Military subs can only use a small part of the ocean's depth, usually within 2,000 feet/610m. Proposals for ultra-deep submarines have existed for decades, but have not been funded. How would a sub with a 35K/10,700m range change warfare?
What exactly would it do at that depth? Would it be able to communicate? Would they need to develop new weapons (SLBM etc) that can handle that depth of the weapons we have now work?
Where in the world would you be able to operate at that depth?
>>28060472
depth charges cannot reach them
a depth sta missile can be launched at any depth, size granted
>>28060472
Another question could be "how would we fight them" if deployed by hostile nations.
>>28060490
>depth charges cannot reach them
How so? You drop them, they sink, they go boom.
Ofc you would need to develop new ones but that can't be that hard.
>>28060500
Perhaps some kind of AP torpedo? Like a metal rod basically meant to punch a hole in the hull. Depths like that can't even handle that much and would most likely result in one fucked sub.
could it be detected / detect enemies in the area at such a depth?
Can sonar work effectively at those depths for either party from surface craft?
Why would you ever want to go deeper? Deep sea pressure is already terrifying enough. The Byford Dolphin incident comes to mind.
>Coward, Lucas, and Bergersen were exposed to the effects of explosive decompression and died in the positions indicated by the diagram. Subsequent investigation by forensic pathologists determined Hellevik, being exposed to the highest pressure gradient and in the process of moving to secure the inner door, was forced through the 60 centimetres (24 in) in diameter opening created by the jammed interior trunk door by escaping air and violently dismembered, including bisection of the thoracoabdominal cavity which further resulted in expulsion of all internal organs of the chest and abdomen except the trachea and a section of small intestine and of the thoracic spine and projecting them some distance, one section later being found 10 metres (30 ft) vertically above the exterior pressure door.[5]
>>28060534
>All of his thoracic and abdominalorgans, and even his thoracic spine were ejected, as were all of his limbs. Simultaneously, his remains were expelled through the narrow trunk opening left by the jammed chamber door, less than 60 centimetres (24 in) in diameter. Fragments of his body were found scattered about the rig. One part was even found lying on the rig’s derrick, 10 metres (30 ft) directly above the chambers. His death was most likely instantaneous and painless.
Holy shit
>>28060534
>>28060627
Saw the autopsy photos for Hellevik, literally unrecognizable as a human being. Just a pile of red mush, absolutely horrifying.
>>28060532
We use sonar to map out the deepest parts of the ocean, so I'm guessing yes.
>>28060534
Visual aid to what happened to that poor dude.
>>28060708
>>28060696
Dissolved fats were also found in blood samples, indicating that the blood boiled during the event.
>>28060696
That photo also showed that his watch exploded, since it was sealed.
>>28060737
High pressure is almost as terrifying as a vacuum
>>28060745
Yeah, I guess the only good news is that death from either is fast.
>>28060472
by being unmanned and equipped with a small nuke to cause tidal waves on costal nations.
>>28060472
well, if such submarines were to exist they would have to be drones
at that depth a pressure hull large enough to hold any significant crew is difficult to build and the size limitations would create range limitations.
make it a semi intelligent drone capable of operating far from friendly bases and you have the ultimate merchant shipping raider.
>>28060472
Soviet tried. Creating a super depth torpedo is cheaper, than building of super depth submarine.
That's... that's awesomely retarded, anon. Sounds like something Reagan would've loved.
>>28060532
Sound travels faster through denser media, so i'd assume sonar would work better the deeper you go.
>>28060999
Water stays the same density through all depths. Only temperature changes its density, and that's only by the tiniest bit.
>>28060787
This is pretty much the only way i could see it being anyway worth it.
Being that deep means firing at or detecting surface shit is nearly impossible. Make a small drone, preprogram the course into it. Have it sneak up to a seamount or island chain in the correct position and detonate explosives in a way to cause a tidal wave that hits your enemy's coast.
>>28061025
There is at least one large temperature gradient in the ocean, and being below that makes detecting shit above it very hard.
https://en.wikipedia.org/wiki/Thermocline
>>28060787
That doesn't work.
http://what-if.xkcd.com/15/
>>28060754
Ekshuelly you can survive for around 30 seconds in vacuum without any protection without any permanent damage
>>28060490
They don't use depth charges anymore, torpedoes have the advantage of homing in on a sub. Chucking a couple of tons of unguided explosives into the water was found to mostly just kill a mess of fish. The traditional post-action fish-fry was missed.
>>28060502
It's quite a precise art though surely? Like a bombing run but much slower. It takes quite a bit of time for them to sink and with something that deep detecting and calculating distances would be more difficult
>>28060627
I know right? We should totally use that a method of execution and direct the spray of viscera onto any death penalty protesters.
>>28060472
This is a weird thought, but consider that a submarine capable of surviving a 35,000 ft deep would need to have immensely durable construction. If you have a material that man withstand that much pressure, wouldn't the submarine be immune to explosives? It would be like a terminator submarine. You can shoot it with torpedoes and depth charges but it is so durable that it will survive and accomplish its mission regardless.
>>28060745
Exposure to hard vacuum is actually neither quick nor messy. Its only a -1 atmosphere pressure difference and the human body can hold itself together. The water in your lungs will boil off and you'll asphyxiate.
>>28060786
goddamn Sperm Whales are hardcore
>>28061699
No, that's not how it works.
Deep sea submersibles are designed to deal with an INTENSE amount of atmospheric pressure. If you set off an explosive near a deep sea sub, you just compromised the hull integrity and it will sink. At extreme depths the thing with implode.
>>28061435
Even the most powerful nuclear weapon releases orders of magnitude less energy than a serious earthquake. You would need many warheads to trigger a rock-slide capable to creating a tsunami.
>>28061715
You see those scars on the whale? Those a battle scars. The sperm whale is so hardcore that it eats giant squid. Other whales just it tiny fish and plankton and stuff. This mothafucker goes down to the pitch black depths and wrestles with architeuthidaes.
>>28061741
I guess I don't understand the proper physics then. So the submarine could withstand intense atmospheric pressure but still be vulnerable to underwater explosions?
>>28060472
You know the entire Joe Buff submarine novel series is about this idea. The main character is the captain of a special nuclear submarine made of some advanced composite that can survive at extreme depths.
It's very heavy in technical jargon and I never liked any of the characters enough to keep reading, but they're supposed to be very technically accurate as far as their depiction of submarine warfare goes.
>>28061758
>>28061715
Devils fish!
>>28061781
>I guess I don't understand the proper physics then. So the submarine could withstand intense atmospheric pressure but still be vulnerable to underwater explosions?
Imagine an egg. You put it in your hand and close your palm and squeeze. Even if you are very strong you won't crack it. But if you hit the egg just a bit with an edge of bowl it cracks...
>>28061837
>Even if you are very strong you won't crack it.
Is that a challenge?!
>>28061855
Well, the sphere on deep sea subs are about 2.5 inches thick of high strength steel. The deep sea challenger that James Cameron piloted dowm to 36,000 feet had such a sphere that could withstand 114 Pascal's, or 11600 PSI.
You crack that shit at depth, and you're dead.
>>28060534
>>28060627
Found the autopsy of Hellevik, if anyone is intrested.
>>28061913
Fugh
>>28060708
>>28060472
Simple answer: because they would be useless as they couldn't travel at that depth without having to go up.
Close the thread now
>>28061913
Brutal
>>28060786
god damn that is fucking terrifying.
>>28060786
>only 10% of the ocean has been mapped
It's crazy how we actually know more about space than our own oceans.
>>28061758
I propose we make the Sperm Whale the official aquatic mammal of /k/, in honor of its species' warrior prowess!

Pressure resistant constructs rely on the pressure being equal on all sides. They transfer the force around, so that the pressure on one side is what resists the pressure on the other. A sudden fluctuation on only one side causes the whole thing to come apart.
>>28062079
Light passes through space far easier than it does the ocean. That makes space easier to observe.
>>28060786
see this is why I think we should honestly try to fully explore the ocean before we go into outer space much more. I mean fuck, for all we know there actually could be the remnants of a lost ancient civilization down there that has Mass Effect-tier technology or something.
>>28062079
>>28062107
>Cameron said: "I landed on a very soft, almost gelatinous flat plain
everything about the Challenger Deep seems so alien.
>>28062123
I applaud Cameron for doing that stunt. I have almost no phobias but being that far underwater would frighten the ever loving shit out of me. I mean just one tiny microscopic crack in the hull and he'd be scrambled eggs before he even knew what happened.
>>28062107
If we colonize space before exploring the ocean, we'll be fine if something happens to the earth. If we focus on the oceans then get smacked by a meteor, or another foreign object. It was all for naught.
>>28062149
You're being silly if you honestly think humans will have enough of a population in space any time soon. Even if we someday do have like 100,000 people in space, the colonies wouldn't be completely self sufficient and they would most likely die off if Earth were destroyed.
And colonies underwater would probably be able to survive most catastrophic asteroid impacts. Again, the subject of self reliability comes up though, because an asteroid impact would kill off a lot of sea life. Not necessarily because of them burning to death or something, but because the change in weather would kill off algae and that is basically the building block for the aquatic food chain.
>>28062015
Why can't they travel at that depth?
>>28062190
It's farfetched to think an undersea colony would survive a stellar impact. It depends on the size of the object sure. But even if the object hits hundreds of miles away, the amount of water that would be displaced by a 1km wide object would be immence and absolutely fuck an undersea colony.
A colony of 100,00 would have to be self sufficient if it was that size, 10 people would need outside help. 100k? Yeah nah.
>>28060504
So, basically like outfitting all Destroyers with giant nailfuns slapped to the hull?
>>28060472
A military sub going that deep serves no purpose, it would just end up being an insanely expensive oddity.
The Russians built their akulas to go to around 2000 or so I believe and that was only because the entire hull was titanium. The whole thing. Even then they could only do a couple trips to test depth in the boats life due to the brittle nature of titanium
>>28060786

>>28063512
Fuck the ocean. Fuck the creatures that reside down there, fuck the immense pressure, fuck the lack of light.
Fuck it all. Nuke the ocean before it engulfs us all.
>>28063512
>/k/ should go innaocean
i can already see a drunk /k/omrade in a big gas tank coated in cosmoline readying himself to be dropped off from an old rusty oil rig
ultra deep UAV's could be a possibility
You don't need a strong hull if the internal of the sub is equalized in pressure to the outside
>>28061715
And we used to hunt them in wooden boats with, essentially, spears.
Humans are hardcore as fuck.
>>28060472
It wouldn't really change the actual shooty bit of warfare, since they'd still have to rise to/near to the surface to do SHIT weapons-wise.
Not to mention missile hatches would have to go away, there'd be literally no way with current or near-future tech to pressure-proof them, so you'd be stuck with flooded-tube torpedo launchers that would be a PITA to reload/rearm due to needing massive fucking pressure hatches to keep them from imploding into the crew compartment.
>>28061913
We need to publicly execute criminals via this method. I am not being edgy, think, seriously think the image this will leave into peoples minds on how serious crime is handled.
>>28062052
And remember, one of Jupiter's moons...or is it Saturn's? Anyway, has an ocean 50 MILES deep.
>>28064130
We must strike first, before whatever nightmares dwelling down there turn their attention to us.
>>28062123
can somebody provide me a link about James Cameron's expedition? stuff he saw or found?

Yeah, kill all witnesses so you don't get caught

Fuck yeah enceledus! Or was it europa?
Exploring it would be very hard however, ocean is under many miles of Ice I know there is a proposed mission for SLS to have an orbiter for europa, they have actually been doing some small talks about adding a 2-300kg lander on it. Won't happen till mid to late 2020s however
>>28062149
It's like you don't even want to experience the embrace of the Wau.
>>28063250
According to the book, they're only a couple of hundred feet down.
>>28064289
Unlikely to get any real depth in it's oceans. The pressure is something like the entire weight of Everest per square inch.
>>28063578
i think you meant usv
>>28064471
are you sure? didn't they have to wait in decompression on the way back up?
>>28064482
Shouldn't pressure be a factor of gravity too?
It's a fraction of earth gravity there.
>>28064106
It'd be more humane and less costly than traditional methods, as it happens.
Just grisly.
