One of the most extensive Russian underwater exercise since the end of the Cold War is currently underway in the waters of the North Atlantic. Ten submarines, at least eight of them nuclear-powered, set sail from the port of Murmansk early last week before some of them passed through the Greenland-Iceland-UK Gap.

At a common strategic look, movements of the submarines are considered as remarkable incidents. Because when the tension increases, submarines leave homeports and proceeds to the positions in accordance with their country’s plans. Those submarines are now heading out into the North Atlantic with the goal being to pass west of Greenland and as far into the North Atlantic as possible.

The Sierra II class is among Russia's most capable fast attack submarines, with their titanium hulls capable of withstanding greater depths than their steel counterparts. Moscow has made at least part of the mission public, reporting that submarines are taking part in defensive and testing operations in the Barents and Norwegian sea.
