How would Germany, Italy, and Japan react to a Royal Navy fielding about 137 cruisers?
Short answerThey would face almost twice the planned British cruiser strength, with far greater global presence and many more ships to counter.
NotesThe proposed class totals add up to 137 Royal Navy cruisers, almost twice the interwar plan for about seventy. A force of that size would make British sea power far more visible around the world. Germany, Italy, and Japan would have many more British ships to track and counter even without assuming that every cruiser was individually superior. The strategic advantage comes from fleet density and global availability.
