With the authentic evidence we found believed to be from the submarine, we have now moved from the 'sub miss' phase to 'sub sunk,' Adm. Margono said at the press conference, in which the found items were displayed.
The cause of the disappearance was still uncertain. The navy had previously said an electrical failure could have left the submarine unable to execute emergency procedures to resurface.
Margono said that in the past two days, searchers found parts of a torpedo straightener, a grease bottle believed to be used to oil the periscope, debris from prayer rugs and a broken piece from a coolant pipe that was refitted on the submarine in South Korea in 2012.
Margono said rescue teams from Indonesia and other countries will evaluate the findings, adding that no bodies have been found so far.
An American reconnaissance plane, a P-8 Poseidon, landed early Saturday and had been set to join the search, along with 20 Indonesian ships, a sonar-equipped Australian warship and four Indonesian aircraft.
