A heavy cruiser was a type of cruiser, a naval warship designed for long range and high speed, armed generally with naval guns of roughly 203 mm (8 inches) in calibre, whose design parameters were dictated by the Washington Naval Treaty of 1922 and the London Naval Treaty of 1930. The heavy cruiser is part of a lineage of ship design from 1915 through the early 1950s, although the term "heavy cruiser" only came into formal use in 1930. The heavy cruiser's immediate precursors were the light cruiser designs of the 1900s and 1910s, rather than the armoured cruisers of the years before 1905. When the armoured cruiser was supplanted by the battlecruiser, an intermediate ship type between this and the light cruiser was found to be needed—one larger and more powerful than the light cruisers of a potential enemy but not as large and expensive as the battlecruiser so as to be built in sufficient numbers to protect merchant ships and serve in a number of combat theatres.
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.
The Queen Elizabeth-class battleships were a group of five super-dreadnoughts built for the Royal Navy during the 1910s. These battleships were superior in firepower, protection and speed to their Royal Navy predecessors of the Iron Duke class as well as preceding German classes such as the König class. The corresponding Bayern-class ships were generally considered competitive, although the Queen Elizabeth class were 2 knots (3.7 km/h) faster and outnumbered the German class 5:2. The Queen Elizabeths are generally considered the first fast battleships of their day.
HMS Jupiter was a J-class destroyer of the Royal Navy.
HMS Courageous was the lead ship of her class of three battlecruisers built for the Royal Navy in the First World War. Designed to support the Baltic Project championed by First Sea Lord John Fisher, the ship was very lightly armoured and armed with only a few heavy guns. Courageous was completed in late 1916 and spent the war patrolling the North Sea. She participated in the Second Battle of Heligoland Bight in November 1917 and was present when the German High Seas Fleet surrendered a year later.
HMS Anson was a King George V-class battleship of the Royal Navy, named after Admiral George Anson. She was built by Swan Hunter and Wigham Richardson Shipyard on the River Tyne and launched on 24 February 1940, being completed on 22 June 1942. Her completion was delayed to allow the fitting of fire-control radar and additional anti-aircraft weapons. She was originally to have been named Jellicoe, but was renamed Anson in February 1940.
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 a Royal Navy battleship, the design of which revolutionised naval power. The ship's entry into service in 1906 represented such an advance in naval technology that her name came to be associated with an entire generation of battleships, the dreadnoughts, as well as the class of ships named after her. Likewise, the generation of ships she made obsolete became known as pre-dreadnoughts. Admiral Sir John "Jacky" Fisher, First Sea Lord of the Board of Admiralty, is credited as the father of Dreadnought. Shortly after he assumed office in 1904, he ordered design studies for a battleship armed solely with 12 in (305 mm) guns and a speed of 21 knots. He convened a Committee on Designs to evaluate the alternative designs and to assist in the detailed design work.
HMS Agincourt was a dreadnought battleship built in the United Kingdom in the early 1910s. Originally part of Brazil's role in a South American naval arms race, she holds the distinction of mounting more heavy guns (fourteen) and more turrets (seven) than any other dreadnought battleship, in keeping with the Brazilians' requirement for an especially impressive design.
ORP Piorun was an N-class destroyer operated by the Polish Navy in World War II. The word piorun is Polish for "Thunderbolt". Ordered by the Royal Navy in 1939, the ship was laid down as HMS Nerissa before being loaned to the Poles in October 1940 while still under construction.
HMS Monarch was the first seagoing British warship to carry her guns in turrets, and the first British warship to carry guns of 12-inch (300 mm) calibre.
The two ships of the Belleisle class, HMS Belleisle and HMS Orion, originally built in Britain for the Ottoman Navy, were taken over by the Royal Navy in 1878.
HMS Orion was a Belleisle-class ironclad of the Victorian Royal Navy. Originally constructed for the Ottoman Empire, and called Bourdjou-Zaffer, she was purchased by the British Government before completion.
HMS Superb was an ironclad battleship designed by Sir Edward Reed for the Ottoman Navy, and was built in Britain by Thames Ironworks under the name of Hamidieh. She had both engines and sails.
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.
HMS Anson was the last of six Admiral-class ironclad battleships built for the Royal Navy during the 1880s. The ship was completed, except for her armament, in 1887, but had to wait two years for her guns to be installed. She was assigned to the Channel Fleet in mid-1889 as a flagship for the fleet's second-in-command. Two years later, the passenger ship SS Utopia sank with the loss of 562 lives after colliding with Anson in the Bay of Gibraltar. In mid-1893, Anson was transferred to the Mediterranean Fleet, subsequently returning home in 1900 when she was assigned to the Reserve Fleet. She recommissioned for the Home Fleet in early 1901. Anson was paid off three years later and then sold for scrap in 1909.
HMS Benbow was a Victorian era Admiral-class battleship of the British Royal Navy, named for Admiral John Benbow. Completed in 1888, Benbow spent the majority of her career in reserve with only brief spurts as part of the active fleet. The battleship was scrapped in 1909.
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 Barfleur was the second and last of the Centurion-class pre-dreadnought battleships built for the Royal Navy in the 1890s. Intended for service abroad, they exchanged heavy armour and a powerful armament for high speed and long range to counter the foreign armoured cruisers then being built as commerce raiders and were rated as second-class battleships.
