B97-class Torpedo Boat
The ''B 97'' class was a class of eight destroyers built for and operated by the Imperial German Navy (''Kaiserliche Marine'') during the First World War. They served throughout the war, with one being lost in 1915, five being scuttled at Scapa Flow in 1919 and one being transferred to Italy, where it remained in use until 1939. Design As part of its 1912 construction programme, the Imperial Russian Navy placed orders for 22 large modern destroyers (the ) for its Baltic Fleet. In order to speed delivery of these ships, orders for the ship's machinery were placed overseas, including in Germany. The outbreak of the First World War, with Germany declaring war on Russia on 1 August, led to delivery of these machinery sets to be stopped. The AG Vulcan shipyard in Stettin, (now Szczecin in Poland) proposed to use this machinery to power a class of large destroyers for the Imperial German Navy, which could be built within six months. The German navy was at first unenthusiastic about Vulc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
G101-class Torpedo Boat
The ''G101'' class was a class of four large torpedo boats (sometimes rated as destroyers) that were ordered for the Argentine Navy from the German shipyard Germaniawerft in 1912. They were still building on the outbreak of the First World War in August 1914 when they were seized on behalf of the Kaiserliche Marine (Imperial German Navy). All four ships completed in 1915 and serving through the rest of the war, with three ships present at the Battle of Jutland in 1916. Three ships were scuttled at Scapa Flow in 1919 and one sunk as a target by American aircraft in 1921. Design In 1910, the Argentine Navy placed orders for twelve large destroyers with the orders split between the British shipyard Cammell Laird (four ships), the French shipyard Ateliers et Chantiers de Bretagne (four ships) and the German shipyards Germaniawerft and Schichau-Werke (two each). The four German-built ships were completed in 1912 and delivered that year, but the four British-built ships were purch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draft (ship)
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] |

Operation Albion
Operation Albion was a World War I German air, land and naval operation against the Russian forces in October 1917 to occupy the West Estonian Archipelago. The land campaign opened with German landings at the Tagalaht bay on the island of Saaremaa, on 12 October 1917, after extensive naval operations to clear mines and subdue coastal artillery batteries. The Germans secured the island by 16 October and the Russian army evacuated Muhu on 20 October. After two failed attempts, the Germans landed on Hiiumaa on 12 October, capturing the island on the following day. The Russian Baltic Fleet had to withdraw from the Suur Strait after its losses at the Battle of Moon Sound. The Germans claimed 20,000 prisoners and 100 guns captured during Operation Albion from 12 to 20 October. Strategic significance At the beginning of World War I the islands were of little importance to the Russian Empire or Germany. After the revolutionary turmoil in Russia during the early part of 1917, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Jutland
The Battle of Jutland (german: Skagerrakschlacht, the Battle of the Skagerrak) was a naval battle fought between Britain's Royal Navy Grand Fleet, under Admiral John Jellicoe, 1st Earl Jellicoe, Sir John Jellicoe, and the Imperial German Navy's High Seas Fleet, under Vice-Admiral Reinhard Scheer, during the First World War. The battle unfolded in extensive manoeuvring and three main engagements (the battlecruiser action, the fleet action and the night action), from 31 May to 1 June 1916, off the North Sea coast of Denmark's Jutland Peninsula. It was the largest naval battle and the only full-scale clash of battleships in that war. Jutland was the third fleet action between steel battleships, following the Battle of the Yellow Sea in 1904 and the Battle of Tsushima in 1905, during the Russo-Japanese War. Jutland was the last major battle in history fought primarily by battleships. Germany's High Seas Fleet intended to lure out, trap, and destroy a portion of the British Grand ...

Battle Of The Gulf Of Riga
The Battle of the Gulf of Riga was a World War I naval operation of the German High Seas Fleet against the Russian Baltic Fleet in the Gulf of Riga in the Baltic Sea in August 1915. The operation's objective was to destroy the Russian naval forces in the Gulf in preparation for landing German troops to facilitate the fall of Riga in the later stages of the Central Powers' offensive on the Eastern Front in 1915. The German fleet, however, failed to achieve its objective and was forced to return to its bases; Riga remained in Russian hands until it fell to the German Army on 1 September 1917. Prelude In early August 1915, several powerful units of the German High Seas Fleet were transferred to the Baltic to participate in the foray into the Riga Gulf. The intention was to destroy the Russian naval forces in the area, including the pre-dreadnought battleship , and to use the minelayer to block the entrance to Moon Sound with mines. The German naval forces, under the command of Vice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

North Sea
The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium. An epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, covering . It hosts key north European shipping lanes and is a major fishery. The coast is a popular destination for recreation and tourism in bordering countries, and a rich source of energy resources, including wind and wave power. The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Vikings' rise. The Hanseatic League, the Dutch Republic, and the British each sought to gain command of the North Sea and access t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baltic Sea
The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden and the North and Central European Plain. The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. A marginal sea of the Atlantic, with limited water exchange between the two water bodies, the Baltic Sea drains through the Danish Straits into the Kattegat by way of the Øresund, Great Belt and Little Belt. It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga and the Bay of Gdańsk. The " Baltic Proper" is bordered on its northern edge, at latitude 60°N, by Åland and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the west by the Swedish part of the southern Scandinavian Peninsula. The Baltic Sea is connected by artificial waterways to the White Sea via the White Sea–Baltic Canal and to the German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forecastle
The forecastle ( ; contracted as fo'c'sle or fo'c's'le) is the upper deck of a sailing ship forward of the foremast, or, historically, the forward part of a ship with the sailors' living quarters. Related to the latter meaning is the phrase " before the mast" which denotes anything related to ordinary sailors, as opposed to a ship's officers. History and design In medieval shipbuilding, a ship of war was usually equipped with a tall, multi-deck castle-like structure in the bow of the ship. It served as a platform for archers to shoot down on enemy ships, or as a defensive stronghold if the ship were boarded. A similar but usually much larger structure, called the aftcastle, was at the aft end of the ship, often stretching all the way from the main mast to the stern. Having such tall upper works on the ship was detrimental to sailing performance. As cannons were introduced and gunfire replaced boarding as the primary means of naval combat during the 16th century, the medieval ...

High Explosive
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caliber (artillery)
In artillery, caliber or calibredifference in British English and American English spelling is the internal diameter of a gun barrel, or - by extension - a relative measure of the barrel length. Rifled barrels Rifled barrels introduce ambiguity to measurement of caliber. A rifled bore consists of alternating grooves and lands. The distance across the bore from groove to groove is greater than the distance from land to land. Projectiles fired from rifled barrels must be of the full groove to groove diameter to be effectively rotated by the rifling, but the caliber has sometimes been specified as the land to land diameter before rifling grooves were cut. The depth of rifling grooves (and the consequent ambiguity) increases in larger calibers. Steel artillery projectiles may have a forward bourrelet section machined to a diameter slightly smaller than the original land to land dimension of the barrel and a copper driving band somewhat larger than the groove to groove diameter t ...
