Early adoption creates time to fit the weapon across destroyers, older ships, cruisers, and possibly escorts before wartime demand fragments production. Town-class cruisers and older ships fitted historically with twin 4-inch weapons become candidates for the more capable dual-purpose battery. Concentrating factories on fewer calibers would improve output and ammunition commonality. The wider change is a fleet-wide industrial and logistical shift before the Second World War, with the improved Tribal class as its first visible result.

A ubiquitous British dual-purpose gun
Starting production in the early 1930s could make the 4.5-inch gun Britain's widely fitted counterpart to the US Navy's 5-inch/38.
