One possible E-class development placed one twin 6-inch turret forward and two twin turrets aft. The three mountings would put six guns on either broadside. That matched the effective broadside of Enterprise's mixed battery, which combined a twin mounting with centreline and wing-mounted single guns, rather than simply adding more weapons. The comparison separates turret arrangement from raw firepower and shows why deck layout mattered to the evolutionary exercise.

Three twin turrets could preserve a six-gun broadside
A one-forward, two-aft twin-turret arrangement could match Enterprise's existing six-gun broadside while distributing that firepower differently.
