Asked about the state of development work of the Su-57’s unusual, truly fifth-gen engines, the deputy defense minister said it was too early to say at this stage. “factual now it’s hard to say, because there has only been one flight. Everything seems normal, but as you might imagine, this is a whole range of trials. Many test flights must be carried out. As a rule, such testing requires two-three years.”
Developed by Russian aircraft manufacturer Sukhoi, the Su-57 is designed for air superiority and attack roles, and plane is fitted with a revolutionary avionics system capable of autonomous calculations of the battlefield situation to assist the pilot.
The fighter is also equipped with airborne active phased array radar, which allows it to ‘see’ air, ground and naval targets at distances far beyond most modern systems, and to strike the enemy with a variety of modern weapons, including short, medium and long-range air-to-air, air-to-ground, and special anti-radar missiles. Built from composite materials, the supermaneuverable plane includes an in-flight refueling system.
