Was HMS Enterprise an impostor because her career did not match USS Enterprise CV-6?
Short answerNo. She was a real Royal Navy light cruiser with a good career; the comparison mainly reflects the greater fame of CV-6.
NotesHMS Enterprise was a capable light cruiser with her own service record. The confusion arises because many people know the American carrier but not the Royal Navy ship. Ship names recur across navies and eras. Identity is best resolved through the navy, ship type, and service history rather than assuming one famous vessel owns a name.
