Floréal-class Frigate
The ''Floréal'' class is a type of light "surveillance frigates" () designed for the needs of the French Navy in low-threat environments ordered in 1989. The ships are named after months of the French Republican Calendar, Republican Calendar. They use construction standards of commercial ships. The frigates were built between 1990 and 1993 by the Chantiers de l'Atlantique at Saint-Nazaire, France. The six French ships of the class, , , , , and , remain in active service. The ships' main armament was two Exocet MM38 surface-to-surface missiles and a French 100 mm naval gun, CADAM turret, but in 2014, the Exocets were removed at the end of their life cycle. The vessels have a maximum speed of and can carry 24 marines. The vessels are used mainly to patrol the Overseas department and region, French overseas departments and regions in the Pacific, Indian Ocean and Caribbean Sea, Caribbean regions, but have served in both military and humanitarian operations in the Persian Gulf and ...

Chantiers De L'Atlantique
Chantiers de l'Atlantique is a shipyard in Saint-Nazaire, Saint-Nazaire, France. It is one of the world's largest shipyards, constructing a wide range of commercial, naval, and passenger ships. It is located near Nantes, at the mouth of the Loire, Loire river and the deep waters of the Atlantic Ocean, Atlantic, which make the sailing of large ships in and out of the shipyards easy. The shipyard was owned by Alstom from 1976 onwards, became Alstom-Atlantique, and was later part of Aker Yards when Aker ASA, Aker Group acquired the Alstom Marine business in 2006. In 2008, the South Korean company STX Corporation acquired Aker Yards, and the shipyard became part of STX Europe (formed by the renaming of Aker Yards). After the bankruptcy of STX Corporation, the shipyard was acquired by the French government and reverted to its original name of Chantiers de l'Atlantique. History The current Chantiers de l'Atlantique yard evolved from the Ateliers et Chantiers de Saint-Nazaire Penhoët, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface-to-surface Missile
A surface-to-surface missile (SSM) is a missile designed to be launched from the ground or the sea and strike targets on land or at sea. They may be fired from hand-held or vehicle mounted devices, from fixed installations, or from a ship. They are often powered by a rocket engine or sometimes fired by an explosive charge, since the launching platform is typically stationary or moving slowly. They usually have fins and/or wings for lift and stability, although hyper-velocity or short-ranged missiles may use body lift or fly a ballistic trajectory. The first operational surface-to-surface missile was the V-1 flying bomb, it was powered by a pulsejet engine. Contemporary surface-to-surface missiles are usually guided. An unguided surface-to-surface missile is usually referred to as a rocket (for example, an RPG-7 or M72 LAW is an anti-tank rocket), whereas a BGM-71 TOW or AT-2 Swatter is an anti-tank guided missile. Examples of surface-to-surface missile include the MGM-140 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Bulkhead (partition)
A bulkhead is an upright wall within the hull (watercraft), hull of a ship, within the fuselage of an airplane, or a car. Other kinds of partition elements within a ship are deck (ship), decks and deckheads. Etymology The word ''bulki'' meant "cargo" in Old Norse. During the 15th century sailors and builders in Europe realized that walls within a vessel would prevent cargo from shifting during passage. In shipbuilding, any vertical panel was called a head. So walls installed abeam (side-to-side) in a vessel's hull were called "bulkheads". Now, the term bulkhead applies to every vertical panel aboard a ship, except for the hull itself. History Bulkheads were known to the ancient Greeks, who employed bulkheads in triremes to support the back of rams. By the Athenian trireme era (500 BC), the hull was strengthened by enclosing the bow behind the ram, forming a bulkhead compartment. Instead of using bulkheads to protect ships against rams, Greeks preferred to reinforce the hull ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...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 ...

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 ...

Exclusive Economic Zone
An exclusive economic zone (EEZ), as prescribed by the 1982 United Nations Convention on the Law of the Sea, is an area of the sea in which a sovereign state has exclusive rights regarding the exploration and use of marine natural resource, resources, including energy production from water and wind. It stretches from the outer limit of the territorial sea (22.224 kilometres or 12 nautical miles from the baseline) out 370.4 kilometres (or 200 nautical miles) from the coast of the state in question. It is also referred to as a maritime continental margin and, in colloquial usage, may include the continental shelf. The term does not include either the Territorial waters#Territorial sea, territorial sea or the continental shelf beyond the 200 nautical mile limit. The difference between the territorial sea and the exclusive economic zone is that the first confers full sovereignty over the waters, whereas the second is merely a "sovereign right" which refers to the coastal state's righ ...

Gulf Of Guinea
The Gulf of Guinea (French language, French: ''Golfe de Guinée''; Spanish language, Spanish: ''Golfo de Guinea''; Portuguese language, Portuguese: ''Golfo da Guiné'') is the northeasternmost part of the tropical Atlantic Ocean from Cape Lopez in Gabon, north and west to Cape Palmas in Liberia. Null Island, defined as the intersection of the Equator and Prime Meridian (zero degrees latitude and longitude), is in the gulf. Among the many rivers that drain into the Gulf of Guinea are the Niger River, Niger and the Volta River, Volta. The coastline on the gulf includes the Bight of Benin and the Bight of Bonny. Name "Guinea" is thought to have originated from a local name for an area in the region, although the specifics are disputed. Bovill (1995) gives a thorough description: The name "Guinea (region), Guinea" was also previously applied to the south coast of West Africa (north of the Gulf of Guinea), which became known as "Upper Guinea", and to the west coast of Southern Afri ...
