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.
H. L. Hunley (submarine) H. L. Hunley, often referred to as Hunley, was a submarine of the Confederate States of America that played a small part in the American Civil War. "Hunley" demonstrated the advantages and the dangers of undersea warfare. She was the first combat submarine to sink a warship, although "Hunley" was not completely submerged and, following her successful attack, was lost along with her crew before she could return to base. The Confederacy lost 21 crewmen in three sinkings of "Hunley" during her short career. She was named for her inventor, Horace Lawson Hunley, shortly after she was taken into government service under the control of the Confederate States Army at Charleston, South Carolina.
