Mach 5 in a manned fighter? Where is the proof?
Their is very little information available about this weopon in public, even if its tested we might never know. The only thing we can do is wait until more info comes out.
But I can tell you one thing for sure, even if the US has a lead in this technology it is very narrow.
didn't soviets have a considerable lead with the hypersonic Kh-90?Americans bought russian MGD Pamir ZU for their ghypersonic weapons...
