A GB/BB/1908 design study

This specification appears to be for a ship that was intended to give up speed and armament to achieve good protection. The hull is flush decked and there are two triple 12in turrets, one at either end. There is a complete belt, 14in amidships and 6in at the ends. The deck armour is 4in. The design has so much excess capacity that a speed of 26 knots can be achieved. This is the Springsharp report:
