The German-built diesel-powered KRI Nanggala 402 has 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. The navy has said an electrical failure could have left the submarine unable to execute emergency procedures to resurface. The cause of the disappearance is still uncertain. 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.

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 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.

Indonesian President Joko Widodo had ordered all-out efforts to locate the submarine and asked Indonesians to pray for the crew’s safe return. “We are optimistic that the Nanggala can be rescued with all the crew." “The family is in a good condition and keeps praying," said Ratih Wardhani, the sister of 49-year-old crewman Wisnu Subiyantoro.

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.

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). 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. Indonesia had considered the submarine as just missing.Īn 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. Officials previously said the submarine’s oxygen supply would have run out early Saturday.
