The T-50 is Sukhoi's internal name for the prototype, developmental and pre-production test aircraft of the fifth-generation Su-57 fighter. The aircraft is a single-seat, twin-engine, fighter designed for air superiority as well as ground attack and will be the first operational aircraft in Russian service to use stealth technology. The Su-57 is intended to succeed the MiG-29 and Su-27 in Russian Air Force service. This T-50 example was pictured as part of the flying display at MAKS 2013.
