What ship name should the Royal Navy have used but, to your knowledge, never did?
Short answerThunder Child is the leading fictional choice, while Pendennis Castle was ordered for an uncompleted wartime corvette.
NotesThunder Child, the fictional warship from The War of the Worlds, is the first choice for a strong name the Royal Navy has not used. A search then turns up Pendennis Castle as another attractive candidate. The service actually ordered that name for a Castle-class corvette in 1943, but the ship was never completed. The distinction shows why an assigned name can appear in records without ever entering the active fleet's commemorative tradition.
