O 19-class Submarine
The ''O 19'' class was a class of two submarines, built for the Royal Netherlands Navy by '' Fijenoord'', Rotterdam. The ships were designed as submarine minelayer for operations in both European and colonies waters. The class comprised ''O 19'' and ''O 20'' and were the first submarines in the world to be equipped with a submarine snorkel that allowed the submarine to run its diesel engines while submerged. The submarines diving depth was . These units were very similar to earlier Polish , with a reduced torpedo battery and 10 vertical mine tubes fitted on each beam. History The two Dutch submarines of the ''O 19''-class, which were built on June 15, 1936 at the yard of Wilton-Fijenoord in Schiedam, deviated in many ways from their predecessors. The boats were first planned as K XIX and K XX (K stands for submarines intended for Dutch Colonies) but during the construction it was decided that they were going to be put on the budget of the Department of War, which resulted in the n ...

Wilton-Fijenoord
Wilton-Fijenoord was a shipbuilding and repair company in Schiedam the Netherlands from 1929 to 1999. Presently, the shipyard of Wilton-Feijnoord is part of Damen Shiprepair Rotterdam. Merger of Wilton and Fijenoord (1929) Wilton-Fijenoord had two predecessors. Wilton's Dok- en Werf Maatschappij was the biggest predecessor of Wilton-Fijenoord, the other was the Shipyard Fijenoord. By the mid 1920s these shipyards had become rather similar. Wilton still had an advantage in ship repair, and Fijenoord was still ahead in ship construction, especially for the navy. The idea for a merger dated as far back as at least 1927. The rationale was that the still profitable Wilton company had a major overcapacity and was spread over two locations. The activities of Fijenoord could just as well be done in Schiedam. A concentration of the combined activities in Schiedam would lead to major cost savings. In 1929 talks led to an agreement for a financial merger between the companies. Shares in Wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HNLMS M-1
SM ''UC-8'' was a German Type UC I minelayer submarine or U-boat in the German Imperial Navy (german: Kaiserliche Marine) during World War I. The U-boat had been ordered by November 1914 and was launched on 6 July 1915. She was commissioned into the German Imperial Navy on 5 July 1915 as SM ''UC-8''."SM" stands for "Seiner Majestät" ( en, His Majesty's) and combined with the ''U'' for ''Unterseeboot'' would be translated as ''His Majesty's Submarine''. Mines laid by ''UC-8'' in her one patrol are not known to have sunk any ships. ''UC-8'' ran aground on the Dutch coast near Terschelling on 4 November 1915. Interned by the Dutch, ''UC-8'' was purchased and commissioned into the Dutch Navy as HNLMS ''M-1''. The submarine was broken up in 1932. Design A German Type UC I submarine, ''UC-8'' had a displacement of when at the surface and while submerged. She had a length overall of , a beam of , and a draught of .

HNLMS O 19
''O 19'', laid down as ''K XIX'', was an of the Royal Netherlands Navy that saw service during World War II. ''O 19'', along with her sister ship , were the first submarines in the world to be equipped with a submarine snorkel that allowed the submarine to run its diesel engines while submerged. Ship history Commissioning The submarine's keel was laid at the Wilton-Fijenoord shipyard in Rotterdam on 15 June 1936 as ''K XIX'' but was renamed ''O 19'' at some point. The submarine was launched on 22 September 1938 and commissioned in the Dutch navy on 3 July 1939. After her commissioning the HNLMS ''O 19'' was put into service by commander Lieutenant-on-sea 1 (LTZ 1) K. van Dongen on July 3, 1939, following a short training period. Three weeks later, on 25 July 1939, the new submarine was already on its way to the Dutch East Indies via the Suez Canal where the boat arrived on 13 September.

Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now constitute the ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
U-boat
U-boats were naval submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most effectively used in an economic warfare role (commerce raiding) and enforcing a naval blockade against enemy shipping. The primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from Canada and other parts of the British Empire, and from the United States, to the United Kingdom and (during the Second World War) to the Soviet Union and the Allied territories in the Mediterranean. German submarines also destroyed Brazilian merchant ships during World War II, causing Brazil to declare war on both Germany and Italy on 22 August 1942. The term is an anglicised version of the German word ''U-Boot'' , a shortening of ''Unterseeboot'' ('under-sea-boat'), though the German term refers to any submarine. Austro-Hungarian Navy submarines were also kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gruppenhorchgerät
The ''Gruppenhorchgerät'' ('group listening device', abbreviated GHG) was a hydrophone array which was used on Nazi Germany's U-boats in World War II. Development In World War I carbon microphones were still used as sound receivers. The individual receivers were mostly placed in the front part of the vessel along the hull sides to have enough distance from the screw and the noise they emitted. The individual microphones were arranged in groups and each was oriented in a different direction. The individual microphones had to be connected manually to take bearings. They were not very reliable, so other transducers were experimented with. Dynamic microphones were also discarded. At the end of the process, the piezoelectric principle was deemed the most suitable. This was discovered by Pierre Curie in 1880. The quartz crystals generate electric voltage depending on the pressure acting on it. In collaboration with the Imperial German Navy, Atlas Werke AG in Bremen and ''Electroacust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bofors 40 Mm Automatic Gun L/60
The Bofors 40 mm Automatic Gun L/60 (often referred to simply as the "Bofors 40 mm gun", the "Bofors gun" and the like, see name) is an anti-aircraft autocannon, designed in the 1930s by the Swedish arms manufacturer AB Bofors. The gun was designed as an intermediate anti-aircraft gun, filling the gap between fast firing close-range small calibre anti-aircraft guns and slower firing long-range high calibre anti-aircraft guns, a role which previously was filled by older outdated guns. The Bofors 40 mm L/60 was for its time perfectly suited for this role and outperformed competing designs in the years leading up to World War II in both effectiveness and reliability. It entered the export market around 1932 and was in service with 18 countries by 1939. Throughout World War II it became one of the most popular and widespread medium-weight anti-aircraft guns. It was used by the majority of the western Allies and some Axis powers such as Nazi Germany and Hungary. In the pos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
