The part of the submarine that has flooded is dragging the boat down.
The survivors have closed watertight doors and are in their own subdivision. Electricity may go out and you're in pitch black. Assuming that minor things like tables and chairs and stuff aren't crashing around. In general it is said that when a ship is sinking you hear a succession of noises as bulkheads collapse. So a submarine that has 4-5 watertight compartments wont have them all get crushed at once. What may be horrific is the massive sound of, say, the engine room imploding, on the other side of your bulkhead, and knowing you're next. |

A couple people said it earlier. Actual implosion happens so fast you never even know or feel it. Well, you would probably know what's about to happen, but not when it did.
The diesel engine analogy is pretty good. |

If you hit crush depth, it's very, very fast. If, like on the Kursk, you basically spring a leak and sink to a depth the hull can handle, then it's pretty fucking rough. The visual that always fucked with me was that the Kursk was under less than a boatlength of water.

Quote HistoryQuoted: Didn’t implode, sank and ran out of oxygen Wiki-- "Following salvage operations, analysts concluded that 23 sailors in the sixth through ninth compartments reached refuge in the small ninth compartment and survived for more than six hours. As oxygen ran low, crew members attempted to replace a potassium superoxide chemical oxygen cartridge, which accidentally fell into the oily sea water and exploded on contact. The resulting fire killed several crew members and triggered a flash fire that consumed the remaining oxygen, suffocating the remaining survivors." Truth was there was no atmosphere in the kurst by the time the russians asked for assistance. Fire or no, they would have been dead. Theres also a good movie on the disaster as well. |

Then their eardrums would have burst and blood would have trickled from their noses and mouths, which was how they were found in the spacecraft. And it would have taken as long as a minute for them to lose consciousness completely, though they wouldn’t be active; they would be immobilized but aware. |

Quote HistoryQuoted: The only thing that would concern me about death, even an instantaneous one, is that the electrical impulses in the brain are near speed-of-light, so the malfunctions caused by death would feel like eternity to many. Don't worry about it - your brain does not operate electrically - it operates chemically, and nerve impulses travel at up to 120 m/s. You likely wouldn't have time to even notice that the hull was imploding. |

I can't imagine the horror of being in a sinking sub, knowing crush depth is coming and working feverishly to try to halt the boat's descent.
The end would be mercifully quick though. Plenty of our submariners have died that way, especially in WW2.

I doubt it would be instantaneous like the tanker crush. The hull would have to be remarkably homogeneous for that to happen. I would expect it to spring leaks, when that happens the internal pressure will equalize with the external. Depending on depths the water coming through would have the cutting power of a light saber. You would not feel the pressure in most parts of your body, human beings being mostly made of incompressible water. Your ears however, would behave like the tanker and immediately implode. Then you drown.

From an article I read the actual implosion takes ~40mS to occur (.04 seconds), well below the ability of a person to perceive the event. The sailors in that sub knew they were going down but likely weren't aware of the implosion event itself.
The pressure differential would be about 1100psi between inside and outside the hull and when the water did come in it would be moving at close to 1800 mph. |

I freedive/spearfish, and even at depths of 50-60' I can tell you that the effects of the pressure are noticeable, and oppressive.
Even with a really full breath, once I get down there my lungs feel completely flat and empty. The wetsuit is squeezing the shit out of your entire body. Took me a while to become at ease with it. You'd never feel this with scuba gear where you are re-expanding your chest cavity with new air. |

Quote HistoryQuoted: People don't think 15psi be like it is, but it do. Plenty of crooked milk silos and beer fermenters out there too. People are used to regular pressure gauges, they read zero when an absolute gauge would be reading 14.7 at sea level. Working in process you better fully understand what type of gauge you are looking at and how to apply the pressure reading. For some reason it took a lot of training with some operators to grasp that concept. |

Quote HistoryQuoted: And that was 1 atmosphere (14.7 psi") How many atmospheres at 800m? 1165 psi. 44ish PSI/100ft adds up fast. That's why the Kursk was "fine" sitting on the bottom waiting for rescue, since it was well within its normal operating depth. These guys were probably long gone before it rested on the bottom. Crush depth was considerably less than the depth of the bottom where they were operating. Like we discussed in the other thread for the missing boat, most of the worlds oceans are much deeper than crush depths outside of research or special purpose submarines. Hopefully it was quick for them. |

Depends how quick the submarine sank beyond its pressurized abilities.
If it sank slowly, the pressure would build slowly and I'd Imagine an excruciating way to die. If it sank fast? The hull would probably blow killing every one quickly. |

Its tough for the families because they think they are going to get a body recovered so they can morn and conduct whatever type of burial process they believe in.
That ship that sank near the Bahamas in a hurricane a few years ago capsized and sank so that crew drowned. It settled on the floor at 15,000 feet. Pressure at the level is around 6,500 psi. I cant imagine what a human body would look like under that pressure, guess you would be the size of a basketball or smaller. |
