the British Army heard of their efforts and formed a group to work with them to develop ground-based applications. The first project of this "Army Cell" was a ranging system for anti-aircraft artillery, but they soon added the Coast Defence radars and began work on the proximity fuse. At the outbreak of the war in 1939, the location of Bawdsey, right on the east coast, was considered far too exposed to attack. The Air Ministry team quickly moved to Dundee in Scotland, where the former Air Ministry Experimental Station became the Air Ministry Research Establishment (AMRE). The Army group moved to Christchurch, outside Bournemouth, becoming the Air Defence Experimental Establishment (ADEE). The facilities in Dundee proved far too small and isolated, and in May 1940 they moved again, this time to Worth Matravers on the south coast of England, also a short distance from Bournemouth. This was accompanied by yet another renaming, now becoming the Telecommunications Research Establishment (TRE). Ultimately they began to worry that this location was also too exposed, and when they heard a German paratroop unit had moved to France directly across the English Channel, they decided to move once again. The ADEE, by this time once again renamed to the Air Defence Research and Development (ADRDE), moved to underutilized Air Ministry buildings on the north side of Malvern in May 1942. This, of course, resulted in yet another name change to the RRDE. The TRE followed shortly thereafter, taking up residence in buildings across from Malvern College on the south side of town. TRE was part of the Ministry of Supply and, when it was formed, so was RRE. In 1959, control passed to the Ministry of Aviation. When this was abolished in 1967, control passed to the Ministry of Technology, then to the Ministry of Aviation Supply, in 1970, and to the Ministry of Defence in 1971. In 1976 RRE merged with the Signals Research and Development Establishment (SRDE) to form the Royal Signals and Radar Establishment (RSRE), which became part of the Defence Research Agency (DRA) in 1991. Later (1995), DRA was absorbed into DERA, the Defence Evaluation and Research Agency. DERA split on 2 June 2001 into two parts, a government body called Dstl (Defence Science and Technology Laboratory) and a company destined for privatisation, which became QinetiQ. The technical departments of RRE were grouped, initially, into six Divisions: airborne radar, ground radar,
