Glauco-class Submarine
The ''Glauco'' class was a pair of submarines ordered by the Portuguese government, but were taken over and completed for the (Royal Italian Navy) during the 1930s. They played a minor role in the Spanish Civil War of 1936–1939 supporting the Spanish Nationalists. Design and description The ''Glauco''-class submarines were improved versions of the preceding . They displaced surfaced and submerged. The submarines were long, had a beam of and a draft of .Chesneau, p. 305 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 ''Glauco'' class had a range of at ; submerged, they had a range of at .Bagnasco, p. 150 The boats were armed with eight internal torpedo tubes, four each in the bow and stern. They carried a total of 14 torpedoes. They were also armed with two deck guns, one e ... [...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 cruiser, light and heavy cruisers for the Regia Marina (Royal Italian Navy) between the wars, as well as some 27 submarines. The ocean liner SS Conte di Savoia, ''Conte di Savoia'' was also constructed in 1932. During the World War II, CRDA Trieste built two battleships for the Regia Marina, Italian battleship Vittorio Veneto, ''Vittorio Veneto'' and Italian battleship Roma (1940), ''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 a ...

Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cor ...

Submarine Classes
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 of ...

Allies Of World War II
The Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during the Second World War (1939–1945) to oppose the Axis powers, led by Nazi Germany, Imperial Japan, and Fascist Italy. Its principal members by 1941 were the United Kingdom, United States, Soviet Union, and China. Membership in the Allies varied during the course of the war. When the conflict broke out on 1 September 1939, the Allied coalition consisted of the United Kingdom, France, and Poland, as well as their respective dependencies, such as British India. They were soon joined by the independent dominions of the British Commonwealth: Canada, Australia, New Zealand and South Africa. Consequently, the initial alliance resembled that of the First World War. As Axis forces began invading northern Europe and the Balkans, the Allies added the Netherlands, Belgium, Norway, Greece, and Yugoslavia. The Soviet Union, which initially had a nonaggression pa ...

Scuttled
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 in t ...

HMS Wishart (D67)
HMS ''Wishart'' (D67) was a Modified W-class destroyer of the British Royal Navy that saw service in World War II. She spent most of her wartime career based at Gibraltar, engaged in convoy defence, but also served in various naval and military operations in the Mediterranean Sea. Construction and commissioning ''Wishart'', the first Royal Navy ship of the name, was ordered in January 1918 as part of the 13th Order of the 1918–1919 Naval Programme, and was laid down on 18 May 1918 by John I. Thornycroft & Company at Woolston, Hampshire. The pace of her construction slowed after the Armistice with Germany brought World War I to an end on 11 November 1918, but she was launched on 18 July 1919 and completed in June 1920. Service history Interwar Upon completion, ''Wishart'' was commissioned in June 1920. During the interwar period she served first in the Atlantic Fleet and then in the Mediterranean Fleet, and while in the latter had Lord Louis Mountbatten ...
