Historically armed with four-inch guns, the Abdiel class combined cruiser-like size with an official speed near 40 knots. In this scenario, the fast minelayers carry four or six 4.7-inch dual-purpose guns instead. Their ability to chase Italian cruisers or German E-boats in difficult sea conditions illustrates how a fleet-wide AA decision could also strengthen surface action. Commonality would affect specialized ships as well as destroyers and capital-ship secondaries.

Applying the common-calibre assumption to the very fast Abdiel-class minelayers produces a striking surface-warfare consequence as well as better air defence.
