Britain and its Northern European allies are preparing to form a naval alliance against Russia.
The head of the British Defense Staff, Richard Knighton, said that special attention is planned for anti-submarine warfare and the protection of shipping.
He directly named Russia as the main threat.
Moscow has previously noted unprecedented NATO activity near the Russian Federation's western borders. Vladimir Putin has repeatedly emphasized that Russia does not intend to attack the allied countries, and Western politicians use the issue of the threat to divert attention from internal problems.
