DENPASAR: 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 on Wednesday as it prepared to conduct a torpedo drill. "Based on the evidence, it can be stated that the KRI Nanggala has sunk and all of its crew have died," military chief Marshal Hadi Tjahjanto told reporters. Navy chief of staff Yudo Margono said the crew were not to blame for the accident and that the submarine did not experience a blackout, blaming "forces of nature". "The KRI Nanggala is divided into three parts, the hull of the ship, the stern of the ship, and the main parts are all separated, with the main part found cracked," he said. "There are scattered parts of the submarine and its interior in the water."
