Ironclad warship. An ironclad is a steam-propelled warship protected by iron or steel armor plates used in the early part of the second half of the 19th century.[1] The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells.
Why are the ironclads important? There are three main reasons. First, the ironclads were some of the first ships in history to be armored with metal and propelled by steam instead of by the wind. This development led directly to modern warships, so the ironclads were in some sense the great-grandparents of today's ships.
