Why six-inch cruisers could overwhelm eight-inch rivals

Interwar Royal Navy cruiser studies provide a smaller-calibre parallel to the Incomparable problem. A large six-inch cruiser could fight at much the same practical engagement range as an eight-inch cruiser while delivering a far greater volume of fire. The smaller weapon also allowed more ships on a given total tonnage and simplified worldwide support. Six-inch ammunition was heavy but still within the limit that people could move when machinery was unavailable, whereas eight-inch ammunition imposed greater handling demands. The comparison links combat effectiveness to fleet numbers and logistics instead of treating calibre as an isolated measure of power.
