Wicher-class Destroyer
The ''Wicher''-class destroyers were a series of destroyers that served in the Polish Navy during World War II. Two ships of this class were built for the Second Polish Republic by Chantiers Navals Français during the late 1920s. They were modified versions of the s built for the French Navy. History After the World War I, Great War, Poland's shoreline was very short (only ) and there was no need to create a large naval force. Initially consisting merely of four naval trawlers and two Monitor (warship), monitors — all inherited from the ''Kaiserliche Marine'' — in 1924, the Polish Navy was to start the construction of nine submarines. As Poland's greatest possible enemy at that time was perceived to be the Soviet Union, their only task would be to secure supply convoys from France in case of a war. However, due to the economic crisis and the customs war with Germany, this plan had to be abandoned and eventually only three submarines were ordered from France. At t ...

Chantiers Navals Français
Chantiers Navals Français was a French shipbuilding company founded in 1917 located in Blainville-sur-Orne in the port of Caen. The company mainly built merchant ships but also built destroyers and submarines for the French Navy between 1924 and 1933 and the destroyers and ORP Burza for the Polish Navy. The yard closed in 1954. References {{France-stub Shipyards of France ... [...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 Autonomous underwater vehicle, 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 navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

Superstructure
A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of physical structures such as buildings, bridges, or ships. Aboard ships and large boats On water craft, the superstructure consists of the parts of the ship or a boat, including sailboats, fishing boats, passenger ships, and submarines, that project above her main deck. This does not usually include its masts or any armament turrets. Note that in modern times, turrets do not always carry naval artillery, but they can also carry missile launchers and/or antisubmarine warfare weapons. The size of a watercraft's superstructure can have many implications in the performance of ships and boats, since these structures can alter their structural rigidity, their displacements, and/or stability. These can be detrimental to any vessel's performance if they are taken into consideration incorrectly. The height and the weight of superstructure on board a ship or a bo ...

Watertight Compartment
A compartment is a portion of the space within a ship defined vertically between decks and horizontally between bulkheads. It is analogous to a room within a building, and may provide watertight subdivision of the ship's hull important in retaining buoyancy if the hull is damaged. Subdivision of a ship's hull into watertight compartments is called compartmentation. History Bulkhead watertight compartments were originally invented by the Chinese. These compartments strengthened the junks and slowed flooding in case of holing during the Han and Song dynasties. The wide application of Chinese watertight compartments soon spread to the Europeans through the Indian and Arab merchants. The economics of early unsinkable passenger ships was scrutinized in an 1882 Scientific American article. Watertight subdivision Watertight subdivision limits loss of buoyancy and freeboard in the event of damage, and may protect vital machinery from flooding. Most ships have some pumping capacit ...

Funnel (ship)
A funnel is the smokestack or chimney on a ship used to expel boiler steam and smoke or engine exhaust. They are also commonly referred to as stacks. Purpose The primary purpose of a ship's funnel(s) is to lift the exhaust gases clear of the deck, in order not to foul the ship's structure or decks, and to avoid impairing the ability of the crew to carry out their duties. In steam ships the funnels also served to help induce a convection draught through the boilers. Design Since the introduction of steam-power to ships in the 19th century, the funnel has been a distinctive feature of the silhouette of a vessel, and used for recognition purposes. Funnel area The required funnel cross-sectional area is determined by the volume of exhaust gases produced by the propulsion plant. Often this area is too great for a single funnel. Early steam vessels needed multiple funnels ( had 5 when launched), but as efficiency increased new machinery needed fewer funnels. Merchant ships ...

Bourrasque Class Destroyer
The ''Bourrasque'' classalso known as ''Simoun'' class from the first ship completed was a group of twelve French Navy destroyers (''torpilleur'') laid down in 1923 and in service from 1926 to 1950. Along with the heavier , they were part of a plan to modernise the French fleet after the First World War. The ''Bourrasque''s were smaller and slower than the ''Chacal''s, but were nonetheless comparable with the British W class. The class saw varied service in the Second World War, in five different navies, on both sides. These ships were named after types of wind. The design was used as the basis for the two s built for the Polish Navy during the late 1920s. Design and description The ''Bourrasque'' class had an overall length of , a beam of , and a draft of . The ships displaced at ( standard) load and at deep load. They were powered by two geared steam turbines, each driving one propeller shaft, using steam provided by three du Temple boilers. The turbines were designe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Credit (finance)
Credit (from Latin verb ''credit'', meaning "one believes") is the trust which allows one party to provide money or resources to another party wherein the second party does not reimburse the first party immediately (thereby generating a debt), but promises either to repay or return those resources (or other materials of equal value) at a later date. In other words, credit is a method of making reciprocity formal, legally enforceable, and extensible to a large group of unrelated people. The resources provided may be financial (e.g. granting a loan), or they may consist of goods or services (e.g. consumer credit). Credit encompasses any form of deferred payment. Credit is extended by a creditor, also known as a lender, to a debtor, also known as a borrower. Etymology The term "credit" was first used in English in the 1520s. The term came "from Middle French crédit (15c.) "belief, trust," from Italian credito, from Latin creditum "a loan, thing entrusted to another," from pa ...

Władysław Grabski
Władysław Dominik Grabski (; 7 July 1874 – 1 March 1938) was a Polish National Democratic politician, economist and historian. He was the main author of the currency reform in the Second Polish Republic and served as Prime Minister of Poland in 1920 and from 1923 to 1925. He was the brother of Stanisław Grabski and Zofia Kirkor-Kiedroniowa. He was responsible for the creation of the Bank of Poland and implementing the zloty. Grabski's cabinet became the longest standing cabinet in interwar Poland. At the same time, however, Grabski's cabinet was severely criticized. Stanisław Głąbiński, for example, criticized Grabski's inefficiencies in the sphere of international relations, and Wincenty Witos disapproved of Grabski's deficient agricultural reform, as well as his inability to inform the public of the state's real financial situation. Life Władysław Grabski was born in 1874, in a family manor in Borów (a part of Gmina Bielawy) near Łowicz, Congress Poland, Russ ...
