India को Russian SU-57 क्यों खरीदना चाहिए? | Why India Should Buy SU-57?

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. The aircraft is the product of the PAK FA, a fifth-generation fighter programme of the Russian Air Force. Sukhoi's internal name for the aircraft is T-50. The Su-57 is planned to be the first aircraft in Russian military service to use stealth technology.

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 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 an interim powerplant while an advanced clean-sheet design engine, the Saturn izdeliye 30, is currently under development. The aircraft is expected to have a service life of up to 35 years. Its first flight took place on 29 January 2010.

In 1979, the Soviet Union outlined a need for a next-generation aircraft intended to enter service in the 1990s. The project was designated the I-90 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. The subsequent programme designed to meet these requirements, the MFI, resulted in Mikoyan's selection to develop the MiG 1.44. 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. 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. The MiG 1.44 was subsequently cancelled and a new programme for a next-generation fighter, PAK FA, was initiated. The programme requirements reflected the capabilities of Western fighter aircraft, such as the Eurofighter Typhoon and F-22 Raptor. 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 which was designed to be smaller and more affordable.
