The sub only had a seven day supply of air when it went missing two weeks ago. The ARA San Juan had a seven-day supply of air when it reported its last position on November 15. It had been ordered to return to a naval base in Mar del Plata after reporting that water had entered the vessel through its snorkel. "More than double the number of days have passed where it would have been possible to rescue the crew," Balbi told a news conference. "Despite the magnitude of our search it has not been possible to find the submarine."
