CSS Virginia II was a Confederate Navy steam-powered ironclad ram laid down in 1862 at the William Graves' shipyard in Richmond, Virginia. Acting Constructor William A. Graves, CSN, was the superintendent in charge of her construction. In order to conserve scarce iron plating, he ordered the ship's armored casemate shortened from the specifications given in John L. Porter's original building plans; in addition, the ship's iron-plating, while six inches thick on the casemate's forward face, was reduced to five inches on her port, starboard, and aft faces. Due to the shortening of her casemate, the number of her cannon were reduced to a single 11" smoothbore, a single 8" rifle, and two 6.4" rifles.
