The preferred compromise between guns, torpedoes, speed, and stability depends on the navy and mission. The Royal Navy's gun destroyer is expected to cover some duties otherwise assigned to light cruisers. In the game, ten 5-inch guns in five twin mounts create an intentionally gun-heavy answer to that requirement. The result resembles a destroyer-sized Dido, one answer to a Royal Navy force-structure problem rather than a universal optimum.

Destroyer balance depends on the navy's mission
The Royal Navy's desired gun destroyer could undertake some light-cruiser work, but another navy's mission would produce a different balance.
