F-4 Phantom II

The McDonnell Douglas F-4 Phantom II is a two-seat, twin-engined, all-weather, long-range supersonic interceptor fighter/fighter-bomber originally developed for the U.S. Navy by McDonnell Aircraft.




First flown in May 1958, the Phantom II originally was developed for U.S. Navy fleet defense. The U.S. Air Force's first version, the F-4C, made its first flight in May 1963, and production deliveries began six months later. Phantom II production ended in 1979 after over 5,000 had been built -- more than 2,600 for the USAF, about 1,200 for the U.S. Navy and Marine Corps, and the rest for friendly foreign nations

In 1965 the USAF sent its first F-4Cs to Southeast Asia, where they flew air-to-air missions against North Vietnamese fighters as well as attacking ground targets. The first USAF pilot to score four combat victories with F-4s in Southeast Asia was Col. Robin Olds, a World War II ace. The aircraft on display is the one in which Col. Olds, the pilot, and Lt. Stephen Croker, the weapons system officer, destroyed two MiG-17s in a single day, May 20, 1967.


In its air-to-ground role, the F-4C could carry twice the normal load of a WWII B-17. The armament loaded on the aircraft on display is a typical configuration for an F-4C in 1967. It consists of four AIM-7E and four AIM-9B air-to-air missiles, and eight 750-pound Mk 117 bombs. The aircraft also carries two external fuel tanks on the outboard pylons and one ALQ-87 electronic countermeasures (ECM) pod on the right inboard pylon.

The McDonnell Douglas F-4 Phantom II is a two-seat, twin-engined, all-weather, long-range supersonic interceptor fighter/fighter-bomber originally developed for the U.S. Navy by McDonnell Aircraft. Proving highly adaptable, it became a major part of the air wings of the U.S. Navy, U.S. Marine Corps, and U.S. Air Force. It was used extensively by all three of these services during the Vietnam War, serving as the principal air superiority fighter for both the Navy and Air Force, as well as being important in the ground-attack and reconnaissance roles by the close of U.S. involvement in the war.

First entering service in 1960, the Phantom continued to form a major part of U.S. military air power throughout the 1970s and 1980s, being gradually replaced by more modern aircraft such as the F-15 Eagle and F-16 Fighting Falcon in the U.S. Air Force the F-14. Tomcat and F/A-18 Hornet in the U.S. Navy; and the F/A-18 in the U.S. Marine Corps. It remained in use by the U.S. in the reconnaissance and Wild Weasel roles in the 1991 Gulf War, finally leaving service in 1996. The Phantom was also operated by the armed forces of 11 other nations. Israeli Phantoms saw extensive combat in several Arab–Israeli conflicts, while Iran used its large fleet of Phantoms in the Iran–Iraq War. Phantoms remain in front line service with seven countries, and in use as an unmanned target in the U.S. Air Force.

Phantom production ran from 1958 to 1981, with a total of 5,195 built. This extensive run makes it the second most-produced Western jet fighter, behind the F-86 Sabre at just under 10,000 examples.

Overview

The F-4 Phantom was designed as a fleet defense fighter for the U.S. Navy, and first entered service in 1960. By 1963, it had been adopted by the U.S. Air Force for the fighter-bomber role. When production ended in 1981, 5,195 Phantom IIs had been built, making it the most numerous American supersonic military aircraft. Until the advent of the F-15 Eagle, the F-4 also held a record for the longest continuous production for a fighter with a run of 24 years. Innovations in the F-4 included an advanced pulse-doppler radar and extensive use of titanium in its airframe.

Despite the imposing dimensions and a maximum takeoff weight of over 60,000 pounds (27,000 kg), the F-4 had a top speed of Mach 2.23 and an initial climb of over 41,000 ft per minute (210 m/s). Shortly after its introduction, the Phantom set 15 world records, including an absolute speed record of 1,606.342 mph (2,585.086 km/h), and an absolute altitude record of 98,557 ft (30,040 m). Although set in 1959–1962, five of the speed records were not broken until 1975 when the F-15 Eagle came into service.

The F-4 could carry up to 18,650 pounds (8,480 kg) of weapons on nine external hardpoints, including air-to-air and air-to-ground missiles, and unguided, guided, and nuclear bombs. Since the F-8 Crusader was to be used for close combat, the F-4 was designed, like other interceptors of the day, without an internal cannon. In a dogfight, the RIO or WSO (commonly called "backseater" or "pitter") assisted in spotting opposing fighters, visually as well as on radar. It became the primary fighter-bomber of both the Navy and Air Force by the end of the Vietnam War.

Due to its distinctive appearance and widespread service with United States military and its allies, the F-4 is one of the best-known icons of the Cold War. It served in the Vietnam War and Arab–Israeli conflicts, with American F-4 crews claiming 277 aerial victories in Southeast Asia and completing countless ground attack sorties.The Blue Angels flew F-4Js from 1969 to 1974.

The F-4 Phantom has the distinction of being the last United States fighter flown to attain ace status in the 20th century. During the Vietnam War, the USAF had one pilot and two WSOs, and the USN one pilot and one RIO, become aces in air-to-air combat. It was also a capable tactical reconnaissance and Wild Weasel (suppression of enemy air defenses) platform, seeing action as late as 1991, during Operation Desert Storm.
The F-4 Phantom II was also the only aircraft used by both US flight demonstration teams. The USAF Thunderbirds (F-4E) and the USN Blue Angels (F-4J) both switched to the Phantom for the 1969 season; the Thunderbirds flew it for five seasons, the Blue Angels for six.

The baseline performance of a Mach 2-class fighter with long range and a bomber-sized payload would be the template for the next generation of large and light/middle-weight fighters optimized for daylight air combat. The Phantom would be replaced by the F-15 Eagle and F-16 Fighting Falcon in the U.S. Air Force. In the U.S. Navy, it would be replaced by the F-14 Tomcat and the F/A-18 Hornet which revived the concept of a dual-role attack fighter.

Design and development

Origins

In 1952, McDonnell's Chief of Aerodynamics, Dave Lewis, was appointed by CEO Jim McDonnell to be the company’s Preliminary Design Manager. With no new aircraft competitions on the horizon, internal studies concluded the Navy had the greatest need for a new and different aircraft type: an attack fighter.

In 1953, McDonnell Aircraft began work on revising its F3H Demon naval fighter, seeking expanded capabilities and better performance. The company developed several projects including a variant powered by a Wright J67 engine, and variants powered by two Wright J65 engines, or two General Electric J79 engines. The J79-powered version promised a top speed of Mach 1.97. On 19 September 1953, McDonnell approached the United States Navy with a proposal for the "Super Demon". Uniquely, the aircraft was to be modular—it could be fitted with one- or two-seat noses for different missions, with different nose cones to accommodate radar, photo cameras, four 20-millimeter cannon, or 56 FFAR unguided rockets in addition to the nine hardpoints under the wings and the fuselage. The Navy was sufficiently interested to order a full-scale mock-up of the F3H-G/H but felt that the upcoming Grumman XF9F-9 and Vought XF8U-1 already satisfied the need for the supersonic fighter.

The McDonnell design was therefore reworked into an all-weather fighter-bomber with 11 external hardpoints for weapons and on 18 October 1954, the company received a letter of intent for two YAH-1 prototypes. On 26 May 1955, four Navy officers arrived at the McDonnell offices and, within an hour, presented the company with an entirely new set of requirements. Because the Navy already had the A-4 Skyhawk for ground attack and F-8 Crusader for dogfighting, the project now had to fulfill the need for an all-weather fleet defense interceptor. A second crewman was added to operate the powerful radar. XF4H-1 prototype

The XF4H-1 was designed to carry four semi-recessed AAM-N-6 Sparrow III radar-guided missiles, and to be powered by two J79-GE-8 engines. As in the F-101 Voodoo, the engines sat low in the fuselage to maximize internal fuel capacity and ingested air through fixed geometry intakes. The thin-section wing had a leading edge sweep of 45 degrees and was equipped with a boundary layer control system for better low-speed handling.

Wind tunnel testing had revealed lateral instability requiring the addition of five degrees dihedral to the wings.

To avoid redesigning the titanium central section of the aircraft, McDonnell engineers angled up only the outer portions of the wings by 12 degrees which averaged to the required five degrees over the entire wingspan. The wings also received the distinctive "dogtooth" for improved control at high angles of attack. The all-moving tailplane was given 23 degrees of anhedral to improve control at high angles of attack while still keeping the tailplane clear of the engine exhaust. In addition, air intakes were equipped with movable ramps to regulate airflow to the engines at supersonic speeds. All-weather intercept capability was achieved thanks to the AN/APQ-50 radar. To accommodate carrier operations, the landing gear was designed to withstand landings with a sink rate of 23 ft per second (7 m/s), while the nose strut could extend by some 20 inches (50 cm) to increase angle of attack at takeoff.

Naming the aircraft

There were proposals to name the F4H "Satan" and "Mithras", the Persian god of light. In the end, the aircraft was given the less controversial name "Phantom II", the first "Phantom" being another McDonnell jet fighter, the FH-1 Phantom. The Phantom II was briefly given the designation F-110A and the name "Spectre" by the USAF, but neither title was used.

Prototype testing

On 25 July 1955, the Navy ordered two XF4H-1 test aircraft and five YF4H-1 pre-production fighters. The Phantom made its maiden flight on 27 May 1958 with Robert C. Little at the controls. A hydraulic problem precluded retraction of the landing gear but subsequent flights went more smoothly. Early testing resulted in redesign of the air intakes, including the distinctive addition of 12,500 bleed air holes on each ramp; and the aircraft soon squared off against the XF8U-3 Crusader III. Due to operator workload, the Navy wanted a two-seat aircraft and on 17 December 1958 the F4H was declared a winner. Delays with the J79-GE-8 engines meant that the first production aircraft were fitted with J79-GE-2 and -2A engines, each having 16,100 pound-force (71.8 kN) of afterburning thrust. In 1959, the Phantom began carrier suitability trials with the first complete launch-recovery cycle performed on 15 February 1960 from USS Independence.

Production

Early in production, the radar was upgraded to a larger AN/APQ-72, necessitating the bulbous nose, and the canopy was reworked to improve visibility and make the rear cockpit less claustrophobic. The Phantom underwent a great many changes during its career, summarized in the "Variants" section below.
The USAF received Phantoms as the result of Defense Secretary Robert McNamara's push to create a unified fighter for all branches of the military. After an F-4B won the "Operation Highspeed" fly-off against the F-106 Delta Dart, the USAF borrowed two Naval F-4Bs, temporarily designating them F-110A "Spectre" in January 1962, and developed requirements for their own version. Unlike the Navy focus on interception, the USAF emphasized a fighter-bomber role. With McNamara's unification of designations on 18 September 1962, the Phantom became the F-4 with the Naval version designated F-4B and USAF F-4C. The first Air Force Phantom flew on 27 May 1963, exceeding Mach 2 on its maiden flight.

Phantom II production ended in the United States in 1979 after 5,195 had been built (5,057 by McDonnell Douglas and 138 in Japan by Mitsubishi), making it the second-most produced and exported American military-jet; the F-86 Sabre still remains the most numerous jet-powered warplane produced and exported by the United States. Of these, 2,874 went to the USAF, 1,264 to the Navy and Marine Corps, and the rest to foreign customers. The last U.S.-built F-4 went to Turkey, while the last F-4 ever built was completed in 1981 as an F-4EJ by Mitsubishi Heavy Industries in Japan. As of 2001, about 1,100 Phantoms remained in service worldwide, including QF-4 drones operated by the U.S. military.

World records

To show off their new fighter, the Navy led a series of record-breaking flights early in Phantom development:

* Operation Top Flight: On 6 December 1959, the second XF4H-1 performed a zoom climb to a world record 98,557 ft (30,040 m). The previous record of 94,658 ft (28,852 m) was set by a Soviet Sukhoi T-43-1 prototype. Commander Lawrence E. Flint, Jr., USN accelerated his aircraft to Mach 2.5 at 47,000 ft (14,330 m) and climbed to 90,000 ft (27,430 m) at a 45 degree angle. He then shut down the engines and glided to the peak altitude. As the aircraft fell through 70,000 ft (21,300 m), Flint restarted the engines and resumed normal flight.

* On 5 September 1960, an F4H-1 averaged 1,216.78 mph (1,958.16 km/h) over a 500 kilometer (311 mi) closed-circuit course.
* On 25 September 1960, an F4H-1 averaged 1,390.21 mph (2,237.26 km/h) over a 100 kilometer (62 mi) closed-circuit course.

* Operation LANA: To celebrate the 50th anniversary of Naval aviation (L is the Roman numeral for 50 and ANA stood for Anniversary of Naval Aviation) on 24 May 1961, Phantoms flew across the continental United States in under three hours and included several tanker refuelings. The fastest of the aircraft averaged 869.74 mph (1,400.28 km/h) and completed the trip in 2 hours 47 minutes, earning the pilot (and future NASA Astronaut), Lieutenant Richard Gordon, USN and RIO, Lieutenant Bobbie Long, USN, the 1961 Bendix trophy.

* Operation Sageburner: On 28 August 1961, a Phantom averaged 902.769 mph (1,452.826 km/h) over a three-mile (4.82 km) course flying below 125 ft (40 m) at all times. Commander J.L. Felsman, USN was killed during the first attempt at this record on 18 May 1961 when his aircraft disintegrated in the air after pitch damper failure.

* Operation Skyburner: On 22 December 1961, a modified Phantom with water injection set an absolute world record speed of 1,606.342 mph (2,585.086 km/h).

* On 5 December 1961, another Phantom set a sustained altitude record of 66,443.8 ft (20,252.1 m).


* Operation High Jump: A series of time-to-altitude records was set in early 1962; 34.523 seconds to 3,000 m (9,840 ft), 48.787 seconds to 6,000 m (19,680 ft), 61.629 seconds to 9,000 m (29,530 ft), 77.156 seconds to 12,000 m (39,370 ft), 114.548 seconds to 15,000 m (49,210 ft), 178.5 seconds to 20,000 m (65,600 ft), 230.44 seconds to 25,000 m (82,000 ft), and 371.43 seconds to 30,000 m (98,400 ft). Although not officially recognized, the Phantom zoom-climbed to over 100,000 ft (30,480 m) during the last attempt.


All in all, the Phantom set 16 world records. With the exception of Skyburner, all records were achieved in unmodified production aircraft. Five of the speed records remained unbeaten until the F-15 Eagle appeared in 1975.

Flight characteristics

In air combat, the Phantom's greatest advantage was its thrust, which permitted a skilled pilot to engage and disengage from the fight at will. The massive aircraft, designed to fire radar-guided missiles from beyond visual range, lacked the agility of its Soviet opponents and was subject to adverse yaw during hard maneuvering. Although thus subject to irrecoverable spins during aileron rolls, pilots reported the aircraft to be very communicative and easy to fly on the edge of its performance envelope. In 1972, the F-4E model was upgraded with leading edge slats on the wing, greatly improving high-angle-of-attack maneuverability at the expense of top speed.

The J79 engines produced copious amounts of black smoke at military power which made the Phantoms easy to spot from a distance, a severe disadvantage in air combat against smaller aircraft. Pilots could eliminate the smoke by using afterburner, but at the cost of fuel efficiency. Some pilots adopted the procedure of running one engine in dry thrust at normal power setting, and the other in afterburner, resulting in the same total thrust as using both engines at full rated military power without generating the tell-tale smoke trail.

The F-4's biggest weakness, as it was initially designed, was its lack of an internal cannon. For a brief period, doctrine held that turning combat would be impossible at supersonic speeds and little effort was made to teach pilots air combat maneuvering. In reality, engagements quickly became subsonic. Furthermore, the relatively new heat-seeking and radar-guided missiles at the time were frequently reported as unreliable and pilots had to use multiple shots just to hit one target. To compound the problem, rules of engagement in Vietnam precluded long-range missile attacks in most instances, as visual identification was normally required.

Many pilots found themselves on the tail of an enemy aircraft but too close to fire short-range Falcons or Sidewinders. Although in 1967 USAF F-4Cs began carrying SUU-16 or SUU-23 external gunpods containing a 20 millimeter M61 Vulcan Gatling cannon, USAF cockpits were not equipped with lead-computing gunsights, virtually assuring a miss in a maneuvering fight. Some Marine Corps aircraft carried two pods for strafing. In addition to the loss of performance due to drag, combat showed the externally mounted cannon to be inaccurate unless frequently boresighted, yet far more cost-effective than missiles. The lack of cannon was finally addressed by adding an internally mounted 20 millimeter M61 Vulcan on the F-4E.

Operational history

United States Navy

On 30 December 1960, the VF-121 Pacemakers at NAS Miramar became the first Phantom operator with its F4H-1Fs (F-4As). The VF-74 Be-devilers at NAS Oceana became the first deployable Phantom squadron when it received its F4H-1s (F-4Bs) on 8 July 1961. The squadron completed carrier qualifications in October 1961 and Phantom’s first full carrier deployment between August 1962 and March 1963 aboard USS Forrestal (CV-59)Template:WP Ships USS instances. The second deployable US Atlantic Fleet squadron to receive F-4Bs was the VF-102 Diamondbacks, who promptly took their new aircraft on the shakedown cruise of USS Enterprise. The first deployable US Pacific Fleet squadron to receive the F-4B was the VF-114 Aardvarks, which participated in the September 1962 cruise aboard USS Kitty Hawk.

By the time of the Tonkin Gulf incident, 13 of 31 deployable Navy squadrons were armed with the type. F-4Bs from USS Constellation made the first Phantom combat sortie of the Vietnam War on 5 August 1964, flying bomber escort in Operation Pierce Arrow. The first Phantom air-to-air victory of the war took place on 9 April 1965 when an F-4B from VF-96 Fighting Falcons piloted by Lieutenant (junior grade) Terence M.

Murphy and his RIO, Ensign Ronald Fegan, shot down a Chinese MiG-17 'Fresco'. The Phantom was then shot down, apparently by an AIM-7 Sparrow from one of its wingmen. There continues to be controversy over whether the Phantom was shot down by MiG guns or whether, as enemy reports later indicated, an AIM-7 Sparrow III from one of Murphy's and Fegan's wingmen. On 17 June 1965, an F-4B from VF-21 Freelancers piloted by Commander Thomas C. Page and Lieutenant John C. Smith shot down the first North Vietnamese MiG of the war.

On 10 May 1972, Lieutenant Randy "Duke" Cunningham and Lieutenant (junior grade) William P. Driscoll flying an F-4J, call sign "Showtime 100", shot down three MiG-17s to become the first flying aces of the war. Their fifth victory was believed at the time to be over a mysterious North Vietnamese ace, Colonel Toon, now considered mythical. On the return flight, the Phantom was damaged by an enemy surface-to-air missile. To avoid being captured, Cunningham and Driscoll flew their burning aircraft upside down (the damage made the aircraft uncontrollable in a conventional attitude) until they could eject over water. Cunningham and Driscoll became USN aces by shooting down five or more enemy aircraft.

During the war, Navy Phantom squadrons participated in 84 combat tours with F-4Bs, F-4Js, and F-4Ns. The Navy claimed 40 air-to-air victories at the cost of 71 Phantoms lost in combat (5 to aircraft, 13 to SAMs, and 53 to AAA). An additional 54 Phantoms were lost in accidents. Of the 40 aircraft shot down by Navy and Marine Phantom crews, 22 were MiG-17s, 14 MiG-21s, two Antonov An-2s, and two MiG-19s. Of these, eight aircraft were downed by AIM-7 Sparrow missiles and 31 by AIM-9 Sidewinders.

By 1983, the F-4Ns had been completely replaced by F-14 Tomcats, and by 1986 the last F-4Ss were exchanged for F/A-18 Hornets. On 25 March 1986, an F-4S belonging to VF-151 Vigilantes became the last Navy Phantom to launch from an aircraft carrier, in this case, the USS Midway. On 18 October 1986, an F-4S from the VF-202 Superheats, a Naval Reserve fighter squadron, made the last-ever Phantom carrier landing while operating aboard USS America. In 1987, the last of the Naval Reserve-operated F-4Ss were replaced by F-14As. The last Phantoms in service with the Navy were QF-4 target drones operated by the Naval Air Warfare Centers. These were retired in 2004.

United States Marine Corps

The Marines received their first F-4Bs in June 1962, with the Black Knights of VMFA-314 at Marine Corps Air Station El Toro, California becoming the first operational squadron. In addition to attack variants, the Marines also operated several tactical reconnaissance RF-4Bs. Marine Phantoms from VMFA-531 arrived in Vietnam on 10 April 1965, flying close air support missions from land bases as well as from USS America. Marine F-4 pilots claimed three enemy MiGs (two while on exchange duty with the USAF) at the cost of 75 aircraft lost in combat, mostly to ground fire, and four in accidents. On 18 January 1992, the last Marine Phantom, an F-4S, was retired by the Cowboys of VMFA-112. The squadron was re-equipped with F/A-18 Hornets.

United States Air Force

In USAF service the F-4 was initially designated the F-110 Spectre prior to the introduction of the 1962 United States Tri-Service aircraft designation system. At first reluctant to adopt a Navy fighter, the USAF quickly embraced the design and became the largest Phantom user. The first Air Force Phantoms in Vietnam were F-4Cs from the 555th "Triple Nickel" Tactical Fighter Squadron, which arrived in December 1964.

Unlike the Navy, which flew the Phantom with a Naval Aviator (pilot) in the front seat and a Naval Flight Officer as a radar intercept officer (RIO) in the back seat, the Air Force initially flew its Phantoms with a rated pilot in the back seat. This policy was later changed to using a navigator qualified as a weapon/targeting systems officer (later designated as weapon systems officer or WSO) in the rear seat. However, because they originally flew with pilots in the rear seat, all USAF Phantoms retained dual flight controls throughout their service life.

USAF F-4Cs scored their first victories against North Vietnamese MiG-17s on 10 July 1965 using AIM-9 Sidewinder air-to-air missiles. On 24 July 1965, a Phantom from the 47th Tactical Fighter Squadron on temporary assignment in Vietnam became the first American aircraft to be downed by an enemy SAM, and on 5 October 1966 an 8th Tactical Fighter Wing F-4C became the first U.S. jet lost to an air-to-air missile, fired by a MiG-21 "Fishbed".

Early aircraft suffered from leaks in wing fuel tanks that required re-sealing after each flight and 85 aircraft were found to have cracks in outer wing ribs and stringers. There were also problems with aileron control cylinders, electrical connectors, and engine compartment fires. Reconnaissance RF-4Cs made their debut in Vietnam on 30 October 1965, flying the hazardous post-strike reconnaissance missions.

Although the F-4C was essentially identical to the Navy F-4B in flight performance and carried the Navy-designed Sidewinder missiles, USAF-tailored F-4Ds initially arrived in June 1967 equipped with AIM-4 Falcons. However, the Falcon, like its predecessors, was designed to shoot down bombers flying straight and level. Its reliability proved no better than others, and its complex firing sequence and limited seeker-head cooling time made it virtually useless in combat against agile fighters. The F-4Ds reverted to using Sidewinders under the "Rivet Haste" program in early 1968, and by 1972, the AIM-7E-2 "Dogfight Sparrow" had become the preferred missile for USAF pilots. Like other Vietnam War Phantoms, the F-4Ds were urgently fitted with radar homing and warning (RHAW) antennae to detect the Soviet-built SA-2 Guideline SAMs.

From the initial deployment of the F-4C to Southeast Asia, USAF Phantoms performed both air superiority and ground attack roles, supporting not only ground troops in South Vietnam but also conducting bombing sorties in Laos and North Vietnam. As the F-105 force underwent severe attrition between 1965 and 1968, the bombing role of the F-4 proportionately increased until after November 1970 (when the last F-105D was withdrawn from combat) it became the primary USAF ordnance delivery system. In October 1972 the first squadron of EF-4C Wild Weasel aircraft deployed to Thailand on temporary duty. The "E" prefix was later dropped and the aircraft were simply known as F-4C Wild Weasels.

Sixteen squadrons of Phantoms were permanently deployed between 1965 and 1973, and 17 others deployed on temporary combat assignments. Peak numbers of combat F-4s occurred in 1972, when 353 were based in Thailand. A total of 445 Air Force Phantom fighter-bombers were lost, 370 in combat and 193 of those over North Vietnam (33 to MiGs, 30 to SAMs, and 307 to AAA).

The RF-4C was operated by four squadrons, and of the 83 losses, 72 were in combat including 38 over North Vietnam (seven to SAMs and 65 to AAA). By war's end the U.S. Air Force had lost a total of 528 F-4 and RF-4C Phantoms. When combined with US Naval/Marine losses of 233 Phantoms; 761 F-4/RF-4 Phantoms were lost in the Vietnam War.

On 28 August 1972, Capt Steve Ritchie became the first USAF ace of the war. On 9 September 1972, WSO Capt Charles B. DeBellevue became the highest-scoring American ace of the war with six victories.

And WSO Capt Jeffrey Feinstein became the last USAF ace of the war on 13 October 1972. Upon return to the United States, DeBellevue and Feinstein were given vision waivers, assigned to pilot training and requalified as USAF pilots in the F-4. According to the USAF, its F-4s scored 107½ MiG kills in Southeast Asia (50 by Sparrow, 31 by Sidewinder, five by Falcon, 15.5 by gun, and six by other means).

On 31 January 1972, the 170th Tactical Fighter Squadron/183d Tactical Fighter Group of the Illinois Air National Guard became the first Air National Guard unit to transition to Phantoms. The Phantom's ANG service lasted until 31 March 1990, when it was replaced by the F-16 Fighting Falcon.

On 15 August 1990, 24 F-4G Wild Weasel Vs and six RF-4Cs were mobilized to the Middle East for Operation Desert Storm. The reason for this was that the F-4G was the only aircraft in the USAF inventory equipped for the suppression of enemy air defenses (SEAD) role since the EF-111 Raven lacked the offensive capability of the AGM-88 HARM missile, while the RF-4C was the only aircraft equipped with the ultra-long-range KS-127 LOROP (long-range oblique photography) camera. In spite of flying almost daily missions, only one RF-4C was lost in a fatal accident before the start of hostilities. One F-4G was lost when enemy fire damaged the fuel tanks and the aircraft ran out of fuel near a friendly airbase. The last USAF Phantoms, F-4G Wild Weasel Vs from 561st Fighter Squadron, were retired on 26 March 1996. The last operational flight of the F-4G Wild Weasel was from the 190th Fighter Squadron, Idaho Air National Guard, in April 1996. The last operational USAF/ANG F-4 to land was flown by Maj Mike Webb and Maj Gary Leeder, Idaho ANG. Like the Navy, the Air Force continues to operate QF-4 target drones, serving with the 82d Aerial Targets Squadron, it being expected that the F-4 will remain in the target role with the 82d ATRS until 2013/14.

Non-U.S. air forces

The Phantom served with the air forces of many countries, including Australia, Egypt, Germany, United Kingdom, Greece, Iran, Israel, Japan, Spain, South Korea and Turkey.

Australia

The Royal Australian Air Force (RAAF) leased 24 USAF F-4Es from 1970 to 1973 while waiting for their order for the General Dynamics F-111C to be delivered. They were so well-liked that the RAAF considered adopting the F-4E instead. They were operated from RAAF Amberley by No.1 Squadron and No.6 Squadron.

Egypt

In 1979, the Egyptian Air Force purchased 35 former USAF F-4Es along with a number of Sparrow, Sidewinder, and Maverick missiles from the US for $594 million as part of the "Peace Pharaoh" program. An additional seven surplus USAF aircraft were purchased in 1988. Three attrition replacements had been received by the end of the 1990s.

Germany

The German Luftwaffe initially ordered the reconnaissance RF-4E in 1969, receiving a total of 88 aircraft which were delivered from January 1971. In 1982, the initially unarmed RF-4Es were given a secondary ground attack capability, and were retired in 1994.

In 1973, under the "Peace Rhine" program the Luftwaffe purchased the lightened and simplified F-4F which was upgraded in the mid-1980s. Twenty-four German-owned F-4Fs were operated by the 49th Tactical Fighter Wing of the USAF at Holloman AFB to train Luftwaffe crews until 2002. In 1975, Germany also received 10 F-4Es for training in the U.S. In the late 1990s, these were withdrawn from service, being replaced by F-4Fs. Germany also initiated the "ICE" (Improved Combat Efficiency) program in 1983. The 110 ICE-upgraded F-4Fs entered service in 1992, and are expected to remain in service until 2012.

Greece

In 1971 the Hellenic Air Force ordered brand new F-4E Phantoms, with deliveries starting in 1974. Later (early 1990s) the Hellenic AF acquired surplus RF-4Es and F-4Es from the Luftwaffe and U.S. ANG.
Following the success of the German ICE program, on 11 August 1997, DASA of Germany received a contract to upgrade 39 aircraft to the very similar "Peace Icarus 2000" standard. As of May 2008 the Hellenic AF operates 35 upgraded F-4E-PI2000 (338 and 339 Squadrons) and 22 RF-4E aircraft (348 Squadron).

Iran

In the 1960s and 1970s, then U.S.-friendly Iran purchased 225 F-4D, F-4E and RF-4E Phantoms. The Islamic Republic of Iran Air Force Phantoms saw action in the Iran-Iraq war in the 1980s and are kept operational by overhaul and servicing from Iran’s aerospace industry.

Israel

The Israeli Air Force has been the largest foreign user of the Phantom, flying both newly built and ex-USAF aircraft, as well as several one-off special reconnaissance variants. The first F-4Es, nicknamed "Kurnass" (Heavy hammer), and RF-4Es, nicknamed "Orev" (Raven), were delivered in 1969 under the "Peace Echo I" program. Additional Phantoms arrived during the 1970s under "Peace Echo II" through "Peace Echo V" and "Nickel Grass" programs. Israeli Phantoms saw extensive combat during Arab–Israeli conflicts, first seeing action during the War of Attrition. In the 1980s, Israel began the "Kurnass 2000" modernization program which significantly updated avionics. The last Israeli F-4s were retired in 2004.

Japan

From 1968, the Japan Air Self-Defense Force purchased a total of 140 F-4EJ Phantoms without aerial refueling and ground attack capabilities. Mitsubishi built 138 under license in Japan and 14 unarmed reconnaissance RF-4Es were imported. Of these, 96 F-4EJs have since been modified to the F-4EJ Kai ("modified") standard. Fifteen F-4EJs have been converted to reconnaissance aircraft designated RF-4EJ, with similar upgrades as the F-4EJ Kai. As of 2007, Japan has a fleet of 90 F-4s in service and studies are underway to replace them with either the Eurofighter Typhoon, Dassault Rafale, or one of several others.

South Korea

The Republic of Korea Air Force purchased its first batch of ex-USAF F-4D Phantoms in 1968 under the "Peace Spectator" program. The ex-USAF F-4Ds continued to be delivered until 1988. The "Peace Pheasant II" program also provided newly-built and ex-USAF F-4Es. Currently F-4Ds are being retired from service by new F-15K Slam Eagles.

Spain

The Spanish Air Force acquired its first batch of ex-USAF F-4C Phantoms in 1971 under the "Peace Alfa" program. Designated C.12, the aircraft were retired in 1989. At the same time, the SAF received a number of ex-USAF RF-4Cs, designated CR.12. In 1995–1996, these aircraft received extensive avionics upgrades. Spain retired its RF-4s in 2002.

Turkey

The Turkish Air Force received 40 F-4Es in 1974, with a further 32 F-4Es and 8 RF-4Es in 1977-78 under the "Peace Diamond III" program, followed by 40 ex-USAF aircraft in "Peace Diamond IV" in 1987, and a further 40 ex-U.S. Air National Guard Aircraft in 1991. A further 32 RF-4Es were transferred to Turkey after being retired by the Luftwaffe between 1992 and 1994. In 1995, IAI of Israel implemented an upgrade similar to Kurnass 2000 on 54 Turkish F-4Es which were dubbed the F-4E 2020 Terminator.

United Kingdom

The United Kingdom bought versions based on the USN F-4J for use with the Royal Air Force and the Royal Navy's Fleet Air Arm. The main differences were the use of the British Rolls-Royce Spey engines and of British-made avionics. The RN and RAF versions were given the designation F-4K and F-4M respectively, and entered service as the Phantom FG.1 (fighter/ground attack) and Phantom FGR.2 (fighter/ground attack/reconnaissance).

After the Falklands War, 15 upgraded ex-USN F-4Js, known as the F-4J(UK) entered RAF service to compensate for one interceptor squadron redeployed to the Falklands.

Around 15 RAF squadrons received various marks of Phantom, many of them based in Germany. The first to be equipped was 6 Squadron at RAF Leuchars in July 1969. One noteworthy deployment was to 43 Squadron where Phantom FG1s remained the squadron equipment for a remarkable twenty years, arriving in September 1969 and departing in July 1989. During this period the squadron was based throughout at Leuchars.

The interceptor Phantoms were replaced by the Panavia Tornado F3 from the late 1980s onwards, and the last British Phantoms were retired in October 1992 when 74 Squadron disbanded.

Civilian use

Sandia National Laboratories used an F-4 mounted on a "rocket sled" in a crash test to see the results of an aircraft hitting a reinforced concrete structure, such as a nuclear power plant.
One aircraft, an F-4D (civilian registration NX749CF), is operated by the Massachusetts-based non-profit organization Collings Foundation as a "living history" exhibit. Funds to maintain and operate the aircraft, which is based in Houston, Texas, are raised through donations/sponsorships from public and commercial parties.

NASA's Dryden Flight Research Center acquired an F-4A Phantom II on 3 December 1965. It made fifty-five flights in support of short programs, chase on X-15 missions and lifting body flights. The F-4A also supported a biomedical monitoring program involving 1,000 flights by NASA Flight Research Center aerospace research pilots and students of the USAF Aerospace Research Pilot School flying high-performance aircraft. The pilots were instrumented to record accurate and reliable data of electrocardiogram, respiration rate and normal acceleration. In 1967, the F-4A supported a brief military-inspired program to determine whether an airplane's sonic boom could be directed and whether it could possibly be used as a weapon of sorts, or at least an annoyance. NASA also flew an F-4C in a spanwise blowing study from 1983 to 1985, after which it was returned to the Air Force.
