F4H-1P (RF-4B)
Tactical reconnaissance version of F-4B for United States Marine Corps, nose stretched 4 ft 9 in (1.4 m), smaller AN/APQ-99 radar. Three camera bays typically carried KS-87 forward oblique/vertical camera on Station 1, KA-87 low-altitude camera on Station 2, and KA-55A or KA-91 high-altitude panoramic camera on Station 3. Also carried AN/APQ-102 reconnaissance SLAR, AN/AAD-4 infrared reconnaissance system, and ALQ-126ECM suite. The KS-72 or KS-85 cameras were on rotating mounts and could be aimed in flight which improved upon the earlier RF-4C which could only be aligned on the ground.[3] In 1975, modernized under Project SURE (Sensor Update and Refurbishment Effort); 46 built. Retired in 1990. 4 lost in Vietnam.[4] First flown 12 March 1965.[5]

F-110A
The original US Air Force designation for the F-4C.
F-4C
Two-seat all-weather tactical fighter, ground-attack version for the United States Air Force; supported a wide spectrum of weapons including AIM-4 Falcon, AGM-12 Bullpup, and nuclear weapons; wider main wheel tires resulted in distinctive wing bulges; J79-GE-15 engines with provision for cartridge start; boom refueling instead of Navy's probe and drogue refueling; AN/APQ-100 radar; duplicated flight controls in the rear cockpit. The aircraft exceeded Mach 2 during its first flight on 27 May 1963; 583 built.
EF-4C Wild Weasel IV
F-4Cs converted into Wild Weasel ECM aircraft. Equipped with AN/APR-25RHAWS, AN/APR-26 missile launch warning system, ER-142 ECM receiver, and AN/ALQ-119 external ECM pod. Armed with AGM-45 Shrike anti-radiation missiles and cluster bombs but unable to carry the AGM-78 Standard ARM missile. A total of 36 were converted.[6] Many survivors were reverted to F-4C.

RF-4C
All-weather tactical reconnaissance version for the US Air Force, AN/APQ-99 (later AN/APQ-172) radar. Equipped similar to RF-4B but with a wider choice of camera fits, including a centerline pod for the gigantic HIAC-1LOROP (Long Range Oblique Photography) camera, capable of taking high-resolution images of objects 100 miles (160 km) away. Many aircraft were refitted with a more spacious bulging streamlined nose. A sub-variant, to be designated RF-4C(H) was proposed as a night "hunter" aircraft using infrared equipment instead of cameras under Operation Shed Light. In the end, none were converted. While usually unarmed, RF-4Cs retained the ability to carry a nuclear weapon on the centerline pylon. Additionally, the RF-4Cs of the Alabama Air National Guard, Nevada Air National Guard and Fighter Weapons School were modified to carry the AIM-9 Sidewinder missile. These modernized RF-4Cs of the Alabama and Nevada Air National Guard participated in the Gulf War; 503 built.

F-4E
USAF version with an integral M61 Vulcan cannon in the elongated RF-4C nose, AN/APQ-120 radar with smaller cross-section to accommodate the cannon, J79-GE-17 engines with 17,900 lbf (79.379 kN) of afterburner thrust each. Late-series aircraft equipped with leading-edge slats to improve maneuverability at the expense of top speed under the Agile Eagle program. Starting with Block 53, aircraft added AGM-65 Maverick capability and smokeless J79-GE-17C or -17E engines. First flight 1 August 1965. The most numerous Phantom variant; 1,370 built.
F-4E Kurnass 2000

The latest in a long line of F-4 variants, the Terminators are a batch of Turkish Air Force F-4Es, modernized by Israel on the pattern of the Kurnass 2000. They differ from the existing F-4E airframe in a number of key areas, including new attachment fittings to better handle modern weaponry, stronger wing fold ribs, an updated canopy sill bar, and the replacement of some 20km of wiring (reducing weight by 750 kg) as well as most hydraulic and pneumatic lines and hoses.[11] A plan to increase the turn-rate and longitudinal stability of the Kurnass/Terminator derivatives through the installation of fuselage strakes over the engine inlets was abandoned after testing, and never saw installation on operational aircraft. [12]
The most radical changes occurred in the avionics department. All 2020s have been fitted with vastly updated suite, including MFDs (multifunction displays) as standard, and incorporating a number of new technologies, such as the new Kaiser El-OP 976 wide-angle HUD and HOTAS system, high performance EltaEL/M-2032ISAR-capable high-resolution SAR/GMTI (ground moving target indicator) multi-mode fire control radar (developed for the IAI Lavi), IAIC mission computer, new navigation equipment including GPS/INS connected to mapping mode, dual MIL-STD-1553B databus managing avionics package, Astronautics Central Air Data Computer, new UHF and IFF packages, airborne video tape recorder (AVTR), Elta EL/L-8222 active ECM pod, Mikes (Aselsan) AN/ALQ-178V3 passive embedded SPEWS, and RWR.[11][13]
These upgraded F-4 Phantoms are referred to as the F-4E-2020 Terminator. 54 were modernized and 30+ of them will be in service until at least 2030.[14] They first entered service on 27 January 2000 with deliveries to 111 and 171 Filo.[15]
Upgraded version of the F-4EJ with improved avionics, including AN/APG-66J pulse-doppler radar, and ground attack capability, including ASM-1 anti-ship missile.

Three Israeli F-4E modified for high-speed reconnaissance as a cheaper alternative to the ambitious F-4X. Fitted with a new nose containing the HIAC-1 LOROP long-range camera with a 66-in (168 cm) focal length as well as a vertical KS-87 camera. The aircraft had a false radome painted on the nose to resemble conventional F-4Es. The fate and service record of these aircraft is unknown.[16]

Re-engined with the more powerful British Rolls-Royce Spey 202 turbofan engines which required an enlarged fuselage but gave more power taking off from smaller carriers and was already in use with Blackburn Buccaneer on RN carriers. Delivered from 1968, with cancellation of planned carriers order cut and 20 diverted to the Royal Air Force before going into service; 50 built. RN aircraft withdrawn by 1978 and passed to RAF.

RF-4M
Proposed, dedicated reconnaissance variant of the F-4M for the RAF; intention to fit equipment internally rather than through carriage of external reconnaissance pod. Not proceeded with.[31]
F-4T
Proposed lightweight air superiority-only fighter version; none built.[32]
Proposed high-performance reconnaissance version with HIAC-1 LOROP camera for Israel developed under the Peace Jack program in conjunction with General Dynamics. Water injection was projected to give the aircraft a top speed in excess of Mach 3 (over 2,000 mph (3,200 km/h) at high altitudes). The water would be contained in a pair of 2,500 US gal (9,600 L) conformal tanks on the sides of the fuselage spine. The US State Department became worried about developing an aircraft with performance similar to the SR-71 Blackbird and offensive capability beyond anything in domestic inventory for a foreign customer and forbade its export. The proposal was then modified to the RF-4X standard with the camera in the nose and removal of weapon carriage. However, the US Air Force withdrew from the project over concerns that a high-performance Phantom would jeopardize funding for the anticipated McDonnell Douglas F-15 Eagle. Without United States financial support, Israel settled for the simpler, less expensive F-4E(S), which was given the nickname 'Shablool', or 'Snail'.[16]
Boeing Super Phantom
A 1984 joint venture between Boeing and Pratt & Whitney for a Phantom variant with Pratt & Whitney PW1120turbofan engines, giving a significant performance gain over J79 Phantoms. The aircraft would also have an 1,100 US gal (4,230 L) conformal fuel tank under the fuselage.[33] Cancelled early in development.[34]
IAI Super Phantom
A separate Israel Aircraft Industries project was proposed for a PW1120-powered Phantom,[35] and one prototype built.[36] IAI's F-4 "Super Phantom" or F-4-2000, which could exceed Mach 1 without afterburners, was displayed at the 1987 Paris Air Show.
