Warrior

…Great Eastern (1856) and HMS Warrior (1860), the world’s first wholly ironclad battleship. He wrote several books, including On the Nature, Properties, and Applications of Steam, and on Steam Navigation (1841) and The Modern System of Naval Architecture, 3 vol. (1864–65).

…Great Britain countered with the Warrior, the first iron-hulled, seagoing, armoured man-of-war. Much larger than the Gloire, she displaced 9,210 tons, mounted 28 seven-inch (18-cm) shell guns, had slightly lighter armour, carried sails, and was one knot faster.
