important part: The project of the latest version proposed the construction of an aircraft with a length of 50 m with a wing span of 40 m. According to calculations, the NX2 could fly at speeds up to 950-970 km / h at altitudes up to 12 km. It would also be possible to break through air defense at low altitude. The flight duration could exceed 24 hours, the range - at least 20-22 thousand km
there were also supposed to be multiple configurations of the plane if it was to be built but i dont thing those are rly important
