Officers from the UK’s Royal Navy searched for the missing Argentine submarine San Juan in the South Atlantic on Monday, November 20.

This video, shared by the UK’s Ministry of Defence on behalf of the Royal Navy, show the view from inside the HMS Protector, the Royal Navy’s ice patrol ship, as it endured waves of up to 10 metres. The HMS Protector arrived in the South Atlantic on November 19, following a request for assistance from the Argentine government, the Royal Navy said. The Protector was joined by the Royal Navy’s specialist Submarine Parachute Assistance Group and the Falklands Islands patrol vessel HMS Clyde to assist with the search efforts.

The UK’s Royal Navy was joined by international naval teams from the US, Chile, Brazil, Colombia, Uruguay and Peru for the rescue mission. The search for San Juan, which had 44 people on board, had become increasingly desperate after it last made contact with navy officials on Wednesday, November 15, ABC reported. The vessel only had enough oxygen supply for seven days if submerged, the news broadcaster reported. Credit: Twitter/HMS Protector via Storyful
