Waterlip was acquired as a test site in the 1960s but problems led to testing being transferred to a site at Vobster. However, further problems there led to testing resuming at Waterlip. The Newport site was closed and manufacturing transferred back to Templecombe. In addition there have been sites in Bath (due to the then-proximity to MoD offices in and around the city, now entirely moved to DESG MoD Abbey Wood) for Prime Contract Management and a Joint Plessey Ferranti Office at Portland to support the Admiralty Research Establishment, but both are now closed. Plessey Naval Systems also had a site at Carlsbad California for USN support. Church Crookham One of the sites of Ferranti Thomson Sonar Systems, but a relatively small site within Thales. The Church Crookham site housed a production and test facility for towed array sonars and submarine flank arrays, a design department, and a special projects section. It was involved in Sonar 2076, and for a period provided acoustic calibration services for naval vessels. Now closed. TUS Pty (Australia) Meadowbank This was the main manufacturing facility until 1995 when it was transferred to Rydalmere. The Meadowbank facility has since closed and has been redeveloped into residential apartments. Rydalmere This is the headquarters of TUS in Australia.
