Indonesian Navy submarine goes missing with 53 sailors on board amid fears it sank to the bottom of a 2,300ft trough during military exercises off Bali

An Indonesian Navy submarine with 53 people on board has gone missing amid fears it sank during a military exercise off the waters of Bali.

The navy has deployed a number of warships to search for the missing crew and officials fear the vessel sank to the bottom of a trough with a depth of 2,300ft, reports Kompas.  

The German-made submarine, KRI Nanggala-402, was conducting a torpedo drill in waters north of the island of Bali on Wednesday but failed to relay the results as expected, a navy spokesman said.

The navy is now seeking help from Australia and Singapore, the country’s military chief said. 

Representatives of the defence departments of Australia and Singapore did not immediately respond to requests for comment.
