Overview

The Sukhoi Su-57, designated "Felon" by NATO, is Russia's first domestically designed and produced aircraft marketed as a fifth-generation stealth fighter. Developed to compete with Western counterparts like the F-22 and F-35, the Su-57 is a twin-engine, single-seat, multirole aircraft intended for air superiority and deep-strike missions. Its development has been lengthy, and it has entered service with the Russian Aerospace Forces (VKS) in very small numbers. Its true stealth and sensor-fusion capabilities are a subject of debate among Western and Ukrainian analysts, with some characterizing it as a highly advanced 4++ generation fighter rather than a true fifth-generation platform.
