Wow, that is great news!
What "hypersonic missile" was used to test and validate this new capability? Surely it was tested against some hypersonic missile acting as a target. Maybe this system was tested against ARRW and prevents booster ignition?
Or was this actually a "simulated capability" against a "simulated missile" ? Because if this is the "classified capability" I think it was, yes that's actually what happened. Which is like saying that we now have "capabilities" that were validated in Call of Duty.
