Sukhoi Su-57 T-50 - PAK FA stealth, single-seat, twin-engine multirole fifth-generation jet fighter The Sukhoi Su-57 (Russian: Сухой Су-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 (Russian: ПАК ФА, short for: Перспективный авиационный комплекс фронтовой авиации, translit. Perspektivny Aviatsionny Kompleks Frontovoy Aviatsii, lit. '"Prospective Aviation Complex of Frontline Aviation"'), a fifth-generation fighter programme of the Russian Air Force. Sukhoi's internal name for the aircraft is T-50. The Su-57 will be the first aircraft in Russian military service to use stealth technology. The fighter is designed to have supercruise, supermanoeuverability, stealth, and advanced avionics to overcome the prior generationfighter 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 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.
