Why is the "Double Ugly" F-4 Phantom II such a beloved airplane?

The F-4 Phantom was neither beautiful nor elegant. But it did its job when many other aircraft of its era could not. Flying Brick, Lead Sled, Rhino, Double Ugly were some of its most common nicknames. Even the official name was ironic - "Phantom" evokes an image of stealth and subtlety, a supernatural enemy that attacks without warning. But the F-4 was anything but stealthy or subtle; it was a great fighter that grew stronger as it fought in battle.

Throughout its service life, it became one of the most influential aircraft in the history of jet fighters. During the tense "Cold War" years of the 1960s and 1970s, the Phantom was the symbol of western world tactical air power. Between 1958 and 1981, 5,195 Phantoms were built in a dozen variants and flown by a dozen countries, making it the most prolific supersonic American fighter aircraft ever built. "The Phantom was arguably one of the most important fighter aircraft of the second half of the twentieth century". 65 years after its first flight, the F-4 is still flying in the Turkish, Greek and South Korean Air Forces.

Both Beautiful and Ugly; that is, "Beauty and the Beast..."

The Phantom is still loved for many things. Beauty is not one of them. Its fat nose gave the F-4 a face only a mother (or aircraft designer) could love. Compared to the sleek F-16 or the gracefully curved F-22, the F-4's up-sloping wing and down-sloping tail look like an improperly assembled model airplane kit. 

To understand the Phantom's story, we need to go back to an era of black and white televisions and room-sized computers. When the Phantom first appeared on the drawing board in 1953, fighter planes had been around for less than a decade.

The F-4 began life as a redesign of McDonnell Aircraft Corp.'s (McDonnell Douglas, which later merged with Boeing) troubled F3H Demon, a carrier-based fighter. The US Navy ordered two Phantom prototypes of the "Super Demon" as an all-weather fighter-bomber.

There was no reason to expect the new aircraft to become a classic; dozens of new fighter and bomber designs emerged in the 1950s. Most would remain prototypes, quickly becoming obsolete or appearing in museum exhibits. But three key moments would shape the Phantom saga.

 In 1955, the US Navy asked McDonnell Aircraft for an interceptor to take off and land from an aircraft carrier to protect the fleet from bombers. While most interceptors are extinct today, they were common in the 1950s, when guided missiles were new and high-altitude manned bombers posed the greatest threat.

 Nations wanted fast jets that could approach high altitudes and intercept bombers before they reached their targets. A powerful radar and newly developed air-to-air guided missiles would also be useful. But there was no need for maneuverability or artillery against clumsy bombers. Or so thought military planners, convinced that dogfights were obsolete and that future air combat would be fought exclusively with missiles.

 At the end of the Vietnam War, the US Department of Defense believed that the Air Force, Navy and Marine Corps Air Forces would save money by using a common fighter/bomber (the same controversial approach would be repeated 40 years later with the F-35). 

The US Department of Defense also insisted on a common name. The new aircraft would be called the F-4 Phantom II, with the Navy and Marine Corps flying the F-4B and the Air Force flying the F-4C.

The Most Powerful Fighter in the Western Bloc

By any measure, the Phantom was a monster compared to its contemporaries. Most fighter/bombers had one seat, but the F-4 had two, with a pilot in the front and a weapons systems officer in the rear. A fully loaded F-4 weighed 28 tons: France's Mirage III weighed 14 tons, while the Soviet MiG-21 weighed only 10 tons. At 63 feet long, the F-4 was 10 feet longer than the other two aircraft.

Still, the Phantom was "muscular, not fat". Its source of power were two General Electric J79 engines, huge for their time, with a thrust capacity of 18,000 pounds each, or 36,000 pounds total, mounted in a sturdy airframe designed to absorb the impact of carrier landings. The Mirage's single engine could only deliver 13,000 pounds of thrust, and the MiG-21 could only deliver 15,000 pounds (though lighter aircraft required less powerful engines). Despite its bulk, the F-4 could fly at Mach 2.2 and reach an altitude of 60,000 feet. Soon after its maiden flight in May 1958, it set 16 world records, including a close-in climb to 98,557 ft in 1959 and a speed of 2,606 miles per hour in 1961. The F-4 Phantom II, which shot down its first MiG-21 in North Vietnam in 1966, was "a great airplane with a lot of power," according to those who flew it.

Size and engine power allowed the Phantom to carry a remarkable payload for its time. The F-4 Phantom II could carry 18,000 pounds of missiles, bombs, external fuel tanks and ECM equipment at nine fixed points under its wings and fuselage (compared to only 10,000 pounds on the Mirage III and only 3,000 pounds on a MiG-21). The F-4 can carry almost the bomb load of a World War II B-29 bomber and quadruple the load of a B-17. For air combat, the Phantom can carry four heat-seeking AIM-9 Sidewinder missiles, plus four AIM-7 Sparrow semi-active radar missiles, which are aimed at targets illuminated by the Phantom's radar.

All this made the Phantom perhaps the most versatile fighter in history. The F-4 was a "true multi-role aircraft" capable of air-to-air combat, air-to-ground combat, Wild Weasel strikes against air defenses that could launch anti-radiation missiles, and reconnaissance sorties.

Phantoms over Vietnam...The legend grows...

The final turning point in the Phantom saga was the Vietnam War, when the F-4 made its real combat debut and cemented its reputation. The Phantom also received a lot of historical criticism for its shortcomings, including poor rear visibility, large turning radius and a tendency to break out of controlled flight during sharp maneuvers. But three flaws in particular stood out: the F-4's engines left highly visible smoke trails, early models lacked an internal cannon for close-in firing at a time when most air-to-air missile launches missed their targets, and instead of long-distance missile duels, the Vietnamese air battles took the form of World War II's "knight's combat in the air" style dogfights. Typical dogfights in which the usually smaller MiG-17, MiG-19 and MiG-21 were more maneuverable and could make short, sharp horizontal turns.

According to the F-4 Air Knights who fought in Vietnam, the F-4s had to "maneuver vertically" in dogfights with these smaller but more maneuverable Russian aircraft. They "could not enter a level turn" with these opponents. These aircraft; "if they could get close to the F-4, they could catch it and shoot at it, because they could turn much tighter".

The F-4's kill ratio against the MiGs was a disappointing 2:1 and sometimes even 1:1. But how much of this was the Phantom's fault? The rules of engagement prohibited US pilots from firing at aircraft without visual identification, and Sparrow shots out of visual range were blocked. North Vietnamese pilots were aided by ground radars that allowed MiGs to set hit-and-run ambushes or catch stray aircraft damaged in battle. In other words, the South Vietnamese used extremely practical but effective tactics against the most capable jet fighter/bomber of its time.

And worst of all, the US suffered from unprepared pilots and inadequate tactics, such as air formations that were too rigid for combat. In Vietnam, the USAF "saw how poorly trained its pilots were and how bad its tactics were". This is what real war is like. You can never underestimate your enemy!...

But the Phantom was not beyond improvement; later models were armed with a 20-millimeter cannon. Pilots learned to exploit the F-4's superior speed by climbing and diving rather than turning (just as American pilots did against the agile Japanese Zero fighters in World War II). In 1972, the US Navy's famous Top Gun training program helped Navy F-4s achieve a 13:1 kill ratio.

The Vietnam air war did not go well for the US air power in proportion to its capacity, in short, it did not go well, making "Double Ugly" a good "scapegoat". Still, the question was not whether the Phantom was flawed. Phantom was flawed in this war. The problem, however, was the inability of the most technologically advanced country to determine its purpose function when designing the most capable jet fighter of its time; the problem was not with McDonnell's aircraft designers, but with the US Air Force's air warfare strategists. Relying on this concept without effectively testing and evaluating the most important air-to-air concept and technology of its time, heat-seeking (AIM-9 Sidewinder) and especially radar-controlled (AIM-7 Sparrow) missiles, and insisting that the Phantom not be fitted with a nose cannon was not an inexplicably blunted vision. 

The biggest threat to US fighter aircraft in Vietnam was not MiGs, but anti-aircraft guns. Ground fire, ranging from radar-controlled anti-aircraft guns to a Vietcong guerrilla firing an AK-47, destroyed most US planes and helicopters that fell to enemy fire. Even as a super dogfighter with a built-in cannon, the F-4 would and did face challenges that would challenge even a modern stealth fighter. The Vietnamese had practically taught the Americans how to use the limited means at their disposal with ingenious skill.

Israel has brought the Phantom/Kurnass into Modern Times...

After America, Israel has the most combat experience with the Phantom. When they acquired the F-4 in 1969, some Israeli pilots reluctantly gave up their energetic little Mirages for the American muscle-bound F-4 (in fact, Israeli pilots were very attached to the Mirage, but they also cared and wanted the Phantom). Still, for a small air force unable to intercept large numbers of fighters/bombers, the multi-role F-4 was invaluable.

Israeli pilots soon took a liking to the Phantom, nicknamed "Kurnass" ("sledgehammer" in Hebrew), and took it to their hearts, even adopting it. Phantom/Kurnass air superiority could perform any mission, including "flying cannon missions" in support of ground troops and even deep penetration strategic bombing. Although the F-4 was primarily assigned to air-to-surface attack missions in the Israeli Air Force, Israeli Phantom fliers achieved 117 aerial kills between 1969 and 1982. This was an astonishing number.

Israeli pilots found that the F-4E version of the Phantom maneuvered very well at low altitudes, they also performed aggressive maneuvers at low altitudes, even breaking the sound barrier at low altitudes, and the modified slats available on this variant contributed greatly to their aerodynamics.

With the F-4E 2020 Kurnass modernization project, Israel modernized its F-4s and used them effectively until they were replaced by F-15s and F-16s.

Subsequently, the Israeli Air Force also became a heavy user of F-16s, and according to the Israeli Air Force, newer 4th Generation fighters like the F-16, while more capable, were less versatile than the F-4. According to them, "there was no task the Phantom couldn't do, if you didn't treat it right it would kick you, but if you treated it right it took a serious interest in you."

In the 1980s, the F-4 was replaced in the USAF by the F-15 and F-16 fighter jets, and only the F-4G Wild Weasel continued in service. In Operation Desert Storm, the F-4G Wild Weasel became a special attack aircraft tasked with the dangerous mission of suppressing and destroying enemy air defenses. The US Air Force finally retired the Phantom from combat altogether in 1996. Nevertheless, it flew the F-4 as the QF-4 air target fighter until 2016.

Turkey, Greece and South Korea still operate some F-4s. Ironically, the largest number of Phantom users today is Iran.

Turkish F-4E Phantom IIs Become 3++ Generation F-4/2020 Terminator 

Turkey has modernized its F-4Es with the best structural integrity with Israeli IAI and Elbit companies to 3++ generation level and dubbed these Phantoms as "Terminators". However, the most preferred nickname of the F-4 in the Turkish Air Force and in Turkey is "Father F-4". The F-4E Terminators modernized by the Turkish Air Force can also carry the AGM-142 Popeyes missile.

Why such intense love for the Phantom? 

The Phantom has many fans around the world today. Why is there such an intense love for this type among the hundreds of jet fighter aircraft types produced since 1945? In our opinion, the main reason for the enduring popularity of the Phantom is the admiration and respect for a strange but brave machine that does its job well. All airplanes look good at the design stage and on their blueprints, and many can even work well under ideal conditions. But real world conditions are rarely ideal, and history is littered with aesthetically pleasing and ideally designed airplanes that failed the test of war. F-4A, B, C, D, E, F, G, K, J The Phantom II is a venerable, a true ghost, a true legend that has passed the test of combat history. Respect to the Phantom, to those who flew with it and to those who supported its flight...
