The limits of adding catapults to amphibious assault ships

Would catapults on large amphibious ships be useful for future European aviation ships?

Widespread adoption is doubted because deck catapults displace helicopter operations; shorter hangar-level launchers for drones remain a possibility.

Deck catapults consume space an LHD normally uses to launch helicopters. That is the main reason the answer doubts European and American ships would automatically follow China's approach. Different carrier and drone force structures can justify different arrangements. Shorter catapults firing drones from hangar level are offered as another possibility. The choice depends on what aircraft the force needs to launch and which deck functions it can give up.
