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, though Britain built the first completely iron-hulled warships.
The seventh HMS Enterprise of the Royal Navy was an armoured sloop launched in 1864 at Deptford Dockyard. Originally laid down as a wooden screw sloop of the Camelion class, she was redesigned by Edward Reed and completed as a central battery ironclad. The ship spent the bulk of her career assigned to the Mediterranean Fleet before returning to England in 1871 where she was paid off. Enterprise was sold for scrap in 1885.
HMS Warrior is a 40-gun steam-powered armoured frigate built for the Royal Navy in 1859–1861. She was the name ship of the Warrior-class ironclads. Warrior and her sister ship HMS Black Prince were the first armour-plated, iron-hulled warships, and were built in response to France's launching in 1859 of the first ocean-going ironclad warship, the wooden-hulled Gloire. Warrior conducted a publicity tour of Great Britain in 1863 and spent her active career with the Channel Squadron. Obsolescent following the 1873 commissioning of the mastless and more capable HMS Devastation, she was placed in reserve in 1875, and was "paid off" – decommissioned – in 1883.
The Nelson class was a class of two battleships of the British Royal Navy, built shortly after, and under the terms of, the Washington Naval Treaty of 1922. They were the only British battleships built between the Revenge class and the King George V class, ordered in 1936.
HMS Malaya was one of five Queen Elizabeth-class battleships built for the Royal Navy during the 1910s. Shortly after commissioning in early 1916, she participated in the Battle of Jutland of the First World War as part of the Grand Fleet. In the Second World War, Malaya served mostly in escort duties in the Mediterranean Sea and Atlantic Ocean. She was withdrawn from service at the end of 1944, and sold for scrap in 1948.
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.
The Warrior-class ironclads were a class of two warships built for the Royal Navy between 1859 and 1862, the first ocean-going ironclads with iron hulls ever constructed. The ships were designed as armoured frigates in response to an invasion scare sparked by the launch of the French ironclad Gloire and her three sisters in 1858. They were initially armed with a mix of rifled breech-loading and muzzle-loading smoothbore guns, but the Armstrong breech-loading guns proved unreliable and were ultimately withdrawn from service.
HMS Royal Oak was a Prince Consort-class armoured frigate built for the Royal Navy in the 1860s. The lead ship of her class, she is sometimes described as a half-sister to the other three ships because of her different engine and boiler arrangements. Like her sisters, she was converted into an ironclad from a wooden ship of the line that was still under construction.
The Prince Consort class of ironclad battleship were four Royal Navy wooden-hulled broadside ironclads: HMS Royal Oak, HMS Prince Consort, HMS Ocean, and HMS Caledonia. They were originally laid down as Bulwark-class battleship, but were converted to ironclads. Royal Oak was Britain's fifth ironclad battleship completed.
HMS Research was a small ironclad warship, converted from a wooden-hulled sloop and intended as an experimental platform in which to try out new concepts in armament and in armour. She was launched in 1863, laid up in 1878 and sold for breaking in 1884, having displayed serious limitations as a warship.
HMS Royal Alfred was a central-battery ironclad frigate of the Victorian era, serving with the Royal Navy. She was half-sister to HMS Zealous and HMS Repulse.
HMSZealous was one of the three ships forming the second group of wooden steam battleships selected in 1860 for conversion to ironclads. This was done in response to the perceived threat to Britain offered by the large French ironclad building programme. The ship was ordered to the West Coast of Canada after she was completed to represent British interests in the Eastern Pacific Ocean. Zealous became the flagship for the Pacific Station for six years until she was relieved in 1872. She was refitted upon her arrival and subsequently became the guard ship at Southampton until she was paid off in 1875. The ship was in reserve until she was sold for scrap in 1886.
HMS Lord Clyde was the name ship of the wooden-hulled Lord Clyde class of two armoured frigates built for the Royal Navy (RN) during the 1860s. She and her sister ship, Lord Warden, were the heaviest wooden ships ever built and were also the fastest steaming wooden ships in the RN. Lord Clyde was initially assigned to the Channel Fleet in 1866, but was transferred to the Mediterranean Fleet in 1868. The ship suffered engine problems throughout her career and it needed to be replaced after only two years of service. She rejoined the Mediterranean Fleet in 1871, but was badly damaged when she ran aground the next year. When Lord Clyde was under repair, her hull was found to be rotten and she was sold for scrap in 1875.
HMS Lord Warden was the second and last ship of the wooden-hulled Lord Clyde class of armoured frigates built for the Royal Navy (RN) during the 1860s. She and her sister ship, Lord Clyde, were the heaviest wooden ships ever built and were also the fastest steaming wooden ships. They were also the slowest-sailing ironclads in the RN.
The Cerberus-class breastwork monitor was a pair of breastwork monitors built for the Royal Navy in the 1860s.
HMS Collingwood was the lead ship of her class of ironclad battleships built for the Royal Navy during the 1880s. The ship's essential design became the standard for most of the following British battleships. Completed in 1887, she spent the next two years in reserve before she was assigned to the Mediterranean Fleet for the next eight years. After returning home in 1897, the ship spent the next six years as a guardship in Ireland. Collingwood was not significantly damaged during an accidental collision in 1899 and was paid off four years later. The ship was sold for scrap in 1909 and subsequently broken up.
HMS Nile was one of two Trafalgar-class ironclad battleships built for the Royal Navy during the 1880s. Late deliveries of her main guns delayed her commissioning until 1891 and she spent most of the decade with the Mediterranean Fleet. Nile returned home in 1898 and became the coast guard ship at Devonport for five years before she was placed in reserve in 1903. The ship was sold for scrap in 1912 and broken up at Swansea, Wales.
The Bulwark class were the final class of wooden line-of-battle ships laid down for the Royal Navy. They were laid down after HMS Warrior. In March 1861 their construction was suspended, and seven were later converted to iron-clads. HMS Bulwark and HMS Robust were kept on the stocks almost complete, in case of need, until they were scrapped in 1873 and 1872.
HMS Inconstant was an unarmored, iron-hulled, screw frigate built for the Royal Navy in the late 1860s. Upon completion in 1869, she was the fastest warship in the world and was assigned to the Channel Squadron. Two years later the ship was transferred to the Detached Squadron for a brief time before she was paid off into reserve in 1872. Inconstant was recommissioned in 1880 for service with the Flying Squadron that circumnavigated the world in 1880–82. On the return voyage, the ship was diverted to Egypt during the Anglo-Egyptian War of 1882 and played a minor role supporting operations ashore. She was reduced to reserve again after her return and was served as an accommodation ship in 1897. Inconstant was hulked in 1904 and became a training ship in 1906. She continued in that role, under a variety of names, until she was sold for scrap in 1955 and subsequently broken up, the second-to-last surviving Pembroke-built warship in existence.
HMS Royal Oak was one of seven Royal Sovereign-class pre-dreadnought battleships built for the Royal Navy during the 1890s. Upon her completion in 1894, she was initially placed in reserve until mobilised in 1896 for service with the Flying Squadron. After returning briefly to reserve, the ship was assigned the following year to the Mediterranean Fleet. Royal Oak remained there until 1902 when she returned home; after a refit, the ship was assigned to the Home Fleet, where she served as the flagship of the fleet's second-in-command in 1904–05. Royal Oak was then reduced to reserve until she was taken out of service in 1911. The ship was sold for scrap in early 1914.
