I think the speed is more in regard to the capability to go into space. From what I remember, the SR71 was easily fast enough to go, but the limit was atmosphere (engines). If they could get something into space that could come back as a single unit (needing just a refuel), it could change a lot. Total speculation though, it's probably just super fast so it can go destroy other humans super good, because that's super important.
