3rd Generation of jet fighters. The Lockheed Martin F-22 Raptor is an American twin-engine, all-weather, single-seat, stealth, and fifth-generation fighter jet. Fifth gen fighters have inherited the maneuverability of their fourth and 4.5 gen predecessors (and are arguably more so) but have lost some of the speed associated with these generations due to more pressing operational requirements. These aging aircraft will be replaced by low-houred F-5N/F acquired from the Swiss Air Force surplus by United States Navy (USN). Germany flew upgraded F-4Fs until 2013, and maintains them in stock in case of future need. (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. These measure IR radiation from targets. These are a few of the preferred methods employed in some fifth-generation fighters to reduce RCS.[25][26]. 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. 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. Key Point:The Phantom has proven both versatile and adaptable over time. This will make the 3rd generation fighters vulnerable and unarmed, which reignites the flexibility of the 4th generation fighters. The early Phantoms could carry 18,000 pounds of munitionsthree times what the huge B-17 bombers of World War II typically carried. As of 2023, these are the most advanced fighters in operation. The F-5N is a single seat, twin-engine, tactical fighter and attack aircraft providing simulated air-to-air combat training manufactured by Northrop Grumman Corporation. This is an online quiz called 3rd Generation Jet Fighters. The Korean War of 1950-1953 forced a major rethink. Infrared-homing AAMs saw their fields of view expand to 45, which strengthened their tactical usability. The Air Forces Phantoms claimed 107 air-to-air kills for 33 lost to MiGs, and the Marine Corps claimed three. Indeed, the notion of a generation fighter isnt even that old: it was coined in the 1990s and is generally associated with the US aviation industry by the international community as a whole. Five generations are now widely recognised, with the development of a sixth under way. Jet fighter generations classify the major technology leaps in the historical development of the jet fighter. In one engagement on the first day of the Yom Kippur War in 1973, 28 Egyptian MiGs attacked Ofir Air Base. Their wide-scale use revealed the immense shortfalls of first gen fighters; theyd advanced so much but still had a long way to go. [5][6] This effectively condensed the previous classifications to three generations. The Phantom still sees service. The 4.5-generation fighters have introduced integrated IRST systems, such as the Dassault Rafale featuring the optronique secteur frontal integrated IRST. In some respects, yes, if you discount the fact the J-8 stemmed from a modernization of the MiG-21F. Technological advances in aerodynamics, propulsion and aerospace building materials . 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. Avionics can often be swapped out as new technologies become available; they are often upgraded over the lifetime of an aircraft. 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. The next generation of fighters were designed from the start to be multi-role.

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. The term generation first appeared in the 1990s, according to the Royal Australian Air Force's Air Power Development Centre Bulletin: "to make sense of the leap-frogging improvements in performance to jet fighter aircraft brought about through major advances in aircraft design, avionics, and weapon systems", and proposes that a . The F-15, which entered service in 1975, is emblematic of fourth-generation fighter aircraft that remain the mainstay of modern air forces today. KAI KF-21 Boramae is a purpose-built joint South Korean/Indonesian 4.5-generation fighter program. Israeli upgrades contributed to the Turkish air forces Terminator 2020, which has additional wing strakes for improved maneuverability. 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. This page was last edited on 15 February 2023, at 14:46. It is China's third-generation supersonic fighter and made its debut . No matter what the public thought of and praised third generation fighters like the F-4, they were no longer fit for purpose. 3rd Generation Jet Fighters Quiz Information. The aircraft began development in the 1980s and entered active service in 2005, with the prototype unveiled in 1989. The "Military Factory" name and MilitaryFactory.com logo are registered U.S. trademarks protected by all applicable domestic and international intellectual property laws. With many air forces using their second gen fighters in roles beyond aerial superiority, third generation fighters were designed for multirole capabilities. It is China's third-generation supersonic fighter and made its debut when the PLA marked its 90th anniversary in July 2017 at Zhurihe military training base in Inner Mongolia Autonomous Region. 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. All written content, illustrations, and photography are unique to this website (unless where indicated) and not for reuse/reproduction in any form. They were also the first cadre of multi-role fighters such as the MiG-23, F-4, and Mirage III. Guns proved unsuitable at such high speeds, while the need for multirole capability in battlefield support was rediscovered. (Recommended: How to Win a War with China). Enhancements to improve the aerodynamic performance of third-generation fighters included flight control surfaces such as canards, powered slats, and blown flaps. More than 5,000 of these heavy supersonic fighters were built, and hundreds continue to serve and even see combat in several air forces today. 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. Plaintiffs claim the earplugs were defective, causing them hearing loss and tinnitus. The last American F-4s would see action during Operation Desert Storm, before being retired in 1996. Despite a design dating back to the early 1960s, the J-8 is a capable third gen fighter. Five generations are now commonly recognized, with the fifth representing the latest generation in service (as of 2012). IRST sensors have now become standard on Russian aircraft. It is one of the best fighter jets in the world. A European consortium GTDAR is developing an AESA Euroradar CAPTOR radar for future use on the Typhoon. Also From TNI: Why Japan Really Lost Pearl Harbor. T-50 PAK-FA (T-50-4) the prototype of the fifth generation fighter Su-57. 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. The U.S. explored fitting the technology to the F-16 and the F-15, but did not introduce it until the fifth generation arrived. All modern European and American aircraft are capable of sharing targeting data with allied fighters and AWACS planes (see JTIDS). The Russian MiG-31 interceptor also has some datalink capability. 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. 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 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. The Falcon missiles were even worse, and the Pentagon later withdrew them from service. 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 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. 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. [6] Although details differ, the basic classification into five generations has since been widely adopted.[7][8][9]. ", "Air Force Looks at the Benefits of Using CPCs on F-16 Black Boxes. The advent of more economical turbofan engines brought extended range and sortie times, while increased thrust could only partly deliver better performance and manoeuvrability across the speed range. carbon-fiber composite in manufacturing. But surely the electronics and instruments are out of date? The Eurofighter Typhoon can cruise around Mach 1.2 without afterburner, with the maximum level speed without reheat is Mach 1.5. This would leave third-generation fighters vulnerable and ill-equipped, renewing an interest in manoeuvrability for the fourth generation of fighters. 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. Some designers resorted to variable geometry or vectored thrust in an attempt to reconcile these opposites. Currently, the Swiss F-5N Replacement Program replaces the present high-time Navy F-5Es with low-time F-5Ns allowing the USN/USMC to operate the F-5N aircraft to Fiscal Year (FY) 2015. Air-to-air missile technology dramatically improved with later versions of the Sparrow and Sidewinder. Depending on who you talk to, you may find that they class different aircraft in different generations (especially if those aircraft were produced near the end or start of a generation and theres some overlap) or that there are only four generations rather than five (mainly by the Chinese). [2] Other schemes comprising five generations up to around the same period have since been described, although the demarcation lines between generations differ. The edge aside from having a more reliable powerplant first generation fighters had over their piston counterparts was their speed. 9/10 Lockheed F-104 Starfighter (Mach 2) When the F-4 came out it in 1958 it was a revolutionary designone that went on to set several aviation records. The U.S. fielded its first modified F-15Cs equipped with AN/APG-63(V)2 AESA radars,[18] which have no moving parts and are capable of projecting a much tighter beam and quicker scans. However, positive static stability, the tendency to remain in its current attitude, opposes the pilot's efforts to maneuver. [4], In the 1990s, a different division came into use in Russia, where a "fifth generation" fighter was proposed as a counter to the Lockheed Martin F-22 Raptor. Such a 4th generation aircraft requires a computerised FBW flight control system (FLCS) to maintain its desired flight path.[10]. 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. 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. 11ff. Studies such as the US Next Generation Air Dominance (NGAD) and F/A-XX programs, UK-led BAE Systems Tempest, and Chinese development work are ongoing. 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. Fifth-generation abilities for battlefield survivability, air superiority and ground support are being enhanced and adapted to the future threat environment. Military aviation is no different. The actual number of air-to-air kills remains disputed. [22] Many of these types remain in frontline service in 2022. 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. [1], In 1990, air historian Richard P. Hallion proposed a classification of jet fighters into six generations up to that time. Although speeds had improved considerably, there was limited controllability in these jets. Ground fire shot down 474 Phantoms in all services, as the heavy-lifting Phantom fighters did double duty as ground-attack aircraft. 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. Classification of fighter aircraft c.19702000. 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. The list does not include projects that were cancelled before an aircraft was built or fictional aircraft. The gun was de-emphasized and, in some cases, eliminated. 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. In one engagement on the first day of the Yom Kippur War in 1973, 28 Egyptian MiGs attacked Ofir Air Base. The F-5 also has anti-skid brakes, Initial Navigation System (INS), ALR-87 Radar Warning Receivers (RWR), AN/APQ-159 radar and ALE-40 chaff/flare capability. By mid-WWII, both Allied and Axis engineers had built working jet engines and the aircraft theyd power. Many types were soon compromised by adaptations for battlefield support roles, and some of these would persist in new variants for multiple generations.[17]. Active Doppler radars cut through the ground clutter. While the trade-offs involved in combat aircraft design are again shifting towards beyond visual range (BVR) engagement, the management of the advancing environment of numerous information flows in the modern battlespace, and low-observability, arguably at the expense of maneuvering ability in close combat, the application of thrust vectoring provides a way to maintain it, especially at low speed. Indeed, fourth gen fighters are among the fastest aircraft ever built even faster than their fifth gen counterparts. Aronstein, David C. and Albert C. Piccirillo. The General Dynamics F-16 introduced electronic flight control and wing-body blending, while the Saab 37 Viggen broke new ground in aerodynamic configuration with its canard foreplanes. Salomon has been interested in aviation ever since his parents took him on a Boeing 720 to see his relatives. 9 Lockheed F-104 Starfighter (Mach 2) Via NASA Starfighter, the name alone sounds fast and deadly. From the start of the new millennium, advanced systems concepts such as smart helmets, sensor/data fusion and subsidiary attack drones were becoming realities. 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. [1] The further advance of microcomputers in the 1980s and 1990s permitted rapid upgrades to the avionics over the lifetimes of these fighters, incorporating system upgrades such as active electronically scanned array (AESA), digital avionics buses, and infra-red search and track. The F-4s primary problem was that it had no built-in cannon. - 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. Ground fire shot down 474 Phantoms in all services, as the heavy-lifting Phantom fighters did double duty as ground-attack aircraft. Almost all avionics on these aircraft are digital, with the aircraft being programmed through millions of lines of code. The ambitious project sought to create a versatile common fighter for many roles and services. [12][clarification needed] Some accounts have subdivided the 4th generation into 4 and 4.5, or 4+ and 4++. Later on, it was introduced to the F/A-18E/F Super Hornet and the block 60 (export) F-16 also, and will be used for future American fighters. Navy pilots went on to score a superior kill ratio over Vietnam of 40 victories for seven planes lost in air-to-air combat. 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. Japan maintains the same number of F-4EJ Kais upgraded with pulse-Doppler radars and anti-ship missiles. However, the F-4s problems began to recede. In reality that's exactly what Lockheed delivered. Not really. Date Deployed: F-5N First flight: March 2003; F-5F First Flight: September 1974. Just two Phantoms managed to scramble in defense, but they shot down seven of the attackers. The Phantoms fundamental flaws were corrected by 1970while more recently, Phantoms have had their avionics and ordnance upgraded to modern standards. 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. Most aircraft are designed with positive static stability, which induces an aircraft to return to its original attitude following a disturbance. 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. Third generation jet fighters (early 1960s to 1970) This generation witnessed improvements in manoeuvrability, and significant enhancements to the avionic suites and weapon systems. In Vietnam, the ratio was closer to two to one (including other aircraft types besides the Phantom). Growth in air combat capability focused on the introduction of improved air-to-air missiles, radar systems, and other avionics. The earliest jet fighters appeared during and after the last years of World War II. The design places particular emphasis on maneuverability rather than high speed, notably by the incorporation of maneuvering flaps. The primary sensor for all modern fighters is radar. 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. [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. To increase situational awareness and coordination, most fifth gen fighters have networked data fusion, allowing fifth gen fighters to talk to other allied fifth gen fighters nearby. The early Phantoms could carry 18,000 pounds of munitionsthree times what the huge B-17 bombers of World War II typically carried. [26][27] Specific requirements are anticipated by some observers to crystallize around 2025. Powered by twin Guizhou WP-13B engines with afterburners, the J-8 top out at Mach 1.8. 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. The changes in the fighter combat conception, new air-to-air guided missiles and the results . Many also have new types of avionics such as synthetic aperture radar (SAR) and/or infra-red search and tracking (IRST). 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. The only other frontline fighter to serve in all three services before or since is the F-35. These aircraft placed an emphasis on a multi-role capability. The F-15 is also deliberately unlike the F-4. The F-5N/Fs are third-generation F-5 fighter aircraft designed for replacement of the F-5A/B/E production models. Before, some Phantom units made do with external gun pods that vibrated excessively. They were similar in most respects to their piston-engined contemporaries, having straight, unswept wings and being of wood and/or light alloy construction. [citation needed]) They had little or no avionics, with their primary armament being manually-controlled guns. By most accounts, Korea was the point of no return for first generation fighters. When the F-4 came out it in 1958 it was a revolutionary designone that went on to set several aviation records. The F-16 is a single-seat, single-seater fighter, a third- or third-generation semi-american fighter, and one of the most successful fighters in the world. 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. To improve accuracy of these, second generation fighters were fitted with rudimentary avionics, including a supersonic radar.
