The Gloster Meteor was the first British jet fighter and the only Allied jet fighter to see combat during World War II. Developed by the British company Gloster Aircraft Company, it made its first flight in 1943 and entered service in 1944. The Meteor was powered by two Rolls-Royce Derwent engines and was primarily used for intercepting enemy aircraft. After the war, the Meteor continued to serve in various roles, including as a trainer and ground-attack aircraft. It was used by several air forces around the world, including those of the Royal Air Force and Royal Australian Air Force. The Meteor's design influenced future jet aircraft development.
