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.

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.

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 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.

[@johnvictorengland7703]

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.

Do you know why they called the diesel subs 'pig boats'?

The crew would usually enjoy the at sea swim call for an opportunity to clean up.

Is the diesel engine being used below sea?

[@TheSchmed]

Ƀɹyan Peazone nope, used to recharge batteries and for propulsion when not submerged.

[@H0kram]

It definitely can! The schnorchel allows it to be used at telescopic depth. Air-independent propulsion allows modern diesel electric subs, to use their engine at any depth, using different technics, from liquid oxygen to fuel cells. It can stay submerged for weeks while running on diesel, and produces very little noise compared to the nuclear engines and their cooling system.

[@btpcmsag]

Bryan Peazone -- To use diesel engines they have to A) be able to expel the exhaust gasses, and B) consume fresh air that would also be for the crew to BREATHE. So with this level of technology 3,000 psi is the highest pressure on board the sub. Therefore, presuming they can pump the diesel exhaust gasses out of the sub at 3,000 psi, it would be impossible to run the diesel engines any deeper than 1,250 ft. depth, nor would it be possible to blow ballast tanks deeper than that since the ambient seawater pressure would be greater than 3,000 psi. So the submarine would be virtually STUCK down there forever. IOW foundered. In practice, however, there is probably a factor of safety they use so they would never try to operate the sub deeper than say 1,100 ft. And they probably can't run the engines that deep either since the pumps they use to compress fresh air at the surface would not be pumps they would want to get contaminated with diesel exhaust gasses. Of course, when it's a matter of survival, it would be better to LIVE and have to breathe diesel fumes for a few days than to DIE because you can't move and you're being depth-charge bombed for hours on end. With the advent of "liquid oxygen" the pressure limits are all different because you need over 20,000 psi to contain liquid oxygen.

[@wolf310ii]

@@btpcmsag 3000psi are 206bar, 1250ft are 381m, in 381m depth the ambient seawater pressure is only 38bar (551psi)

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.

always wondered, when sub uses compressed air to empty ballast tanks to surface, that air is lost to the atmosphere, if the sub was to dive again again in a hurry how is the compressed air replaced for the next surface, had me perplexed for years.

[@DerH0ns]

@NINJAMAN420 But it'll draw in the air meant for the crew and also lower the pressure inside the hull, it's more likely that the air tanks contain more air than is needed to surface once.

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.
