The Royal Navy's effort to obtain effective 4.5-inch dual-purpose mounts explains why the Tribals retained 4.7-inch guns and why the Battle class used adapted capital-ship mountings. The Daring class could combine mature dual-purpose guns with more 40-millimeter weapons, torpedoes, and anti-submarine mortars. Those later ships required a broader weapon set because their threat environment had expanded and the technology had matured. The sequence treats these classes as stages of design evolution informed by wartime experience, rather than a simple hierarchy of good and bad destroyers.
