The penetration ratings are based on homogeneous armour, and are reduced for layered armour belts such as those used in the Iowa class BB. Those ships use 3 differant layers of armour on the main turrets, and all vital areas have at least a 2 layer armour scheme to make penetration harder. The armour has an outer case layer, the core layer, and a splinter layer to prevent spalling. Everything's angled too which makes the effective thickness greater than the specs, which are measured perpendicular to the armour face.
Correct, however the differance in resistance is insufficent to matter. Splinter protection is not going to stop the blast of a shaped charge and in the case of turrets and the CT, to close to the main armor to make a differance. If you shoot a ATGW at say the belt, it wound;t matter even if there was no armor beucase the warhead jet would run out of steam before reaching anyhting important.

As for the 155mm shell, it may have more range than a 16/50, but how much damage can it cause? I doubt it could really damage anything larger than a PT boat. Using a 155 against ships is kinda like shooting a tank or APC with a m16, it'll take a ton of shots or a lucky hit to stop the target. I can easily pick up a 155 shell, while a 16/50 shell weighs more than a small car and is longer than I am tall, I wonder which'll do more damage.
Six inch and below shell fire sank more ships when all guns above it in WW2..
You might notice that Guns between 150 and 155mm where the most common main battey of cruisers with a majority, and mounted by scores of of battleships and battlecruisers as secondarys.
Many cruisers fell to 6 inch gunfire, and several battleships and battlecruisers suffered heavy damage from such fire.
One 16/50 gun might do more damage then a 155mm, but for the weight of a triple 16 inch turret you can have twenty automatic 155mm guns which will deliver about 65% more weight of shell. You can also engage multiple targets over a wide area with them at the same time.
You can also use such guns much closer to your own troops. 16/50 can't be used for anything like close support, and as a result is worthless for the most important of fire missions.
For wipe spread area damage, rockets have tube artillery beat already, the USN really should buy POLAR.
