I'm still looking at this design and wondering if I should leave it be, as is, or if I should have it converted over to being a carrier. If so before or after it was completed, if it was before then I imagine much of the armour would be gone, but after would perhaps be more realistic. So what do you think guys?
As for why it exists this is basically the result of the cruiser section of the MSDF being more and more unable to keep up with the crusing speed and distances of the battleships. In order to compensate the Sanamel Design Agency decided to create a Large Cruiser, in keeping with the idea that this was a cruiser and not a battleship with poor armour they stuck with 12 inch guns. The resulting design was and is quite controversial, almost immediately certain factions of the Maritime Self-Defence Force wanted to convert it into a carrier, while others wanted to build even more.

Is there someone playing Italy by the way? Because I'll be using Italian school designs later in the game (1930s).
(and to be honest, I can't think of many Greek names off hand being not Greek.)
