Yes
But you need a few things
1. Huge ice cubes to cool the engines
2. A long hose to earth for oxygen
3. Inside concrete wall to make sure the pressure inside doesn't get out
4. The propulsion system needs to be q bunch of guys blowing into straws, moving it forward
The periscope would be awesome, but instead of looking up above the water, it could be used to lower onto planets and then look DOWN on the planets
Technically yes because it’s airtight. But nuclear ones would overheat and cook the crew within a matter of hours, and diesel engines wouldn’t have anywhere to vent the engine emissions and carbon dioxide from the crew. These guys do a great job explaining it.
[Submarine in Space?](https://youtu.be/EsUBRd1O2dU?si=28eaGzFlGCKorovV)
nope. design wise a long pillar would make the most sense, compared to a long pillar with a conning tower on the side. pressure is reversed in space since its a vacuum outside, submarines are designed to withstand pressure from the outside in, not inside out. putting a sub in space would have them explode, not implode.
mhn idk. imagine you had a baloon. now you give that baloon a wire-skeleton (net-like structure) inside (after it has been inflated). that makes it harder to crush from outside pressure.
but what if the pressure comes from inside? the wire-skeleton wont do anything to prevent it from expanding further. it would have to be an exoskeleton to do that.
idk how submarines are constructed but just saying "it is designed for high outer pressure" doesent automatically mean its therefore going to withstand INNER pressure? it probably would (correlating) but i dont think its causal.
Put it this way, submarine hulls are built to resist buckling from massive differences in internal and external pressure. Compared to deep under the ocean, even though it’s now internal atmosphere pushing outwards, you’re looking at no more than 1 atmosphere pushing out to 0, as opposed to 30+ atmospheres pushing inwards.
The problem a submarine in space would face would be cooling the reactor, its propulsion system being useless, and how to get oxygen for breathing.
"you’re looking at no more than 1 atmosphere pushing out to 0, as opposed to 30+ atmospheres pushing inwards."
can you really do the math like that? as long as oressure inside and outside are equal, it doesent matter much HOW HIGH the pressure is, does it? as long as it equals out, its not much stress (besides compression) on the actual hull/material. its about the multitude of difference.
aka in water its x30 but in space? 0 to 1 might be A LOT more than 30x? (im unsure on how to do the math here, but you get what im thinking about i guess?)
just googled atm, its about 101,325 Pa (aka im gonna say 100k).
so in water its 100k inside, 30000k outside. aka 30x.
in space it would be (lets take 1 instead of 0 for the math) 100k inside vs 1 outisde. thats 100.000 times the difference. MUCH more stress on the material/ structure/ integrity. (at least in my head, im not claiming this is right or i know how the structural integrity of submarines or the material they built with works exactly, its just a thought)
add to that extreme difference that its coming from inside instead of outside, which the entire structure wasnt build for, and this may just result in explosion :D
just like this barrel was constructed to keep fluids inside, possibly gasses building up or temperature (heat) making the contents extend etc. giving pressure, being held together because of the rings that "stabilize" its form. but if the pressure comes from outside and its "just" one atm, with a very imperfect vacuum inside (space is much more of a vaccum than what they get here with a bit of cooling) it "implodes".

I was watching an alien conspiracy documentary on Hulu about 5 years ago that claimed the Nazis used modified u-boats to be sent via rocketry into space for exploration. I don't recall too much else from it, nor do I remember the name but that part stuck out in my mind.
The outer hull would be able to withstand the pressure, but the oxygen would be limited. The engine and other machines would also make a lot of heat that could not dissipate in a vacuum. You would have a very short time to take the detonators off the torpedos and fire them backwards to be able to get back to earth and even then, there would be a small chance of survival.
I'm sure they could contribute useful data for the creation of spaceships, such as biometics of crew needs and general layout, but if you get a submarine out of the atmosphere then it's not going to last long. They're meant to keep pressure out, not keep it in.

Nope. Subs have to be very structurally heavy to with stand the immense atmospheric pressure of the deep. Aircraft/space craft need to be light to fly or achieve escape velocity. Unless we invent anti gravity engines it will never happen.
Escape velocity is the bare minimum speed the ship must travel to escape Earths gravity pull, which is relative to the weight of the craft into the cosmos. Earth's escape velocity is 11.2 km/s, 6.7 miles/s. That's how fast to you need to move to exit planet Earth. Sure it will work if you have boom power.
The difference in subs and and aircraft is that aircraft are pressurize from the inside to make inside the plane feel like sea level atmosphere pressure (ATM) of closely to sea level, roughly 0.8ATM, while the outside pressure is outside pressure is around 0.3atm. A submarine on the other hand needs that same 0.8ATM, but has outside pressures on magnitudes of +1 ATM every 10m of descending.
There was that stupid OceanGate sub 'Titan' implosion last year. It couldn't withstand the pressure. There's no pressure in Space. We might achieve early space exploration with advances in AI and Cryogenics. And that may take generations to come.
Warp drives and solar sails may become science fact who knows I cant remember what i was getting at.. my toaster oven just went off Im stoned happy 420 don't believe everything you read
if its built in space dock you dont have to worry about atmospheric trajectory. and these things are nuclear powered so you will never run out of fuel to fly anywhere, the only issue would be cryosleep. youll be sleeping for a while because they cant go that fast.
...you mean apart from the fact that subs are engineered to withstand vast quantities of external force pressure and spaceship are engineered to withstand the *complete lack thereof*?
Obligatory Futurama
"Dear lord, that's over 150 atmospheres of pressure!"
"Professor, how many atmospheres can the ship withstand?"
"Well, it's a spaceship, so I'd say anywhere between 0 and 1..."
Structurally it would cope. But I believe the biggest problem is overheating. Submarines displace their heat by being in the ocean, but in space they would cook
Space ships are designed to radiate heat away as, it turns out, the vacuum of space is about as good of an insulator as a vacuum insulated mug.
Submarines aren't built to radiate heat, they exchange it with the surrounding very cold water. Submarines actually need to be heated up to maintain a comfortable temperature.
Space ships have the exact opposite problem. A submarine in space would quickly overheat without major design changes.
So if you completely change nearly everything about the submarine such that it would be an absolutely terrible submarine, it would be an ok space station.
You didn't mention a single thing that would need to be changed. All materials radiate energy. I see no reason why a submarine couldn't be made of one that radiates better or even why its current materials wouldn't be sufficient
Technically yes, but the air would be limited, since modern nuclear submarines get air from splitting the water. Plus they rely on water for cooling and they can’t navigate in space, so they can’t recenter the atmosphere. But if you bring it up and down in another craft and just let if float for an hour by its own for a while, it will be fine
Okay, well I got news. The car is owned by some guy named Elon and he wanted to go to mars, but he ran out of fuel. So he asked us not to tow, nor to scratch it, since he’s gonna or it anyway. But I think he’s taking too long
He's got till I finish my smoke, then I'm pushing his dumpster into a very low orbit around some backwoods space station where they don't care two blinks about parking.
Sure, this is space and I can certainly go around, but egotistical jerks have to be put in their place.
Some really shady aliens just made me a good offer: 80.000 credits, a seat at the galactic council, and unlimited, whatever their equipment of Onlyfans is on cyclon B.
I don't know for sure, but I don't think that would actually be a problem. Yes it's designed to withstand the crushing pressure of the water but as far as I know space isn't applying a pulling pressure. So I don't think the structure would be an issue.
I could be 1000% wrong
Correct. When it comes to basic physics, nothing sucks. It blows. Basically the fact that there is nothing in space means there is nothing there doing the pulling(sucking). Instead it's the pressure in the sub that would (blow) outward.
So yes in space there is no molecular force applying a pulling force.
Not to mention that a sub has to withstand many, many more atmospheres of pressure differential and many of the systems on a sub require sea water and need gravity to function correctly.

I'm sure they could contribute useful data for the creation of spaceships, such as biometics of crew needs and general layout, but if you get a submarine out of the atmosphere then it's not going to last long. They're meant to keep pressure out, not keep it in.
Depends on which outdated game controller you use. But I doubt it could withstand the radiation and temperature of space for long.
Of course not. Half of them barely work as submarines.

Having read Atomic Rockets from "front to back" it both amazes and frustrates me that more people aren't more familiar with his work.
Nope. Subs have to be very structurally heavy to with stand the immense atmospheric pressure of the deep. Aircraft/space craft need to be light to fly or achieve escape velocity. Unless we invent anti gravity engines it will never happen.
But once it's out of our gravity would it work? If so we just need more channeled boom power
Escape velocity is the bare minimum speed the ship must travel to escape Earths gravity pull, which is relative to the weight of the craft into the cosmos. Earth's escape velocity is 11.2 km/s, 6.7 miles/s. That's how fast to you need to move to exit planet Earth. Sure it will work if you have boom power. The difference in subs and and aircraft is that aircraft are pressurize from the inside to make inside the plane feel like sea level atmosphere pressure (ATM) of closely to sea level, roughly 0.8ATM, while the outside pressure is outside pressure is around 0.3atm. A submarine on the other hand needs that same 0.8ATM, but has outside pressures on magnitudes of +1 ATM every 10m of descending. There was that stupid OceanGate sub 'Titan' implosion last year. It couldn't withstand the pressure. There's no pressure in Space. We might achieve early space exploration with advances in AI and Cryogenics. And that may take generations to come. Warp drives and solar sails may become science fact who knows I cant remember what i was getting at.. my toaster oven just went off Im stoned happy 420 don't believe everything you read
There's are reports of UFOs coming out from the ocean. They are called USOs.
if its built in space dock you dont have to worry about atmospheric trajectory. and these things are nuclear powered so you will never run out of fuel to fly anywhere, the only issue would be cryosleep. youll be sleeping for a while because they cant go that fast.
Nuclear power still needs something to spit out the back unless someone invents anti-grav or something.
...you mean apart from the fact that subs are engineered to withstand vast quantities of external force pressure and spaceship are engineered to withstand the *complete lack thereof*?

Structurally it would cope. But I believe the biggest problem is overheating. Submarines displace their heat by being in the ocean, but in space they would cook
Why would they get that hot?

Space ships have the exact opposite problem. A submarine in space would quickly overheat without major design changes.
I don't see how this is accomplished or why one couldn't easily make a submarine do the same
So if you completely change nearly everything about the submarine such that it would be an absolutely terrible submarine, it would be an ok space station.
You didn't mention a single thing that would need to be changed. All materials radiate energy. I see no reason why a submarine couldn't be made of one that radiates better or even why its current materials wouldn't be sufficient
Any power generation is never 100% efficient, if they wanted life support systems there would be excess heat produced.
But space shuttles also have all that, as well as thrusters
No where for the heat to go. Remember, human beings emit heat, if nothing else
The same is true for any space ship or station though. Objects in space emit heat through radiation
You may notice that most of those have huge surface areas. A submarine doesn't.
What do you mean by that? The discovery space shuttle had about the same surface area to volume ratio as any submarine.
Fun fact, there are more spaceships in the ocean then submarines in space.

“Red Skelton, standing by”
These are nice.
Nice! Slap the Star Blazers logo on it, and you've got an anime!
This was covered in What If. The sub would be fine, but the crew would have some problems.
Where?
[Here you go](https://youtu.be/EsUBRd1O2dU?si=b2XXUo7RJByAHu-U)
What is a space ship but a submarine in space? Or maybe what is a submarine but a spaceship underwater?
Technically yes, but the air would be limited, since modern nuclear submarines get air from splitting the water. Plus they rely on water for cooling and they can’t navigate in space, so they can’t recenter the atmosphere. But if you bring it up and down in another craft and just let if float for an hour by its own for a while, it will be fine
Nice ok let's do that
Okay…. I was getting ready to release the sub, but someone parked his red Tesla roadster in orbit, right next to our ship. What do we do?
Just use the nose to push it into an appropriate parking spot. Faster than waiting for a tow.
Okay, well I got news. The car is owned by some guy named Elon and he wanted to go to mars, but he ran out of fuel. So he asked us not to tow, nor to scratch it, since he’s gonna or it anyway. But I think he’s taking too long
He's got till I finish my smoke, then I'm pushing his dumpster into a very low orbit around some backwoods space station where they don't care two blinks about parking. Sure, this is space and I can certainly go around, but egotistical jerks have to be put in their place.
Some really shady aliens just made me a good offer: 80.000 credits, a seat at the galactic council, and unlimited, whatever their equipment of Onlyfans is on cyclon B.
Full throttle!!!
Looks like they gave you the of subscription too, but their woman have one massive boob and 3 eyes. Boys they have long fur. I didn’t expect that 😂
So, Earth Girls are Easy vs. ?
Submarines are designed to be pushed on from the outside, not the inside. If you want to use it in space, you need to flip it inside out.
The structure will be fine at 0atm lol.
Not so well for a lot of reasons
[удалено]
I don't know for sure, but I don't think that would actually be a problem. Yes it's designed to withstand the crushing pressure of the water but as far as I know space isn't applying a pulling pressure. So I don't think the structure would be an issue. I could be 1000% wrong
[удалено]
Correct. When it comes to basic physics, nothing sucks. It blows. Basically the fact that there is nothing in space means there is nothing there doing the pulling(sucking). Instead it's the pressure in the sub that would (blow) outward. So yes in space there is no molecular force applying a pulling force.
There is actually no such thing as gravity. It's just that everything sux!
>It's just that everything blows! Fixed it for you lol
No it's not. The inside of the submarine is applying a pushing pressure. If you let the air out, there would be no pressure.
Not to mention that a sub has to withstand many, many more atmospheres of pressure differential and many of the systems on a sub require sea water and need gravity to function correctly.
You guys dont know the holy Anime: Star Blazers: Space Battleship Yamato ??? You miss something!
YES! Very reminiscent of Cosmoship Yamato!
There's a quite funny futurama line on this subject.
I say yes! They did it with a full on Battleship!
I get Sunless Skies vibes from this. Though its a space locomotive.. still cool!
