TRE - Telecommunications Research Establishment

Research leading to RDF technology in the United Kingdom was begun by Sir Henry Tizard's Aeronautical Research Committee in early 1935, responding to the urgent need to counter German bomber attacks. Robert A. Watson-Watt at the Radio Research Station, Slough, was asked to investigate a radio-based "death ray". In response, Watson-Watt and his scientific assistant, Arnold F. Wilkins, replied that it might be more practical to use radio to detect and track enemy aircraft. On 26 February 1935, a preliminary test, commonly called the Daventry Experiment, showed that radio signals reflected from an aircraft could be detected. Research funds were quickly allocated, and a development project was started in great secrecy on the Orford Ness Peninsula in Suffolk. E. G. Bowen was responsible for developing the pulsed transmitter. On 17 June 1935, the research apparatus successfully detected an aircraft at a distance of 17 miles. In August, A. P. Rowe, representing the Tizard Committee, suggested the technology be code-named RDF, meaning Range and Direction Finding.

In March 1936, the RDF research and development effort was moved to the Bawdsey Research Station located at Bawdsey Manor in Suffolk. While this operation was under the Air Ministry, the Army and Navy became involved and soon initiated their own programs.

At Bawdsey, engineers and scientists evolved the RDF technology, but Watson-Watt, the head of the team, turned from the technical side to developing a practical machine/human user interface. After watching a demonstration in which operators were attempting to locate an "attacking" bomber, he noticed that the primary problem was not technological, but information management and interpretation. Following Watson-Watt's advice, by early 1940, the RAF had built up a layered control organization that efficiently passed information along the chain of command, and was able to track large numbers of aircraft and direct interceptors to them.

Immediately after the war began in September 1939, the Air Ministry RDF development at Bawdsey was temporarily relocated to University College, Dundee in Scotland. A year later, the operation moved to near Worth Matravers in Dorset on the southern coast of England, and was named the Telecommunications Research Establishment (TRE). In a final move, the TRE relocated to Malvern College in Great Malvern, Worcestershire.

During WW2, the Malvern College premises were requisitioned by the Admiralty between October 1939 and July 1940, and the school temporarily relocated to Blenheim Palace. In 1942, its premises were again needed for governmental use, on this occasion by the TRE and, from May 1942 to July 1946, the school was housed with Harrow School. QinetiQ, a private sector successor to the government's original research facility, is still sited on former college land.

The Telecommunications Research Establishment (TRE) was the main United Kingdom research and development organization for radio navigationradarinfra-red detection for heat seeking missiles, and related work for the Royal Air Force (RAF) during WW2 and the years that followed. It was regarded as "the most brilliant and successful of the English wartime research establishments" under "Rowe, who saw more of the English scientific choices between 1935 and 1945 than any single man."

The name was changed to Radar Research Establishment in 1953, and again to the Royal Radar Establishment in 1957. This article covers the precursor organizations and the Telecommunications Research Establishment up to the time of the name change. The later work at the site is described in the separate article about RRE.

Some of the major RDF/radar equipment used by the Air Ministry is briefly described. All of the systems were given the official designation Air Ministry Experimental Station (AMES) plus a Type number; most of these are listed in this link.

By 1941 the Nazis were in full control of the British island of Alderney. They constructed fortifications to protect their grip on the Channel Islands – often with slave labor.

Diego Garcia - UK/USA

.
23-11-30 Diego Garcia: Most Controversial Island in the World - places > .US' Overseas Military Base Strategy > .

Diego Garcia is an island of the British Indian Ocean Territory, an overseas territory of the United Kingdom. It is a militarised atoll just south of the equator in the central Indian Ocean, and the largest of 60 small islands comprising the Chagos Archipelago. It was first discovered by Europeans and named by the Portuguese, settled by the French in the 1790s and transferred to British rule after the Napoleonic Wars. It was one of the "Dependencies" of the British Colony of Mauritius until the Chagos Islands were detached for inclusion in the newly created British Indian Ocean Territory (BIOT) in 1965.

In 1966, the population of the island was 924. These people were employed as contract farm workers on primarily coconut plantations owned by the Chagos-Agalega company. Although it was common for local plantation managers to allow pensioners and the disabled to remain in the islands and continue to receive housing and rations in exchange for light work, children after the age of 12 were required to work. In 1964, only 3 of a population of 963 were unemployed. In April 1967, the BIOT Administration bought out Chagos-Agalega for £600,000, thus becoming the sole property owner in the BIOT. The Crown immediately leased back the properties to Chagos-Agalega but the company terminated the lease at the end of 1967.

Between 1968 and 1973, the now unemployed farm workers were forcibly removed from Diego Garcia by the UK Government so a joint US/UK military base could be established on the island. Many were deported to Mauritius and the Seychelles, following which the United States built a large naval and military base, which has been in continuous operation since then. As of August 2018, Diego Garcia is the only inhabited island of the BIOT; the population is composed of military personnel and supporting contractors. It is one of two critical US bomber bases in the Asia Pacific region, along with Andersen Air Force Base, Guam, Pacific Ocean.

The atoll is located 3,535 km (2,197 mi) east of Tanzania's coast, 1,796 km (1,116 mi) south-southwest of the southern tip of India (at Kanyakumari), and 4,723 km (2,935 mi) west-northwest of the west coast of Australia (at Cape Range National Park, Western Australia). Diego Garcia lies at the southernmost tip of the Chagos-Laccadive Ridge, a vast underwater mountain range[7] with peaks consisting of coral reefs, atolls, and islands comprising Lakshadweep, the Maldives, and the Chagos Archipelago. Local time is UTC+6 year-round (and since then in permanent DST).

On 23 June 2017, the United Nations General Assembly (UNGA) voted in favour of referring the territorial dispute between Mauritius and the UK to the International Court of Justice (ICJ) in order to clarify the legal status of the Chagos Islands archipelago in the Indian Ocean. The motion was approved by a majority vote with 94 voting for and 15 against.

In February 2019, the International Court of Justice in The Hague ruled that the United Kingdom must transfer the islands to Mauritius as they were not legally separated from the latter in 1965. The ruling is not legally binding. In May 2019, the United Nations General Assembly affirmed the decision of the International Court of Justice and demanded that the United Kingdom withdraw its colonial administration from the Islands and cooperate with Mauritius to facilitate the resettlement of Mauritian nationals in the archipelago. In a written statement, the U.S. government said that neither the Americans nor the British have any plans to discontinue use of the military base on Diego Garcia. The statement said in a footnote: "In 2016, there were discussions between the United Kingdom and the United States concerning the continuing importance of the joint base. Neither party gave notice to terminate and the agreement remains in force until 2036".

In June 2020, a Mauritian official offered to allow the United States to retain its military base on the island if Mauritius succeeded in regaining sovereignty over the Chagos archipelago.
