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.
HMS Neptune (1874) HMS "Neptune" was an ironclad turret ship originally designed and built in Britain for Brazil, but acquired for the Royal Navy in 1878. Modifications to suit the Royal Navy took three years to complete and the ship did not begin her first commission until 1883 with the Channel Fleet. She was transferred to the Mediterranean Fleet in 1885, but refitted in Portsmouth in 1886–87. "Neptune" then became the coastguard ship for the 1st Class Reserve at Holyhead until 1893 when she was placed in in Portsmouth. While she was being towed to the breakers in 1903, "Neptune" unintentionally rammed HMS "Victory" , then serving as a training hulk for the Naval Signal School, collided with HMS "Hero" , and narrowly missed several other ships. She was scrapped in Germany in 1904.
