- - WOw EXTREME DEPTH!!!!! VIIC (https://www.subsim.com/radioroom/showthread.php?t=92602)

Here is the story of a US WW2 fleet sub which went down to 1,000 feet and survived.

http://www.geocities.com/jaob/deepdive.htm

The Hull was so damaged by the pressure that the sub was taken out of service. As a Balao class, it had a test depth of 400 feet.

And this is the result of a really deep dive, USS Thresher which during a deep dive in 1963, sank below crush depth and imploded from the pressure.

I'm guessing some of that is at least possible if not wholely probable in such an event as a submarine implosion... yay discovery channel!

No. Just a big bubble :D The only heat would be that of the depthcharges.

Uhm, severe lung collapse,and one that is filled with water, presure equalizes and there nothing more to happen, untill the body gets sniffed out by a shark :-?

Cheers!

"The Thresherâ€™s hull gave way. Inrushing seawater spiked air pressure, quickly killing the crew. The pressure also ignited the subâ€™s diesel fuel, causing an explosion that tore the high-tech vessel to pieces."

Oh, they burn.

Glad you enjoyed it. No one really knows what happened on the Thresher other than what can be deduced from the one garbled message and the wreckage.

The official navy report presumed that a seawater pipe burst because of the pressure ( she was doing a "deep" dive, I think around 1,200 feet ) which would have knocked out power causing her to slowly sink below crush depth, but no one really knows.

The important point is that an implosion from sea pressure will disintegrate a sub, killing the crew instantly, as you can see from the photos.

The story of the Thresher is what first got me interested in submarines when I was a kid, so I have always had a special interest in her.

I think that 1 of the recorders was Soviet era class Mike(Komsomoletc if im right)which had titanium hull but i think her max depth was around 600-700m...She was lost in late 80s due to fire in electrical systems...she sank NW from Norvay with around 50 men....some was saved becose she surfaced but in cold water many perished before help was on scene....
