French Destroyer Sakalave
The French destroyer ''Sakalave'' was one of a dozen s built for the French Navy in Japan during the First World War. Design and description The ''Arabe''-class ships had an overall length of , a length between perpendiculars of , a beam of , and a draft of . The ships displaced at normal load. They were powered by three vertical triple-expansion steam engines, each driving one propeller shaft using steam provided by four mixed-firing Kampon Yarrow-type boilers. The engines were designed to produce , which would propel the ships at . During their sea trials, the ''Arabe'' class reached . The ships carried enough coal and fuel oil which gave them a range of at .Couhat, p. 118 Their crew consisted of 5 officers and 104 crewmen. The main armament of the ''Arabe''-class ships was a single Type 41 gun, mounted before the bridge on the forecastle. Their secondary armament consisted of four Type 41 guns in single mounts; two of these were positioned abreast the middle funnel an ...

Le Havre
Le Havre is a major port city in the Seine-Maritime department in the Normandy (administrative region), Normandy region of northern France. It is situated on the right bank of the estuary of the Seine, river Seine on the English Channel, Channel southwest of the Pays de Caux, very close to the Prime Meridian (Greenwich), Prime Meridian. Le Havre is the most populous commune of Upper Normandy, although the total population of the greater Le Havre conurbation is smaller than that of Rouen. It is also the second largest subprefecture in France, after only Reims. The name ''Le Havre'' means "the harbour" or "the port". Its inhabitants are known as ''Havrais'' or ''Havraises''. The city and Port of Le Havre, port were founded by Francis I of France, King Francis I in 1517. Economic development in the early modern period was hampered by European wars of religion, religious wars, conflicts with the English, epidemics, and storms. It was from the end of the 18th century that Le Havre st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Action Of 9 January 1921
The action of 9 January 1921 was a short naval battle fought during the Russian Civil War by the French Navy and the Soviet Russia. Background During the Russian Civil War, the French Navy was engaged as part of the Allied intervention provided assistance to the White movement engaged into the Southern Front. The French Navy suffered a mutiny in 1919 but operations were carried until the end of the conflict. Action The action involved the French s and , and also the ''Toul'', intercepting on sea the Soviet gunboat ''KL No. 7'' (ex-''Elpidifor No. 415''), which had completed mine-laying operation at Ak-Mechet and was carrying two motor torpedo boats built by Thornycroft. After a short gunfire battle, the Soviet ship was hit, grounded and lost with twelve killed and many wounded close Anapa Anapa (, , ) is a types of inhabited localities in Russia, town in Krasnodar Krai, Russia, located on the northern coast of the Black Sea near the Sea of Azov.

Russian Civil War
The Russian Civil War () was a multi-party civil war in the former Russian Empire sparked by the 1917 overthrowing of the Russian Provisional Government in the October Revolution, as many factions vied to determine Russia's political future. It resulted in the formation of the Russian Soviet Federative Socialist Republic, Russian Socialist Federative Soviet Republic and later the Soviet Union in most of its territory. Its finale marked the end of the Russian Revolution, which was one of the key events of the 20th century. The List of Russian monarchs, Russian monarchy ended with the abdication of Nicholas II, Tsar Nicholas II during the February Revolution, and Russia was in a state of political flux. A tense summer culminated in the October Revolution, where the Bolsheviks overthrew the Russian Provisional Government, provisional government of the new Russian Republic. Bolshevik seizure of power was not universally accepted, and the country descended into a conflict which beca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceremonial Ship Launching
Ceremonial ship launching involves the performing of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back millennia, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and in addition to the size and weight of the vessel represents a considerable engineering challenge as well as a public spectacle. The process also involves Sailors' superstitions, many traditions intended to invite good luck, such as baptism#Boats and ships, christening by breaking a sacrificial bottle of champagne over the bow (ship), bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The ol ...

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon designed to destroy submarine A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or infor ...s by detonating in the water near the target and subjecting it to a destructive shock factor, hydraulic shock. Most depth charges use high explosives with a fuze set to detonate the charge, typically at a specific depth from the surface. Depth charges can be dropped by ships (typically fast, agile surface combatants such as destroyers or frigates), patrol aircraft and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, duri ...

Anti-aircraft Gun
Anti-aircraft warfare (AAW) is the counter to aerial warfare and includes "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It encompasses surface-based, subsurface ( submarine-launched), and air-based weapon systems, in addition to associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defense. Missile defense is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. Most modern anti-aircraft (AA) weapons systems are optimized for short-, medium-, or long-range air defence, although some systems may incorporate multiple weapons (such as both autocannons and surface-to-air missiles). 'Layered air defence' usually refers to multiple 'tiers' of air defence systems which, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Funnel (ship)
A funnel is the smokestack or chimney on a ship used to expel boiler steam and smoke or engine exhaust gas, exhaust. They are also commonly referred to as stacks. Purpose The primary purpose of a ship's funnel(s) is to lift the exhaust gases clear of the deck, in order not to foul the ship's structure or decks, and to avoid impairing the ability of the crew to carry out their duties. In steam ships the funnels also served to help induce a boiler draught, convection draught through the boilers. Design Since the introduction of steam-power to ships in the 19th century, the funnel has been a distinctive feature of the silhouette of a vessel, and used for recognition purposes. Funnel area The required funnel cross-sectional area is determined by the volume of exhaust gases produced by the propulsion plant. Often this area is too great for a single funnel. Early steam vessels needed multiple funnels ( had 5 when launched), but as efficiency increased new machinery needed fewe ...

Forecastle
The forecastle ( ; contracted as fo'c'sle or fo'c's'le) is the upper deck (ship), 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 "Wiktionary:before the mast, 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 (ship), 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 (sailing), 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 th ...

Bridge (nautical)
A bridge (also known as a command deck), or wheelhouse (also known as a pilothouse), is a room or platform of a ship, submarine, airship, or spacecraft, spaceship from which the ship can be commanded. When a ship is under way, the bridge is manned by an Watchstanding, officer of the watch aided usually by an Able Seaman (occupation), able seaman acting as a lookout. During critical maneuvers the Captain (naval), captain will be on the bridge, often supported by an officer of the watch, an able seaman on the wheel and sometimes a Maritime pilot, pilot, if required.

Fuel Oil
Fuel oil is any of various fractions obtained from the distillation of petroleum (crude oil). Such oils include distillates (the lighter fractions) and residues (the heavier fractions). Fuel oils include heavy fuel oil (bunker fuel), marine fuel oil (MFO), furnace oil (FO), gas oil (gasoil), heating oils (such as home heating oil), diesel fuel, and others. The term ''fuel oil'' generally includes any liquid fuel that is burned in a furnace or boiler to generate heat ( heating oils), or used in an engine to generate power (as motor fuels). However, it does not usually include other liquid oils, such as those with a flash point of approximately , or oils burned in cotton- or wool-wick burners. In a stricter sense, ''fuel oil'' refers only to the heaviest commercial fuels that crude oil can yield, that is, those fuels heavier than gasoline (petrol) and naphtha. Fuel oil consists of long-chain hydrocarbons, particularly alkanes, cycloalkanes, and aromatics. Small molecul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
