Russia's fifth-generation Su-57 fighter jet took to the skies for the first time on January 29, 2010. The Su-57 is a multirole fighter designed to destroy all types of air, ground and naval targets. The Su-57 fighter jet features stealth technology with the broad use of composite materials, is capable of developing supersonic cruising speed and is furnished with the most advanced onboard radio-electronic equipment, including a powerful onboard computer (the so-called electronic second pilot), the radar system spread across its body and some other innovations, in particular, armament placed inside its fuselage. Compared to its predecessors, the Su-57 combines the functions of an attack plane and a fighter jet while the use of composite materials and innovation technologies and the fighter’s aerodynamic configuration ensure the low level of radar and infrared signature.
