Dekabrist Class Submarine
The ''Dekabrist'' class, also known as Series I, were the first class of submarines built for the Soviet Navy after the October Revolution of 1917. They were authorized in the Soviet Naval Shipbuilding Program of 1926, marking the revival of submarine design in Russia. They were authorized in the Soviet Naval Shipbuilding Program of 1926, and began their sea trials in 1930. Of the six vessels built, two survived World War II, and one submarine of the class is now a museum ship. Design and construction A set of performance and design criteria for the new submarine type, known as an "operational-tactical requirement", was formulated in 1923, but converting this into reality posed challenges. The Red Navy of the 1920s retained a respectable submarine fleet and associated practical skills in construction and maintenance, but was lacking in recent design experience. No new Russian submarine design had been brought into production since the ''Bars'' class, the plans for which h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ordzhonikidze Shipyard
The OJSC Baltic Shipyard (''Baltiysky Zavod'', formerly Shipyard 189 named after Grigoriy Ordzhonikidze) (russian: Балтийский завод имени С. Орджоникидзе) is one of the oldest shipyards in Russia and is part of United Shipbuilding Corporation today. It is located in Saint Petersburg in the south-western part of Vasilievsky Island. It is one of the three shipyards active in Saint Petersburg. Together with the Admiralty Shipyard it has been responsible for building many Imperial Russian battleships as well as Soviet nuclear-powered icebreakers. Currently it specializes in merchant ships while the Admiralty yard specializes in diesel-electric submarines. In addition, it is responsible for construction of Russian floating nuclear power stations. History The shipyard was founded in 1856 by the St. Petersburg merchant M. Carr and the Scotsman Murdoch. L. MacPherson. It subsequently became the Carr and MacPherson yard. In 1864 it built two monitors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boris Malinin
Boris Mikhailovich Malinin (1889–1949) (russian: Борис Михайлович Малинин) was a Soviet shipbuilding scientist and graduate of Saint Petersburg Polytechnical Institute. His father was the operatic singer Mikhail Malinin (ru: Михаил Дмитриевич Малинин), his mother was the operatic singer Varvara Nikolskaya (ru: Варвара Константиновна Никольская), and his sister was the famous Soviet navigator Marina Raskova. From 1926 to 1940, he was the chief designer of the majority of Soviet submarines, including the Dekabrist-class, Leninets-class, Shchuka-class, and Malyutka-class. In 1913 at the age of 24, he designed and built the Bars-class submarine ''Volk'' (russian: ВОЛК; Wolf). Later, in May 1916, under the command of Captain Ivan Messer, the ''Volk'' destroyed three German transports. Beginning on November 4, 1926, under Malinin's leadership the Technical Bureau No.4 managed submarine construction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pressure Hull
A submarine hull has two major components, the ''light hull'' and the ''pressure hull''. The light hull (''casing'' in British usage) of a submarine is the outer non-watertight hull which provides a hydrodynamically efficient shape. The pressure hull is the inner hull of a submarine that maintains structural integrity with the difference between outside and inside pressure at depth. Shapes Modern submarines are usually cigar-shaped. This design, already visible on very early submarines, is called a "teardrop hull". It is structurally efficient for withstanding external pressure, and significantly reduces the hydrodynamic drag on the sub when submerged, but decreases the sea-keeping capabilities and increases drag while surfaced. History The concept of an outer hydrodynamically streamlined light hull separated from the inner pressure hull was first introduced in the early pioneering submarine Ictineo I designed by the Spanish inventor Narcís Monturiol in 1859. However, whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Hull
A double hull is a ship hull design and construction method where the bottom and sides of the ship have two complete layers of watertight hull surface: one outer layer forming the normal hull of the ship, and a second inner hull which is some distance inboard, typically by a few feet, which forms a redundant barrier to seawater in case the outer hull is damaged and leaks. The space between the two hulls is sometimes used for storage of ballast water. Double hulls are a more extensive safety measure than double bottoms, which have two hull layers only in the bottom of the ship but not the sides. In low-energy collisions, double hulls can prevent flooding beyond the penetrated compartment. In high-energy collisions, however, the distance to the inner hull is not sufficient and the inner compartment is penetrated as well. Double hulls or double bottoms have been required in all passenger ships for decades as part of the Safety Of Life At Sea or SOLAS Convention. Uses Double hulls ...

Stabilimento Tecnico Triestino
Stabilimento Tecnico Triestino (STT) ("Technical Establishment of Trieste") was a private shipbuilding company based in Trieste from the mid-19th to early 20th century, and the most important naval shipbuilding firm of the Austro-Hungarian Empire. After World War I, Trieste was annexed by Italy and the firm built naval and commercial vessels for its new host country. STT was merged with another Italian shipbuilding firm, Cantiere Navale Triestino, in 1929 to form Cantieri Riuniti dell' Adriatico (CRDA). As CRDA Trieste, its shipyards remained active well into the postwar period, becoming part of the Fincantieri group in 1984. History Austro-Hungarian ownership Stabilimento Tecnico Triestino had its origins in a private shipyard founded by Gaspare Tonello at San Marco, on the coastline west of Trieste, in 1838. In 1857, the shipyard was merged with a local manufacturer of marine steam engine, marine engines to become STT. A second shipyard was also acquired, at San Rocco near the ...

Cantiere Navale Triestino
Cantiere Navale Triestino – abbreviated CNT, or in English Trieste Naval Shipyard – was a private shipbuilding company based at Monfalcone operating in the early 20th century. The yard still functions today, though under a different name. History Cantiere Navale Triestino was founded in 1908 by the Cosulich family. The company was largely Italian, though the site, at Monfalcone, was in what was then the Austro-Hungarian Empire. Up to the outbreak of the First World War CNT had built several ships, both merchant such as and military such as the cruiser ''Saida'' for the Austro-Hungarian Navy (KuK). At the outbreak of war between Italy and Austria in 1915 the largely Italian workforce abandoned the shipyard, while the site itself was too close to the front line to continue to operate. It was occupied by the Italian Army on 8 June 1915 and was under fire from the Austrians from July to September 1915 during the Battle of the Isonzo. The company continued to operate, using fa ...

Pisani-class Submarine
The ''Pisani''-class submarines were built for the (Royal Italian Navy) during the late 1920s. They played a minor role in the Spanish Civil War of 1936–1939 supporting the Spanish Nationalists. Design and description Designed in parallel with the s, the ''Pisani'' class was larger to accommodate more fuel and give them more range. They displaced surfaced and submerged. The submarines were long, had a beam of and a draft of . They had an operational diving depth of . Their crew numbered 48 officers and enlisted men.Chesneau, p. 307 For surface running, the boats were powered by two diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a electric motor. Like the ''Mameli''s, their stability was poor and they had to be modified with bulges after completion. This reduced their speeds from on the surface and underwater to and respectively. On the surface, the ''Pisani'' class had a range of at ; submerged, they had a range o ...

Cantieri Riuniti Dell'Adriatico
Cantieri Riuniti dell'Adriatico ("United Shipbuilders of the Adriatic") was an Italian manufacturer in the sea and air industry which was active from 1930 to 1966. This shipyard is now owned by Fincantieri. History In 1930, Stabilimento Tecnico Triestino based at Trieste merged with another Italian company, the Cantiere Navale Triestino of Monfalcone, forming the ''Cantieri Riuniti dell'Adriatico'' (CRDA). The new company built a number of light and heavy cruisers for the Regia Marina (Royal Italian Navy) between the wars, as well as some 27 submarines. The ocean liner ''Conte di Savoia'' was also constructed in 1932. During the World War II, CRDA Trieste built two battleships for the Regia Marina, ''Vittorio Veneto'' and ''Roma''. CRDA survived the postwar shakeup in the shipbuilding industry and went on to build several more commercial liners in the 1950s and 1960s, as well as a few naval vessels. In 1984, CRDA was sold to the Fincantieri Group. For the Olympic regattas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SM U-42
SM ''U-42'' was a Pacinotti-class submarine laid down on 18 August 1913 in Italy at Società FIAT-San Giorgio, Muggiano, La Spezia. Ordered by the Imperial German Navy the submarine was confiscated by the Italian government on 8 August 1915 after entering war with the Austria-Hungary. Commissioned as ''Balilla'' into the Regia Marina the submarine was sunk off Lissa by Austro-Hungarian torpedo boats ''65 T'' and ''66 T''.

First World War
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
