If Scharnhorst and Gneisenau had been sunk early

How would the Battle of the Atlantic have changed if Scharnhorst and Gneisenau had been sunk during the Norwegian campaign?

The surface-raider threat would have begun later and weaker, but British choices between battleships, carriers, and escorts would still shape the wider war.

In this counterfactual, Glorious spots and damages Scharnhorst and Gneisenau before heavier Home Fleet units destroy them. A visible success might have encouraged Britain to redouble its effort in Norway, although the scenario then assumes Norway is still lost. The early Battle of the Atlantic would face less surface-raider pressure, and Germany could assemble fewer dangerous surface task forces when raiding resumed. Britain would still have to decide how to balance battleships, carriers, and escorts. The submarine war remains central even when the surface threat changes.
