RAF Bawdsey
When the research group moved to Dundee in September 1939, the radar station was left active under the name RAF Bawdsey.Bawdsey Manor, dating from 1886, was taken over in March 1936 by the Air Ministry for developing the Chain Home (CH) RDF (radar) system.When war was declared in September 1939, fears of a possible commando raid on the group led to the development activities being relocated, first to Dundee, Scotland, and later to Worth Matravers near Swanage in Dorset on the southern coast of England, where they became the Telecommunications Research Establishment (TRE).In the 1950s, the Bawdsey CH station was upgraded as part of the ROTOR programme and gained an underground control centre with living quarters and air filtration to make it capable of operating during nuclear attack.[2] The remains of the site are still fairly well preserved and will undergo restoration in 2017 due to a £1.4 million Lottery Grant.
