But SoDak, you have GLORIOUS RELATIVE ARMOR of 18 inches if that bit was believed. Remember you got Kirishima whack the shit out of you and still was combat effective afterwards when you came back from port.
South Dakota still have treaty limits all over her (though some of that was just Congress was only willing to fund 35,000 ton battleships at that time), but was designed to fight someone who also had 16 inch guns and to carry 9 such guns herself. Smaller ships, heavier armor.
North Carolina and Washington were London Treaty designed to carry quad 14 inch guns, but had the option to mount triple 16 inch gun turrets in case Japan backed out of the Second London Treaty, but was designed to fight lighter ships also armed with 14 inch guns.
Iowa was built with the treaty having ended and Congress on board to do some high speed damage, while still fitting in the Panama Canal.
