HMS Hampshire (D06)
HMS ''Hampshire'' was a destroyer of the Royal Navy. Laid down, in March 1959 a couple of weeks behind the class leader , she was classified as a guided missile destroyer, as the Sea Lords regarded the concept of the cruiser and big gun ship as discredited by the perceived failure of the and the obsolescence of the heavy gun. The description of guided missile destroyer seemed more likely to win approval from the Treasury and Government for an adequate number of warships the size of small cruisers, which could play many traditional cruiser flagship and command functions, but had no armour around its gun and missile magazine. Construction and design ''Hampshire'' was one of two County-class destroyers ordered under the British Admiralty's 1955–56 shipbuilding programme. She was laid down at John Brown & Company's Clydebank shipyard on 26 March 1959 and launched by Princess Margaret on 16 March 1961. The ship was completed on 15 March 1963. ''Hampshire'' was long overal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Yarmouth (F101)
HMS ''Yarmouth'' was the first modified Type 12 frigate of the Rothesay class frigate, ''Rothesay'' class to enter service with the Royal Navy. She was rammed in the Cod Wars, Third Cod War by the Icelandic Coast Guard, Icelandic gunboat ''ICGV Baldur (II), Baldur'' and had to limp away from the patrol area for repairs. During the Falklands War, ''Yarmouth'' took part in the only ship to ship engagement of the war, when she and HMS Brilliant (F90), HMS ''Brilliant'' shelled the Argentine coaster ARA ''Monsunen''. In the last action of the conflict, ''Yarmouth'' and HMS Endurance (1967), HMS ''Endurance'' recaptured the Operation Keyhole, South Sandwich Islands. Design The ''Rothesay''-class was an improved version of the Whitby-class frigate, ''Whitby''-class anti-submarine frigate, with nine ''Rothesay''s ordered in the 1954–55 shipbuilding programme for the Royal Navy to supplement the six ''Whitby''s. ''Yarmouth'' was length overall, long overall and length between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lords Commissioners Of The Admiralty
The Board of Admiralty (1628–1964) was established in 1628 when Charles I put the office of Lord High Admiral into commission. As that position was not always occupied, the purpose was to enable management of the day-to-day operational requirements of the Royal Navy; at that point administrative control of the navy was still the responsibility of the Navy Board, established in 1546. This system remained in place until 1832, when the Board of Admiralty became the sole authority charged with both administrative and operational control of the navy when the Navy Board was abolished. The term Admiralty has become synonymous with the command and control of the Royal Navy, partly personified in the Board of Admiralty and in the Admiralty buildings in London from where operations were in large part directed. It existed until 1964 when the office of First Lord of the Admiralty was finally abolished and the functions of the Lords Commissioners were transferred to the new Admiralty B ...

Gas Turbine
A gas turbine, also called a combustion turbine, is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller ( turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission ( turboshaft), marine propeller or electrical generator (power turbine). Grea ...

Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil- ... [...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" (or "load lines"). A ...

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] |
Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells In watercraft, a racing shell (also referred to as just a ''fine boat'' (UK) or just ' ...

Princess Margaret, Countess Of Snowdon
Princess Margaret, Countess of Snowdon, (Margaret Rose; 21 August 1930 – 9 February 2002) was the younger daughter of King George VI and Queen Elizabeth The Queen Mother, and the younger sister and only sibling of Queen Elizabeth II. Margaret was born when her parents were the Duke and Duchess of York, and she spent much of her childhood with them and her elder sister. Her life changed at the age of six, when her father ascended the British throne following the abdication of his brother Edward VIII. Margaret's sister became heir presumptive, with Margaret second in line to the throne. Her position in the line of succession diminished over the following decades as Elizabeth's children and grandchildren were born. During the Second World War, the two sisters stayed at Windsor Castle despite suggestions to evacuate them to Canada. During the war years, Margaret was too young to perform official duties and continued her education, being nine years old when the ...

Ceremonial Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow (ship), bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widel ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
