AI.24 Foxhunter
The AI.24 ''Foxhunter'' was an airborne radar carried by the Panavia Tornado ADV fighter aircraft (known as the Tornado F3 in Royal Air Force service) and gave it an all-weather, day and night, beyond-visual-range engagement capability. Production The radar was manufactured by GEC-Marconi subsidiaries and other partners, with major parts from Ferranti. Despite initial problems, (the radar was several years late and 60 percent over budget) successive upgrades constantly improved the RAF's Tornado F3 fleet. Development Much of the radar system and related operational software was developed at the Radar Research Laboratory of GEC-Marconi Elliott Avionic Systems Ltd., initially at the Elliott Automation plant in Borehamwood, Hertfordshire, United Kingdom, and latterly (from 1981 to 2004) as Marconi Avionics at the (formerly the Xerox site of a matrix of interconnected grey portacabins and a few factory units) facility on Monks Way, Linford Wood, Milton Keynes.

Panavia Tornado ADV
The Panavia Tornado Air Defence Variant (ADV) was a long-range, twin-engine interceptor version of the swing-wing Panavia Tornado. The aircraft's first flight was on 27 October 1979, and it entered service with the Royal Air Force (RAF) in 1986. It was also operated by the Italian Air Force (AMI) and the Royal Saudi Air Force (RSAF). The Tornado ADV was originally designed to intercept Soviet bombers as they were traversing across the North Sea with the aim of preventing a successful air-launched nuclear attack against the United Kingdom. In this capacity, it was equipped with a powerful radar and beyond-visual-range missiles; however, initial aircraft produced to the F2 standard lacked radars due to development issues. The F3 standard was the definitive variant used by the RAF, the RSAF and the AMI (which leased RAF aircraft). During its service life, the Tornado ADV received several upgrade programmes which enhanced its aerial capabilities and enabled it to perform the Suppr ...

Milton Keynes
Milton Keynes ( ) is a city and the largest settlement in Buckinghamshire, England, about north-west of London. At the 2021 Census, the population of its urban area was over . The River Great Ouse forms its northern boundary; a tributary, the River Ouzel, meanders through its linear parks and balancing lakes. Approximately 25% of the urban area is parkland or woodland and includes two Sites of Special Scientific Interest (SSSIs). In the 1960s, the UK government decided that a further generation of new towns in the South East of England was needed to relieve housing congestion in London. This new town (in planning documents, 'new city'), Milton Keynes, was to be the biggest yet, with a target population of 250,000 and a 'designated area' of about . At designation, its area incorporated the existing towns of Bletchley, Fenny Stratford, Wolverton and Stony Stratford, along with another fifteen villages and farmland in between. These settlements had an extensive historical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Electric Company
The General Electric Company (GEC) was a major British industrial conglomerate involved in consumer and defence electronics, communications, and engineering. The company was founded in 1886, was Britain's largest private employer with over 250,000 employees in the 1980s, and at its peak in the 1990s, made profits of over £1 billion a year. In June 1998, GEC sold its share of the joint venture GEC-Alsthom on the Paris stock exchange. In December 1999, GEC's defence arm, Marconi Electronic Systems, was sold to British Aerospace, forming BAE Systems. The rest of GEC, mainly telecommunications equipment manufacturing, continued as Marconi Communications. After buying several US telecoms manufacturers at the top of the market, losses following the bursting of the dot-com bubble in 2001 led to the restructuring in 2003 of Marconi plc into Marconi Corporation plc. In 2005, Ericsson acquired the bulk of that company. What was left of the business was renamed Telent. History ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Radars
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air bal ...

Rainbow Codes
The Rainbow Codes were a series of code names used to disguise the nature of various British military research projects. They were mainly used by the Ministry of Supply from the end of the Second World War until 1958, when the ministry was broken up and its functions distributed among the forces. The codes were replaced by an alphanumeric code system. History During WWII, British intelligence was able to glean details of new German technologies simply by considering their code names. For instance, when they heard of a new system known as ''Wotan'', Reginald Victor Jones asked around and found that Wotan was a one-eyed god. Based on this, he guessed it was a radio navigation system using a single radio beam. This proved correct, and the Royal Air Force was able to quickly render it useless through jamming. Wishing to avoid making this sort of mistake, Ministry of Supply (MoS) initiated a system that would be entirely random and deliberately unrelated to the program in any wa ...

Blue Circle
Blue Circle Industries was a British public company manufacturing cement. It was founded in 1900 as the Associated Portland Cement Manufacturers Ltd through the fusion of 24 cement works, mostly around on the Thames and Medway estuaries, together having around a 70% market share of the British cement market. In 1911, the British Portland Cement Manufacturers Ltd was formed by the addition of a further 35 companies, creating a company with an initial 80% of the British cement market. Subsequently, the company expanded overseas, predominantly into commonwealth countries and South and Central America. The energy crisis of the 1970 caused the contraction of the company, and the sale of its overseas plants. In 1978, the company's name was changed to ''Blue Circle''. In 2001 the company was bought by Lafarge. History The company was founded in 1900 as ''Associated Portland Cement Manufacturers Ltd'' by the amalgamation of 24 cement companies, owning 35 cement plants, all but two o ...

Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Financial Times
The ''Financial Times'' (''FT'') is a British daily newspaper printed in broadsheet and published digitally that focuses on business and economic current affairs. Based in London, England, the paper is owned by a Japanese holding company, Nikkei, with core editorial offices across Britain, the United States and continental Europe. In July 2015, Pearson sold the publication to Nikkei for £844 million (US$1.32 billion) after owning it since 1957. In 2019, it reported one million paying subscriptions, three-quarters of which were digital subscriptions. The newspaper has a prominent focus on financial journalism and economic analysis over generalist reporting, drawing both criticism and acclaim. The daily sponsors an annual book award and publishes a " Person of the Year" feature. The paper was founded in January 1888 as the ''London Financial Guide'' before rebranding a month later as the ''Financial Times''. It was first circulated around metropolitan London by James Sherid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Blackburn Buccaneer
The Blackburn Buccaneer is a British carrier-capable attack aircraft designed in the 1950s for the Royal Navy (RN). Designed and initially produced by Blackburn Aircraft at Brough, it was later officially known as the Hawker Siddeley Buccaneer when Blackburn became a part of the Hawker Siddeley Group, but this name is rarely used. The Buccaneer was originally designed in response to the Soviet Union's ''Sverdlov''-class cruiser construction programme. Instead of building a new fleet of its own, the Royal Navy could use the Buccaneer to attack these ships by approaching at low altitudes below the ship's radar horizon. The Buccaneer could attack using a nuclear bomb, or conventional weapons. It was later intended to carry short-range anti-shipping missiles to improve its survivability against more modern ship-based anti-aircraft weapons. The Buccaneer entered Royal Navy service in 1962. The initial production aircraft suffered a series of accidents due to insufficient engine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawker Siddeley
Hawker Siddeley was a group of British manufacturing companies engaged in aircraft production. Hawker Siddeley combined the legacies of several British aircraft manufacturers, emerging through a series of mergers and acquisitions as one of only two such major British companies in the 1960s. In 1977, Hawker Siddeley became a founding component of the nationalised British Aerospace (BAe). Hawker Siddeley also operated in other industrial markets, such as locomotive building (through its ownership of Brush Traction) and diesel engine manufacture (through its ownership of Lister Petter). The company was once a constituent of the FTSE 100 Index. History Origins Hawker Siddeley Aircraft was formed in 1935 as a result of the purchase by Hawker Aircraft of the companies of J. D. Siddeley, the automotive and engine builder Armstrong Siddeley and the aircraft manufacturer Armstrong Whitworth Aircraft. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marconi Avionics
BAE Systems Avionics was the avionics unit of BAE Systems until 2005, at which time it was transferred to SELEX Sensors and Airborne Systems S.p.A. (initially 75% Finmeccanica and 25% BAE Systems, but since March 2007 fully owned by Finmeccanica). Selex S&AS became SELEX Galileo in 2008 and from January 2013 (following a merger with other Finmeccanica companies SELEX Sistemi Integrati and Selex Elsag) traded as Selex ES. It then merged into Leonardo S.p.A.'s land and naval defence electronics division on 1 January 2016. The business had its UK headquarters in Basildon, Essex, England. History BAE Systems Avionics has a rich heritage which dates back to 1909 when the Elliott and Marconi companies began to fit aircraft with systems (beginning with embryonic air to ground communications). By 1913 Elliot's avionics product lines advanced to gyroscopes, weapon sights and altimeters. Timeline *1804 - William Elliott establishes a company manufacturing scientific and surveying i ...
