“We are investigating the reasons for the lack of communication,” Argentine naval spokesman Enrique Balbi told reporters. “If there was a communication problem, the boat would have to come to the surface.”
Balbi said the submarine, which left the southern city of Ushuaia for Mar del Plata, both in Argentina, has food supply for several days and is likely to continue its journey despite communication problems.
Submarine ARA SAN JUAN, TR-1700-class diesel-electric submarine in active service with the Argentine Navy, built 1983, displacement: 2140 tonnes (surfaced) 2336 tonnes (submerged), armament torpedoes.
