speed or cruse speed of some plane can be calculate with 80% precise if u know specs of engines, boddy weight,wings specs ,aerodinamics and ... now way that plane with jets which give 49kn trust can supercruse at 1.8 mach. Max speed can be 1.8 mach but supercruse no way. I dont believe that this mitsubishi x2 can cruse with more than 1.2-1.4 mach with maximum settup of engines which can lower there life a lot. Please check that or find better info.
