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] |
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 ...

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] |
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 ...

Çanakkale
Çanakkale (pronounced ), ancient ''Dardanellia'' (), is a city and seaport in Turkey in Çanakkale province on the southern shore of the Dardanelles at their narrowest point. The population of the city is 195,439 (2021 estimate). Çanakkale is the nearest major urban centre to the ancient city of Troy, which (together with the ancient region of the Troad) is also located inside Çanakkale Province. The wooden horse from the 2004 movie ''Troy'' is exhibited on the Çanakkale waterfront. Today Çanakkale is the main base for visits to the ruins of Troy and to the First World War cemeteries at Gallipoli. Particularly around 18 March and 25 April (ANZAC Day) when there are major celebrations of the two different interpretations of the events of the war the town fills with visitors and every hotel room is likely to be booked up for months in advance. Every year Çanakkale is the finishing point for a demanding swim across the Dardanelles from Eceabat. This event reproduces the sw ...

HMS Penshurst
HMS ''Penshurst'' was a Royal Navy warship that was active during World War I. She was a Special Service Vessel (also known as Q-ships) whose function was to act as a decoy, inviting attack by a U-boat in order to engage and (if possible) destroy it. ''Penshurst'' fought a number of engagements against German U-boats during her service, and was successful on two occasions, destroying in November 1916, and in January 1917. ''Penshurst'' was sunk following an action with in December 1917. Early career ''Penshurst'' was built in 1906 as a cargo steamer, and had an uneventful peacetime career before the start of World War I. In 1915 she was requisitioned by the Royal Navy for conversion into a special service vessel. She was taken in hand at Longhope, part of the Scapa Flow naval base in the Orkney Islands. She was armed with five guns originally; this was increased later in the campaign. These were a 12-pounder, two 6-pounder and two 3-pounder guns, hidden behind screens and dum ...

Q-ship
Q-ships, also known as Q-boats, decoy vessels, special service ships, or mystery ships, were heavily armed merchant ships with concealed weaponry, designed to lure submarines into making surface attacks. This gave Q-ships the chance to open fire and sink them. The use of Q-ships contributed to the abandonment of cruiser rules restricting attacks on unarmed merchant ships and to the shift to unrestricted submarine warfare in the 20th century. They were used by the British Royal Navy and the German ''Kaiserliche Marine'' during the First World War and by the Royal Navy, the '' Kriegsmarine'', and the United States Navy during the Second World War (1939–45). Etymology Short for Queenstown in Ireland, as Haulbowline Dockyard in Cork Harbour was responsible for the conversion of many mercantile steamers to armed decoy ships in World War One, although the majority appear to have been converted in larger navy yards such as Devonport.

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called naval mine, mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with naval artillery, large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface combatant , surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large shi ...

German Imperial Navy
The Imperial German Navy or the Imperial Navy () was the navy of the German Empire, which existed between 1871 and 1919. It grew out of the small Prussian Navy (from 1867 the North German Federal Navy), which was mainly for coast defence. Kaiser Wilhelm II greatly expanded the navy. The key leader was Admiral Alfred von Tirpitz, who greatly expanded the size and quality of the navy, while adopting the sea power theories of American strategist Alfred Thayer Mahan. The result was a naval arms race with Britain, as the German navy grew to become one of the greatest maritime forces in the world, second only to the Royal Navy. The German surface navy proved ineffective during the First World War; its only major engagement, the Battle of Jutland, was a draw, but it kept the surface fleet largely in port for the rest of the war. The submarine fleet was greatly expanded and threatened the British supply system during the U-boat campaign. As part of the Armistice, the Imperial Navy's mai ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
