i really had idea for a tier X USN BB similar to this but first of all the guns would be in 2x2 2x3 or 5 guns on the bow and 5 guns on the stern for a unique design at tier X with 2.0 sigma and 243m disperison but with a slow shell velocity of 700mps
second the guns would also have a improved version of the USN CA pen angles .
third a unique feature for the secondaries is switching ammo types for certain occasions such as facing a broadsiding BB , CA , CL in close range .
fourth the main belt would be improved to be between 420mm-440mm the upper and lower belt would be 100mm thick. the torpedo protection would 65% on the midsection of the ship the bow and stern would be unprotected as most USN BBs are
