How might American and Italian cruiser design respond to a British 9.2-inch County-class cruiser?
Short answerThe United States would probably adopt the same calibre, while Italy would work toward its own equivalent more slowly.
NotesA lightly protected Pensacola with twelve 8-inch guns is treated as a possible American reply, though it would be an awkward one. If 9.2 inches became the treaty limit, the United States would more likely build a 9.2-inch design of its own. Italy would probably answer more slowly with an equivalent cruiser when its industrial program allowed. The exchange shows how a new calibre limit could redirect several navies without producing identical ships.
