Battleships as peacetime presence and conflict-management ships

A battleship had peacetime work: it trained, hosted dignitaries, served as a flagship, and visibly demonstrated that its state could afford a ship built for high-end war. Its marines, band, advanced equipment, and visibly proficient crew all contributed to the diplomatic message delivered during a port visit. A carrier's escorts, embarked F-35s, and airborne early-warning support form part of its combat system, whereas a battleship was expected to deploy alone. That made the battleship one step in an escalation ladder from a sloop or destroyer through cruisers to a capital ship. Modern fleets have fewer ship types and spare hulls, so sending a frigate can communicate less resolve than intended while sending a carrier group may communicate too much.
