Its a heavy, twin-engine, two-seat fighterand an agile dogfighter. These are the fastest third-generation jet fighters. 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 Air Forces Phantoms claimed 107 air-to-air kills for 33 lost to MiGs, and the Marine Corps claimed three. The exact criteria for the various generation steps are not universally agreed on and are subject to some controversy. "Flying Qualities of Relaxed Static Stability Aircraft - Volume I: Flying Qualities Airworthiness Assessment and Flight Testing of Augmented Aircraft." [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. 3rd generation fighter jet are mainly developed between 1960s to 1970s.. In one engagement on the first day of the Yom Kippur War in 1973, 28 Egyptian MiGs attacked Ofir Air Base. 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). Bringing together and integrating such advances, along with those of the fourth generation, created what has become known as the fifth generation of fighters. [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. 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. [26][27] Specific requirements are anticipated by some observers to crystallize around 2025. 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.

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. Key Point:The Phantom has proven both versatile and adaptable over time. 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 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. 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. The introduction of the swept wing allowed transonic speeds to be reached, but controllability was often limited at such speeds. Third generation jet fighters (early 1960s to 1970) This generation witnessed improvements in manoeuvrability, and significant enhancements to the avionic suites and weapon systems. Furthermore, the Phantoms J79 engines produced thick black smoke, which combined with the aircrafts larger size, made it easier to spot and target from a distance.
