[@augustuslunasol10thapostle]

We should probably make proper civilian submarines

[@Riceball01]

Since modern military subs spends the majority of their time submerged, making them more visible wouldn't serve any useful purpose exit when transiting to and from port. In order to make a sub more noticeable in a practical manner, you don't make them more visible, you make them noisier since subs operating at their cruising depths are most often detected by the noise they make. So, as a result, military sub designers do what they can to make the sub as quiet as possible. Of course, that can be easily overcome by requiring all transport subs to have some of constantly transmitting noise maker built into them to act as a sort of audio warning beacon. But the problem with making subs noisier is that for it to work surface ships would all have to be fitted with some sort of passive sonar system to pick up the noise maker of these subs, something that civilian ships aren't generally equipped with.And water temperature and salinity would affect any the signal being produced by a noise maker and could maks it. It could be made electronic, but from I understand, electronic signals don't propagate very well through water, at least no radio signals. So depending on how deep these subs would travel, any sort of electronic transponder would largely useless.

[@mliittsc63]

The Germans transported a few items to Japan during WW2 by submarine. They also failed to transport some items because two of the subs were sunk. I gotta say that I do find it surprising that they didn't carry through on plans to obtain industrially important metals by submarine. They had plans to get them from South America, and IIRC they actually bought some of the metals. The metals were needed in relatively small amounts, and a submarine would have been practical. Of course, with the cracking of the enigma codes, the Allies would probably have gotten the details and stopped it. I think that was how the subs bound for Japan were sunk. Ultimately, cargo submarines are only useful in desperation, and unlikely to effect the outcome of a war. But I would bet the nurses evacuated from "Corridor" Island (Corregidor) were grateful for the use of regular subs as passenger subs. Can't help but wonder how many cargo subs would have been needed to maintain the forces on the Bataan peninsula. Losses would have been very high from IJN anti-submarine action.

[@captiannemo1587]

They did try transporting mercury... Frankly its absurdly expensive to ship by submarine.

[@gregorywright4918]

At the time, IJN anti-sub measures were mediocre - but the bigger problem would have been the unloading time (aside from the issues of lack of cargo subs and distance they needed to travel to secure bases with needed supplies). There were no naval bases on the Bataan peninsula, and few piers or sheltered coves, so it would have to be done off a beach or small cove, probably at night, with the threat of IJN destroyer or patrol boat interference. The Germans had a similar problem trying to supply Stalingrad by air after it was cut off, and their supply bases were much closer, and they had dozens of transport planes. Thousands of tons of supplies were needed, but they fell short.

A correction: The German WW1 cargo submarines were not U-Boats (i.e. combat submarines) with the torpedo tubes removed. They were purpose-built as cargo vessels. It was in fact the other way 'round. After the souring of relations with the US and its entry into the war, the cargo submarines, freshly out of a purpose, were converted to combat submarines. Specifically, their large size and impressive endurance were taken advantage of to convert them into the first long-range "cruiser" type submarines, intended to operate as far as the US East coast.

Barracuda class submarines were not cargo carriers. They were smaller and slower than the traditional fleet boats used by the US Navy during WWII, and were intended specifically to hunt other submarines using newly developed sonar and guided torpedoes (the conspicuous bulge on top of the bow that looks like a shorter second conning tower is a housing for sonar). They didn't work very well for that either, and were taken out of service relatively quickly.

[@nicolaspiganeau9621]

Actually, the real reason why there is no cargo subs and there will never be (at industrial scale I mean) is because of physics. A submarine needs to have the same average density as the seawater it is sailing in (1.026). Cargo in a container has a much lower density (remember: containers float). So a cargo submarine would need a huge amount of fixed ballast (typically lead) to keep it underwater and prevent the submarine to float. To get an idea, look at a filled container ship and imagine how much lead ballast you would need to add to drown the ship. That's the amount you will physically need to put in a submarine of the same size. No wonder it doesn't exist and never will.

[@drivewaystar6485]

The submarine becomes the "container" at that point. If a stripped out decomissioned war sub with all its weapons/ammunition/weapons systems removed and the weight of cargo replaced it what the difference? Yeah the balance may be an issue but i digress

@@drivewaystar6485 The point is, you need to be able to surface and dive, which means you need enough capacity in the ballasts to do both.

Many of the shipwrecks people would want to see are most likely a mass grave and should be left alone anyway.

He sees the scavenging for artifacts and damage done by the tours as disrespectful to the fact that nearly 2000 people died in the disaster. There would then be people who would want to go see other famous warship wrecks but those again are War Graves and should be left alone. It's a shame that so many in the pacific have been plundered for scrap metal. Other than the ethical concerns, there's the fact that diving to such extremes means you have to have one hell of a submarine, and then this simply becomes an exclusive thing for the super rich, and well I don't think those people should be allowed anywhere near something as hallowed as a fallen warship.

Well, sure, having them as a regular thing would not make much sense. But, just like we don't see much nuclear icebreakers, I think there are a few special cases where a nuclear cargo sub could make sense even if it is not as profitable as large cargo ships. In a few special shipping lanes, where you have to supply a coastal town or a base. It can double as a portable reactor in case there are problems with power supply. Countries like Russia, Canada, USA having one or two of those special purpose vessels - makes sense. They would have their regular shipping lanes above the arctic circle and have more than one simple task. When ever it is more beneficial to go under ice than over it, use it as a supply vessel. Otherwise, as a mobile power plant, science vessel, underwater construction crew... and why not, a tourist version? The cost of developing and building a very limited number of those subs would put the price per unit extremely high - but on the other hand, in the rare cases that you'd actually need a vessel like that, it could prove highly valuable indeed. Countries are not strangers to investing a lot to develop a highly specialized piece of gear that might not be commercial success, but still fulfills the critical role. There are some areas where cost is not really an issue, where you simply need to get something done. For example, some city in northern Alaska, or Siberia, gets hit by a storm, low on supplies, planes can't get to it, icebreakers ships not available or fast enough... you just load up your sub and send it as fast as possible under the ice to its destination to provide fresh supplies and attack its reactor output to the local power supply. Or, load up the entire science mission on it that can be housed inside its massive hull and be more mobile than the ship. Again, sub like that would not be something you'd find a need for in massive numbers, but a few for the biggest countries that can foot the bill - why not. Maybe even a joint development and have it serve as a quick response unit in time of need while paying itself off slowly over time with some basic commercial work.

@@fistofglory9304 Yes, they could do that as well, but in a pinch, any submarine US has would be able to do that. Problems with evacuation is that they usually don't happen in ports with deep enough a dock. In other words, there are not that many out there deep enough that would allow for a submarine to dock. That severely limits their use as an evac vessels. They could stop off shore and send in the boats, but if the weather does not allow the regular ship to come to the rescue, boats from the sub would have an ever worse time doing that. So yeah, in principle, they CAN add evacuation for certain places as their job (which is already highly situational), but honestly, that particular thing might never be needed in the lifetime of a sub, given how rare an occasion like that is.

[@grkvlt]

the explanation about why subs are less efficient due to displacement is wrong. it's because the surface ship displaces an amount of water equal to the weight of the cargo, whereas the sub must displace water equal to its entire volume - the cargo is generally less dense than water. the only thing this might make sense for us transporting liquids (like oil)

[@AlexandarHullRichter]

An interesting point that isn't really touched on is durability & safety. I'm not a huge fan of militaries, but in peacetime, I'd probably feel rather safe on a navy sub. They have large crews trained to handle any sort of breakdown (not just mechanical breakdowns, but things like partial hull failures as well), and navy ships are generally overbuilt so that they can get through actual combat and still make it back to base. By contrast, cargo ships...don't really have that level of safety. They're not maintained as well, as evidenced by a few of them actually just breaking up from hull fatigue. Their crews are much smaller, and much less extensively trained (except for navy vets in the merchant marine), and they have a particular constraint that tends to kill people: profit. I don't just mean that commercial ships have to be profitable to continue to operate, but that so many companies cut corners and sacrifice safety in the interest of profit.

[@peoplez129]

No submarine is designed to survive combat. A single hit on a submarine is basically game over. They aren't even largely meant for direct combat, but rather, for things like recon, a mobile weapons platform for sending missiles at far away targets, and defense of a fleet from other subs.

The stated downsides of a yellow submarine are mitigated somewhat. The design only needs to be strong enough for about 30meters to get under the wave effected zone, maybe a bit deeper for Ice caps but that is optional. Then the displace volume is higher, but the hull is not subjected to the complications and inefficiencies of the surface air interface, while submergered there is no bow wave for example. And if bobing around on the surface the tube is much stronger in torsion than an open top ship which is a major weakness in most large cargo ships when caught in large wave conditions.

Urgent enough that shipping by boat arround the arctic would be too slow. 3. Too heavy or fragile to be shipped by plane. 4. Valuble enough to justify high costs of shipping. And once you've narrowed down the shipping market based on these filters you're left with... nothing. ... And the rare case when there is something like this, the shipment is nowhere near frequently enough that anyone suggests investing a new mode of transport. Bummer.

Cargo submarines could still be useful to avoid pirates in places like the Strait of Malacca.

[@mohammadrifqisatriamas7311]

too shallow to do that, the shortest part of Malacca strait is only couple kilometers away, the average depth is only 25 meter

[@Boeing-I-hs2gj]

Well the drug cartels in America have found use with semi-submersible cargo Submarines.

[@adventureswithayan4925]

[@micfail2]

Not only is the shallowness an issue, the cost-effectiveness is still a problem. It's way cheaper to just hire half a dozen rednecks and give them rifles, just their presence will probably deter any pirates. Pirates are people too, they don't want to get shot so they'll wait for a softer target to come along.

[@virutech32]

you could just hire an armed escort ship or arm the cargo ship itself & hire security for a fraction of a fraction of the price of a cargo sub

I must say, cargo submarines actually sound like an interesting concept to me to put it short. 😀 And I'm also just waiting patiently for the remake of Boeing's New Large Airplane concept video, and the new video on British Airways mega triple decker concept from 1992. 😉

The Barracuda class submarine shown in the video is the post-WWII SSK version, a class of three boats, not the WWII-era boat.

[@shelbyseelbach9568]

Unnecessary complication will always fail. Self-explanatory. There is simply no need for a cargo vessel to be submergible. On another note, ingesting water won't cause drowning and is actually required to continue living. It is commonly known as drinking. INHALING water is what causes drowning. HILARIOUS!

They did a bit about the"Roller Boats" on ConeofArc. Look it up. Abject Failure. Think they did one on circular ships too.

[@murraymadness4674]

They could build semi-subs that can be even BIGGER than normal cargo ships, as they can hold more cargo under the water as well as on top. If I understand it, a cargo ship sinks from bad weather almost every month, that sounds really expensive failure, not what you want for a yellow submarine either.

[@fanta4897]

They do have one potential outside of military application. They'd be extremelly useful for nations that face sanctions. Following movements of submarines from port to port underwater would be extremelly hard even today.

Yellow Submarine

[@georgebulbakwa9017]

Never heard of a Corridor island in the Philippines. There is a Corregidor island though. Name roughly translates to what "customs" is today. The Spanish used the island as a customs checkpoint for the bay that led to the capitol of the then colony. The US then used the island as a military base. General Douglas McArthur was quartered there before he was evacuated by submarine. His "I shall return" speech was done in that fortress island.

[@Haematite]

we all live in a "yellow Submarine", at least we might if the sea levels rise by worst case scenario. and the Narco sub's are actually inspiring the DoD in regards to scout/sensor or limpet/midget designs

[@jackfrost2978]

the presented problem of ballast tanks, does not make sense to me. If the sub gets loaded up with lots of cargo. It is much heavier and would not need very large ballast tanks to get it under water. It would likely be designed with 2-3 storage areas that could work for storage or ballast tanks as needed.

[@goofycat676]

Good video but the picture of Germany was alt history I think

[@barrybend7189]

Do you have a free version of the cargo sub model? I'd love to use it as a base for a custom spacecraft model.

[@ThZuao]

Yellow submarine! I guessed right from the start of the video. However, the reason put into this video doesn't make much sense. I think I got a better one. Which also relates to why we don't have airships operating today. Though the displacement thing is undoubtelly a factor (I mean, they are literally limited by if they fit in certain places, like the Panama and Suez Canals), the real reason they're not economically viable is the ratio of air draft to wetted area, or the ratio of surface in contact with air to with water. This is relevant because friction with air creates much much less drag than with water. So much that they don't even care to design the structures above the hull line to be aerodynamic, meanwhile, every surface in contact with water in a sub has to be streamlined. Though strong winds have been known to knock containers off from time to time. And that ship that got stuck in the Suez canal was blown aground by wind. Maybe we'll get streamlined ships someday. That drag means more fuel burned, and given that those large ships can burn through 300 tons of HFO a day, fuel economy is of major concern.

[@JefferyBraun-m9u]

Submarine tankers were seriously considered as an alternative to the Alaska Pipeline. Also, Frank Herbert wrote a story about undersea "tug subs" that pulled oil around in gigantic blimp-like bags.

[@carlosmiguelteixeiraott3643]

Honestly though, I'm surprised I haven seen something like this in some comics or sci-fi work, because the idea is really cool, specially considering how often bases in space or stuff like Marvel's Helicarriers appear. Then again I guess Marvel and DC have Underwater people with Namor and Aquaman, which restrict this idea a fair bit. Yellow submarine.

[@nathansamuelson]

I thought about, considered the idea, then you showed the clip of the massive full transport ship... There's no beating that.

Yellow Submarine. Also makes sense, honestly. Thanks for explaining this, F&E.

[@Mate397]

Huh, that's a concept I never thought of before.

[@yetinother]

Yellow Submarines can hold at least 10% more due to the lighter colour which improves the buoyancy and surface tension drag coefficients

[@GarlicAvenger]

Pretty sure the conversation would be like this; "Hey guys, lets make a CARGO Submarine! Wouldn't that be cool!" "Yea, it would be, but you're taking the water resistance/drag of the water that a ship deals with and putting it over the ENTIRE vessel. And also requiring a sealed, pressurised vessel that can't even be anywhere near the size of a surface vessel... So because this is literally worse in every way, then NO. A cool dream, but just NO."

[@Spedatr0n]

Definitely an interesting concept!

[@Ndw1995]

10:14 Not to worry, ice melting in a body of water does not raise the level. Try it for yourself with a cup

[@VestedUTuber]

The cost to time savings just doesn't work out, and when you're shipping by sea volume and cost are much higher priorities than transit time. The only real legitimate use for a cargo sub is the delivery of supplies to units operating behind enemy lines in a military conflict.

To improve Japanese Armour capacity in WWII to counter American Shermans, the Japanese brought a Tiger Tank from Germany, which was disassembled into parts and transport via Sub.

[@nobilesnovushomo58]

You missed the part where the allies blockaded American ships in WW1 from entering German ports after they simply committed to the trade, the english and french were forced to buy and continue to buy everything from the Americans the germans would've bought or risk opening upon american ships themselves, and then after the war, simply dumped the cost on Germany.

I think there is an error at 2:03 the name of the island is actually Corregidor Island.

[@rainy131313]

Yellow submarine. My guess was cost as well. I could see a shallow-depth submarine cargo ship used as a fleet/national backup transport for stealth and for high value commodities and things that have to get through regardless of weather conditions... but that generally precludes civilian use. Ideally, I could see a portion of our RORO military ships supplemented by a transport sub. It would not be stealthy without being stupidly expensive, but it could go anywhere, anywhen, and that'd be a big selling point for the military for whom cost is second to function.
