The Sukhoi Su-57 is a stealth, single-seat, twin-engine multirole fifth-generation jet fighter being developed since 2002 for air superiority and attack operations. The Su-57 is planned to be the first aircraft in Russian military service to use stealth technology. Its maiden flight took place on 29 January 2010 and the first production aircraft are planned to be delivered in 2020.
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 Lyulka AL-31 variant, the AL-41F1, as an interim powerplant while an advanced clean-sheet design engine, currently designated the izdeliye 30, currently in final stages of development and expected to be available after mid-2020s.
