In China, they filmed the launch of missiles with a new rocket engine, with a deflected thrust vector. Judging by the video, the missiles change their flight path by 90 degrees almost instantly. At the same time, the missile moves at a huge speed. It is reported that the engine's starting acceleration can reach 2.6 Mach, and the maximum speed is from 16 to 20 thousand km / h. It is worth noting that it is possible that this is just computer editing.
