Gloster produced the Gladiator biplane and during WWII built more than 6,000 Hurricanes & Typhoons. Gloster Meteor was the first Allied jet of the War and in 1952 the delta-winged Javelin was developed as an all-weather fighter that could fly above 50,000 feet. Gloster merged into Hawker Siddeley Aviation in 1963, and the name Gloster disappeared.
