It's a dangerous job, even in peacetime.

[Jeff-Groves]

There is no safe job now days.
Ask the victims of rouge shooters!
Or maybe victims of people texting while driving or drunk drivers.
I actually fear the latter before the former more!
If you think your safe at a work from home job? Think again!
My home was invaded once. Now I'd see a massive slaughter should anyone be dumb enough to try it again.

They found it, at 2800 ft. A speaker said the boat has broken up into three pieces.


Detonation?

Perhaps but not terrorisme Kursk stile they were training firing live torpedo I guess something went terrible wrong before firing during the firing exercise or right after.

This is nothing but guesses-I'll await the official report.

It could very well be like that, mapuc. Some days ago media reported the sub was on a drill, and during that excercise it participated in asked for permission to go deeper than where it was expected to "attack" from. It then was allowed, went deeper, and then "something" happened.



My speculation: maybe they tried to fire a life torpedo from too deep, and the torpedo launcher's hatch door broke from the pressure.

In some report that I have read on the media it mentions that the last communication was the permision to load the torpedo tube. So one can guess that one possibility could be a malfunction that flooded the forward torpedo room when they opened breech door.
Just guessing but it could also happened in a very different way.
Hopefully they will investigate and the cause would be identified.
Rest in Peace.

My guess:

They asked for permission to go deeper, and I think they went too deep. Then:

- either the depth was what brought them into trouble and collected damage quickly until they broke, or (maybe more likely because of their request to load the tube)

- they asked for permission to load the torpedo tube, the inner tube door sealed or sealed not correctly, the outer one went open and the too big pressure due too excessive depth "entered" the boat via cracking open the inner torpedo tube doors.

Something like this.

Hopefully the truth/reason will come out sooner rather than later.

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.
