Argentina analyzes noise as sub search continues

Posted November 21, 2017

Argentina's navy is analysing a noise that may have come from a missing submarine with 44 crew members on board. The craft was navigating normally, underwater, at a speed of five knots toward Mar del Plata when it was last heard from, he said.

The vessel went out of contact while en route from the islands of Argentina's Tierra del Fuego to the Armada Argentina's northern base at Mar del Plata. Her father, Eduardo Krawczyk, said: "We are extremely anxious, with little news, waiting for information". The official noted that crews of submarines in distress bang on the vessel's hull to alert passing ships to their location.

"Yesterday's news was something of a respite for us, to know that there is life", Claudio Rodriguez, the brother of a crew member, said on television channel A24 on Sunday morning.

The Argentinian navy is focusing its search in an area of 35 square nautical miles about 330 miles from the coast of Argentina. "It was therefore asked to change course and go to Mar del Plata". The four aircraft were scheduled to arrive in Argentina Nov. 19.

Distress calls bring hope to search for missing Argentina sub

A naval commander told reporters that the submarine had surfaced and reported an electrical problem before it disappeared 268 miles off the coast.

Authorities say the position is in line with the path the sub would have taken to reach the base in Mar del Plata as planned and a United States military aircraft has been sent to check the area.

Argentine President Mauricio Macri said in a tweet that the country will use "all resources national and global that are necessary to find the submarine". The navy did not give details of the content of that final communication.

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.

So far, 80 percent of the area initially marked for search has shown no signs of the submarine.

The BBC reports that "It is thought that the submarine may have had communication difficulties caused by a power cut".

Weather conditions in the region have made the search hard, spokesmen said, with 6-8 meter (20-26 foot) waves prevailing there in recent days.

"We are checking and confirming that information, and we are trying to squeeze out any information that may result in something concrete to detect the location", Balbi said.

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

US satellite communications firm Iridium Communications, brought in to help with the analysis, said the signals did not originate from the submarine.

"This phase of search and rescue is critical", Balbi said.

A US Navy Bluefin AUV is deployed from a ship in 2014 in support of the search for Malaysia Airlines Flight 370.
