For the first two days after its disappearance the submarine was considered missing, but after Saturday it is likely the Type 209/1300 Cakra-class Diesel-Electric Submarine ran out of oxygen. An oil slick and debris (though no bodies) were found in the area by search parties. Over twenty ships from four different countries (Indonesia, Australia, Singapore & Malaysia etc) as well as Indonesian aircraft and a US Navy P-8 Poseidon will have joined the search by today.

Originally it was believed the submarine had sunk in waters two hundred meters deep, beyond the submarines collapse depth but earlier today, sonar scans seemed to indicate the submarine had actually sunk to a depth of 850 meters, well beyond the submarines presumed crush depth.

The KRI Nanggala had been in service with the Indonesian Navy since 1981.

Damn. Do they have an official cause yet? Battery failure?

Investigators and other researchers are exploring whether a giant 'underwater' (or internal) wave pulled the submarine into greater depths.

Called an oceanic nonlinear internal solitary wave, NASA says the phenomenon is known to happen about every two weeks in the Lombok Strait, where the sub was operating.

"Once the water carried the sub and pushed it down, what else could we have done? No safety measures could have tackled that problem," Indonesian Navy Rear Admiral Iwan Isnurwanto said, according to the Australian Broadcasting Corporation.

Furthermore investigators state satellite data seems to indicate such underwater waves, known as 'oceanic nonlinear internal solitary waves' were apparently active in the general area.

Could it be the same thing that sank the Argentine sub ARA San Juan as well?

Could it be the same thing that sank the Argentine sub ARA San Juan as well?

San Juan suffered a malfunction that forced it to surface in a rather rough weather and was either on the surface or shallow dive when something happened, while internal waves happen at greater depths.
