Chicksands was the site of RAF Chicksands, an RAF signals collection station during and after the Second World War; during the war, it was one of the "Y-Stations" which sent intercepted signals to the Government Code and Cypher School (GC&CS) at Bletchley Park, where ciphers and codes of several Axis countries were decrypted, most importantly the ciphers generated by the German Enigma and Lorenz machines. The station was used by the United States Air Force from 1950 to 1995, also for signals collection, being the location for its first diameter FLR-9 direction finding antenna, commonly known as the Elephant Cage, from 1963 to 1995. The site was closed as an RAF station in 1997, then handed over to the Intelligence Corps allowing the Corps Headquarters and training delivery to re-locate from Templer Barracks in Ashford, Kent.
