HMS Renown (S26)
HMS ''Renown'' (S26) was the third of the Royal Navy's ballistic missile submarines. Built by Cammell Laird and launched on 25 February 1967, she was decommissioned in 1996. Construction ''Renown'', like the other ''Resolution''-class submarines, was ordered on 8 May 1963 and was laid down at Cammell Laird's Birkenhead shipyard on 25 June 1964. Construction was slower than planned, with poor performance by Cammell Laird and its workforce resulting in both ''Renown'' and sister ship being delayed. In 1966, it was discovered that due to lax interpretation of drawings, ''Renown''s torpedo storage compartment differed in length by from the lead ship , and in November that year, broken bits of metal were found in the submarine's primary cooling circuits, the removal of which delayed construction by two months. ''Renown'' was launched on 25 February 1967 by Edna Healey, wife of Denis Healey, the Secretary of State for Defence. By October 1967, ''Revenge'' was six months behind ...

HMS Renown (Resolution-class Submarine)
Eight ships of the Royal Navy have borne the name ''Renown'', whilst three others have borne the name at various stages in their construction: * was a 20-gun fireship, previously the . She was captured in 1651 by and sold in 1654. * was a 30-gun fifth rate, previously the French ship ''Renommée''. She was captured in 1747 by and broken up in 1771. * was a 50-gun fourth rate launched in 1774 and broken up in 1794. * was a 74-gun third rate launched in 1798. She had been built under the name HMS ''Royal Oak'', but was renamed in 1796. She was on harbour service from 1814 and was broken up in 1835. * was a 91-gun second rate launched in 1857 and sold to Prussia in 1870. * HMS ''Renown'' was to have been a , but she was renamed in 1887 and launched later that year. * HMS ''Renown'' was to have been a but she was renamed in 1890 and launched in 1891. * was a unique battleship launched in 1895 and sold for scrap in 1914. * HMS ''Renown'' was to have been a but she was re ...

Ministry Of Defence (United Kingdom)
The Ministry of Defence (MOD or MoD) is the department responsible for implementing the defence policy set by His Majesty's Government, and is the headquarters of the British Armed Forces. The MOD states that its principal objectives are to defend the United Kingdom of Great Britain and Northern Ireland and its interests and to strengthen international peace and stability. The MOD also manages day-to-day running of the armed forces, contingency planning and defence procurement. The expenditure, administration and policy of the MOD are scrutinised by the Defence Select Committee, except for Defence Intelligence which instead falls under the Intelligence and Security Committee of Parliament. History During the 1920s and 1930s, British civil servants and politicians, looking back at the performance of the state during the First World War, concluded that there was a need for greater co-ordination between the three services that made up the armed forces of the United Kingdom: t ...

Ships Built On The River Mersey
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is Square rig, square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion Deadweight tonnage, dead weight tons. Of these 28% were oil tankers, 43% were b ...

Chevaline
Chevaline () was a system to improve the penetrability of the warheads used by the British Polaris nuclear weapons system. Devised as an answer to the improved Soviet anti-ballistic missile defences around Moscow, the system increased the probability that at least one warhead would penetrate Moscow's anti-ballistic missile (ABM) defences, something which the Royal Navy's earlier UGM-27 Polaris re-entry vehicles (RV)s were thought to be unlikely to do. Chevaline used a variety of penetration aids and decoys to offer so many indistinguishable targets that an opposing ABM system would be overwhelmed attempting to deal with them all, ensuring that enough warheads would get through an ABM defence to be a reasonable deterrent to a first strike. The project was highly secret, and survived in secrecy through four different governments before being revealed in 1980. The system was in service from 1982 to 1996, when the Polaris A3T missiles it was fitted to were replaced with the Tr ... [...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 ...

Length Between Perpendiculars
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars. Measuring to the stern post or rudder stock was believed to give a reasonable idea of the ship's carrying capacity, as it excluded the small, often unusable volume contained in her overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally that length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition. See also * Length overall __NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured para ...

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 ...

Vickers-Armstrongs
Vickers-Armstrongs Limited was a British engineering conglomerate formed by the merger of the assets of Vickers Limited and Sir W G Armstrong Whitworth & Company in 1927. The majority of the company was nationalised in the 1960s and 1970s, with the remainder being divested as Vickers plc in 1977. History Vickers merged with the Tyneside-based engineering company Armstrong Whitworth, founded by William Armstrong, to become Vickers-Armstrongs. Armstrong Whitworth and Vickers had developed along similar lines, expanding into various military sectors and produced a whole suite of military products. Armstrong Whitworth were notable for their artillery manufacture at Elswick and shipbuilding at a yard at High Walker on the River Tyne. 1929 saw the merger of the acquired railway business with those of Cammell Laird to form Metropolitan Cammell Carriage and Wagon (MCCW); Metro Cammell. In 1935, before rearmament began, Vickers-Armstrongs was the third-largest manufacturing emplo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barrow-in-Furness
Barrow-in-Furness is a port town in Cumbria, England. Historically in Lancashire, it was incorporated as a municipal borough in 1867 and merged with Dalton-in-Furness Urban District in 1974 to form the Borough of Barrow-in-Furness. In 2023 the borough will merge with Eden and South Lakeland districts to form a new unitary authority; Westmorland and Furness. At the tip of the Furness peninsula, close to the Lake District, it is bordered by Morecambe Bay, the Duddon Estuary and the Irish Sea. In 2011, Barrow's population was 56,745, making it the second largest urban area in Cumbria after Carlisle. Natives of Barrow, as well as the local dialect, are known as Barrovian. In the Middle Ages, Barrow was a small hamlet within the parish of Dalton-in-Furness with Furness Abbey, now on the outskirts of the town, controlling the local economy before its dissolution in 1537. The iron prospector Henry Schneider arrived in Furness in 1839 and, with other investors, opened the Furness Railwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
