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.
