This U.S. Navy Training Film is about the basic WW2 submarine structure and systems. It is a description of the pressure hulls, tanks and super-structure.
The submarine shown at the end of the film is the USS Tusk (SS-426), a Balao class submarine. She was the only ship of the United States Navy to be named for the tusk. Her keel was laid down on 23 August 1943 and she was launched on 8 July 1945. She is one of the last two operational submarines in the world built during World War 2.
The Balao-class submarines:
The Balao-class was a successful design of United States Navy submarine used during World War II, and with 120 units completed, the largest class of submarines in the United States Navy. An improvement on the earlier Gato-class, the Balao-class submarines had slight internal differences. The most significant improvement was the use of thicker, higher yield strength steel in the pressure hull skins and frames, which increased their test depth to 400 feet (120 m).

Thank you for your generosity!
You prolly dont give a shit but if you're stoned like me during the covid times you can watch pretty much all of the latest movies and series on InstaFlixxer. I've been streaming with my gf for the last few months xD
@Dangelo Odin yup, been watching on instaflixxer for years myself :D
Some serious engineering went into these boats... truly amazing.
We would be able to search up how to build a submarine with internet if we had the men and tools but the fbi would go to town on us The human body and brain is capable of great feets

My father was the mechanic who operated the diesel engines on the Nautilus during WW2. I never knew the workings of these subs and after watching this video, I have an awe over the complexity of the total system. I only wish he was alive now so I could ask questions about the operation and his involvement. Like most veterans of WW2 he never spoke about the war. Thanks for your service Dad.
Was your father on Nautilus during Midway?
My grandfather was on a sub during the war, too. These subs are pretty amazing, as the men on board had to be, too. It's really fascinating to tour one, or more, if you get the chance. Unfortunately, my grandfather's boat is on Eternal Patrol, all hands lost.
The difference between these boats and the ones today is astounding. It's well worth it to tour one of the newer ones now, and to see the transformation. The quarters are still pretty tight, though!
@@paigetomkinson1137 Yes, he was on the Nautilus, 168 during Midway. I did go into one of the older subs which was on display somewhere and it was very small.
@@lorettacaputo6997 That's amazing. What your dad, and my grandfather, did was heroic. It wasn't every sailor who could do submarine duty. Part of the challenge was that smallness of the boats, not everyone could deal with it, as I'm sure you've realized from being on a sub.
Thanks for replying! Enjoy your summer. 🙂
It is interesting how the more directly engaged one is in war fighting the less boastful or haughty one is about their military service.
Reservist, rear echelon, non-combat types seem to consistently make their affiliation with the military a much larger part of their public identity
the engineering that went into these in the 1940's is unbelivable
The mystery of the workings of a submarine revealed without a single polygon or sprite. Love it!
If someone tells you that WW2 submarines were very basic in construction, show them the best video on said topic.
As a volunteer with SS-10, the Batfish, at the Muskogee War Memorial Museum Finds like this are a great help in my understanding of the systems of a submarine.
Thanks for your volunteer work!
My grandfather was an officer on many subs during the war and ended his career on the batfish from June 1959-June 1961. I am so very proud to be his grandson.
I enjoyed this video thanks for posting. I served aboard a Guppy2a boat for 2 years in 1968 &69, the USS Trutta SS421. Almost exactly like this boat. I worked in the after engine room and was the "Fuel King" for most of that time. The video brought back a lot of info and memories. I was transferred to a Nuke boat USS Will Rogers SSBN 659.
My oldest brother was a Sonar tech on the HardHead and was a Sonar Chief on the Pargo 650. I went the other way and was in a P3 Squadron.
@@Chris_at_Home me too! VQ-1, VP-17, NRL, VXN-8 and finally a flight test engineer on them.
Your efforts are appreciated
Too bad they don't make similar training films anymore.
They probably do. But they're probably classified.
H K smart Man.
@@abyssalreclass the moderns arent made as well as the old ones, straight to the point
@@ainzooalgown7589 On what do you base that? Their safe diving depth is WAY deeper... I'd suggest that implies quality!
@@ainzooalgown7589 What the actual fuck are you even basing that on? The new ones arnt diesel electric, can go decades with out refueling, have way better weapons, way better sensors, stronger hulls enabling them to dive deeper, they can stay submerged for years without coming to the surface, better complement of men, dude shut the fuck up. No machine from ww2 is superior to modern day machines, get off your fucking ww2 hard on.
Enjoyed the "film". My father served on the USS Sea Dog SS401
Love WWII subs and this video is so good. Thanks for uploading. Just amazing. This has made my Monday.
Props to the guys that knew these systems and operated/fixed them while serving on duty. (No pun intended on the "props" part)
You are correct these are WW II subs reworked. 1968 I saw a few of them in Japan and they had a more streamlined conning tower similar to the Nautilus and were called Guppy II's. Probably at the end of their service life. All of them were tied up at the not so nice docks while the nukes came and went with bands playing and a lot of fanfare. That was at the Yokosuka Naval base.
cool. now i can finally have a nice sunday stroll in my gato-class submarine
Hey I've got an idea! Let's build a stunningly complex boat that can go under water. Let's use any computers to design it or control it either!, "That sounds crazy! Who could possibly be smart enough to operate it?" Teenagers! But we will give them a few months of training and a handful officers that are only a few years older than them to supervise them. Wow! We are standing on the shoulders of giants, very brave giants.
Answered a lot of questions for me.
well most of this went over my head but it at least explains what all those pipes and stuff you see everywhere are for
The pipes are for a variety of things. Ventilation, potable water, waste drains, firefighting water, ballast transfer, fuel...
Ever think about how all the pipes in a sub are open to viewing and access yet in shows such as Star Trek they are alwayscovered.
@@davidneel2083 well, Star Trek takes place in space, not water, and is in a world so advanced that capital is meaningless, teleportation is a reality, and you can get whatever you would desire in the push of a button. It might be safe to say that, with that level of tech, they might be advanced enough to keep utilities out of view
My oldest brother served on this class of sub in the 60s as a sonar tech.
Must have been an amazing experience, these truly were a prime example of American naval engineering during the Pacific Theatre and all associated operations in the Pacific
@@Leopard-tx5wj He was on the Hardhead and they were using it as a testbed for a new sonar system.
What a great accent the moderator has.
I was in just about the last sub school class that taught conventional submarines(1963).
Take a drink every time he says "tanks".
This is NOT a WW2 submarine. The giveaways are the sonar room on the lower level, the snorkel, and the GUPPY type sail. All post war.
In the title it says Balao class. But the thumbnail is the USS Torsk, which is still a WWII submarine, but it's a Tench class, not Balao or Gato, plus the Torsk, as it appears in the thumbnail, has a Guppy configuration, which was postwar.
Actually TORSK is what's known as a "FLEET SNORKEL". Note that the hull has NOT been streamlined and modernized. She only received a snorkel, and a streamlined step sail. Otherwise she is predominately as she was in 1944.
Snorkel, streamlined sail, higher capacity AC system, and a more powerful electrical system.
Das Boot sent me here.
Same here
Wow.
Do you know where I can find part 1?
I've tried numerous times. I can find no record of the existence of Part I, at least not on the Internet.
There's always a lot of talking about the U boats but I feel the US Submarine service was always a bit in the shadows. Those US boats were seriously bigger then the U boats. Ok maybe not the last type U boat..
Early hybrid engine tech
Nice movie has a lot of info, just thinking there is a lot of shit on a sub that could go wrong. but i still would love to go for a ride lol.....
Yeah, if you read any submarine book written by a sailor you're bound to see "today pump no.34 stopped working", "yesterday we had to fix the 12th cylinder of the diesels", "the ventilation system clogged up", etc. at least once or twice every chapter. Lol :)
Captain Cappy Yes, that's why the Navy created the Sub Safe program after the Thresher went down and why subs are so expensive.
GERMAN SUB CREWS USED SAILORS RACING TO THE BOW TO SUBMERGE QUICKER.
Welcome to the Naval Education &Training Command. Old Navy guy comment-
"SUPPLIES!"
Here I thought that all submariners were very particular in calling their vessels 'boats' rather that 'ships'. I find in most of these docs that the terms are used more loosely than strictly. Golly gosh gee, guess I've been wrong all this time, imagine that.
No, you are correct. They are called 'boats'.
I kind of skipped parts of the video trying to find the information I was looking for, so forgive me if this was covered in it, but there are two questions I was always wondered about diesel-electric submarines both then and now. Because the video didn't answer them, I'll just ask the comments:
1. How long could a sub stay submerged (not snorkeled, I mean completely submerged)? I believe I heard something about 10 days for foxtrot class subs, but was it less time in WW2? can they stay underwater *longer now? And what about in WW1?
2. What did they do for breathable air? I saw the part about the air tanks in the sub, but the video didn't mention if they were for regular air or not. I believe at least some subs use scrubbers now, but I'm having trouble finding out when CO2 scrubbing was invented. Did it exist in WW2? was it always used in diesel-electric/gasoline-electric subs (like in WW1 or prior)? Did they just store it in tanks like other air? Or could they not submerge long enough for it to be a problem?
*I'm talking about conventional diesel-electric ones, which most navies still use. Obviously subs that use nuclear power or some other form of AIP can stay underwater indefinitely.
RRW i think most of them could stay down for like 2 days max before they start getting low on air or the batteries get completely drained.
Essentially u-boats and diesel electric subs compared to todays subs are not really true submarines. A nuke sub can stay down for months and never surface. A diesel sub can submerge for a short time but eventually it has to come back up due to batteries needing charged or lack of air.
They could stay down for as long as the air holds out; how long exactly depends on the sub. German Type VII U-boats couldn't stay down more than about a day at absolute maximum before they start running out of oxygen.
Generally, air from the pressure tanks stayed in the pressure tanks; the only air that was actually accessible for breathing was whatever air was inside the pressure hull. CO2 scrubbers were used to keep the air breathable for as long as possible, but didn't last forever; not only did the scrubber cartridges eventually reach capacity, they also didn't return oxygen to the system and were only good for removing carbon dioxide.
Important note: modern subs, whether nuclear or diesel-electric, can produce their own oxygen supply by various methods; historical subs could not do this and were stuck with whatever oxygen was inside the pressure hull.
@@yetanother9127 I've seen reports that O2 tanks were used to supplement the CO2 scrubbers in WW2 subs.
Basically, everything built before ~1960 would be called a submersible today because they normally operated on the surface and only submerged to defend against attack
CONFUSED AS TO WHY RELEASING THE BALLAST TANK AIR CAUSES THE SUB TO SURFACE NOT SINK?
I’ve never heard of a Balau-class sub. I know about Gato-class & S-class…I reckon the Balau came out after the Gato. 🤷🏽♂️
complicated engineering systems, the engineer in charge of these systems at sea has a difficult job. no wonder they are so hard to build.
AS THE WAR PROGRESSED IT BECAME OBVIOUS THAT SUBS ON THE SURFACE WERE FAR MORE LETHAL THAN SUBMERGED ONES.
USED THE SALT WATER FOR MANY OPERATIONS.
I will save you the 30 minutes. Fully submerged it runs on batteries and can dive to a depth of several hundred feet, or it can dive to periscope depth and use the air intake for the diesel engine. Otherwise it runs on the surface and runs on diesel-electric generator.
“Learnt so much, we will build new revolutionary submarines using what’s learnt from this video!” Kim Jong Un
Hats off to submariners. I don't think I could do it. But I was a scout, I doubt a submarine is any more dangerous than that. But something about the submarine just doesn't sit right with me.
I think it's the fact that in most other services, you can spend your off time taking a walk in fresh air. Submariners were confined inside the vessel without anywhere to walk around or checkout the scenery. You are constantly locked into the cramped quarters without so much as a window too look out of. You couldn't even tell if it was night or day. It takes better people than me to serve on those boats I'm afraid.
As a scout I’m sure you and very few others were responsible for your safety. On a sub EVERYONE is responsible for your safety, including the engineers back at base.
@@kaptainkaos1202 that is probably a pretty fair assessment.

Fajny film
😊💙💜💚❤🧡💗
That’s what always confused me, how do engines run underwater. They don’t, that’s why they’re diesel electric with batteries. Any of em every run the batteries dead underwater accidentally?
I like nuclear subs
This is all they show the entire crew, even mechanics, the rest you have to figure out. After the video they get sent out to sea. Wheres the red october training??
THINK FRANK SINATRA MADE A MOVIE ABOUT CIVILIANS MANNING SUCH A SUB..MOVIE'S NAME ESCAPES ME???
SORKELING?
these things sound like deathtraps alot can go wrong
3,000 psi is no laughing matter. Yikes!
the nuke boats have 4500 psi
I think Bubbell is canonical female currier.
WONDER HOW MANY SUBS SANK DUE TO A CREWMEMBER REVERSING A VALVE OR FORGETTING TO OPEN A TORPEDO DOOR.
I never understood how a engine could run under water. A diesel engine needs air. And I just don't understand the concept
Did you even watch it?? The diesel does not run when submerged, the batteries supply power to the electric motors. That is why they must surface and recharge... Not that difficult to understand.
@@Stillnapie no but thank you for telling me
Diesel runs from snorkle as submerged.
@@solarpower09 thank you
Did any subs ever drain the batteries too much before resurfacing? What happens if the batteries fail underwater? The anxiety of running out of electricity in a electric car is a lot to handle. This is like that but much much scarier.
TELLTALE OIL SLICKS...LOL
Jesus Loves You
You have seen the most important systems for the submarine but you’ve completely overlooked the maneuvering room which takes electricity from the generators all the batteries and delivers them to the motors for propulsion how long or if you could avoid that is beyond me probably ties in with your tedious voice.
Well, gee! I guess you'd better go back to 1955 when this was made and let them know. Bear in mind also that this was Part 2...chances are that other important systems and procedures were discussed in other parts. I, for one, was grateful to see such a rare film that at the time was only available to submariner personnel. I guess your lack of appreciation ties in with your atrocious punctuation.
