The name Royal Radar Establishment was given to the existing Radar Research Establishment following a visit by Queen Elizabeth II in 1957. Both names were abbreviated to RRE. The establishment had been formed, under its first name, in 1953 by merging the Telecommunications Research Establishment (TRE) and the Radar Research and Development Establishment (RRDE). These had worked on airborne and ground based radar, respectively. RRE was located in Malvern, Worcestershire, where both TRE and RRDE had been housed at different sites. The earlier research and development work of TRE and RRDE on radar, solid state physics, electronics, and computer hardware and software was continued in the merged establishment, and the overall scope was extended to include cryogenics and other topics.
