Whale with harness could be Russian weapon, say Norwegian experts

However, a 2017 report by TV Zvezda, a station owned by the defence ministry, revealed that the Russian navy has again been training beluga whales, seals and bottlenose dolphins for military purposes in polar waters. The recent research and training was done by Murmansk Sea Biology Research Institute in northern Russia on behalf of the navy to see if beluga whales could be used to “guard entrances to naval bases’” in arctic regions, “assist deepwater divers and if necessary kill any strangers who enter their territory”. During their research the Murmansk sea biology research institute concluded dolphins and seals were much more suited to the training and arctic climates than the beluga whales.
