Indonesian submarine gone amiss

The boat is German-made (probably a type 209) and 43 years old. It underwent an overhaul in Germany end of the 80s, and a 2 year refit in South Korea ten years ago. Its one of five submarines Indonesia is operating.

Hopefully they will be found and in an area a rescue may be undertaken.

^There's not a chance of finding them alive and they'll be extremely lucky to find the sub in shallow water within a week or a month never mind that deeper water it reportedly disappeared in.

Looking at everything that is coming out I'm hearing the boat is down in 700 to 800m deep waters and well if she is down in one piece the only way she is making that depth is if she flooded first.

Personally and I know I sound like an ass in saying this but i hope the above is not the case and the boat was crushed simply because it would be quick and painless.

But I hope I am totally wrong on both counts

BBC isn't updating which isn't encouraging.

The boat went out with 56 men she normally carries 30-36 she has been down for now nearly 2 days

The air in that boat is going to be running out fast

obviously at 800 meters, they are past crush depth.

if it is in only 3 pieces, that could indicate, the sub flooded.

If it was not flooded or partly flooded, it would implode when past crush depth and you would see hundreds of pieces, like the wreckage from the USS Thresher.

If it was flooded, then it would not implode since the water presure inside and outside the sub would equalize, but could have fractured when it hit the ocean floor since it would have been going fairly fast at that point due to gravity.

again, just speculation at this point. You are talking about a very old sub, so we have no idea what shape it was in.

Not necessarily. It could have "telescoped" and failed at weld joints. If I recall the type 209s are single hulled and only have two main ballast tanks (as well as trim tanks).

Its kinda clickbaitish IMO because even the professor in the video thought it unlikely the wave could have been the sole cause. But it is interesting

While some speculated that the submarine was hit by a foreign missile or a power blackout, Indonesian authorities now suspect the submarine was pulled under by a powerful underwater current called an internal solitary wave.

I posted this over at the cruiser's forum. Just thought y'all might find it interesting, too.
