Signals Research and Development Establishment

The Signals Research and Development Establishment (SRDE) was a British government military research establishment, based in Christchurch, Dorset from 1943 until it merged with the Royal Radar Establishment (RRE) in Malvern, Worcestershire to form the Royal Signals and Radar Establishment (RSRE) in 1976. Its focus was military communications (signals).

The establishment had its origins in the Royal Engineers Wireless Telegraphy Experimental Section founded at Aldershot in the very early part of the twentieth century. It moved to Woolwich, initially into the former Royal Dockyard (at that time a military stores depot) where it formed part of the Inspectorate of Royal Engineers Stores, before moving on to Woolwich Common; in 1914 it was operating out of a van, but in 1916 it settled into its own premises there, becoming the Signals Experimental Establishment. The establishment was renamed SRDE at the start of the Second World War; it moved briefly to Horsham during the war before settling in Christchurch in 1943. The Woolwich buildings then became an Atomic Weapons Research Establishment.

SRDE remained in Christchurch until 1976 when, under the Director of John Mills, it merged with the Royal Radar Establishment (RRE) and SERL (Services Electronic Research Laboratory formerly at Baldock, Hertfordshire) and relocated to Malvern, Worcestershire to form the Royal Signals and Radar Establishment (RSRE).
