What would a 15-inch/50-caliber gun have changed?

A successful 15-inch/50-caliber weapon would have given the Royal Navy a heavier modern punch, especially with nine guns on the King George V class and refits for older battleships.

Question

How would development of the British 15-inch/50-caliber gun have affected the Royal Navy?

Short answer

It would have produced a much heavier battleship armament, particularly on a nine-gun King George V design and upgraded Queen Elizabeth-class ships.

Notes

The weapon would have value in both new construction and modernization. Nine such guns would make the King George V class markedly more powerful, while fitting the design to Queen Elizabeth-class ships could extend the benefit across the battle fleet. The answer reinforces the stream's earlier argument for common heavy-gun infrastructure.
