The Gloster Aircraft Company, Limite, known locally as GAC, was a British aircraft manufacturer. The company produced a famous lineage of fighters for the Royal Air Force (RAF); the Grebe, Gladiator, Meteor and Javelin. It also produced the Hawker Hurricane and Hawker Typhoon for the parent company Hawker Siddeley. Gloster produced the first British gas turbine-powered aircraft: the E.28/39 and the first British (and only gas-turbine-powered Allied aircraft to see service in World War II) production jet fighter in the Meteor. Gloster's test runway became famous for the first flight of Sir Frank Whittle's turbojet in the E.28/39 aircraft.
