Britain's next capital ship after the G3 and N3 classes had not yet become a settled design. An 18-inch fast battleship is plausible, and a 16.5-inch alternative also fits the direction under discussion. The Royal Navy was still waiting for trials, policy decisions, and experience from the ships already planned, so contemporary officials could not know the final answer themselves. Later reconstructions can propose likely paths, but certainty exceeds the surviving evidence.

British plans after the G3 and N3 classes were still fluid, so later claims of a definite successor design should be treated cautiously.
