Austro-Hungarian Submarine U-XXXII
SM ''U-32'' or ''U-XXXII'' was a ''U-27'' class U-boat or submarine for the Austro-Hungarian Navy. ''U-32'', built by the Hungarian firm of Ganz Danubius at Fiume, was launched in May 1917 and commissioned in June. ''U-32'' had a single hull and was just over in length. She displaced nearly when surfaced and over when submerged. Her two diesel engines moved her at up to on the surface, while her twin electric motors propelled her at up to while underwater. She was armed with two bow torpedo tubes and could carry a load of up to four torpedoes. She was also equipped with a deck gun and a machine gun. In her service career ''U-32'' hit five ships of , sinking four and damaging one. At Pola at war's end, the boat was handed over to Italy and scrapped in 1920. Design and construction Austria-Hungary's U-boat fleet was largely obsolete at the outbreak of World War I.Gardiner, p. 341.

Ganz Danubius
The Ganz Works or Ganz ( or , ''Ganz companies'', formerly ''Ganz and Partner Iron Mill and Machine Factory'') was a group of companies operating between 1845 and 1949 in Budapest, Hungary. It was named after Ábrahám Ganz, the founder and the manager of the company. It is probably best known for the manufacture of tramcars, but was also a pioneer in the application of three-phase alternating current to electric railways. Ganz also made ships (''Ganz Danubius''), bridge steel structures (''Ganz Acélszerkezet'') and high-voltage equipment (''Ganz Transelektro''). In the early 20th century the company experienced its heyday, it became the third largest industrial enterprise in Kingdom of Hungary after the ''Manfréd Weiss Steel and Metal Works'' and the ''MÁVAG'' company. Since 1989, various parts of ''Ganz'' have been taken over by other companies. History Before 1919, the company built ocean liners, dreadnought type battleships and submarines, power plants, automobiles and ...

Austria-Hungary
Austria-Hungary, often referred to as the Austro-Hungarian Empire,, the Dual Monarchy, or Austria, was a constitutional monarchy and great power in Central Europe between 1867 and 1918. It was formed with the Austro-Hungarian Compromise of 1867 in the aftermath of the Austro-Prussian War and was dissolved shortly after its defeat in the First World War. Austria-Hungary was ruled by the House of Habsburg and constituted the last phase in the constitutional evolution of the Habsburg monarchy. It was a multinational state and one of Europe's major powers at the time. Austria-Hungary was geographically the second-largest country in Europe after the Russian Empire, at and the third-most populous (after Russia and the German Empire). The Empire built up the fourth-largest machine building industry in the world, after the United States, Germany and the United Kingdom. Austria-Hungary also became the world's third-largest manufacturer and exporter of electric home appliances, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 ...

Saddle Tank (submarine)
Saddle tanks are a type of ballast tank configuration fitted to submarines. Saddle tanks are fitted in pairs external to the pressure hull, one on each side, in a similar manner to that of a horse's saddle-bags, the positioning of which they resemble in appearance. Development The first effective submarines, those of World War I, had hulls that were broadly circular in cross-section, with a deck plate mounted midway. Their heavy battery tanks were mounted beneath this deck, for stability. The ballast tanks were mounted ''inside'' the pressure hull. For compactness the ballast tanks were wrapped around the batteries, low down and sharing the flat surfaces of the battery tank. The Kingston valves linking the ballast tanks to the sea could be left open, a practice known as "riding the valves", and the water level in the tanks controlled solely by the vent and blowing air valves. The drawback was that the ballast tanks, open to sea pressure, had a flat surface to the crew compartm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bremen
Bremen (Low German also: ''Breem'' or ''Bräm''), officially the City Municipality of Bremen (german: Stadtgemeinde Bremen, ), is the capital of the German state Free Hanseatic City of Bremen (''Freie Hansestadt Bremen''), a two-city-state consisting of the cities of Bremen and Bremerhaven. With about 570,000 inhabitants, the Hanseatic city is the 11th largest city of Germany and the second largest city in Northern Germany after Hamburg. Bremen is the largest city on the River Weser, the longest river flowing entirely in Germany, lying some upstream from its mouth into the North Sea, and is surrounded by the state of Lower Saxony. A commercial and industrial city, Bremen is, together with Oldenburg and Bremerhaven, part of the Bremen/Oldenburg Metropolitan Region, with 2.5 million people. Bremen is contiguous with the Lower Saxon towns of Delmenhorst, Stuhr, Achim, Weyhe, Schwanewede and Lilienthal. There is an exclave of Bremen in Bremerhaven, the "Citybremian Overseas Port ...

AG Weser
Aktien-Gesellschaft „Weser" (abbreviated A.G. „Weser”) was one of the major German shipbuilding companies, located at the Weser River in Bremen. Founded in 1872 it was finally closed in 1983. All together, A.G. „Weser" built about 1,400 ships of different types, including many warships. A.G. „Weser" was the leading company in the Deutsche Schiff- und Maschinenbau AG, a cooperation of eight German shipbuilding companies between 1926 and 1945. History Founding of A.G. „Weser” Aktien-Gesellschaft „Weser” - short A.G. „Weser” - was founded as a successor of the 1843 founded Eisengiesserei & Maschinenbau-Anstalt Waltjen und Leonhard,. This company with its premises was situated on an area called ''Stephanikirchenweide'' at the periphery of the ancient town of Bremen. It was an iron-foundry and machine factory with a wide-ranging production volume of iron-made parts as bridges, cranes, floodgates, steam boiler, steam engines etc. In 1846 Mr. Leonhard left the ...

German Type UB II Submarine
The UB II type submarine was a class of U-boat built during World War I by the German Imperial Navy. They were enlarged from the preceding type UB I and were more effective vessels. The boats were a single hull design with a 50-metre maximum diving depth and a 30-45 second diving time. In 1915 and 1916, 30 were built at two different shipyards. The design of type UB II addressed many of the problems apparent in the preceding type UB I class. The UB II boats featured a two-shaft drive with a much larger battery capacity and larger engines. Storage batteries were placed forward of the central diving tanks to compensate for the much heavier engine installation. The armament of the type UB II consisted of 50 cm G torpedoes launched from two bow tubes. The torpedo tubes were installed one above the other to allow for a bow design that would create optimal surface efficiency. A 5 cm gun was provided on the deck for surface use. The weight of the boat was increased to 270 ton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Havmanden Class Submarine (1911)
The ''Havmanden'' class was a class of six submarines built for the Royal Danish Navy from 1911 to 1914. Also later known as the A class, the boats were designed by the Austro-Hungarian firm Whitehead & Co. of Fiume. The first three submarines were built by the company, while the remaining three were constructed under license in Copenhagen. The boats were just over long and their armament consisted of two bow torpedo tubes, later supplemented with an machine gun. The boats had a single shaft and were propelled by a Fiat or M.A.N. diesel engine on the surface and two electric motors while submerged. Although there was at least one close call for the class leader during World War I, none of the six boats was sunk in service. All six boats of the class remained active in the Royal Danish Navy from their time of construction until 1928, when the first two boats were stricken. The remaining boats were all stricken by 1932. The ''Havmanden'' class served as the basis for the Austr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
