Been a bit curious..... Iowa vs Yamato?

[http://www.navweaps.com/index_tech/tech-040.htm USN tests. 16" naval gun vs Yamato class armor plates]

It seams WW2 Iowa would shit her pants trying to pen Yamato's armor at normal distances, at which one would fire in a naval battle. Note that the plate in question was part of the turret armor, and it was shot at from close distance (less than 2 Km) with relined gun at an angle of 90 deg. In RL situation, this specific bit would be angled at 45 deg, making it inpenetrable for any WW2 naval gun (including Yamato's).

BTW to reach the citadel of Yamato-class BB, AP round at relatively horizontal trajectory, would have to pass through minimum of five layers of spaced armor, that makes for 3 air layers, and one water layer (water utterly shatters trajectory and velocity of any artillery round of that time expect the japanese T91 and T1 AP shells which were designed to partially overcome that effect. Today we deal with water by using cavitation-based ammo and torps). This armor is not unique to Yamato-class. Iowa herself had similary designed citadel armor.
