An 18-inch Revenge class would favour six guns and speed

What would the Revenge class become if the Queen Elizabeth class already carried 18-inch guns at 28 knots?

Probably a 28-knot, six-gun development that preserves the basic layout without paying for a much larger eight-gun ship.

The Revenge class would be the less expensive continuation of the altered Queen Elizabeth design rather than a wholly new departure. Four twin turrets would demand a larger, costlier hull, so six 18-inch guns are more likely. A return from 28 knots to 21 knots also seems unlikely, making a fast six-gun ship the probable compromise.
