The other issue was speed. The Iowa class were designed to be "fast", able to keep up with the Essex-class aircraft carriers. Montana was reviewed and decided to sacrifice speed for much stronger armor. As the aircraft carriers proved to be much more important in the Pacific theater, the Montana plans were scrapped in favor of more Iowa-class which would be able to escort the numerous aircraft carriers also being built.
The Fog however, don't have this problem
at all, traveling an average of three times the speed of their WW2 counterparts (even underwater. Fucking Fog bullshit). Not to mention that Taylor doesn't have any requirements or limitations in terms of speed since there's no other Fog around to coordinate with. She'll probably be more concerned with firepower and armor, since capes like Alexandria, Legend, Siberian, Damsel, Scrub, etc. are scary physics-breakingly powerful.
Plus Taylor's got QA
