The alternative 1919 cruiser proposal chooses 4.7-inch secondary guns over 5.5-inch weapons. The choice explicitly uses hindsight about the Royal Navy's later destroyer standard. It is also linked to armament already appearing in the V and W destroyer development discussed here. A successful dual-purpose mounting for the cruiser is expected to have useful consequences for other ships, making the choice part of a wider armament program.
