YF8U-1 (YF-8A) - one F8U-1 fighter used for development testing.

YF8U-1E (YF-8B) - one F8U-1 converted to serve as an F8U-1E prototype.

F8U-1E (F-8B) - added a limited all-weather capability thanks to the AN/APS-67 radar, the unguided rocket tray was sealed shut because it was never used operationally, first flight 3 September 1958, 130 built.

YF8U-2 (YF-8C) - two F8U-1s used for flight testing the J57-P-16 turbojet engine.

F8U-2 (F-8C) - J57-P-16 engine with 16,900 lbf (75 kN) of afterburning thrust, ventral fins added under the rear fuselage in an attempt to rectify yaw instability, Y-shaped chin pylons allowing two Sidewinder missiles on each side of the fuselage, first flight 20 August 1957, 187 built. This variant was sometimes referred to as Crusader II.

F8U-2N (F-8D) - all-weather version, unguided rocket pack replaced with an additional fuel tank, J57-P-20 engine with 18,000 lbf (80 kN) of afterburning thrust, landing system which automatically maintained present airspeed during approach, first flight 16 February 1960, 152 built.

YF8U-2N (YF-8D) - one aircraft used in the development of the F8U-2N.

YF8U-NE - one F8U-1 converted to serve as an F8U-2NE prototype.

F8U-2NE (F-8E) - J57-P-20A engine, AN/APQ-94 radar in a larger nose cone, dorsal hump between the wings containing electronics for the AGM-12 Bullpup missile, payload increased to 5,000 lb (2,270 kg), Martin-Baker ejection seat, first flight 30 June 1961, 286 built.

F-8E(FN) - air superiority fighter version for the French Navy, significantly increased wing lift due to greater slat and flap deflection and the addition of a boundary layer control system, enlarged stabilators, 42 built.

F-8H - upgraded F-8D with strengthened airframe and landing gear, 89 rebuilt.

F-8J - upgraded F-8E, similar to F-8D but with wing modifications and BLC like on F-8E(FN), "wet" pylons for external fuel tanks, J57-P-20A engine, 136 rebuilt.

F-8L - F-8B upgraded with underwing hardpoints, 61 rebuilt.

F-8P - 17 F-8E(FN) of the AĆ©ronavale underwent a significant overhaul at the end of the 1980s to stretch their service life another ten years. They were retired in 1999.

F8U-1D (DF-8A) - several retired F-8A modified to controller aircraft for testing of the SSM-N-8 Regulus cruise missile. DF-8A was also modified as drone (F-9 Cougar) control which were used extensively by VC-8, NS Roosevelt Rds, PR; Atlantic Fleet Missile Range.

DF-8F - retired F-8A modified for target tug duty.

F8U-1KU (QF-8A) - retired F-8A modified into remote-controlled target drones

YF8U-1P (YRF-8A) - prototypes used in the development of the F8U-1P photo-reconnaissance aircraft.

F8U-1P (RF-8A) - unarmed photo-reconnaissance version of F8U-1E, 144 built.

RF-8A Crusader - Bu. 145882

RF-8G - modernized RF-8As

XF8U-1T - one XF8U-2NE used for evaluation as a two-seat trainer.

F8U-1T (TF-8A) - two-seat trainer version based on F8U-2NE, fuselage stretched 2 ft (0.61 m), internal armament reduced to two cannon, J57-P-20 engine, first flight 6 February 1962. The Royal Navy was initially interested in the Rolls-Royce Spey-powered version of TF-8A but chose the Phantom II instead. Only one TF-8A was built, although several retired F-8As were converted to similar two-seat trainers.

F8U-3 Crusader III - new design loosely based on the earlier F-8 variants, created to compete against the F-4 Phantom II, J75-P-5A engine with 29,500 lbf (131 kN) of afterburning thrust, first flight 2 June 1958, attained Mach 2.6 in test flights, canceled after five aircraft were constructed because the Phantom II won the Navy contract.
