Search helicopters and many other ships left Bali and a naval base in Java headed for the area out of contact with the KRI Nanggala-402 on April 21 as she prepared to conduct a torpedo exercise. . If the submarine was still intact, officials said it would only have enough air for the crew members to survive until around dawn April 24. “So far we have not found it … but with existing equipment we can find the location,” – Achmad Riad, a spokesman for the Indonesian army, said during a press conference. An Indonesian air force pilot said six tons of equipment had been moved to a base to help with the search, including an underwater hot air balloon to help lift the ship.

The Chief of Staff of the Indonesian Navy – Yudo Margono said an object with “high magnetic force” was found “floating” at a depth of 50-100 meters and an earlier aerial search had detected a trace. The oil spills near the location where the submarine last caught the signal. Navy spokesperson Julius Widjojono said the diesel-electric submarines can withstand depths of up to 500 meters but surpassing this threshold can kill people inside. The Bali Sea can reach a depth of more than 1,500 meters. One of the men on board was the commander of the Indonesian submarine fleet, Harry Setiawan. The submarine was commissioned into the Indonesian fleet in 1981 and underwent refitting in Korea, completed in 2012. It was said to be in good condition before meeting, the Defense Ministry said. accident. Australia, India, Malaysia, Singapore and the US have sent special ships or aircraft to respond to Indonesia’s request for assistance. The US military is sending a P-8 Poseidon to assist with the submarine search. The Pentagon said US Defense Secretary Lloyd Austin spoke with his Indonesian counterpart and offered additional assistance, which may include navigating underwater search equipment. Two Australian Navy ships are also heading to the search area including a frigate with special sonar scanning capabilities. Indonesia operates five submarines – 2 German-made Type 209s and three newer Korean ones.

Photo: USN Collin Koh, an expert at the Indonesian Institute for Strategic and Defense Studies, said that assuming a submarine has enough oxygen for 72 hours is an optimistic statement, as the submarine’s oxygen-generating capacity will be limited during power outages. . “So it’s possible that the oxygen has run out,” Koh said. Experts like Koh said Indonesia will have to expand the search area again if the highly magnetic object proves not to be a ship. Koh also warned that if the submarine falls to “extreme depth”, it will be almost impossible to find. The Bali Sea can reach a depth of more than 1,500 meters. At the time of his disappearance, there were 53 people on board. Including commander of Indonesian submarine fleet – Mr. Harry Setiawan. KRI Nanggala-402 submarine went missing on the morning of April 21 while participating in a torpedo drill near Bali island.
