Submarine Found Sunk A Year After Disappearing

The Argentinian Navy have said a submarine that went missing last year has been found deep in the Atlantic.

The ARA San Juan was detected more than 2,600 feet deep in waters off the Valdes Peninsula in Argentine Patagonia, a statement said.

The Navy said a "positive identification" has been made by a remote-operated submersible.

The submersible from the American ship, Ocean Infinity, was hired for the latest search for the missing vessel.

The discovery was announced just two days after families of the missing sailors held a commemoration one year after the sub disappeared on November 15, 2017.

On the anniversary of the disappearance, Argentina's president Mauricio Macri said the families of the submariners should not feel alone and delivered an "absolute and non-negotiable commitment" to find "the truth".

He promised a full investigation after the submarine was lost.

Federal police raided naval bases and other buildings last January as part of the probe, soon after the government dismissed the head of the navy.

The Submarine was returning to its base in the city of Mar del Plata when it was first realised that contact was lost.

The navy said previously the captain reported on November 15 that water had entered the snorkel and caused one of the sub's batteries to short-circuit. The captain later communicated that it had been contained.

Some hours later, an explosion was detected near the time and place where the San Juan was last heard from.

The navy said the blast could have been caused by a "concentration of hydrogen" triggered by the battery problem reported by the captain.
