Ansaldo pressed for the contract that became Bolzano, revealing how industrial and naval elites shaped procurement. Four turbines and ten boilers delivered roughly 150,000 shaft horsepower and the speed Italian planners wanted, while aircraft moved away from the bow hazard. Achieving the extra knots probably required roughly double the fuel consumption of the slower two-shaft arrangement. The ship remained lightly protected and later suffered repeated torpedo damage from Royal Navy submarines.
