Aircraft of World War II

Air power played a central role in World War II, and the conflict drove rapid advances in military aircraft. The main combat types fell into broad categories. Fighters were fast, agile aircraft designed to attack enemy planes and protect friendly ones, while bombers were larger machines built to carry explosives to targets on the ground. The performance of these aircraft, and the ability to control the air above a battlefield, often shaped the outcome of campaigns on land and sea.

Several aircraft became famous symbols of the war. On the British side, the Supermarine Spitfire and the Hawker Hurricane were the fighters that defended Britain during the Battle of Britain in 1940. The German air force, the Luftwaffe, fielded the Messerschmitt Bf 109 as its principal fighter. The American P-51 Mustang became a celebrated long-range fighter able to escort bombers deep into enemy territory. Heavy bombers such as the American B-17 Flying Fortress and the B-29, together with British night bombers, carried out the large-scale bombing campaigns of the war.

Beyond fighters and bombers, the war saw a wide range of specialised aircraft for reconnaissance, transport, naval operations and ground attack. Aircraft launched from carriers transformed warfare at sea, particularly in the Pacific. The intense competition spurred innovations that pushed aircraft to higher speeds and altitudes, and by the war's end the first jet-powered aircraft had entered service, pointing toward the future of aviation.
