Why Italian cruisers used British boilers and turbines

Could Italy not build its own cruiser boilers and turbines?

Not always to the desired standard and schedule; infrastructure gaps led prestigious Italian projects to rely on established British machinery suppliers.

Industrial capacity and specialist maritime engineering did not advance evenly across every component. Italy preferred proven British boilers and turbines over French alternatives it distrusted and American suppliers it did not want to use, creating a continuing dependence for parts and technical knowledge.
