Ten-gun Queen Elizabeths at 28 knots

How would ten 15-inch guns and a speed of 28 knots change the Queen Elizabeth class?

They would become true fast battleships, able to match many battlecruisers while keeping a heavily armed battle line together.

A ten-gun battery and 28-knot speed would push the class beyond the historical super-dreadnought standard. The ships could keep pace with many foreign battlecruisers while retaining battleship protection and firepower. Britain would gain a fast battle line instead of having to separate speed from heavy combat power. Other navies would have to answer a class that combined qualities they had expected to face in different ship types.
