the biggest hurdle with a ballistic attack on a carrier is actually hitting them. they are constantly moving at 30 mph so even if you did launch, it would've traveled far enough in the 15 minutes it takes to hit to avoid it. hypersonics don't have a solution to this because terminal guidance is still a mostly unsolved problem. an affordable-issue missile with multiple vehicles and multiple sub vehicles is pretty much as good as it gets for saturating an area where a carrier could be.
