Do they need to be able to fight across the entire Pacific? Their most likely adversaries are right next door and their most likely ally is the dominant naval power already.
I any money spent on a large carrier would probably be better spent on other things. You can spend 10 billion on a single carrier or get a fleet of ~100 F-35s. I would guess mid-air refueling and more planes will get more sorties over likely targets in a conflict than a carrier would.
I also don’t think carriers are going to be the dominant sea power force in a future peer conflict. I think the submarine will dominate the next war. The carrier will be regulated to power projection after the sea is won and made safe to operate in.
