The Queen Elizabeth-class battleships were a group of five super-dreadnoughts built for the Royal Navy during the 1910s. The lead ship was named after Elizabeth I of England. 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 in their day.
HMS Queen Elizabeth was the lead ship of her class of dreadnought battleships built for the Royal Navy in the early 1910s, and was often used as a flagship. She served in the First World War as part of the Grand Fleet, and participated in the inconclusive Action of 19 August 1916. Her service during the war generally consisted of routine patrols and training in the North Sea. She and the other super-dreadnought battleships were the first of their type to be powered by oil instead of coal. Queen Elizabeth later served in several theatres during the Second World War, and was ultimately scrapped in 1948.
HMS Dreadnought was a Royal Navy battleship that revolutionised naval power. Dreadnought's name, and the class of battleships named after her, means "a fearless person". Dreadnought'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, 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.
Leipzig was the lead ship of her class of light cruisers built by the German navy. She had one sister ship, Nürnberg. Leipzig was laid down in April 1928, was launched in October 1929, and was commissioned into the Reichsmarine in October 1931. Armed with a main battery of nine 15 cm (5.9 in) guns in three triple turrets, Leipzig had a top speed of 32 knots.
The Orca-class patrol vessels are a class of eight steel-hulled training and surveillance vessels in service with the Royal Canadian Navy (RCN) at Patrol Craft Training Unit (PCTU) Canadian Forces Base (CFB) Esquimalt. Based on the Australian Pacific-class patrol boat design, all of the Orca vessels were constructed by Victoria Shipyards between November 2004 and November 2008. In addition to carrying the RCN designation of patrol craft training (PCT), the Orca-class are not formally commissioned in the RCN and as such do not possess the Her Majesty's Canadian Ship (HMCS) prefix.
The four Agano-class cruisers were light cruisers operated by the Imperial Japanese Navy. All were named after Japanese rivers. Larger than previous Japanese light cruisers, the Agano-class vessels were fast, but with little protection, and were under-gunned for their size. They participated in numerous actions during World War II.
Combined diesel-electric and gas (CODLAG) is a modification of the combined diesel and gas propulsion system for ships. A variant, called the combined diesel-electric or gas (CODLOG) system, contains the same basic elements but will not allow simultaneous use of the alternative drive sources.
Kashima was the second vessel completed of the three light cruisers in the Katori class, which served with the Imperial Japanese Navy during World War II. The ship was named after the noted Shinto shrine Kashima Jingu in Ibaraki prefecture, Japan.
The Almirante Brown class is a class of warships built in Germany for the Argentine Navy. They were commissioned between 1983 and 1984, after the Falklands War. The class comprises four ships; Almirante Brown, La Argentina, Heroína and Sarandí. They are classified as either frigates or destroyers by different publications. The MEKO 360 type warships are based on modular designs which allow quick changes to the vessel's armaments depending on mission requirements. The modular nature of the construction also allows the ships to be modernized or refitted with greater ease. Six vessels were initially ordered, however two ships were cancelled and replaced with orders for MEKO 140 type hulls.
The Hatsuyuki-class destroyer is a class of destroyer, serving with the Japan Maritime Self-Defense Force (JMSDF). It was the first class of first generation of general-purpose destroyers of the JMSDF.
JDS Wakaba was the former Imperial Japanese Navy ship Nashi, a Tachibana-class destroyer. Nashi was sunk in July 1945, but salvaged in 1954 and refitted to join the Japan Maritime Self-Defense Force in 1956 as Wakaba, later being utilised as a radar trials ship.
The Badr class is a class of corvette built by the United States and operated by the Saudi Navy. The class has been relegated to a coastal defence role following the modernisation of the Saudi fleet. There are four vessels in service; Badr, Al Yarmook, Hitteen and Tabuk.
The Shiratsuyu-class destroyers were a class of ten 1st Class destroyers of the Imperial Japanese Navy in service before and during World War II, during which all ten were sunk.
The Katori-class training cruisers were originally ordered by the Imperial Japanese Navy (IJN) to serve as training ships in the 1937 and 1939 Supplementary Naval budgets. During the Pacific War, they were used as administrative flagships for various fleets, such as submarine command and control, and to command escort squadrons. The ships were upgraded as the war progressed with additional anti-aircraft guns and depth charges.
The Sparviero-class are small hydrofoil missile boats capable of traveling at speeds of 46 knots. They were designed for and formerly used by the Italian Navy. The Japanese 1-go class missile boat is an updated version formerly used by the Japan Maritime Self-Defense Force (JMSDF).
The Uragan-class guard ships were built for the Soviet Navy as small patrol and escort ships. Eighteen were built in the 1930s and served during World War II in all four of the Soviet Fleets: Baltic, Black Sea, Northern and Pacific. Four were lost during the war and the rest remained in service until the late 1950s in various secondary roles. The official Soviet designation was Project 2, Project 4 and Project 39, but they were nicknamed the "Bad Weather Flotilla" by Soviet sailors by virtue of their meteorological names.
Fushimi (伏見) was a river gunboat of the Imperial Japanese Navy, that operated on the Yangtze River in China during the 1940s, and during the Second Sino-Japanese War and World War II.
SMS Sachsen was the third of four Bayern-class battleships built, but never finished, for the German Kaiserliche Marine in the 1910s, sometimes considered to be part of a sub-class with her sister Württemberg. Like the other members of the class, she was to be armed with the same main battery of eight 38 cm (15 in) guns in four gun turrets, but she differed from the other members of her class in her propulsion system. She exchanged the steam turbine on her center propeller shaft in favor of a diesel engine. She was laid down in April 1914 at the Germaniawerft shipyard, but the start of World War I in July slowed work on the ship; she was launched in November 1916, but as resources were diverted to more pressing projects, including U-boat construction, work stopped completely when the ship was about nine months from completion. Some components of her propulsion system were reused in several of the Type U 151 submarines submarines. The Treaty of Versailles that ended the war in June 1919 specified that all warships under construction in Germany were to be destroyed, and Sachsen was accordingly sold for scrap in 1920 and dismantled the following year.
Alpino was a frigate operated by the Italian Navy during the Cold War.
