Why did the Royal Navy not adopt a Kitakami-style torpedo cruiser?
Short answerIt considered the idea, including an HMS Eagle conversion, but judged other capabilities more useful.
NotesAdmiral Bayly proposed converting HMS Eagle into an aircraft-carrying torpedo cruiser. British expectations about enemy tactics worked against the idea. Officers expected opponents to zigzag and doubted the value of sending a cruiser close enough for a mass torpedo attack. By comparison, Japanese assessments of American vulnerability drew on earlier experience and appeared consistent with American formations at Tassafaronga. The Royal Navy judged the torpedo-cruiser role a poor use of tonnage for its own missions.
