An ridiculously large German battlecruiser: Ger/CB/1941 (Corrected)

Springsharp 3.0b1 does not prevent us from designing extremely large ships. This is the sort of ship that I had envisioned a long time ago, except that the armament here is lighter than I would have liked. Still, this is a 33 knot battlecruiser with good characteristics, so I would say that the design works well. The ship has 9-21in guns. This is the corrected Springsharp report:
