I mean, I'd rather shoot myself than being crushed to death

Crush deaths in submarines are either near instant or completely instant, so it's not really a big deal
How come fish are not crushed below a certain depth?
Because deep sea fish have the same pressure in their bodies as with the outside pressure. The down side is their metabolic rates are much slower then ours to compensate for the pressure. They essentially have no cavities or voids to be crushed.
They're 'crushed', but only gas is problematic at high pressure. They don't breath air/have air (swim bladder) so pressure isn't a problem as big as to humans. Of course all abyss fish would die if they're raised too quickly because of dissolved gases in their fluids. Or something like that iirc.
>Of course all abyss fish would die if they're raised too quickly
This is what the blobfish is supposed to look like. It only turns into the pink blob when it's brought to the surface where it pretty much just melts.
He looks like he's got really bad five o'clock shadow
>Only gas is problematic at high pressure
You are retarded, but it's ok.
Gases are compressible, ASAT.
>yeah, it isn't only because of that but whatever
You get some fun stuff happening to natural biological processes as you get beyond certain depths.
They can still swim down bellow that depth and survive it's just they cannot maintain their metabolism and energy at that depth.
There's enough energy down there, it's not that.
Well, yeah, there're a lot of reasons beyond the simple "get crushed". Neurochemistry also is affected even by inert (heavy) gases (mainly nitrogen) way before than 8km underwater.
Better article, more in depth, Kek.
>more in depth
That one really was tight, stealing it to work into conversations.
Because they can swim, duh!
those fish have evolved to live at those depths, they cant live at surface level - that blob fish people love to post has expanded because of the different pressure
They have the reverse problem
Holy shit, Total Recall was real!
Equalized pressure due to being filled with water
The time spent leading up to that can be torturous, it doesn't necessarily go all at once instantaneously or the sub is stranded at some intermediate depth inconvenient for search and rescue with compromised hull/engine whatever. The catastrophic failure would be a mercy if in every case it came the moment the sub became unrecoverable and beyond rescue submersible range.
How much does each individual sailor know about the sub's depth? Are there depth gauges in every compartment? Do they broadcast each 100 foot/meter drop over the intercom? Or do the nukes just have to slowly worry about why everything is starting to creak more and more?
Depending on the class it's not in every space though it's fairly common knowledge amongst the crew how deep you are. Depending on what the ships doing the information is passed about more nonchalantly than the weather
In all aviation/maritime circles, you fight to the END. In all militaries abandoning your aircraft or ordering an abandon ship when you are not facing imminent doom would get you court martialed and places in military jail for decades. It can be torturous, and imo crimson tide shows this really well, but war is torturous.

>Crush deaths in submarines are either near instant or completely instant, so it's not really a big deal
Somehow I doubt that.
At the pressure required for metal to fail, your body is gonna get shoved into Davy Jones's locker, a 3 inch cube, faster then your brain will process it. The only problem would be the terror as you slowly approach those depths and know you're going to certainly die.
If your pressurized steel hull can't hold the water back, your fragile meatbag won't either. The second the water comes in, you're a heartbeat from the ol' Pearly Gates
>crushed to death
If the hull fails because of depth then don't worry, you're turn into paste in milliseconds.
You actually get cooked, from the heat of compression.
Upon reaching crush depth, hull implosion has been theorized to occur so fast that the air inside the submarine is compressed and spontaneously ignites- if that’s true you’d die much faster than the time needed to take a cyanide pill
If the pressure at the depths is so high that it can ignite air, why isn't the bottom of the sea on fire all the time?
The air at the bottom of the sea is very well camouflaged as water, as such it successfully hides from the pressure.
It would ignite if the pressure finds it.
That only happens when gases are quickly compressed (adiabatically). It don't happens with incompressible liquids and solids.
Secret Atlantian technology
It's about the speed of the compression. If it's already compressed the heat gained from the compression will be lost to the surroundings till it hits ambient temperature.
When gasses compress they "release" heat. Think of "heat" being how often an atom "hits" another, not as some random force where things just transfer. When that atom is compressed into a smaller space it hits the other balls more often.
>Heat is atomic motion. Nothing more. The atoms in a solid do not sit rigidly in one place, but rather, vibrate as though they are connected by springs. The more they vibrate, the more heat the solid is said to have. In the case of gases, more heat means that the "ping-pong balls" are moving at higher velocities.
It's also why when gases expand into a vacuum in space, things "freeze" because they evaporate, and thus take the heat (Impacts with other atoms) with them. However over time, heat is transferred back into those objects raising their temperature to ambient again, though in space ambient can highly vary.
It's not just the air itself (or water) that is so much "catching on fire" rather the extreme pressure makes things that are normally not combustible very explodey i.e like carbon monoxide, the trace amounts of oils, greases and hydrogen in the air. It's the same concept on how a diesel engine works. Diesel is normally not easy to ignite but when subjected to high pressure in the cylinders of an engine it will combust without the need for a spark.
On the sub monitoring lower explosive limit is part of maintaining a safe atmosphere so changes in pressure can affect that. Same obviously with hydrogen and oxygen which is why on sub o2 is kept like at 16% underway
Because the world is flat you dipshit.
chumps with their "facts".
The bottom of the sea doesn't catch fire because all the water puts it out.
I know it's a bait meme post, but you can superheat steam to temperatures that set things on fire
A common aliment of Brony Navy Nukes when a steam line ruptures.
It is on fire but all the water keeps putting it out
because all the water puts out the fire silly

lol. I got put under for a few hours and when I was woken up it felt like no time had passed.
ITT submariner here, no they don't OP. As others have said at the depths a submarine would implode, it would happen so fast the human brain would not be able to process it, you would immediately pass out from the pressure change. At such high pressure the air around you basically will combust around you as the lower explosive limit of the atmosphere is off the chart. It's the same principal as how a diesel engine works only much more extreme. The boat would first elongate like a clown balloon as the hull would fail at it's weakest point then imploding at one end and exploding at the other.
That being said there are ingenious ways to off ones self on a submarine. Tying a rope around the shaft with a noose around your neck would be a sure fire way to depart this world as would jumping into the reduction gears.
I personally would just eviscerate myself on the exposed hydraulics for the rudder/stern plane.
Or a hop down suicide ladder would do the trick. What boat you on?
Nice try china, CoC, Ruskies, Ralienas, glowies, greys, reptilians.
No one actually believes that jumping down the suicide ladder will actually kill you. you stupid glowing loser. it's two fucking levels

You'll have an easier time getting in the aft gun locker. Take an axe to the nucleonics lock and just start drinking any chemical with "nitrate" on the bottle.

You fucking dweeb. Take your Metamucil you stuck-up shitdick.
I trust he's a submariner because I'm a submariner and I've done the same thing. You have to learn the boat inside out during your qualification, generally having to answer an unstructured barrage of questions from a senior technical rating on their specific system to get it signed off and move on to the next one. Once they've finished asking all the expected ones like 'what pressure is this, where is this valve, how do you operate it to do this in normal vs emergency' they like to test you with deliberately esoteric shit like 'if this system was offline and you cross-connected something else, how could you then simultaneously achieve blowing X ballast tank from the other end of the boat' or something similar. When goofing around with other people qualifying its pretty standard to quiz each other on ways you could line up systems to cause the most elaborate and techincally complicated deadly situation possible.
The bit about the air combustion and boat squeezing idk; there's a bit of mythology there but the forward hatches of scorpion were found blown open outwards.
Just imagine a piston firing off, you compress, compress and then BANG!
At the pressures we are talking about
Anything in the air that is remotely combustible now be the "fuel" to set out

Submarines? Not sure about surface navy brainlets, on subs it's smells like old cat ladies house vaguely ammonia like, I compare it to a old passgener airplane being cleaned so pretty nasty.
The smell comes from the chemical used in the CO2 scrubbers which is an ammonia compound that sticks to everything no matter how much you wash it. Big reason I'm notreenacting. That and the money.

Coming from one of the guys that welds them together I'm glad for your service bud, I assure you I try my hardest to make the boat as perfect as possible. I mostly spend my days correcting the mistakes of other trades and promise you we actually really try. I know every day I do the hardest I can possibly do to keep you guys under there okay.
>devotes about half a paragraph to the funniest/nastiest ways to have a nice day on a submarine
I think this says a lot about the mental state of sub crews.
Terminal boredom is a hell of a drug.
There is only one way a military man hopes to die, with honor. All else is useless gossip better left to women at the hair salon.

how to diesel subs balance change of buoyancy on account of the fuel tank emptying as it chugs along
also why is it not feasible to build big military subs that can descend to any depth on the planet like those specialized small subs going to the mariana trench
finally why are not drone subs a thing that launch out swarms of smaller submersibles for lets say, mapping out a large area of the floor with sonar coverage
First: water compensated fuel tanks.
Second: you need a lot of titanium...
Third: that's being worked on IIRC
can titanium hulls handle any depth? didn't the vatnik union have one experimental one built from it but it also had a crush depth
You could build one to handle any depth sure, but it'd be extremely expensive for limited tactical benefit - going deeper gives you an advantage to avoid detection, but at the same time due to the way sound travels in water unless you're already in proximity it could just hamper your ability to detect what you're looking for as the best water conditions for your sonar may not be at that depth. Getting in contact and then going deep would be pointless as the noise of the pumps for ballasting and hydraulics pushing your control surfaces actuating to do the manouever would cancel out the benefits. Then there's the fact that a hull could withstand that depth but you may not be able to run every system to its optimum or even at all as intakes for more vulnerable systems would need to be sealed off. There's nothing down there that needs a full sized sub to reach, you can just mothership for a more specialised vehicle to go super deep.
>how to diesel subs balance change of buoyancy on account of the fuel tank emptying as it chugs along
The diesel tanks are sea water compensating the diesel floats on top of the seawater and more sea water is naturally added as the fuel is consumed. Same deal on nuclear subs with diesel generators, usually the fuel/seawater is also apart of the reactor containment/radiation shielding schemes.
>also why is it not feasible to build big military subs that can descend to any depth on the planet like those specialized small subs going to the mariana trench
Just not feasible. There are nuclear powered deep submergence naval subs like Russia's Uniform, Paultus and Losharik which they use to fuck with undersea cables and other glowie spook shit. They are small and most require a mothership sub or surface ship to bring them to location. They are pretty much just a string of bathyspheres (like the deep submersibles you mentioned) that just arranged in a row and covered with a conventional submarine tear drop like outer shell/fairing + a small reactor.
>finally why are not drone subs a thing that launch out swarms of smaller submersibles for lets say, mapping out a large area of the floor with sonar coverage
It's already a thing, towed side scan sonar can also be deployed from a surface boat and brought to depth. Its possible to use commercial active bottom mapping sonar on the surface too. There are UUVs and ROVs about. So far nothing that is autonomous at least publicly unless you count that Russian Nuclear powered uuv/torpedo Poseidon.
They took away the ammo because the nukes were too suicidal. Plus common man who on PrepHole off themselves with a gun?
I'm very familiar with the shipyard yard bird shitters and their massive subsidized drain on taxpayer dollars and ships being stuck/ delayed in the yards well past their cycles. But I guess wagies gotta cagie.
Navy has the UUV program that has already reached the prototype stage, and that's being billed as autonomous so depends on whether you believe what they're telling Congress or not.
We're gonna see these nicked by the chinks using nets, idk if now is the time to start using them outside of training and wargames.
Navy men are good Christians and they don’t commit suicide. They go down honorably something landfags could never understand

Not true ! You just hate to see men being good friends and hugging each other, you’re probably a woman too
I don't think a submarine would crush instantly regardless of how many people ITT say so.
The main reason is because a submarine is compartmentalised, and because how a submarine actually gets to crush depth isn't going to be straightforward.
For example if a sub crashes into a sea mount it might lose hull integrity but only some sections might decompress. I assume in that case internal compartments would decompress as the sub sank long before the other sections of the hull.
And another issue is that crush force might overpressure compartments long before those compartments failed, which I suspect would be far less than the overpressure of say...an IED.
You might have a failure related to life support systems, specifically air filtration. Toxic gas given off by a fire or related chemical accident.
Then there's the issue of military operation where a mechanical failure might force you to surrender, but the risk of the vessle falling into enemy hands is too great and the decision might be made to sink the sub.
>The main reason is because a submarine is compartmentalized
On modern double hulled US subs there really only two compartments excluding the reactor. The engine room being one of them. Russian boats do have multiple compartments realistically a catastrophic failure like that will doom the boat.
Also again at the depths and pressures we are talking about its not going to be drawn out like that. Were are talking pressures well over 6,260kPa.
I'm sure it would be terrifying as the sub slowly sinks as valves and seals begin to fail and noticeable buckling happens no doubt. I know people on the USS San Francisco when that boat rammed into a sea mount and I was told some people did in fact break down as they at first could not maintain positive buoyancy.
>I was told some people did in fact break down as they at first could not maintain positive buoyancy.
Elaborate on what you were told, this would be interesting.
The US so not have double hulled subs
I'd be interested in hearing the audio recordings of this.
reminder that chinese and russians actively create and patrol these threads to get useful idiots to suck themselves off online about how badass their job is and gather low-level intelligence to piece together. posting ANYTHING about the current submarine force is heavily looked down upon and you know your security manager would flay open your nutsack if he caught you here
now go do your cyberawareness wagies
changs just try to copy everything that is fed to them so prime opportunity for false intel shenanigans for many lulz to be had. Russians with the state on how poor, underfunded and corrupt they are in general are a complete meme at this point. Even if they get their hands on the technical blueprints and engineering notes or even actual pieces of equipment. Most they could do for maximum damage is sell it to changs
There is literally nothing on this thread that's even remotely anything sensitive. There's an old sonar tech by the name on YouTube jive turkey that got a talking with the feds for going into detail on sub sonar. Also everyone on a sub drilled OPSEC into their heads day one. We have tours of the subs from family and schools so it's nothing new
Is it true that a quarter of all submariners wear navy programming stockings?
Real navies yeah, not the US navy
