HMS Scorpion was an ironclad turret ship built by John Laird Sons & Company, at Birkenhead, England. She was one of two sister ships secretly ordered from the Laird shipyard in 1862 by the Confederate States of America.
HMS Dreadnought was an ironclad turret ship built for the Royal Navy during the 1870s. Construction was halted less than a year after it began and she was redesigned to improve her stability and buoyancy. Upon completion in 1879, the ship was placed in reserve until she was commissioned in 1884 for service with the Mediterranean Fleet. Upon her return 10 years later, she became a coast guard ship in Ireland for two years. The ship then became a depot ship in 1897 before she was reclassified as a second-class battleship in 1900. Dreadnought participated in the annual fleet manoeuvres for the next two years before she became a training ship in 1902. The ship was taken out of service three years later and sold for scrap in 1908.
HNLMS Schorpioen is a Schorpioen-class monitor built in France for the Royal Netherlands Navy in the 1860s. These new ships were equipped with heavy rifled 23 cm (9 in) guns, and a heavy armor. The hull had an armor plated belt of 15 cm (6 in) and the gun turret, housing the two guns, had almost 30 cm (12 in) of armor.
Aki (安芸) was one of two Satsuma-class semi-dreadnought battleship built for the Imperial Japanese Navy (IJN) during the first decade of the 20th century. She was the second battleship built domestically in Japan and the first to use steam turbines for propulsion. The ship was named for Aki Province, now a part of Hiroshima Prefecture. The ship saw no combat during World War I. Aki was disarmed in 1922 and sunk as a target in 1924 in accordance with the terms of the Washington Naval Treaty of 1922.
The Satsuma class was a pair of semi-dreadnought battleships built for the Imperial Japanese Navy (IJN) in the first decade of the 20th century. They were the first battleships to be built in Japan and marked a transitional stage between the pre-dreadnought and true dreadnought designs. They saw no combat during World War I, although Satsuma led a squadron that occupied several German colonies in the Pacific Ocean in 1914. Both ships were disarmed and expended as targets in 1922–1924 in accordance with the terms of the Washington Naval Treaty of 1922.
ARA Pueyrredón was one of four Giuseppe Garibaldi-class armored cruisers purchased by the Argentine Navy from Italy in the 1890s.

She participated in the 1864–70 War of the Triple Alliance between Brazil, Argentina and Uruguay against Paraguay, and took part in the Passage of Humaitá.
The Brazilian ironclad Lima Barros was originally ordered by Paraguay in 1864 with the name Belona, but was sold to Brazil when Paraguay could not make the final payments. She participated in the 1864–70 War of the Triple Alliance between Brazil, Argentina and Uruguay against Paraguay.
The Brazilian ironclad Silvado was originally ordered by Paraguay in 1864 with the name Nemesis, but was sold to Brazil when Paraguay could not make the final payments. She participated in the 1864–70 War of the Triple Alliance between Brazil, Argentina and Uruguay against Paraguay.
The Danish ironclad Peder Skram was originally laid down as a wooden steam frigate for the Royal Danish Navy, but was converted to an armored frigate while under construction in the early 1860s. She had an uneventful career before she was stricken from the Navy List on 7 December 1885. The ship was converted into an accommodation ship that year and was broken up in 1897.
The Spanish ironclad Arapiles was a wooden-hulled armored frigate bought from England during the 1860s for the Spanish Navy. Begun as an unarmored steam frigate, she was converted into an ironclad while under construction. Damaged when she ran aground in early 1873, she was under repair in the United States during the Virginius Affair later that year as tensions rose between the US and Spain over the incident. The ship was hulked in 1879 and the poor condition of her hull forced her reconstruction to be cancelled in 1882. Arapiles was scrapped a year or two later.
The Admiral Lazarev class was a pair of monitors built for the Imperial Russian Navy in the late 1860s, which designated them as armored turret frigates. Four ships were ordered, but the last two were significantly modified during construction and became the separate Admiral Spiridov class. The sister ships were assigned to the Baltic Fleet upon completion and remained there for their entire careers. Aside from one accidental collision, their careers were uneventful. They were reclassified as coast-defense ironclads in 1892 before they became training ships later that decade. The Admiral Lazarevs were stricken from the Navy List in 1907 and 1909; both were sold for scrap in 1912.
The Admiral Spiridov class were a pair of monitors built for the Imperial Russian Navy in the late 1860s. The sister ships were assigned to the Baltic Fleet upon completion and remained there for their entire careers. Aside from several accidental collisions and one grounding, their careers were uneventful. They were reclassified as coast-defense ironclads in 1892 before they became training ships in 1900. The Admiral Spiridovs were stricken from the Navy List in 1907; one ship became a stationary target and the other a coal-storage barge. Their ultimate fates are unknown.
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 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.
HNLMS Guinea was an Buffel-class monitor built for the Royal Netherlands Navy in the early 1870s. Rearmed in 1887 with more modern ordnance, she was sold for scrap in 1897.
The Schorpioen-class monitors were a pair of ironclad monitors built abroad for the Royal Netherlands Navy in the 1860s. They had uneventful careers and were stricken from the Navy List in the first decade of the 20th century. Stier became a target ship and was sunk in 1925. Schorpioen was converted into an accommodation ship in 1909. She was captured by the Germans during World War 2, but survived the war. She remained in service until 1982 and then became a museum ship.
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.
