Dunderberg, which is a Swedish word meaning "thunder(ing) mountain", was an ocean-going casemate ironclad of 14 guns built for the Union Navy. She resembled an enlarged, two-masted version of the Confederate casemate ironclad CSS Virginia. She was originally designed to have both gun turrets and a casemate but the turrets were deleted while the ship was still being built. Construction began in 1862, but progress was slow and she was not launched until after the end of the American Civil War in 1865.
The French ironclad Colbert was the lead ship of the Colbert-class ironclads that were built for the French Navy in the 1870s. The ship was the flagship of the Mediterranean Squadron for most of her career. She took part in the French conquest of Tunisia, notably shelling and landing troops in Sfax on 15–16 July 1881. Colbert was paid off in 1895 and condemned in 1900. The ship was finally sold for scrap in 1909.
The Colbert class were a pair of armored frigates built for the French Navy during the 1870s. The ships served as the flagships of the commander and deputy commander of the Mediterranean Squadron for most of their careers. The sister ships took part in the French conquest of Tunisia, notably shelling and landing troops in Sfax in 1881. They were relegated to second-line roles in 1894–95 before being condemned in 1900. The ships were finally sold for scrap in 1909.
Océan was a wooden-hulled, armored frigate built for the French Navy in the mid to late 1860s and the lead ship of her class. She was commissioned in 1870 to participate in the Franco-Prussian War and was assigned to the Baltic Squadron that unsuccessfully attempted to blockade Prussian ports in the Baltic Sea. The ship later served in both the Northern and Mediterranean Squadrons before being discarded in 1894.
The French ironclad Trident was the second and last ship of the Colbert-class ironclads that were built for the French Navy in the 1870s. The ship was the flagship of the deputy commander of the Mediterranean Squadron for most of her career. She took part in the French occupation of Tunisia, notably shelling and landing troops in Sfax in 1881. Trident was reclassified as a training ship in 1894 and condemned in 1900, before she was finally sold for scrap in 1909.
The Gueydon-class cruiser was a three-ship class of armored cruisers built in the first decade of the twentieth century for the French Navy.
HNoMS Mjølner was the fourth of five ships of the John Ericsson-class monitors built for the Royal Swedish Navy and the Royal Norwegian Navy in the mid-1860s. Impressed by the use of ironclads during the American Civil War, the design was based on that of USS Monitor. They were designed under the supervision of the Swedish-born inventor, John Ericsson—coincidentally, designer of Monitor—, and built in Sweden. Mjølner was delivered in 1868 and ran aground the following year, although she was not seriously damaged. The ship was reconstructed in 1897 and given modern breech-loading guns. Mjølner was sold for scrap in 1909.
Marengo was a wooden-hulled, armored frigate of the Océan class, built for the French Navy in the mid to late 1860s. The ship was running her sea trials in July 1870 when the Franco-Prussian War began and was immediately placed in reserve until after the war was over. Marengo participated in the French occupation of Tunisia in 1881 and was flagship of the Northern Squadron in 1891 when it made port visits in Britain and Russia. She was sold for scrap in 1896.
Suffren was a wooden-hulled, armored frigate of the Océan class, built for the French Navy in the mid to late 1860s. Although she was laid down in 1866, the ship was not launched until 1870 and commissioned in 1876. Suffren was one of the French ships assigned to the international squadron gathered to force the Ottoman Empire to carry out its obligations under the Treaty of Berlin in 1880. The ship was paid off in 1895 and discarded two years later.
The Danish ironclad Lindormen was a monitor built for the Royal Danish Navy in the 1860s. She was scrapped in 1907.
The Danish ironclad Gorm was a monitor built for the Royal Danish Navy in the 1860s. She was scrapped in 1912.

HNLMS Prins Hendrik der Nederlanden was an ironclad ramtorenschip built in Great Britain for the Royal Netherlands Navy in the mid-1860s. She was transferred to the Dutch East Indies in 1876 and participated in the Dutch intervention in Lombok and Karangasem in 1894. The ship was hulked in 1899 and scrapped in 1925.
The Charodeika class was a pair of monitors built for the Imperial Russian Navy in the late 1860s. They were designed by the British shipbuilder Charles Mitchell and built in Saint Petersburg. Both ships were assigned to the Baltic Fleet and had fairly uneventful careers mostly assigned to training units. Rusalka struck a rock in 1869 and had to be run aground lest she sink. They were reclassified as coast-defense ironclads in 1892 and Rusalka sank during a storm in the Gulf of Finland the next year with the loss of all hands. Her sister ship Charodeika continued in service until 1907 and was eventually scrapped in 1911–12. Rusalka's wreck was discovered in 2003 by an expedition sponsored by the Estonian Maritime Museum.
The French cruiser Sully was one of five armored cruisers of the Gloire class that were built for the French Navy in the early 1900s. Fitted with a mixed armament of 194-millimeter (7.6 in) and 164.7-millimeter (6.5 in) guns, the ships were designed for service with the battle fleet. Completed in 1904, Sully joined her sister ships in the Northern Squadron, although she was transferred to the Far East shortly afterwards. The ship struck a rock in Hạ Long Bay, French Indochina in 1905, only eight months after she was completed, and was a total loss.
The Russian monitor Admiral Greig was the second and last of the two Admiral Lazarev-class monitors built for the Imperial Russian Navy in the late 1860s. She was assigned to the Baltic Fleet upon completion and remained there for her entire uneventful career. She was reclassified as a coast-defense ironclad in 1892 before she became a training ship later that decade. Admiral Greig was decommissioned in 1907, stricken from the Navy List in 1909 and scrapped in 1912.
The Russian monitor Charodeika was the lead ship of her class of monitors built for the Imperial Russian Navy in the 1860s. She served for her entire career with the Baltic Fleet, mostly as a training ship. She was decommissioned in 1907, but was not broken up until 1911–12.
The Buffel-class monitors were a pair of ironclad monitors built for the Royal Netherlands Navy in the 1860s. They had uneventful careers and were stricken from the Navy List in the late 1890s. Guinea was scrapped in 1897, but Buffel was hulked and converted into an accommodation ship in 1896. She was captured by the Germans during World War II, but survived the war. She became a museum ship in 1979.
