Was the Royal Navy planning a second Tiger-class battlecruiser named Leopard?
Short answerNo British estimates or archival evidence support the claim, and Siegfried Breyer's unsupported name may derive from German intelligence or speculation.
NotesTiger's successor would belong to the next naval program, but neither British estimates nor other historians' archival work confirms Leopard. The same source problem affects claims that N3 battleships would be a Saint class: the ships had not yet reached the naming committee, and the proposed style was culturally unlikely for the Royal Navy. Dreadnought is a more plausible name for ships intended as a major restatement of the battleship concept. That suggestion remains informed speculation rather than a documented naming-committee decision.
