Fleet Submarine
A fleet submarine is a submarine with the speed, range, and endurance to operate as part of a navy's battle fleet. Examples of fleet submarines are the British First World War era K class and the American World War II era ''Gato'' class. The term has survived in Britain to refer to modern nuclear-powered attack submarines. In the United States Navy, the term came to be used primarily for the long-range submarines that served in World War II. Examples United States The term was used by the United States Navy to distinguish submarines suitable for long range patrols in the Pacific Ocean from earlier classes such as the United States S-class submarines. The initial goal, pursued with frequent interruptions since the ''AA-1''-class (aka ''T''-class) launched 1918–19, was to produce a submarine with a surfaced speed of 21 knots to operate with the Standard-type battleships of the surface fleet. Most of the nine " V-boats" launched 1924-33 (''V-1'' through ''V-6'') were either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Washington Naval Treaty
The Washington Naval Treaty, also known as the Five-Power Treaty, was a treaty signed during 1922 among the major Allies of World War I, which agreed to prevent an arms race by limiting naval construction. It was negotiated at the Washington Naval Conference, held in Washington, D.C., from November 1921 to February 1922, and it was signed by the governments of Great Britain, the United States, France, Italy, and Japan. It limited the construction of battleships, battlecruisers and aircraft carriers by the signatories. The numbers of other categories of warships, including cruisers, destroyers, and submarines, were not limited by the treaty, but those ships were limited to 10,000 tons displacement each. The treaty was concluded on February 6, 1922. Ratifications of that treaty were exchanged in Washington on August 17, 1923, and it was registered in the '' League of Nations Treaty Series'' on April 16, 1924. Later naval arms limitation conferences sought additional limitations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River-class Submarine
The River class, or ''Thames'' class, were a class of submarines built for the Royal Navy. Operating during the Second World War, the three boats of the class comprised , and . All the submarines were named after rivers in the United Kingdom. One was lost during the war and the rest taken out of service following it. Design The River class was the last attempt by the Admiralty to produce "fleet submarines", submarines fast enough to operate as part of a fleet, which at the time meant being able to manage somewhere around while surfaced. The previous attempts had been the steam powered K-class submarines and the large gunned M-class submarines. The M class were K-class hulls re-engined with diesels and modified to take a single naval gun directly forward of the conning tower. A design was drawn up in the late 1920s and three vessels were built by Vickers in Barrow: ''Thames'' in 1932, and ''Severn'' and ''Clyde'' in 1935. The latter two were a little larger than ''Tham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 Jacky Fisher, later First Sea Lord, who on the class' suggestion in 1913 had responded 'The m ...

Capital Ship
The capital ships of a navy are its most important warships; they are generally the larger ships when compared to other warships in their respective fleet. A capital ship is generally a leading or a primary ship in a naval fleet. Strategic implications There is usually no formal criterion for the classification, but it is a useful concept in naval strategy; for example, it permits comparisons between relative naval strengths in a theatre of operations without the need for considering specific details of tonnage or gun diameters. A notable example of this is the Mahanian doctrine, which was applied in the planning of the defence of Singapore in World War II, where the Royal Navy had to decide the allocation of its battleships and battlecruisers between the Atlantic and Pacific theatres. The Mahanian doctrine was also applied by the Imperial Japanese Navy, leading to its preventive move to attack Pearl Harbor and the battleships of the U.S. Pacific Fleet. The naval nature o ...

Deck Gun
A deck gun is a type of naval artillery mounted on the deck of a submarine. Most submarine deck guns were open, with or without a shield; however, a few larger submarines placed these guns in a turret. The main deck gun was a dual-purpose weapon used to sink merchant shipping or shell shore targets, or defend the submarine on the surface from enemy aircraft and warships. Typically a crew of three operated the gun, while others were tasked with supplying ammunition. A small locker box held a few 'ready-use' rounds. With a well-drilled, experienced crew, the rate of fire of a deck gun could be 15 to 18 aimed shots per minute. Some submarines also had additional deck guns like auto-cannons and machine guns for anti-aircraft defense. While similar unenclosed guns are often found on surface warships as secondary or defensive armament (such as the US Navy's 5-inch (127 mm)/25 caliber gun which was removed from battleships to mount on submarines), the term "deck gun" normally r ...

Kaichū Type Submarine
The submarines were double-hulled medium-sized submarines of the Imperial Japanese Navy during World War II. They were derived from the . Several variants existed. From 1934 to 1944, the K6 type (''Ro-33'' Class) and the K7 type (Senchū, ''Ro-35'' Class) were built. They were equipped with a L/40 gun and four 53 cm torpedo tubes for ten type 95 Long Lance torpedoes. Most of these submarines were destroyed in combat, suffering from Allied anti-submarine warfare measures, and only survived the war. Class variants The ''Kaichū'' type submarines were divided into seven classes: * * * * * * * ''Kaichū I (Ro-11 class)'' Project number S7. In 1910s, the Imperial Japanese Navy (IJN) bought a license of Schneider-Laubeuf design submarine. The IJN used the design as model and built the ''S Type (Schneider Type)'' submarine, the and . The ''Kaichū I'' is the submarine which jumboized the ''S Type'' submarines. *Boats in class ''Kaichū II (Ro-13 class)'' Project ...

Kaidai-class Submarine
The was a type of first-class submarine operated by the Imperial Japanese Navy (IJN) before and during World War II. The type name was shortened to Navy Large Type Submarine. All ''Kaidai''-class submarines originally had a two-digit boat name, from ''I-51'' onwards. On 20 May 1942, all Kaidai submarines added a '1' to their names. For example, ''I-52'' became ''I-152''. Ships are listed by the three-digit boat name if they had one, two-digit if they were not granted one or left service before 20 May 1942. Class variants The ''Kaidai''-type submarines were divided into seven classes and two subclasses: * * * * * * * * * Kaidai I (''I-51'' class) Project number S22. The prototype for the class. The sole Kaidai I, ''I-51'', was based on World War I-era German submarines. She was completed in 1924, refitted with new engines in 1932 and scrapped in 1941. ''I-51'' never saw combat. *Boat in class Kaidai II (''I-152'' class) Project number S25. There was only 1 Kaidai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mackerel-class Submarine
The ''Mackerel''-class submarines were a pair of experimental prototype submarines built just prior to World War II and launched in 1940 and 1941. The two submarines were similar in size and capability to the United States S-class submarine, S-class submarines built at the end of World War I, and had been ordered to test the feasibility of using mass production techniques to build small submarines. Until at least 1940 it was thought that mass production of fleet submarines would be impractical, and in any case small submarines could provide area defense for submarine bases. Once it became apparent that there would be sufficient production of the more capable s, interest in the design waned and no additional small submarines were ordered. Submarine production standardized during the war on the ''Gato'' class and its successors, the and submarines. In some references, the ''Mackerel''s are called the "M class". Design The ''Mackerel''s stemmed from design studies ordered by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation 'prototypical'. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes. The word ''prototype'' derives from the Greek , "primitive form", neutral of , "original, primitive", from πρῶτ� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sargo-class Submarine
The ''Sargo''-class submarines were among the first United States submarines to be sent into action after the Japanese attack on Pearl Harbor, starting war patrols the day after the attack, having been deployed to the Philippines in late 1941. Similar to the previous , they were built between 1937 and 1939. With a top speed of 21 knots, a range of (allowing patrols in Japanese home waters), and a reliable propulsion plant, along with the ''Salmon''s they were an important step in the development of a true fleet submarine. In some references, the ''Salmon''s and ''Sargo''s are called the "New S Class", 1st and 2nd Groups. The ''Sargo''-class submarine had the distinction of being the first US Navy submarine to sink a Japanese ship in World War II. Design In most features the ''Sargo''s were a repeat of the ''Salmon''s, except for the return to full diesel-electric drive for the last four boats and the adoption of the improved ''Sargo'' battery design.
