I had a play around and came up with something thats much more like a pocket battlecruiser. Armament consists of two duple 305/46 turrets fore and aft. Along the centreline between the funnels are 135/45 mountings that can fire to either side. Next to the 305mm turrets are the torpedo tubes, stacked quintuples. The large powerplant allows speeds of 33.5knts+. Armour is enough to fight cruisers.
