How would 9.2-inch County-class cruisers change Denmark Strait, Java Sea, and Indian Ocean raider actions?
Short answerThey would be stronger and perhaps more survivable, but opponents would adapt and the ships would still face broadly similar missions.
NotesA larger County-class cruiser with 9.2-inch guns would have more striking power and could carry better protection. That improvement does not guarantee a different outcome at Denmark Strait, Java Sea, or on commerce-raiding patrols. German and other foreign cruisers would probably answer the new caliber, potentially with their own 9.2- or 10-inch weapons. The ships would also still be assigned to the roles for which they were built, so operational context remains as important as gun size.
