The Ger/CB/1937 15 inch design (Revised)

I had made the mistake of arming this ship with 14in guns when it should have been 15in. That causes the ship to not do as well. The design attempts to give the ship a slightly heavier armament than the Bismarck on a smaller displacement. The freeboard is too low, but is what is needed to provide adequate composite strength. This is the Springsharp report:
