In 1959, Portland's Admiralty Gunnery Establishment was transferred to Portsdown Hill, allowing the research at Portland to focus on anti-submarine research and underwater weapons. The formation of the Admiralty Underwater Weapons Establishment was an amalgamation of a number of Admiralty research sites, including the Underwater Countermeasures and Weapons Establishment at Havant, the Torpedo Experimental Establishment at Greenock and the Underwater Launching Establishment at Bournemouth. This amalgamation saw all research into underwater weapons and detection systems concentrated at Portland, with two primary sites forming the AUWE: AUWE (North) and AUWE (South). The North site, located at Portland's Naval Base was formerly the HM Underwater Detection Establishment.
