Of course, igniting the rocket engines that close to the hull might SLIGHTLY exacerbate the heat buildup problem. 😂 You probably know this, but even in the cold cold ocean, the missles are launched out of the tubes by steam before the engines kick in.
Which brings up the inevitable followup question, how much bracing would be required to keep the backwards facing rocket designed to go very far up and then sideways from creating a new hole on the other side of the sub or causing a big mess inside. Thats the important question we need answered.
@@TsandLman Which would be another way to get some ∆v for the de-orbit (since I'm sure throwing a rocket out the hatch would create some recoil that would normally have been absorbed by the ocean)
Regarding the reverse question, I'll always remember the _Futurama_ line: "How many atmospheres of pressure can this ship take??" "Well, it's a spaceship, so between zero and one."
Though presumably there are safety margins built in, especially if the ship is designed to visit planets with denser atmospheres. (It's still a good joke though!)
I am reminded of the Planet Express Ship's forced deep ocean dive on _Futurama:_ -"Pressure at 20 atmospheres...30 atmospheres!" -"Professor, how many atmospheres can the ship stand?" -"Well, it's a _spaceship,_ so I'd wager anywhere between zero and one."
i used that same logic to argue with someone when we were talking about a hypothetical setting of a "sky city" on Neptune. Since part of the goal was to go deeper into neptune's atmosphere and explore, i argued they'd need more submarine-like equipment, like depressurization chambers. This other person argued "they have spaceships, they don't need submarine stuff".
Futurama has the best science jokes of any series I have come across. Robot Mafia running numbers. Nothing fancy, mostly 0's and 1's Freezing on Neptune. Bender complains, it's so cold my processor is running at peak efficiency
So disabling the missile's warheads is of course necessary. If you want to survive the reentry, you might also need to eject the submarine's reactor too. It won't explode, but it will crack apart and spew uranium everywhere in the vicinity, so that's kind of bad.
@@JLG331 given there are also a bunch of nukes on board, that might be a pointless endeavor. Even if the missiles were perfectly disarmed so they wouldn't go off on impact, that's still a whole lot of uranium going up in smoke. Plus the fuel lockers for the reactor.
It just needs some upgrades. Nobody says you have to de-orbit and return to the surface. Either use a shuttlecraft or have Scotty beam you down. I hear Amazon has some great deals on oxygen generators and thermal radiators this month. That and an Impulse Drive unit and you will be set. Make it so...
@@Ydrakar Do you realize how much that is? I mean, that's more than a few hundred thousand tons of air. And also, yeah, Helium floats because it's light. And a few hundred thousand tons is not light. It's, well, a few hundred thousand tons. The question is, how much volume will that much helium take, even maximally pressurized (which will technically make it solid).
@@CapnBlud The helium doesn't float because it is light, it floats because it is less dense than air. A "few hundred thousand tons" of helium would still float and a gram of metal would not. The problem is the volume, like you said. Besides, if you could potentially float, you wouldn't reach outer space because things float because they are less dense than air. As the air pressure reduces, that effect would reduce as well. In that case you need another external force to give you speed to make you go into orbit. Otherwise you would never leave the atmosphere
The ending made me feel validated for thinking "Hopefully making sure the missiles doesn't detonate as a result" during the part about using the missile's propulsion to get back.
You cannot easily get fusion weapons to detonate as intended, unintentionally. Er....maybe that's not the best way of saying it, but it's extremely hard to get fusion bombs to work as designed accidentally. You could smash them all into the ground, no problems. Well, not 'fusion bomb explosion' problems.....other problems, yes. But they do tend to pale in comparison.
There might be enough of a heat shield to be initiated as an ODST or helldiver. And your squad has 20 chances to figure it out, and whatever time there is left.
I could be wrong, but It’s my understanding that non-conventional bombs like that would need to be detonated with a trigger mechanism. Even the old style of “bullet” atomic weapons where the fissile material was essentially encased in an explosive sphere to cause the chain reaction would occasionally be a dud due a slight imbalance in the explosive. The main concern with them falling out of the air is the fissile material would be flung everywhere. This guy sounds like he knows what he’s talking about though.
I really appreciate how you went through all the trouble of explaining how a Submarine would work in space and the logic of how it can return… but never once questioned how it got there 😂.
The Wizard Who Only Knows The Spell “Teleport Submarine” teleported a submarine on top of the head of the last guy who questioned the motives of The Wizard Who Only Knows The Spell “Teleport Submarine”.
I would have to wonder just how airtight a sub would be. The seals are designed to have positive (by a large amount) external pressure, and not negative pressure. So to me the seals are "pointing in the wrong direction". It might leak like a sieve in space.
There'd likely be some leakage, but I wouldn't expect it to be huge, primarily because the individual compartments inside a sub are designed to be water-tight both-ways, in case a compartment floods. Like the doors and bulkheads between the missile deck and the engineering deck will keep the engine room pressurized if the missile deck floods, but will also keep the missile deck pressuized if the engine room floods. And it's not like the hull requires pressure to be watertight either, else a sub would leak while on the surface. Plus all the external hatches are redundant, if not actual airlocks; we wouldn't want a single failed hatch to sink a sub.
Yeah, that was my thought as well. You could possibly seal off areas that are particularly bad and save the crew from decompression but the ballast tanks are almost certainly going to leak, likely causing significant spin. I also doubt you can seal off the tertiary coolant feed tank for the reactor.
I think that while seals can be biased in one direction, unless they're deliberately designed to be uni-directional (and there'd be little reason to do that), they'll still have some resistance the other way. And because of the magnitude of difference between the negative pressure of 1 atm > 0 atm and the positive pressure of a couple hundred meters of water, the seal would have to be like 100x worse in one direction than the other for it to be an issue. I think it's more likely that the 'bias' of the seals would be like near 2:1, not 100:1
One of the ways they test the water tight integrity of a submarine before diving is to overpressure the boat and hold that pressure long enough to see if there's any leakage. I'm pretty sure they don't go all the way up to two atmospheres but the principle is the same. The seals might not be able to take as *much* pressure outward instead of in, but they can take at least that much.
Im very happy that you mentioned the heat-issue in space, because it feels like every movie and game completely ignores that part and just goes with "yeah its super cold in space" and then you get people that insta-freeze or a space ship that somehow builds ice on the walls because of a hull breach etc.
So now I am confused about why the crew on Apollo 13 got so cold. Were they shielded from the sun and unable to reduce the amount of heat radiated away?
@@JaniceinOR As far as i remember reading, the issue was that the outside of the craft was very well isolated, so while it did heat up significantly on the surface, barely any of the heat made its way inside. On the other hand, they had no possibility of heating the craft up and no way to really get rid of the moisture that was building up inside. Given that they also spent a significant amount of time outside of the suns reach, they struggled to keep the craft warm as the men alone were not enough to keep it warm. You also have to keep in mind that there was still a lot of warmth cooled down by the crafts cooling systems, otherwise the electrical devices would have overheated within hours. So it was an issue of freezing but having the systems to make it home, or being warm but unable to come home. I might misremember though.
@@Robonator14 What do you mean they spent a significant time outside of the sun's reach? They spend like half an hour in the moon's shadow, out of a flight of over 142 hours.
@@WJS774 As far as i remember reading, the capsule they were in spent quite some time in the shadow of the service module. Later they did indeed end up in the direct sunlight, but the capsules design prevented the heat of the sun to enter the ship.

+50 atmospheres implying -1 atmosphere is fine might come down to how seals are enginered. Some might depend on being pressed together from the outside.

I'm pretty sure they don't go all the way up to two atmospheres but the principle is the same.

In addition to Willy's brilliant reply. Remember that subs are designed to work on the surface of the water too. If they relied on the mountain of outside pressure from the water at 100m depth, they'd leak and thus sink whenever they surfaced.
@@MGSLurmeyThat's not how that works. Many directional Seals are almost like a one way valve. When there is no pressure on them they have a small "spring force" holding them tight against very low pressures. As the pressure increases, it needs to be squeezed against the sealing surface increasingly hard to seal. The increasing pressure is used to provide the sqeezing, so the higher the pressure the better the seal. Put the pressure on the wrong side of the seal however and you lift the seal away from the sealing surface, and let everything through.
That comparison to sparks when grinding got me to understand what you meant. I really appreciate comparisons/metaphors that fit that well, makes things way easier for us dummies out there
The heat issue is the reason that the original design for Discovery in "2001: A Space Odyssey" had huge triangular wings on both side of the ship. They were heat radiators. Stanley Kubrick decided to delete them, which is why the final design for Discovery is basically a ball on the end of a stick. Kubrick thought the audience would be confused by wings on a spaceship, and he was probably right. But in reality, you would need those big radiator surfaces to get rid of the waste heat from the nuclear reactor. If you read Arthur C. Clarke's novel version of "2001," you'll see that he describes the original design. In the book, Discovery is shaped like a giant arrowhead.

This is also a very specific question I had to think about. I ran a fantasy/sci-fi campaign in D&D and players had access to a submarine, and a girl who could teleport and take large objects with her. They needed to go into space. I didn't consider the reactor immediately blowing up, but I did crack the hull a bit from the sudden change in pressure and the fact that one side was in the hot sun and the other side in freezing darkness. Players founds the leaks via incense and followed the smoke trails, which made me very proud. Also instead of maneuvering using missiles, one of them put on a space suit, stood on the sub's hull and fired guns. For hours. Not a great change in velocity, but they didn't need much. The initial teleport had, fortunately, brought them pretty close and over the course of days they drifted close enough.
I was wondering just how a bunch of fantasy folks got a hold of a submarine but the fact that someone propelled it with shooting firearms for hours sounds so very American :D

@@thetiredladdy almost all modern ammunition contains all the fuel and oxidizer it needs to function, except things like cruise missiles which are propelled by air-breathing jet engines.

@@xxizcrilexlxx1505 So, not an ejection at all. In fact, to get the reactor out was practically a factory rebuild. Takes years. Hulls had greater structural limitations back then. It would have been even harder than it is now to accommodate such a feature. Really, if you think this was ever real, give an example.
ye, when ever I enter that debate I need to explain what hot and cold even means, and how it doesn't matter in a vacuum without stuff to be hot or cold. It doesn't matter in the same way at least.
The worst is when being in space is depicted as somehow causing frost to form on someone. As if space is not only cold in a conventional sense, but also somehow has sufficient humidity for ice deposition.
As a submariner I saw this and just HAD to click on this video. Thanks for the insightful scenario! Now I have a one-up on my shipmates if we ever get into a conversation of the environments our sub could survive in. (I must admit, temperature is never something I’d have considered)
There was a documentary on History channel (if you can call show on that channel a documentary) on what would happen if huge planet like Youranus would get close to Earth. The one thing is that it would suck the oceans along with stuff like submarines into space. They described problem with submarine in space exactly as author of this video.
Ex US Navy nuclear plant operator here, first thing I though of was "Well, not very long without water for the turbine condensers". It would probably (horrifically) more likely be that the condenser rupture disks fail and the engine room is filled with superheated steam killing everyone inside in a mater of minutes, after a few seconds the electrical turbines trip causing critical loads to move onto the motor generators and quickly chew through the batteries until a loss of all power scram occurs. Depending on how high reactor power was at the time of the scram the pressure relief valves will probably not pop for a few minutes to hours. It wont be until the pressurizer tank goes empty (Oops, we're in space! PWR reactors won't like that, nobody tell them they're in micro gravity!). Not that maters since now everyone outside of engineering is in a pitch black tube relying on flashlights to see and the ventilation systems have failed along with the potable water pumps that pump water from the storage tanks located in engineering. . . . Being insta killed by steam seems like a kinder fate that dying of dehydration and slowly suffocating. I only have one question; how did that submarine get up in space in the first place? 🤣
@@CasabaHowitzer Man, I'd hate to have that job. Do I at least get whole life in the benefits package? (Would probably make more sense if they armed it remotely on the descent, but I guess a man's gotta do what a man's gotta do.)

Under Project Orion, the proposal to have spacecraft propel themselves via a sequence of nuclear bomb detonations (Yes!) it was suggested that spacecraft could be built in naval yards, on the grounds that it didn't much matter how heavy a spaceship is if it's propelled by exploding nukes.
I work at a shipyard that repairs submarines, and a coworker asked "why haven't we combined a submarine and a spaceship?" I replied "same reason we haven't combined airplanes and snowplows". We ended up having an AI art generator make us pictures of combination Submarine/spaceships. Not gonna lie, they go hard. Funny this video popped into my feed.
I have a story called The Water Thieves where massive (500 km dia) spaceships come and lower into the seas and steal water. They capture a nuclear submarine by accident and the story follows the sub, encased in ice, as it travels to an alien planet. This video was very informative. I got most of the tech description correct in the novel.
I doub tit would freeze that fast if they had this kind of volume. With radiatin only, a sphere of 100km in diameter of sea (salted) water would stay liquid for months\years, surface will freeze, but that would reduce radiation.
As other commenters already posted, go and watch Futurama. Spaceships dont belong underwater. They are built for the athmosperic pressure of space, so virtually 0. To build a spaceship that can withstand the pressure of oceans you would have to use way more energy than efficient. Simply to speak, you would build a spaceship that carries some type of submarine. Or you would just evaporate the water, collect the steam and clean it from air. Or giant tube that suck the water into the spaceship. But please dont let them dive ;) A spaceship that big would also create problems on earth. Its smaller than the moon but the moon is not very dense and theremore not much mass. So the spaceship could be easily half of the mass of the moon (without any calculations). A landing on earth would create massive disasters around the world. Just a quick visit with such a giant ship would kill millions of people. Just sayin' ^^
This video gives me such Gloryhammer vibes. For those who don’t know, Gloryhammer is a British power metal band, and one of their songs “Hootsforce” takes place on a submarine in space.
Interesting side note, in order to deorbit, you'd want to burn your -engines- missiles in the opposite direction of travel, not down towards the Earth. It's your speed around the planet that is keeping you in orbit. So in order to deorbit, you reduce your speed and let gravity do this rest.
@@sultanofsickHm? I mean, if you apply *enough* force for a long enough time, sure, but isn’t the point of the top level comment that you need substantially less delta v to deorbit if you apply it in the direction opposite your current motion, than you would need if you apply your delta v in a downwards direction? Hm, I wonder, if you apply a rather small downward force for arbitrarily long times, does that guarantee eventually de-orbiting? I think, perhaps not, if the force is small enough. Like, if based on your current position and momentum, you would be in a perfectly circular orbit if the body you are orbiting were a bit more massive, then if the additional downward force is the difference between what the gravity would be if the bode were that slightly larger mass, and what it is in reality, then you would continue on that circular orbit. And, if you take a perfectly circular orbit, but reduce the mass of the body being orbited slightly, that won’t cause the orbiting body to no longer be in orbit. So, for some possible initial orbits, there is some amount of force downward which if it starts getting consistently applied downward, will not cause the orbiting body to ever deorbit. On the other hand, if you apply a force in the opposite direction of motion, you *will* decrease the velocity, and eventually deorbit, even if, if the force is very small, it might take a long time.
This is solved by lighting the one farthest from the sub's center of mass first, very briefly, which will cause the sub to rotate. Per the drawing, the missile closest to the aft may or may not be on the other side of the center of mass, depending on whether or not the power source is disassembled and chucked out due to being a hazard, and how heavy the missiles themselves are. If it IS on the otherside of the center of gravity, then lighting it for awhile (probably longer since it appears closer to the center) would allow the sub's facing to change such that lighting all the missiles simultaneously would create the exact course correction you're mentioning. Otherwise, you could just time the ignition for very short intervals to occur as the sub is rotating through space, and only ignite when the engines are facing the otherway. This all assumes the missiles *can* be turned off and back on. If they can't, then if you just start the one furthest from the center of gravity first, and then light the others at the right time, the sub will start flying in a circle, where the center of the circle is still mostly going in the original direction the sub was, but also, doing so much slower than originally. Because gravity follows an inverse cube, the sub will always need more energy to get farther away from the Earth than closer to it, so as it flies in this circle, the circle will accelerate toward's the Earth's surface. It won't be an ideal re-entry, and will cause the sub to absolutely be tumbling when it hits the atmosphere, causing it to break apart much more rapidly than it would otherwise, and be a generally much more difficult to survive situation. Cons: This is less survivable for the crew than most of the other scenarios. Pros: This will result it less debris actually striking land, since it'll break up into smaller pieces earlier during re-entry. Also, it is still more survivable than if the warheads are detonated.
@drdca8263 I think that small consistent downwards force would effectively end up making your orbit projections look like they are hoola hooping around the planet. Maybe this concept would be useful if geostationary gets extremely full, you could effectively get multiple layers with active support geostationary
Orbital mechanics are pretty unintuitive to me. Would thrusting towards the planet just make you go faster? Assuming no atmosphere. Would thrusting outwards make you go slower?
Former submarine guy reporting. Thanks for the video. I will admit to one thing: the nuclear techs, machinists, and reactormen (at least, the ones on MY boat) have legitimately figured out a workaround for most of these presented problems, including the water and oxygen issue and the heat problem. However, I'm not allowed to explain how they figured out the workaround because it involves some other classified equipment, as well as explaining the positioning and placement of certain internal tanks that you don't need to know about. However, you've nailed it when it comes to stock submarines. 👍
If you are really a former submarine guy, you are missing an assumption that made your classified technology work in the water but which does not work in space. There is no way to destroy the heat that is being produced by the reactor. Obviously, fridges also don't eliminate heat but radiate it off outside the fridge. Even if pumping cooling water into and out of the sub is not an option, the hull being in water allows to get rid of heat much faster than if the sub is in outer space. The surface area of a sub isn't sufficiently large to radiate all that heat off into a (near-)vacuum. Huge radiators for space stations etc. exist, but subs don't have them and to radiate off anything close to 50MW of heat, these radiators would have to be gigantic.
Well let's see. You could use the potassium superoxide from fire suppression in the CO2 scrubbers. There's also chlorate and peroxide that could be used for oxygen reactions. Connect the reactor secondary glycol loop through a skydrol loop into a ballast tank and slowly boil it off into space. There's also the gray and black water tanks when ballast runs out. My biggest concern would be internet access of course, you'd have to duct tape up a JIM suit and send a guy out to put up a new antenna to get enough bandwidth for gaming
In the Looking Glass series by John Ringo and Travis Taylor, humanity finds a warp drive from an extinct race, and uses it to build our first interstellar ship, by converting a submarine. They discuss the cooling issue, and deal with it by storing heat in solid glass bars attached to the underside of the ship, and they periodically have to stop and "chill" bu extending thr glass rods to let them radiate in space for a few hours. Good book series. Highly recommend it to any sci fi readers
In Gilpin's Space by Reginald Bretnor, a new kind of space drive is invented and it is made clear that *only* submarines or similar vessels are suitable for installation. This is more of a "shift into a quasi-dimension" thing (it's revealed later that every ship transitions into its own independent space) so we can handwave away the heat dissipation problem :)
You are wrong in some ideas 1. Submarines are anything, but airtight. In fact, it is that massive pressure while underwater which makes them waterproof. When they are on surface, they leak regularly and water pumps are usually running to keep their bottom dry. Modern submarines are not leaking like those from WW2, but still, there are thousands of bolts, welds and joints in modern nuclear submarine. If few of them are leaking, it does not mean, that submarine would be dismantled and those faulty connections repaired. They are built in such way, that external pressure would keep them together, even if all connections would fail. But this exact design feature revert to design flaw, when there is not external, but internal overpressure. So submarine would lose livable air pressure pretty quickly, in matter of hours or even minutes. 2. CO2 scrubbers on submarines would not work in microgravity. First, they need water (cooling) for their function, second submarines rely on gravity for airflow into these scrubbers. But there is almost no gravity in microgravity so they would not work. But truth is, that air would be out much faster, than CO2 buildup itself to dangerous concentrations. 3. Temperature in space, especially on Earth orbit is mainly about massive solar power at Earth orbit. It is 1366W/m2. So if submarine, which is also black, would face sun by one of its side, power recieved would be in megawatts. And temperature of sun facing hull would quickly rise to 120°C! And because submarines has metallic interior and little to no heat insulation (especially american ones), this temperature would be on internal walls in submarine. This is why it is problem to keep spacecrafts cool and why they have silver or gold coating. And on dark side of Earth it is not so cold, because Earth itself radiate like 460W/m2, so this significantly reduces cooling ability of radiation cooling. 4. Naval nuclear reactors are nowhere near 50% efficiency you suggested, In fact, it is 15-25% and its inefficiency in comparison with civilian reactors (30-43%) is due necessity to quickly changing power output. 5. 200MW nuclear reactor would heat interier of submarine much faster. Let say, that submarine weights 8000 tons of steel, steel has heat capacity 420J/kg, so you need just 3,36GJ to increase temperature of all submarine mass by 1 degree. 200MW reactor would accumulate that energy every 17 seconds and do not forget about suns addition. In less than 10 minutes temperature of mass of submarine would be over 60°C, which would be deadly. 6. Your calculation of Trident missile push to Ohio class submarine is slightly off, accoridng my calculation knowing specific impulse and mass of propellant in that missile and dry weight of Ohio class, it is 8m/s per missile. But in the end, it combined push from all missiles is enough to reentry in both values. 7. I am pretty sure, that submarine would survive reentry pretty intact. First thing it will semistabilise in backward direction (propeller in front of flight) because of its shape. Second thing, it is massive steel construction and many of them protected by echelon tiles coating. So many things for ablative cooling. And last thing, when massive human objects are falling from orbit, they survive surprisingly intact and they are constructed from thin aluminium and/or lithium sheets. So 5cm thick steel hull should survive pretty easily. But this leads to conseqeunt problem - terminal velocity of such submarine would be too high for jumping of it. Accordion my "calculation" for Ohio class it would be at 4000 meters at least 1200 m/s, so basically borderline hypersonic. Even at supersonic speed is impossible to jump out of flying object without protective suit and rocket chair.
This was great! You and the video only left out the part where launching an entire nuclear submarine into space would be ASTRONOMICAL. Even if they took the propulsion unit out and added wings to land or whatever
@@NM-yu3fc Not only astronomical price, but also technically not possible. Not on chemical rocket engines. To get Virginia class submarine into space, which weights "only" 6500 tons, you would need to attach to her 40-50 SHS (Superheavy and Starship in expendable version). Something like that is "Kerbal space program" wizardy definitely not possible with out technology and probably impossible due physical limitations of real world. In my opinion, if we will ever build such massive (in terms of weight) spaceships, it will be in space and they will be using fusion power for energy and propulsion. So basically "Expanse series" level technology and definitely not in this century.
@@tomascernak6112 it's a completely unreal scenario, agreed. I just liked your points on it, and noticed nobody pointed out that you couldn't launch something that heavy at one time in the first place 👍

3:46 I like how its speed is measured in knots because it's a ship, completely disregarding that it's a) in space, b) falling (or would it be sinking?), and c) no longer a cohesive vessel but rather a scattered collection of former submarine parts. (Note: I tried to find out what unit is used to measure the speed at which submarines dive by looking up "submarine dive speed", but I couldn't find a single helpful result)
The total thermal output (or close to it) of the nuclear reactor would need to be radiated out of the submarine, no matter how efficiently the reactor converts it to electricity, since the electrical power will itself eventually be converted to heat mostly if not entirely within the confines of the sub. Exceptions might be things like radio broadcasts. Point being that the efficiency aside isn't important. Also the lack of cooling water would cause the reactor to cease functioning properly in short order. Still a fun thought experiment though!
The question isn't whether the heat would _eventually_ radiate away, it's whether the heat would radiate away _faster than it built up._ If a hundred megawatts of heat are generated, radiating a dozen doesn't do much to help. Of course, radiant heat dissipation increases with temperature, but A. that's only true of the hull temperature and B. that doesn't affect the calculations much until the crew has been cooked.
Something to remember, submarines have ballast tanks in any basic design. They're already designed to hold water, water is also good for blocking that pesky radiation.
Water could not only mitigate radiation but also the temperature between the sun exposed side and the one in the shadow. Of course, if the sub moves away from the sun it may freeze and likely damage the tanks.
@@roccosfondo8748 Yeah, but unlike in the ocean there is nowhere for the submarine to get more water. Once the water in the tanks is heated up by the reactor which inevitably would happen, the water would be unless at cooling anything, and would only to continue to heat up with the rest of the sub.
@@horationelson1840 agreed with that. Probably some massive radiator would be necessary in order to dissipate the heat as radiating energy. I believe that they have radiators in the ISS. Now, I don't know what is their efficiency ratio therefore I have no clue about how much surface it may be needed for a nuclear reactor.
The reality is that all submarines that carry nuclear missiles are also nuclear powered, which increases the confusion. It's a coincidence due to the fact that nuclear missile subs should be always at the ready, and loiter for months in specific places in the ocean. There are nuclear-powered submarines that DON'T have ICBMs, though: the attack subs that only carry torpedoes to hunt other vessels, or do other stuff like signal reconaissance.
Cooling in space is a really cool topic! Within our atmosphere, we usually cool things either by getting it in contact with a cooler substance (like aircooling, where we pass heat to the surrounding air) or by evaporation (like sweating). Neither of these things work well in space. There is nothing around you to dump heat into, and water is hard to get by. You can try to focus the heat in a physical object and then dump that overboard, but that's obviously limited by your carrying capacity and prohibitively expensive. So the only thing that remains is to passively emitt heat as radiation. Everything emitts heat this way (which is why thermal imaging systems work), but it is an excruciangly slow process compared to our regular cooling methods. This is why spacecraft have to be very carefully designed to not produce or absorb too much heat (reflective or white surfaces help) and to have large surface areas that are well suited to emitting heat without getting heated up by the sun themselves.
Not just radiation, but conversion, efficient and layered heat-to-electricity, for example. And electricity can be used to move heat. In space, a person with nothing on but a respirator, would overheat.
So if I remember correctly, I think the DY class of ships in Star Trek were basically remodeled nuclear submarine hulls with a bunch of pods attached to them, then launched into orbit.
And I can guarantee that the writers didn’t put that much thought into it, and that the people who built the DY series props in Space Seed just kitbashed an off the shelf submarine model they bought at a toy store.

I especially enjoyed the sentence "If the ballistic missiles carried by a nuclear sub were placed in the tubes backward."
DESTIN!
Of course, igniting the rocket engines that close to the hull might SLIGHTLY exacerbate the heat buildup problem. 😂 You probably know this, but even in the cold cold ocean, the missles are launched out of the tubes by steam before the engines kick in.
Which brings up the inevitable followup question, how much bracing would be required to keep the backwards facing rocket designed to go very far up and then sideways from creating a new hole on the other side of the sub or causing a big mess inside.
Thats the important question we need answered.
Loved your “deep dive” into the submarine systems on your channel, Dustin!

So disabling the missile's warheads is of course necessary. If you want to survive the reentry, you might also need to eject the submarine's reactor too. It won't explode, but it will crack apart and spew uranium everywhere in the vicinity, so that's kind of bad.
@@JLG331 given there are also a bunch of nukes on board, that might be a pointless endeavor. Even if the missiles were perfectly disarmed so they wouldn't go off on impact, that's still a whole lot of uranium going up in smoke. Plus the fuel lockers for the reactor.

@@Ydrakar Do you realize how much that is? I mean, that's more than a few hundred thousand tons of air. And also, yeah, Helium floats because it's light. And a few hundred thousand tons is not light. It's, well, a few hundred thousand tons. The question is, how much volume will that much helium take, even maximally pressurized (which will technically make it solid).
Dive dive dive
@@CapnBlud The helium doesn't float because it is light, it floats because it is less dense than air. A "few hundred thousand tons" of helium would still float and a gram of metal would not. The problem is the volume, like you said. Besides, if you could potentially float, you wouldn't reach outer space because things float because they are less dense than air. As the air pressure reduces, that effect would reduce as well. In that case you need another external force to give you speed to make you go into orbit. Otherwise you would never leave the atmosphere

I could be wrong, but It’s my understanding that non-conventional bombs like that would need to be detonated with a trigger mechanism. Even the old style of “bullet” atomic weapons where the fissile material was essentially encased in an explosive sphere to cause the chain reaction would occasionally be a dud due a slight imbalance in the explosive. The main concern with them falling out of the air is the fissile material would be flung everywhere. This guy sounds like he knows what he’s talking about though.

@@_P2M_So you knew that the reactor would explode before the entire sub gets so hot that it grills the crew?
I would have to wonder just how airtight a sub would be. The seals are designed to have positive (by a large amount) external pressure, and not negative pressure. So to me the seals are "pointing in the wrong direction". It might leak like a sieve in space.
I was waiting for this to be mentioned, but surprisingly it wasn't.
There'd likely be some leakage, but I wouldn't expect it to be huge, primarily because the individual compartments inside a sub are designed to be water-tight both-ways, in case a compartment floods.
Like the doors and bulkheads between the missile deck and the engineering deck will keep the engine room pressurized if the missile deck floods, but will also keep the missile deck pressuized if the engine room floods.
And it's not like the hull requires pressure to be watertight either, else a sub would leak while on the surface.
Plus all the external hatches are redundant, if not actual airlocks; we wouldn't want a single failed hatch to sink a sub.
Yeah, that was my thought as well. You could possibly seal off areas that are particularly bad and save the crew from decompression but the ballast tanks are almost certainly going to leak, likely causing significant spin. I also doubt you can seal off the tertiary coolant feed tank for the reactor.
I think that while seals can be biased in one direction, unless they're deliberately designed to be uni-directional (and there'd be little reason to do that), they'll still have some resistance the other way. And because of the magnitude of difference between the negative pressure of 1 atm > 0 atm and the positive pressure of a couple hundred meters of water, the seal would have to be like 100x worse in one direction than the other for it to be an issue. I think it's more likely that the 'bias' of the seals would be like near 2:1, not 100:1
One of the ways they test the water tight integrity of a submarine before diving is to overpressure the boat and hold that pressure long enough to see if there's any leakage. I'm pretty sure they don't go all the way up to two atmospheres but the principle is the same. The seals might not be able to take as *much* pressure outward instead of in, but they can take at least that much.

So now I am confused about why the crew on Apollo 13 got so cold. Were they shielded from the sun and unable to reduce the amount of heat radiated away?
@@JaniceinOR As far as i remember reading, the issue was that the outside of the craft was very well isolated, so while it did heat up significantly on the surface, barely any of the heat made its way inside.
On the other hand, they had no possibility of heating the craft up and no way to really get rid of the moisture that was building up inside. Given that they also spent a significant amount of time outside of the suns reach, they struggled to keep the craft warm as the men alone were not enough to keep it warm.
You also have to keep in mind that there was still a lot of warmth cooled down by the crafts cooling systems, otherwise the electrical devices would have overheated within hours.
So it was an issue of freezing but having the systems to make it home, or being warm but unable to come home.
I might misremember though.
BTW Oxigen not included works in a correct way with vacuum and temperature.

Ah cool. Thanks for sharing!@@willythemailboy2
In addition to Willy's brilliant reply. Remember that subs are designed to work on the surface of the water too. If they relied on the mountain of outside pressure from the water at 100m depth, they'd leak and thus sink whenever they surfaced.
@@MGSLurmeyThat's not how that works. Many directional Seals are almost like a one way valve. When there is no pressure on them they have a small "spring force" holding them tight against very low pressures. As the pressure increases, it needs to be squeezed against the sealing surface increasingly hard to seal. The increasing pressure is used to provide the sqeezing, so the higher the pressure the better the seal. Put the pressure on the wrong side of the seal however and you lift the seal away from the sealing surface, and let everything through.
subs are also compartmentalized thus if one section floods they need the rest is save from the pressure. Thus it should be both ways.

The heat issue is the reason that the original design for Discovery in "2001: A Space Odyssey" had huge triangular wings on both side of the ship. They were heat radiators. Stanley Kubrick decided to delete them, which is why the final design for Discovery is basically a ball on the end of a stick. Kubrick thought the audience would be confused by wings on a spaceship, and he was probably right. But in reality, you would need those big radiator surfaces to get rid of the waste heat from the nuclear reactor.
If you read Arthur C. Clarke's novel version of "2001," you'll see that he describes the original design. In the book, Discovery is shaped like a giant arrowhead.

Players founds the leaks via incense and followed the smoke trails, which made me very proud. Also instead of maneuvering using missiles, one of them put on a space suit, stood on the sub's hull and fired guns. For hours. Not a great change in velocity, but they didn't need much.

Ex US Navy nuclear plant operator here, first thing I though of was "Well, not very long without water for the turbine condensers". It would probably (horrifically) more likely be that the condenser rupture disks fail and the engine room is filled with superheated steam killing everyone inside in a mater of minutes, after a few seconds the electrical turbines trip causing critical loads to move onto the motor generators and quickly chew through the batteries until a loss of all power scram occurs. Depending on how high reactor power was at the time of the scram the pressure relief valves will probably not pop for a few minutes to hours. It wont be until the pressurizer tank goes empty (Oops, we're in space! PWR reactors won't like that, nobody tell them they're in micro gravity!). Not that maters since now everyone outside of engineering is in a pitch black tube relying on flashlights to see and the ventilation systems have failed along with the potable water pumps that pump water from the storage tanks located in engineering. . . .

I work at a shipyard that repairs submarines, and a coworker asked "why haven't we combined a submarine and a spaceship?" I replied "same reason we haven't combined airplanes and snowplows". We ended up having an AI art generator make us pictures of combination Submarine/spaceships. Not gonna lie, they go hard. Funny this video popped into my feed.
Space Battleship Yamato kinda rocks, though :P
Screw the space submarine, I wanna see a snowplow-airplane combo now
@@giin97 but Yamato isn't really a submarine? I think the New Nautilus (Exelion) submarine from Secret of Blue Water will fit better.
I have a story called The Water Thieves where massive (500 km dia) spaceships come and lower into the seas and steal water. They capture a nuclear submarine by accident and the story follows the sub, encased in ice, as it travels to an alien planet. This video was very informative. I got most of the tech description correct in the novel.
When and where will the book be available?
Not knowing of their motivation. There are several moons in the solar system with more water and no one there to defend it. Did they already take it?
I doub tit would freeze that fast if they had this kind of volume. With radiatin only, a sphere of 100km in diameter of sea (salted) water would stay liquid for months\years, surface will freeze, but that would reduce radiation.
As other commenters already posted, go and watch Futurama. Spaceships dont belong underwater. They are built for the athmosperic pressure of space, so virtually 0. To build a spaceship that can withstand the pressure of oceans you would have to use way more energy than efficient. Simply to speak, you would build a spaceship that carries some type of submarine. Or you would just evaporate the water, collect the steam and clean it from air. Or giant tube that suck the water into the spaceship. But please dont let them dive ;)
A spaceship that big would also create problems on earth. Its smaller than the moon but the moon is not very dense and theremore not much mass. So the spaceship could be easily half of the mass of the moon (without any calculations). A landing on earth would create massive disasters around the world. Just a quick visit with such a giant ship would kill millions of people. Just sayin' ^^
@sleepingcity85 are you sure?
XKCD?!? On TH-cam?!? With fun explainer videos?! Yes!!!!
This video gives me such Gloryhammer vibes. For those who don’t know, Gloryhammer is a British power metal band, and one of their songs “Hootsforce” takes place on a submarine in space.
"If you sit in this spot just right" has the same vibe as "if you jump right before the plane crashes, you'll survive"
Just need to find a parachute on a submarine first.
Interesting side note, in order to deorbit, you'd want to burn your -engines- missiles in the opposite direction of travel, not down towards the Earth. It's your speed around the planet that is keeping you in orbit. So in order to deorbit, you reduce your speed and let gravity do this rest.
I mean, you CAN do it by pointing straight down. The spacecraft will in fact not be orbiting anymore if you do that.
@@sultanofsickHm? I mean, if you apply *enough* force for a long enough time, sure, but isn’t the point of the top level comment that you need substantially less delta v to deorbit if you apply it in the direction opposite your current motion, than you would need if you apply your delta v in a downwards direction?
Hm, I wonder, if you apply a rather small downward force for arbitrarily long times, does that guarantee eventually de-orbiting?
I think, perhaps not, if the force is small enough.
Like, if based on your current position and momentum, you would be in a perfectly circular orbit if the body you are orbiting were a bit more massive, then if the additional downward force is the difference between what the gravity would be if the bode were that slightly larger mass, and what it is in reality, then you would continue on that circular orbit. And, if you take a perfectly circular orbit, but reduce the mass of the body being orbited slightly, that won’t cause the orbiting body to no longer be in orbit.
So, for some possible initial orbits, there is some amount of force downward which if it starts getting consistently applied downward, will not cause the orbiting body to ever deorbit.
On the other hand, if you apply a force in the opposite direction of motion, you *will* decrease the velocity, and eventually deorbit, even if, if the force is very small, it might take a long time.
This is solved by lighting the one farthest from the sub's center of mass first, very briefly, which will cause the sub to rotate. Per the drawing, the missile closest to the aft may or may not be on the other side of the center of mass, depending on whether or not the power source is disassembled and chucked out due to being a hazard, and how heavy the missiles themselves are. If it IS on the otherside of the center of gravity, then lighting it for awhile (probably longer since it appears closer to the center) would allow the sub's facing to change such that lighting all the missiles simultaneously would create the exact course correction you're mentioning.
Otherwise, you could just time the ignition for very short intervals to occur as the sub is rotating through space, and only ignite when the engines are facing the otherway.
This all assumes the missiles *can* be turned off and back on. If they can't, then if you just start the one furthest from the center of gravity first, and then light the others at the right time, the sub will start flying in a circle, where the center of the circle is still mostly going in the original direction the sub was, but also, doing so much slower than originally. Because gravity follows an inverse cube, the sub will always need more energy to get farther away from the Earth than closer to it, so as it flies in this circle, the circle will accelerate toward's the Earth's surface. It won't be an ideal re-entry, and will cause the sub to absolutely be tumbling when it hits the atmosphere, causing it to break apart much more rapidly than it would otherwise, and be a generally much more difficult to survive situation. Cons: This is less survivable for the crew than most of the other scenarios. Pros: This will result it less debris actually striking land, since it'll break up into smaller pieces earlier during re-entry. Also, it is still more survivable than if the warheads are detonated.
@drdca8263 I think that small consistent downwards force would effectively end up making your orbit projections look like they are hoola hooping around the planet.
Maybe this concept would be useful if geostationary gets extremely full, you could effectively get multiple layers with active support geostationary
Orbital mechanics are pretty unintuitive to me. Would thrusting towards the planet just make you go faster? Assuming no atmosphere. Would thrusting outwards make you go slower?
-Is space hot?
-Of course it is, where do you think we get pineapples from!?
Under the sea. Sometimes sponges maker their way inside before the pineapple is harvested.
Dave's Syndrome 🤣
I'm stuck at work not doing much but scrolling youtube lately, thanks for putting out something genuinely interesting!
I truely love having a thought (like "what about reentry?" ) and then you read my mind an answer that exact sub-question.
(*SUB*-question)😀
Former submarine guy reporting. Thanks for the video. I will admit to one thing: the nuclear techs, machinists, and reactormen (at least, the ones on MY boat) have legitimately figured out a workaround for most of these presented problems, including the water and oxygen issue and the heat problem. However, I'm not allowed to explain how they figured out the workaround because it involves some other classified equipment, as well as explaining the positioning and placement of certain internal tanks that you don't need to know about.
However, you've nailed it when it comes to stock submarines. 👍
If you are really a former submarine guy, you are missing an assumption that made your classified technology work in the water but which does not work in space. There is no way to destroy the heat that is being produced by the reactor. Obviously, fridges also don't eliminate heat but radiate it off outside the fridge. Even if pumping cooling water into and out of the sub is not an option, the hull being in water allows to get rid of heat much faster than if the sub is in outer space. The surface area of a sub isn't sufficiently large to radiate all that heat off into a (near-)vacuum. Huge radiators for space stations etc. exist, but subs don't have them and to radiate off anything close to 50MW of heat, these radiators would have to be gigantic.
This is the most astounding 5 sentences I've ever read.
I mean it unironically when I say, "When you get your sub into space, I WANNA GO!"
Well let's see. You could use the potassium superoxide from fire suppression in the CO2 scrubbers. There's also chlorate and peroxide that could be used for oxygen reactions. Connect the reactor secondary glycol loop through a skydrol loop into a ballast tank and slowly boil it off into space. There's also the gray and black water tanks when ballast runs out. My biggest concern would be internet access of course, you'd have to duct tape up a JIM suit and send a guy out to put up a new antenna to get enough bandwidth for gaming
You could have stopped at 2:57, but everything after that point is why I love these
One of the best animated videos ❤🤍
In the Looking Glass series by John Ringo and Travis Taylor, humanity finds a warp drive from an extinct race, and uses it to build our first interstellar ship, by converting a submarine. They discuss the cooling issue, and deal with it by storing heat in solid glass bars attached to the underside of the ship, and they periodically have to stop and "chill" bu extending thr glass rods to let them radiate in space for a few hours.
Good book series. Highly recommend it to any sci fi readers
In Gilpin's Space by Reginald Bretnor, a new kind of space drive is invented and it is made clear that *only* submarines or similar vessels are suitable for installation. This is more of a "shift into a quasi-dimension" thing (it's revealed later that every ship transitions into its own independent space) so we can handwave away the heat dissipation problem :)
I was digging through the comments before I wrote basically what you did. Glad that I am not the only one who saw this and thought of that series.
Gotcha, our Sub Space Marine is to remove the Torpedo detonators & add air conditioners
Hootsforce arise!
I knew that this comment would be somewhere lmao
"In a submarine, beneath the seas
Of Achnasheen, we remain unseen
But now the time, has come to rise
Ascend into the skies!"
YES!!!
I have been wondering about this ever since listening to Hootsforce!
For the eternal glory of Dundee
I'm so putting this on my bucket list!
0:07 my initial thought was "That nuclear reactor is going to get extra spicy, fast".
You are wrong in some ideas
1. Submarines are anything, but airtight. In fact, it is that massive pressure while underwater which makes them waterproof. When they are on surface, they leak regularly and water pumps are usually running to keep their bottom dry. Modern submarines are not leaking like those from WW2, but still, there are thousands of bolts, welds and joints in modern nuclear submarine. If few of them are leaking, it does not mean, that submarine would be dismantled and those faulty connections repaired.
They are built in such way, that external pressure would keep them together, even if all connections would fail. But this exact design feature revert to design flaw, when there is not external, but internal overpressure. So submarine would lose livable air pressure pretty quickly, in matter of hours or even minutes.
2. CO2 scrubbers on submarines would not work in microgravity. First, they need water (cooling) for their function, second submarines rely on gravity for airflow into these scrubbers. But there is almost no gravity in microgravity so they would not work. But truth is, that air would be out much faster, than CO2 buildup itself to dangerous concentrations.
3. Temperature in space, especially on Earth orbit is mainly about massive solar power at Earth orbit. It is 1366W/m2. So if submarine, which is also black, would face sun by one of its side, power recieved would be in megawatts. And temperature of sun facing hull would quickly rise to 120°C! And because submarines has metallic interior and little to no heat insulation (especially american ones), this temperature would be on internal walls in submarine. This is why it is problem to keep spacecrafts cool and why they have silver or gold coating. And on dark side of Earth it is not so cold, because Earth itself radiate like 460W/m2, so this significantly reduces cooling ability of radiation cooling.
4. Naval nuclear reactors are nowhere near 50% efficiency you suggested, In fact, it is 15-25% and its inefficiency in comparison with civilian reactors (30-43%) is due necessity to quickly changing power output.
5. 200MW nuclear reactor would heat interier of submarine much faster. Let say, that submarine weights 8000 tons of steel, steel has heat capacity 420J/kg, so you need just 3,36GJ to increase temperature of all submarine mass by 1 degree. 200MW reactor would accumulate that energy every 17 seconds and do not forget about suns addition. In less than 10 minutes temperature of mass of submarine would be over 60°C, which would be deadly.
6. Your calculation of Trident missile push to Ohio class submarine is slightly off, accoridng my calculation knowing specific impulse and mass of propellant in that missile and dry weight of Ohio class, it is 8m/s per missile. But in the end, it combined push from all missiles is enough to reentry in both values.
7. I am pretty sure, that submarine would survive reentry pretty intact. First thing it will semistabilise in backward direction (propeller in front of flight) because of its shape. Second thing, it is massive steel construction and many of them protected by echelon tiles coating. So many things for ablative cooling. And last thing, when massive human objects are falling from orbit, they survive surprisingly intact and they are constructed from thin aluminium and/or lithium sheets. So 5cm thick steel hull should survive pretty easily. But this leads to conseqeunt problem - terminal velocity of such submarine would be too high for jumping of it. Accordion my "calculation" for Ohio class it would be at 4000 meters at least 1200 m/s, so basically borderline hypersonic. Even at supersonic speed is impossible to jump out of flying object without protective suit and rocket chair.
Love the indepth explanation. Thank you!
This was great! You and the video only left out the part where launching an entire nuclear submarine into space would be ASTRONOMICAL. Even if they took the propulsion unit out and added wings to land or whatever
@@NM-yu3fc Not only astronomical price, but also technically not possible. Not on chemical rocket engines. To get Virginia class submarine into space, which weights "only" 6500 tons, you would need to attach to her 40-50 SHS (Superheavy and Starship in expendable version). Something like that is "Kerbal space program" wizardy definitely not possible with out technology and probably impossible due physical limitations of real world.
In my opinion, if we will ever build such massive (in terms of weight) spaceships, it will be in space and they will be using fusion power for energy and propulsion. So basically "Expanse series" level technology and definitely not in this century.
@@tomascernak6112 it's a completely unreal scenario, agreed. I just liked your points on it, and noticed nobody pointed out that you couldn't launch something that heavy at one time in the first place 👍
@@NM-yu3fc Yes, your point is correct. First thing is to get that submarine in orbit :-D
I assume, that narrator in video is thinking about scenario, where some magical being teleports that submarine in space instantly.
Yes it is a joke question, but surprisingly good for mental exercise too. i like scenarios and questions, which will torment our brain a little ;-)
I appreciate the very necessary thoroughness of this. Especially the part about turning off the detenators on the nuclear armed missles.
i like how when your starting to explain that space is warm the time on my phone suddenly hits 9pm which auto activates my eye safety feature thingy which makes the screen have a warmer tone of color

@BollywoodNewzz Bot
Surpringly entertaining channel which TH-cam’s algorithm has only just decided to show me. Fascinating. I subscribed.
3:46 I like how its speed is measured in knots because it's a ship, completely disregarding that it's a) in space, b) falling (or would it be sinking?), and c) no longer a cohesive vessel but rather a scattered collection of former submarine parts.
(Note: I tried to find out what unit is used to measure the speed at which submarines dive by looking up "submarine dive speed", but I couldn't find a single helpful result)
A submarine crew usually just uses feet per second (or meters per second) to describe a submarine's decent rate.
It's not a ship, it's a boat.
I loved this one. I also loved that Randal did the narration. :-)
The total thermal output (or close to it) of the nuclear reactor would need to be radiated out of the submarine, no matter how efficiently the reactor converts it to electricity, since the electrical power will itself eventually be converted to heat mostly if not entirely within the confines of the sub. Exceptions might be things like radio broadcasts. Point being that the efficiency aside isn't important.
Also the lack of cooling water would cause the reactor to cease functioning properly in short order. Still a fun thought experiment though!
The question isn't whether the heat would _eventually_ radiate away, it's whether the heat would radiate away _faster than it built up._ If a hundred megawatts of heat are generated, radiating a dozen doesn't do much to help.
Of course, radiant heat dissipation increases with temperature, but A. that's only true of the hull temperature and B. that doesn't affect the calculations much until the crew has been cooked.
wouldnt it be a closed system and recycle the water.
Funny, only after I wrote pretty much the same thing as you did I see your comment and youtube actually shows me mine immediately above yours.
Efficiency does matter. Work is being done by the electricity so.not all of the energy results in waste heat.
@@vanguard9067 No, that's not how thermodynamics works. Sooner or later, all the work-energy will also become heat.

2:22 Quite easy actually. Get a war thunder player to leak the documents 🤣
The real reason they don't have submarines in War Thunder.
I love how no one mentioned the submarine class being “Ohio” 😂
@@maxalon2479Why would they?
Something to remember, submarines have ballast tanks in any basic design. They're already designed to hold water, water is also good for blocking that pesky radiation.
The massive metal hull of a submarine is already pretty good at blocking radiation.
@@feuerling you make 3.3" more intimidating than most, papi 🥰
Water could not only mitigate radiation but also the temperature between the sun exposed side and the one in the shadow.
Of course, if the sub moves away from the sun it may freeze and likely damage the tanks.
@@roccosfondo8748 Yeah, but unlike in the ocean there is nowhere for the submarine to get more water. Once the water in the tanks is heated up by the reactor which inevitably would happen, the water would be unless at cooling anything, and would only to continue to heat up with the rest of the sub.
@@horationelson1840 agreed with that. Probably some massive radiator would be necessary in order to dissipate the heat as radiating energy. I believe that they have radiators in the ISS. Now, I don't know what is their efficiency ratio therefore I have no clue about how much surface it may be needed for a nuclear reactor.
i absolutely LOVE that you used the unit 'knots' to describe the speed of the crashed submarines debris
"I have an idea. How many parachutes does this submarine have?"
I finally watched your video and can sum up:
No one used the power of the hootsforce.
Okay, I actually learned something:
Nuclear submarines aren't submarine with nuclear rockets, but nuclear-powered submarines.
Often, they're both.
The reality is that all submarines that carry nuclear missiles are also nuclear powered, which increases the confusion. It's a coincidence due to the fact that nuclear missile subs should be always at the ready, and loiter for months in specific places in the ocean. There are nuclear-powered submarines that DON'T have ICBMs, though: the attack subs that only carry torpedoes to hunt other vessels, or do other stuff like signal reconaissance.
@@ayebraineand there are attack subs with nuclear Torpedos, even one that ain't even swimming any more

0:38 "Uh-O2!" god damnit, that made me chuckle
"It's hard to get good numbers on the efficiency of nuclear reactors in military submarines."
And you don't have to! All of the reactor energy will turn to heat and have to be radiated from the sub.
He overestimated the efficiency by a fair margin.
The sound effects are amazing
As a tax paying american citizen i demand that nasa focuses all its resources on this project. Im starting a petition.
Cooling in space is a really cool topic!
Within our atmosphere, we usually cool things either by getting it in contact with a cooler substance (like aircooling, where we pass heat to the surrounding air) or by evaporation (like sweating).
Neither of these things work well in space. There is nothing around you to dump heat into, and water is hard to get by. You can try to focus the heat in a physical object and then dump that overboard, but that's obviously limited by your carrying capacity and prohibitively expensive.
So the only thing that remains is to passively emitt heat as radiation. Everything emitts heat this way (which is why thermal imaging systems work), but it is an excruciangly slow process compared to our regular cooling methods.
This is why spacecraft have to be very carefully designed to not produce or absorb too much heat (reflective or white surfaces help) and to have large surface areas that are well suited to emitting heat without getting heated up by the sun themselves.
Not just radiation, but conversion, efficient and layered heat-to-electricity, for example. And electricity can be used to move heat.
In space, a person with nothing on but a respirator, would overheat.

So if I remember correctly, I think the DY class of ships in Star Trek were basically remodeled nuclear submarine hulls with a bunch of pods attached to them, then launched into orbit.
Yep, in early Star Trek lore the first interstellar ships were heavily modified submarines.
And I can guarantee that the writers didn’t put that much thought into it, and that the people who built the DY series props in Space Seed just kitbashed an off the shelf submarine model they bought at a toy store.

I appreciate that the speed of the submarine plummeting to the earth is being expressed in knots, as appropriate
