Not true. Iowas are another generation in ship design, their w/t compartments scheme is different, armor thickness, hull design, and immunity zones are quite different. Her design played off the errors learned on the NC and the SoDak. As far as a first generation post Washington treaty ship goes, NC is a very conservative approach, especially when compared to her true contemperies, like Bismark and Yamato. I am only talking of the hull form, from where I stand Yamatos hull form is ahead of even Iowa.

They weren't so much errors to be played off, but rather points to expand upon, after treaty limitations were lifted. Remember that the US had no real interwar design experiences before the
NC (except for the converted
Saratoga and
Lexington battlecruisers), unlike the British, who had begun their next generation with
Nelson and
Rodney, more than a decade earlier.
As to their armor protection, only the
area involved was significantly different between
SoDak and
Iowa, not the thickness, and the truth is closer to Werner's version, than to any notion that
Iowa was a "new generation". In fact, even
Iowa's 16"/50cal guns were based on a 1920's design and, although a superior weapon to the 16"/45cal of the
NC and
SoDak classes, the
Iowas required a significant turret and mounting re-design, just to fit their barbettes into the ships!
Being laid down less than 1 year after
SoDak's hull,
Iowa could not have benefited too greatly from her, either---the design plans were too far along for major changes by then, at any rate.
SoDak and
Iowa were siblings somewhat apart, but definitely the same generation.
