Royal Navy destroyer development shows the same gap between an ideal requirement and an obtainable ship. A mature twin 4.5-inch upper-deck mounting would have suited the Battle class, but it was not ready when the destroyers were needed. The interim between-deck mounting drew on equipment normally intended for capital ships, and that choice also slowed carrier construction. An ideal Henderson-era design would combine four twin 4.5-inch mountings in a Tribal layout, two Daring-class torpedo batteries, and Battle-class light anti-aircraft weapons. Treaty limits and the need to build enough hulls made that all-purpose destroyer impractical, paralleling the compromises visible in France's battleship sequence.
