Would a hull like USS Ranger make a good amphibious assault ship?
Short answerNo. Its stability and construction posed problems, and a more robust carrier hull such as Wasp would be a better starting point.
NotesAn amphibious assault conversion needs a stable and strongly built hull with room for aviation, troops, boats, stores, and command facilities. Ranger's light construction and design compromises made it a poor foundation for that combination. The conversion would spend heavily to correct limitations already built into the ship. A sturdier carrier such as Wasp offered a better starting point for the same exercise.
