HMS Seneschal (P255)
HMS ''Seneschal'' was a British S-class submarine (1931), S-class submarine of the third batch built for the Royal Navy during World War II. She survived the war and was sold for scrap in 1965. Design and description The last 17 boats of the third batch were significantly modified from the earlier boats. They had a stronger hull, carried more fuel and their armament was revised. The submarines had a length of length overall, overall, a beam (nautical), beam of and a draft (ship), draft of . They displacement (ship), displaced on the surface and submerged.Chesneau, p. 52 The S-class submarines had a crew of 48 officers and naval rating, ratings. They had a diving depth of .McCartney, p. 7 For surface running, the boats were powered by two diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a electric motor. They could reach on the surface and underwater. On the surface, the third batch boats had a range of at and at submerge ...

Naval Ensign Of The United Kingdom
The White Ensign, at one time called the St George's Ensign due to the simultaneous existence of a cross-less version of the flag, is an ensign worn on British Royal Navy ships and shore establishments. It consists of a red St George's Cross on a white field, identical to the flag of England except with the Union Flag in the upper canton. The White Ensign is also worn by yachts of members of the Royal Yacht Squadron and by ships of Trinity House escorting the reigning monarch. In addition to the United Kingdom, several other nations have variants of the White Ensign with their own national flags in the canton, with the St George's Cross sometimes being replaced by a naval badge omitting the cross altogether. Yachts of the Royal Irish Yacht Club wear a white ensign with an Irish tricolour in the first quadrant and defaced by the crowned harp from the Heraldic Badge of Ireland.

Draft (ship)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull ( keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fleet Review
A fleet review or naval review is an event where a gathering of ships from a particular navy is paraded and reviewed by an incumbent head of state and/or other official civilian and military dignitaries. A number of national navies continue to hold fleet reviews. Fleet reviews may also include participants and warships from multiple navies. Commonwealth realms Fleet reviews in the Commonwealth realms are typically observed by the reigning monarch or their representative, a practice allegedly dating back to the 15th century. Such an event is not held at regular intervals and originally only occurred when the fleet was mobilised for war or for a show of strength to discourage potential enemies, or during periods of commemorations. Since the 19th century, they have often been held for the coronation or for special royal jubilees and increasingly included delegates from other national navies. Traditionally, a fleet review will have participating ships dressed in flags and pennants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the World War II by country, vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies of World War II, Allies and the Axis powers. World War II was a total war that directly involved more than 100 million Military personnel, personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Air warfare of World War II, Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the Atomic bombings of Hiroshima and Nagasaki, only two nuclear weapons ever used in war.

Seneschal
The word ''seneschal'' () can have several different meanings, all of which reflect certain types of supervising or administering in a historic context. Most commonly, a seneschal was a senior position filled by a court appointment within a royal, ducal, or noble household during the Middle Ages and early Modern period – historically a steward or majordomo of a medieval great house. In a medieval royal household, a seneschal was in charge of domestic arrangements and the administration of servants, which, in the medieval period particularly, meant the seneschal might oversee hundreds of laborers, servants and their associated responsibilities, and have a great deal of power in the community, at a time when much of the local economy was often based on the wealth and responsibilities of such a household. A second meaning is more specific, and concerns the late medieval and early modern nation of France, wherein the seneschal (french: sénéchal) was also a royal officer in cha ...

Naval Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individuals ...

British 21 Inch Torpedo
There have been several British 21-inch (533 mm) torpedoes used by the Royal Navy since their first development just before the First World War. Torpedoes of 21 inch calibre were the largest torpedoes in common use in the RN. They were used by surface ships and submarines rather than aircraft, which used smaller 18-inch torpedoes. Mark I The first British 21-inch torpedo came in two lengths, "Short" at , and "Long" at . The explosive charge was of gun cotton increased later to . Mark II The Mark II, chiefly used by destroyers, entered service in 1914. Apart from some older British ships, it was used with the old US ( destroyers-for-bases deal) Town-class destroyers provided to the UK during the early part of the Second World War. The running speed was reduced from (over 3,000 yards) for better reliability. The Mark II*, an improved Mark II, was used by battleships and battlecruisers. A wet heater design, it could run for at .

Propeller Shaft
A drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power and torque and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a splined joint or prismatic joint. History The term ''driveshaft'' first appeared during the mid-19th centu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
