"Regina Elena" was active in both the Italo-Turkish War with the Ottoman Empire in 1911–1912, where she participated in the Italian conquest of Cyrenaica, and World War I in 1915–1918, where she saw no action due to the threat of submarines in the narrow confines of the Adriatic Sea.She was retained for a few years after the war, but was ultimately stricken in February 1923 and broken up for scrap.
