With its limited shipbuilding capacity, the Confederate navy found it more advantageous to build a few impregnable warships to combat the numerically superior Union navy.

The Confederacy concluded in June 1861 that ironclad warships would best suit its needs. The Civil War clearly demonstrated the superiority of ironclads and revolutionized naval warfare. Attempts to armor war vessels had been made during the 300 years prior to the American Civil War, but it was not until the mid-nineteenth century that steam-powered warships and the development of large-caliber rifled cannons made armoring practical and indeed necessary. Other names for these ships include rams, armorclads, iron gophers, iron elephants, iron coffins, turtle-backs, and mud-crushers. Ironclads were warships designed to be impervious to enemy shot and shell by virtue of their iron-armored wooden hulls.
