ESSM is Mach 4+. China’s VLSes are bigger so I don’t see why a Mach 5 missile is out of the range of possibility.Got to say something about 555. 50km is attainable and so is 50G. But Mach 5 for a small missile? I need to call it doubts on this one. This could be a misinterpretation. Mach 5 is hypersonic. Could it mean it can intercept a Mach 5 target? Perhaps. Could it be a minimum engagement height instead, like 5 meters?
