the submarine missing off Bali with 53 men on board was wrecked, the Navy confirmed on Saturday. Indonesia, and hopes of finding the crew alive, whose oxygen reserves would have been exhausted, are far away.

The navy found in the sea various wrecks of the submarine, some of the interior of the submersible, suggesting Irreparable damage.

Hundreds of soldiers and twenty ships have been mobilizing since Wednesday to locate the “KRI Nanggala 402”, a submersible forty years old of German construction.

The Navy estimated the maximum supply of oxygen available to crew members in the event of a power outage was 72 hours, a deadline that was met early in the morning on Saturday. Thus, it is unlikely that they could have survived.

“Based on what we believe is from ‘KRI Nanggala 402’, we changed the status of the submarine from ‘missing’ to ‘sunk’,” said Yudo Margono, Indonesian Navy spokesman. at a press conference.

The recovered remains “could not have gotten out of the submarine without outside pressure or damaging its torpedo launch system,” he said.

The Navy recovered several items, including a fragment of the torpedo system and a bottle of grease. used to lubricate the periscope of the submarine. He also found a prayer rug used by Muslims.

“No ship has passed within a ten mile radius, so experts believe these items belonged to KRI Nanggala,” Margono said.

The submarine, one of five belonging to the Indonesian navy, was submerged early Wednesday during planned military exercises in the north of the island of Bali. Contact with the submersible was lost shortly thereafter.

Doubts about the crew

The chances of finding the crew of the submarine alive were already minimal since the 72 hour deadline set when the limit of oxygen reserves was reached.

A power cut during the submersion, he was able to cause the sailors to lose control of the submersible and prevent them from carrying out an emergency evacuation, according to the Indonesian navy.

The Indonesian official clarified that the oxygen lasts a maximum of three days in the event of a power failure, but If the electrical systems continued to operate, it could take up to five days.

What happened?

Military authorities believe that the submersible it may have sunk to 700 meters, a depth much greater than that for which it was designed.

They gave no explanation as to what may have happened or why more occupants than expected in the context of the pandemic.

According to experts, an oil spill detected in the area where it sank raises concerns about a possible rupture of the field, or even a fracture of the submarine.

This fuel stain is a “bad sign”, said retired French vice-admiral Jean Louis Vichot, former commander of strategic nuclear submarines (SNLE).

“This diesel is contained in warehouses, outside as well as inside. If the hull breaks, the tanks break and the diesel rises to the surface,” he told AFP.

This type of submarine is designed to withstand pressure up to 300 or 400 meters deep. Your helmet may break under greater pressure, according to this expert.

According to the navy, the submarine, delivered to Indonesia in 1981, was in good working order.

International rescue aid

The Southeast Asian archipelago does not have the capacity for this type of rescue operation and has resorted to help from other countries.

The United States sent airborne troops and two Australian Navy ships arrived in the area. It is also expected to receive reinforcements from India and Malaysia, as well as an underwater rescue ship from Singapore, the MV Swift Rescue.

So far, Indonesia has not had any serious incidents related to submarines. But this incident brought back memories of other such tragedies.

One of the best-known was in 2000, when the Russian nuclear submarine “Kursk” sank while maneuvering in the Barents Sea with 118 crew on board.

One of the torpedoes exploded, destroying the entire ammunition depot. The 23 sailors died because they were not rescued in time.

The memory of the submarine of the Argentine fleet “ARA San Juan“, who disappeared in November 2017 with 44 crew members, has also been revived these days.
