Indonesia’s military on Sunday officially said all 53 crew members from a submarine that sank and broke apart last week are dead, and that search teams had located the vessel’s wreckage on the ocean floor. The grim announcement comes a day after Indonesia said the submarine was considered sunk, not merely missing, but did not explicitly say whether the crew was dead. Officials had also said the KRI Nanggala 402′s oxygen supply would have run out early Saturday, three days after the vessel went missing off the resort island of Bali. “We received underwater pictures that are confirmed as the parts of the submarine, including its rear vertical rudder, anchors, outer pressure body, embossed dive rudder and other ship parts,” military chief Hadi Tjahjanto told reporters in Bali on Sunday. “With this authentic evidence, we can declare that KRI Nanggala 402 has sunk and all the crew members are dead,” Tjahjanto said.

Yudo Margono, the navy’s chief of staff. That’s much deeper than the KRI Nanggala 402′s collapse depth of 200 meters (655 feet), at which point water pressure would be greater than the hull could withstand, according to earlier navy statements. Margono said emergency survival suits that are normally kept in boxes were found floating underwater, apparently indicated the crew may have tried to put them on during the emergency. The cause of the submarine’s sinking remains uncertain. The navy had previously said an electrical failure could have left the submarine unable to execute emergency procedures to resurface.

Photos of the debris were presented at the press conference. The underwater robot deployed by Singaporean vessel MV Swift Rescue provided the images, while the Indonesian vessel KRI Rigel had scanned the area where the submarine was believed to have sunk using multibeam sonar and a magnetometer, Tjahjanto said. Indonesia’s President Joko Widodo delivered his condolences in a televised address Sunday. “All Indonesians convey deep sorrow for this tragedy, especially to all of the families of the submarine’s crew. They are the best sons of the nation, patriots guarding the sovereignty of the country,” Widodo said.

The German-built diesel-powered KRI Nanggala 402 had been in service in Indonesia since 1981 and was carrying 49 crew members and three gunners as well as its commander, the Indonesian Defense Ministry said. Indonesia, the world’s largest archipelago nation with more than 17,000 islands, has faced growing challenges to its maritime claims in recent years, including numerous incidents involving Chinese vessels near the Natuna islands.

Indonesia’s navy on Saturday said items were found from a missing submarine, indicating the vessel with 53 crew members had sank and there was no hope of finding survivors. Navy Chief Yudo Margono said rescuers found several items from the KRI Nanggala 402, which disappeared after its last reported dive Wednesday off the resort island of Bali, including parts of a torpedo straightener, a grease bottle believed to be used to oil the periscope and prayer rugs. “With the authentic evidence we found believed to be from the submarine, we have now moved from the ‘sub miss’ phase to ‘sub sunk,’” Margono said at a press conference in Bali where the found items were displayed.

Indonesia had considered the submarine that disappeared Wednesday off the island of Bali as just missing. An American reconnaissance plane, a P-8 Poseidon, landed early Saturday and was set to join the search, along with 20 Indonesian ships, a sonar-equipped Australian warship and four Indonesian aircraft. Singaporean rescue ships were also expected later Saturday, while Malaysian rescue vessels were due to arrive Sunday, bolstering the underwater hunt, Indonesia military spokesperson Djawara Whimbo said earlier Saturday. He had said Indonesia’s hydrographic vessel was still unable to detect an unidentified object exhibiting high magnetism that was earlier detected located at a depth of 50 to 100 meters (165 to 330 feet). There had been no signs of life from the submarine, but family members held out hope that the massive search effort would find the vessel in time. “The family is in a good condition and keeps praying,” said Ratih Wardhani, the sister of 49-year-old crewman Wisnu Subiyantoro. “We are optimistic that the Nanggala can be rescued with all the crew.” Indonesian President Joko Widodo had ordered all-out efforts to locate the submarine and asked Indonesians to pray for the crew’s safe return. The search focused on an area near the starting position of its last dive where an oil slick was found but there was no conclusive evidence so far the oil slick was from the sub. Margono, the navy cheif, had said oil could have spilled from a crack in the submarine’s fuel tank or the crew could have released fuel and fluids to reduce the vessel’s weight so it could surface. The navy however, believes the submarine sank to a depth of 600-700 meters (2,000-2,300 feet), much deeper than its collapse depth of 200 meters (655 feet), at which water pressure would be greater than the hull could withstand.
