![]() ![]() 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 ( Russian: ЛМФС, Russian: Легкий многофункциональный фронтальный самолёт, Liogkiy Mnogofunktsionalniy Frontovoi Samolyet, "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 ( Russian: МФИ, Russian: Многофункциональный фронтовой истребитель, Mnogofunksionalni Frontovoy Istrebitel, "Multifunctional Frontline Fighter"), resulted in Mikoyan's selection to develop the MiG 1.44. The project was designated the I-90 ( Russian: Истребитель, Istrebitel, "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. Main article: Post-PFI Soviet/Russian aircraft projects Its first flight took place on 29 January 2010. The aircraft is expected to have a service life of up to 35 years. 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 Su-57 is intended to succeed the MiG-29 and Su-27 in the Russian Air Force. 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 ( Russian: ПАК ФА, short for: Перспективный авиационный комплекс фронтовой авиации, romanized: Perspektivny Aviatsionny Kompleks Frontovoy Aviatsii, lit.''prospective aeronautical complex of front-line air forces''), a fifth-generation fighter programme of the Russian Air Force. The Sukhoi Su-57 (Russian: Сухой Су-57 NATO reporting name: Felon) is the designation for a stealth, single-seat, twin-engine multirole fifth-generation jet fighter being developed for air superiority and attack operations. ![]()
