Argentine submarine (44 aboard) goes missing

Those shades of blue indicate depth. As best I can tell (using the site I posted earlier) at the projected location when the explosion was heard, it was in a 4000 to 5000 meter deep region. So the whole sub is probably roughly the diameter of a soccer ball now.

Daily Mail (UK) is saying a US Navy may have located the missing sub:

No confirmation and sadly the problem they are quite probably at the end of their oxygen.

Could the submarine draw attention by deliberately firing torpedoes and setting them to detonate at a safe but nearby distance?

ISTM there’s a pretty narrow range of problems where you have enough spare electricity, compressed air, uninjured crewmen, and unflooded compartments available to spend some of that firing a torpedo but you don’t have enough of all that stuff to use it to help you surface.

I feel so much better about dying in a submarine. Fortunately, it isn’t likely to happen.

This is a recent update on the missing submarine ,it been on the news everyday here. I keep hoping to hear some good news . :frowning:

It’d be worth a try!

Doesn’t sound good. Excerpts:

Is that 0.1 seconds for the outer hull, or the entire submarine itself? Seems like the force would first smash in the outer hull, but then the rush of water would have to reach the inner bulkheads/compartments (which are probably themselves sealed off tightly,) and then smash those, and then smash what’s in there.

So instead of one “BANG”, it would be like “BANG-bang-bang-bang-bang”. Still a quick death, but maybe just long enough for the human brain to register “implosion.”

I think it’d be very quick. Those are tremendos pressures.

Have been reading Argentina news sites: there are stories of uncontained rage at the briefing. “They sent them out on a piece of s**t!” Some family members escorted out by Marines…

It would look like this

That is rather tacky. People may have died.

it’s not meant to be tacky, it’s meant to explain it would be an instantaneous, painless death.

Let us hope they are alive waiting rescue.

The sail doesn’t look particularly beaten up to me. Note that a submarine sail is typically constructed of welded plates of high-tensile alloy steel.

Apropos of nothing, I served on a U.S. submarine with the same name as the missing Argentinian sub, the USS San Juan (SSN-751). Interestingly, the U.S. Navy lost contact with this submarine back in 2007 to the extent that they had actually begun notifying the families of the 140 crew members that the sub was missing – but it turned out to be a case of miscommunication.

Unfortunately, it does not appear there will be such a happy resolution for the fate of the missing Argentinian sub. :frowning:

Larger example with a tank car.

Absolutely. The world needs a bit of good news.

Not looking good.

And that demonstration is only atmospheric pressure. Nothing compared to the tremendous, far greater water pressure of the sea.

I didn’t thnk it was tacky.
