What would triple 4.5-inch turrets have changed on Tribal-class destroyers?
Short answerThey could deliver exceptional firepower, though the final layout would trade turret count and torpedo capacity against weight and space.
NotesThe proposed destroyer might use three rather than four turrets while retaining a formidable nine-gun battery. Dropping the fourth turret could leave room for two quintuple torpedo launchers, creating a different balance between gun and torpedo power. At a plausible twelve rounds per minute per gun, the two forward triple mounts alone could send roughly seventy-two shells per minute toward an opponent. Even imperfect accuracy would make that volume of dual-purpose fire extremely dangerous to enemy destroyers.
