A common mount matters only if industry can build it and yards can refit ships at scale. The Royal Navy's 1932-35 infrastructure programme under Third Sea Lord Reginald Henderson directed major spending into naval dockyards and private plants. Armour-making capacity is the clearest example because the same upgraded works later supported warship and tank production. Taking plants offline for modernization temporarily constrained rearmament, but doing that work in peacetime avoided a far more serious wartime bottleneck. The programme supplied the industrial capacity needed for fleet-wide standardization.

Interwar industrial investment makes mass refits possible
The ability to standardize a fleet weapon rests on the Royal Navy's early-1930s decision to revive dockyards and industrial plants left underused after the First World War.
