How saving Courageous could reshape later carrier operations

What wider effects might follow if tenders kept Courageous and other fleet carriers out of early ASW patrols?

More surviving carriers and experienced crews could strengthen Norway, Taranto, and later fleet operations, though the exact chain is highly uncertain.

If a tender system replaced Courageous in submarine hunting, Courageous might survive to operate with Glorious in Norway. Two carriers, a senior flag officer, and airborne reconnaissance would improve their chance of detecting or avoiding the German battlecruisers that historically caught Glorious. More surviving decks could reduce wear on Ark Royal and support a larger strike at Taranto. By late 1941, surviving Courageous and Glorious might also be available to accompany Force Z. Preserved aircrews and damage-control specialists could also spread their experience through the growing Fleet Air Arm. These are cumulative butterfly effects rather than a single predictable chain. More available options generally improve the least-bad choice open to commanders.
