Would steam catapults improve US carriers in 1941?

Early steam catapults would support heavier aircraft but might slow the rapid deck-run launches that put large Second World War strike groups into the air.

Question

Would focusing on steam catapults by 1941 make US carrier operations more effective?

Short answer

It would enable heavier aircraft but could slow mass launches and require major structural changes, so the wartime benefit is uncertain.

Notes

Steam machinery requires stronger decks, extensive piping, and design work that cannot simply be added to a wooden-topped carrier. The gain is the ability to launch heavier aircraft as aviation develops. In 1941, however, carriers could roll light aircraft off the deck every few seconds, while catapulting them sequentially might reduce sortie speed and the number available to score hits. The answer demonstrates that a more powerful launch system is not automatically better for the aircraft and tactics of an earlier period.
