Duilio-class ironclad

Ironclad warship class of the Italian Royal Navy

The Duilio class was a pair of ironclad turret ships built for the Royal Italian Navy in the 1870s and 1880s. The two ships, Duilio and Enrico Dandolo, were fitted with the largest guns available, 450 mm (17.7 in) rifled muzzle-loading guns, and were the largest, fastest and most powerful ships of their day. To save weight on such large vessels, the ship's designer, Benedetto Brin adopted a radical solution for the time: he reserved armor only for the central portion of the ship where it protected the ships' engines and ammunition magazines, while the rest of the hull were extensively sub-divided with watertight compartments.
