French ironclad Couronne
 The French ironclad Couronne (Crown) was the first iron-hulled ironclad warship built for the French Navy in 1859–62. She was the first such ship to be laid down although the British armoured frigate HMS Warrior was completed first. The ship participated in the Franco-Prussian War of 1870–71 but saw no combat. She was served as a gunnery training ship from 1885 to 1908 before she was hulked the following year and became a barracks ship in Toulon.
