the Mig 1.44 was a delta wing, twin-tailed, fifth-generation air superiority/strike fighter design that incorporated advanced technology to theoretically give the aircraft excellent stealth and fighting attributes. It featured a close-coupled canard layout which, when working with the vectorable engines, gave the aircraft remarkable maneuverability. The aircraft had a tricycle landing gear system, with a single, dual-wheel landing gear in the front, and two single wheels in the rear. The MFI had relaxed stability and was controlled by a fly-by-wire flight control system
Russian aviation experts claim that the unorthodox design, use of radar-absorbent materials (RAM), and internally mounted weapons, gave an radar cross-section (RCS) of less than 0.3 m2, comparable to that of the F-22 Raptor. The RCS falls to 0.001 m2 with the use of a plasma shield.
Two Lyul'ka Saturn AL-41F afterburning turbofans produced 177 kN of thrust, giving the MiG a top speed of Mach 2.35. The engines also allowed the jet to supercruise.
The fighter is equipped with a glass cockpit and features a Pulse-Doppler radar. The N014 radar, with a range of 420 km (260 mi) and target detection from 250 km (160 mi) to one metre (3.3 ft), was able to track up to 40 targets and shoot against 20. The radar system has a passive electronically scanned array antenna and is linked to a fire-control system.
