It was the ancient Chinese who built the first armored ship. It had overlapping plates connected with rings like scales on a snake attached to a wooden frame.
Basically, an "ironclad" was a steam-propelled warship fitted with plates of iron armor. The idea of an armored warship was not new; the Vikings used to line the sides of their longships with their shields, several shipbuilders came up with the idea of a ship encased in lead, and, most famously, the Koreans built a "turtle" ship in the sixteenth century, armored with iron and propelled by oars. None of these really led to further warship designs, so they are only historical curiosities. The steam-propelled ironclads of the 1800s, on the other hand, led directly to the warships of today.

The USS Monitor was the first Union ironclad warship.
The first Union ironclad warship for the Union in the US Civil War was the USS Monitor. It was designed by Swedish engineer, John Ericsson. The ship was unique in that it was the first warship to have a revolving turret. This enabled the ship to always be able to aim its cannons on an enemy warship. The USS Monitor was built in 1862 and battled the CSS Virginia at the Battle of Hampton Roads.

Technically, the first steel hulled ship was the French warship 'Redoubtable ' in 1876. However, iron hulled ships had been used 30 years before this.
The first clash of a metal warship with a revolving gun turret fighting another metal warship in actual battle.
An American, David Busnell built the first successful military sub; piloted by Sgt. Lee of the Continental Army, the "Turtle" attacked a British warship (unsuccessfully) in 1776.
The warship Monitor was developed in 1862
