The GB/CA/1921 New Armoured Cruiser (Updated)

This is my current concept for a British 1921-style armoured cruiser. Since the battlecruisers will be carrying larger guns, the armoured cruiser can use the 12in/50 gun. This is the updated Springsharp report which includes a range, which had been inadvertently omitted:
