Was HMS Courageous originally a battlecruiser?
Short answerThe Admiralty called Courageous, Glorious, and Furious large light cruisers, an unusual Fisher-era category that included an 18-inch-gun concept.
NotesCalling Courageous a battlecruiser misses the Admiralty's more specific label. Courageous, Glorious, and Furious were classified as large light cruisers. Fisher's idea of fitting an 18-inch gun to a light-cruiser concept shows how unusual that category was. The official term carries a historical meaning that a later visual comparison can obscure.
