My Ger/BB/1942 very large battleship

I have a very large battleship design for the Germans from February 1999. I like my specifications for Springsharp better than what I had thought valid in 1999. The sketch is for a 115,000 ton ship of 31 knots with a 17in armor basis and 9-21in guns. My take on this is that it cannot be as good as Springsharp says. Otherwise, we would have built fleets of them. This is the Springsharp report:
