I've decided to take my size comparisons to a whole new level. In fact, a whole new dimension... a third dimension. I've imported the game models and textures into 3D Builder and this allows for extremely accurate measurements of the ships. Unfortunately, there's only so many ships you can put in the same file without the program lagging out. Because of this, I'll have to do only a few ships at a time. I'll also only be doing ships that existed in real life to further reduce the size of the groups.
As requested, here is Iowa, North Carolina and Alabama
Note: The red shadow boxes under the ships represent the most extreme viewable dimensions
(Note: Ships are arranged by height from the bottom of the hull to the highest point on the mast and not from the bottom of the hull to the deck, although this point certainly still viewable in the picture)
(Note: Just like in game, these views arent entirely accurate because of camera favoritism. However, the red boxes under the ships remain accurate regardless so be sure to use them as a reference)
