Somehow I doubt that Stealth technology, as a overall concept, overlaps at all with Hypersonic weapons technology. Anything moving that fast is generating a lot of eat as well as a pressure wave (noise).
Anything flying Mach 3 or better is also going to be operating at very high altitudes — not on the deck where today’s ship killing weapons tend to operate. Maybe a hypersonic could do a terminal low-level pass, but the margin of error for obtaining a hit gets a little dicey at those speeds. If youre off even a fraction of a degree on your approach vector you could miss by a significant margin.
Nevertheless the technology keeps advancing. The question is can these ships defend from the different types of missiles and drones and survive. For instance suppose a distant submarine launches a cruise missile which is loaded with hundreds of small “seagull” stealthy drones packed with C4 plastique programmed to swarm a huge carrier about to launch fully armed and fueled planes? IMHO these big surface capital ships are big targets for clever weapon designers. Not sure the defensive systems can stay ahead of the offensive weaponry.
Maybe those Navy laser tests aim to decoy a missile’s terminal guidance lock. Might also be capable of creating gremlins that appear to demonstrate impossible maneuvers.
