On December 1st, 2017, confirmation of the detection and localization capability of the IMS network was made possible by a calibration test involving a depth charge deployed by the Argentine Navy. Two of the IMS hydrophone stations, HA10 in the central Atlantic Ocean and HA04 in the southern Indian Ocean, were found to have recorded an unusual hydroacoustic signal of unknown nature (a “hydroacoustic anomaly”), which originated from the vicinity of the last known location of the ARA San Juan. In the days following the initiation of the multi-national search and rescue mission, the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) analysed data recorded by its International Monitoring System (IMS) sensor network for any signals that could support this effort. CNN’s Alejandra Morales and Max Ramsey contributed to this report.The Argentine submarine ARA (Armada de la República Argentina) San Juan went missing on November 15th, 2017, with its last confirmed contact location around 600 kilometres East of Comodoro Rivadavia, Chubut, Argentina. Below that, it would buckle under pressure.ĬNN’s Daniel Silva Fernandez reported from Miami and Ignacio Grimaldi from Buenos Aires, while Laura Smith-Spark wrote from London. If intact after the explosion, the hull could have been expected to withstand ocean depths up to around 500 to 600 meters, he said. The sub was designed to have a shelf life of around 30 years, which had expired, he said. The ARA San Juan was an old diesel submarine, built in Germany in the mid-1980s but was refitted with new engines and batteries around five years before its disappearance, Peter Layton, a visiting fellow at the Griffith Asia Institute at Griffith University in Australia, told CNN last year. The vessel’s loss raised questions over the navy’s maintenance of its submarine fleet. “We would be pleased to assist with a recovery operation, but at the moment, we are focused on completing imaging of the debris field.” “Next steps are a matter for the authorities to determine,” Plunkett said. The company confirmed it has the ability to salvage remains of the submarine should the Argentines ask. Ocean Infinity told CNN on Saturday its search vessel is still conducting an analysis of the debris field found around the wreck. Oliver Plunkett, Ocean Infinity’s CEO, said in a statement he hoped the discovery of the submarine would lead to “questions being answered and lessons learned” that would prevent a similar incident in the future. Three Argentine navy officers and four family members of the crew of the ARA San Juan were invited on board as observers for the search mission, Ocean Infinity said. The same ship was previously involved in the search for missing Malaysia Airlines Flight 370. Ocean Infinity, a US company specializing in deep water search and recovery, began looking for the ARA San Juan in September, using autonomous underwater vehicles operated by a team on board its ship Seabed Constructor, the firm said. The vessel’s condition remains unclear.Īrgentina's first female submarine officer, Eliana Krawczyk, was among the crew of the ARA San Juan. l5k8p8Zjye- Armada Argentina November 16, 2018įootage showed relatives of the lost crew members grieving in the northern port of Mar del Plata, the submarine’s home base, as they received the news the submarine had been found.

An American company contracted by Argentina located the submarine. Hours before the wreckage was positively identified, the Argentine navy tweeted an image of a point of interest on the seabed, suggesting that a 60-meter-long object might be the missing vessel. Gabriel Attis later told reporters in Buenos Aires.įamily members at the navy headquarters were shown three images of the remains of the San Juan’s “sail,” or tower, and bow sections.
The wreckage of the ARA San Juan, which “suffered an implosion,” was found about 870 meters (2,850 feet) down on the ocean floor, Argentine naval Capt. A missing Argentine naval submarine has been found, a year and a day after it vanished in the South Atlantic with 44 crew members on board, authorities said Saturday.
