Missing Indonesian Submarine: US Joins The Search's Final Push

Missing Indonesian Submarine: US Joins The Search's Final Push

Three transport aircraft of the Indian Air Force (IAF) will transport submarine rescue equipment to Indonesia on Saturday to help the country trace an attack submarine that went missing with 53 people on board, officials said.

"With authentic evidence we found believe to be from the submarine, we have now moved from the "sub miss" phase to 'sub sunk, '" Margono said at a press conference in Bali, where the found items were displayed.

The navy's chief said a search party had recovered fragments from the KRI Nanggala 402 including items from inside the vessel, whose oxygen reserves were already believed to have run out.

The submarine - one of five in Indonesia's fleet - disappeared early Wednesday during live torpedo training exercises off the Indonesian holiday island.

Experts like Koh say Indonesia will have to expand the area of search again if the magnetic anomaly is proven not to be the vessel and warn that if the submarine is lost at an "extreme depth", it might not be possible to retrieve.

The navy said the submarine would have enough oxygen to last about 72 hours, meaning supplies could run out at around 3 a.m. on Saturday, local time.

Australian Navy ship HMAS Ballarat sails as it joins the search for Indonesian submarine KRI Nanggala.

Indonesian President Joko Widodo cancelled a visit to Banyuwangi port, where some rescue ships left earlier, to prepare for a weekend regional summit in Jakarta, officials said.

Even if the submarine were to be located, rescuing the vessel and its crew will be challenging, Frank Owen, director of the Submarine Institute of Australia, told NBC News.

The joining an global search for a missing Indonesian submarine that lost contact with its base earlier this week.

Singapore and Malaysia, as well as the United States and Australia, were among nations helping in the hunt with almost two dozen ships deployed to scour a search zone covering about 10 square nautical miles (34 square kilometres). He had said Indonesia's hydrographic vessel was still unable to detect an unidentified object exhibiting high magnetism that was earlier detected located at a depth of 50 to 100 meters (165 to 330 feet).

The search focused on an area near the starting position of its last dive where an oil slick was found but there is no conclusive evidence so far the oil slick was from the sub.

The navy has said a blackout may have occurred during static diving, causing a loss of control and preventing emergency procedures from being carried out.

Not only is that depth beyond the maximum depth of the submarine, potentially putting it at risk of a catastrophic hull collapse, but it also possibly puts it out of reach of available recovery options.

Submarine accidents are often disastrous.

Most of its crew died instantly but some survived for several days before suffocating.

Indonesia, the world's largest archipelago nation with more than 17,000 islands, has faced growing challenges to its maritime claims in recent years, including numerous incidents involving Chinese vessels near the Natuna islands.
