How much naval firepower would count as overkill in a sinking exercise against the older warship being discussed?
Short answerA contemporary Admiral-class ship is considered sufficient; Vanguard or a modern anti-ship missile supplies the deliberately excessive alternatives.
NotesThe target ship's name is unclear in the captions. The comparison begins with an Admiral-class ship of the same period as sufficient to destroy it. Extending the choice across eras brings in the battleship Vanguard and its radar-directed 15-inch guns. A modern anti-ship missile offers another way to attack beyond visual range. The insistence on avoiding a view of the target is a joke about its appearance.
