# E-tjenesten The Etterretningstjenesten (Norwegian Intelligence Service) is Norway's military foreign intelligence agency — responsible for signals intelligence, military intelligence, and monitoring threats in Norway's strategic neighborhood, particularly Russian military activity in the Arctic and North Atlantic. Norway participates in the [[Nine Eyes]] intelligence-sharing arrangement. Norway's geography — sharing a 196-kilometer border with Russia in the Arctic — gives E-tjenesten unique collection opportunities. Norwegian listening stations have monitored Russian Northern Fleet submarine and naval activity since the Cold War, providing intelligence of high value to [[NATO]] and the [[Five Eyes Alliance]]. The agency's Marjata-class intelligence vessels patrol the Barents Sea collecting signals intelligence on Russian military operations. ## See Also - [[Nine Eyes]] — the intelligence-sharing tier - [[NSA]] — primary signals intelligence partner - [[Global Intelligence Hub]] — full agency index
