Who established the advisory board that developed the first ironclad warship?
USS Monitor USS "Monitor" was an iron-hulled steamship. Built during the American Civil War, she was the first ironclad warship commissioned by the Union Navy. "Monitor" is most famous for her central role in the Battle of Hampton Roads on 9 March 1862, where, under the command of Lieutenant John Worden, she fought the casemate ironclad  (built on the hull of the former steam frigate USS "Merrimack" ) to a standstill. The unique design of the ship, distinguished by its revolving turret which was designed by American inventor Theodore Timby, was quickly duplicated and established the monitor type of warship.
Italian ironclad Terribile Terribile was the first ironclad warship to be built for the Italian "Regia Marina" (Royal Navy), and the second member of the "Formidabile" class . "Terribile" and her sister, "Formidabile" , were both built in France. A broadside ironclad, she was laid down in June 1860, launched in February 1861, and was completed in September that year. She was the first Italian ironclad to enter service and was equipped with four 203 mm and sixteen 164 mm guns.
