The list of units
The forerunner of the modern battleship, the Ironclad is a tough defender against anything but more modern warships.
A coastal city needs coal and iron in its Strategic Resource box to build an Ironclad.
In Civilization III: Conquests, the Ironclad underwent a major upgrade previously being made available with Steam Power now they need to be researched with their own special technology Ironclads. They also now upgrade to Destroyers. In addition their attack, defense, speed, production costs and bombard values all were modified:

Ironclads were the forerunners of future generations of armored naval vessels. Instead of the simple wooden hulls found on the other ships at the time, ironclads were covered with strong metal plating. This plating made them nearly impervious to large-caliber explosive shells that would easily penetrate and destroy wooden vessels. Ironclads made their first appearance during the American Civil War, and quickly gained dominance over other ships of that era. Perhaps the most famous naval battle of the Civil War was the battle between the Confederate ironclad "Merrimack", and the Union ironclad "Monitor", which lasted for several hours before the "Merrimack" was forced to withdraw.
- The model of the Ironclad unit is based on the USS Monitor ironclad.
