Project history

Ordered during Cavour's ministry from French yards and designed as armoured floating batteries for coastal actions these vessels, the first Italian ironclads, were modified before completion into ironclad corvettes, able to fight also in open water, and their projected armament was reduced from 30 to 20 guns. They were rigged as three-masted schooners.
