What might a modern Royal Navy heavy cruiser look like if the type had been retained?
Short answerIt could carry forward-mounted twin autoloading 8-inch or 9.2-inch guns backed by Mark 41 vertical-launch cells.
NotesThe proposal uses two twin autoloading mounts forward, firing either 8-inch or 9.2-inch guns. Mark 41 VLS would provide the missile battery. That is the suggested alternative to the question's triple 6-inch armament for a Royal Navy that had retained heavy cruisers.
