Closing viable shipyards left the government struggling to retain capacity. In this counterfactual, regular cruiser and sloop orders keep firms, skilled workers, armour makers, and armament producers active while lowering the risks created by industrial monopoly. That industrial base would also give Britain more escort hulls at the opening of war and reduce reliance on emergency programmes such as the Hunt-class destroyers and Flower-class corvettes. Those programmes might still proceed, but they would expand a fleet that already had more escorts in the water. More escorts available from the outset could challenge the early U-boat wolf packs before they reached full strength. The larger industrial base could also accelerate capital-ship, aircraft-carrier, and aircraft procurement during rearmament.

Shipbuilding capacity as rearmament insurance
Maintaining a baseline of naval orders would preserve skilled labour and suppliers, making later wartime expansion faster and less fragile.
