Argentina's navy confirmed Thursday that an unusual noise heard in the Atlantic near the last known position of a missing submarine appeared to be an explosion, dashing the last hopes of finding the vessel's 44 crew members alive.
Relatives of the missing sailors reacted with grief and anger to the news after holding out hope since the sub was reported overdue at its Mar del Plata base on November 17, two days after the explosion.
"An anomalous, singular, short, violent and non-nuclear event consistent with an explosion," occurred shortly after the submarine's last communication, navy spokesman Captain Enrique Balbi told a news conference in Buenos Aires.
After days of false hopes, some of the relatives said the navy had withheld information about the sub and lied to them over the past week.
"I feel cheated," said Itati Leguizamon, whose husband German Suarez was a sonar operator on the ARA San Juan.
"They did not tell us they died. But they tell us they are three thousand meters (9,800 feet) deep," added Leguizamon as other family members shouted angrily around her.
"They lied to us," said Leguizamon, a lawyer.
A sobbing Jessica Gopar, whose husband was an electrician aboard the San Juan, said "they just told us that the submarine exploded."
She spoke as she came out from the sub's base.
"He was the love of my life, engaged seven years before we got married," Gopar said of her husband, Fernando Santilli. "And how can I tell my son that he no longer has a father?"
Underwater sounds detected in the first days of the search by two Argentine search ships were determined to originate from a sea creature, not the vessel. Satellite signals were also determined to be false alarms.
The San Juan, a 34-year-old German-built diesel-electric submarine, had reported a battery problem on November 15 and said it was diverting to Mar del Plata, but did not send a distress signal, according to the navy.
Balbi admitted on Wednesday that the situation for the sub and its crew appeared to be worsening.
However, he refused to speculate at that point on the origin of what he initially described as a "hydro-acoustic anomaly" detected in the ocean almost three hours after the sub's communication and 30 miles (50 kilometers) north of its last known position.
Balbi explained that information about the unusual noise only became available Wednesday after being relayed by the United States and "after all the information from all agencies reporting such hydro-acoustic events was reviewed."
Explaining the lack of debris on the surface, Balbi said "nothing will end up floating to the surface" because a submarine "implodes".
Gustavo Mauvecin, director of the Center for Hyperbaric Medicine at Mar del Plata, said hydrogen "is always an issue with submarines with electric engines".
The San Juan "has 500 tons of lead-acid batteries, which release hydrogen if there is an overcharge in the battery. Hydrogen in contact with oxygen is explosive".
- An explosion 'so violent' -
"In my opinion, after an explosion like that, it's difficult for there to be survivors," a former submarine commander told AFP.
The newspaper La Nacion said one hypothesis is that there was a short circuit in the batteries. It said this would explain the sub's failure to communicate and the fact that it did not have time to send off a distress signal.
The commander said a problem with batteries, as the sub had reported, could in fact cause a blast.
"A severe problem with batteries might generate hydrogen. Hydrogen above a certain percentage is explosive," said the commander who requested anonymity.
Horacio Tobias, former chief of diving for the San Juan, said it "was so violent that they would not have had time to realize what happened".
The San Juan would have had enough oxygen for its crew to survive underwater in the South Atlantic for seven days since its last contact, according to officials. That time had elapsed by 0730 GMT Wednesday.
Argentina is leading an air-and-sea search to try to still find the sub. It is getting help from several countries now including Brazil, Britain, Chile, Colombia, France, Germany, Peru, Russia, the United States and Uruguay.
Russia was the latest navy to volunteer help, sending an oceanographic research ship as the operation shifted from rescue to recovery.
The Russian defense ministry said the Yantar was steaming to the area from the western coast of Africa on the orders of President Vladimir Putin.
The weeklong search has focused on the sub's last known position, around 200 miles off the Argentine coast, but has been hampered by bad weather.
Putin offered "words of support over the situation with the San Juan submarine" in a phone call to Argentine President Mauricio Macri late Wednesday, the Kremlin said.
Russia said the Yantar "is equipped with two deep water submersibles which allow exploratory searches at a depth of up to 6,000 meters."
US President Donald Trump offered his support, tweeting: "May God be with them and the people of Argentina!"
A snapshot of the Argentine sub's crew
- Woman weapons officer -
Lieutenant Eliana Maria Krawczyk, 35, is third-in-command of the sub. As chief weapons officer, she is responsible for the ship's arsenal of 22 torpedoes. She grew up in Misiones province, near the borders with Paraguay and Brazil, around 1,000 kilometers (600 miles) from the sea. She dreamed of becoming an engineer but enrolled at naval school after a double family tragedy - her brother's death in a car accident and her mother dying from a heart attack. She enrolled in the naval school instead, having her first encounter with the sea at 21. She specialized in under-sea warfare, becoming Latin America's first female submarine officer.
- San Juan commander -
Captain Pedro Martin Fernandez has been commander of the San Juan since 2015. Married with three adolescent children he flirted with the idea of becoming a teacher before joining the navy. In two decades of missions and training programs he has traveled the world. The 45-year-old lived for a decade in Mar del Plata, home port of the navy's two operational submarines, the San Juan and the Salta.
- Future couples -
Naval rating Luis Niz, 25, was due to marry soldier Alejandra Morales on December 7. He only joined the crew of the San Juan after getting a promotion in 2016.
Lieutenant Renzo Martin Silva, 32, has been in the navy since the age of 18. The submarine enthusiast grew up in the foothills of the Andes in the Argentine province of San Juan, for which the submarine was named.
He planned to marry his girlfriend, a soldier, Lieutenant Maria Eugenia Ulivarri Rodi, next year.
- New father Fernando -
Fernando Santilli, 35, became a submariner seven years ago. He left the wine-growing province of Mendoza to become an engineer. His wife, Jessica Gopar, posted a moving letter on Facebook on Tuesday, in which she said every day of waiting "is a little harder. There are moments of hope, others of great distress. You cannot imagine how many people are praying for you."
She dedicated a few lines of her note to the commander, asking him to "do the impossible and get back to the surface. You have 44 lives in your hands. I'm waiting for my love. See you soon."
- Father to be -
Rating Mario Armando Toconas Oriundo, 36, has spent 13 years in the navy. From Patagonia, he went to live in Mar del Plata, a seaside resort as well as the sub's home port. Father of an eight-year-old boy, his partner is four months pregnant with their second child.

Argentina's navy said Wednesday it was investigating an unusual noise detected in the South Atlantic hours after it last communicated with a missing submarine, but refused to confirm whether it indicated an explosion. The development came as the clock was ticking down on hopes of finding alive the 44 crew members now missing for a week despite a massive search of surface and seabed, amid fea ... read more
