The monster battleship Ger/BB/1943

The Ger/BB/1943 monster battleship is the battleship analog of the Ger/CB/1943 design. The battleship has a speed of 29 knots and carries 12-22in guns. The armour basis is 22 inches with a 10 inch deck. I don't believe that the ship would really resist 915.4 torpedoes, but that is what Springsharp 3.0b1 claims. This is the Springsharp report:
