A peacetime 1942 Royal Navy under Reginald Henderson

What might a peacetime 1942 Royal Navy led by Henderson have looked like?

It would likely be a substantially more modern carrier-centered fleet with fast battleships, more six-inch cruisers, and many additional large destroyers.

This counterfactual fleet is farther through Henderson's twelve-year transition. Armored carriers would serve alongside Ark Royal and Unicorn, producing as many as eight usable flight decks, while fast battleships assumed battlecruiser roles. More modern six-inch cruisers and perhaps two or three additional flotillas of large destroyers would deepen the screen and scouting force. By 1942, the navy would be three-quarters through modernization instead of the halfway point reached when war began in 1939. A later follow-up adds that Henderson's standard destroyer would probably adopt 4.5-inch dual-purpose guns earlier, with the Tribal class prepared for a retrofit.
