The Indonesian navy lost contact with the 42-year-old German-builtvessel at 3am on Wednesday local time[6am AEST] after it set off on a dive while taking part in a training exercise.

The Indian navy also announced it was sending a search and rescue vessel,while the US sent a P-8 Poseidon surveillance aircraft to the search zone.
Officials said the submarine has a maximum operating depth of 500 metres but believed it may have sunk 600 to 700 metres. AP quoted an official from South Korea’s Daewoo Shipbuilding saying it would collapse if at a depth beyond 200 metres.
There is also only enough oxygen to keep the 53 submariners on board the vessel alive until Saturday,the Indonesian navy has warned. Submarine rescue vessels dispatched by the Singaporean and Malaysian navies are not due to arrive until Saturday and Monday respectively.
