How might cruiser development change without interwar displacement limits?
Short answerHeavy cruisers would grow and perhaps adopt 9.2-inch guns, while fast six-inch light cruisers would still fill a separate role.
NotesGun limits could survive even if interwar displacement limits disappeared. Heavy cruisers might then grow toward 15,000-16,000 tons and possibly adopt 9.2-inch weapons. Six-inch ships would remain useful as smaller, fast cruisers with strong torpedo batteries. The result would be a clearer split between large heavy cruisers and light cruisers resembling enlarged destroyers.
