The Su-57 is a large, twin-engine, fifth-generation stealth fighters with both air-to-air and air-to-ground capabilities.
The aircraft is reportedly designed for all-around stealth, meaning enemy radars should have difficulty picking up the jet from any direction, including the rear.
Like all fifth-generation stealth fighters, the Su-57 carries its weapons internally.
The SU-57 has two pairs of weapons bays. One pair is for short-range air-to-air missiles, while the larger pair is for long-range air-to-air missiles, precision-guided bombs, cruise missiles, or anti-ship missiles.
The Felon is also equipped with a 30-millimeter autocannon for strafing ground targets or aerial dogfighting.
