@@iguanapete3809 Thanks for serving. I was a Stryker combat vehicle driver in Iraq on a radio retransmission team. I only realized I wish I would've been a submariner years later. Oh well, I just think modern nuclear submarines are incredible. Completely self sufficient minus food stores, they're basically spaceships except they fly through an atmosphere which can be separated into potable water and oxygen, youre cut off from the world except for an ultra low frequency radio (Good for just saying "Hey, call me on HF"). And most importantly, they will avenge the United States if any nation is dumb enough to execute a first strike nuclear attack. I think our modern boats are more responsible for halting nuclear ☢️ war than any politician. Certainly these days.

[@REDPUMPERNICKEL]

@@Scarletraven87 There is a small error in narration at 7:40. The gyro does not "find" true north. After installation and during set up, the gyro is spun up with connected compass set to point at true north. Thereafter, so long as the motor keeps the gyro spinning, the gyro will keep the compass pointing at true north regardless of any and all submarine movements. (tiny errors, sometimes forward, sometimes backward, caused by bearing friction etc. tend to average out so compass error will remain insignificant for very long periods (which is of course the goal)).

@@jessdunaway8423 Yes, but those were very primitive, special-purpose vessels. The large, capable, and highly-successful Gato- and Balao-class submarines focused on in this video came from an extended development and testing program that ran through the 1920s & 1930s to develop the "fleet sub" concept. They were a huge advancement over the interwar S-boats.

[@davehageman7513]

@@rickh3694 I think the fuel tans were outside the pressure hull. So when fuel was used, it had to be replaced with seawater to keep the pressure equal. Wonder if they mixed to any degree, and if that was a problem.

[@BlitzkriegHD]

@@davehageman7513 Apparently, there were windows into the tanks that pumped fuel into the engines when it was running. Since the sea water was denser than the fuel, it would settle at the bottom of the tanks given enough time. When the diesel engines were running, the engineers would monitor the fuel levels through these windows, and keep a look out for the visual separation between the fuel and the water. If the water was getting too high (close to being pumped into the engine), they would switch the fuel intake to come from the other tanks, staggering the usage of fuel tanks so that while one was being used, the other could have time to “settle” with the sea water and allow the liquids to separate. In short, there wasn’t a major issue with sea water in the fuel, due to the density differences between the liquids. When one tank came close to being of issue, they’d switch to another one to give that tank time to become safe to use again. For reference I just googled “diesel fuel mixed with seawater submarine issue”, and I’m paraphrasing a forum post I found on a submarine enthusiast site (who knew those existed!)

In World War II it was the scariest fighting condition imaginable because days into the war we realized that the fancy new torpedoes that had been developed for our subs, destroyers, and torpedo bombers (The Mk. XIV) Was defective, the submarine fleet deployed to fight a war with a weapon that would not maintain depth properly, would not detonate when fired under an enemy ship (Magnetic detonators of the day were very unreliable), would rarely detonate when fired in contact detonation mode, and would occasionally wheel around and bounce off the hull of the boat that fired it (And this problem persisted past the redesigned detonators and has been attributed as a likely cause for some boats never returning). Any sailor that maintained their sanity fighting in those conditions is one tough SoB.

For a short video, this was an outstanding intro to the WWII American Gato and Balao class U-boats. Two machines the German type 7 and type 9 U-boats did not have that the US did was, 1st, a fresh water condenser that made fresh water out of sea water allowing the crew to actually take a shower once in a while, and 2nd , air conditioning. Neither were luxuries in the Pacific. A 1940's U-boat could not carry enough fuel and fresh water to keep the crew alive in the tropical heat. Given the vast distances they sailed it was a required device. Even with a fresh water maker they had to take a "navy-shower". The AC was installed mostly to keep the air in the boat dry so that electrical failures, and fires, were reduced. Even with AC a WWII U-boat was an uncomfortable ship. Which is why I was a surface navy officer. I'll admit it- Subs scared the hell out of me.

[@aurorasdawn4681]

What's a navy shower? Also, after viewing this video I'm curious about the differences between these American WWII U-Boats and WWI U-Boats as well as German XXI-Class U.Boats (which afaik are considered to be the first 'real submarines').

I earned my dolphins in 1970 on USS Hardhead SS-365, a WWII submarine similar to the one in the video. Hardhead was in the improved, deeper diving Balao class and was retrofitted/upgraded in the 50’s and again in the 60’s from the one in the video. We didn’t have a deck gun and our bow was more rounded like modern “nuke boats”. We had a tall “North Atlantic sail” over the conning tower and mast area. The sail was made of a steel frame with a fiberglass covering and was free flooding. The tall sail was to protect the guys on watch when on the surface in the stormy North Atlantic. There were many changes inside the boat as well including electronics that I worked on. All of these changes made it an HK (hunter killer) “Guppy IIA” submarine. Guppy stands for “greater underwater propulsion”. One key point in the video… We flooded tanks when diving to subtract buoyancy, not to add weight. We’d “drive” down with bow and stern planes then level off by pumping water back out. We trained often, stalking anything that came across our path. We believed …. Convinced, we were bad-ass hunters.

USS Herring. A few years ago I found a document that was a Japanese report of the sinking. I can't find it now, but according to the shore battery that sunk the boat, they hit the sub (it was running on the surface) with the first shot, which was in the conning tower. I believe it was something like a 5" round, which would have been devastating and probably killed the entire crew on the bridge and in the tower itself. A second round was reported to hit in the same area as well.

The pacing of the presentation is perfect and the script is simple, direct, and avoids getting swallowed up in technical jargon. I am an instant fan! One tiny factoid: the USN painted all of their subs black on the assumption that it would blend with the deeper hues of the ocean. But, near islands and atolls, where the water was very clear and often with a light bottom, it made spotting submerged subs easier. In the later stages of the war, they realized the issue and painted the subs in lighter shades as soon as possible.

I also remember playing with the torpedoes that were running to test their electronics. They would move their rudders as we walked close to them, pointing at us. As kids, we moved a lot - from Gitmo to Key west, to New London to Norfolk to Boston to Scotland to Egypt. Sometimes we'd move every other month. I always liked the submarine smell that my dad would wear when he came home -- I guess it was a mix of Diesel, sweat and Old Spice. I miss that a lot.

I served and qualified on a Balao class boat, and we had 16-cynder Gimmies in a V16 configuration. The aux engine in the after engineroom was replaced with the HP air compressors. Some pieces of equipment were placed in different locations on a Balao class boat. We never used the term "closed" for a hull opening or hatch, as it could be confused with the word "clothes", we only used to refer to a hatch or valve as being "open" or "shut." I was on the USS Blenny, which had been reconfigured to a Guppy-II class bow configuration for greater underwater speed, although it didn't add that much speed. As fresh water was at a premium, no washing machine, and we didn't have icecream lockers in afterbattery birthing area, it was in the freezer below the crews mess and galley. We had a sonar room down there too, for our special Puff Mounted sonar which had been installed on four Balao class boat, Blenny being one of them. We had no reduction gears between the main motors and props. The main motors, two of each of the four main motors were connected fore-to-aft on the same prop shaft, with direct speed control of each shaft and it's motors controlled by the controllermen at "the sticks" in Maneuvering room. The fwd head had a sanitary tank of it's own, as did the two side-by-side heads in afterbattery, but the aft torpedo room head had no sanitary tanks, and I think it only used while on the surface.

[@kanrakucheese]

They're so complicated, and thus expensive, the US never bothered to test its Mk 14 torpedo before the war because it cost too much. This was a bad idea as they either didn't work, or were more dangerous to the user than the target. This cost the US dearly early war, as they would have crippled Japanese shipping and brought the war to an end years earlier if they had a working torpedo (instead impacts were duds). Among other issues 1: It turns out things the primary detonation sensors were looking for actually vary quite a bit by when and where in the ocean you are 2: The firing pin for the backup detonator wasn't parallel to the front, so the shock of impact would bend it rather than slam it into to the primer to set off the explosives I recommend Drachinifel's video on them "failure is like onions" for the full story of how big a disaster it was

[@DavidOfWhitehills]

@@kanrakucheese But when they did get their torpedoes working the crippling of Japans merchant fleet was even more than what the uboats achieved.

Ours had a water sensor and it would slam shut if it got wet, if we were running a diesel it would pull air from the boat momentarily and make your ears pop and we'd use it to equalize air pressure like what was mentioned in this video.

Forward and Aft Torpedo would have loaded torpedoes through a hatch topside, and the torpedo would be slid down a removable rail system by crane, not too dissimilar to how it’s done on boats today. Desalination would have taken place below the conn, although most fresh water was fed to the batteries. In regards to snorkels, it’s kind of hard to say. There was the GUPPY project post-war that upgraded and refit several Balaos to include things found on the German Type XXI, like snorkels for example. However I can’t recall a specific example of an American boat sporting a snorkel during the war itself. It might have been discussed within BuShips, but was more than likely discarded for its complexity and adding another water ingress point.

[@jessdunaway8423]

interesting point about those sensors and alarms on the head valve (ventilation induction through the snorkel mast) SSN 713 the Houston was operating in heavy (state 4) sea's and the officer of the deck got annoyed at the momentary vacuum and annoying alarms on the mast momentary flooding... so he had the alarms silenced and the head valve locked open at periscope depth. the relieving watch made their depth 400 feet with out restoring the SOP line up.. immediately flooding the entire ship through a 21'' hole and caried through out the ship through the ventilation system. almost didn't make it to the surface as the capt only ordered a limited emergency blow of MB tanks and it start down again before reaching PD. if was terribly damaged and required a great deal of time to certify as seaworthy again. every one on board except a few chiefs to man below decks and top side watch were taken out to the pier and told they could leave the navy or the submarine service that very day...

I've been enamored with WW2 submarines/U-Boats for years but this just made a lot terms and concepts I've heard make sense for the first time. What a great video! Thanks!

[@arniestuboud]

The nave produced a very wonderful and detailed series of films now available on KZbin about the various systems of these subs. You need to check these out too.

[@GamePlayShare]

One of the best videos that shows submarine structure

[@verumpraevaleat8177]

just love this series of videos. Being a 60's child I was hooked on those "see through" books that showed you how stuff worked...these videos give me the same feeling I had as a kid paging through books of 3d see through pictures.

[@paulthew2]

You're in awe? So am I....at how good this was. Fantastic work!

[@RivetGardener]

What an excellent tutorial, you all have done a world class job! Helped me understand so much better the stories and recollections of submariners during WW2. Thansk you for that. I am amazed how we made such ships way back in the 1930's and 1940's....what a miracle of advanced technology. Just wonderful and so easy to comprehend for a non-submariner. Airborne infantryman here who has been fascinated with submarines.

[@asintonic]

To imagaine the complexity of creating and building a u boot with no computers or programs. Amazing

[@thomast8539]

Slide rules and people that could think about complexities, had the foresight to anticipate potential problems and develop solutions to fix those problems. And now we have millions of people with magnificent tools in their hands, but don't know how to think, ask questions and find the answers their own questions by using those same tools.

[@John-ws5oh]

Wow😮 I was glued to it. It's totally awesome,

[@DocKirk-e1x]

I have now viewed two of your videos, the SR 71 blackbird video and this one. The degree of research that you perform to provide, these videos is beyond reproach. You speak, intelligently, yet not arrogantly, confident, yet humble. I have just become a fan of your videos and will continue watching more of them. This is the kind of knowledge that I appreciate. Thank you for doing these videos.

[@harpomarx7777]

Torpedo room hatch does not lead to the bridge; it leads topside. It's an escape trunk. There's also a torpedo loading chute in the TR and after TR. The screws counter-rotated. The 40mm guns were forward and aft of the SAIL, not the conning tower. After planing to the surface, the diesels were started and their exhausts could be routed to the main ballast tanks to expel the seawater inside them, thereby conserving air in the blow banks. It took hours to recharge blow banks with high pressure compressors, so this was a good strategy called "surface without air". It also created an oily diesel residue inside the ballast tanks, which slowed corrosion. Air for the diesels first ran through the rest of the boat to ventilate and cool it before making its way to the engine rooms. These boats were quite hot and humid and fresh air coming through the vents and doors throughout was very much welcomed when the diesels started up. The diesels could also be deployed to remove smoke from a specific compartment in the event of a fire after it was extinguished.

[@animagraffs]

I'll include these details in a corrections thread, as per usual with the channel. Really appreciate such in-depth knowledge!

[@andrewsparrowhawk1637]

Wow I must say this video is absolutely incredible. The level of detail and explanation is remarkable. You have certainly painted a picture I will never forget. Thankyou for all your hard work.

[@gabbou2836]

I'm a huge fan of The Silent Service series (1957-1958) on youtube and watching your video about the fleet boats made me feel like I'm an actual crew member onboard. It was that good.

[@lancethompson6839]

Wow, excellent explanation and illustration. Thanks!

[@diddlethepoodle4812]

Great presentation. Absolutely knowledgable on all hands. Excellent channel. My grandfather was a pipefitter and then draftsman at Electric boat from the 40s to the 80s. A lot of blood sweat and tears went into making those boats. A lot of men paid with their lives from asbetos including my grandfather.

[@unnatural_log6472]

More naval stuff please. Wonderful work!

[@GRvyBB]

Quality work! I was so excited to see this after the battleship video you did recently. Keep up the great work! Would love to see more sea-faring vessels!

[@paulcooper3611]

Thanks for post. It takes me back to the days when I served on the USS Picuda (SS-382). It had started life in 1943 as a Balao-class boat. It had been converted to a GUPPY II by the time I served on it in 1971. At that time it was the oldest commissions submarine in the US Navy. A lot of things had been changed by then, but the bones were still the same. I was on the decommissioning when it was sold to Spain as partial payment to a extension on the lease to the base in Rota, Spain. Thanks for the reminder.

[@PanamaDave]

Nice, Dad was on Bonefish SS582 out of Pearl at that time. Prior he was on Tunny, Tang, Wahoo

[@richmorvant9581]

Hey Paul, I served on Picuda from 71/72 also and remember you quite well. You were SK I believe, I was IC, Morvant, Richard IC3 (SS). I'm glad to see you're still kicking around. My wife and I were in Key West a year ago to celebrate our 50th and I can honestly say it was a much quieter little town when the Navy was there than what it has become today. Sure brings back some good memories. Take care, buddy.

[@paulcooper3611]

@@richmorvant9581 You may not remember me as well as you think, but that's okay; it's been over 50 years, after all. It was Jim Cooper who was the SK. I was the bearded QMSN(SS) Cooper who worked with Freeman and Gibson up in the conning tower. I married a girl who graduated from Key West high and went back to her 25th graduation reunion, so I have some idea of how things have changed. It's a real hoot run into a shipmate from so long ago.

[@richmorvant9581]

Sorry, Paul, I do remember you, Freeman, & Gibson, & standing watch in the control room as fwd aux electrician. My wife & I met onboard Picuda one Saturday a few weeks before decommissioning when we had the boat open for visitors. She's from Cincinnati & I'm from New Orleans but we managed to make it work with 2 grown kids and 1 grand daughter. Life's been good.@@paulcooper3611

[@lucabaehr99]

It is absolutely incredible how advanced these machines were in WWII already. Fascinating video!

[@markteaney8381]

These crew members are amazing. Wow 😮😮😮😮

[@gideonding01]

absolutely fantastic video. very informative.. well done Animagraffs team

[@david9783]

"Complex' could be used to describe not only the sub itself as an instrument of war, but also to describe every single PIECE of her. There is nothing here to be bought at Lowes or Home Depot. Once again, superb job done with your Animagraff! ( My favorite so far has been the 18th Century Battleship!)

[@mihy26]

Me: airliner first, then 18th century sailing ship ;)

[@uttamnarayan9477]

Really amazed by the amount of hardwork you have put in this video animation.

[@donnysarian]

Absolutely amazing presentation on these marvels of technology. I learned so much. Thank you so much! 👍

[@mosselyn5081]

My dad joined the USN in the late 40s and served in diesel submarines much like this one through the 60s. I remember eating an ice cream sundae in the (tiny!) officers' mess, and even getting to ride in the conning tower when they repositioned the boat from its debarkation dock to the ship yard, though both of those experience were on the USS Catfish, a Balao class sub. It was fascinating to learn more about the structure and functionality of those old subs. Thank you!

[@csbanki]

This is incredible. Both the submarine and the animation and explanation. Thank you so much for sharing these with us!

[@ayubirana]

By far the best of best video I have ever seen. Animagraffs videos deserve at least 1 Billion likes or more. Truly astonishing.

[@AtomicElectronCo]

Amazing how complex and sophisticated it was, not relying on any external devices but totally independent. I was impressed with the "live map" device. The math and engineering required is just unreal.

[@benoitlangevin7522]

The amount of skills, reaserch, dedication and knowlage to produce videos like that is simply out of this world. Awsome work put together to entertain end educate us. A huge thank you for your passion and work. Much appreciated.

[@bandit9902]

Excellent video..... Best breakdown of a Sub ..

[@ArthurNRasmussen]

Another spectacularly well conceived and produced tour of a very complex machine. Cannot describe how enjoyable it is to watch/study. Thank you immensely!

[@starzkream]

I have watched this SO MANY times. Thank you so much for doing this, I can tell that you put an enormous amount of effort into it, and it really came out great. Amazing job.

[@TheWickedReactions]

Excellent video as always. As a submarine nerd myself I found this to be incredibly interesting. Thank you!

[@caribooskidoo3997]

Three minutes in and I'm liking and subscribing. Will definitely be watching this more than once.

Nice, we want more of those, please... some aircraft carriers, battleships, whats next? Give some ideas in the reply :)

[@neo_265]

Stunning work and amazing to see how technically advanced these were.

[@abimmel]

Amazing production. I know this was said many times before already, but you both deserve a couple thousand more comments about the stunning work put into this

[@smudgey1kenobey]

Insanely wonderful video! I’ve been obsessed with submarines since I was a kid, so I’m gobbling this up. Thanks so much for all the effort you put into the animation and script! Fantastic!

[@overtaxedcitizen4975]

Amazing work here. Detailed and explained succinctly with fantastic graphics. Thank you.

[@vm-snss4910]

I served nearly 4 years on a WWII Balao class in the 1950s. Your work in compiling the info in the video was outstanding. I enjoyed the walk down memory lane. Thanks.😊 My boat, USS Guavina SS362 did not have the ice cream machine or the washing machine.

[@johnleonard5857]

Great video. I have only spent time on nuclear powered submarines but the principle design has not changed much at all. Great basic explanation of what happens in every compartment. I was unaware of some of the things they had on these boats. I knew the current version but to see what they had to use back then is just amazing.

[@briandstephmoore4910]

We need every generation of warship and vehicles! Also a tunnel boring machine one would be awesome! The amount of detail and the visuals alone are top notch! This is freaking amazing to watch! And even better to replay while passing out lol

[@N5505KD]

This video was great! I work at the Intrepid Sea, Air & Space Museum in NYC where we have the USS Growler guided missile sub. Growler was built a decade after the Second World War but still retained a lot of tech from the fleet boats of that prior era. Much of your virtual tour is exactly the same to what we discuss in our sub, and, as such, I can also confirm your accuracy! I also learned a number of things about certain specifics (particularly the inner workings of the gyroscope/master compass), so thank you! I am going to pass this video on as a great learning tool for our floor staff. Very well done! Keep up the great work!

[@Subdood04]

Was a Submariner for 20 years on 4 Nuke boats. Got my Dolphins in Oct 87. This is a great job! We were cognizant of the fact that we stood on the shoulders of giants among men. The ones who came before.

[@MrColins710]

amazing detailing, very complicated, respect to the engineers who developed this submarine

[@lepusmalignis1628]

I've always loved the Gato/Balao class submarines. I snagged diagrams of both classes, and they are just incredibly complicated machines.

[@DanielHallmark]

This is an amazing video! The amount of detail included and professional production value is astounding. Like you, I am in awe of the engineering effort that went into packing all of that capability into such a small space, and the mechanical computers are an inspiring story all by themselves. Kudos to the men who designed, built, and operated these machines. Awesome job! Thank you for the video! I'm going to show your video to my children before we go tour the USS Drum (SS-228) at the USS Alabama Battleship Memorial Park.

Thank you for this excellent video and for the corrections made by experienced individuals!! I would like to add that my dad built (welder) Gato class subs at Manitowoc shipyards and served in the US navy on ARD29 a floating drydock in the pacific repairing ships and subs during WW2.

[@curtdilger6235]

You continue to produce amazing, inspiring, and engrossing videos. Pixar for adults. Your use of animation optimizes its teaching potential, and serves to demystify these wondrously complex, habitable machines that are worlds of their own. The grace of the camera movements, the logical order with which you describe the components, the subtle transparency employed, the editing, and narration all blend seamlessly together to create a presentation that is clear, educational, and entertaining. I especially enjoy the vertical torpedo of coffee. Cheers and Congratulations again for your fine work. Regards

[@ohasis8331]

So what we can conclude from this very well put together and informative video is that a WW2 submariner's life would have been a pretty miserable affair.

[@alaric_]

Cramped, cold, smelly, mostly dark and the death is at best quick if the hull implodes and at worst, a slow drowning... Compared to the average grunt in the eastern front: lots of space, digging, mostly wet, cold or both, marching and then more marching, digging, intense fear for days and weeks in one go when assaulting or defending and then little bit more digging. Tank drivers: cramped, cold, insane noise, practically blind and quick death is ammo rack going off, slow is burning slowly inside the tank. No matter where you served, it was shitty job. Well, officers in the HQ had it pretty good but other then that... War sucks (to put it mildly), for everyone and everywhere but naturally each section thinks the other soldiers are having it easy :D

[@petezereeeah]

​@@alaric_80 percent of German submariners during WW 2 never came home. Absolutely staggering.
