Vought XF8U-3 Crusader III
 The Vought XF8U-3 Crusader III was an aircraft developed by Chance Vought as a successor to the successful Vought F-8 Crusader program and as a competitor to the McDonnell Douglas F-4 Phantom II. Though based in spirit on the F8U-1 and F8U-2 and sharing the older aircraft's designation in the old Navy system the two aircraft shared few parts.
