In September 2010, it was reported that India and Russia had agreed on a preliminary design contract where each country invests $6 billion development of the FGFA fighter was expected to take 8–10 years. In 2007, Russia and India agreed to jointly develop the Fifth Generation Fighter Aircraft Programme (FGFA) for India. T-50 aerodynamic condensation at MAKS-2015 The technologies being tested on board the Su-57 are supposed to be mainly control and navigation systems, including weapon systems. Since the Su-57 will not likely be developed into an unmanned version, the aircraft is being currently used also as a testbed for technologies being developed for Russia’s future sixth-generation combat system that in its basic version will be an unmanned aerial vehicle (UAV) possessing an ability to be optionally manned. In 2009, the aircraft’s design was officially approved. On 8th August 2007, Russian Air Force Commander-in-Chief (CinC) Alexander Zelin was quoted by Russian news agencies that the programme’s development stage was complete and construction of the first aircraft for flight testing would begin, and that by 2009 there would be three fifth-generation aircraft ready. NPO Saturn is the lead contractor for the interim engines Saturn and MMPP Salyut will compete for the definitive second stage engines. Following a competition held in 2003, the Tekhnokompleks Scientific and Production Center, Ramenskoye Instrument Building Design Bureau, the Tikhomirov Scientific Research Institute of Instrument Design (NIIP), the Ural Optical and Mechanical Plant (UOMZ) in Yekaterinburg, the Polet firm in Nizhny Novgorod and the Central Scientific Research Radio Engineering Institute in Moscow were selected for the development of the PAK-FA’s avionics suite. The Novosibirsk Aircraft Production Association (NAPO) is manufacturing the new multi-role fighter at Komsomol’sk-on-Amur along with Komsomolsk-on-Amur Aircraft Production Association (KnAAPO), and final assembly is to take place at Komsomol’sk-on-Amur. To reduce the PAK FA’s developmental risk and spread out associated costs, as well as to bridge the gap between it and older previous generation fighters, some of its technology and features, such as propulsion and avionics, were implemented in the Sukhoi Su-35S fighter, an advanced variant of the Su-27. In 2002, Sukhoi was selected over Mikoyan as the winner of the PAK FA competition and would lead the design of the new aircraft Mikoyan continued to develop its proposal as the LMFS “Light Multifunctional Frontline Fighter” which was designed to be smaller and more affordable. The programme requirements reflected the capabilities of Western fighter aircraft, such as the Eurofighter Typhoon and F-22 Raptor. The MiG 1.44 was subsequently cancelled and a new programme for a next-generation fighter, PAK FA, was initiated. Due to a lack of funds after the collapse of the Soviet Union, the MiG 1.44 programme was repeatedly delayed and the first flight of the prototype did not occur until 2000, nine years behind schedule.
Though not a participant in the MFI, Sukhoi started its own programme in 1983 to develop technologies for a next-generation fighter aircraft, resulting in the S-37, later designated Su-47. The subsequent programme designed to meet these requirements, the MFI “Multifunctional Frontline Fighter”, resulted in Mikoyan’s selection to develop the MiG 1.44. The project was designated the I-90 “Fighter” and required the fighter to have substantial ground attack capabilities and would eventually replace the MiG-29s and Su-27s in frontline tactical aviation service. In 1979, the Soviet Union outlined a need for a next-generation aircraft intended to enter service in the 1990s.
Its first flight took place on 29th January 2010. The aircraft is expected to have a service life of up to 35 years. The Su-57 is intended to succeed the MiG-29 and Su-27 in the Russian Air Force. The prototypes and initial production batch are to be delivered with a highly upgraded variant of the Lyulka AL-31 engine used by the Su-27 family as interim powerplant while an advanced clean-sheet design engine, the Saturn izdeliye 30, is currently under development. The fighter is designed to have supercruise, supermaneuverability, stealth, and advanced avionics to overcome the prior generation fighter aircraft as well as ground and naval defences. The Su-57 will be the first aircraft in Russian military service to use stealth technology.
Sukhoi’s internal name for the aircraft is T-50. The aircraft is the product of the PAK FA “Prospective Aviation Complex of Frontline Aviation”, a fifth-generation fighter programme of the Russian Air Force. The Sukhoi Su-57 is the designation for a stealth, single-seat, twin-engine multirole fifth-generation jet fighter being developed for air superiority and attack operations.
