Would 9.2-inch guns have made technical and logistical sense on a Royal Navy super-cruiser?
Short answerYes. The 9.2-inch gun was a well-established upper-end cruiser weapon that might have returned without treaty restrictions.
NotesA question about a Royal Navy super-cruiser places the 9.2-inch calibre in a longer design tradition. It was regularly used before the First World War and remained in service on some wartime ships. Without the naval treaties, it may have been a natural calibre to revive for large cruisers. The Orlando class's armament therefore sits near the later boundary between cruiser firepower and capital-ship weapons.
