This one is a bit of an older one, but I did not post it here as it's also part of my AU, but I'll post it anyway. The Zao is one take on the proposed 1941 heavy cruiser design that was to be armed with 12x203mm guns. I fixed elements of the design that did not fit Japanese cruiser design doctrine, such as catapults/cranes and torpedo tubes at the stern, the fully enclosed 100mm mounts and updated the bow with the more modern clipper bow as seen on Oyodo and Agano classes.
Here's a another WoWS/semi-realistic design that was not posted due to being in the AU, the Azuma, ie the B-65 battlecruiser. Like with the Zao above, I fixed some elements that would not be present on the ship if built, such as the fully enclosed 100mm mounts. I did get some comments on the admirals bridge (and why the ship should not have one,) but I envision these as flagships of cruiser fleets, so the extra command space would be nice.
The third ship to appear here now due to being in the AU, the Hayate. Supposed to be a post-Shimakaze destroyer with true 127mm dual-purpose guns (in rather massive twin mounts) and a reduced torpedo carrying capacity of 2 quintuple launchers as opposed to three.
Not drawn specifically as a WoWS ship, but as an AU ship (later replaced with a British proposal) is the Almirante Cochrane, a Duca degli Abruzzi class cruiser as Wargamings take on the 1937 proposal for a cruiser to Chile. I touched it up by replacing some of the AA guns, boats and floatplanes with British equivalents.
This one is a new one; the Michelangelo. It's a cruiser/battlecruiser take on a battleship design that had the big guns amidships with cruiser-caliber secondary guns where the main guns normally would be. I did't really fix much with the design, other than consentrate all the 90mm guns amidships, and replace any and all sixtouple 20mm mounts with the more realistic twin mounts.
