Completed Caracciolo-class ships could reshape the treaty battleship race

What would happen to world naval construction if Italy completed three Caracciolo-derived fast battleships by 1919?

They could trigger renewed European construction and push naval treaties toward controlled replacement building rather than a simple battleship holiday.

Three modern Italian fast battleships would signal that another Mediterranean construction cycle was beginning. France would resist being outbuilt by Italy, and Britain would avoid becoming the owner of Europe's oldest battle fleet. That pressure could keep the G3 programme alive while the United States and Japan pursued their own parity and budget goals. A treaty might therefore permit scheduled replacement construction instead of imposing a blanket battleship holiday. One illustrative alternative permits Britain and America five new capital ships per five years, Japan three, and France and Italy two, subject to an agreed total and service life.
