accessible to small units and civilian combatants, not only state air forces.

  On the 7th of May 2025, Indian and Pakistani fighter jets exchanged long-range beyond-visual-range missiles for over an hour. Participants described it as the largest aerial BVR engagement in modern history. Pakistani forces employed the PL-15 air-to-air missile, whose effective range had been underestimated by Indian intelligence. Pakistan also deployed surface-to-surface missiles including the Fatah-2 and Hatf-1; these strikes failed to achieve their intended objectives. Indian air defense systems intercepted a majority of incoming projectiles. The Indian Air Force subsequently established air superiority over significant portions of Pakistani airspace through a campaign of Harpy and Harop drone strikes against Pakistani radar and missile installations. Beyond-visual-range missiles, dedicated anti-radar drones, and surface-to-surface missiles had each found a distinct task in that single conflict, with none of the others able to cover it alone.
