Battleship Design A-55

I soon finish drawing these preliminary designs as I run out of useful data but now I show you this variant.

What is known about this design that it's length 173,7meters, same as the Design A-49, 27.300tons displacement, 44.000shp engine power and 12x 30cm cannons in 6 twin turrets.
Despite the absolute similarity with the final Fuso design there are some differences:
The length is 30meters short (202.7m was the Fuso), 2000tons less displacement, armament aren't 36cm but 30cm cannons and as the secondary armament aren't stated I've used the earlier 12x1 152mm Casemate guns (Fuso had 16 such guns), and lastly the engine power is 10% stronger (40.000 on Fuso)

So this could be seen as probably the smallest hull where you can place 6 twin turrets on the centreline in this arrangement.
