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. Whilst most third gen fighters have been retired from active military service, a select few remain in service, such as the Mirage III with the Pakistani Air Force. 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 . 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. F-8 Crusader (USA)1957 3rd generation fighter jet. 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. Low-observable radar technology emerged as an important development. 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. Fourth-generation designs are heavily influenced by lessons learned from the previous generation of combat aircraft. Perhaps the most famous 4.5 generation fighters include the Eurofighter Typhoon, Dassault Rafale, MiG-35, F/A-18 Hornet and Saab Gripen. 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. The early Phantoms could carry 18,000 pounds of munitionsthree times what the huge B-17 bombers of World War II typically carried. Many of these aircraft, like the Messerschmitt Me 262 and Gloster Meteor, saw active (albeit limited) combat during the war. New J79 engines even dealt with the problem of the F-4s visible black smoke. Some late derivatives of the early types, such as the F-15SA Strike Eagle for Saudi Arabia, have included upgrading to FBW. To do this, brand new turbofan engines were installed on third gen fighters, which were more fuel efficient than the turbojets used up until then, thus extending range. 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. In Vietnam, the ratio was closer to two to one (including other aircraft types besides the Phantom). The Phantoms fundamental flaws were corrected by 1970while more recently, Phantoms have had their avionics and ordnance upgraded to modern standards. 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. Military aviation is no different. 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. 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. 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. IRST sensors have now become standard on Russian aircraft. Eventually, the Air Force upgraded all of its F-4Es with wing-slats that significantly improved maneuverability at a slight cost in speed. [5][6] This effectively condensed the previous classifications to three generations. [19] Chinese People's Liberation Army (PLA), with a different generation system, classifies most fourth-generation fighters as the third generation. 3 - 1960-1970 - Third Generation fighter aircraft exhibit more advanced avionics, engines, and weapons. Technological advances in aerodynamics, propulsion and aerospace building materials . These measure IR radiation from targets. 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. Some designers resorted to variable geometry or vectored thrust in an attempt to reconcile these opposites. To improve accuracy of these, second generation fighters were fitted with rudimentary avionics, including a supersonic radar. 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. 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. The development of second-generation fighters were shaped by technological breakthroughs, lessons learned from the aerial battles of the Korean War, and a focus on conducting operations in a nuclear warfare environment. A few famous (or should I say infamous?) Powered by twin Guizhou WP-13B engines with afterburners, the J-8 top out at Mach 1.8. The 4.5-generation fighters have introduced integrated IRST systems, such as the Dassault Rafale featuring the optronique secteur frontal integrated IRST. Baker 2018, Chapter 3: Generation Rising. These are the manly maturation of 2nd generation and addition of innovation. [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. The F-4s primary problem was that it had no built-in cannon. When the F-4 came out it in 1958 it was a revolutionary designone that went on to set several aviation records. The idea of using aviation for warfare predates even the Wright Brothers first flight. China's last J-7 fighter jets may leave active service this year, according to Chinese state media. [12] The technology has been fitted to the Sukhoi Su-47 Berkut and later derivatives. Japan maintains the same number of F-4EJ Kais upgraded with pulse-Doppler radars and anti-ship missiles. Eventually, the Air Force upgraded all of its F-4Es with wing-slats that significantly improved maneuverability at a slight cost in speed. Air-to-air missile technology dramatically improved with later versions of the Sparrow and Sidewinder. 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. Today, fighter jets are the backbone of the worlds air forces. 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. 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. Key Point:The Phantom has proven both versatile and adaptable over time. The primary sensor for all modern fighters is radar. How could the F-4 possibly keep up in this new environment? The exact criteria for the various generation steps are not universally agreed on and are subject to some controversy. The F-5N/Fs are third-generation F-5 fighter aircraft designed for replacement of the F-5A/B/E production models. These formed the backbone of the Iranian fighter force during the nine-year-long war with Iraq. 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. WWII-style manual guns werent particularly effective at the speeds most first gen fighters flew at, necessitating the need for much faster air-to-air missiles. Easyby integrating the same modern hardware used in the fourth generation. 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. Many types were soon compromised by adaptations for battlefield support roles, and some of these would persist in new variants for multiple generations.[17]. Fourth Generation Fighter types incude the American F-16 Fighting Falcon, the F/A-18 Hornet, the Chengdu J-10 and the MiG-29 Fulcrum . The weapons officer in the rear-seat could operate the planes advanced radar, communication and weapons systems while the pilot focused on flying. Japan maintains the same number of F-4EJ Kais upgraded with pulse-Doppler radars and anti-ship 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. ", "Characterization of Radar Cross Section of Carbon Fiber Composite Materials", "Lockheed-Martin F-35 Joint Strike Fighter Analysis 2002. 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. 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. 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 . 3rd Generation of jet fighters. 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. [+] China's new multi-role fighter jet J-10C began combat duty Monday, the People's Liberation Army (PLA) air force announced.

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. 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. Five generations are now widely recognised, with the development of a sixth under way.
