The de Havilland DH.100 Vampire was a British jet-engined fighter of the Second World War, the second jet-powered aircraft commissioned by the Royal Air Force during the War (the first being the Gloster Meteor), although it was not used in combat. The Vampire served with front line RAF squadrons until 1955 and continued in use as a trainer until 1966. It also served with many air forces worldwide, and set several aviation firsts and records. Almost 3,300 Vampires were built, a quarter of them under licence in other countries.
