Drachinifel calls this proposed Dreadnought arrangement "Dread Lantern" because it stacked three twin turrets forward and three aft. It would have provided a twelve-gun broadside and the six guns firing ahead that Fisher wanted for a chase. The historical arrangement instead placed one turret forward, two aft, and one on each wing. Stacking so much turret weight high in the ship raised serious topweight and stability problems. The proposal would have increased the opening dreadnought standard substantially, but making the ship stable was a fundamental obstacle.
