Would a Hood modernized to 2022 standards remain active or become a museum ship?
Short answerActive service, at least initially: its speed, huge VLS capacity, and prestige would make it a valuable flagship.
NotesModern gas turbines would combine Hood's large hull and speed potential with reliable contemporary propulsion. Extensive VLS and close-in defenses would turn that volume into substantial missile capacity. The ship would therefore remain in active service for at least several years. Her combat utility and prestige would make her an unusually visible Royal Navy flagship rather than an immediate museum.
