Orzeł-class Submarine
The ''Orzeł'' class was a short series of submarines built in Dutch shipyards for the Polish Navy in the 1930s. Four submarines were planned but only two were completed. They saw service during World War II. Design Initially the design was to be built in the United Kingdom, but the price proposed was too high and the British Admiralty announced that building a fast submarine with over of surface speed was technically impossible. The two submarines were ordered in De Schelde and Rotterdamse Shipyards, ''(Eagle)'' and ''(Vulture)''. Design was made in cooperation with a team from Polish Navy, and incorporated some features of the earlier Dutch submarine including the external trainable mount. The hull was entirely welded, and all controls were hydraulically operated. The design was made to fulfill the Polish requirements for a multi-purpose vessel, to be used both in the shallow waters of the Baltic Sea and in the high seas. They were among the most modern submersibles in the ... [...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 ...

Troopship
A troopship (also troop ship or troop transport or trooper) is a ship used to carry soldiers, either in peacetime or wartime. Troopships were often drafted from commercial shipping fleets, and were unable land troops directly on shore, typically loading and unloading at a seaport or onto smaller vessels, either tenders or barges. Attack transports, a variant of ocean-going troopship adapted to transporting invasion forces ashore, carry their own fleet of landing craft. Landing ships beach themselves and bring their troops directly ashore. History Ships to transport troops were used in Antiquity. Ancient Rome used the navis lusoria, a small vessel powered by rowers and sail, to move soldiers on the Rhine and Danube. The modern troopship has as long a history as passenger ships do, as most maritime nations enlisted their support in military operations (either by leasing the vessels or by impressing them into service) when their normal naval forces were deemed insufficient fo ...

Rotterdamsche Droogdok Maatschappij
The Rotterdamsche Droogdok Maatschappij (RDM) was the largest pre-World War II shipbuilding and repair company in Rotterdam in the Netherlands, existing from 1902 to 1996. It built 355 mostly major seagoing vessels, 18 of which were submarines. RDM on the Dutch Wikipedia During its existence, the wharf operated 12 floating docks and in its heyday employed 7,000 people at one time. Establishment of the company The Rotterdamsche Droogdok Maatschappij was a successor of the company De Maas, founded in Delfshaven in 1856 by Duncan Christie. Shipbuilder De Maas was located in an area that is now the Saint Job's harbor (Sint Jobshaven) of Rotterdam. This company would have to move in 1905 because the lease on the land would end that year. On 14 February 1899 it therefore bought 4.5 hectares of land in Heijplaat, south of the Meuse for 44,000 guilders. A consortium for a drydock company On 14 April 1899 a consortium was founded by people connected to the harbor of Rotterdam and the ...

Vulture
A vulture is a bird of prey that scavenges on carrion. There are 23 extant species of vulture (including Condors). Old World vultures include 16 living species native to Europe, Africa, and Asia; New World vultures are restricted to North and South America and consist of seven identified species, all belonging to the Cathartidae family. A particular characteristic of many vultures is a bald, unfeathered head. This bare skin is thought to keep the head clean when feeding, and also plays an important role in thermoregulation. Vultures have been observed to hunch their bodies and tuck in their heads in the cold, and open their wings and stretch their necks in the heat. They also urinate on themselves as a means of cooling their bodies. A group of vultures in flight is called a 'kettle', while the term 'committee' refers to a group of vultures resting on the ground or in trees. A group of vultures that are feeding is termed a 'wake'. Taxonomy Although New World vultures and O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ORP Sęp (1938)
ORP ''Sęp'' was an serving in the Polish Navy during World War II. In Polish her name means ''Vulture''. Construction Built at the Dutch shipyard Rotterdamsche Droogdok Maatschappij, she was laid down in November 1936 and launched on 17 October 1938. In early 1939 the Polish team supervising the building of the ship noticed a significant slowdown in her construction, which it attributed to the action of German agents. Because of fears that German pressure on the Netherlands would prevent that country from delivering the ship into Polish hands, it was decided to bring the ship to Poland earlier than scheduled. On 2 April, the ship left for deep water sea trials in Horten, Norway, with a crew of Polish sailors and Dutch technicians, under the Dutch flag. After completing the trials, the Polish crew took control of the ship (against the will of the Dutch technicians on board), raised the Polish flag and left Horten to rendezvous with the Polish destroyer outside the harbou ...

Damen Schelde Naval Shipbuilding
Damen Naval is a Dutch shipyard, and a continuation of the Koninklijke Maatschappij De Schelde, responsible for a number of ships used by the Royal Netherlands Navy. It is owned by the Damen Group. Damen Naval is situated in Vlissingen. History The company was founded October 8, 1875, as the ''NV Koninklijke Maatschappij De Schelde'' (KMS) after shipbuilder Arie Smit had taken over the ''Marine Etablissement'' the wharf owned by the Dutch navy. Besides shipbuilding and repair, the company also builds machines, engines, steam turbines, airplanes, and light-metal products. Koninklijk is a royal title granted by the Monarchy of the Netherlands, Dutch Crown. In 1965 the company merged with the NV Rotterdamsche Droogdok Maatschappij (RDM) and the NV Motorenfabriek Thomassen of De Steeg, which resulted in the founding, on March 4, 1966, of the Rijn-Schelde, Rijn-Schelde Machinefabrieken en Scheepswerven NV (RSMS).

Eagle
Eagle is the common name for many large birds of prey of the family Accipitridae. Eagles belong to several groups of genera, some of which are closely related. Most of the 68 species of eagle are from Eurasia and Africa. Outside this area, just 14 species can be found—2 in North America, 9 in Central and South America, and 3 in Australia. Eagles are not a natural group but denote essentially any kind of bird of prey large enough to hunt sizeable (about 50 cm long or more overall) vertebrates. Description Eagles are large, powerfully-built birds of prey, with heavy heads and beaks. Even the smallest eagles, such as the booted eagle (''Aquila pennata''), which is comparable in size to a common buzzard (''Buteo buteo'') or red-tailed hawk (''B. jamaicensis''), have relatively longer and more evenly broad wings, and more direct, faster flight – despite the reduced size of aerodynamic feathers. Most eagles are larger than any other raptors apart from some vultures. The smalles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Orzeł Incident
The ''Orzeł'' incident occurred at the beginning of World War II in September 1939, when the interned Polish submarine escaped from Tallinn, in neutral Estonia, to the United Kingdom. The Stalinist Soviet Union used the incident as one of the pretexts to justify its eventual military invasion and occupation of Estonia in June 1940. Background ''Orzeł'' was docked at Oksywie when Nazi Germany attacked Poland and began the Second World War. The submarine at first took part in Operation Worek, but withdrew from the Polish coast on 4 September as the situation evolved. Damaged by German minesweepers and leaking oil, it headed for Tallinn, which it reached on 14 September 1939 at about 01:30. Lieutenant-Commander Henryk Kłoczkowski, the commanding officer, was taken to a hospital the next day for treatment of an unidentified illness from which he had been suffering since 8 September. The Hague Convention of 1907 enjoined signatories, including Germany, from interfering with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
