While Dianna is recovering, I'm leaving her videos running 24/7 in the background so her channel gets more views. The algorithm is hungry for this attention, so I feed it to support her.

[@randint]

I appreciate your effort to get her videos more views, but KZbin probably has taken some measures to stop counting repeated views of a video from the same device. Therefore, if you watch a video over and over again, say 20 times, it would probably only count as five or six views. Even if you watch all her videos on the channel one by one, it'd probably not be much better since KZbin can detect that you are trying to farm views. A much better option would be to like all her videos.

Some of you caught the drone at 18:25 was stuck suspiciously close to us. That's true, usually DJI drones can fly miles away from the operator. Here's what happened: The drone was originally paired with Levi's phone. But in the extreme cold, Levi's (older) phone battery died within minutes - an Arctic weather issue we hadn't considered. So we weren't able to use the drone at all. Fortunately, I had downloaded the DJI app on my phone. Unfortunately, we didn't think to log in before leaving Alaska. (There's no wifi on arctic sea ice, it turns out). Flying without logging in meant the drone was limited to 50m horizontal, and 30m vertical. Wah wah. Also, we’re still working on the videos about how the submarine navigates and communicates with the outside world as well as what it was like living on board if y’all have any questions!

He was the best dad ever, and a legit brilliant engineer. And because of his work, and the work of engineers that have come along since, all you guys made it back safe from your dive. He would have enjoyed this video. He passed away several years ago now, but this video reminded me of him. Thank you for that.

what does "life support systems" mean in this context exactly? just curious

@@sittingturtleduck I assume something to do with oxygen generation

[@extrastuff9463]

@ Probably a bit more too, removing CO2 is pretty important even when there's enough oxygen left to breathe. I could see locally stale air being an issue too in a submarine with various rooms and narrow corridors/closed doors between them without any kind of draft from outside air. So probably a mixture of forced ventilation and various measuring points along the boat. And I'm sure there are other byproduct gases of humans living in an enclosed area for too long one might want to take care of on top of that. I'm tempted to look up that series Destin (smartereveryday channel) did again to see if it has any specifics for whatever submarine class he was in.

@@extrastuff9463 yeah Destin has one whole video on it from the submarine series

[@flibbertygibbette]

​@@sittingturtleduck I have no idea, at the time that's all he would say. When I would ask him for specifics about his work, he would just laugh and say, "that information is only shared on a need-to-know basis, and unfortunately, according to the US Navy, you don't need to know." Heh. He was a big ol' soft-spoken nerd, so imagine Mr. Rogers saying that and you'll get an idea of the tone he used with me as a kid. All I know is that he was first designing electrical stuff for life support systems for various deep sea craft (one of his early projects was working on a deep sea craft with Jacques Cousteau, who had some kind of brief partnership with the US Navy on developing the tech, from what I understand) and then after many years of working in ocean engineering and getting successive security clearances eventually was in charge of a team that designed/developed systems to keep people alive in nuclear subs when they were submerged. I always assumed it had to do with making sure people could breathe, so that's all I got! The other comments talking about supplying oxygen and removing CO2 are probably correct.

I served on both a 637 class and a 688 class submarine during the height of the cold war (70's and early 80's). Crossed the Artic Circle but never under the ice. I do remember when we were at periscope depth up north and ran through a temperature inversion and popping to the surface. We had to flood hard to get us back down, but once we got out of the inversion we sank pretty fast and the trim pump could not keep up with the depth change. The Officer of the Deck considered blowing the ballast tanks but changed his mind and ran up a couple of knots of speed instead. Submarine life is 99% boring interrupted by shear terror.

[@mysticwanderer4787]

Brings back some memories. I have done more than one Ice-X on a submarine. It is indeed serious business. We started doing these in the late 70s and early 80s as the Soviet Union started to use the Arctic more and more as their private lake. This is where they like to hide some of their ballistic missile submarines and wherever you find a Soviet or Russian missile sub you are going to find an American fast attack submarine to make sure it will not be able to launch its deadly payload. The Soviets designed the Typhoon class of ballistic missile submarine specifically to remain motionless under ice thin enough for them to blow their ballast tanks break through the ice and then launch their missiles. That is why it is so big with specific design features to enable them to break through the ice and clear their missile tubes for launch. It was never a "Cold War" for submariners and the war to protect the United States from unimaginable destruction is still ongoing. The silent service never wants publicity or thanks. Just knowing what they do is vital to our survival as a nation has always been enough.

I find the fact that you used a Russian submarine silhouette at 5:38 pretty funny. Great video over all. Welcome to the 1% of 1% who sleep under the waves. Also a bit of a correction. The ballast tanks do not run the entire length of the submarine. They are only on the bow and aft ends of the boat. The sonar sphere extends past the forward main ballast tanks to allow clear sound transmission though. The main ballast tanks typically do not go far past the start of the pressure hull (the people tank). At 11:36 you can see about where they are from where the decks straighten out along the outer hull.

This leads to a stigma when you tell people you are a veteran because all they picture is you with a rifle running into battle. Logistics, administration, and technical fields in the military have some of the best trained and capable workers in their respective fields. Not enough attention is given to them, the caliber of work they perform under incredibly challenging conditions (both physically and psychologically) and the transferable skills they possess when they are trying to transition out of the military and reintegrate into civilian life.

Such an amazing back log of videos to watch repeatedly. Miss you dianna. Still here to watch and support.

[@jamesmitchell4679]

Pretty cool to finally see the video that I had heard about. I was on the USS Illinois which was the other submarine that participated in ICEX 2022 alongside USS Pasadena. It was definitely a once in a lifetime experience. Can't wait to see the rest of the footage you guys got!

[@neutrino78x]

hooyah! I have to see how I can get involved in that as a civilian. I too was a submariner back in 99-03. Would love to be Qualified "rider"....all the adventure, none of the stress. 🙂

[@LeviTalksMovies]

Hey James! Levi here, we actually have footage of the USS Illinois passing us when we were out on the ice. We're thinking of using it in the next video. We saw it passing us right before we boarded Pasadena. Thanks for checking out the video! That's cool you were on at that time.

Absolutely awesome video Miss Cowern. I am Inuit. So a lot of my family live in those treacherous conditions every single day. That is just a part of life. I've never been to the Arctic yet but I would love to go. Mainly to see my people's way of life

[@hcos8139]

One more amazing vid in a row! You never fail to amaze me

[@brianfoss571]

Great work on this deep dive (of your deep dive), Di! Awesome that, even in the Arctic, GPS is accurate enough to detect ice sheet movement within an hour. Can't imagine how bizzare a 14-degree tilt was surrounded by water colder than the Titanic sank in, but seems you had a *ball as t*-ypical and rolled with it! Would be interesting to see that sub crew sit down with some astronauts to compare their experiences, since a submarine is kind of the opposite of a space station.

[@kentslocum]

Of course this is an oversimplification, but I would more terrified in a submarine than a spaceship, because humans can survive momentarily in a vacuum, but would be crushed and frozen instantly at the ocean depths.

[@garmmermibe5397]

This be bringin' me back to Destin's videos on Submariner life.

[@MinistryOfMagic_DoM]

Interesting to see another science tuber doing a deep dive into subs with the US Navy. Quite intrigued to see how each of your experiences are similar and different from each other's. Also curious to see if you come to similar conclusions about the experience.

[@ChaiLatte13]

I follow you on twitter. I'm so sorry for your recent LC/MECFS. I hope you can get back to doing this. how cool!

[@bobhopeful]

This is an awesome video. I hope you recover soon and can get back to enjoying life and hopefully sharing your experiences with the world.

[@davidwerner5944]

Feel your pain about (almost) losing your footage in the harsh environment. CNN, Nat Geo and I went in the drink (briefly) during SCICEX '99 (USS HAWKBILL). Each lost a little gear, but the number of surfacings equalled the number of submergings so it was a good day. Thanks for sharing your experience -- love your videos.

[@Meg_A_Byte]

Great video, always a treat to see these usually secret events happening. And congratulations on maybe the coolest sponsors I've seen on KZbin!

[@CraigAvis]

This was one of the most interesting videos I have seen in a long time! I have a love for the Arctic and always been fascinated with submarines. I have always wondered how they operate under the sea ice. I would drop everything in half a second to go on such a great adventure!. Keep doing more, I really enjoy all your content.

[@Civilian10827]

Get well soon Diana 🙏

[@jackprier7727]

Okay, this was wonderfully fascinating, esp. the part about quickly-changing seawater densities.

[@BudzBunny422]

I honestly miss school and learning new stuff all the time.

[@cixelsyd40]

My dad was a Nuke electrician on subs and during dependents cruises they taught us kids how to slide on pillow cases during angles and dangles.

[@mrt1r]

Just a minor correction for you. The main ballast tanks don't run the entire length of the ship, they are only in the forward and aft part of the ship. Also, variable ballast is not pushed around the ship using compressed air. A large pump moves water from tank to tank and tank to sea in the variable ballast system. Compressed air is used to rapidly push water out of the main ballast tanks during emergency situations to get the boat to the surface quickly. During a regular surfacing operation, air is blown into the main ballast tanks using a blower.

[@paulmaxwell8851]

It depends on submarine design: some have only forward and aft tanks, but most have centrally located main ballast tanks, with forward and aft trim tanks. 600 psi compressed air is used to surface the boat by driving water out of the ballast tanks. This is standard practice, not just in emergencies. Once on the surface, a 10psi blower system pushes outside air into the tanks to finish the job and conserve compressed air. The blower system cannot be used while submerged, of course, as there is no source of air.

[@mrt1r]

@@paulmaxwell8851 To clarify, specifically the class of Submarine she was on works the way I mentioned. You are correct though that some configurations use HP air as a standard method for deballasting the MBTs.

[@stefthorman8548]

imagine if this was classified information, and you get court marshaled for this.

[@mrt1r]

@@stefthorman8548 Lucky for me, it's not

[@fasfan]

@@paulmaxwell8851 not sure where you get the "most have" info from. All submarines in the US have forward and aft main ballast tanks and trim tanks throughout. I believe old WWII fleet boats had ballast tanks along the sides of the hull. So I would say most boats (at leslast in the US) have forward and aft main ballast tanks.

[@xcx8646]

Fair play. This trip would have been amazing and fantastically interesting, but also incredibly scary. You did very well.

[@pascalmonett7457]

Diana, you're awesome. I find it incredible that the US Navy allowed a landlubber and a camera crew on board what I always heard was top secret hardware. Congratulations on your experience. I can't wait to see the next videos.

[@scotchsoda3165]

Did you notice the rose parade screen covers in the control room? Anything classified will be covered, or classified papers turned over, when an "authorized alien" is in the room.

[@n0tawhale902]

The Navy has had other KZbinrs like Destin from SmarterEveryDay on LA-class subs recently. Virginia is the new tech and they still classify LA-class tech lol. While refitted and updated, LA-class tech is 2nd-tier so just sleep easy knowing Americans have a whole new beast of tech youll be able to hear about in 40 years when its obsolete and we have the Trump-class fast attacks coming out

[@trashpandatrailadv]

I was on ICEX 2011 with USS Connecticut (SSN-22) and USS New Hampshire, and it was such a trip all the time. Ice camps, gps, light, etc. All a new experiences, and any mistake almost lethal. Hope you enjoyed the boat coffee and food.

[@daveemerson6549]

I was there on the New Hampshire. Thanks for the oxygen candles lol

[@johnlancaster119]

Wow - you are one lucky lady. I have spent 32 year on Brit boats (submarines) and never once did we take a lady to sea. You must be one very special lady. I really enjoyed your channel and thought that the video was excellent. Bravo-Zulu Vet submarine Warrant Officer

[@lucendi.]

With a moving home position you can set the home position of the drone to the radio controller (operator) and not the GPS position of take off. Rookie mistake.

[@MichaelKea8888]

WOW what an amazing Video Diana. You're such an inspiration :) Thank you for all your amazing content

[@DavidVerch]

I'm not sure I would call the change in hull shape significant when the sub is at depth. It certainly does change shape. We had a system where we had to clean out the heat exchangers when we were underway. We did this by removing a spool piece that was maybe 2 feet long. The flanges were sealed by an o-ring. When we were on the surface the spool pieces could be installed easy peasy. Important point the heat exchanger was installed cross wise in the hull. When we were at depth the pipes moved such that you could still put the spool piece in but the clearance was so small that it would cut the o-ring. We used chain falls and all sorts of stuff to try to get that piece in without cutting the o-ring.

[@goofyiest]

A very good story, and I really enjoyed the drone at the end! I love that you used a Russian sub silhouette for your explanations. A couple of items. 1) MBTs do not run the length of the ship. 2) Periscope, not parascope.

[@RTomassi]

Given the age of the video, I was sure I'd find this comment xD Thanks!

[@electronash]

I had to Google the word "parascope", just to make sure it wasn't some other variant of Periscope I hadn't heard of. lol (thanks to old classic movies like Up Periscope for reminding me of the correct spelling.)

[@masamune2984]

It’s so cool that you experienced those issues with the drone! Science and Physics are obviously all about failing fast, iteration, and solutions, and you don’t learn through things going just as planned, which sums up, as you and the Captain himself stated, the entire point of conducting excercises in the first place 😊

Dianna, what a great story about your time on board a US sub (amazing enough) but also to be in the Artic, really amazing. I am jealous of your travels. I got to spend an afternoon on a short cruise (off San Diego) but clearly, an overnight in the Artic is much more exciting. Sorry to hear that you are still suffering with Long COVID. I am so proud of you and your efforts on KZbin and I hope that you will continue to explore and report science and keep us posted on your adventures.

[@lanceferraro3781]

Thanks, Diana. I like to say that my job for 22 years in the Navy was to repair submarines after the crew screwed them up. How they broke some of that stuff I'll never know. Anyway, took me back, on a pleasant trip to my past. BTW, sea life does get into the ballast tanks and die. Going into those tanks when the boat is in drydock.... whew....killer. Is there a reason a Russian Akula class submarine was used for your outline drawing.

[@erikalanreed8198]

Yes, any tech info blabbing is a big no no on our own subs. So the only alternative is to blab on another nations published info.

[@Str1tter]

i guess she did not know what kind of submarine it was. It just looked like one so it was used. 😀

I bet this video depicts the difficulty, dangers, and challenges of the deep a lot better than Stockton Rush did with his OceanGate submersible.

[@lindafoxwood78]

I was so scared by your voyage to the artic. I am glad you are ok. I am surprised the Artic has ice and the sub had to search for ice thickness that was less than 10 feet thick so it could break through. Wonderful video!

[@ajg1915]

It's been like 40 years now since I was last on a submarine. I used to work on them in Guam over at Polaris Point. We mostly saw the boomers (SSBN) and not the fast attack (SSN) that you were on. Great video. It brings back a lot of memories. Back in my day, the 600 class (Houston) was the current model. They were just getting to the (Ohio) class when I got out of the Navy.
