President Joko Widodo has called on all Indonesians to pray for the return of the crew, and ordered every effort to be made to locate the ship in distress. Two ships left a port in a nearby area on the morning of April 23 to engage in search activity. More than 20 naval ships, 2 submarines and 5 aircraft were mobilized for search on April 22, and more large-scale search operations are expected on April 23. Lifeboats from Singapore and Malaysia are expected to be in the area from Saturday to Monday next week, and other countries have also requested assistance. In his televised speech on April 22, Mr. Widodo said: “Our main priority is the safety of the 53 crew members. To the families of the crew members, I can understand their feelings at the moment and we are doing our best to save the lives of all crew members on board. The country’s Navy Admiral Yudo Margono said the missing submarine is expected to run out of oxygen at about 3 a.m. on April 24. The search has been centered around the oil slick discovered near the submarine’s last dive site. But there is no convincing evidence that this oil streak belonged to the missing submarine. Admiral Margono said that the oil could be spilled from a crack in the submarine’s fuel tank or it could also be that the crew drained the oil and the fluids to reduce weight, allowing the ship to float. There was an unidentified object with high magnetism at a depth of 50 to 100 meters, and officials hope it was the submarine they were looking for, Margono said. The Indonesian Navy also believes that the submarine has sunk to a depth of 600-700 meters, much deeper than the landmark where the hull can withstand water pressure. According to estimates by a Korean company that repaired this submarine in the period 2009-2012, the ship could explode when it sank to a depth of 200 meters. Currently, people are still not sure about the reason why the submarine suddenly disappeared. The Indonesian navy said it was possible that an electrical incident could have prevented the submarine from performing emergency procedures to emerge. In addition to the lifeboats sent by Singapore and Malaysia, other offers of assistance have also come from Australia, the US, Germany, France, Russia, India, Turkey and South Korea.

In 2000, the Russian nuclear submarine Kursk exploded from the inside and sank during exercises in the Barents Sea. Most of the 118 crew members died immediately, while 23, although they managed to reach the rear compartment, were suffocated. In November 2017, an Argentine submarine went missing and 44 waterways in the South Atlantic, until nearly a year later, it was discovered that the wreck was 800 meters deep. But in 2005, seven members on a Russian mini submarine were rescued three days after their ship was caught in fishing nets and cables in the Pacific, at a time when the ship had only enough oxygen for six hours. if the lake cannot float to the surface of the water. It is known that the KRI Nanggala 402 submarine is currently missing, produced by Germany, has been used by Indonesia since 1981 and at the time of the accident carrying 49 sailors and 3 gunners and commanders.
