Russia deployed at least 10 submarines in the North Atlantic during the largest exercise since the Cold War, Norwegian intelligence said.

"No less than 10 Russian naval submarines are participating in the exercise, eight of which run on nuclear power. The goal of the submarines is to travel the farthest out of the Atlantic Ocean without being detected," Norwegian broadcaster NRK yesterday said intelligence sources said the country.

This submarine force seems to originate from the bases of the Northern Fleet in the Murmansk region, northern Russia and has been hiding underwater since leaving port.

The exercise also seems to test new weapons and evaluate the ability of submarines in the long-term of current submarines in Russia. It could also help Russia test US and NATO seabed surveillance capabilities in the GIUK Strait, a strategic bottleneck between Greenland, Iceland and Britain.

"If Russian submarines can move through here undetected, they can deploy to areas on the Atlantic Ocean without fear of being followed by the enemy. That allows Russian submarines to suddenly attack. naval and naval fleets, as well as conducting accurate strikes on enemy ground targets during the war, "said military expert Tyler Rogoway.

The Russian Defense Ministry has not commented on this information.
