“At the end of 2020, a Russian submarine tracked by HMS Northumberland was in contact (with this unit),” the ministry said in a statement. The Russian ship was supposed to collide with a sonar device that was towed several hundred meters behind its hull.

“The Royal Navy regularly targets foreign ships and submarines to defend Britain,” it was reported. It was also reported that the collision is unlikely to have been intentional.

In recent years, there has been an increase in the activity of Russian submarines. The British Navy regularly patrols the North Atlantic.

The Department of Defense does not usually comment on the operations carried out, but the 2020 incident was captured on cameras by a crew filming a documentary near the scene.
