Ya Ya is a

This reads like an apology for having such a long video, but having finished it now, I wish it had been longer! This was a cool snapshot into the operations of Navy submarines.

L

This was awesome.

I don't see an underwater tank full of soldiers. I see an unruly tube of gases and fluids carefully controlled through another world where nothing is as you know it by engineers and scientists. It must be another world, it is like they are traveling through deep space. Destined let me ask you this. Which are you more afraid of now, Space or the crushing depths? Tangent A submarine is complicated enough to equal the level of complexity in a powered airship with better speed and manoeuvrability then any in existence right now IF it could also go to space. But wow it crushes the sub by design and there's a string as a genius easy way yet terrying, to tell how much deflection the sub is sustaining. A physical analog of the external pressure on the sub. I imagine if it snaps that's also the physical indication the max depth has been exceeded as that's what I would do knowing the string gets tighter. I think that's information that means nothing if you don't know the depth but who's that guy that used paper to that's bomb yields. Scary to imagine how deep destined is since he is a smart man and very worried and cool part is she still has at a guess upper limit 30% left if it travelled 4 inches to be that tight.

This is mind blowing, there’s so much more to a submarine than I could have ever imagined.

Yes, it's absolutely mind blowing, but not only what's IN the video, but even more how it's made. Incredible efforts! Thx, SED, for the whole series!

Da REAL nooklear wessel!

@Super Geek would have been nice to hear Rhett playing a telecaster with a Marshall 50 watt Amp under the ice . But I get it we can't have our enemies hearing the good stuff. Thanks 😊

@G Mac Sorry. Subs *RARELY* use active sonar --- therefore, there's no beat. I'm pretty sure that if you held an acoustic guitar against the metal of the hull on the inside of the boat, though, that the sound would project out into the water. It would also be likely to result in a visit from the Ops Officer. Sound projection is very much frowned upon.

Still waiting to hear Rhett play guitar through the hull of a submarine to the beat of the sonar.

The access the Navy allowed Destin on this sub was incredible, truly an honor for him and us, his audience.

@Wilbur Worm then you'll no doubt like the Sub Brief channel too: it's what got me interested in submarines.

Absolutely fascinating

@David P Say whatever you want, but it's effective for sure. I want to sail on nuclear submarine after watching this and i'm not even american!

​@DraculaIf it involved the CIA it would not fit the title of the channel

now do one in The CIA head office

At first I was like "why is this video so damned long?" then, after what seemed like only a few minutes, I was like "wait, no why is it over already!" - way to make this so interesting and immersive! Thanks, Destin!

AGREE, IT FLEW!!!!!!! WISH IT WAS TWICE AS LONG! THANKS!

I'm sad the series is over. This is arguably some of the best content on your channel. I hope to see similar style stuff in the future.

I don’t spend over 20 minutes on YouTube video usually, but this was absolutely worth it. Amazing content!

@Hugh Huang ive learned more about culture and whatever else I like to learn

@Wayzor yea bro and it make things worse, unless u talking kush

@Wayzor jesus

They make ADHD medicine now.

@Tad Craze ...Just a joke, man, lol.

Can’t wait for the Smarter Every Day International Space Station Series

Seriously I’m slowly wondering about the join the navy see the world, is space force gonna have a similar saying? See the world from the moon maybe 🤔

"Thanks, Elon!"

@Veezerr Scharnfrost he might actually miss the ISS and go up to the next gen American space station

@Saurabh Kumar Singh they literally did this EXACT thing last month

@Get some knowledge it easily could.. SpaceX launched tourists up to the ISS last month A nuclear sub is harder to get onto now adays security wise

Thank you US Navy for allowing us to step into the submarine world, it was awesome.

Agreed 1000%

I'm slowly working my way through all of the content on this channel and every single video feels like those rare instances in high school, when something actually sparked your interest and you wanted to understand it and know more about it. Thank you for putting all of this amazing knowledge out there for free!

. . . When he speaks about hovering, I can't imagine how extremely difficult it would be on an Attack Boat without a dedicated Hovering System. Both Boats I was on were Ballistic Missile Boats that had a Hovering System which was dedicated to keeping the Boat at a precise depth at 0° bubble! Kudos to these highly skilled Attack Boat Submariners!

@Patrick Winn I was on the STONEWALL JACKSON and the TECUMSEH and both of them had a Hovering & Depth-Control System for Missile launches.

Chief of the watch pump out 2000 from the forward tank. I don't remember a hovering system on my boomer, and I stood many a watch in the control room. If we had one it was the stern and fairwater planesman. USS Henry L Stimson 75-79 Gold

@GOD's BEAUTIFUL FLAT EARTH globe

Flat Earth.

I was on a Sturgeon class and we had a hovering system. However our main valve leaked so much that it could not maintain depth properly. Bummer since it knocked us out of a dive operation with Seals using the escape hatch.

Destin, "once in a lifetime" doesn't even begin to the describe the opportunity presented to you with this experience. You deserved every minute of it, and we are grateful for you sharing all the details in your classic smarter-every-day way! Thank you!

This is a very honest and smart way for the Navy to recruit and definitely beats a flashy advertising campaign. You can't say you don't know what you are getting yourself into after this! Such a great series.

This series really is the definition of a win-win-collaboration :)

@Grimm Reaper NJP. He was trying to do something called "hot swapping." In normal operation, you pressurize one sans tank, blow it empty, vent the pressure, then repeat on a different tank. He blew the first tank like normal, but tried to roll the pressure over to the next one to skip the venting/rebuilding pressure process. It is significantly faster, but absolutely not an authorized procedure, because if a single venting line is left open, such as in our case, the entire fresh tank of sans will be blown through it with no way to stop it once it has started.

@Maverickib what happened to the lad that messed up the valve lineup? Also did he leave just one wrong valve open or shut the wrong one?

@Maverickib In 1999 when I joined they gave me the choice of submarine sonar or (submarine) fire control. I went with sonar. Wanted to be close to the action and have as much need to know as possible :) love getting to say "I can't tell you" when I know, but can't tell. :) I got out 2003. :)

@Maverickib LOL Never happened to me but I lost count of the number of officers wearing their rig for red goggles that have experienced this humbling event.

The sub series was one of the most informative and interesting things I’ve ever seen. Thank you Destin and U.S. Navy!

Watched every minute of this entire series and it was outstanding! Thanks Destin, USNavy and to everyone who made this content possible. Great stuff!

Great Adventure!! I was in the Navy 10 years, and this brings back such great memories of how amazing the Navy can be. I was a Hospital Corpsmen, and had a very diverse experience, from assisting surgeons in hundreds of surgical procedures (in hospitals and combat tents), working as a Navy Instructor, developing an EMT program, as well as working as a Deputy Public Affairs Officer--my highest paygrade was E-5, but the Navy provided me with a Masters Degree. I recommend any young person to pursue a career in the Navy. I was interested in working on a sub when I was considering my career path. That path did not match my personality enough, however. Think about how these sailors exist in such tight spaces. Not only are they selected for their extremely high intellectual capabilities, they also posses untouchable emotional stability. So basically, they are a very tight family of very well adjusted people, doing one of the greatest jobs on the planet.

Absolutely amazing! Fascinating learning about this sub. Everyone you talked to were extremely smart in their knowledge of their specialty, and they all worked as a team because they all depended on each other. The Navy is in good hands with these dedicated sailors. We are all Smarter after watching these videos. Thank you for these series!

Wait, this was 42 minutes long? This felt like 20 or even less. Truly one of the most interesting series I've watched and enjoyed in a long time.

Felt like 20 for me too. Probably because it was at 2x speed

Saw this comment when just a couple minutes in and thought dont be silly, next thing I know he's wrapping up and 40 minutes have passed without me even realising

That is the answer.

Do not watch on 2x speed, dude! =)

This video had me hooked. I didn't even realize it had been that long.

4:45 a civilian literally just told them when to dive. Even though they were humoring him... the fact of giving one command to the entire boat had to feel great if only for a few seconds.

This was an awesome series!! My dad was on a Submarine in the US navy during Vietnam. He told me stories, but seeing this was amazing. Thank you!

What an amazing series! Never had a clue what it was like on a submarine or why anyone would want to be trapped under water for months, but now I can see how interesting it can be.

The submarine information is awesome, but I think the best part of this documentary was the great folks of the US Navy. How blessed I feel knowing those guys are there every day protecting our great nation. Great video.

Seeing the photos of the kids behind the captain made me realise that you’re letting the families of this crew see what their parents and loved ones do. Someone gets to go “That’s my Dad!” And that’s a super special gift.

I had the privilege of living on a sub base as a kid, and yeah, this video would have been very special to my friends if YouTube was a thing then. Not seeing your parents for months at a time is tough, but you're also very proud knowing that somewhere out there they are doing important work with other outstanding individuals, for the best navy in the world. Kudos to the Navy for doing what they can for the families.

Motivation.

Yes, my dad is a former (nuclear) submariner and this was absolutely wonderful! So much to talk about with him and he's had a blast reminiscing as well.

18:41 for those who want timestamp btw

@Alexander Gavey proud yes... coolest kid in elementary not likely lol

FASCINATING! I can't remember another series that pulled me in with amazing KNOWLEDGE that I never knew I was missing out on. Thank You, ALL. And, Go Navy! 🥳

This was just absolutely amazing, thank you for doing it, and thanks to the men and women on and related to the boat that let this happen. Much appreciated :)

Excellent video series, thank you! I had no idea that these submarines are so sophisticated, and it made me all kinds of happy to learn about all of the engineering that went into them.

AWESOME, IMPRESSIVE maneuvers! Amazing documentary. Thank you Destin! And thanks to the U.S. Navy individuals who facilitated this and, to the submarine team that allow us to see your amazing, work. You make us proud!

42 minutes... man I had stuff to do today Edit: Cartesian divers are one of my favorite physics toys. I've been trying to figure out different games to play in the bottle for a few years. I've haven't gotten far. Double edit: Good thing you kept the popcorn ceiling. Made for a great illustration. Triple edit: Great series. Congrats on 10M!

I think the toy you are looking for is called "Dyna-Diver". Had this toy in the 70's when I was a kid, I loved it so much when it broke I bought another one. There are many images/info on the web. :-)

@arfyness yes, in the 80's, maybe early 90's. It immediately reminded me of that.

Y'all have so much subs........

Get your cartesian diver through some kind of maze in the bottle?

A hook on the bottom of the diver, pieces on the base of the bottle with a loop or ring and try to hook or catch the pieces

Great video Dustin! Many of us have been curious about submarines, and particularly the nuclear variety and your video answered many questions. As much as I believe we should be diverting some of the money we spend arming ourselves to the teeth, I can only be humbled to see the great people who are doing the work.

I just want to say “thank you so much” for making these videos. I appreciate you and all the wonderful people you came in contact with in making them. You’re doing a great thing.

Destin, thank you for this great series about our nuclear submarines and especially while under the ice. As a submariner on boomer subs in the 1970's I always wanted to go under the ice, never did but your series and the members of the boat you visited made it near possible via youtube. Thanks again and to my fellow submariners God Bless!

Wow! This is truly incredible content. Thank you Destin for producing this amazing series. Kudos!!

Just watched the diving and surfacing videos. Awesome job. Thanks for sharing these incredible videos. Informative and entertaining.

This is one of the coolest video I have ever seen! Thank you for making this content! You are so lucky to be able to do this. Thanks for taking us along!

This has got to be the most fascinating 42 minutes I’ve experienced in a long time. Felt like 5 minutes.

Just revisited the series and it still blows my mind how hard and complicated things are in the world underwater.

I can't be the only one who is EXTREMELY happy that of all people Destin was able to experience this! You were the right person for the job Destin!

100%. We're so lucky to have him. Thank you, Destin!

@SmarterEveryDay thank _you_ for the amazing videos

@SmarterEveryDay you do outstanding work

@Cogumelos Azuis I second, third and fourth that! 😂 It would be an insight into space like no one else could provide!

@SmarterEveryDay just keep doing what you do Destin many people around the world are able to learn more than they ever could in any kind of school setting and I for one appreciate that! So thank you again!

Thank you Destin, and CMDR Cornell! What an interesting set of videos you've made. I really enjoyed it and have passed it on to friends.

This entire series was ABSOLUTELY FANTASTIC. I can't say enough how much I learned and appreciate the hard work to make this; and thanks to the Navy for actually letting this happen... amazing.

Another incredible video, Dustin! I know this may sound sappy, but my favorite part is when your video begins, but my least favorite part is when it ends. SO MUCH INFORMATION! Love it!

Dustin, you never cease to amaze me with your good grace, humility and off the chart quality of content and production. Thanks for making me smile!

Destin, I spent almost 4 years on an attack sub, taking her all the way to decommissioning. I was one of the guys operating the reactor in the back that I’m sure you didn’t get to see during your visit. I’ve really enjoyed your series and am quite surprised the Navy allowed you to do it - you must have really impressed someone higher up!

@Timmy2Fingerz chances are you gonna share your coffin with them. so better be a teamplayer inside a sub.

From his previous job working on missle development, he no doubt has the clearance level that made the navy much more comfortable with him doing this.

How many Roentgen did u get ?

Bob, thank you for your service and great to here your perspective….and I thought the same thing about his access. From his time with the Thunderbirds, I think all Branches see him as an awesome promotional outlet (more organic maybe). Anyway, thank you Sir!!

Chinese "UAPs" are deployed from submarine and operate in water and air and can go 10000mph ++. UPAs in the news are Chinese Hypersonic First Strike Weapon With EM Field Propulsion. See my main feed comment. And thank u for you service.

This was an awesome series! It made me appreciate our armed forces so much more. And I very much appreciate you taking the time and their allowing this access to show us the amazing level of talent we "civilians" have giving us our freedom.

Wow. What amazing series of videos. Thank you so much for getting these experiences on video. I love submarines, but really haven't seen much that shows how they operate from a first person perspective. Thank you so much, and thank you for your bright, joyful, and inquisitive personality always bringing amazing chances to learn!

This series was amazing. I have been reading the “Jerry Mitchell” series by Larry Bond and this series of videos gave me a much better understanding of submarines and the silent service. Thank you for doing this deep dive.

this is an awesome series. watched it as it came out. bindged the whole thing again... just amazing! I remember when smartereveryday videos were made in a backyard. So happy to see Destin go so far and keep the same wide-eyed curiosity!

I just realize that I watched this quality series for free. Such a wonderful journey Destin!

I recommend his patreon, it's a great way to support him :)

@DaBeast34 adblockers are old tech. It's all about youtube vanced now, except for the apple users.

It's not free. Your data and ads. Might feel like free but is it?

This was the first of this series that I watched. And I can't believe that making good YouTube videos got a regular guy inside a nuclear submarine way up in the Arctic, not alongside a dock. Amazing what you've built with your channel.

this is so cool. I love that you have the passion to go out on such an expedition to try to show as many people as possible stuff no one would ever know or experience.

This vid was awesome! Thanks a lot for making my covid-19 quarantine so much less boring! Keep up the good work! All best from Bulgaria!

This video series was amazing. Thank you, and the men and women of the Navy who made it happen. I was also excited to see you recommending Thunder Below. I didn't buy it on Audible, but I've owned the book for many years and have read it 2 or 3 times. It's an amazing read.

Every time I think "why did it take so long to get the next in this series" I am reminded of exactly where and what you had that camera pointed at, and how amazing it is that this series exists at all. So thankful!

@AVRO Architect no doubt we only saw a fraction of what is in that room. And Destin most likely has a good security clearance level from his previous work on missle development, which made the Navy comfortable with trusting him with what he would see in person.

I'm frankly shocked they even let him in there to be honest, the bridge is literally the whole brain of the operation. The fact he even saw what is in there would have been considered a severe OPSEC breach when the sub was built

A.M.A.Z.I.N.G. series Destin!! I just binge-watched it after having several of the videos in my “watch later” list for months.Thank you so much for putting it together and for your particular style of reporting: always smart to ask interesting questions (and follow through with great explanations during editing), and always super-respectful of *everybody*. Thanks so much to the US Navy for facilitating it as well! I loved how everybody was proud of their work and eager to show it (with the appropriate security restraint). I particularly loved how the captain agreed to let you put a GoPro on them for the surfacing: “that would be a cool shot” summarized the entire attitude to let us viewers get as complete of an experience as possible. Please keep up the fantastic work you produce.

This is one of the best things I've ever watched. Great series, super informative, well put-together, and presented. Watching from Limestone Co. Alabama!

I love these guys. What an amazing group of humans. The navy is awesome!!!

wow! thank you for such an amazing journey trough this adventure. I'm a french canadian and just devoured this series. Thank you again. keep up the good work.

actually sad this series is over, it was some of the most interesting stuff I've seen in a while, so much cool stuff happening even with the censorship.

@Artemis Logic well theres also knowing how they come up with information they need to make decisions could allow others to come up with ways of countering their specific way of information gathering.

im guessing the censorship is just them not revealing the coordinates of where they surfaced, maybe they use that spot a lot and dont want a potential enemy to know in case of war, and them not saying how they know where to surface might also be that same reason, and/or they get the information from an external source and would be vulnerable if an enemy were to stop them getting that info

@KARASIRA I'm sorry that pun was SUB par =p

Do you mean the censor ship ?

Wow. What a collaboration. That was such a great episode. Kudos to you, and to everyone who made it possible.

Thankyou so much Destin for giving an insight on how subs operate under the polar ice caps & how they surface. Very complex, very difficult & with hair trigger reaction controls with the prop & the planes.

Thanks to all the submariners for their dedication and training, amazing the tech and knowledge needed to perform their duties.

@Emergency Rapid Response Team It sounds like you have a hole in your tinfoil hat, you might want to look into that. Good luck!

I just finished this series and was entertained the entire way through! Great job on it!

Hi Destin! I'm the guy who narrated "Thunder Below!", and I'm so glad you enjoyed it. I'm grateful for your kind words about it, and I hope anyone who decides to listen to it based on your suggestion enjoys it also! :) I've been following this video series since the first one, and it's been a nonstop joy to watch. Thank you for doing this series, it's been fascinating.

I read the book a long time ago when I was in high school ( I’ve always loved submarines) and it was really great to experience it all over again! Thank you Destin, for recommending the book and doing this sub series and thank you Corey, for a wonderful telling of a fabulous story.

​@Rubixx14 I didn't have to practice it much, but you almost NEVER hear those kinds of "effects" done by the narrator in a book. I only did it for this one because Fluckey's narrative style was very personal, and it felt like it added to the story instead of distracting. I wanted people to feel like he was telling you the story himself.

How many times did it take to perfect your klaxon sound? After a few hours I was doing it along with you while listening in the car haha!

@SmarterEveryDay 9

I enjoyed the audio book immensely! Thank you for your delivery of a great story!

This is a great video. As a young mechanical engineer I designed parts of submarines and found this really fascinating. Like Destin, I understood the physics of trimming the sub, but you don't think about it all coming together until you see it. It was also great to see the professionalism and discipline of these sub-mariners. By the way, to us Limeys she's a boat, not a ship.

This was a great series of videos. I'm glad you were able to share these enlightening topics with us. My only wish was that I was there, but you showing it to us like this... this is amazing.

This was... AWESOME !!! Guess, I'm gonna work my way backwards through this series since I started with this one. Great crew that captain has. I couldn't imagine the stress that every single one of those submariners have in just doing their daily job, and yet they do it with such professionalism and distinction. America has so much to be proud of !!!! I was thinking the whole time when they were clearing the ice how great it would have been to be able to serve up a Margarita to every single hard working individual on that ship, just a small way to say .. Thank you !! Great, great video. Thank you !

Thank you so much a huge thank you to everyone involved in allowing this video to be shared on YouTube, I knew nothing about submarines so this was a huge learning curve as I had no idea what happened when a sub was underway or carrying out different manoeuvres.

To the person that did not want to be publicly recognized for getting these videos through operational clearance: A big US flag salute to you! Thank you for making this all happen!!!

@Alex Schleuning that’s fantastic. Thanks for the update. Reminds me of my interactions with people at China Lake Naval Air Weapons Base: There’s Marines embedded with most of those naval operations. Makes sense that the Marines would give him/her a commendation too.

Don't worry, he got a Navy and Marine Corps Commendation medal for his efforts!

Thanks for the instructional video! I've always had trouble surfacing my nuke boat in the Arctic, now it's a breeze,thanks!

Wow this is so rad. I’ve always thought submarines were interesting, and scary!!! Just like Jody said at the end there! Now I don’t feel as much scared but a lot more interested. Seriously great video, thank you! I loved this!!!

Absolutely brilliant. SmarterEveryDay is one of those peepholes into the fascinating and complicated world of science and technology we rarely think about . . . but should know. THANK YOU for bringing this material to life.

Great series! I would also recommend reading "Gallant Lady - the Biography of the USS Archerfish." Not only did she sink the biggest vessel ever, but she also was one of the first subs to explore the polar ice. Also Admiral Fluckey was in charge of her during some of her explorations in the 60s.

The dislikes are from the military personnel who had to go through frame by frame blurring out all important details for a 24 hour long multicam supervlog.😬😬

🤣 this might be more true than you know!

Some are from Chinese and North Korean naval staff too! Hahaha

Having been on M60/M1Abrams tanks with Security clearances and the excitement that the military has to offer.. I found this series absolutely fantastic!! Loved every minute of every video.. Thank you to all our Service men and women who put it all on the line each and every day..

Thanks for the great videos on the submarinars. My dad served in the sixties on the George C Marshall SSBN 654. and he told us some stories. if he was here today I'm sure he would marvel at the progress in technology. he spent most of his service under the arctic.

Such a ride!!! I knew so little (still) but learnt how dynamic this is. Also, I saw how professional that the crew are 👍 I salute all our military and am happy to feel safe in their hands 🇺🇸

WOW! Amazing. Much respect for our US Navy and the folks who work on submarines. I'm claustrophobic and wouldn't last 5 seconds down there. Thank you!

Wow. I am a former sub-sailor. The access you got just boggles my mind. I can tell you that folks I know of high ranks find your video work fascinating and incredibly accurate. You did an amazing job as a great service to the Silent Service.

This video was awesome to watch. What a great experience this must have been.

16:35 I would love to have a more in depth look at limitations of atmospheric pressures at that depth with the sub wanting to fall. The thought of reaching a point where you can no longer go up is scary. How deep would that have to be?

This is an incredible video!!! Thank you for producing it, Good Job!!

Scary huh? I had a neighbor who was a submariner. He told me several things over the years. He is a brilliant person, and I mean brilliant. Degrees in Nuclear Engineering, Math and Law. These guys and gals on board these subs are some of the smartest people we have in the Navy. Each and every one of them makes us safer by what they do every day. Thank you all.

As someone who served on a sub for 4 years, let me just say. This series barely scratches the surface on the tech and procedures that are needed to operate these machines. It's also fun knowing what some of the redacted audio is too lmao

@AcciK my suspicion is that it might be the reactor room saying something about status or other metrics, which is all highly classified.

@AcciK it's redacted for a reason. I don't want to go to prison lmao.

@Azer White depends on what you want to do on the sub, there's a lot of math involved in pretty much everything. But really you just have to enlist lol. And tell them you want to do subs, they'll jump for joy

@Azer White If you want to know what jobs you could do in the military go talk to your recruiter because they will have your interest because they want you to join. Just ask them about what jobs they would recommend and what it would take to attain those.

*Calls KGB* Yep this guy right here

This was amazing. Thank you for the video and the experience of watching such an extraordinary event.

Thanks for making these videos Destin. So awesome!

Thanks to everyone involved in the making of this video. Truly amazing.

This was truly a remarkable video with so many fascinating points! You went through a lot to make this and I appreciate it!

"Can you tell me the difference in depth?" "No." Probably seconds later: "I'm doing the math in my head." Power move, Destin.

@bionku the better the quality of the recording of a sound like that the easier it is to detect and ID a vehicle on sonar, and the easier it is to counter the vehicle in a conflict.

@Dániel Bulyovcsity that number just means that it can go at least that far, the exact limits of major military vehicles like this are never intentionally published, so it can probably exceed that number.

@Dániel Bulyovcsity If you can do the math on how much the hull goes in,for a given depth, I think you'd be able to calculate the absolute maximum depth before it starts to flood.

If it’s serious, then 800~1200 meters to my imagination is a serious depth.

That sub was diving at roughly 0.7 m/s. The sub's test depth is ~300m, so it would take 7 minutes to reach that. I'd guess that the depth Destin went to was ~200m.

Destin, I've watched this entire series a few times now. And It's absolutely amazing to watch and to learn and see you process the information in the moment. The people and the situations you got to experience is top notch. And while I'm at it - Merry Christmas to you and your family

@Benoit Vanhees I'm pretty sure that it *is* actually Destin...

Just call the man by his real first name, it's not classified... Dustin

Absolutely fascinating. Thank you for this look into something I would have never seen otherwise.

This is crazy that you were able to do this. Thanks for the great content!😁

What an amazing experience! Thanks for sharing this awesome experience !!

"Deep dive series," I get it, Destin. This has been my favorite series since the helicopter series. Some of the best things about your videos is that they really expose the levels of complexity behind things you don't really think about. The idea of hovering a submarine and the sophistication behind that process is incredible.

Same. The helicopter one is amazing. I am a prototype machinist in the aerospace industry and just thinking about what all goes into keeping control of a helicopter blows my mind. Same thing with submarines. Amazing feats of engineering.

That's amazing. The pinnacle of technology - a string from side of the hull to the other. I just love when simple things help with really complicated ones. Like flying a plane by a glass of water

What a pleasant team of servicemen! Thanks for posting, very educative.

Amazing to get to see this even if a limited look into the vast mystery of the art of submersibles. . . Thank you for the work your team does. Most of all "Thank you for the service" of those you met on the journey.

What an incredible series! Absolutely loved this!

Hands down one of the best documentary series I've seen. To meet the crew in this natural and uncut way is such a blessing. So much of TV is over engineered and fake. This is just straight up filming and talking.

This is very much a "cut version".

Couldn't agree more. And I'm in the category of the farthest thing from any possible type of engineer there is out there.

Agree

Thank you! Absolutely awesome video! Next Deep Dive into Commercial/Military Aviation?!? I wanna know more about turbine engines, compressor stalls, fluid/aerodynamics and weather!! 🤓Keep up the awesome work.

Fantastic series! Thank you so much for taking us on board.

You are so lucky!!! I’d love to I mean absolutely love to go on a submarine. It’s been a life long dream. I wanted to be a submariner but my life went wrong. All those guys deserve so much respect. Their jobs are all so important. And they do it so well and with absolute clarity. Loved this video!!! Thank you

all i can say is WOW!, I spent 21 years in the Navy, grew up in the Navy from when I was 19, and I found this video to be incredibly interesting. My first ship was a Sub Tender in San Diego, so I was lucky enough to board all the submarines in San Diego back in the day. What a talented and elite team they are!
