A missing Indonesian submarine has been found, broken into at least three parts, at the bottom of the Bali Sea, army and navy officials said on Sunday, as the president sent condolences to relatives of the 53 crew. Rescuers also found new objects, including a life vest, that they believe belong to those aboard the 44-year old KRI Nanggala-402, which lost contact last week as it prepared to conduct a torpedo drill. The German-built vessel was delivered in 1981, and she underwent an overhaul and modernization period at DSME in 2012. A sonar scan on Saturday detected the submarine at 850 metres (2,790 feet), far beyond the Nanggala’s diving range. The cause of the sinking is not yet known, but Indonesian officials have ruled out an explosion.
