The Orion-class battleships were a group of four dreadnought battleships built for the Royal Navy (RN) in the early 1910s. The first 13.5-inch-gunned (343 mm) battleships built for the RN, they were much larger than the preceding British dreadnoughts and were sometimes termed "super-dreadnoughts". The sister ships spent most of their careers assigned to the 2nd Battle Squadron of the Home and Grand Fleets, sometimes serving as flagships. Aside from participating in the failed attempt to intercept the German ships that had bombarded Scarborough, Hartlepool and Whitby in late 1914, the Battle of Jutland in May 1916 and the inconclusive action of 19 August, their service during World War I generally consisted of routine patrols and training in the North Sea.
HMS Neptune was a dreadnought battleship built for the Royal Navy in the first decade of the 20th century, the sole ship of her class. She was the first British battleship to be built with superfiring guns. Shortly after her completion in 1911, she carried out trials of an experimental fire-control director and then became the flagship of the Home Fleet. Neptune became a private ship in early 1914 and was assigned to the 1st Battle Squadron.
The St Vincent-class battleships were a group of three dreadnought battleships built for the Royal Navy in the first decade of the 20th century. The sister ships spent their entire careers assigned to the Home and Grand Fleets. Aside from participating in the Battle of Jutland in May 1916 and the inconclusive action of 19 August several months later, their service during the First World War generally consisted of routine patrols and training in the North Sea. Vanguard was destroyed in 1917 by a magazine explosion with the near total loss of her crew. The remaining pair were obsolete by the end of the war in 1918, and spent their remaining time either in reserve or as training ships before being sold for scrap in the early 1920s.
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and muzzle-loading smoothbore guns, but the Armstrong breech-loading guns proved unreliable and were ultimately withdrawn from service.
Pre-dreadnought battleships were sea-going battleships built from the mid- to late- 1880s to the early 1900s. Their designs were conceived before the appearance of HMS Dreadnought in 1906 and their classification as "pre-dreadnought" is retrospectively applied. In their day, they were simply known as "battleships" or else more rank-specific terms such as "first-class battleship" and so forth. The pre-dreadnought battleships were the pre-eminent warships of their time and replaced the ironclad battleships of the 1870s and 1880s.
HMS Minotaur was the lead ship of the Minotaur-class armoured frigates built for the Royal Navy during the 1860s. Minotaur took nearly four years between her launching and commissioning because she was used for evaluations of her armament and different sailing rigs.
The Lord Nelson class consisted of a pair of pre-dreadnought battleships built for the Royal Navy in the first decade of the twentieth century. Although they were the last British pre-dreadnoughts, both were completed and commissioned well over a year after HMS Dreadnought had entered service in late 1906. Lord Nelson and Agamemnon were assigned to the Home Fleet when completed in 1908, with the former ship often serving as a flagship. The sister ships were transferred to the Channel Fleet when the First World War began in August 1914. They were transferred to the Mediterranean Sea in early 1915 to participate in the Dardanelles Campaign.
A gun turret is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation.
HMS Defence was the lead ship of the Defence-class armoured frigates ordered by the Royal Navy in 1859. Upon completion in 1862 she was assigned to the Channel Fleet. The ship was paid off in 1866 to be refitted and rearmed and was briefly reassigned to the Channel Fleet when she recommissioned in 1868. Defence had short tours on the North Atlantic and Mediterranean Stations, relieving other ironclads, from 1869 to 1872 before she was refitted again from 1872 to 1874. She became guard ship on the River Shannon when she recommissioned. The ship was transferred to the Channel Fleet again in 1876 and then became guard ship on the River Mersey until 1885. Defence was placed in reserve until 1890, when she was assigned to the mechanical training school in Devonport in 1890. She was renamed Indus when the school adopted that name and served there until sold for scrap in 1935.
The Defence-class ironclads were a class of two warships built for the Royal Navy between 1859 and 1862. 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 withdrawn from service after a few years.
HMS Inflexible was a Victorian ironclad battleship carrying her main armament in centrally placed turrets. The ship was constructed in the 1870s for the Royal Navy to oppose the perceived growing threat from the Italian Regia Marina in the Mediterranean.
HMS Edinburgh was an ironclad battleship of the Colossus class which served in the Royal Navy of the Victorian era. She was the sister ship of HMS Colossus, being started before her but being completed after.
The Conqueror class battleships were ironclad warships which served in the Victorian Royal Navy, and whose main weapon was designed to be the ram.
HMS Hero was the second and final Conqueror-class battleship. She was an ironclad who served in the Victorian Royal Navy.
HMS Howe was an Admiral-class ironclad battleship built for the Royal Navy during the 1880s. The ship was assigned to the Channel Fleet in mid-1890 and was badly damaged when she ran aground in late 1892. After repairs were completed, Howe was transferred to the Mediterranean Fleet in late 1893. She returned home in late 1896 and became a guardship in Ireland. Howe remained there until late 1901 when she was assigned to the Reserve Fleet. The ship was paid off in three years later and then sold for scrap in 1910.
The dreadnought was the predominant type of battleship in the early 20th century. The first of the kind, the Royal Navy's HMS Dreadnought, had such an effect when launched in 1906 that similar battleships built after her were referred to as "dreadnoughts", and earlier battleships became known as pre-dreadnoughts. Her design had two revolutionary features: an "all-big-gun" armament scheme, with an unprecedented number of heavy-calibre guns, and steam turbine propulsion. As dreadnoughts became a crucial symbol of national power, the arrival of these new warships renewed the naval arms race between the United Kingdom and Germany. Dreadnought races sprang up around the world, including in South America, lasting up to the beginning of World War I. Successive designs increased rapidly in size and made use of improvements in armament, armour, and propulsion throughout the dreadnought era. Within five years, new battleships outclassed Dreadnought herself. These more powerful vessels were known as "super-dreadnoughts". Most of the original dreadnoughts were scrapped after the end of World War I under the terms of the Washington Naval Treaty, but many of the newer super-dreadnoughts continued serving throughout World War II.
HMS Renown was a second-class predreadnought battleship built for the Royal Navy in the early 1890s. Intended to command cruiser squadrons operating on foreign stations, the ship served as the flagship of the North America and West Indies Station and the Mediterranean Fleet early in her career. Becoming obsolete as cruiser speeds increased, Renown became a royal yacht and had all of her secondary armament removed to make her more suitable for such duties. She became a stoker's training ship in 1909 and was listed for disposal in 1913. The ship was sold for scrap in early 1914.
HMS Neptune was an ironclad turret ship originally designed and built in Britain for Brazil, but acquired for the Royal Navy in 1878. Modifications to suit the Royal Navy took three years to complete and the ship did not begin her first commission until 1883 with the Channel Fleet. She was transferred to the Mediterranean Fleet in 1885, but refitted in Portsmouth in 1886–87. Neptune then became the coastguard ship for the 1st Class Reserve at Holyhead until 1893 when she was placed in reserve in Portsmouth. While she was being towed to the breakers in 1903, Neptune unintentionally rammed HMS Victory, then serving as a training hulk for the Naval Signal School, collided with HMS Hero, and narrowly missed several other ships. She was scrapped in Germany in 1904.
The two British Devastation-class battleships of the 1870s, HMS Devastation and HMS Thunderer, were the first class of ocean-going capital ship that did not carry sails, and the first which mounted the entire main armament on top of the hull rather than inside it.
