USS Keokuk was an experimental ironclad screw steamer of the United States Navy named for the city of Keokuk, Iowa. She was laid down in New York City by designer Charles W. Whitney at J.S. Underhill Shipbuilders, at the head of 11th Street. She was originally named Moodna, but was renamed while under construction, launched in December 1862 sponsored by Mrs. C. W. Whitney, wife of the builder, and commissioned in early March 1863 with Commander Alexander C. Rhind in command.
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.
Atlanta was a casemate ironclad that served in the Confederate and Union Navies during the American Civil War. She was converted from a British-built blockade runner named Fingal by the Confederacy after she made one run to Savannah, Georgia. After several failed attempts to attack Union blockaders, the ship was captured by two Union monitors in 1863 when she ran aground. Atlanta was floated off, repaired, and rearmed, serving in the Union Navy for the rest of the war. She spent most of her time deployed on the James River supporting Union forces there. The ship was decommissioned in 1865 and placed in reserve. Several years after the end of the war, Atlanta was sold to Haiti, but was lost at sea in December 1869 on her delivery voyage.
Kōtetsu, later renamed Azuma, was the first ironclad warship of the Imperial Japanese Navy. She was designed as an armored ram for service in shallow waters, but also carried three guns. The ship was built in Bordeaux, France, for the Confederate States Navy under the cover name Sphinx, but was sold to Denmark after sales of warships by French builders to the Confederacy was forbidden in 1863. The Danes refused to accept the ship and sold her to the Confederates which commissioned her as CSS Stonewall in 1865. The ship did not reach Confederate waters before the end of the American Civil War in April and was turned over to the United States.
CSS Tennessee was a casemate ironclad ram built for the Confederate Navy during the American Civil War. She served as the flagship of Admiral Franklin Buchanan, commander of the Mobile Squadron, after her commissioning. She was captured in 1864 by the Union Navy during the Battle of Mobile Bay and then participated in the Union's subsequent Siege of Fort Morgan. Tennessee was decommissioned after the war and sold in 1867 for scrap.
CSS Baltic was an ironclad warship that served in the Confederate States Navy during the American Civil War. A towboat before the war, she was purchased by the state of Alabama in December 1861 for conversion into an ironclad. After being transferred to the Confederate Navy in May 1862 as an ironclad, she served on Mobile Bay off the Gulf of Mexico. Baltic's condition in Confederate service was such that naval historian William N. Still Jr. has described her as "a nondescript vessel in many ways". Over the next two years, parts of the ship's wooden structure were affected by wood rot. Her armor was removed to be put onto the ironclad CSS Nashville in 1864. By that August, Baltic had been decommissioned. Near the end of the war, she was taken up the Tombigbee River, where she was captured by Union forces on May 10, 1865. An inspection of Baltic the next month found that her upper hull and deck were rotten and that her boilers were unsafe. She was sold on December 31, and was likely broken up in 1866.
CSS Palmetto State was one of six Richmond class casemate ironclad rams built for the Confederate States Navy during the American Civil War. Completed in 1862, she defended Charleston, South Carolina and was burnt in 1865 to prevent her capture by advancing Union troops.
CSS Chicora was a Confederate ironclad ram that fought in the American Civil War. It was built under contract at Charleston, South Carolina in 1862. James M. Eason built it to John L. Porter's plans, using up most of a $300,000 State appropriation for construction of marine batteries; Eason received a bonus for "skill and promptitude." Its iron shield was 4 inches (102 mm) thick, backed by 22 inches (559 mm) of oak and pine, with 2-inch (51 mm) armor at its ends. Keeled in March, it was commissioned in November, Commander John Randolph Tucker, CSN assuming command.
CSS Richmond was the name ship of her class of six casemate ironclads built for the Confederate States Navy during the American Civil War. Completed during 1862 the ship was assigned to the James River Squadron where she mostly supported Confederate forces near Richmond, Virginia. She was burned in April 1865 to prevent her capture by Union forces.
USS Canonicus was a single-turret monitor built for the United States Navy during the American Civil War, the lead ship of her class. The ship spent most of her first year in service stationed up the James River, where she could support operations against Richmond and defend against a sortie by the Confederate ironclads of the James River Squadron. She engaged Confederate artillery batteries during the year and later participated in both attacks on Fort Fisher, defending the approaches to Wilmington, North Carolina, from December 1864 to January 1865.
USS New Ironsides was a wooden-hulled broadside ironclad built for the United States Navy during the American Civil War. The ship spent most of her career blockading the Confederate ports of Charleston, South Carolina, and Wilmington, North Carolina, in 1863–65. New Ironsides bombarded the fortifications defending Charleston in 1863 during the First and Second Battles of Charleston Harbor. At the end of 1864 and the beginning of 1865 she bombarded the defenses of Wilmington in the First and Second Battles of Fort Fisher.
CSS Raleigh was a steam-powered Civil War casemate ironclad. She was fitted with a spar torpedo instead of an iron ram and was built in 1863–1864 by the Confederate States Navy at Wilmington, North Carolina. While she was being built her commander was Lieutenant John Wilkinson (CSN). She was put into commission on April 30, 1864 under the command of Lieutenant J. Pembroke Jones, CSN.
USS Roanoke was a wooden-hulled Merrimack-class screw frigate built for the United States Navy in the mid-1850s. She served as flagship of the Home Squadron in the late 1850s and captured several Confederate ships after the start of the American Civil War in 1861. The ship was converted into an ironclad monitor during 1862–63; the first ship with more than two gun turrets in history. Her conversion was not very successful as she rolled excessively and the weight of her armor and turrets strained her hull. Her deep draft meant that she could not operate off shallow Confederate ports and she was relegated to harbor defense at Hampton Roads, Virginia for the duration of the war. Roanoke was placed in reserve after the war and sold for scrap in 1883.
USS Catawba was a single-turreted Canonicus-class monitor built for the Union Navy during the American Civil War. Completed shortly after the end of the war, Catawba was laid up until sold to her builders in 1868, and then resold to the Peruvian Navy. Renamed BAP Atahualpa, the ship participated in the defense of main port of Peru, Callao, during the War of the Pacific. When the city of Lima was taken by Chilean troops in 1881, she was scuttled to prevent her capture. Atahualpa was later refloated and used as a storage hulk until scrapped in the early 20th century.
USS Manhattan was a single-turreted Canonicus-class monitor built for the Union Navy during the American Civil War. After commissioning in 1864 the ship was assigned to the West Gulf Blockading Squadron and participated in the Battle of Mobile Bay. At the end of the battle, Manhattan took the surrender of the Confederate casemate ironclad ram Tennessee. She bombarded Fort Morgan during the Siege of Fort Morgan and later blockaded the mouth of the Red River until the end of the war.
USS Mahopac (1864) was a Canonicus-class monitor built for the Union Navy during the American Civil War. The vessel was assigned to the James River Flotilla of the North Atlantic Blockading Squadron upon completion in September 1864. The ship spent most of her time stationed up the James River where she could support operations against Richmond and defend against sorties by the Confederate ironclads of the James River Squadron. She engaged Confederate artillery batteries during the year and later participated in both the first and second battles of Fort Fisher, defending the approaches to Wilmington, North Carolina, in December 1864 – January 1865. Mahopac returned to the James River after the capture of Fort Fisher and remained there until Richmond, Virginia was occupied in early April.
CSS Neuse was a steam-powered ironclad ram of the Confederate States Navy that served in the latter part the American Civil War and was eventually scuttled in the Neuse River to avoid capture by rapidly advancing Union Army forces. In the early 1960s, she produced approximately 15,000 artifacts from her raised lower hull, the largest number ever found on a recovered Confederate vessel. The remains of her lower hull and a selection of her artifacts are on exhibit in Kinston, North Carolina at the CSS Museum, which belongs to the North Carolina Department of Natural and Cultural Resources. The ironclad is listed on the National Register of Historic Places.
CSS Missouri was a casemate ironclad built by the Confederate States Navy during the American Civil War. Her propulsion machinery was taken from an existing steamboat, her armor was railroad T-rails, and she was armed with three captured cannon. She was difficult to steer and leaked badly. Additional equipment had to be added to bring allow her to reach her intended speed. Completed during 1863 on the Red River, she was trapped in the Shreveport, Louisiana, area by low water and never saw combat. The vessel's crew had desertion issues and some of her crewmen were pulled from the army. After traveling downriver for the first time, the ship was surrendered in June 1865 to the United States Navy—the last Confederate ironclad to be handed over—and sold in November.
The Kalamazoo-class monitors were a class of ocean-going ironclad monitors begun during the American Civil War. Unfinished by the end of the war, their construction was suspended in November 1865 and the unseasoned wood of their hulls rotted while they were still on the building stocks. If the four ships had been finished they would have been the most seaworthy monitors in the US Navy. One was scrapped in 1874 while the other three were disposed of a decade later.
CSS Nashville was a large side-wheel Nashville-class steam casemate ironclad built by the Confederates late in the American Civil War.
