ROTOR was an elaborate air defence radar system built by the British Government in the early 1950s to counter possible attack by Soviet bombers. To get it operational as quickly as possible, it was initially made up primarily of WWII-era systems, notably the original Chain Home radars for the early warning role, and the AMES Type 7 for plotting and interception control. Data from these stations was sent to a network of control stations, mostly built underground, using an extensive telephone and telex network.
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.
Royal Air Force Buchan or more simply RAF Buchan is a former Royal Air Force station near Peterhead in Aberdeenshire, Scotland.
Ground-controlled interception (GCI) is an air defence tactic whereby one or more radar stations or other observational stations are linked to a command communications centre which guides interceptor aircraft to an airborne target. This tactic was pioneered during World War I by the London Air Defence Area organization, which became the Royal Air Force's Dowding system in World War II, the first national-scale system. The Luftwaffe introduced similar systems during the war, but most other combatants did not suffer the same threat of air attack and did not develop complex systems like these until the Cold War era.
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).
The British Telecom microwave network was a network of point-to-point microwave radio links in the United Kingdom, operated at first by the General Post Office, and subsequently by its successor BT plc. From the late 1950s to the 1980s it provided a large part of BT's trunk communications capacity, and carried telephone, television and radar signals and digital data, both civil and military. Its use of line-of-sight microwave transmission was particularly important during the Cold War for its resilience against nuclear attack. It was rendered obsolete, at least for normal civilian purposes, by the installation of a national optical fibre communication network with considerably higher reliability and vastly greater capacity.
Royal Air Force Lindholme or more simply RAF Lindholme is a former Royal Air Force station in South Yorkshire, England. It was located 3.9 miles (6.3 km) south of Thorne and 6.9 miles (11.1 km) north east of Doncaster and was initially called RAF Hatfield Woodhouse.
No. 131 Radar Station RAAF is a heritage-listed former Royal Australian Air Force radar station at Kooragang, City of Newcastle, New South Wales, Australia. They are also known as the Radar Igloo and Radar Buildings. They now operate as the Estuarine Interpretive Centre.
Royal Air Force Ash or more simply RAF Ash was a Royal Air Force underground control centre and radar station situated near the village of Woodnesborough, Kent, England.
RAF Ventnor is a former Royal Air Force radar station located 0.7 miles (1.1 km) north east of Ventnor on the Isle of Wight, England. It was initially constructed in 1937 as part of a World War II coastal defence programme codenamed Chain Home. The site played an important role during the Second World War, providing early warnings of incoming bomber attacks carried out by the Luftwaffe.
Remote Radar Head Trimingham or RRH Trimingham is a former TPS-77 radar station situated on the coast in the English county of Norfolk. The site is located on the coast road between Cromer and Mundesley, 1 kilometre east of the village of Trimingham but the activity has now moved to RRH Neatishead due to the threat from coastal erosion. The radar station was a satellite station of RAF Neatishead. This radar station was controlled and maintained by a section of Radar Technicians and Operators and supported by a team of Ground Engineers. Trimingham provided extensive coverage of the East coast of the United Kingdom and helped contribute to the recognised air picture and defence of the United Kingdom. The type 93 became operational on the site in April 1997.
RAF Wartling was a Royal Air Force station located near the village of Wartling in East Sussex. It was a Second World War and later Cold War Ground Controlled Interception (GCI) station built to complement the nearby Chain Home station at RAF Pevensey.
Sopley is a village and civil parish situated in the New Forest National Park of Hampshire, England. It lies on the old main road from Christchurch to Ringwood, on the east bank of the River Avon. The parish extends east as far as Thorny Hill and borders the parishes of Bransgore and Burton to the south and west respectively. It lies down the road from a small hamlet called Ripley. It includes the hamlets of Shirley, Avon and Ripley. The area is mainly rural with less than 300 dwellings.
The Battle of Britain Bunker is an underground operations room at RAF Uxbridge, formerly used by No. 11 Group Fighter Command during the Second World War. Fighter aircraft operations were controlled from there throughout the War but most notably during the Battle of Britain and on D-Day. Today it is run by Hillingdon Council as a heritage attraction with attached museum. The museum was opened in 1985, with an above ground visitor centre opened in March 2018.
RAF Portland is a former Royal Air Force and ROTOR radar station on the Isle of Portland, Dorset, England. Located close to the Verne Citadel and East Cliff, the station was established in the 1950s as part of a nationwide air defence radar system built by the British Government during the Cold War. The station became a scheduled monument in 2004 and is now the site of the community farm, Fancy's Family Farm.
The AMES Type 80, sometimes known by its development rainbow code Green Garlic, was a powerful early warning (EW) and ground-controlled interception (GCI) radar developed by the Telecommunications Research Establishment (TRE) and built by Decca for the Royal Air Force (RAF). It could reliably detect a large fighter or small bomber at ranges over 210 nautical miles, and large, high-flying aircraft were seen out to the radar horizon. It was the primary military ground-based radar in the UK from the mid-1950s into the late 1960s, providing coverage over the entire British Isles.
The AMES Type 7, also known as the Final GCI, was a ground-based radar system introduced during World War II by the Royal Air Force (RAF). The Type 7 was the first truly modern radar used by the Allies, providing a 360 degree view of the airspace around the station out to a distance of about 90 miles (140 km). It allowed fighter interceptions to be plotted directly from the radar display, a concept known as ground controlled intercept, or GCI.
The history of air traffic control in the United Kingdom began in the late 1950s, and early 1960s, when an integrated and coordinated system began, once radar had become sufficiently advanced to allow this.
Royal Air Force Hope Cove or more simply RAF Hope Cove is a former Royal Air Force radar station. It is located about 1 mile (1.6 km) south west of Salcombe on the south Devon coast, England, co-located with the former RAF Bolt Head airstrip, which was the RAF closed in 1945 but remains in service for general aviation to this day.
