CSS Arkansas was the lead ship of her class of two casemate ironclads built for the Confederate States Navy during the American Civil War. Completed in 1862, she saw combat in the Western Theater when she steamed through a United States Navy fleet at Vicksburg in July. Arkansas was set on fire and destroyed by her crew after her engines broke down several weeks later. Her remains lie under a levee above Baton Rouge, Louisiana at 30°29′14″N 91°12′5″W.
