French Sloop Élan
''Élan'' was the lead ship of her class of 13 minesweeping sloops () built for the French Navy during the late 1930s. Completed in 1939, she was participated in the Second World War. The ship was interned in Turkey in June 1941 and released to the Free French Naval Forces in December 1944. She remained in service after the war and was decommissioned on 26 March 1958 and scrapped. Description The ''Élan'' class had a (standard displacement) of and displaced at deep load. The vessels were long overall and between perpendiculars with a beam of and a draught of at deep load. They were powered by two Sulzer diesel engines rated at a total of , each driving one propeller shaft which gave them a speed of . The ships carried enough fuel oil to give them a maximum range of at . They were fitted with an auxiliary rudder built into the bow. The ships had a complement of 88 in peacetime and 106 during wartime. The main battery of the ''Élan'' class was intended to consist o ...

Arsenal De Lorient
Naval Group is a major French industrial Corporate group, group specializing in navy, naval defense industry, defense design, development and shipbuilding, construction. Its headquarters are located in Paris. Heir to the French naval dockyards initiated in 1631 by Cardinal Richelieu and to the Direction des Constructions et Armes Navales (''DCAN''), which became Direction des Constructions Navales (''DCN'') in 1991 and then DCNS in 2007, the company was rebranded ''Naval Group'' in 2017. Its two main shareholders are the Agence des participations de l'État, French State (62.25%) and Thales Group (35%). In 2024, Naval Group employs 15,261 people across 17 countries. History Naval Group has a heritage of almost 400 years. Major shipyards were built in France in Brest (1631), Nantes-Indret (1771), Lorient (1778) and, subsequently, Cherbourg (1813). Others were to follow. As early as 1926, what we know as the Naval Group today already had all the facilities now owned by the group ...

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 ...

Depth Charge Rack
A depth charge is an anti-submarine warfare (ASW) weapon designed to destroy submarines by detonating in the water near the target and subjecting it to a destructive 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, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-subm ...

Broadside (naval)
A broadside is the side of a ship, or more specifically the artillery battery, battery of cannon on one side of a warship or their coordinated fire in naval warfare, or a measurement of a warship's maximum simultaneous firepower which can be delivered upon a single target (because this concentration is usually obtained by firing a broadside). From the 16th century until the early decades of the steamship, vessels had rows of guns set in each side of the hull (watercraft), hull. Firing all guns on one side of the ship became known as a "broadside". The cannon of 18th-century man-of-war, men of war were accurate only at short range, and their penetrating power mediocre, which meant that the thick hulls of wooden ships could only be pierced at short ranges. These wooden ships sailed closer and closer towards each other until cannon fire would be effective. Each tried to be the first to fire a broadside, often giving one party a decisive headstart in the battle when it crippled the oth ...

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 ...

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.

Anti-aircraft Warfare
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#Armament, 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, army, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defense. Missile 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 't ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superstructure
A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of physical structures such as buildings, bridges, or ships. Aboard ships and large boats On water craft, the superstructure consists of the parts of the ship or a boat, including sailboats, fishing boats, passenger ships, and submarines, that project above her main deck. This does not usually include its Mast (sailing), masts or any armament gun turret, turrets. Note that, in modern times, turrets do not always carry naval artillery. They can also carry missile launchers and/or antisubmarine warfare weapons. The size of a watercraft's superstructure can have many implications in the performance of ships and boats, since these structures can alter their structural rigidity, their displacements, and/or stability. These can be detrimental to any vessel's performance if they are taken into consideration incorrectly. The height and the weight of superstructure ...

Main Battery
A main battery is the primary weapon or group of weapons around which a warship is designed. As such, a main battery was historically a naval gun or group of guns used in volleys, as in the broadsides of cannon on a ship of the line. Later, this came to be turreted groups of similar large-caliber naval rifles. With the evolution of technology the term has come to encompass guided missiles and torpedoes as a warship's principal offensive weaponry, deployed both on surface ships and submarines. A main battery features common parts, munition and fire control system across the weapons which it comprises. Description In the age of cannon at sea, the main battery was the principal group of weapons around which a ship was designed, usually its heavies. With the coming of naval rifles and subsequent revolving gun turrets, the main battery became the principal group of heaviest guns, regardless of how many turrets they were placed in. As missiles displaced guns both above and belo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship's Company
A ship's company or complement comprises all officers, non-commissioned officers and enlisted personnel aboard a naval vessel, excluding civilians and guests. United States Aircraft-capable ships An exception to this rule is the definition of ship's company as it applies to the U.S. Navy and U.S. Marine Corps personnel assigned to aircraft-capable ships of the U.S. Navy, primarily aircraft carriers and amphibious assault ships. In the case of aircraft carriers in the U.S. Navy, the total ship's complement is divided into three categories: # the ship's company physically assigned to the ship, and # the carrier air wing, with its associated strike fighter, U.S. Marine fighter/attack, electronic attack, airborne early warning and helicopter squadrons, and a detachment of a fleet logistics squadron, which is considered a separate "embarked" command, and # the carrier strike group commander and staff, which is also considered an "embarked" command The number of personnel assigned ...

Bow (ship)
The bow () is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline. Function A ship's bow should be designed to enable the hull to pass efficiently through the water. Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function. Where sea conditions are likely to promote pitching, it is useful if the bow provides reserve buoyancy; a flared bow (a raked stem with flared topsides) is ideal to reduce the amount of water shipped over the bow. Ideally, the bow should reduce the resistance and should be tall enough to prevent water from regularly washing over the top of it. Large commercial barges on inland waterways rarely meet big waves and may have remarkably little freeboard at the bow, whereas fast military ...

Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, airship, or other vehicle that moves through a fluid medium (usually air or water). On an airplane, the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull or fuselage, thus imparting a turning or yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or afterend. Often rudders are shaped to minimize hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical linkages or hydraulics. H ...
