The
Sukhoi Su-57 (
Russian: Сухой Су-57)
[13] 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 aeronautical complex of front-line air forces''), 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,
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.
