“Not than the Montana class”.
But they were never constructed.
Thank you for this information:
The Montana-class battleships of the United States Navy were planned as successors to the Iowa class, being slower but larger, better armored, and having superior firepower. Five were approved for construction during World War II, but changes in wartime building priorities resulted in their cancellation in favor of the Essex-class aircraft carriers and Iowa class before any Montana-class keels were laid.
I know but man they would have been something else especially with the 12 16 inch 50 cal guns that the Iowas had. With the radar control, heavier armor and weight of broadside they would have been frightening.
