An ironclad is a steam-propelled warship protected by iron or steel armor plates, constructed from 1859 to the early 1890s. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells. The first ironclad battleship, Gloire, was launched by the French Navy in November 1859 - narrowly pre-empting the British Royal Navy.
The eighth HMS Vanguard of the British Royal Navy was an Audacious-class central battery ironclad battleship, by Edward Reed launched in 1870. In 1875, the ship was sunk during a summer cruise in a collision in fog with the ironclad HMS Iron Duke. None of the crew were lost, but the commanding officer of the ship never commanded another vessel in his career. The wreck lies near the Kish lightship off the coast of Ireland and is protected under the Irish National Monument Act.
Magenta was the lead ship of her class of two broadside ironclads built for the French Navy in the early 1860s. She served as flagship of the Mediterranean Squadron.
Jeanne d'Arc was a wooden-hulled armored corvette built for the French Navy in the late 1860s. She was named for Joan of Arc, a Roman Catholic saint and heroine of the Hundred Years War. Jeanne d'Arc participated in the Franco-Prussian War of 1870–1871 and remained in commission afterwards, unlike many of her sisters. The ship was condemned in 1883, but nothing further is known as to her disposition.
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.
Magenta was an ironclad barbette ship of the French Navy built in the 1880s and early 1890s. She was the third and final member of the Marceau class. The Marceau class was based on the earlier Amiral Baudin class of barbette ships, but with smaller guns: four 340 mm (13.4 in) weapons compared to the three 420 mm (16.5 in) guns of the earlier vessels. The ships introduced the lozenge arrangement for their main battery that became common for many French capital ships built in the 1890s. Magenta and her sister ships suffered from a number of problems, including poor stability, insufficient armor protection, and excessive displacement.
The French ironclad Alma was a wooden-hulled armored corvette built for the French Navy in the late 1860s. The lead ship of her class, she was named after the 1854 Battle of Alma of the Crimean War. The ship spent her early career on the China Station and later supported the French occupation of Tunisia in 1881. She was condemned in 1886, but was not sold until 1893.
The French ironclad Armide was a wooden-hulled armored corvette built for the French Navy in the mid-1860s. Placed into reserve after completion, she was first mobilized for the Franco-Prussian War of 1870–1871. She spent the rest of her career in the Mediterranean and then in the Far East as flagship of the French squadrons there, until her decommissioning in 1880. Armide was use as a target for gunnery trials in 1886.
The French ironclad Atalante was a wooden-hulled armored corvette built for the French Navy in the mid-1860s. She played a minor role in the Franco-Prussian War of 1870, bombarded Vietnamese forts during the Battle of Thuận An in 1884 and participated in the Sino-French War of 1884–1885. Atalante was reduced to reserve in Saigon, French Indochina, in 1885 and sank there two years later after having been condemned.
The French ironclad Reine Blanche was a wooden-hulled armored corvette built for the French Navy in the late 1860s as an improvement over the armored corvette Belliqueuse. She played a minor role in the Franco-Prussian War of 1870–1871 and was accidentally rammed by one of her sister ships in 1877. The ship bombarded the port of Sfax during the French occupation of Tunisia in 1881 before being sent to the Pacific in 1884. She quickly returned to port with worn-out boilers and was condemned later that year.
The French ironclad Thétis was a wooden-hulled armored corvette built for the French Navy in the late 1860s. She was named for the Greek sea-goddess Thetis. During the Franco-Prussian War of 1870–1871 she was assigned to a squadron of French ships that attempted to blockade the Prussian ports in the Baltic Sea in 1870. She accidentally rammed her sister Reine Blanche in 1877. En route to the Pacific in 1884 her propeller fell off and she had to return to France under sail. Thétis was eventually hulked in New Caledonia.
The Alma-class ironclads were a group of seven wooden-hulled, armored corvettes built for the French Navy in the mid to late 1860s. Three of the ships attempted to blockade Prussian ports in the Baltic Sea in 1870 during the Franco-Prussian War. Three others patrolled the North Sea and the Atlantic, while the last ship was en route to Japan when the war began and blockaded two small Prussian ships in a Japanese harbor. Afterwards they alternated periods of reserve and active commissions, many of them abroad. Three of the ships participated in the French occupation of Tunisia in 1881 while another helped to intimidate the Vietnamese Government into accepting status as a French protectorate and played a small role in the Sino-French War of 1884–85.
The La Galissonnière-class ironclads were a group of wooden-hulled, armored corvettes built for the French Navy during the 1870s, meant as a heavier armed and faster version of the Alma-class ironclads. While all three ships were begun before the Franco-Prussian War of 1870–71, the construction of the last two ships was delayed for years. The navy took advantage of the extended construction time of the latter ships to upgrade their armament. La Galissonnière bombarded Sfax in 1881 as part of the French occupation of Tunisia. She and her half-sister Triomphante participated in a number of battles during the Sino-French War of 1884–85. Their sister Victorieuse had a much quieter career. All three ships were decommissioned in the 1890s.
The Spanish ironclad Numancia was an armored frigate bought from France during the 1860s for service with the Royal Spanish Navy. The name was derived from the Siege of Numantia, in which Roman expansion in the Iberian Peninsula was resisted. She was the first ironclad to circumnavigate the Earth. She saw service in the Chincha Islands War and Cantonal Revolution.
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.
SMS Friedrich Carl was an ironclad warship built for the Prussian Navy in the mid-1860s. The ship was constructed in the French Societé Nouvelles des Forges et Chantiers shipyard in Toulon; her hull was laid in 1866 and launched in January 1867. The ship was commissioned into the Prussian Navy in October 1867. The ship was the third ironclad ordered by the Prussian Navy, after Arminius and Prinz Adalbert, though the fourth ship to be acquired, Kronprinz, was ordered after but commissioned before Friedrich Carl.
The French ironclad Flandre was one of ten Provence-class armored frigates built for the French Navy in the 1860s. Commissioned in 1865, she was initially assigned to the Northern Squadron and sometimes served as a flagship. The ironclad played a minor role in the Franco-Prussian War of 1870–1871, blockading the North Sea coast of Prussia. Flandre was decommissioned after the war and remained in reserve for the next decade and a half. The ship was disarmed in 1884 and was scrapped three years later.
The French ironclad Magnanime was one of 10 Provence-class armored frigates built for the French Navy during the 1860s. Commissioned in 1865, she was initially assigned to the Northern Squadron, but was soon transferred to the Mediterranean Squadron, often serving as a flagship. The ironclad played a minor role in the Franco-Prussian War of 1870–1871, blockading the North Sea coast of Prussia. Magananime was reduced to reserve after the war, but was reactivated in 1875 and assigned to the Mediterranean Fleet. The ship was decommissioned in 1878 and was stricken from the navy list in 1882. She was scrapped in 1885.
SMS Custoza was an ironclad warship built for the Austro-Hungarian Navy in the 1870s, the only member of her class. She was the first Austro-Hungarian ironclad to be built after the navy studied the results of the Battle of Lissa of 1866; she was also the first iron-hulled capital ship to be built for the Austro-Hungarian Navy. She was laid down in November 1869, launched in August 1872, and completed in February 1875. Her career was fairly limited, in part due to reduced naval budgets in the 1870s that also delayed her completion. Custoza was somewhat more active in the 1880s, taking part in an international naval demonstration against the Ottoman Empire in 1880, being modernized in 1882, and a trip to Spain for the Barcelona Universal Exposition in 1888. The ship became a training ship in 1902, was converted into a barracks ship in 1914, and after World War I, was awarded as a war prize to Italy. Custoza was immediately broken up.
