I love the "old school" documentarys. They are so much more informative and light on overdramitised video sequences and junk facts. It's really too bad these days the priority of documentarys is more "being nice to watch" than actual information. Thanks for uploading this!
@MikaelS....I can’t speak for Markus, but I am, and I agree with his assessment. American videos are so over-sensationalized, we get over stimulated and need more and more and more...it’s nice to get back to some simplicity, and NO “narrative”.
they also use proper english grammar, and they wear proper clothes and shave their faces, comb their hair, and refrain from vulgarity. Plus they don't show footage of the cameraman or backstage, and they don't follow the narrators and film the backs of their heads, which is very common now.
I love how this actually explains stuff in a way that is satisfying enough in itself. No artificial effects, drama, or misplaced attempts to create tension.
I love these old timey explanation videos! Thorough as they are simple. You can come in with any knowledge of submarines and learn something new. We need to bring this style video to the modern age, not like those certain docs that are a little too over the top
Gotta respect the engineering of the era. Everything had to plan and manufacture from scratch, without computers/CAD/CAM. So many things to consider and plan to make it a ship and a war machine.
@@eaglegrip6879 lol even the outhouse was a complicated conction of pipes the germans once sunk one of their own subs because some sailor turned the wrong valve to flush. talk a bout an backwashlol.
nothing changes, now we have more sophisticated tools, but we also make more sophisticated things, and they based on prevoius tech as we rely on theirs, its civilization development
All slide rule and crude mathematics. Also the SR71 was built the same way. Groundbreaking engineering achievements. Today the software does all the job..
This is a great video! Shows the complexity of a submarine. Even though our modern nuclear powered submarines are much more complex in many ways, the fundamentals are still exactly the same!
Fantastic video, I could watch these all day, nostalgic as well reminds me of my years in the air force when we would often have these documentaries when learning about equipment. Thanks for the upload and keep them coming.

Awesome video! Need to start a TV network for these types of videos.
Remarkable amount of engineering gone into these boats. I highly recommend playing a WW2 sub sim like Silent Hunter 4. Nothing quite like the feel of swimming around the pacific sending cargo and warships to the bottom.
@@youhavenoprivacyandownnoth8289 aah, but its not a WW2 subgame. I could think of a far more arcadey subsim than SH4 (it's crash dive but its also pretty fun). Also of ur looking for a new take on subsim, i suggest you try UBOAT, its available on steam.
One can only marvel at WW2 technology(same goes for the 50s in case of this video). In fact, any technology from 1910 to 1960. It’s manmade, it’s tangible, out in the open. There are dozens if hinges and levers that all make stuff go. Just looking at something could tell you how it worked. And it’s all made by human hands. I once spoke to a gentlemen who renovated a bunker from the 50s. The ventilation system had a fan that was so balanced the thing was still turning when he found it. It had been in perfect sync for over 50 years! Now it’s all covered by a wall or hood. Out of sight, out of mind. No wonder there’s a shortage of technical staff. We aren’t exposed to technology like we used to be. Our kids are never exposed to engineering, so I don’t blame them for not choosing it.
When my dad left the RAF after his national service (he was discharged on the day the King died, 6th Feb 1952) he had an RAF handbook. It had many "cutaway view" drawings . I read that book until it fell to pieces.
It's really useful that old school was much better on those days I still remember the teacher uses sush films to help him making it easier for us on the 70's
old school documentarys are magically capable to keep you watching quiet and concentrated on the main heart of the subject. I miss this way of teaching. Nowadays if more about the Wao affect and distraction. pity
Man the engineering alone is impressive, let alone the use of chemistry to integrate the diesel engines into the systems of the ship like the hydraulic. Not to mention how navigation must be done while completely submerged.
Those Guppy conversations were influenced by the Type XXI U Boat. With the ability to stay under water longer via the snorkel, there was no real need for the deck and bridge armaments. Also, the sail structure that housed the shears reduced the drag that was present on the earlier conning tower/bridge configuration.
In general, the principle of horizontal movement of submarines is based on the principle of buoyancy developed by Archimedes. When the ballast tanks are filled with water, the overall density of the submarine hull increases so that the submarine descends to the seafloor.
I have wanted to build my own sub since i was a kid. Now that ive seen "Euronaut" and the other personal subs built i know it can be done. Now the only issue is money and lots of it.
what did they mean when they showed an image of a submarine or some type of platform literally carrying a cruiser ship? was it literally that or didb i miss something? and if yes how and why would they do that? i would really apreciate it if you answered, it made me very confused..
leo roys what did they mean when they showed an image of a submarine or some type of platform literally carrying a cruiser ship? was it literally that or didb i miss something? and if yes how and why would they do that? i would really apreciate it if you answered, it made me very confused..
June 1939: British submarine HMS Thetis floods and sinks while conducting diving trials in Liverpool Bay with 103 men on board. The crew keeps the stern afloat for several hours, but only four sailors manage to escape and avoid suffocation or drowning.
Submarines are designed to be slightly negatively buoyant when submerged. This means that they are slightly heavier than the water they displace. Ballast tanks, located in the hull, can be flooded with water or pumped out to control the submarine's overall buoyancy
Maybe never made a name for himself -- I've never seen a name for "narrator" in these old WWII documentaries. Perhaps he was like Tommy Tedesco, legendary guitarist, who never made contracts so he could collect residuals, now his sons are paupers.
@@btpcmsag ….well, if his sons are paupers, that's on them, not on him. Sure, if he had handed them bags of money then they might not be poor, but...those same sons also have the freedom to earn their own way in the world. You want money? Go out and get it for yourself, not wait for handouts from family or anyone else. Sheesh. Today's generation...
All these amazing safety and redundant features still didn't save the Thresher, and I am sure safety features only increased in the time between this and nuclear subs.
@@servicarrider I know :) It's like when something says "lifetime warranty" Its the lifetime of that product. Unlimited in this case would probably be longer than the life of the people on the boat.
A more accurate figure would be 20 years life before a reactor requires refuelling. Nutritional requirements of crew being left as the last limiting factor re length of voyage, although their sanity might be pushed if they were asked to spend multiple years at sea with only each other to talk to. Some things that might interest you: - water purification second to none (being distilled) - other than emissions from construction, no emissions or pollution generating through their working lifetime - the US Navy has never lost a sub to reactor failure or has there been a serious reactor-related incident while in operation, an exceptional safety record
Do you know why they called the diesel subs 'pig boats'? Because the boats distillery could only make so much fresh drinking water, that was used mostly for the cooks - thus leaving little for showers, which tended to make the crew (at times) live like a pig. The crew would usually enjoy the at sea swim call for an opportunity to clean up.
These were Brave men sailing into war's many dangers with the greatly limited technology they worked under and the lack of the now huge safeguards every modern submariner enjoys. Would the war be won without their (and the airmen's) special brands of skills and courage? DOUBTFUL!
In today’s modern submarines, the “conning tower” is no longer located atop the main hull. The “conn” is now in the control room and the empty upright “tower” structure is now called the “sail” or what the Europeans call, the “fin.”
Flak Jack Ed Well, true, but I mean if you couldn’t bring the periscope back there with you that wouldn’t work at all. My guess- through either very primitive digital technology (developed DURING the war by Alan Turing) or a highly complex set of mirrors and that could simply detract the light to wherever it needed to be. One a mechanical advance, the other a true breakthrough in science. The post war is absolutely fascinating and stocked with these innovations everywhere you look. Contemplate that, will you, just for a moment?- that it was incumbent for millions to starve, be tortured, humiliated and die, their lives stolen and emisserated, for such progress of the kind that makes like easier, more pleasurable, extends its length for those left behind. Etc. does that seem like a morally balanced trade? I don’t know. I really don’t know. In any event, pointless to dwell on it. It’s the way it happened. No arguing with that.
The very idea of being confined in a submarine would no doubt drive me bonkers, but so would a spacecraft. I like to read about OTHER men doing this stuff but it's just too fantastic to imagine actually doing it myself. It's kind of the same thing, really, but opposite ends of the spectrum: in a sub you get crushed to death but in a spacecraft your blood boils in a vacuum and you die of blood clots in the brain, heart and lungs. Ever wonder what a dead body looks like after dying those ways? Creepy.
I dont think so. The numbers are quiet bad for a post WW2 Submarine. Comparison : the Sub in the movie , autonomy submerged full speed 10 miles , slow speed 100 miles. Now the numbers of Typ XXI (german , last model to see action) , autonomy submerged 8 knots : 120 miles. 3 knots : 487 miles , full speed submerged 16.5 knots. Looking at the performance , in the movie they describe a Gato-class US-Sub. Another difference , the german XXI had a semiautomatic reload system fot the torpedoes. Could reload the 6 front torpedoes in less than 30 minutes. In manual loading you need this 30 minutes only for the first torpedo.
This looks like a Narwahl class submarine and they were commissioned in the late 20s and early 30s and decommissioned after WW2. I was able to track down this exact submarine and she was laid down on the 2nd of August 1927. She served in the battle of Midway and attacked Japanese cruisers in said battle. In total she served in 14 patrols before she was decommissioned. What a beauty.
Suggestion; just curious about refloating technology during an ERP sinking situation. How abt designing a refloating technology installed within for activation during an emergency sinking situation.
I am trying to design a submersible ship, an ark so to speak which is airtight and can take the pressure of huge waves. Looks like this video maybe useful.

Awesome!
Regards to you, I served on SSBN-642 twenty years later, Peace be with you, Ciao, L
Awesome! (for a bubble-head)
Thank you sir!
What a complex piece of machinery. The real mind blowing part is they did it all with slide rules.
A good slide rule and operator will give you incredibly accurate numbers. Something like 0.0001 . Or 1 in 10 thousands. Or even better if needed.
The mind Blowing point is They Went to War in these Tin can's
I have plan to build submarine DIY, this information really useful to build with some awesome features.
Much appreciate it.
So do I I love the narration of the program
Great video, never realized the subs systems were that complicated, even more crazy than submariner had to have a working knowledge of all the systems
Remarkable amount of engineering gone into these boats.
I highly recommend playing a WW2 sub sim like Silent Hunter 4. Nothing quite like the feel of swimming around the pacific sending cargo and warships to the bottom.
Internetspaceships great game
arcadey compared to dangerous waters.
play that if you want to operate a real sub.
@@youhavenoprivacyandownnoth8289 aah, but its not a WW2 subgame. I could think of a far more arcadey subsim than SH4 (it's crash dive but its also pretty fun). Also of ur looking for a new take on subsim, i suggest you try UBOAT, its available on steam.

In today’s modern submarines, the “conning tower” is no longer located atop the main hull. The “conn” is now in the control room and the empty upright “tower” structure is now called the “sail” or what the Europeans call, the “fin.”
Interesting. I didn’t know that. Is that because with digital technology the periscope doesn’t need to be located directly above its viewfinder?
Matthew Newton, That is possible. Another reason may be better communication between the conn and the control room.
Flak Jack Ed Well, true, but I mean if you couldn’t bring the periscope back there with you that wouldn’t work at all. My guess- through either very primitive digital technology (developed DURING the war by Alan Turing) or a highly complex set of mirrors and that could simply detract the light to wherever it needed to be.
