An even larger Ger/CB/1943 battlecruiser
The only advantage to what I am calling the Ger/CB/1943 design is that it has a 14in belt and main armament protection. One of the 12in belt Ger/CB/1942 designs could reach 37 knots. This can comfortably reach 35 knots, and has a 9,000 nm range at 15 knots. This is the Springsharp report:
