CSS Palmetto State, an ironclad ram, was built by Cameron and Co., Charleston, South Carolina in January 1862, under the supervision of Flag Officer D. N. Ingraham, CSN. She was readied for service by September 1862 when Lieutenant Commander John Rutledge, CSN, was placed in command. Her armor was 4" thick on the shield, backed by 22" of wood, 2" of iron elsewhere. Her pilothouse was located abaft the stack. Palmetto State was burned by the Confederates upon the evacuation of Charleston on February 18, 1865.
