HMS Savage (G20)
HMS ''Savage'' was an S and T-class destroyer, S-class destroyer of the Royal Navy launched on 24 September 1942. The vessel was adopted by the town of Burton upon Trent. ''Savage'' differed from the rest of the class in being fitted with a new gun, with a twin mounting for the QF 4.5-inch Mk I – V naval gun, QF Mk III gun forward and two single QF Mk IV guns aft. The twin mount was taken from spares for the aircraft carrier . Initially serving as part of the destroyer escort screen for capital ships, ''Savage'' joined Operation Camera off the Norwegian coast, an unsuccessful diversionary expedition to distract the enemy from the Allied invasion of Sicily, invasion of Sicily, and escorted from Gibraltar to Scapa Flow. However, for the majority of the ship's career, ''Savage'' escorted Arctic convoys of World War II, convoys to the Soviet Union. In December 1943, the destroyer took part in the Battle of the North Cape which saw the destruction of the . After the war, ''Savage' ...

R And W Hawthorn
R and W Hawthorn Ltd was a locomotive manufacturer in Newcastle upon Tyne, England, from 1817 until 1885. Locomotive building Robert Hawthorn first began business at Forth Bank Works in 1817, building marine and stationary steam engines. In 1820, his brother William joined him and the firm became R and W Hawthorn. Possibly after having attended the Rainhill Trials in 1829, they became interested in locomotives, and sold their first engine in 1831. Printed and online sources claim this to be ''Mödling'' for the Vienna Gloggnitz railway. That is wrong, that locomotive was delivered in 1841. The 1831 order was placed by the Stockton and Darlington Railway. There followed a number of orders for the Stockton and Darlington Railway. They were great innovators - not always successfully - and their locos had many original features. In 1838 two were built for the Isambard Kingdom Brunel#Great Western Railway, broad gauge Great Western Railway to the patent of Thomas Elliot Harrison, T.&n ...

Burton Upon Trent
Burton upon Trent, also known as Burton-on-Trent or simply Burton, is a market town in the borough of East Staffordshire in the county of Staffordshire, England, close to the border with Derbyshire. In United Kingdom Census 2011, 2011, it had a population of 72,299. The demonym for residents of the town is ''Burtonian''. Burton is located south-west of Derby, north-west of Leicester, west-south-west of Nottingham and south of the southern entrance to the Peak District National Park. Burton is Brewers of Burton, known for its brewing. The town grew up around Burton Abbey. Burton Bridge was also the site of two battles, in Battle of Burton Bridge (1322), 1322, when Edward II of England, Edward II defeated the rebel Thomas, Earl of Lancaster, Earl of Lancaster and in Battle of Burton Bridge (1643), 1643 when royalists captured the town during the First English Civil War. William Paget, 1st Baron Paget, William Lord Paget and his descendants were responsible for extending the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 aft ... [...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 designed for flatwater racing may have length to beam ratios as high as 30:1, while a cor ...

Waterline Length
A vessel's length at the waterline (abbreviated to L.W.L)Note: originally Load Waterline Length is the length of a ship or boat at the level where it sits in the water (the ''waterline''). The LWL will be shorter than the length of the boat overall (''length overall'' or LOA) as most boats have bows and stern protrusions that make the LOA greater than the LWL. As a ship becomes more loaded, it will sit lower in the water and its ambient waterline length may change; but the registered L.W.L it is measured from a default load condition. This measure is significant in determining several of a vessel's properties, such as how much water it displaces, where the bow and stern waves occur, hull speed, amount of bottom-paint needed, etc. Traditionally, a stripe called the "boot top" is painted around the hull just above the waterline. In sailing boats, longer waterline length will usually enable a greater maximum speed, because it allows greater sail area, without increasing beam or d ...

Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

J-, K- And N-class Destroyer
The J, K and N class consisted of 24 destroyers built for the Royal Navy beginning in 1938. They were a return to a smaller vessel, with a heavier torpedo armament, after the that emphasised guns over torpedoes. The ships were built in three flotillas or groups, each consisting of eight ships with names beginning with "J", "K" and "N". The flag superior of the pennant numbers changed from "F" to "G" in 1940. The ships were modified throughout their wartime service, particularly their anti-aircraft (AA) guns; they were also fitted with radar. Design history The design was intended as a smaller follow-on from the preceding Tribal class, and incorporated one radical new idea that was a departure from all previous Royal Navy destroyer designs. That was the adoption of a two boiler room layout. This reduced hull length and allowed for a single funnel, both reducing the profile and increasing the arcs of fire of the light anti-aircraft (AA) weapons. However, this also increased vu ...

Anti-submarine Warfare
Anti-submarine warfare (ASW, or in older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involved a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
War Emergency Programme Destroyers
The War Emergency Programme destroyers were destroyers built for the British Royal Navy during World War I and World War II. World War I emergency programmes The 323 destroyers ordered during the First World War belonged to several different classes and were the subject of 14 separate War Programmes between 1914 and 1918. 40 of these were cancelled at the end of the war. The total excludes destroyers building in UK for other navies which were purchased for the Royal Navy following the outbreak of war. World War II emergency programme The 112 destroyers built during the Second World War were based on the hull and machinery of the earlier J-, K- and N-class destroyers of the 1930s. Each of the fourteen flotillas produced consisted of eight destroyers. Due to supply problems and the persistent failure by the Royal Navy to develop a suitable dual-purpose weapon for destroyers, they were fitted with whatever armament was available. Advances in radar and weaponry were incorporated as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Admiralty
The Admiralty was a department of the Government of the United Kingdom responsible for the command of the Royal Navy until 1964, historically under its titular head, the Lord High Admiral – one of the Great Officers of State. For much of its history, from the early 18th century until its abolition, the role of the Lord High Admiral was almost invariably put "in commission" and exercised by the Lords Commissioner of the Admiralty, who sat on the governing Board of Admiralty, rather than by a single person. The Admiralty was replaced by the Admiralty Board in 1964, as part of the reforms that created the Ministry of Defence and its Navy Department (later Navy Command). Before the Acts of Union 1707, the Office of the Admiralty and Marine Affairs administered the Royal Navy of the Kingdom of England, which merged with the Royal Scots Navy and the absorbed the responsibilities of the Lord High Admiral of the Kingdom of Scotland with the unification of the Kingdom of Great ...

Ship Breaking
Ship-breaking (also known as ship recycling, ship demolition, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships for either a source of parts, which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking is sustainable, there are concerns about the use by poorer countries without stringent environmental legislation. It is also labour-intensive, and considered one of the world's most dangerous industries. In 2012, roughly 1,250 ocean ships were broken down, and their average age was ...

Scapa Flow
Scapa Flow viewed from its eastern end in June 2009 Scapa Flow (; ) is a body of water in the Orkney Islands, Scotland, sheltered by the islands of Mainland, Graemsay, Burray,S. C. George, ''Jutland to Junkyard'', 1973. South Ronaldsay and Hoy. Its sheltered waters have played an important role in travel, trade and conflict throughout the centuries. Vikings anchored their longships in Scapa Flow more than a thousand years ago. It was the United Kingdom's chief naval base during the First and Second World Wars, but the facility was closed in 1956. Scapa Flow has a shallow sandy bottom not deeper than and most of it is about deep; it is one of the great natural harbours and anchorages of the world, with sufficient space to hold a number of navies. The harbour has an area of and contains just under 1 billion cubic metres of water. Since the scuttling of the German fleet after World War I, its wrecks and their marine habitats form an internationally acclaimed diving lo ...
