With no war to fight, few new fighters were put into production during the 1920s and manufacturers ceased research into developing new ones. 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. The Phantom still sees service. 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 . The term is used for those aircraft designs bridging the gap between the developments of the 1960s and 1970s and those appearing today under the Fifth Generation Fighter classification. Despite a design dating back to the early 1960s, the J-8 is a capable third gen fighter. 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. A number of new 4.5 generation types are being developed in the 2020s, post the emergence of the true 5th generation and contemporaneous with 6th generation aircraft development, these include the HAL Tejas MK 1A, CAC/PAC JF-17 Thunder Block 3, and KAI KF-21 Boramae.[23][13][9]. 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. 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. 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. The Falcon missiles were even worse, and the Pentagon later withdrew them from service. Such a fighterand its pilotwould need to be able to loiter for long periods, hold its own in combat, maintain battlefield awareness and seamlessly switch roles as the situation developed. More . 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. [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. The F-4s primary problem was that it had no built-in cannon. Other existing thrust-vectoring aircraft, like the F-22, have nozzles that vector in one direction. 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. 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. Furthermore, the F-4 came in both ground- and carrier-based models and served in the U.S. Air Force, Navy and Marines. Some late derivatives of the early types, such as the F-15SA Strike Eagle for Saudi Arabia, have included upgrading to FBW. 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. . 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. 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. Easyby integrating the same modern hardware used in the fourth generation. The next generation of fighters were designed from the start to be multi-role. ", "Air Force Looks at the Benefits of Using CPCs on F-16 Black Boxes. They were similar in most respects to their piston-engined contemporaries, having straight, unswept wings and being of wood and/or light alloy construction. 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. 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. The only other frontline fighter to serve in all three services before or since is the F-35. [26][27] Specific requirements are anticipated by some observers to crystallize around 2025. An aircraft with negative static stability, though, in the absence of control input, will readily deviate from level and controlled flight. The only other frontline fighter to serve in all three services before or since is the F-35. Infrared-homing AAMs saw their fields of view expand to 45, which strengthened their tactical usability. "Flying Qualities of Relaxed Static Stability Aircraft - Volume I: Flying Qualities Airworthiness Assessment and Flight Testing of Augmented Aircraft." The Phantom reportedly acquitted itself well versus Iraqi MiGs, and carried out several long-range raids on the Iraqi airfields. Stealth technologies also seek to decrease the infrared signature, visual signature, and acoustic signature of the aircraft. Hoh, Roger H. and David G. Mitchell. Analog avionics began to be introduced, replacing older "steam-gauge" cockpit instrumentation. 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. SAMs accounted for most of the 36 Israeli Phantoms lost in action. However, the Phantoms proliferated around the world. 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. Today, fighter jets are the backbone of the worlds air forces. Japan maintains the same number of F-4EJ Kais upgraded with pulse-Doppler radars and anti-ship missiles. 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. 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. (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. Active Doppler radars cut through the ground clutter. 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. 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. Fighter jets of the third generation are categorized for their multi-role capability . 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. Sophisticated automation and human interfaces could greatly reduce crew workload. The Air Forces Phantoms claimed 107 air-to-air kills for 33 lost to MiGs, and the Marine Corps claimed three. 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. In one engagement on the first day of the Yom Kippur War in 1973, 28 Egyptian MiGs attacked Ofir Air Base. Supercruise is the ability of a jet aircraft to cruise at supersonic speeds without using an afterburner. Jet fighter generations classify the major technology leaps in the historical development of the jet fighter. The F-15 is also deliberately unlike the F-4. (Recommended: How to Win a War with China). 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. 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. 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. 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. 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. 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. As of 2023, these are the most advanced fighters in operation. Dogfights forced improvements in manoeuvrability, air-to-air missiles and radar systems. 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.

McDonnell Douglas F-4G Phantom II Contents 1 Development 2 Electronics 3 Weapons 4 Specialization 5 Aircraft 5.1 Canceled Aircraft 6 References Development The exact criteria for the various generation steps are not universally agreed on and are subject to some controversy. The characteristics of a fifth-generation fighter are not universally agreed upon and not every fifth-generation type necessarily has them all; however, they typically include . Vietnam had been a war that didnt just need multirole fighter-bombers, but aircraft that were as maneuverable as they fast. The Heinkel He 162 and Gloster Meteor also saw wartime service, while types such as the de Havilland Vampire and Lockheed F-80 were still working up to operational service when the war ended.

Ground fire shot down 474 Phantoms in all services, as the heavy-lifting Phantom fighters did double duty as ground-attack aircraft. All developed and/or introduced in between 1960-1975. South Korea still has 71 F-4Es (only modestly upgraded) in its 17th Fighter Wing. France introduced its first indigenous AESA radar, the RBE2-AESA built by Thales in February 2012[19] for use on the Rafale. Third gen fighters were also designed to host an equally wide range of weapons, from air-to-air missiles, to air-to-surface missiles and laser guided bombs (LGBs). As an Amazon Associate I earn from qualifying purchases. Despite a design dating back to the early 1960s, the J-8 is a capable third gen fighter. The gun was de-emphasized and, in some cases, eliminated. 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. [6] Although details differ, the basic classification into five generations has since been widely adopted.[7][8][9]. The 4.5-generation fighters have introduced integrated IRST systems, such as the Dassault Rafale featuring the optronique secteur frontal integrated IRST.
