SMS München
SMS ('His Majesty's Ship ') was the fifth of seven s of the Imperial German Navy, named after the city of Munich. She was built by AG Weser in Bremen, starting in 1903, launched in April 1904, and commissioned in January 1905. Armed with a main battery of ten guns and two torpedo tubes, was capable of a top speed of . served with the fleet for the majority of her career, and saw extensive service during World War I, including at the Battle of Jutland on 31 May – 1 June 1916. There, she engaged British light cruisers on two instances, and was damaged in both; she contributed to the damaging of the cruiser during the latter engagement. was torpedoed by the British submarine on 19 October 1916, and was subsequently withdrawn from service. She spent the final year of the war as a barracks ship, and was surrendered as a war prize to the British in 1920. was later sunk as a torpedo target. Design The German 1898 Naval Law called for the replacement of the fleet's ol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World War I
World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a World war, global conflict between two coalitions: the Allies of World War I, Allies (or Entente) and the Central Powers. Fighting took place mainly in European theatre of World War I, Europe and the Middle Eastern theatre of World War I, Middle East, as well as in parts of African theatre of World War I, Africa and the Asian and Pacific theatre of World War I, Asia-Pacific, and in Europe was characterised by trench warfare; the widespread use of Artillery of World War I, artillery, machine guns, and Chemical weapons in World War I, chemical weapons (gas); and the introductions of Tanks in World War I, tanks and Aviation in World War I, aircraft.

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p. 5. This is accomplished by means of its "draft marks". A merchant vessel has t ...

Draft (hull)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if de ...

Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cora ...

Length Overall
Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often reported. T ...

Hull (watercraft)
A hull is the watertight body of a ship, boat, submarine, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or Mast (sailing), mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box, in the case of scow barges, to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bot ...

German Colonial Empire
The German colonial empire () constituted the overseas colonies, dependencies, and territories of the German Empire. Unified in 1871, the chancellor of this time period was Otto von Bismarck. Short-lived attempts at colonization by Kleinstaaterei, individual German states had occurred in preceding centuries, but Bismarck resisted pressure to construct a colonial empire until the Scramble for Africa in 1884. Claiming much of the remaining uncolonized areas of Africa, Germany built the third-largest colonial empire at the time, after the British Empire, British and Second French colonial empire, French. The German colonial empire encompassed parts of Africa and Oceania. Germany lost control of most of its colonial empire at the beginning of the World War I, First World War in 1914, but some German forces held out in German East Africa until the end of the war. After the Armistice of 11 November 1918, German defeat in World , Germany's colonial empire was officially confiscated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aviso
An ''aviso'' was originally a kind of dispatch boat or "advice boat", carrying orders before the development of effective remote communication. The term, derived from the Portuguese and Spanish word for "advice", "notice" or "warning", an ''aviso'', was later adopted by the French and Portuguese navies to classify their medium-sized warships designed for colonial service. The term continued to be used in the French Navy to classify the patrol frigates until 2012, when the remaining ships of the class were reclassified as offshore patrol ships. It is equivalent to the modern use of " sloop" in other countries. Description The ''Dictionnaire de la Marine Française 1788–1792'' (by Nicolas-Charles Romme) describes ''avisos'' as "small boats designed to carry orders or dispatches". By the late 19th century, an aviso could be of several hundred tons displacement. Usually very lightly armed and often not significantly faster than battleships or cruisers, the aviso was no ...

Unprotected Cruiser
An unprotected cruiser was a type of naval warship that was in use during the early 1870s Victorian era, Victorian or Pre-dreadnought battleship, pre-dreadnought era (about 1880 to 1905). The name was meant to distinguish these ships from “protected cruisers”, which had become accepted in the 1880s. A protected cruiser did not have side armor on its hull like a battleship or “armored cruiser” but had only a curved armored deck built inside the ship — like an internal turtle shell — which prevented enemy fire penetrating through the ship down into the most critical areas such as machinery, boilers, and ammunition storage. An unprotected cruiser lacked even this level of internal protection. The definitions had some gray areas, because individual ships could be built with a protective deck that did not cover more than a small area of the ship, or was so thin as to be of little value. The same was true of the side armor on some armored cruisers. An unprotected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Corvette
Steam frigates (including screw frigates) and the smaller steam corvettes, steam sloops, steam gunboats and steam schooners, were steam-powered warships that were not meant to stand in the line of battle. The first such ships were paddle steamers. Later on the invention of screw propulsion enabled construction of screw-powered versions of the traditional frigates, corvettes, sloops and gunboats. Evolution First steam warships The first small vessel that can be considered a steam warship was the '' Demologos'', which was launched in 1815 for the United States Navy. From the early 1820s, the British Navy began building a number of small steam warships including the armed tugs and , and by the 1830s the navies of America, Russia and France were experimenting with steam-powered warships. Hellenic sloop-of-war '' Kartería'' (Καρτερία; Greek for "Perseverance") was the first steam-powered warship to be used in combat operations in history. It was built in 1825 in an Eng ...
