The military submarine KRI Nanggala-402, who had disappeared with 53 people on board last Wednesday (21), was found sectioned in three parts on the seabed off the coast of Bali, Indonesia. 

The information was released on Sunday (25) by the Chief of Staff of the navy of the country, Yudo Margono. The commander of the Indonesian Armed Forces, Hadi Tjahjanto, confirmed that "all 53 crew members died".

An underwater rescue vehicle provided by Singapore was used to obtain visual confirmation after Indonesian authorities received signals from the wreck site - more than 2.600 feet (800 meters) deep - early on Sunday (25).

In addition to the three parts of the vessel, an anchor and safety clothing used by the crew were found.

The cause of the military submarine incident is not yet officially known. Officials believe a major electrical malfunction has prevented the crew from returning to the surface.

The investigation also detected an oil slick in the area where the vessel sank, suggesting the rupture of the fuel tank.

Searches came to an end on Saturday (24)

The Indonesian Navy announced on Saturday morning (24) that the submarine's wreckage had been found and that there was no hope of finding survivors.

"According to our discoveries and the elements that come from the 'KRI Nanggala', we changed the situation of the submarine from missing to 'sunken'", declared Yudo Margono at a press conference.

During the press conference, the admiral went on to detail that the submarine must have gradually cracked, as it was sinking. This process would have happened when he was at a depth of 300 to 500 meters.

KRI Nanggala-402 lost contact with the Indonesian Navy on Wednesday (21), during military exercises in the north of the island of Bali. His disappearance happened shortly after the submarine was authorized to submerge.

Rescuers had previously warned that the crew's oxygen reserves could run out at 15pm on Friday, in GMT + 7 (Saturday morning according to Brasília time).
