Signals detected from Argentina's missing submarine

Distress calls bring hope to search for missing Argentina sub

Hunt on for missing Argentine submarine

"This is why we are deploying all resources with high-tech sensors". This system is used for deep-water rescues the SRC can't handle.

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

"Luckily we have been able to continue with the air search", Balbi told reporters on Sunday.

One Naval P-8 arrived in Argentina over the weekend, and another is arriving today. Thus far, rough weather and high seas have been hindering the search, and hopes for the missing crew are fading.

Argentina's navy says it's analysing the sounds detected on their sonar about 225 miles off the coast after the ARA San Juan vanished in the South Atlantic last Wednesday.

The sub's primary role has been intelligence collection, including surveillance of fishing grounds in Argentina's economic zone for illegal fishing operations.

The maritime search for the German-built diesel-electric vessel has also been made hard by stormy seas with waves up to 20 feet (6 meters). It also carries a powerful surface-scanning radar system, but the aircraft lacks the magnetic anomaly detection gear carried by its predecessor, the P-3 Orion.

The U.S. Navy said early on Sunday morning that it would send an aircraft with 21 personnel from Jacksonville, Florida, to assist with the search.

The search goes on for the missing Argentine submarine.

The calls revived hopes that the submarine has surfaced, but a powerful storm that has whipped up waves reaching seven meters (23 feet) in height has made geolocation hard, officials said.

He said the attempt to use a satellite phone indicates that "the submarine had to emerge to a depth that allowed the call".

The diesel-electric ARA San Juan was returning to its base south of Buenos Aires after a routine mission to Ushuaia, near the southern tip of South America, on Wednesday. The sub would have oxygen for 10 days when submerged even without power.

Claudio Rodriguez, whose brother Hernan is aboard the submarine, was hopeful, saying the satellite signals suggested the vessel was still afloat and would be found.
