ROTOR

ROTOR was a huge and elaborate air defence radar system built by the British Government in the early 1950s to counter possible attack by Soviet Union bombers. It was first proposed in the Cherry Report of 1949 which suggested that the 170 existing Royal Air Force radar stations be reduced to 66 sites which and the electronics extensively upgraded and relocated into nuclear bunkers. Six ''R4'' Sector Operation Control (SOC) centres provided overall control to a command hierarchy of bunkers, known as ''R3'', ''R2'' and ''R1'' bunkers. Another 28 ''Anti-Aircraft Operations Room'' (AAOR) bunkers were built for control of anti-aircraft guns. These new bunkers consumed 350,000 tons of concrete. The work was mainly carried out by the Marconi Company in several phases, called ROTOR 1, ROTOR 2 and ROTOR 3. The bunkers for the East coast, facing the direction of expected attack, were buried deep underground but west coast sites were only partially buried. The system was extensively revamped in the mid-fifties with the development of the ''Green Garlic'' radar (later called the Type 80), which allowed detection and ground control of interception to be performed using the same radar. This and the need for quicker reaction times because of the development of Soviet supersonic aircraft meant that the number of sites was further reduced. Whilst some were retained as ''Master Radar Stations'' (MRS), all of the AAOR sites and many others became government department and local authority wartime headquarters. In the mid-1960s the Master Radar Stations themselves were replaced with a new system called Linesman/Mediator. Until the end of the Cold War the sites were retained by the government but now have been sold off to private buyers or converted into museums and some transferred to the National Air Traffic Control Centre. == See also == *Faraid Head ==External links== * [http://www.blackiston.btinternet.co.uk/ The ROTOR radar system] * [http://www.secretbunker.co.uk/ R3 Anstruther bunker, now a museum]

Rotor

Rotor may refer to: * the rotating part of a machine, as in a motor, generator, alternator, a pump or a helicopter. The part of the machine that does not rotate is called the stator. * an electric motor designed to turn a receiving antenna to match the direction of the received signal. * certain cipher machines, such as the German Enigma machine, made use of rotating wheels, see rotor machine. * in US English, the disc in a disc brake. * a part in a distributor. * the ROTOR radar project, the UK's 1st national air defence system following the Second World War, incorporating some Chain Home radar stations.
