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.
Roma-class ironclad The "Roma" class was a pair of ironclad warships built for the Italian "Regia Marina" (Royal Navy) in the 1860s and 1870s. The class comprised two ships, "Roma" and "Venezia" . "Roma" was a broadside ironclad armed with five 10 in and twelve 8 in guns, while "Venezia" was converted into a central battery ship during construction, armed with a much more powerful battery of eighteen 10-inch guns. Neither ship had an eventful career, due in large part to their rapid shift to obsolescence. "Venezia" and "Roma" were withdrawn from service for auxiliary duties in 1880 and 1890, respectively. Both were stricken from the naval register in 1895 and broken up for scrap the following year, "Roma" having been badly damaged in a fire in 1895.
