Iran received 225 F-4s from the United States prior to the Iranian Revolution. In December 1970, Northrop Grumman began development and production on the F-5A-21, an aircraft design that emphasized maneuverability rather than high speed and was officially reclassified as the F-5E. Powered by twin Guizhou WP-13B engines with afterburners, the J-8 top out at Mach 1.8. Manage all your favorite fandoms in one place! In the past, high-flying radars had trouble detecting low-flying aircraft because the radar waves bouncing off the ground created a cluttering effect. Other famous third generation fighters include the Dassault Mirage F1, Hawker Siddeley Harrier, and MiG-23. The Air Forces Phantoms claimed 107 air-to-air kills for 33 lost to MiGs, and the Marine Corps claimed three. Third-generation jet fighter (1965-1975) The archetype of this generation is the McDonnell Douglas F-4 Phantom II, the US jet fighter model with the highest production number to date. The Phase Depot Maintenance (PDM) required modifications to USN configuration provides a safer, lower-flight time Adversary aircraft with increased capability for Department of Navy (DoN) pilots. Classification of fighter aircraft c.19702000. 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. Studies showed that 45 percent of Vietnam-era AIM-7s and 37 percent of AIM-9s failed to either launch or lock on, and after evasive maneuvers, the probability of achieving a kill fell to eight percent and 15 percent for the two types, respectively. The exact criteria for the various generation steps are not universally agreed on and are subject to some controversy. The Eurofighter Typhoon can cruise around Mach 1.2 without afterburner, with the maximum level speed without reheat is Mach 1.5. [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. [5][6] This effectively condensed the previous classifications to three generations. Supercruise is the ability of a jet aircraft to cruise at supersonic speeds without using an afterburner. Direct government involvement was spared for those manufacturers located in countries like Germany and Japan, whose leaders had embarked on projects of aggressive military expansionism and needed brand new, state-of-the-art fighter aircraft to do this. With variable-geometry wings, the supersonic F-111 introduced the Pratt & Whitney TF30, the first turbofan equipped with afterburner. The F-4E model finally came with an internal M161 Vulcan cannon. By mid-WWII, both Allied and Axis engineers had built working jet engines and the aircraft theyd power. Despite numerous shortcomings that would be not be fully addressed until newer fighters, the Phantom claimed 280 aerial kills, more than any other U.S. fighter over Vietnam. Early fourth-generation fighters like the F-15 Eagle and F-14 Tomcat retained electromechanical flight hydraulics. Five generations are now commonly recognized, with the fifth representing the latest generation in service (as of 2012). Other popular first-generation jet fighters include the Heinkel He 162 and Gloster Meteor, and Lockheed F-80, which were in service during the war. Coupled with the introduction of more powerful engines and afterburners (on a mass scale), second gen fighters were able to fly supersonically during level flight instantly making them much more deadly in a dogfight. 9 Different Types of Fighter Jets (US Military), Who Pilots Air Force One & How To Become a Presidential Pilot. This arrived in the form of the American 'Century Series' fighters encompassing speed-minded developments such as the F-100 'Super Sabre', F-102 'Delta Dagger', and F-105 'Thunderchief' in the West and the MiG-19 'Farmer' and MiG-21 'Fishbed' in the East. This technique, called RSS, was incorporated to further enhance the aircraft's performance. The fourth-generation fighter is a class of jet fighters in service from around 1980 to the present, and represents design concepts of the 1970s. Dogfights forced improvements in manoeuvrability, air-to-air missiles and radar systems. 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. The F-15, which entered service in 1975, is emblematic of fourth-generation fighter aircraft that remain the mainstay of modern air forces today. [10][11] It has been suggested that Lockheed Martin "labeled the F-35 a 'fifth-generation' fighter in 2005, a term it borrowed from Russia in 2004 to describe the F-22", or that the postCold War era, low-cost approach of the Saab Gripen should qualify it as a sixth generation jet. in the horizontal plane) and can be deflected 15 in the vertical plane. The table below shows how some authors have divided up the generations. For the next-generation F-22 and F-35, the U.S. will use low probability of intercept capacity. We would like to separate major technology leaps in the historical develop. The Fourth Generation Fighter is the modern standard in combat warplanes. China's last J-7 fighter jets may leave active service this year, according to Chinese state media. 3M claims the earplugs were safe. Navy pilots went on to score a superior kill ratio over Vietnam of 40 victories for seven planes lost in air-to-air combat. Stealth technologies also seek to decrease the infrared signature, visual signature, and acoustic signature of the aircraft. Other existing thrust-vectoring aircraft, like the F-22, have nozzles that vector in one direction. fifth gen fighters include the F-35 Lightning, Sukhoi Su-57, Shenyang FC-31, F-22 Raptor and Chengdu J-20. Whereas the premier third-generation jet fighters (e.g., the F-4 and MiG-23) were designed as interceptors with only a secondary emphasis on maneuverability, interception has been relegated to a secondary role in the fourth generation, with a renewed emphasis on close-range dogfighting and maneuverability. 3rd Generation of jet fighters. improved air-to-air missiles improved radar systems other avionics guns remained standard equipment The Israeli Phantoms primary targetand most deadly foeduring these campaigns were Arab surface-to-air missile batteries. The third generation was a continuation in researches of advanced avionics, aerodynamics performance and air guided missiles. Studies showed that 45 percent of Vietnam-era AIM-7s and 37 percent of AIM-9s failed to either launch or lock on, and after evasive maneuvers, the probability of achieving a kill fell to eight percent and 15 percent for the two types, respectively. [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]. Plaintiffs claim the earplugs were defective, causing them hearing loss and tinnitus. *Third-Generation: Supersonic flight, pulse radar, and missiles that can engage opponents from beyond visual range *Fourth-Generation: High levels of agility, some degree of sensor fusion, pulse-doppler radar, reduced radar signature, fly-by-wire, look down/shoot down missiles, and more. The only other frontline fighter to serve in all three services before or since is the F-35. (Recommended: 5 Greatest Fighter Planes of All-Time). [26][27] Specific requirements are anticipated by some observers to crystallize around 2025. Instead, it relied entirely on newly-introduced air-to-air missilesthe radar-guided AIM-7 Sparrow, the heat-seeking AIM-9 Sidewinder and the older AIM-4 Falcon. 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. It is China's third-generation supersonic fighter and made its debut . The Korean War of 1950-1953 forced a major rethink. 9/10 Lockheed F-104 Starfighter (Mach 2) Interceptor types emerging after the war used after-burning engines to give Mach 2 performance, while radar and infrared homing missiles greatly improved their accuracy and firepower. These measure IR radiation from targets. Such aircraft had previously been large transport types adapted for the role, but information technology had advanced to the point that a much smaller and more agile plane could now carry the necessary data systems. The McDonnell-Douglas F-4 Phantom was designed around radar and missiles as an all-weather interceptor, but emerged as a versatile strike bomber nimble enough to prevail in air combat, adopted by the U.S. Navy, Air Force and Marine Corps. The aircraft began development in the 1980s and entered active service in 2005, with the prototype unveiled in 1989. Enhancements to improve the aerodynamic performance of third-generation fighters included flight control surfaces such as canards, powered slats, and blown flaps. 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.

All written content, illustrations, and photography are unique to this website (unless where indicated) and not for reuse/reproduction in any form. 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. This is an online quiz called 3rd Generation Jet Fighters. In Vietnam, the ratio was closer to two to one (including other aircraft types besides the Phantom). Fourth-generation designs are heavily influenced by lessons learned from the previous generation of combat aircraft. Baker 2018, Chapter 1: Genesis of the Generations. There is a printable worksheet available for download here so you can take the quiz with pen and paper. In 2004, Aerospaceweb listed one such division into five generations. McDonnell Douglas F-4G Phantom II Contents 1 Development 2 Electronics 3 Weapons 4 Specialization 5 Aircraft 5.1 Canceled Aircraft 6 References Development However, the F-4s problems began to recede. They were expected to carry a wide range of weapons and other ordnance, such as air-to-ground missiles and laser-guided bombs, while also being able to engage in air-to-air interception beyond visual range. Key point:The F-4 served for a long time and even now serve as target practice drones. The Israelis pioneered the art of Phantom upgrades in the 1980s with the Phantom 2000 Kurnass, or Sledgehammer. Though retired from Israeli service in 2004, Israeli firms went on to upgrade Greeces 41 Peace Icarus Phantoms, equipping them with ANPG-65 pulse-Doppler radars and the ability to fire AMRAAM missiles. 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. ", https://en.wikipedia.org/w/index.php?title=Fourth-generation_fighter&oldid=1139513570, Short description is different from Wikidata, Creative Commons Attribution-ShareAlike License 3.0. IRST sensors have now become standard on Russian aircraft. 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. In 1972, an F-4 piloted by Maj. Phil Handley shot down a MiG-19 with his planes gunthe only recorded aerial gun kill performed at supersonic speed. South Korea still has 71 F-4Es (only modestly upgraded) in its 17th Fighter Wing. The gun was de-emphasized and, in some cases, eliminated. Instead, it relied entirely on newly-introduced air-to-air missilesthe radar-guided AIM-7 Sparrow, the heat-seeking AIM-9 Sidewinder and the older AIM-4 Falcon. [11] The MiG-35 with its RD-33OVT engines with the vectored thrust nozzles allows it to be the first twin-engined aircraft with vectoring nozzles that can move in two directions (that is, 3D TVC). The F-4s primary problem was that it had no built-in cannon. In the Korean War, the U.S. Air Force had shot down between six and 10 enemy fighters for every one of its aircraft lost in air-to-air combat. Not really. Late to the party, the J-8B was a third gen fighter while the competition had moved on.

A few famous (or should I say infamous?) [3] A NASA web publication divides jet development into five stages; pioneer (straight wing), swept wing, transonic, the 1960s and 1970s on, culminating in types such as the F-15, F-16 and AV-8A. Furthermore, the F-4 came in both ground- and carrier-based models and served in the U.S. Air Force, Navy and Marines. The concept of a third generation fighter is perhaps best exemplified by the F-4 Phantom, an aircraft synonymous with the Vietnam War. Full-span leading-edge flaps work in conjunction with trailing-edge flaps and are operated by a control on the pilot's throttle quadrant. Most were even capable of supersonic flight, though this was usually limited to controlled drives rather than level flying. In practice, air-to-air missiles of the time, despite being responsible for the vast majority of air-to-air victories, were relatively unreliable, and combat would quickly become subsonic and close-range. Yet whilst the war in Vietnam made the F-4 a household name on both sides of the Iron Curtain, it also revealed the fundamental flaws in third generation aircraft technology just as the Korean War had done for first generation fighters a decade earlier. The swan song of the Israeli Phantom force came during Israels 1982 intervention in the War in Lebanon, when Phantomsescorted by new F-15s and F-16swiped out all 30 of Syrias SAM batteries in the Bekaa Valley in one day without losing a single plane in Operation Mole Cricket 19. Such a 4th generation aircraft requires a computerised FBW flight control system (FLCS) to maintain its desired flight path.[10]. Single-Seat Supersonic Interceptor Aircraft, Single-Seat, Single-Engine Supersonic Interceptor Aircraft, Long-Range Strategic Medium Bomber / Tactical Strike Aircraft, VTOL Strike / Reconnaissance / Trainer Aircraft, Single-Seat High-Speed Fighter / Interceptor Aircraft, Multirole / Carrierbased Fighter / Strike Fighter Aircraft, Twin-Engine Interceptor / Reconnaissance Aircraft, Single-Seat Jet-Powered Fighter / Fighter-Bomber Aircraft, Supersonic Jet-Powered Fighter / Interceptor Aircraft, Single-Seat Fighter-Bomber / Air Superiority / Tactical Reconnaissance Aircraft, Single-Seat Fighter-Bomber / Reconnaissance / Wild Weasel. Weighing in at 30,000 pounds unloaded, its enormous J79 twin engines gave (and still gives) the aircraft excellent thrust, propelling the heavy airframe over twice the speed of sound at a maximum speed of 1,473 miles per hour. Some late derivatives of the early types, such as the F-15SA Strike Eagle for Saudi Arabia, have included upgrading to FBW. A European consortium GTDAR is developing an AESA Euroradar CAPTOR radar for future use on the Typhoon. Almost all avionics on these aircraft are digital, with the aircraft being programmed through millions of lines of code. Modern F-4s can also fire the full range of modern ordnance such as the advanced AIM-120C AMRAAM air-to-air missile with a range of 65 miles, precision-guided munitions such as the AGM-65 Maverick, and late model Sparrow and Sidewinder missiles. Ground fire shot down 474 Phantoms in all services, as the heavy-lifting Phantom fighters did double duty as ground-attack aircraft. Due to their advanced age, first generation fighters have been retired for a considerable length of time, now finding themselves primarily as museum exhibits, whilst a few remain in airworthy condition as warbirds. The huge advance of digital computation and mobile networking, which began in the 1990s, led to a new model of sophisticated forward C3 (command, control and communications) presence above the battlefield. 11ff. For example, Lockheed Martin has applied the term "fifth generation" to its F-22 and F-35 aircraft, but this has been challenged by its competitors Eurofighter GmbH and Boeing IDS. The F-4s primary problem was that it had no built-in cannon. Japan maintains the same number of F-4EJ Kais upgraded with pulse-Doppler radars and anti-ship missiles. In the Korean War, the U.S. Air Force had shot down between six and 10 enemy fighters for every one of its aircraft lost in air-to-air combat. Check 'third-generation jet fighter' translations into Hebrew. New J79 engines even dealt with the problem of the F-4s visible black smoke. Easyby integrating the same modern hardware used in the fourth generation. Military Wiki is a FANDOM Lifestyle Community. Baker 2018, Chapter 3: Generation Rising. With many air forces using their second gen fighters in roles beyond aerial superiority, third generation fighters were designed for multirole capabilities. These aging aircraft will be replaced by low-houred F-5N/F acquired from the Swiss . These aircraft placed an emphasis on a multi-role capability. The list does not include projects that were cancelled before an aircraft was built or fictional aircraft. More . Modern F-4s can also fire the full range of modern ordnance such as the advanced AIM-120C AMRAAM air-to-air missile with a range of 65 miles, precision-guided munitions such as the AGM-65 Maverick, and late model Sparrow and Sidewinder missiles. Different authorities have identified different technology jumps as the key ones, dividing fighter development into different numbers of generations. The term 4.5 generation is often used to refer to new or enhanced fighters, which appeared beginning in the 1990s, and incorporated some features regarded as fifth generation, but lacked others. But surely the electronics and instruments are out of date? With more reliable and longer-range radars becoming more and more widespread, manufacturers have had to design fifth gen fighters to have as minimal radar cross-sections (how much it reflects radar signals) as possible. As much a computer as they are an aircraft, it is expected that fifth gen fighters will adapt to future changes in aerial combat, not through new variants, but through software updates, thus saving air forces around the world millions of dollars in the long run. Air combat manoeuvring also involves a great deal of energy management to maintain speed and altitude under rapidly changing flight conditions. The US-produced Century Series, Mirage III, English Electric Lightning and MiG-21 are all quintessential second 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. There are presently several fifth generation fighters under development, such as the TAI TFX in Turkey and Sukhoi Su-75 in Russia. The F-5N/Fs are third-generation F-5 fighter aircraft designed for replacement of the F-5A/B/E production models. Recognizing the increased obsolescence of fourth generation fighters, but also the lack of funding for new fighters nearing and following the end of the Cold War, aircraft manufacturers began developing what are sometimes called 4.5 generation fighters. The edge aside from having a more reliable powerplant first generation fighters had over their piston counterparts was their speed. In some respects, yes, if you discount the fact the J-8 stemmed from a modernization of the MiG-21F. Date Deployed: F-5N First flight: March 2003; F-5F First Flight: September 1974. The next generation of fighters were designed from the start to be multi-role. [1], In 1990, air historian Richard P. Hallion proposed a classification of jet fighters into six generations up to that time. Supercruise 2 SRAAM 6 MRAAM", "Le radar RBE2, l'arme fatale du Rafale l'export", "Type Acceptance for Block 5 Standard Eurofighter Typhoon. [22] Many of these types remain in frontline service in 2022. The next generation of fighters were designed from the start to be multi-role. The Air Force didnt realize those early missiles were terrible. Despite a design dating back to the early 1960s, the J-8 is a capable third gen fighter. Sophisticated automation and human interfaces could greatly reduce crew workload. Before, some Phantom units made do with external gun pods that vibrated excessively. Aronstein, David C. and Albert C. Piccirillo. These are a few of the preferred methods employed in some fifth-generation fighters to reduce RCS.[25][26]. These modernized Phantoms flown by the Turkish and Greek air forces can do pretty much what an F-15 can do at a much lower price. While exceptionally fast in a straight line, many third-generation fighters severely lacked in manoeuvrability, as doctrine held that traditional dogfighting would be impossible at supersonic speeds. 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. Late to the party, the J-8B was a third gen fighter while the competition had moved on. 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. 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. While exceptionally fast in a straight line, many third-generation fighters severely lacked in manoeuvrability, as doctrine held that traditional dogfighting would be impossible at supersonic speeds. The Israeli Phantoms primary targetand most deadly foeduring these campaigns were Arab surface-to-air missile batteries. This would leave third-generation fighters vulnerable and ill-equipped, renewing an interest in manoeuvrability for the fourth generation of fighters. "Flying Qualities of Relaxed Static Stability Aircraft - Volume I: Flying Qualities Airworthiness Assessment and Flight Testing of Augmented Aircraft." 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. This page was last edited on 8 January 2021, at 15:03 (UTC). Meanwhile, the growing costs of military aircraft in general and the demonstrated success of aircraft such as the F-4 Phantom II gave rise to the popularity of multirole combat aircraft in parallel with the advances marking the so-called fourth generation. Germany flew upgraded F-4Fs until 2013, and maintains them in stock in case of future need. 3rd Generation Jet Fighters Quiz Information. Developments in fighter jet technology included making them faster, more maneuverable and extending their range and payload capabilities among others. The General Dynamics YF-16, eventually developed into the F-16 Fighting Falcon, was the world's first aircraft intentionally designed to be slightly aerodynamically unstable. One of the innovations on fourth-generation jet fighters is FBW, while generation 4.5 introduced AESA radar. To improve accuracy of these, second generation fighters were fitted with rudimentary avionics, including a supersonic radar. This page was last edited on 15 February 2023, at 14:46. These formed the backbone of the Iranian fighter force during the nine-year-long war with Iraq. With no war to fight, few new fighters were put into production during the 1920s and manufacturers ceased research into developing new ones. As third gen fighters would no longer just be flying quick sorties, and instead needed much longer in the air to complete their missions, manufacturers put an even greater emphasis on increasing range and speed. Fifth-generation abilities for battlefield survivability, air superiority and ground support are being enhanced and adapted to the future threat environment.
