Noticed how All of em has overkill technology to protect the people inside and bring them back to the surface while the titan sub is just an oversized trash bin glued with other metal
@@renziie2804 kind of makes me think of the SR-71 Blackbird, built in the 60s, not revealed till the 90s... Imagine what theyve got up there in the skies thats newer and still classified. Meanwhile Russia, China, North Korea etc all do these big "show of force" military parades trying to spruke how advanced they are and could take on the world lmao These DSV are just incredible technology! Not even a simple diving bell could do this. The pressure of the air inside from the water rising in the moon pool would be enough to kill a human
well triest was also only rated for one dive, the others can come and go multiple times, but yeah, triest helped pave the way to what was once though impossible.
The ingenuity and perserverance of humans is incredible really, just sheer inquisitiveness on an epic scale. Probably on par with space exploration if not more challenging 😮
#1 DSV Limiting who held the record at the time of 10,925 meters is made by Triton Submarines in Sebastian, FL, USA. They make commercial subs-deep submersibles with a variety of models. I never knew about them and they are just up the road from me. It is sad that the Titan people did not raise enough capital and buy a real submersible versus a homebrew thing with carbon fiber. #2 The Trieste was a long time ago and an amazing accomplishment.
Ver este video y concluir que el #Titan era una simple lata de refresco, paz a las almas perdidas en esa tragedia. nadie le gana a La fuerza de la naturaleza
It's not that they don't have enough money. They wanted to build a deep-sea submarine in a completely different way, and their inspiration was NASA and the aerospace company Boenig. The director of OceanGate wanted only young people in the construction team, he was not interested in older experts, he said so himself. He was originally a pilot and had to leave due to eye problems. He constantly pushed aviation concepts into the submarine project.
@@michalpetrilak3976 pushing aviation concept into submarine is absurd, aircraft hull was design to hold inside preasure, while sub was design to hold outside preasure☠
No, it wasn't a money thing. He wanted more space so he could stuff more paying customers into it. It would take far too large a sphere to manufacture to get 5 people into.
Exactly, I was just going to mention this as well, it's not a minor detail because the whole reason USSR commissioned Rauma-Repola in the late 1980's was because they were incapable of producing one themselves for the lack of technological know-how and facilities, and pretty much all countries in the world with enough of both refused as they didn't want to anger the US.
@@IgorSyConfidentionalThis is bullshit and you know it. The special steel used was of US origin, and design of the vessel was made by Rauma-Repola and its partners. All stupid vatniks can do is lie.
2:16 The Alvin (a sister ship) has been updated to dive even deeper. They just did an $8,000,000 dollar retrofit. It's new max rating is 6,500m. It's made 5,000 dives.
Any regulated sub is capable of MUCH deeper depths than advertised. That's what certifications are for, as a guarantee of the minimum, not of the maximum.
@@bionicgeekgrrl Imagine if NASA sent a DSV to the under-ice oceans of Europa or Enceladus. Europa's ocean is thought to be 60 miles deep. But it's also a small moon with less gravity, so pressure would increase more gradually with depth.
The DMSs Mir1 and Mir2 were built in Finland by the company Rauma-Repola as part of a joint Soviet-Finnish project and under the guidance of the scientists from the Institute of Oceanology of the Russian Academy of Sciences. I.E. Mikhal’tsev was the project manager for the creation of the vehicles, and A.M. Sagalevitch was his deputy.
Thats right. The US security people as CIA and other thougt that Finns coud not manage to work It out and when it happend, forbid Finns to make any more of these deep dive subs.
@@jooger69 You're talking absolute rubbish. It's like saying that iPhone is a chinese phone because it was assembled there. Mir class was designed in the USSR. Finland was used because soviets didn't have an access to some parts because of sanctions.
@@GURken That is not historically accurate. USSR basically specified what they wanted, but Rauma Repola designed and built them. Finland didn't have access to embargoed materials and technologies due to CoCom sanctions as the submersibles were going to USSR.
@@annakeye tested at krylov institute to a depth of 14km . Obviously cannot ever dive beyond the depth of challenge deep since there is no deeper point
@@mingming9604 the Limiting Factor is such an awesome craft. It and Deepsea Challenger are examples of how you do DSVs right. Looking at those and Titan is like night and day, it's incredible...
Tiny correction, Mir vessels, two of them, were made in Finland. It was special order from USSR navy. Finns ask USA if they have anything against it, `cause Finland has no right to build submarines after WW2 Paris peace deal. USA laughted and answered, sure, we cant build submarine to operate 6000 meter below surface, you cant do it but sure, try. After Finland has build two of those USA denied Finns to ever build subs again, they were too good...
That whole Titan tragedy should never have happened. As a submariner back in the 1970's for 6 yrs, I will never understand why those folks got into a submersible that they couldn't get out of without outside help....and a composite hull that had never been tested properly?? I will never understand it.
it doesn't really matter what they are designed for, it only matters what has actually been tested. The #1 on the list is technically a no depth limit submarine, as it can literally go anywhere, but because the sea floor is only so deep, it has "only" been tested to the point shown in the video
It's smart to have a vertical layout. Decreases its drag when going up/down. If it can get to the bottom and return to the surface quickly, that conserves battery power and life support for use at depth. Like a vertical torpedo, I think James Cameron said
The TRIESTE is 100% Italian designed and built. It was later upgraded to Trieste-2 and once decomissioned it was SOLD to the US Navy for research purposes, the US has nothing to do with it's design or development. Also the Trieste reached it's record -10.911 meters in the early 1980's when the others barely were able to reach -5000m
@@Grouuumpf yes, Auguste Piccard and his father Jaques made the concept design. Then all the technicalities to actually build it were developed by: The main sphere: Società delle Fucine of Steelworks Terni The main porthole conic glass: Officine Galileo of Florence Main body: Cantieri Riuniti dell'Adriatico in Trieste Final assembly and special soldering: Castellammare di Stabia naval shipyard Each of these companies obviously had engineers and technicians that developed the details of the project
We all know why we're here, but my main interest is in trying to get some idea what these things cost to build compared to the Titan. Does anyone have that information, or can hazard an educated/ informed guess? To be honest, I wasn't aware until recent events that anyone was offering ordinary members of the public the opportunity to visit the Titanic, but the type of craft seen in this video are more like what I would have imagined people would be going sight-seeing in i.e. properly engineered, well-built, sturdy looking craft, with lots of sonar/ navigation/ tracking/ communications technology, and presumably redundancy for things like power and propulsion.
How to nitrogen and nitrox pressurize, without depressurising, even when rapid accent.? Depressurise slowly during surface cruising mode... Save money on nitrogen.?
I find it somewhat bizarre to put whoever arrived first in second place. As if to say that Edmund Hillary would be placed after other Everest climbers who are taller than him. It means that the next one who goes to the Mariana Trench will bring a digger. I suggest drinking less.
We should have full technological mastery of the deep sea by now. There's a huge space station in orbit but we only have a small number of subs with full ocean depth capability, and a single underwater lab in shallow water. We could do better. Many biological substances valuable for medicine are in the sea, like horseshoe crab's blood, worth 18 grand per quart because we can't synthesize it, and it detects impurities in pharmaceuticals
Note: No Titan mentioned here, and anyway the 4000m looks like nothing compared to fhe 11000m...so no reason to use an experimental plastic rc boat if a real thing is available...
China has a new submersible called Fendouzhe that dove in the Mariana trench in 2020. They are now in second place, short of the Limiting Factor's record by some meters
There is also a Chinese bathyscaphe that has reached the bottom of the Challenger abyss, it is the Striver (Fen-Dou-Zhe), which on November 10, 2020 reached a depth of 10,909 m (35,791 ft).
@@brocklanders6969 but technologies are totally different. Chinese one is many times more advance. You must understand between old and new technologies.
@aungaisum8654 we do understand....which makes the first two gentleman's trip far more impressive with old tech than a group doing it with 60 years of advancement.

日本の「しんかい」は、１００００ｍ以上潜れるけど潜らないだけ。それより、これまで２５００回以上探査していることの方が重要だ。 Japan's "Shinkai" can dive over 10,000m, but it just doesn't dive. More importantly, it has been explored more than 2,500 times.
Could you please include American as well as metric measurements.! not everybody knows the metric system. it's so irritating most Americans will turn off videos because we have NO idea what metric measurements mean
If I made a video and told you this sub went 72000 fathoms down and this other sub went five thousand fathoms down you would have no idea what I was talking about and that's how Americans feel when you only use metric measurements
