The shift to the three triple turrets was significant I think, along with the increase in speed and some loss of armor. Then you have the 5" 38 caliber secondary twin turrets all over the place, five on each side. When those were combined with proximity fuses ...
The first ship model I ever built was of USS
New Jersey. I was probably 10. I think I assumed that three triple turrets--two forward and one aft--was just the natural layout for main guns on a battleship.
Bismarck--with four twin turrets--was probably the battleship that made me realize otherwise.
The U.S. Navy didn't really like the idea of unequal armament at the ends of the ship. The "Standards" had all had equal main-gun armament at both ends (The
Colorado class had had four twin turrets of 16" guns). In trying to get the maximum-feasible number of 16" guns, it went to three triple turrets by necessity. The
Montana-class ships, had they been built, would have had four triple turrets of 16" guns.
The really goofy layouts for main guns were on HMS
Nelson and her sister-ship HMS
Rodney. Three triple 16" turrets, all mounted forward of the superstructure. Built under the provisions of the Washington Naval Treaty, they were an attempt to get maximum armament possible (to match or exceed the U.S.
Colorados) with reasonable armor and speed without exceeding the treaty limits.
