Sirena-class Submarine
The ''Sirena''-class submarines were the second sub-class of the 600 Series of coastal submarines built for the (Royal Italian Navy) during the early 1930s. Of the dozen boats built of this class, only one survived World War II. Design and description The ''Sirena'' class was an improved and enlarged version of the preceding s. They displaced surfaced and submerged. The submarines were long, had a beam of and a draft of . Their crew numbered 45 officers and enlisted men.Chesneau, p. 309 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. They could reach on the surface and underwater. On the surface, the ''Sirena'' class had a range of at ; submerged, they had a range of at .Bagnasco, p. 148 The boats were armed with six torpedo tubes, four in the bow and two in the stern for which they carried a total of 12 torpedoes. They were also armed with a single ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion o ...

Draft (hull)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Italian Submarines Of World War II
The Italian submarine fleet of World War II was the largest in the world at the time, with 116 submarines. It saw action during the Second World War, serving mainly in the Mediterranean. During the conflict 88 submarines, some two-thirds of its total strength, were lost. Construction history The submarine fleet available to the Italian Royal Navy (the ''Regia Marina'') in World War II was the product of a long term build-up during the interwar years, despite the prevailing economic and political pressures of the period. After World War I Italy had a fleet of 47 submarines in various classes; these were mostly obsolescent and she was interested in replacing them. To this end the ''Regia Marina'' made plans for a fleet of vessels in three Types: *Type I ocean-going: *Type 2 coastal/sea-going; *Type 3 mine layers. *The Navy also invested time and resources in midget submarines and underwater special forces. At the same time the major powers were negotiating an arms limitation tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiume
Rijeka ( , , ; also known as Fiume hu, Fiume, it, Fiume ; local Chakavian: ''Reka''; german: Sankt Veit am Flaum; sl, Reka) is the principal seaport and the third-largest city in Croatia (after Zagreb and Split). It is located in Primorje-Gorski Kotar County on Kvarner Bay, an inlet of the Adriatic Sea and in 2021 had a population of 108,622 inhabitants. Historically, because of its strategic position and its excellent deep-water port, the city was fiercely contested, especially between the Holy Roman Empire, Italy and Croatia, changing rulers and demographics many times over centuries.

Taranto
Taranto (, also ; ; nap, label= Tarantino, Tarde; Latin: Tarentum; Old Italian: ''Tarento''; Ancient Greek: Τάρᾱς) is a coastal city in Apulia, Southern Italy. It is the capital of the Province of Taranto, serving as an important commercial port as well as the main Italian naval base. Founded by Spartans in the 8th century BC during the period of Greek colonisation, Taranto was among the most important in Magna Graecia, becoming a cultural, economic and military power that gave birth to philosophers, strategists, writers and athletes such as Archytas, Aristoxenus, Livius Andronicus, Heracleides, Iccus, Cleinias, Leonidas, Lysis and Sosibius. By 500 BC, the city was among the largest in the world, with a population estimated up to 300,000 people. The seven-year rule of Archytas marked the apex of its development and recognition of its hegemony over other Greek colonies of southern Italy. During the Norman period, it became the capital of the Principality of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 regatta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scuttling
Scuttling is the deliberate sinking of a ship. Scuttling may be performed to dispose of an abandoned, old, or captured vessel; to prevent the vessel from becoming a navigation hazard; as an act of self-destruction to prevent the ship from being captured by an enemy force (or, in the case of a vessel engaged in illegal activities, by the authorities); as a blockship to restrict navigation through a channel or within a harbor; to provide an artificial reef for divers and marine life; or to alter the flow of rivers. Notable historical examples Skuldelev ships (around 1070) The Skuldelev ships, five Viking ships, were sunk to prevent attacks from the sea on the Danish city of Roskilde. The scuttling blocked a major waterway, redirecting ships to a smaller one that required considerable local knowledge. Cog near Kampen (early 15th century) In 2012, a cog preserved from the keel up to the decks in the silt was discovered alongside two smaller vessels in the river IJssel ...

Anti-aircraft Warfare
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircraft ...
