What they find instead seems to be evidence of the worst-case scenario. The search and rescue team found items such as prayer rugs, grease bottles, parts of cooling pipes, and torpedo components believed to be from submarines... These items are only in the water if the submarine falls apart.

According to the Indonesian Navy, the wreckage is evidence of the submarine’s sinking, along with an oil slick that was found early in the search near the submarine’s last submarine, a sign of a fuel tank rupture.

Indonesian Navy Secretary of the Navy Margono said at a press conference on Saturday that “genuine evidence, believed to be from submarines, has moved from a” sub-miss “stage to a” sub-sinking “stage.” All passengers are estimated to be dead, AP reported..

According to Indonesian troops, the submarine had only about 72 hours of air at this point, which could be oxygen deficient.

The Indonesian Navy said it believed it was a 1,400-ton submarine manufactured by Germany in the late 1970s and refitted in 2012. It could have sunk to a depth of more than 2,000 feet, well beyond the point at which the hull could withstand the crushing pressure of the surrounding water...

“If a small diesel submarine like this Indonesia were submerged in 2000 feet of water, it wouldn’t survive,” said Bryan Clark, a former U.S. Navy submarine officer and current defense expert at the Hudson Institute. I told the insider.

It’s not yet clear what happened to the submarine, as KRI Nanggala 402 hasn’t been discovered yet, but if all 53 passengers sank, this horrific tragedy would be one of the worst submarine disasters. I will.
