Russian Submarine hit Royal Navy Warship Sonar in the North Atlantic
The incident happened in late 2020 and was captured by a Channel 5 TV crew filming a documentary.
A Russian submarine collided with a Royal Navy warship's sonar on patrol in the North Atlantic, the Ministry of Defence has confirmed, BBC reports.
HMS Northumberland was searching for the submarine in the Arctic Circle after it disappeared from the ship's radar, according to Channel 5, which was filming for its Warship: Life at Sea series.
The film cameras captured the crew shouting: "What the hell was that?".
It is not clear what, if any, damage was suffered by the Russian vessel but the warship had to return to port in Scotland to replace the damaged equipment.
A spokesman for the MoD said: "In late 2020 a Russian submarine being tracked by HMS Northumberland came into contact with her towed array sonar.
"The Royal Navy regularly tracks foreign ships and submarines in order to ensure the defence of the United Kingdom."
