Completed in 1917, the ship played a small role in the 11th Battle of the Isonzo later that year. She was decommissioned in 1924, but returned to service as the floating battery "GM 194" at the beginning of World War II and was towed to Genoa and where she spent the rest of the war. The ship had her guns disabled when the Royal Navy bombarded Genoa in 1941. "GM 194" was captured by the Germans after the Italian Armistice in 1943 and was turned over to the puppet (Italian Social Republic) that they installed afterward. She was scuttled at the end of the war and subsequently scrapped.
