Thank you for posting this, Jack. I find it astonishing that the submarine Skipper proceeded "on course" eastward away from port over deepening ocean only 7 hours after reporting salt water incursion through the submarine's snorkel, short circuiting of a battery system and fire on board his boat. There must be additional communication from HQ that's not been released. Sad story all around.

"Searchers know that just after midnight on November 15, 2017, San Juan’s captain alerted his Argentine Navy superiors via a satellite phone call that salt water had poured into the sub through its snorkel, which is used to bring fresh air to the sub when submerged.

“Seawater leaked in through the ventilation system into battery system No. 3, causing a short circuit and the early stages of a fire where the batteries were. The batteries on the external bow are out of service. We are currently submerging with a divided circuit. Nothing new to report regarding personnel. Will keep you informed,” according to a CNN English translation of the message, which was broadcast by Argentinian channel A24.

At 6 a.m. the captain sent a typed message repeating his satellite phone message, per Argentine Navy procedure. At 7:30 a.m. the sub sent a message stating it was proceeding on course. That was the final message received.

At 10:31 a.m., an undersea explosion was registered by an anti-nuclear proliferation listening station...….."

Sunken wreck of Argentine submarine that exploded and disappeared with 44 crew in the Atlantic is discovered 2,600ft down by US search

The wreck of an Argentine submarine that exploded and disappeared has been found almost exactly a year after it went missing.

The ARA San Juan submarine was located in the Atlantic Ocean on Friday, said the navy, crushing the last hopes for relatives of the 44 crew.

There has been 'positive identification of the ARA San Juan,' at a depth of 2,600 feet, a statement on Twitter from the navy said.

The Seabed Constructor, a vessel owned by US search firm Ocean Infinity, which set out in September on the latest attempt to find the San Juan, made the discovery.

The navy lost contact with the submarine on November 15 last year, about 280 miles from the Argentine coast.

It was on its way back to base from Ushuaia at the southern tip of Argentina.

The families of the 44 crew members who perished in the accident have been summoned to be officially informed.

Luis Niz, the father of one of the missing sailors said: 'I still had hopes that they could be alive.'

Yolanda Mendiola, the mother of crewman Leandro Cisneros, 28, said: 'We are with the other relatives. They are going to show us the photos. They say that our youngsters are inside.

'We are all destroyed here.'

Navy spokesman, Rodolfo Ramallo, told Todo Noticias TV that the Ocean Infinity ship 'decided to do a new search and, thanks to God, it was able to find the zone.

'Now another chapter opens. From the analysis of the state in which the submarine has been found, we will see how to proceed.'

The navy has been fiercely criticized for its handling of the operation since first reporting the submarine overdue at Mar del Plata on November 16, 2017.

It was only several days into the tragedy that navy officials acknowledged the old, German-built submarine had reported a problem with its batteries in its final communication of November 15.

Nearly 10 days later, the navy confirmed there had been an explosion on board, which experts said was likely linked to the battery problem.

An air and sea search involved units from 13 countries but the majority withdrew before the end of 2017, as the wintry South Atlantic refused to give up its secrets.

The Seabed Constructor is equipped with cameras that can be submerged to a depth of 6,000 meters. It was to receive a reward of $7.5 million if it found the missing sub.

Before it departed for its mission, Luis Tagliapietra, whose son Alejandro was a lieutenant on the San Juan, described it as 'the last opportunity to find them.'

Ocean Infinity was also assigned the task of searching for the Malaysia Airlines flight MH370 which vanished without trace in March 2014 en route from Kuala Lumpur to Beijing.
