Plessey HF200
The HF200 is a height finder radar designed and first built by Decca Radar in 1957, and continuing sales into the 1970s after the division was purchased by Plessey in 1965. It was one of the company's successful heavy radar projects, winning the contract for many of the ROTOR stations in the UK and additional sales around the world with a total production run of about 40 examples. These served into the 1980s, and in one case, 1993, before 3D radars removed the need for separate height-finders. History Decca Heavy Radar won the contract to build the production models of the Green Garlic radar system developed by the Air Ministry's Telecommunications Research Establishment (TRE) in the early 1950s. This was just prior to the TRE's merger with their British Army counterparts to form the Radar Research Establishment in 1953. Decca's version of the Green Garlic was given the name AMES Type 80 and was among the most powerful radars of its era; the Mark III versions had a detection range ...

Decca Radar
The Decca Radar company was a British manufacturer of radar systems. There were originally two divisions, Marine and Heavy Radar, with separate product lines. The latter was sold to Plessey in 1965, and the term "Decca Radar" normally refers to the Marine division. That division remained with Decca until 1979 when it purchased by Racal to form Racal-Decca. After a series of further mergers and purchases, from 2000 the division is part of Northrop Grumman. Decca is best known for its marine radars, starting with 1949's Type 159. Their most successful line was the 1970s Bridgemaster series which continued sales into the 2000s. Under Plessey, the company was particularly successful in the US pleasure boat market. The Heavy Radar division produced the AMES Type 80 radars for the Royal Air Force, and used that technology to develop the Decca HF200 height finder radar. This led to the Decca Air Surveillance Radar, which spawned a number of adaptations for civilian and military use. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

RAF Boulmer
Royal Air Force Boulmer or RAF Boulmer is a Royal Air Force station near Alnwick in Northumberland, England, and is home to Aerospace Surveillance and Control System (ASACS) Force Command, Control and Reporting Centre (CRC) Boulmer. The School of Aerospace Battle Management and support staff was based there until 26 July 2019; it has since moved to RAF Shawbury. Until 30 September 2015, it was also home to A Flight, No. 202 Squadron RAF, who flew the Westland Sea King HAR.3 in the SAR (Search and Rescue) role. History Second World War In 1940 a decoy airfield was set up near the village of Boulmer to divert German attacks from nearby Royal Air Force (RAF) airfields such as RAF Acklington. As the air threat to the United Kingdom receded, the decoy airfield, with its grass runways and plywood and canvas Hurricanes, was abandoned. In March 1943 RAF Boulmer was reopened as a satellite airfield to house the advanced flights of No. 57 Operational Training Unit RAF (a Supermari ...

AMES Type 85
The AMES Type 85, also known by its rainbow code Blue Yeoman, was an extremely powerful early warning (EW) and fighter direction (GCI) radar used by the Royal Air Force (RAF) as part of the Linesman/Mediator radar network. First proposed in early 1958, it was eleven years before they became operational in late 1968, by which time they were already considered obsolete. The Type 85 remained the RAF's primary air defense radar until it was replaced by Marconi Martello sets in the late-1980s as part of the new IUKADGE network. In the 1950s the RAF deployed the ROTOR reporting network, and later improved this system with the AMES Type 80 radar. While these were being built, the carcinotron radar jammer was tested against it and found to completely blank out its display. At first, it was feared the carcinotron would render all long-range radars useless, but over time a number of new concepts emerged to deal with this threat. Among them was the Blue Riband radar, which used a dozen 8&nbs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linesman/Mediator
Linesman/Mediator was a dual-purpose civil and military radar network in the United Kingdom between the 1960s and 1984. The military side (Linesman) was replaced by the Improved United Kingdom Air Defence Ground Environment (IUKADGE), while the civilian side (Mediator) became the modern public-private National Air Traffic Services (NATS). In the 1950s, the Royal Air Force was installing a radar network known as ROTOR using war-era radars like Chain Home along with new command centres. A new radar, the AMES Type 80, replaced all of the ROTOR radars and command centres with a series of nine Master Control Radars and a number of associated secondary radars. While these installations were in progress in the early 1950s, Compagnie générale de la télégraphie sans fil, CSF introduced the carcinotron, which could output a radio signal at any desired frequency. This made it a very effective Radar jamming and deception, jamming system, and it appeared to render ground-based radars li ...

General Electric AN/FPS-6 Radar
The AN/FPS-6 Radar was a long-range height finding radar used by the United States Air Force's Air Defense Command. The AN/FPS-6 radar was introduced into service in the late 1950s and served as the principal height-finder radar for the United States for several decades thereafter. It was also used by the Royal Air Force alongside their AMES Type 80s. Built by General Electric, the S-band radar operated on a frequency of 2700 to 2900 MHz. Between 1953 and 1960, about 450 units of the AN/FPS-6 and the mobile AN/MPS-14 version were produced. The AN/FPS-90 and AN/FPS-116 radars were identical to the AN/FPS-6 except for receiver modifications. Operation The radar consisted of an antenna group, a transmitter group, a receiver group, and an ancillary group. Most fixed sites had a remote group, which allowed the control of the radar from inside the operations center. Also located in operations, was the anti-jam receivers. These receivers were fed with raw video from the tower receiv ... [...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] |
NADGE
The NATO Integrated Air Defense System (short: NATINADS) is a command and control network combining radars and other facilities spread throughout the NATO alliance's air defence forces. It formed in the mid-1950s and became operational in 1962 as NADGE. It has been constantly upgraded since its formation, notably with the integration of Airborne Early Warning aircraft in the 1970s. The United Kingdom maintained its own network, but was fully integrated with the network since the introduction of the Linesman/Mediator network in the 1970s. Similarly, the German network maintained an independent nature through GEADGE. Development Development was approved by the NATO Military Committee in December 1955. The system was to be based on four air defense regions (ADRs) coordinated by SACEUR (Supreme Allied Commander Europe). Starting from 1956 early warning coverage was extended across Western Europe using 18 radar stations. This part of the system was completed by 1962. Linked to existin ...

NATO
The North Atlantic Treaty Organization (NATO, ; french: Organisation du traité de l'Atlantique nord, ), also called the North Atlantic Alliance, is an intergovernmental military alliance between 30 member states – 28 European and two North American. Established in the aftermath of World War II, the organization implemented the North Atlantic Treaty, signed in Washington, D.C., on 4 April 1949. NATO is a collective security system: its independent member states agree to defend each other against attacks by third parties. During the Cold War, NATO operated as a check on the perceived threat posed by the Soviet Union. The alliance remained in place after the dissolution of the Soviet Union and has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa. The organization's motto is ''animus in consulendo liber'' (Latin for "a mind unfettered in deliberation"). NATO's main headquarters are located in Brussels, Belgium, while NATO ...

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 ...
