Nancekuke
Remote Radar Head Portreath or RRH Portreath is an air defence radar station operated by the Royal Air Force. It has a coastal location at Nancekuke Common, approximately north east of the village of Portreath in Cornwall, England. Its radar (housed in a fibre glass or ''golf ball'' protective dome) provides long-range coverage of the south western approaches to the United Kingdom. Second World War Previously known as RAF Portreath, the station was built during 1940, opened in March 1941 and had a varied career during the Second World War, initially as a RAF Fighter Command station, from October 1941 as a ferry stop-over for aircraft bound to/from North Africa and the Middle East, as a temporary stop-over for United States Army Air Forces and Royal Canadian Air Force units, and then as a RAF Coastal Command station. By the end of the war, it had run down and in May 1950 was handed back to the government by the RAF. The following squadrons were here at some point: Units: C ...

Porton Down
Porton Down is a science park in Wiltshire, England, just northeast of the village of Porton, near Salisbury. It is home to two British government facilities: a site of the Ministry of Defence's Defence Science and Technology Laboratory (Dstl) – known for over 100 years as one of the UK's most secretive and controversial military research facilities, occupying – and a site of the UK Health Security Agency. It is also home to other private and commercial science organisations, and is expanding to attract other companies. Location Porton Down is located just northeast of the village of Porton near Salisbury, in Wiltshire, England. To the northwest lies the MoD Boscombe Down airfield operated by QinetiQ. On some maps, the land surrounding the complex is identified as a "Danger Area". History of government use Porton Down opened in 1916 as the War Department Experimental Station, shortly thereafter renamed the Royal Engineers Experimental Station, for testing chemical w ...

Portreath
Portreath ( kw, Porthtreth or ) is a civil parish, village and fishing port on the north coast of Cornwall, England, United Kingdom. The village is about three miles (5 km) northwest of Redruth. The village extends along both sides of a stream valley and is centred on the harbour and beach. West of the harbour entrance and breakwater are two sandy beaches that are popular with holidaymakers, surfers and naturists. Portreath lies within the Cornwall Area of Outstanding Natural Beauty (AONB). Almost a third of Cornwall has AONB designation, with the same status and protection as a National Park. Separately, in early 2017, the village was looking to be a hedgehog-friendly village. It would join Burton Fleming in the East Riding of Yorkshire as one of a handful of hedgehog-friendly villages in the UK. History The name Portreath (meaning "sandy cove") was first recorded in 1485, and tin streaming in the valley was recorded from 1602. Devon contractor Samuel Nott was engaged to ...

RAF St Mawgan
Royal Air Force St Mawgan or more simply RAF St Mawgan is a Royal Air Force station near St Mawgan and Newquay in Cornwall, England. In 2008 the runway part of the site was handed over to Newquay Airport. The remainder of the station continues to operate under the command of the RAF. RAF St Mawgan used to have the widest military runway in the UK (300 ft) and was the home of the Cornwall Air Ambulance service and more recently 505 (Wessex) Squadron Royal Auxiliary Air Force (RAuxAF). History Second World War Opened as a civilian airfield in 1933, it was requisitioned at the outbreak of the Second World War and named RAF Trebelzue, initially as a satellite of nearby RAF St Eval, but was expanded with twin concrete runways. In February 1943 it was renamed RAF St. Mawgan and in June 1943, the United States Army Air Forces took over and carried out a number of major improvements, including a new control tower and a further extension of the main runway. The airfield was put u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marconi Electronic Systems
Marconi Electronic Systems (MES), or GEC-Marconi as it was until 1998, was the defence arm of General Electric Company (GEC). It was demerged from GEC and bought by British Aerospace (BAe) on 30 November 1999 to form BAE Systems. GEC then renamed itself Marconi plc. MES exists today as BAE Systems Electronics Limited, a subsidiary of BAE Systems, but the assets were rearranged elsewhere within that company. MES-related businesses include BAE Systems Submarine Solutions, BAE Systems Surface Ships, BAE Systems Insyte and Selex ES (now a part of Leonardo S.p.A.). History MES represented the pinnacle of GEC's defence businesses which had a heritage of almost 100 years. Following GEC's acquisition of Marconi as part of English Electric in 1968, the Marconi brand was used for its defence businesses, e.g. Marconi Space & Defence Systems (MSDS), Marconi Underwater Systems Ltd (MUSL). GEC's history of military products dates back to World War I with its contribution to the war effo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

UKADGE
The Improved United Kingdom Air Defence Ground Environment, normally shortened to either UKADGE or IUKADGE, was the Royal Air Force's (RAF) ground-controlled interception system covering the British Isles during the 1990s. It consisted of a number of ground-based radar sites, links to airborne early warning aircraft and Royal Navy ships, a telecommunications system to send digital data and voice communications on a protected network, and processing systems based on VAX-11/780 computers. The network ultimately contained a dozen long-range radars including four Marconi Martello, two General Electric TPS-592, and six Plessey AR-320. UKADGE was developed in response to concerns about its predecessor, Linesman/Mediator. Linesman started in the 1950s, when it was assumed that any air attack on the UK would be by hydrogen bomb so no effort was made to "harden" the radars or its main control centre as such effort would be futile. By the mid-1960s, with the Soviet Union reaching strateg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

VX (nerve Agent)
VX is an extremely toxic synthetic chemical compound in the organophosphorus class, specifically, a thiophosphonate. In the class of nerve agents, it was developed for military use in chemical warfare after translation of earlier discoveries of organophosphate toxicity in pesticide research. In recent years, VX was found to be the agent used in the assassination of Kim Jong-nam. In its pure form, VX is an oily, relatively non-volatile liquid that is amber-like in colour. Because of its low volatility, VX persists in environments where it is dispersed. VX, short for "venomous agent X", is one of the best known of the V nerve agents and was first discovered at Porton Down by Ranajit Ghosh in England during the early 1950s based on research first done by Gerhard Schrader, a chemist working for IG Farben in Germany during the 1930s. It is now one of a broader V-series of agents which are classified as nerve agents and have been used as a chemical weapon in various recorded dead ...

Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nerve Agent
Nerve agents, sometimes also called nerve gases, are a class of organic chemicals that disrupt the mechanisms by which nerves transfer messages to organs. The disruption is caused by the blocking of acetylcholinesterase (AChE), an enzyme that catalyzes the breakdown of acetylcholine, a neurotransmitter. Nerve agents are acetylcholinesterase inhibitors used as poison. Poisoning by a nerve agent leads to constriction of pupils, profuse salivation, convulsions, and involuntary urination and defecation, with the first symptoms appearing in seconds after exposure. Death by asphyxiation or cardiac arrest may follow in minutes due to the loss of the body's control over respiratory and other muscles. Some nerve agents are readily vaporized or aerosolized, and the primary portal of entry into the body is the respiratory system. Nerve agents can also be absorbed through the skin, requiring that those likely to be subjected to such agents wear a full body suit in addition to a respirato ...

Chemical Defence Establishment
The Defence Chemical, Biological, Radiological and Nuclear Centre (the Defence CBRN Centre or DCBRNC for short) is a United Kingdom military facility at Winterbourne Gunner in Wiltshire, south of Porton Down and about northeast of Salisbury. It is a tri-service location, with the Army being the lead service. The centre is responsible for all training issues relating to chemical, biological, radiological and nuclear (CBRN) defence and warfare for the UK's armed forces. It is also the home of the National Ambulance Resilience Unit's Training & Education Centre which, among other things, is responsible for training the NHS ambulance service's Hazardous Area Response Teams (HART). History The site was established as an element of the Porton Down research facility in 1917. Known as Porton South Camp, it served as a trench mortar experimental site. Reduced in scale immediately following the cessation of hostilities in 1918, research into chemical weapons and defence recommenced i ...
