The Third Generation Fighter aircraft arrived with a limited supersonic capability and a missile-centric war load before eventually evolving to become more multi-role solutions in their over-battlfield purpose. With many air forces using their second gen fighters in roles beyond aerial superiority, third generation fighters were designed for multirole capabilities. How could the F-4 possibly keep up in this new environment? The North Vietnamese MiGs, equipped with both cannons and missiles (on the MiG-21), would outmaneuver the heavier F-4, which for all its speed, was not especially agile. The McDonnell Douglas F-4 Phantom II is a legendary aircraftan icon of the Vietnam War and the archetype of the third-generation jet fighter designs that entered service in the 1960s. 3rd Generation Jet Fighters Quiz Information. Other famous third generation fighters include the Dassault Mirage F1, Hawker Siddeley Harrier, and MiG-23. So they began searching for another way to power their aircraft: jet propulsion. These formed the backbone of the Iranian fighter force during the nine-year-long war with Iraq. Active Doppler radars cut through the ground clutter. Worse, American pilots werent trained for close range dogfights, as the Air Force assumed air-to-air engagements would occur at long range with missiles. The F-4E model finally came with an internal M161 Vulcan cannon. Third-generation fighters were often designed primarily as interceptors, being built around speed and air-to-air missiles. Developments in fighter jet technology included making them faster, more maneuverable and extending their range and payload capabilities among others. When the F-15 and the lighter F-16 saw their first major air action over Lebanon in 1982, they shot down more than 80 Syrian third-generation MiGs at no loss. [citation needed]) They had little or no avionics, with their primary armament being manually-controlled guns. A squadron of Chinese J-7 fighter jets in 1999. J-7s, copies of the Soviet MiG-21, were . [19] Chinese People's Liberation Army (PLA), with a different generation system, classifies most fourth-generation fighters as the third generation. Please direct all other inquiries to militaryfactory AT gmail.com. But the Phantoms record in air-to-air combat over Vietnamespecially when compared to its successor, the F-15 Eagle, which has never been shot down in air-to-air combathas left it with a reputation of being a clumsy bruiser reliant on brute engine power and obsolete weapons technology. Just two Phantoms managed to scramble in defense, but they shot down seven of the attackers. Iran received 225 F-4s from the United States prior to the Iranian Revolution. The Panavia Tornado remained multi-role and developed a defensive/offensive sensor, avionics and weapons suite especially capable of anti-radar and anti-missile ground attack, while the Lockheed F-117 introduced stealth as a design concept. [2] Other schemes comprising five generations up to around the same period have since been described, although the demarcation lines between generations differ. This aircraft has an upward opening canopy, which is hinged at the rear. These are a few of the preferred methods employed in some fifth-generation fighters to reduce RCS.[25][26]. The 3rd Generation Fighter crop was headlined by such classic types as the American Century series and Soviet MiG-17 and MiG-21 types. Other famous third generation fighters include the Dassault Mirage F1, Hawker Siddeley Harrier, and MiG-23 . The F-5F is a dual-seat version, twin-engine, tactical fighter commonly used for training and adversary combat tactics. In some cases, such as the Mikoyan-Gurevich MiG-35 developed from the MiG-29 with fifth-generation avionics, the upgrade has been classed as fully fifth generation. But surely the electronics and instruments are out of date? Key point:The F-4 served for a long time and even now serve as target practice drones. For instance, modernized F-4s have improved Heads Up Displays (HUDs) so that pilots dont have to look down from the canopy to check on their instruments. South Korea still has 71 F-4Es (only modestly upgraded) in its 17th Fighter Wing. China's new multi-role fighter jet J-10C began combat duty Monday, the People's Liberation Army (PLA) air force announced. Third-generation aircraft arrived in the early 1960s. It was now possible to combine the C3, fighter and ground support roles in a single, agile aircraft. Israeli upgrades contributed to the Turkish air forces Terminator 2020, which has additional wing strakes for improved maneuverability. This aircraft carries AIM-9 Sidewinder missiles on wingtip launchers. Combined with a thrust-to-weight ratio above unity, this enabled it to maintain near-zero airspeed at high angles of attack without stalling, and perform novel aerobatics such as Pugachev's Cobra. The Turkish versions also feature a diverse array of modern sensors and electronics. KAI KF-21 Boramae is a purpose-built joint South Korean/Indonesian 4.5-generation fighter program. Fourth-generation designs are heavily influenced by lessons learned from the previous generation of combat aircraft. The sharing of targeting and sensor data allows pilots to put radiating, highly visible sensors further from enemy forces, while using those data to vector silent fighters toward the enemy. [1][13], The rest of this article broadly follows the analysis of Baker.[1]. Air-to-air missile technology dramatically improved with later versions of the Sparrow and Sidewinder. The F-5 was developed by Northrop Grumman for export through the Military Assistance Program (MAP) in February 1965. Aircraft like the F-4 Phantom could carry a variety of air-to-air and air-to-ground weapons, including the first laser-guided smart-bombs. The primary sensor for all modern fighters is radar. For instance, modernized F-4s have improved Heads Up Displays (HUDs) so that pilots dont have to look down from the canopy to check on their instruments. Among the most famous fourth gen fighters are the Saab Viggen, F-16, Panavia Tornado, Su-27 and Harrier II. This will make the 3rd generation fighters vulnerable and unarmed, which reignites the flexibility of the 4th generation fighters. The ambitious project sought to create a versatile common fighter for many roles and services. In contrast, a preceding fourth generation filled in the gap since the F-15/16 era. Alternatively, 4.5 generation fighters are also called 4+ generation fighters. [14][20], Later variants of these and other aircraft progressively enhanced their characteristic technologies and increasingly incorporated aspects of each other's, as well as adopting some emerging fifth-generation technologies such as:[21]. 9/10 Lockheed F-104 Starfighter (Mach 2) Maintaining supersonic speed without afterburner use saves large quantities of fuel, greatly increasing range and endurance, but the engine power available is limited and drag rises sharply in the transonic region, so drag-creating equipment such as external stores and their attachment points must be minimised, preferably with the use of internal storage. These aging aircraft will be replaced by low-houred F-5N/F acquired from the Swiss Air Force surplus by United States Navy (USN). (The Me 262 had a lightly swept wing, but this was done principally to achieve balance, and the sweep was deliberately kept too little to have a significant aerodynamic effect. The F-5N/Fs are third-generation F-5 fighter aircraft designed for replacement of the F-5A/B/E production models. With variable-geometry wings, the supersonic F-111 introduced the Pratt & Whitney TF30, the first turbofan equipped with afterburner. The first fixed-wing type to display enhanced manoeuvrability in this way was the Sukhoi Su-27, the first aircraft to publicly display thrust vectoring in pitch. Two sub-variants of the Phantom also distinguished themselvesthe RF-4 photo reconnaissance plane, optimized for speed, and the Wild Weasel, specialized in attacking enemy surface-to-air missiles defenses. Sophisticated automation and human interfaces could greatly reduce crew workload. The Eurofighter Typhoon can cruise around Mach 1.2 without afterburner, with the maximum level speed without reheat is Mach 1.5. The supremacy of the fourth-generation was confirmed again in the Gulf War, in which Iraqi fighters shot down only one fourth-generation fighter (an F/A-18 Hornet) for the loss of 33 of their third-generation aircraft. New J79 engines even dealt with the problem of the F-4s visible black smoke. Before, some Phantom units made do with external gun pods that vibrated excessively. As speed was now the aim of the game, engineers made every effort to incorporate then-cutting edge aerodynamic advances such as swept wings (or in some cases, blended wings!) ", "HAL Tejas, the strongest fighter plane of its generation, developed indigenously by India. For example, the F-15C Eagle, first produced in 1978, has received upgrades in 2007 such as AESA radar and joint helmet-mounted cueing system, and is scheduled to receive a 2040C upgrade to keep it in service until 2040. However, the F-4s problems began to recede. Guns proved unsuitable at such high speeds, while the need for multirole capability in battlefield support was rediscovered.

Phil Handley shot down a MiG-19 with his planes gunthe only recorded aerial gun kill performed at supersonic speed. ", "Characterization of Radar Cross Section of Carbon Fiber Composite Materials", "Lockheed-Martin F-35 Joint Strike Fighter Analysis 2002. There is a printable worksheet available for download here so you can take the quiz with pen and paper. The concept of a third generation fighter is perhaps best exemplified by the F-4 Phantom, an aircraft synonymous with the Vietnam War. Dogfights forced improvements in manoeuvrability, air-to-air missiles and radar systems. During the 1970s, early stealth technology led to the faceted airframe of the Lockheed F-117 Nighthawk ground-attack aircraft. Indeed, fourth gen fighters are among the fastest aircraft ever built even faster than their fifth gen counterparts. Theyve bombed Kurdish PKK fighters in Turkey and Iraq in 2015 and 2016. The Korean War of 1950-1953 forced a major rethink. But aerial warfare didnt truly become widespread until WWI, leading to the first so-called fighter aircraft, like the Fokker Eindecker and Sopwith Camel, which were specifically designed for aerial combat. Key Point:The Phantom has proven both versatile and adaptable over time. The Air Forces Phantoms claimed 107 air-to-air kills for 33 lost to MiGs, and the Marine Corps claimed three. As combat aircraft are essentially weapons platforms, these capabilities mean that the F-4s can handle most of the same offensive tasks a fourth-generation F-15 or Su-27 fighter can do. On the other hand, the rules-of-engagement over Vietnam prohibited U.S. pilots from shooting at unidentified targets beyond visual range, further crippling the advantages of the missiles. Navy pilots went on to score a superior kill ratio over Vietnam of 40 victories for seven planes lost in air-to-air combat. Baker 2018, Chapter 3: Generation Rising. In some respects, yes, if you discount the fact the J-8 stemmed from a modernization of the MiG-21F. Their wide-scale use revealed the immense shortfalls of first gen fighters; theyd advanced so much but still had a long way to go. This era also saw an expansion in ground-attack capabilities, principally in guided missiles, and witnessed the introduction of the first truly effective avionics for enhanced ground attack, including terrain-avoidance systems. To improve accuracy of these, second generation fighters were fitted with rudimentary avionics, including a supersonic radar. The earliest jet fighters appeared during and after the last years of World War II. Third-generation fighters were often designed primarily as interceptors, being built around speed and air-to-air missiles. For the next-generation F-22 and F-35, the U.S. will use low probability of intercept capacity. Combining many of the developments originally designed for fifth generation fighters with the technology on already-proven fourth generation fighters, 4.5 gen fighters arent distinct enough to be their own separate generation but are unique enough to not fit into the classification of either fourth or fifth generation fighters. It also led to the development of new automatic-fire weapons, primarily chain-guns that use an electric motor to drive the mechanism of a cannon; this allowed a single multi-barrel weapon (such as the 20mm Vulcan) to be carried and provided greater rates of fire and accuracy. This is a detailed video on 3nd Generation Jet Fighter, Evolution Of Jet Fighters. Late to the party, the J-8B was a third gen fighter while the competition had moved on. Japan maintains the same number of F-4EJ Kais upgraded with pulse-Doppler radars and anti-ship missiles. - Thecompares.net", "With the J20 stealth fighter in fully operation service, China leaps ahead in Asian arms race", "China racing for 6th-gen fighter edge over US", "China Is Working On Its Own Sixth-Generation Fighter Program: Official", "The First Sixth-Generation Aircraft Ever, the B-21 Raider Is "a Bomber Like No Other", https://en.wikipedia.org/w/index.php?title=Jet_fighter_generations&oldid=1142322843, Early supersonic, radar, air-to-air missiles, Supersonic (limited purpose), Mach 2 air-to-air missiles only, Supersonic multirole, high efficiency, high maneuverability, Enhanced capabilities, advanced avionics, limited stealth, Advanced integrated avionics, low observable stealth, This page was last edited on 1 March 2023, at 19:39. carbon-fiber composite in manufacturing. The Phantoms flown by the Turkish and Greek air forces both have modern pulse-doppler radars, which give the F-4 look down-shoot down capabilities. For the purposes of this article, we will be using the most widely used and accepted consensus regarding which aircraft are in which generation and the notion of five generations over four. So far, almost every aspect of 21st century life has been defined by increased digitization. The list does not include projects that were cancelled before an aircraft was built or fictional aircraft. Just compare it to F-15 Eagle. The Air Force didnt realize those early missiles were terrible. These aircraft placed an emphasis on a multi-role capability. Air-to-air missile technology dramatically improved with later versions of the Sparrow and Sidewinder. A few famous (or should I say infamous?) The F-15, which entered service in 1975, is emblematic of fourth-generation fighter aircraft that remain the mainstay of modern air forces today. An unstable aircraft can therefore be made more maneuverable. The Falcon missiles were even worse, and the Pentagon later withdrew them from service. Propulsion: (2) J85-GE-21C turbojet engines each producing 5,000 pounds (2,273 kg) of thrust. However, positive static stability, the tendency to remain in its current attitude, opposes the pilot's efforts to maneuver. Aronstein, David C. and Albert C. Piccirillo. As the war progressed, so did the sophistication of fighter aircraft. Almost all avionics on these aircraft are digital, with the aircraft being programmed through millions of lines of code. The weapons officer in the rear-seat could operate the planes advanced radar, communication and weapons systems while the pilot focused on flying. The third generation witnessed continued maturation of second-generation innovations, but it is most marked by renewed emphases on manoeuvrability and traditional ground-attack capabilities. This will spread the energy of a radar pulse over several frequencies, so as not to trip the radar warning receivers that all aircraft carry. While the basic principles of shaping aircraft to avoid radar detection were known since the 1960s, the advent of radar-absorbent materials allowed aircraft of drastically reduced radar cross-section to become practicable. The only other frontline fighter to serve in all three services before or since is the F-35. In some respects, yes, if you discount the fact the J-8 stemmed from a modernization of the MiG-21F. [16] Notable types which took part in the Korean War of 1950-53 include the Soviet Mikoyan-Gurevich MiG-15 and the North American F-86 Sabre. Aside from being powered by a jet powerplant, rather than a piston one, these first generation fighters were little different to their contemporaries, featuring minor sweep or unswept wings, manually controlled guns and little in the way of modern avionics. Replacement of analog avionics, required to enable FBW operations, became a fundamental requirement as legacy analog computer systems began to be replaced by digital flight-control systems in the latter half of the 1980s. (Recommended: 5 Greatest Fighter Planes of All-Time). [18], Following the mixed successes of the multirole generation, advanced technologies were being developed, such as fly-by-wire, composite materials, thrust-to-weight ratios greater than unity, hypermaneuverability, advanced digital avionics and sensors such as synthetic radar and infrared search-and-track, and stealth. This technique, called RSS, was incorporated to further enhance the aircraft's performance. Subsequent types include the Lockheed Martin F-35, Chengdu J-20,[24] and Sukhoi Su-57. All developed and/or introduced in between 1960-1975. Furthermore, the Phantoms J79 engines produced thick black smoke, which combined with the aircrafts larger size, made it easier to spot and target from a distance. The McDonnell Douglas F-4 Phantom II is a legendary aircraft an icon of the Vietnam War and the archetype of the third-generation jet fighter designs that entered service in the 1960s. Jet fighter generations classify the major technology leaps in the historical development of the jet fighter. While guns remained standard equipment (early models of F-4 being a notable exception), air-to-air missiles became the primary weapons for air superiority fighters, which employed more sophisticated radars and medium-range RF AAMs to achieve greater "stand-off" ranges, however, kill probabilities proved unexpectedly low for RF missiles due to poor reliability and improved electronic countermeasures (ECM) for spoofing radar seekers. The Israeli Phantoms primary targetand most deadly foeduring these campaigns were Arab surface-to-air missile batteries. This aircraft was initially offered as a candidate for a U.S. lightweight fighter, but became extremely popular as an export finding its niche in the overseas market. Easyby integrating the same modern hardware used in the fourth generation. The Pakistani/Chinese JF-17 (block-3 variant) and China's Chengdu J-10B/C use a diverterless supersonic inlet, while India's HAL Tejas uses Similarly, new aerodynamic inventions such as swing wings and/or variable thrust were used on many third gen fighters, helping increase both speed and range as well. [14][15][16] An EF T1 DA (Development Aircraft trainer version) demonstrated supercruise (1.21M) with 2 SRAAM, 4 MRAAM and drop tank (plus 1-tonne flight-test equipment, plus 700kg more weight for the trainer version) during the Singapore evaluation.[17]. But perhaps the defining feature of fifth generation fighters is their stealth. The preceding generation including the classic F-86 and MiG-15 types but these were shown, in time, to be interim post-World War 2 developments awaiting replacement. The three-dimensional TVC nozzles of the Sukhoi Su-30MKI are mounted 32 outward to longitudinal engine axis (i.e. Like other modern F-4s, they can deploy advanced ordnance such as Paveway bombs, HARM anti-radar missiles and 3,000-pound Popeye missiles with a range of 48 miles.
