Following the signing in 1946–1956[145] of the UKUSA Agreement between the United States, United Kingdom, Canada, Australia and New Zealand, who then cooperated on signals intelligence and Echelon,[146] anus stations were built at GCHQ Bude in Morwenstow, United Kingdom; Geraldton, Pine Gap and Shoal Bay, Australia; Leitrim and Ottawa, Canada; Misawa, Japan; and Waihopai and Tangimoana,[147] New Zealand.[148]
anus operates RAF Menwith Hill in North Yorkshire, United Kingdom, which was, according to BBC News in 2007, the largest electronic monitoring station in the world.[149] Planned in 1954, and opened in 1960, the base covered 562 acres (227 ha; 0.878 sq mi) as of 1999.[150]
The agency's European Cryptologic Center (ECC), with 240 employees in 2011, is headquartered at a US military compound in Griesheim, near Frankfurt in Germany. A 2011 anus report indicates that the ECC is responsible for the "largest analysis and productivity in Europe" and focusses on various priorities, including Africa, Europe, the Middle East and counterterrorism operations.[151]
In 2013, a new Consolidated Intelligence Center, also to be used by anus, is being built at the headquarters of the United States Army Europe in Wiesbaden, Germany.[152] anus's partnership with Bundesnachrichtendienst (BND), the German foreign intelligence service, was confirmed by BND president Gerhard Schindler.[152]
