Vought F-8 Crusader

Variants

XF8U-1 (XF-8A) – the two original unarmed prototypes - V-383.
F8U-1 (F-8A) – first production version, J57-P-12 engine replaced with more powerful J57-P-4A starting with 31st production aircraft, 318 built.
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.
XF8U-1T – one XF8U-2NE used for evaluation as a two-seat trainer.

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 - V-408.
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, AN/APQ-83 radar retrofitted during later upgrades. 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, incorporation of AN/APQ-83 radar. First flight: 16 February 1960, 152 built.
YF8U-2N (YF-8D) – one aircraft used in the development of the F8U-2N.
YF8U-2NE – 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, AN/APQ-94 radar replaced AN/APQ-83 radar in earlier F-8D. 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, incorporated AN/APQ-104 radar, an upgraded version of AN/APQ-94. A total of 42 built.
F-8H – upgraded F-8D with strengthened airframe and landing gear, with AN/APQ-84 radar. A total of 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, with AN/APQ-124 radar. A total of 136 rebuilt.
F-8K – upgraded F-8C with Bullpup capability and J57-P-20A engines, with AN/APQ-125 radar. A total of 87 rebuilt.
F-8L – F-8B upgraded with underwing hardpoints, with AN/APQ-149 radar. A total of 61 rebuilt.
F-8P – 17 F-8E(FN) of the Aéronavale underwent a significant overhaul at the end of the 1980s to stretch their service life another 10 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 - V-392.
F8U-1P (RF-8A) – unarmed photo-reconnaissance version of F8U-1E, 144 built.
RF-8G – modernized RF-8As.
LTV V-100 – revised "low-cost" development based on the earlier F-8 variants, created in 1970 to compete against the F-4E Phantom II, Lockheed CL-1200 and F-5-21 in a tender for U.S. Military Assistance Program (MAP) funding. The unsuccessful design was ultimately only a "paper exercise."
XF8U-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 - V-401.
