CSS Muscogee was a Confederate casemate ironclad constructed in Columbus, Georgia, during the American Civil War. Originally built as a sister ship to CSS Missouri, she was designed by Chief Naval Constructor John L. Porter as a sternwheel-powered vessel. Her initial construction faced significant challenges; her first launch attempt on January 1, 1864, failed due to her excessive weight, prompting a substantial rebuild. During reconstruction, she was lengthened to approximately 223.5 feet overall, with a beam of 59 feet and a shallow draft of 8 feet, to accommodate new propulsion arrangements. The sternwheel was removed, and she was fitted with a pair of single-cylinder, horizontal steam engines from Columbus Naval Iron Works, each driving a 7.5-foot propeller, replacing the original engines from the steamboat Time. The overhaul also included a reduction in casemate length, which helped decrease her weight. The vessel’s casemate was armored with 4 inches of wrought iron and featured ten gun ports, with armament comprising four 7-inch and two 6.4-inch Brooke rifles, mounted on pivoting mounts. Her armament was capable of firing shells weighing up to 110 pounds. The casemate's armor extended to cover the deck and sides of the fantail with 2-inch thick plates, providing critical protection for her gun crews. Construction began in 1862 at the Columbus Naval Yard, but her completion was delayed by shortages of iron plate. She was renamed CSS Jackson sometime during 1864 and was finally launched in December 1864. However, her service was cut short when Union troops captured Columbus, Georgia, on April 17, 1865. Union forces set her ablaze during her fitting-out process, causing significant fire damage. She drifted downstream and ran aground, remaining inoperable. Her remains were salvaged in the early 1960s, with her stern and bow sections recovered and displayed at the National Civil War Naval Museum. The site includes a detailed outline of her original dimensions and armor, serving as a significant artifact of Civil War naval engineering. Recognized for her historical importance, CSS Jackson was listed on the National Register of Historic Places in 1970.
