The Royal Navy repeatedly tried to create a universal gun for destroyers, cruisers, and capital-ship secondary batteries between 1920 and 1939. Those unsuccessful attempts left a complicated weapons inventory, but they also gave British designers the 5.25-inch option that distinguished Dido from ordinary destroyers. The U.S. Navy's more standardized approach reduced logistical complication and the need to fund additional systems. An imagined objection from Admiral Ernest King illustrates the supply burden of adding another weapon. Before the 5-inch/54 became available, that narrower choice left Atlanta with the 5-inch/38 and limited surface-fire advantages over a destroyer.

Universal guns traded experimentation for logistics
British experimentation produced more caliber choices for a screening cruiser, while American standardization simplified logistics but left Atlanta dependent on a destroyer weapon.
