Time running out for missing Indonesian submarine as U.S. joins search

Rescue teams from several countries were battling against time on Friday to find a missing Indonesian Navy submarine lost in the Bali Sea with 53 crew, which would be rapidly running out of oxygen if not already crushed by water pressure.

Search helicopters and more navy ships left Bali and a naval base in Java at first light heading to the area where contact was lost with the 44-year-old KRI Nanggala-402 on Wednesday as it prepared to conduct a torpedo drill.

“The main priority is the safety of the 53 crew members,” President Joko Widodo said late on Thursday.

Indonesia’s navy said it was investigating whether the submarine lost power during a dive and could not carry out emergency procedures as it descended to a depth of 600-700 metres, well beyond its survivable limits.

An object with “high magnetic force” had been spotted “floating” at a depth of 50-100 metres, Indonesian Navy Chief of Staff Yudo Margono said, and an aerial search had earlier spotted an oil spill near the submarine’s last location.

If the submarine was still intact, officials said it would only have enough air to last about another 15 hours until early Saturday morning.

The diesel-electric powered submarine could withstand a depth of up to 500 metres (1,640 ft) but anything more could be fatal, Navy spokesman Julius Widjojono said. The Bali Sea can reach depths of more than 1,500 metres.

One of the people on board the boat was the commander of the Indonesian submarine fleet, Harry Setiawan.
