Distress calls bring hope to search for missing Argentina sub

Hunt on for missing Argentine submarine

Authorities said the ship had enough food to continue on its journey to Mar del Plata but it was unclear how long the submarine could stay underwater.

A US Navy P-8A Poseidon aircraft assisting in the search was brought to the area to record an acoustic footprint of the sound.

However, it would not be unusual for storms to cause delays, Balbi said.

"We are not discounting any hypothesis", Balbi said, adding that possibilities to explain the submarine's disappearance include "a problem with communications" or with its power system. A search team was deployed to scour some 35 square miles about 330 miles off the coast of Argentina.

The sub was heading from a base in southern Argentina's Tierra del Fuego archipelago to Mar del Plata. Britain was sending a polar exploration vessel, the HMS Protector, which British officials said should arrive Sunday.

The TR-1700 class submarine had been returning from a routine mission to Ushuaia, near the southernmost tip of South America, to its base at Mar del Plata, about 400 kilometers south of Buenos Aires.

U.S. Southern Command (SOUTHCOM) directed the deployment of this equipment and personnel to Argentina to support the country's request for worldwide assistance aimed at locating the missing submarine and crew. The navy did not give details of the content of that final communication.

Distress calls bring hope to search for missing Argentina sub

A multinational armada of aircraft and vessels battled high winds and raging seas Sunday as they intensified their search for a missing Argentine submarine, after apparent attempted distress calls raised hopes the 44 crew members may still be alive.

The U.S. Navy has deployed unmanned underwater vehicles (UUV) to join in the search for the Argentine navy's submarine, A.R.A. San Juan, in South Atlantic waters.

The Argentine military has also been working with a U.S. company that specializes in satellite communication to determine the location of the submarine.

Recent bad weather in the region has made the search more hard for aircraft and ships; the Patagonia Coast is known for bad storms. He said similar conditions were expected for the next two days.

If it is immersed and can not raise a snorkel, oxygen may last about seven days.
