The Italian project moved from four triple turrets to five twins and finally four twin 15-inch turrets so that speed, armour, and torpedo defence could coexist. That reduction in gun count was a deliberate exchange, not evidence that the concept had failed. The resulting 28-knot ship would have combined decisive mobility with the protection needed to stay in a fleet action, making Francesco Caracciolo an early fast-battleship benchmark. In this counterfactual, even limited completion could have accelerated French and British responses and given later Italian designs a much stronger starting point.
