Duilio was the lead ship of the Duilio class of ironclad turret ships built for the Italian Regia Marina (Royal Navy). Named for the Roman admiral Gaius Duilius, the ship was laid down in January 1873, was launched in May 1876, and was completed in January 1880. She was armed with a main battery of four 450 mm (17.7 in) guns, then the largest gun afloat, and she was capable of a top speed of around 15 knots (28 km/h; 17 mph).
Duilio's career was uneventful. She spent her first two decades in service with the Active and Reserve Squadrons, primarily tasked with training maneuvers and exercises. She was withdrawn from front-line duty in 1902 and thereafter employed as a training ship, though this role only lasted until 1909 when she was converted into a floating oil tank and renamed GM40. The ship's ultimate fate is unknown.
