Additionally, the two companies had differing design philosophies for the aircraft. Sukhoi's approach to the PAK FA competition differed fundamentally from Mikoyan's whereas Mikoyan proposed for the three design bureaus (Mikoyan, Sukhoi, and Yakovlev) to cooperate as a consortium with the winning team leading the design effort, Sukhoi's proposal had itself as the lead designer from the beginning and included a joint work agreement that covered the entire development and production cycle, from propulsion and avionics suppliers to research facilities. Further cost-saving measures include an intended size in between that of the Su-27 and the MiG-29 and normal takeoff weight considerably smaller than the MiG MFI's 28.6 tonnes (63,000 lb) and the Su-47's 26.8 tonnes (59,000 lb). Because of Russia's financial difficulties, the programme aimed to rein in costs by producing a single multirole fifth-generation fighter that would replace both the Su-27 and the MiG-29. Owing to the high costs, the MFI and LFI were eventually cancelled while the Russian Ministry of Defence began work on a new next-generation fighter programme in 1999, the ministry initiated the PAK FA or I-21 programme, with the competition announced in April 2001. Due to a lack of funds after the dissolution of the Soviet Union, the MFI was repeatedly delayed and the first flight of the MiG 1.44/1.42 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, eventually resulting in the forward-swept wing S-32 experimental aircraft, later redesignated S-37 and then Su-47.
Mikoyan was selected for the MFI and began developing its MiG 1.44/1.42. Two subsequent projects were designed to meet these requirements: the MFI (Russian: МФИ, short for: Многофункциональный фронтовой истребитель, lit.'Multifunctional Frontline Fighter') and smaller LFI (Russian: ЛФИ, Л short for: Лёгкий, lit.'Light'), with conceptual work beginning in 1983. multirole) by having substantial ground attack capabilities, and would eventually replace the MiG-29 and Su-27 in frontline tactical aviation service. The programme became the I-90 (Russian: И-90, short for: Истребитель 1990–х годов, lit.'Fighter of the 1990s') and required the fighter to be "multifunctional" (i.e. In 1979, the Soviet Union outlined a need for next-generation fighter aircraft intended to enter service in the 1990s.

Not counting prototype test aircraft, a total of 11 had been produced as of December 2022. After repeated delays, the first Su-57 entered service with the Russian Aerospace Forces (VKS) in December 2020. The first prototype aircraft flew in 2010, but the program experienced a protracted development due to various structural and technical issues that emerged during trials, including the destruction of the first production aircraft in a crash before its delivery. The aircraft is expected to succeed the MiG-29 and Su-27 in the Russian military service and has also been marketed for export. The Su-57 is the first aircraft in Russian military service designed with stealth technology and is intended to be the basis for a family of stealth combat aircraft.Ī multirole fighter capable of aerial combat as well as ground and maritime strike, the Su-57 incorporates stealth, supermaneuverability, supercruise, integrated avionics, and large internal payload capacity. Sukhoi's internal designation for the aircraft is T-50. It is the product of the PAK FA ( Russian: ПАК ФА, short for: Перспективный авиационный комплекс фронтовой авиации, romanized: Perspektivnyy Aviatsionnyy Kompleks Frontovoy Aviatsii, lit.''prospective aeronautical complex of front-line air forces'') programme, which was initiated in 1999 as a more modern and affordable alternative to the MFI ( Mikoyan Project 1.44/1.42). The Sukhoi Su-57 ( Russian: Сухой Су-57 NATO reporting name: Felon) is a twin-engine stealth multirole fighter aircraft developed by Sukhoi.
