How would 1942 change if USS Wasp continued serving with Force H?
Short answerThe largest effect is doctrinal: Wasp adopts British continuous combat-air-patrol and ASW practices while becoming unavailable for the Pacific.
NotesThe reply distinguishes Wasp's Malta ferry operations with Force W from the proposed continued assignment to Force H. Remaining there would expose her to the most demanding convoy battles. British practice would keep fighters continuously rotating over the force rather than preserving them mainly for strike missions. Other aircraft would emphasize reconnaissance and anti-submarine patrol to maintain a protective air umbrella around the convoy. This may not transform the whole theater, but it accelerates American experience with British carrier-defense methods and keeps Wasp out of the Pacific, increasing the earlier need for British carrier support there.
