What type of ship now marks a navy as a major or regional power?
Short answerCapable amphibious ships are a stronger modern indicator than battleships because they turn sea power into supported action ashore.
NotesPossessing battleships once signalled membership among the world's major powers. For a modern navy, capable amphibious shipping is a more useful indicator. Such vessels reveal whether a state can carry forces, support them, and connect maritime power to action ashore. This is a compact measure of reach rather than a complete ranking of naval strength.
