The Schlesien class will have excellent gunnery. From what I have read, German fire control was excellent in both World Wars. I think a vessel of the Schlesien class will be a match for just about any cruiser in any navy.
This thing is basically an Alaska class battlecruiser tossed in a blender with a Scharnhorst. A bit bigger than a Des Moines. Over 800 feet. Im looking to make 35 knots.
I think I'm going to put this ship on hold for awhile. I'm going to start on the cruisers for now. But I promise I will come back the the Bayern modernization.
