Argentina says satellite calls detected, likely from missing submarine with 44 crew

The last confirmed location of the German-built ARA San Juan was 432km off Argentina’s southern Atlantic coast early on Wednesday.

Hopes that 44 crew members of a missing Argentine navy submarine may be found alive rose after the defence ministry said the vessel likely tried to communicate via satellite on Saturday as an international search mission was underway in the stormy South Atlantic.

The ministry said seven failed “satellite calls” that it believes came from the ARA San Juan submarine were detected in a likely sign the crew was trying to re-establish contact.

The signals, in the late morning and early afternoon, lasted between four and 36 seconds, the ministry said. Argentina is working on tracing the location with an unnamed US company specialised in satellite communications, the ministry said.

The satellite communications were believed to have failed because of bad weather, said a source in the defence ministry who was not authorised to speak publicly.

Argentine submarine goes missing with 44 crew on board

It was not immediately clear what type of calls the vessel may have tried to make, but submarines that are stricken underwater can float a location beacon – known as an EPIRB – to the surface, which then emits emergency signals via satellite.

The last confirmed location of the German-built ARA San Juan was 432km off Argentina’s southern Atlantic coast early on Wednesday.

The US Navy said it was deploying a deep-sea rescue mission to Argentina from California to support the effort, with a remotely operated vehicle and two vessels capable of rescuing people from bottomed submarines set to arrive in coming days.

As nations from Chile to South Africa offered help, Argentine sea vessels and planes scoured the southern sea. But a storm with powerful winds and six-metre-high waves in the South Atlantic hindered the international search for the submarine. The weather disrupted visibility and movement in the area, navy spokesman Enrique Balbi said.

The submarine’s colour and design, which aim to camouflage the vessel in the ocean’s surface, also posed a challenge.

“The idea is to continue through the night and the early morning, depending on weather conditions,” Balbi said. The weather was expected to be somewhat improved on Sunday, he said.

A search of 80 per cent of the area that was initially targeted for the operation turned up no sign of the vessel, but the crew should have ample supplies of food and oxygen, Balbi added.

The dramatic search has captivated the nation of 44 million, which recently mourned the loss of five citizens killed when a truck driver ploughed through a bicycle path in New York City.

In the resort and fishing city of Mar del Plata, where the submarine had been destined to arrive before vanishing, a church service was held in honour of the crew members.

Many relatives of the crew members awaited news at the city’s naval base.

“We’re hopeful this will end soon to remain only as a bad memory,” said Maria Morales, mother of crew member Luis Esteban Garcia.

Messages of support poured in from around the world. Pope Francis, an Argentine, was praying “fervently” for the crew to return home soon, his office said.

The Argentine navy said an electrical outage on the diesel-electric-propelled vessel might have downed its communications. Protocol calls for submarines to surface if communication is lost.

The episode could hold political implications for President Mauricio Macri. His centre-right government has set an ambitious target for cutting government spending and said in March it had few funds available to replace an outdated military fleet beyond buying aircraft for training pilots.

The ARA San Juan was inaugurated in 1983, making it the newest of the three submarines in the navy’s fleet.

Built in Germany by Nordseewerke, it underwent mid-life maintenance in 2008 in Argentina, which required cutting its hull in half and sealing back it together again, according to state news agency Telam.

Nordseewerke now belongs to German industrial group Thyssenkrupp AG, which could not be reached for comment outside regular business hours.

Carlos Zavalla, a navy commander, urged loved ones of crew members not to give up hope.

“So far, the only concrete thing is the lack of communication,” Zavalla said on local television. “That’s all.”
