Submarine
A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or informally to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub). Submarines are referred to as ''boats'' rather than ''ships'' regardless of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and submarines were adopted by several navies. They were first used widely during World War I (1914–1918), and are now used in many navy, navies, large and small. Their military uses include: attacking enemy surface ships (merchant and military) or other submarines; aircraft carrier protection; Blockade runner, blockade running; Ballistic missile submarine, nuclear deterrenc ...

British R-class Submarine
The R-class submarines were a class of 12 small British diesel-electric submarines built for the Royal Navy during World War I, and were forerunners of the modern attack submarine, in that they were designed specifically to attack and sink enemy submarines, their battery capacity and hull shape being optimized for underwater performance. With a submerged speed of , the class set an underwater speed record not broken until the experimental Japanese Submarine No.71 of 1938, which was capable of more than submerged. Description Ordered in December 1917, the R class were designed to be faster underwater than on the surface, achieving a submerged speed of versus a surfaced speed of . They were well-streamlined, having no external ballast tanks, casing, or deck gun, and a streamlined spindle-shaped hull of circular cross-sectionFitzsimons, p.2170, "''R-1''" (not reproduced until the American USS ''Albacore'') which tapered sharply towards the stern and allowed only for a singl ...

Type XXIII Submarine
German Type XXIII submarines were the first so-called elektroboote ("electric boats") to become operational. They were small coastal submarines designed to operate in the shallow waters of the North Sea, Black Sea and Mediterranean Sea, where larger Type XXI electric boats were at risk in World War II. They were so small they could carry only two torpedoes, which had to be loaded externally. As with their far larger sisters—the Type XXI—they were able to remain submerged almost all of the time and were faster than conventional U-boats, due to the improved streamlining of their shape, batteries with larger capacity and the snorkel, which allowed the diesel engines to be used while submerged. The Type XXI and XXIII U-boats revolutionized post-war submarine design. Nearly a thousand Type XXIII boats were projected towards the close of World War II, but most of these were either cancelled, scrapped incomplete, or only projected. Background When development began on the Type XX ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Type XVII Submarine
The Type XVII U-boats were small coastal submarines that used a high-test peroxide propulsion system, which offered a combination of air-independent propulsion and high submerged speeds. Background In the early 1930s Hellmuth Walter had designed a small, high-speed submarine with a streamlined form propelled by high-test peroxide (HTP) and in 1939 he was awarded a contract to build an experimental vessel, the 80 ton , which achieved an underwater speed of during trials in 1940. On 14 November 1941 Admirals Erich Raeder and Werner Fuchs (head of the ''Kriegsmarine''s Construction Office) witnessed a demonstration of the ''V-80'';Rössler (2001), p. 174. Raeder was impressed, but Fuchs was slow to approve further tests. Following the success of the ''V-80's'' trials, Walter contacted Karl Dönitz in January 1942, who enthusiastically embraced the idea and requested that these submarines be developed as quickly as possible. An initial order was placed in summer 1942 for four Typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Type VII Submarine
Type VII U-boats were the most common type of German World War II U-boat. 704 boats were built by the end of the war. The type had several modifications. The Type VII was the most numerous U-boat type to be involved in the Battle of the Atlantic. The lone surviving example, , is on display at the Laboe Naval Memorial located in Laboe, Schleswig-Holstein, Germany. At the start of the Second World War the ''Type VII'' class wastogether with the British ''U'', ''S'' and ''T'' class and Dutch ''O 21'' classone of the most advanced submarine classes in service. Design After the defeat in World War I, the Treaty of Versailles forbade Germany to build submarines. Germany circumvented the treaty by setting up the Dutch dummy company ''NV Ingenieurskantoor voor Scheepsbouw Den Haag'' (I.v.S) which continued to design submarines. Based on the World War I design of the Type UB III and its never-built successors Type UF and Type UG, IVS designed the Vetehinen-class submarine and ...

Archimede-class Submarine
The ''Archimede'' class were a group of four submarines built for the (Royal Italian Navy) in the early 1930s. The boats fought in the Spanish Civil War (under the Nationalist flag) and in World War II. In Spanish service, two boats were known as the ''General Mola'' class; these were taken out of service in 1959. Design The ships were designed by the firm Cavallini and were a partially double hulled design. They were an enlarged version of the with ballast tanks rearranged, greater range, fuel and torpedo capacity for ocean service. Like most of the later ocean-going submarines of the Italian navy, their deck armament consisting of two guns was conceived to deal with armed merchantmen in surface combat. They also mounted two anti-aircraft machine guns. The number of torpedoes was increased from 12 on the ''Settembrini'' class to 16. Boats All boats were built by the shipyard of Franco Tosi at Taranto Taranto (; ; previously called Tarent in English) is a coastal ...

British K-class Submarine
The K-class submarines were a class of steam-propelled submarines of the Royal Navy designed in 1913. Intended as large, fast vessels with the endurance and speed to operate with the Naval fleet, battle fleet, they gained notoriety and the nickname of "Kalamity class" for being involved in many accidents. Of the 18 built, none were lost through enemy action, but six sank, with significant loss of life, in accidents. Only one ever engaged an enemy vessel, ''K-7'' hitting a U-boat amidships, though the torpedo failed to explode with what has been described as typical "K" luck; ''K-7'' escaped retaliation by steaming away at speed. The class found favour with Commodore Roger Keyes, then Inspector Captain of Submarines, and with admirals Sir John Jellicoe, Commander-in-Chief British Grand Fleet, and Sir David Beatty, Commander-in-Chief Battlecruiser Squadrons. An opponent of the class was Admiral John Fisher, 1st Baron Fisher, Jacky Fisher, later First Sea Lord and Chief of the Na ...

HMS Swordfish (1916)
HMS ''Swordfish'' was an experimental submarine built for the Royal Navy before the First World War to meet the Navy's goal of an "overseas" submarine capable of on the surface. Diesel engines of the period were unreliable and not very powerful so steam turbines were proposed instead to meet the RN's requirement. ''Swordfish'' proved to be slower than designed and unstable while surfacing, and consequently she was modified as an anti-submarine patrol vessel in 1917. She was paid off before the end of the war and sold for scrapping in 1922. Design HMS ''Swordfish'' was developed to meet a requirement of Royal Navy's Submarine Committee for a large submarine capable of operating with the fleet at a surfaced speed of . Most of the earlier British submarines had been single-hulled vessels built by Vickers, and the Navy was interested in evaluating other designs. Captain Roger Keyes, Inspecting Captain of Submarines, had previously served as naval attaché in Italy and had kept ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Porpoise-class Submarine
The ''Porpoise'' class was an eight-boat class of diesel-electric submarines operated by the Royal Navy. This class was originally designated patrol submarines, then attack. They were the first conventional British submarines to be built after the end of World War II. Their design was, in many ways, influenced by the German World War II-era Type XXI U-boats. Design The ''Porpoise''-class submarines were larger but shorter than their T-class predecessors and used a much improved steel known as UXW.''Rebuilding the Royal Navy : Warship Design Since 1945'', D. K. Brown and George Moore, Chatham Publishing, 2003, pp.114–115 This, and improved design and construction techniques allowed much deeper diving. It was found in tests that the unusually long engine room was liable to collapse, so there were extra large frames in this section, which proved to be something of an operational inconvenience. Designed with a top speed of , the boats were capable of , or once fitted with sile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British V-class Submarine
The British V-class submarine (officially "U-Class Long hull 1941–42 programme") was a class of submarines built for the Royal Navy during the Second World War. History Forty-two vessels were ordered to this design, all to be built by Vickers-Armstrong at either Barrow-in-Furness or at Walker-on-Tyne, but only 22 were completed. Note that seven of these vessels received 'U' names (conversely, four of the U class had received names beginning with 'V'). The V-class submarines were very similar to the preceding U-class (short-hull) boats, of which they constituted a linear development, but had pressure hull plating instead of for deeper diving, also a lengthened stern The stern is the back or aft-most part of a ship or boat, technically defined as the area built up over the sternpost, extending upwards from the counter rail to the taffrail. The stern lies opposite the bow, the foremost part of a ship. O ... and fining at the bow to reduce noise and improve underw ...

Oruç Reis-class Submarine
The ''Oruç Reis''-class submarines were ordered by the Turkish Navy from the British company Vickers in 1939. They were similar to the British S-class submarines, but slightly smaller. They had the S-class machinery but only four bow torpedo tubes. The four boats were requisitioned by the Royal Navy on the outbreak of World War II and fought in the British fleet as the ''P611'' class. Two submarines were delivered to the Turks in 1942 in order to bolster Turkish strength against the threat from Nazi Germany and the remaining surviving submarine was delivered to the Turkish Navy after the end of the war in 1945. P615 had been sunk in 1943. The three Turkish boats were scrapped in 1957. ''P614'' and ''P615'' appear in the film ''We Dive at Dawn'' as HMS ''Sea Tiger''. Ships All were built by Vickers in Barrow-in-Furness Barrow-in-Furness is a port town and civil parish (as just "Barrow") in the Westmorland and Furness district of Cumbria, England.

British U-class Submarine
The British U-class submarines (officially "War Emergency 1940 and 1941 programmes, short hull") were a class of 49 small submarines built just before and during the Second World War. The class is sometimes known as the ''Undine'' class, after the first submarine built. A further development was the British V-class submarine of 1942. At the start of the Second World War the U class was, with the British S and T-class submarines, the Dutch and German Type VII one of the most advanced submarine classes in service. Background The Royal Navy was limited to no more than of submarines by the London Naval Treaty of 1930. The tonnage limit led to proposals for smaller submarines which was also prompted by trials with larger submarines demonstrating that they were easier to find and lacked manoeuvrability. By coincidence the First World War-vintage H-class submarines used for training in anti-submarine warfare were reaching the end of their useful service. The Rear-Admiral Subma ...
