With the advent of the screw propeller came the idea of cladding warships in iron as a means of protection from enemy gun fire. Metallurgy at the time developed to the point that iron was mass-produced, inexpensive, and readily available. The first actual iron-cladded vessels were floating barges which served as gun platforms, and towed into place in the Black Sea during the Crimean War. The first warship actually armored was the French ''La Gloire'' (1859), a three-masted vessel with a heavy timber frame overlaid with iron plating four inches thick. Not to be outdone, Great Britain launched the steam frigate HMS ''Warrior'' (1860), the first warship built entirely of iron. | With the advent of the screw propeller came the idea of cladding warships in iron as a means of protection from enemy gun fire.
