JB was originally designed to the Washington limit of 35,000 tons. That's standard displacement. Yamato's full load got up to near 72,000 tons.
Or just comparing standard displacements. JB was originally designed as treaty compliant battleship, therefore around 35000 tons. But, like all treaty battleshps, she grow weight as treaties expired and emerged closer to 40000 ton ship.
I had to post the max displacement of the Yammie too (but forgot sabout that ). 40.000t vs 64.000t standard or 49.850t vs 72.000t max
i used the standard displacement, nor the full load or max and i got that data from the book battleships of ww2 by m.j. whitely and no, i'm not confusing the richelieu class with the dunkerque class
