Known as "The Last Gunfighter," the Vought F-8 Crusader is a single-engine, supersonic, carrier-based air superiority jet aircraft designed and produced by the US aircraft manufacturer Vought. It was the last US fighter to have guns as its primary weapon. It possessed an innovative high-mounted variable-incidence wing, an area-ruled fuselage, all-moving stabilators, dog-tooth notching at the wing folds for improved yaw stability, and liberal use of titanium throughout the airframe.
