Seatrial
A sea trial is the testing phase of a watercraft (including boats, ships, and submarines). It is also referred to as a "shakedown cruise" by many naval personnel. It is usually the last phase of construction and takes place on open water, and it can last from a few hours to many days. Sea trials are conducted to measure a vessel's performance and general seaworthiness. Testing of a vessel's speed, maneuverability, equipment and safety features are usually conducted. Usually in attendance are technical representatives from the builder (and from builders of major systems), governing and certification officials, and representatives of the owners. Successful sea trials subsequently lead to a vessel's certification for commissioning and acceptance by its owner. Although sea trials are commonly thought to be conducted only on new-built vessels (referred by shipbuilders as 'builders trials'), they are regularly conducted on commissioned vessels as well. In new vessels, they are us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cunard Line
Cunard () is a British shipping and cruise line based at Carnival House at Southampton, England, operated by Carnival UK and owned by Carnival Corporation & plc. Since 2011, Cunard and its three ships have been registered in Hamilton, Bermuda. In 1839, Samuel Cunard was awarded the first British transatlantic steamship mail contract, and the next year formed the British and North American Royal Mail Steam-Packet Company in Glasgow with shipowner Sir George Burns together with Robert Napier, the famous Scottish steamship engine designer and builder, to operate the line's four pioneer paddle steamers on the Liverpool–Halifax–Boston route. For most of the next 30 years, Cunard held the Blue Riband for the fastest Atlantic voyage. However, in the 1870s Cunard fell behind its rivals, the White Star Line and the Inman Line. To meet this competition, in 1879 the firm was reorganised as the Cunard Steamship Company, Ltd, to raise capital. In 1902, White Star joined the Ame ...

Luftwaffe
The ''Luftwaffe'' () was the aerial-warfare branch of the German ''Wehrmacht'' before and during World War II. Germany's military air arms during World War I, the ''Luftstreitkräfte'' of the Imperial Army and the '' Marine-Fliegerabteilung'' of the Imperial Navy, had been disbanded in May 1920 in accordance with the terms of the 1919 Treaty of Versailles which banned Germany from having any air force. During the interwar period, German pilots were trained secretly in violation of the treaty at Lipetsk Air Base in the Soviet Union. With the rise of the Nazi Party and the repudiation of the Versailles Treaty, the ''Luftwaffe''s existence was publicly acknowledged on 26 February 1935, just over two weeks before open defiance of the Versailles Treaty through German rearmament and conscription would be announced on 16 March. The Condor Legion, a ''Luftwaffe'' detachment sent to aid Nationalist forces in the Spanish Civil War, provided the force with a valuable testing grou ...

Harbour Pilot
A harbor (American English), harbour (British English; American and British English spelling differences#-our, -or, see spelling differences), or haven is a sheltered body of water where ships, boats, and barges can be docked. The term ''harbor'' is often used interchangeably with ''port'', which is a man-made facility built for loading and unloading Watercraft, vessels and dropping off and picking up passengers. Ports usually include one or more harbors. Alexandria Port in Egypt is an example of a port with two harbors. Harbors may be natural or artificial. An artificial harbor can have deliberately constructed breakwater (structure), breakwaters, sea walls, or jettys or they can be constructed by dredging, which requires maintenance by further periodic dredging. An example of an artificial harbor is Long Beach Harbor, California, United States, which was an array of salt marshes and tidal flats too shallow for modern merchant ships before it was first dredged in the early 20 ...

King's Messenger
The Corps of King's Messengers (or Corps of Queen's Messengers during the reign of a female monarch) are couriers employed by the British Foreign, Commonwealth and Development Office (FCDO). They hand-carry secret and important documents to British embassies, high commissions, and consulates around the world. Many King’s Messengers were retired Army personnel. Messengers generally travel in plain clothes in business class on scheduled airlines with their consignment. The division's official name changes depending on the gender of the reigning monarch. The safe passage of diplomatic baggage is guaranteed by Articles 27 and 36 of the Vienna Convention on Diplomatic Relations, and for reasons of state secrecy, the diplomatic bag does not go through normal airport baggage checks and must not be opened, X-rayed, weighed, or otherwise investigated by customs of a foreign state, airline security staff or anyone else. The only exception is if there is serious evidence that it might ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battleship Grey
Variations of gray or grey include achromatic grayscale shades, which lie exactly between white and black, and nearby colors with low colorfulness. A selection of a number of these various colors is shown below. Chart of computer web color grays Below is a chart showing the computer web color grays. An ''achromatic gray'' is a gray color in which the red, green, and blue codes are exactly equal. The web colors ''gray'', ''gainsboro'', ''light gray'', ''dark gray'', and ''dim gray'' are all achromatic colors. A ''chromatic gray'' is a gray color in which the red, green, and blue codes are not exactly equal, but are close to each other, which is what makes it a shade of gray. White and black The colors white and black are not usually thought of as shades of gray, but they can be thought of as shades of achromatic gray, as both contain equal amounts of red, blue and green. White is at the extreme upper end of the achromatic value scale and black is at the extreme lower end ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

King George V Graving Dock
King George V Graving Dock, also known as No. 7 Dry Dock, is a former dry dock situated in Southampton's Western Docks. It was designed by F.E. Wentworth-Shields and constructed by John Mowlem & Company and Edmund Nuttall Sons & Company. It was formally opened by King George V and Queen Mary on 26 July 1933 although the final construction work was only complete the following year. At the time of construction it was the largest graving dock in the world, a status it retained for nearly thirty years. Construction and design The dock was built as part of the westward expansion of Southampton Docks, then owned by the Southern Railway. There had previously been several dry docks in the port, each larger than its predecessor, but a larger dock was needed to accommodate the new passenger liners which were coming into service, including RMS ''Queen Mary'' () and RMS ''Queen Elizabeth'' (). The new dock cost more than £2,000,000 to construct. The design of dry docks had evolved ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King George V-class Battleship (1939)
The ''King George V''-class battleships were the most modern British battleships in commission during the Second World War. Five ships of this class were built: HMS ''King George V'' (commissioned 1940), HMS ''Prince of Wales'' (1941), HMS ''Duke of York'' (1941), HMS ''Anson'' (1942) and HMS ''Howe'' (1942). The names honoured King George V, and his sons, Edward VIII, who had been Prince of Wales, and George VI who was Duke of York before ascending to the throne; the final two ships of the class were named for prominent 18th century admirals of the Royal Navy. The Washington Naval Treaty of 1922 limited all of the number, displacement, and armament of warships built following its ratification, and this was extended by the First London Naval Treaty but these treaties were due to expire in 1936. With increased tension between Britain, the United States, Japan, France and Italy, it was supposed by the designers of these battleships that the treaty ...

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
