The ARA San Juan submarine was 432km off Argentina's coast in the South Atlantic when it sent its last signal, navy spokesman Enrique Balbi said. Authorities last had contact with submarine ARA San Juan on Wednesday as it was on a voyage from the extreme southern port of Ushuaia to the city of Mar del Plata. The Argentine sub has been missing in the Argentine Sea, and the subsequent search is entering its fifth day.
In the "worst-case scenario", the missing sub could run out of oxygen in two days, Balbi said. On Board the submarine at the moment of departure was 44 members of the crew, why the ship did not respond and that could happen - is not known.
Specialist underwater rescue equipment has arrived in Argentina from the United States and more boats and planes have also joined the search, which has been hampered by heavy winds and high waves.
A search of 80 percent of the area initially targeted for the operation turned up no sign of the vessel on the ocean surface, he said, but the crew should have ample supplies of food and oxygen.
