Dévastation-class ironclad floating battery

The Dévastation-class ironclad floating batteries were built for the attack of Russian coastal fortifications during the Crimean War. France had intended to build ten of these vessels, but in the time available was only able to construct five in French shipyards, of which the first three took part in the attack on Kinburn in 1855. The Congrève was scrapped in 1867 and the other four in 1871.
