|I've definitly heard the debate between the Navy and the Marines concerning the fate of the Iowa Class Battleships. The Marines love the Sixteen inch guns, the Navy hates the battleships. They claim that its too much money, too much vessel, too much maintenance, and too much trouble. The marines look at the guns currently mounted on the Arliegh Burkes, Ticonderogas, and Zumwalt class boats, and (Just like your exe)says "Looks a little small to me." So heres my crazy, probably not logical idea for a solution.
Why not highjack the turrets from the BBs, and mount two of them on a new hull? Something vaguely similar to the Admiral Sheer style pocketbattleships that the Germans deployed during world war two. All she really needs would be her two turrets, some drones for artillery spotting, and possibly a CIWS system for selfdefense.
The marines keep thier fire support. The Navy doesn't have some giant WWII relics to maintain. I imagine two of these vessels, one in the pacific, and one in the Atlantic. These two boats are specifically act as an interem design until new systems come along that can sufficiently replace them (IE the electromagnetic railguns that the navy is currently experimenting with.)can replace them.
