A ship of the line was a type of naval warship constructed during the Age of Sail from the 17th century to the mid-19th century. The ship of the line was designed for the naval tactic known as the line of battle, which involved the two columns of opposing warships maneuvering to volley fire with the cannons along their broadsides. In conflicts where opposing ships were both able to fire from their broadsides, the opponent with more cannons firing – and therefore more firepower – typically had an advantage.
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. Although Britain built the first completely iron-hulled warships.
The first HMS Shah was a 19th-century unarmoured iron hulled, wooden sheathed frigate of Britain's Royal Navy designed by Sir Edward Reed. She was originally to be named HMS Blonde but was renamed following the visit of the Shah of Persia in 1873.
Hydra was an ironclad warship of the Greek Navy, named for Hydra, one of the Saronic Gulf islands which played a key role in the war at sea during the Greek War of Independence. The lead ship of her class of ironclads, she was ordered in 1885 in response to a crisis in the Balkans and Ottoman naval expansion. The ship was launched in 1889 and delivered to Greece by 1892. She was armed with a main battery of three 10.8 in (270 mm) guns and five 5.9 in (150 mm) guns, and had a top speed of 17 kn.
Psara was a steel-built ironclad warship named for one of the Aegean Sea islands that played a key role in the war at sea during the Greek War of Independence. The final vessel of the Hydra class, she was ordered in 1885 in response to a crisis in the Balkans and Ottoman naval expansion. The ship was launched in 1889 and delivered to Greece by 1902. She was armed with a main battery of three 10.8 in (270 mm) guns and five 5.9 in (150 mm) guns, and had a top speed of 17 kn.
The Dévastation was an Dévastation-class ironclad battleship of the French Navy of central battery (casemate) design. She was used as a school ship for manoeuvres.
Affondatore was an armoured ram of the Regia Marina, built in the 1860s by Harrison, Millwall, London. Construction commenced in 1863; the ship, despite being incomplete, was brought to Italy during the Third Italian War of Independence. Affondatore, which translates as "Sinker", was initially designed to rely on her ram as her only weapon, but during construction she was also equipped with two 300-pounder guns.
Formidable was an ironclad barbette ship built for the French Navy between her keel laying in late 1879 and her completion in early 1889. She was the second and final member of the Amiral Baudin class. The ships of the class was designed in response to Italian naval expansion, and carried a main battery of three 370 mm (14.6 in) guns all mounted in open barbettes on the centerline. The armament was chosen after public pressure to compete with the very large guns mounted on the latest Italian ironclads.
Amiral Duperré was an ironclad barbette ship built for the French Navy in the 1870s and 1880s; she was the first vessel of that type built by France. She carried her main battery of four 34 cm (13.4 in) guns individually in open barbette mountings, which offered increased fields of fire compared to earlier central battery ships, though they were less well protected. Amiral Duperré was ordered as part of a French naval construction program aimed at countering the growth of the Italian fleet, which had begun work on the very large ironclads of the Duilio and Italia classes in the early 1870s. The Italian vessels, armed with 45 cm (17.7 in) guns, prompted public outcry in France that pressured the navy to develop larger guns for its own ships. Amiral Duperré's design served as the basis for several follow-on classes, including the Bayard and Amiral Baudin classes.
Bayard was the lead ship of the Bayard class of ironclad barbette ships built for the French Navy in the late 1870s and 1880s. Intended for service in the French colonial empire, she was designed as a "station ironclad", smaller versions of the first-rate vessels built for the main fleet. The Vauban class was a scaled down variant of Amiral Duperré. They carried their main battery of four 240 mm (9.4 in) guns in open barbettes, two forward side-by-side and the other two aft on the centerline. Bayard was laid down in 1876 and was commissioned in 1882.
Lepanto was an Italian ironclad battleship built for the Italian Regia Marina, the second and last ship of the Italia class. Lepanto was laid down in November 1876, launched in March 1883, and completed in August 1887. She was armed with a main battery of four 432 mm (17 in) guns mounted in a central barbette and was capable of a top speed of 17.8 knots. Unlike other capital ships of the era, Lepanto had an armored deck rather than the more typical belt armor.
Ruggiero di Lauria was an ironclad battleship built in the 1880s for the Italian Regia Marina. She was the lead ship of the Ruggiero di Lauria class, which included two other ships, Francesco Morosini and Andrea Doria. Ruggiero di Lauria, named for the medieval Sicilian admiral Ruggiero di Lauria, was armed with a main battery of four 432 mm (17 in) guns, was protected with 451 mm (17.75 in) thick belt armor, and was capable of a top speed of 17 knots.
Francesco Morosini was an ironclad battleship built in the 1880s and 1890s for the Italian Regia Marina. The ship, named for Francesco Morosini, the 17th-century Doge of Venice, was the second of three ships in the Ruggiero di Lauria class, along with Ruggiero di Lauria and Andrea Doria. She was armed with a main battery of four 356 mm (14 in) guns, was protected with 451 mm (17.75 in) thick belt armor, and was capable of a top speed of 17 knots.
The Océan-class ironclads were a class of three wooden-hulled armored frigates built for the French Navy in the mid to late 1860s. Océan attempted to blockade Prussian ports in the Baltic Sea in 1870 during the Franco-Prussian War and Marengo participated in the French conquest of Tunisia in 1881. Suffren was often used as the flagship for the Cherbourg Division, the Channel Division, Mediterranean Squadron and the Northern Squadron during her career. The ships were discarded during the 1890s.
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.
SMS Lissa, named for the Battle of Lissa, was a unique ironclad warship built for the Austro-Hungarian Navy in the 1860s and 1870s, the only member of her class. She was the first casemate ship built for Austria-Hungary, she was armed with a main battery of twelve 9-inch (229 mm) guns in a central armored casemate, unlike the earlier broadside ironclads. Construction of the ship lasted from June 1867 to May 1871, and was delayed by budgetary shortfalls; the lack of funding also plagued the ship during her career, preventing her from taking an active role in the fleet. She spent the majority of her time in service laid up in Pola, apart from a lengthy reconstruction in 1880–1881. Lissa was ultimately stricken from the fleet in 1892 and broken up for scrap starting the following year.
Asar-i Şevket was a central battery ship built for the Ottoman Navy in the 1860s. Originally ordered by the Eyalet of Egypt but confiscated by the Ottoman Empire while under construction, the vessel was initially named Kahira. The ship was laid down at the French Forges et Chantiers de la Gironde shipyard in 1867, was launched in 1868, and was commissioned into the Ottoman fleet in March 1870. Asar-i Şevket was armed with a battery of four 178 mm (7 in) Armstrong guns in a central casemate and one 229 mm (9 in) Armstrong gun in a revolving barbette.
Requin was an ironclad barbette ship built for the French Navy in the late 1870s and early 1880s. She was last member of the four-ship Terrible class. They were built as part of a fleet plan started in 1872, which by the late 1870s had been directed against a strengthening Italian fleet. The ships were intended for coastal operations, and as such had a shallow draft and a low freeboard, which greatly hampered their seakeeping and thus reduced their ability to be usefully employed outside of coastal operations after entering service. Armament consisted of a pair of 420 mm (16.5 in) guns in individual barbettes, the largest-caliber gun ever mounted on a French capital ship. Requin was laid down in 1878 and was completed in 1887.
The Vauban class, sometimes referred to as the Duguesclin class, was a pair of two ironclad barbette ships built for the French Navy in the late 1870s and 1880s. The class consisted of Vauban, the lead ship, and Duguesclin. They were based on the ironclad Amiral Duperré, adopting the same general arrangement, but were scaled down in size. They were intended for use overseas in the French colonial empire, and as such, they retained a sailing rig for long-range cruising and copper sheathing for their hulls to protect them when they would be unable to be dry-docked regularly. They carried a main battery of four 240 mm (9.4 in) guns that were mounted in individual barbettes; two were in sponsons forward, abreast of the conning tower, and the other two were on the centerline aft.
Duguesclin was an ironclad barbette ship built for the French Navy in the late 1870s and 1880s; she was the second and final member of the Vauban class. Intended for service in the French colonial empire, she was designed as a "station ironclad", which were smaller versions of the first-rate vessels built for the main fleet. The Vauban class was a scaled down variant of Amiral Duperré. They carried their main battery of four 240 mm (9.4 in) guns in open barbettes, two forward side-by-side and the other two aft on the centerline. Duguesclin was laid down in 1879 and was completed in 1885. Despite the intention to use her overseas, the ship remained in home waters for the duration of her career, serving with the Mediterranean Squadron from 1888 to 1895, though the last two years were as part of the Reserve Division. She spent the next several years in the 2nd category of reserve, ultimately being struck from the naval register in 1904. She was sold for scrap the following year and broken up in Italy.
