A really super heavy cruiser for 1923

I am not sure what to think of 10in guns on a heavy cruiser, but I tried them on a 1923 design to be built if there were no Washington Naval Treaty. This is another flush-decked ship with triple turrets for the main armament. The armament in this case is like other 1923 ships, in that it is the start of a modern approach with DP guns for the secondary armament. The armament is 9-10in BLR, 8-4.7in DP, and 36-2pdr AA in quad mounts. There are no torpedo tubes. The armour basis is 6in with a thick 3in deck. There is also a 1in torpedo bulkhead. The range has grown to 7,500nm at 15 knots. The maximum speed has moved up to 33.5 knots, thanks to the transom stern. This is the Springsharp report:
