An Argentinian submarine that went missing last year has been discovered in the bottom of the South Atlantic Ocean.

ARA San Juan (S-42) disappeared on November 15, 2017, with all 44 crew members. Almost to the day a year later, the Argentinian Navy is confident that it has found the wreckage. The missing sub appears to have settled more than 2,500 feet deep, 373 miles east of Comodoro Rivadavia, which is situated near the Argentine section of Patagonia.

The U.S. salvage and seabed survey company, Ocean Infinity, led the detection efforts. The discovery happened with a remotely operated submersible operated by the American ship Seabed Constructor. Using five Autonomous Underwater Vehicles (AUVs), and a team of more than 60 people — that included Argentine Navy officers, family members, and numerous specialists in underwater operations — Ocean Infinity managed to locate the wreckage within the sixty-days commitment that it had agreed upon.

In a statement, Oliver Plunkett, the CEO of Ocean Infinity, acknowledged the significant assistance that his team and the Argentinian Navy received from the international community.
