The US/BB/1927 design

This is a transitional design, in that the speed merits the ship's designation as a fast battleship. To achieve everything, the dimensions and displacement had to increase considerably. The deck armour was increased to 6in so as to better resist bombing and falling shot at long range. The main armament is now in triple turrets. The only reason that I can see that this is viable at the size it is, is that the range is quite modest. The short range (6,500nm at 15 knots) makes it less useful for Pacific operations. To achieve a 12,000nm range, I would expect that the size would need to increase dramatically. This is the Springsharp report:
