The 65,000 ton, 18in gunned version of the Ger/BB/1916 design

This is the version of the Ger/BB/1916 design that has 9-18in guns, 24-5in QF guns, and has a 65,000 ton Standard displacement. The hull is flush-decked, with a high freeboard and flared bow. The protection is expansive, having an 18in armour basis, but is less than the 34,663 tons that I had originally specified. The difference seems to be in that I have put that into the machinery, so that the ship has a 27.5 knot speed. This is the Springsharp report:
