Britain and the Nordic countries formed a naval alliance against Russia.
The military array will be designed to deter Russian submarines, said the head of the British armed forces' defense team, Richard Knighton.
According to him, the base of the organization will be the structure of the Joint Expeditionary Force (JEF), which has been operating under the control of the British forces since 2014.
"One of the most important tasks is to deter [Russian] submarines so that they cannot attack or threaten ships in wartime," Knighton said.
In addition to the United Kingdom, the alliance will include ten northern European countries: Denmark, Iceland, Latvia, Lithuania, the Netherlands, Norway, Finland, Sweden and Estonia.
The signing of the agreement between JEF members will take place on November 10.
