During World War II, the jet aircraft moved from the concept phase to development. The first operational jet-powered aircraft, the German Messerschmitt Me 262, entered service in 1944 and was used in combat against Allied aircraft. The Allied powers also developed their own jet aircraft, such as the British Gloster Meteor and the American Bell P-59 Airacomet. The development of jet aircraft revolutionized aerial warfare and paved the way for modern aviation technology.
