Duquesne-class Cruiser
The ''Duquesne''-class cruiser was a group of two heavy cruisers built for the French Navy in the mid 1920s, the first such vessels built for the French fleet. The two ships in the class were the and . With the ratification of the Washington Naval Treaty of 1922, France could not ignore the ramifications of the cruiser article. To maintain her position of a major naval power she would have to follow the other four major naval powers with her own 10,000-ton, 8-inch gun cruiser. The only modern cruiser design the ''Service techniques des constructions navales'' (STNC - Constructor's Department) had to draw on was the recently designed 8,000-ton design. The cruiser design authorized under the 1924 build program would sacrifice protection for speed while maintaining the 10,000-ton displacement restriction while mounting 8 inch guns. Two vessels would be authorized and would be known as the ''Duquesne''-class cruiser. Initially classed as a light cruiser, both ships were reclassi ...

Heavy Cruiser
A heavy cruiser was a type of cruiser, a naval warship designed for long range and high speed, armed generally with naval guns of roughly 203 mm (8 inches) in calibre, whose design parameters were dictated by the Washington Naval Treaty of 1922 and the London Naval Treaty of 1930. Heavy cruisers were generally larger, more heavily armed and more heavily armoured than light cruisers while being smaller, faster, and more lightly armed and armoured than battlecruisers and battleships. Heavy cruisers were not considered capital ships, unlike battlecruisers, battleships, and fleet carriers. Heavy cruisers were assigned a variety of roles ranging from commerce raiding to serving as 'cruiser-killers,' i.e. hunting and destroying similarly sized ships. The heavy cruiser is part of a lineage of ship design from 1915 through the early 1950s, although the term "heavy cruiser" only came into formal use in 1930. The heavy cruiser's immediate precursors were the light cruiser design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Indochina
French Indochina (previously spelled as French Indo-China), officially known as the Indochinese Union and after 1941 as the Indochinese Federation, was a group of French dependent territories in Southeast Asia from 1887 to 1954. It was initially a federation of French colonial empire, French colonies (1887–1949), later a confederation of French associated states (1949–1954). It comprised French protectorate of Cambodia, Cambodia, French protectorate of Laos, Laos (from 1899), Guangzhouwan (1898–1945), French Cochinchina, Cochinchina, and Nguyễn dynasty, Vietnamese regions of Tonkin (French protectorate), Tonkin and Annam (French protectorate), Annam. It was established in 1887 and was dissolved in 1954. In 1949, Vietnam was reunited and it regained Cochinchina. Its capitals were Hanoi (1902–1945) and Saigon (1887–1902, 1945–1954). The Second French Empire Cochinchina campaign, colonized Cochinchina in 1862 and established a French protectorate of Cambodia, protect ...

Invasion Of Normandy
Operation Overlord was the codename for the Battle of Normandy, the Allied operation that launched the successful liberation of German-occupied Western Europe during World War II. The operation was launched on 6 June 1944 ( D-Day) with the Normandy landings (Operation Neptune). A 1,200-plane airborne assault preceded an amphibious assault involving more than 5,000 vessels. Nearly 160,000 troops crossed the English Channel on 6 June, and more than two million Allied troops were in France by the end of August. The decision to undertake cross-channel landings in 1944 was made at the Trident Conference in Washington in May 1943. American General Dwight D. Eisenhower was appointed commander of Supreme Headquarters Allied Expeditionary Force, and British General Bernard Montgomery was named commander of the 21st Army Group, which comprised all the land forces involved in the operation. The Normandy coast in northwestern France was chosen as the site of the landings, with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mediterranean Sea
The Mediterranean Sea ( ) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern Europe, on the south by North Africa, and on the west almost by the Morocco–Spain border. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccation, desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The sea was an important ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Cruiser Tourville (1926)
''Tourville'' was the second ship of the cruisers of the French Navy. During the interwar period she served in the Mediterranean while taking periodic cruises to show the Flag. During the war she was on blockade duty in the mid Atlantic then the Mediterranean. She was interned for three years at Alexandria, rejoining the war effort in 1943. Again assigned to blockade duty in the Mid Atlantic at Dakar. Post war she aided in the restoration of French Colonial rule in French Indochina until placed in reserve in 1947. She remained in reserve until condemned for disposal in 1962. She was named to honour Anne-Hilarion de Costentien, comte de Tourville (1642 – 1701) who served with distinction under King Louis XIV. He fought against the British and Dutch at the battles of Beachy Head (French: Beveziers) and Barfluer. On 27 June 1693 defeated an English convoy commanded by George Rooke at Cape St Vincent and made Marshall of France. Design and description Under the 1924 progra ...

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 ...

Ship Floodability
Floodability is the susceptibility of a ship's construction to flooding. It also refers to the ability to intentionally flood certain areas of the hull for damage control purposes, or to increase stability, which is particularly important in combat vessels, which often face the possibility of serious hull breach due to enemy action, and which rely on well-trained damage controlmen to equalize and then stop flooding of the hull. Floodability is reduced by dividing the volume of the hull into watertight compartments with decks and bulkheads (which also increase the strength of ships), use of double bottom (or double hull), and by other means. If a ship's hull is divided into watertight compartments, any flooding resulting from a breach of the hull can be contained in the compartments where the flooding occurs. In most cases, the watertight compartments are fitted with a system of automatic doors, which can be triggered either remotely or locally as soon as flooding is detec ...

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] |
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 ...
