Could very large ships, including carriers or battleship-sized hulls, make at-sea missile reloads more practical?
Short answerLarger hulls make reload and magazine arrangements more plausible, which is why modern debates often jump from destroyers and frigates to much larger ship concepts.
NotesReloading a vertical launch system (VLS) at sea raises questions about hull size and weapons handling. A carrier or a battleship-sized hull offers a possible route because of its scale, although placing cells above existing magazines also raises a question about weapon flow. The argument favours larger ships than many recent frigates and destroyers for this role. One proposed explanation for jumping directly to the battleship label is that cruiser terminology carries unwelcome imperial associations. Modern surface ships nevertheless retain many traditional cruising missions in peacetime. The gunboat-diplomacy example connects those missions with the pressure exerted by a large ship carrying more guns. These are arguments for considering larger vessels, without a worked design or VLS cell count.
