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-126 ECM 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. In 1975, modernized under Project SURE (Sensor Update and Refurbishment Effort); 46 built. Retired in 1990. 4 lost in Vietnam. First flown 12 March 1965.

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-25 RHAWS, 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. Many survivors were reverted to the original F-4C configuration.

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-1 LOROP (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.

Two RF-4Cs shot down by USSR during Project Dark Gene whilst being flown by USAF pilots.
YRF-110A (YRF-4C)
Two prototypes were used in the development of the RF-4C reconnaissance version.

EF-4D Wild Weasel IV
F-4Ds converted into Wild Weasel ECM aircraft. Unlike the EF-4C, the EF-4D had the capability to use the larger AGM-78 Standard ARM.  Only 2 converted.

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
Modernized Israeli F-4Es, AN/APG-76 radar. Contained new avionics, screens, HUD, wiring, digital communication bus. Support for standoff weapons became standard whereas with F-4Es each weapon required different wiring modifications. Entered service in 1989, retired in 2004.
F-4E Peace Icarus 2000 (AUP)

In 1998 the Hellenic Air Force decided, in collaboration with the German Aerospace Industry (DASA) and the Hellenic Aerospace Industry (HAI/EAB), to upgrade 39 F-4E Phantom II fighters. The first aircraft was delivered at Andravida Air Base in December 2002. All upgraded F-4s were equipped with the new AN/APQ-65YG radar similar to that of the F/A-18 Hornet, a new onboard Mission Control Computer (MCC), a Head Up Display, the IFF Interrogator, Multi Function Displays and were also capable of carrying a variety of advanced Air-to-Air and Air-to-Ground missiles. These included the AIM-120 AMRAAM (although only the -B edition), the AIM-9M missile, the AFDS and the entire family of the Paveway (I, II and III) laser-guided bombs. Although gradual retirement of F-4 units started in 2017, a number of aircraft are still operational in multi-role missions with the 338 Squadron ”Ares” and the 339 Squadron "Ajax” based at Andravida Air Base. The F-4E Phantom II PI2000 (AUP) has also been certified for use of GBU-27 Paveway III laser-guided bombs.
F-4E Terminator 2020 

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 20 km of wiring (reducing weight by 750 kg) as well as most hydraulic and pneumatic lines and hoses. 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. 

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 Elta EL/M-2032 ISAR-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.

Additionally, they received AGM-142 Popeye/Have Nap integration, Litening-II targeting pods, and the capability to launch AGM-65D/G Maverick, AGM-88 HARM, GBU-8 HOBOS, GBU-10/12 Paveway II LGBs, general purpose and cluster bombs for air-to-ground missions, while retaining the capability to launch AIM-7 Sparrow and AIM-9 Sidewinder air-to-air missiles. It is also possible to install Pave Spike targeting pods and rocket pods of all sizes.

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. They first entered service on 27 January 2000 with deliveries to 111 and 171 Filo.

Proposals

F4H 
Proposed ground attack variants Model 98DA and Model 98DB for US Army to take off from grass field/forward air base powered by Allison Spey (AR-168), modified from F4H-1; none built.
F-4E(F)
Proposed single-seat simplified version of F-4E for the German Air Force; none built.
F-4L
Proposed AIM-54 Phoenix capable advanced Phantom variant (Model 98FOA) offered to the US Navy in 1963/64 as a replacement for the F-8 Crusader in the fleet defense role The F-4L had an increased wingspan and powered by Allison TF41-A-2 turbofans for quicker acceleration taking off Essex class carriers.
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.
F-4T
Proposed lightweight air superiority-only fighter version; none built.
F-4 (FVS)
Proposed version with airframe modified by Grumman to use variable geometry wings; none built.
F-4X
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'.
Boeing Super Phantom
A 1984 joint venture between Boeing and Pratt & Whitney for a Phantom variant with Pratt & Whitney PW1120 turbofan 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. Cancelled early in development.
IAI Super Phantom
A separate Israel Aircraft Industries project was proposed for a PW1120-powered Phantom, and one prototype built. 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.
