These two vessels were the first battleships in the world rigged only with a military mast and armed with giant guns, and were the first Italian 2-shaft capital ships. They were designed by Director Eng Benedetto Brin. The original plan was for four 35t guns, then for 60t guns, but 100t weapons were actually fitted. Armstrong-built MLs, these fired one 865kg projectile every 15 minutes, with a muzzle velocity of 454-509m/s. Aboard Duilio, at the stern, was a compartment for a small TB (Clio, 261t).
The belt was of Creusot steel plates; the armoured central citadel, redoubt and turrets were NS, the turrets being mounted en echelon close together amidships. There was a cellular raft at the bows and stern between an underwater deck and that next above, subdivided into 83 watertight compartments.

Duilio was disarmed on 27.6.1909, hulked and, renumbered GM40, used as a floating coal and oil tank. Dandolo was rebuilt in 1895/8 to Insp Eng Giacinto Pullino's design. During World War I she served as a local defence ship, first at Brindisi and later at Valona. She was removed from the Navy list on 23.1.1920.
