Choosing shell weight or volume of fire

British cruiser and capital-ship choices show why gun calibre never settles the question by itself. Smaller shells can offer more salvos and more chances to range and hit, while larger shells promise greater effect when they connect. The Royal Navy's preference for 6-inch cruiser guns shows how rate of fire and likely engagement range could outweigh individual shell power. King George V was intended to carry twelve 14-inch guns, while the Lion, G3, N3, Nelson, and Rodney designs used nine-gun arrangements. A hypothetical British response to the Yamato class pushes the argument to an extreme: a very large ship with sixteen 16-inch guns would preserve both shell size and volume. The right balance depends on anticipated opponents, engagement conditions, and the tactical use of the ship's arcs.
