", "Does China's J-20 rival other stealth fighters? 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. Almost all avionics on these aircraft are digital, with the aircraft being programmed through millions of lines of code. 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. This page was last edited on 8 January 2021, at 15:03 (UTC). Ground fire shot down 474 Phantoms in all services, as the heavy-lifting Phantom fighters did double duty as ground-attack aircraft. [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. 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. With many air forces using their second gen fighters in roles beyond aerial superiority, third generation fighters were designed for multirole capabilities. In one engagement on the first day of the Yom Kippur War in 1973, 28 Egyptian MiGs attacked Ofir Air Base. During this period, maneuverability was enhanced by relaxed static stability, made possible by introduction of the fly-by-wire (FBW) flight-control system, which in turn was possible due to advances in digital computers and system-integration techniques. The Terminators are primarily ground-attack planes with some notoriety. This will make the 3rd generation fighters vulnerable and unarmed, which reignites the flexibility of the 4th generation fighters. Other existing thrust-vectoring aircraft, like the F-22, have nozzles that vector in one direction. But surely the electronics and instruments are out of date? Air-to-surface missiles (ASM) equipped with electro-optical (E-O) contrast seekers such as the initial model of the widely used AGM-65 Maverick became standard weapons, and laser-guided bombs (LGBs) became widespread in effort to improve precision-attack capabilities. In some respects, yes, if you discount the fact the J-8 stemmed from a modernization of the MiG-21F. Ralph Wetterhahn Air & Space Magazine, January 01, 2009, Articles incorporating text from Wikipedia. The 3rd Generation Fighter crop was headlined by such classic types as the American Century series and Soviet MiG-17 and MiG-21 types. These are the fastest third-generation jet fighters. Military Wiki is a FANDOM Lifestyle Community. McDonnell Douglas F-15E/EX Strike Eagle/Eagle II, "CRS RL33543: Tactical Aircraft Modernization", "National Defense Authorization Act for Fiscal Year 2010 (Enrolled as Agreed to or Passed by Both House and Senate)", "Russia to Upgrade Su-30SM Fighter Jets in 2018", "A Liability Called Rafale | Point of View", "Is Japan Facing a Shortage of Fighter Aircraft? The primary sensor for all modern fighters is radar. Eventually, the Air Force upgraded all of its F-4Es with wing-slats that significantly improved maneuverability at a slight cost in speed. 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. Fighter jets of the third generation are categorized for their multi-role capability . The table below shows how some authors have divided up the generations. An RF-4 reconnaissance plane was shot down over Syria in 2012, and three F-4s crashed in 2015earning them the appellation Flying Coffins in the Turkish media. Coupled with inventions and advances in other technologies like fly-by-wire, composite materials and digital avionics, fourth generation fighters were designed to be fighters first and foremost but adaptable enough that air forces could use them in the same multirole capacities their third generation forebearers had. While the DAPA calls the KF-21 a 4.5-generation fighter jet because it lacks, for instance, an internal weapons bay that increases stealthiness, analysts say it may be able to fly higher and . 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. Japan maintains the same number of F-4EJ Kais upgraded with pulse-Doppler radars and anti-ship missiles. The Air Forces Phantoms claimed 107 air-to-air kills for 33 lost to MiGs, and the Marine Corps claimed three. This produces a corkscrew effect, further enhancing the turning capability of the aircraft. The F-4s primary problem was that it had no built-in cannon. 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. Not really. Theyve bombed Kurdish PKK fighters in Turkey and Iraq in 2015 and 2016. 9 Lockheed F-104 Starfighter (Mach 2) Via NASA Starfighter, the name alone sounds fast and deadly. Five generations are now widely recognised, with the development of a sixth under way. Powered by twin Guizhou WP-13B engines with afterburners, the J-8 top out at Mach 1.8. How could the F-4 possibly keep up in this new environment? These aging aircraft will be replaced by low-houred F-5N/F acquired from the Swiss Air Force surplus by United States Navy (USN). These are the manly maturation of 2nd generation and addition of innovation. 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. "Flying Qualities of Relaxed Static Stability Aircraft - Volume I: Flying Qualities Airworthiness Assessment and Flight Testing of Augmented Aircraft." The Air Forces Phantoms claimed 107 air-to-air kills for 33 lost to MiGs, and the Marine Corps claimed three. First shown in 1960, the J-8 appeared in various . 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. All data presented is for entertainment purposes and should not be used operationally. Such a 4th generation aircraft requires a computerised FBW flight control system (FLCS) to maintain its desired flight path.[10]. [1][15][14], Future types at an early stage of development are expected to have even further enhanced capabilities and have become known as a sixth generation. Fourth Generation - 1970 to 1990 Editorial Team F 16 Fighting Falcon 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. The Israeli Phantoms primary targetand most deadly foeduring these campaigns were Arab surface-to-air missile batteries. The faceting reflected radar beams highly directionally, leading to brief "twinkles", which detector systems of the day typically registered as noise, but even with digital FBW stability and control enhancement, the aerodynamic performance penalties were severe and the F-117 found use principally in the night ground-attack role. [24] The IAI Lavi used an S-duct air intake to prevent radar waves from reflecting off the engine compressor blades, an important aspect of fifth-generation fighter aircraft to reduce frontal RCS. Experience the power of a third-generation, semi-American aircraft. [1] With range and payload capabilities that rivalled that of World War II bombers such as B-24 Liberator, the Phantom would became a highly successful multi-role aircraft. ; Text is available under the Creative Commons Attribution-ShareAlike License 3.0; additional terms may . The Phantoms fundamental flaws were corrected by 1970while more recently, Phantoms have had their avionics and ordnance upgraded to modern standards. Guns proved unsuitable at such high speeds, while the need for multirole capability in battlefield support was rediscovered. 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. 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 F-15 is also deliberately unlike the F-4. China's new multi-role fighter jet J-10C began combat duty Monday, the People's Liberation Army (PLA) air force announced. F-8 Crusader (USA)1957 3rd generation fighter jet. As these appeared piecemeal, designers returned to the fighter first and foremost, but with support, roles mapped out as anticipated developments. The third- generation jet fighter was the class of fighters developed between the early 1960s to the 1970s. The last American F-4s would see action during Operation Desert Storm, before being retired in 1996. [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). As an Amazon Associate I earn from qualifying purchases. The Israeli Phantoms primary targetand most deadly foeduring these campaigns were Arab surface-to-air missile batteries. But when the F-4 confronted the lighter-weight MiG-17 and MiG-21 fighters of the North Vietnamese air force in 1965, the Phantom suffered. . Third-generation fighters were often designed primarily as interceptors, being built around speed and air-to-air missiles. 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. The Phantom still sees service. 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. [12][clarification needed] Some accounts have subdivided the 4th generation into 4 and 4.5, or 4+ and 4++. But surely the electronics and instruments are out of date? 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. 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. This technique, called RSS, was incorporated to further enhance the aircraft's performance. Using this method, German MiG-29 using helmet-displayed IRST systems were able to acquire a missile lock with greater efficiency than USAF F-16 in wargame exercises. Copyright 2023 Center for the National Interest All Rights Reserved. Key Point:The Phantom has proven both versatile and adaptable over time. The weapons officer in the rear-seat could operate the planes advanced radar, communication and weapons systems while the pilot focused on flying. In response to the increasing American emphasis on radar-evading stealth designs, Russia turned to alternate sensors, with emphasis on IRST sensors, first introduced on the American F-101 Voodoo and F-102 Delta Dagger fighters in the 1960s, for detection and tracking of airborne targets. To offset this, IRST systems can incorporate a laser rangefinder in order to provide full fire-control solutions for cannon fire or for launching missiles. The Eurofighter Typhoon introduced the PIRATE-IRST, which was also retrofitted to earlier production models. Its a heavy, twin-engine, two-seat fighterand an agile dogfighter. With variable-geometry wings, the supersonic F-111 introduced the Pratt & Whitney TF30, the first turbofan equipped with afterburner. Salomon has been interested in aviation ever since his parents took him on a Boeing 720 to see his relatives. The Phantom reportedly acquitted itself well versus Iraqi MiGs, and carried out several long-range raids on the Iraqi airfields.

", "Air Force Looks at the Benefits of Using CPCs on F-16 Black Boxes. The F-5N/Fs are third-generation F-5 fighter aircraft designed for replacement of the F-5A/B/E production models. [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. 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. As the war progressed, so did the sophistication of fighter aircraft. 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. [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]. No matter what the public thought of and praised third generation fighters like the F-4, they were no longer fit for purpose. Types such as the McDonnell Douglas F-4 Phantom, General Dynamics F-111, Mikoyan-Gurevich MiG-23, Sukhoi Su-17, Shenyang J-8, and Hawker Siddeley Harrier had varying degrees of success. In Vietnam, the ratio was closer to two to one (including other aircraft types besides the Phantom). Early fourth-generation fighters like the F-15 Eagle and F-14 Tomcat retained electromechanical flight hydraulics. [22] Many of these types remain in frontline service in 2022. Due to the widely varying missions third gen fighters would be used in, third gen fighters were given a wide range of new avionics systems, including beyond visual range radars, terrain-warning systems and electronic countermeasures (ECMs) for fooling enemy radars. 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. By mid-WWII, both Allied and Axis engineers had built working jet engines and the aircraft theyd power. The Air Force didnt realize those early missiles were terrible. At the same time, the increasing cost of military aircraft in general and the demonstration of the success of aircraft such as the F-4 Phantom II gave rise to the popularity of multi-role fighter aircraft in line . "Air Force Fighter Acquisition since 1945", "Five Generations of Jet Fighter Aircraft", "War heats up between Lockheed Martin and Boeing in bid to replace jets", "Is Saab's New Gripen The Future Of Fighters? An unstable aircraft can therefore be made more maneuverable. [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]. 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. These aircraft are assigned to Government facilities, namely, NAS Key West, Florida, MCAS Yuma, Arizona, and NAS Fallon, Nevada. Some designers resorted to variable geometry or vectored thrust in an attempt to reconcile these opposites. A few even have varying degrees of AI installed to assist the pilot during flight, especially in a dogfight! McDonnell Douglas F-4G Phantom II Contents 1 Development 2 Electronics 3 Weapons 4 Specialization 5 Aircraft 5.1 Canceled Aircraft 6 References Development It was now possible to combine the C3, fighter and ground support roles in a single, agile aircraft. A number of technologies would be tried for Vertical/Short Takeoff and Landing, but thrust vectoring would be successful on the Harrier jump jet. The American Century series such as the Lockheed F-104 Starfighter, as well as the Russian MiG-21, English Electric Lightning and French Dassault Mirage III were typical of this era. T-50 PAK-FA (T-50-4) the prototype of the fifth generation fighter Su-57. Active Doppler radars cut through the ground clutter. 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. Low-observable radar technology emerged as an important development. 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. 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. 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. 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. Different authorities have identified different technology jumps as the key ones, dividing fighter development into different numbers of generations. Other famous third generation fighters include the Dassault Mirage F1, Hawker Siddeley Harrier, and MiG-23 . The 4.5-generation fighters are therefore generally less expensive, less complex, and have a shorter development time than true fifth-generation aircraft, while maintaining capabilities significantly in advance of those of the original fourth generation. Many of these aircraft, like the Messerschmitt Me 262 and Gloster Meteor, saw active (albeit limited) combat during the war. The aircraft began development in the 1980s and entered active service in 2005, with the prototype unveiled in 1989. The requirements for such a fighter remain under debate. The F-4 saw extensive use in Israeli service, scoring 116 air-to-air kills against the Egyptian and Syrian air forces, starting in 1969 during the War of Attrition. Over the course of the 1960s, increasing combat experience with guided missiles demonstrated that combat would devolve into close-in dogfights. Thrust vectoring was originally introduced in the Hawker Siddeley Harrier for vertical takeoff and landing, and pilots soon developed the technique of "viffing", or vectoring in forward flight, to enhance manoeuverability. This aircraft has an upward opening canopy, which is hinged at the rear. The second generation jet fighters existed between the mid-1950s to the early 1960s. Among the most famous fourth gen fighters are the Saab Viggen, F-16, Panavia Tornado, Su-27 and Harrier II. As advances in stealthy materials and design methods enabled smoother airframes, such technologies began to be retrospectively applied to existing fighter aircraft. The Falcon missiles were even worse, and the Pentagon later withdrew them from service. 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. Hoh, Roger H. and David G. Mitchell. Most aircraft are designed with positive static stability, which induces an aircraft to return to its original attitude following a disturbance. 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. More. The F-4E model finally came with an internal M161 Vulcan cannon. Full-span leading-edge flaps work in conjunction with trailing-edge flaps and are operated by a control on the pilot's throttle quadrant. The introduction of the swept wing allowed transonic speeds to be reached, but controllability was often limited at such speeds. In contrast, a preceding fourth generation filled in the gap since the F-15/16 era. During the 1970s, early stealth technology led to the faceted airframe of the Lockheed F-117 Nighthawk ground-attack aircraft.
