Castle-class Trawler
The Castle-class minesweeper was a highly seaworthy naval trawler adapted for patrol, anti-submarine warfare and minesweeping duties and built to Admiralty specifications. Altogether 197 were built in the United Kingdom between 1916 and 1919, with others built in Canada, India and later New Zealand. Many saw service in the Second World War. First World War The Castle class originated with the commercial trawler ''Raglan Castle'' of 1915, taken up for Royal Navy service. The design was adapted by Smith's Dock Company Ltd to Admiralty requirements for building in quantity. During World War I, 145 were built in the United Kingdom for the Admiralty. The names of the vessels were derived from the official crew rosters of ships at the Battle of Trafalgar. Non-standard ships included in the class varied between and , with dimensions varying between length and beam. The first standard vessel, ''Nathaniel Cole'', was delivered in May 1917. After the war 52 further ships on order we ...

Castle-class Corvette
The Castle-class corvette was an ocean going convoy escort developed by the United Kingdom during the Second World War. It was the follow-on to the , and designed to be built in shipyards that were producing the Flowers. The Castle-class was a general improvement over the smaller Flowers which were designed for coastal rather than open ocean use. The Castle-class corvettes started appearing in service during late 1943. Background In mid-1939, the Admiralty ordered 175 Flower-class corvettes for protecting shipping on the east coast of Britain. They were designed to be built in large numbers in small shipyards and so not compete with other warships for construction. By the time the Flowers began entering service in late-1940, due to their long range they were required to undertake missions beyond coastal waters.Friedman (2006): page 134Friedman (2006): page 135 The Flowers were unsuited for open-ocean escort missions in the North Atlantic, especially in poor weather; they lac ...

Castle-class Patrol Vessel
The Castle class was a class of British offshore patrol vessels of the Royal Navy. Two ships were constructed and after nearly 30 years service were sold to the Bangladesh Navy in 2010. The Bangladesh Navy upgraded these with more armaments including C-704 anti-ship missiles and sensors. These ships are now reclassified as corvettes by the Bangladesh Navy. Design The Castle class was designed by David K. Brown and was intended as a series of six offshore patrol vessels for the Royal Navy, designed in response to criticism of the previous for insufficient speed, sub-optimal sea-keeping and lack of a flight deck for rescue helicopters. In the event, only two ships were built, and . Both vessels were built by Hall Russell in Aberdeen, Scotland. These had significant improvements over the Island-class – they were 300 tonnes larger, more stable in heavy seas, faster and fitted with a large flight deck capable of supporting a Sea King helicopter. For brief periods, the ships co ...

GWR 4073 Class
The 4073 or Castle Class are 4-6-0 steam locomotives of the Great Western Railway, built between 1923 and 1950. They were designed by the railway's Chief Mechanical Engineer, Charles Collett, for working the company's express passenger trains. They could reach speeds of up to . Background The origins of this highly successful design date back to the Star Class of 1907 which introduced the basic 4-cylinder 4-6-0 layout with long-travel valves and Belpaire firebox that was to become characteristic of Great Western Railway (GWR) express passenger locomotives. The Star class was designed to take the top express trains on the GWR, with 61 in service by 1914, but after World War I there was a need for an improved design. To meet this need, Chief Mechanical Engineer George Churchward had in mind an enlarged Star class design with a standard No.7 boiler, as fitted to his GWR 4700 Class express freight 2-8-0. However, this combination would have taken the axle load over the 20-ton limit ...
