I can't even imagine how much effort should it take to meet combat reliability with this level of complexity. It can be achieved only with extraordinary high engineering and production culture.
@@PHOBOS1708 No torpedo in those was hugely reliable. And it was mostly failing to detonate, not going off early killing the crew. An issue which was helped tremendously by improved warheads, detonating more reliably.
@@jamegumb7298 Most german operational torpedoes were quite reliable after the technical issues related to the "torpedokrise" before 1942 were sorted out (that is the G7a(TI), the G7e(TIII) and subvariants + the G7e(TV)). I have never heard of any german torpedo "going off" early and killing the crew... The formost problem with the torpedoes was tactical, ie actually hitting the target.
the torpedo itself is the pinnacle of engineering. It is an incredibly precise and thoughtful mechanism of great complexity. The complexity of the systems is shocking, but it is also absolutely wonderful to think over technical solutions (it is a pity that such a miracle of technology was used to kill other people). The fact that the torpedo is a master of engineering is one thing, but the other thing is that your work on this presentation is a lot of effort and power of knowledge! I am shocked by the enormity of your work. I bow my hat down to the ground and I am shocked by the enormous wealth of your work !!! You are master!!!
"Its pity... other people". We would be still be apes if our brains werent capable to make the first axes, bow and spears to win of a more primitive clan. The modern human being is a filtrate or left over of an almost endless ammounts of strugles and hardships, where you had to outwit the other parties technological advantages. On the background, economics, healthcare and many other developments is assisting our chances in breakthroughs, the small little bits that make us lose or win. People dont grow faster and intelligenter brains out of its own or out of miracle. We had primiteves in europe, see the cave paintings in France, its the dumber part of our family that got wiped out. From a familly one child is doing better than the other one in school, and nature hardships, is selecting them to go trough and make he next generation or not. All what lives, overcame strugles, for it wouldnt exist in the beginning, and with such things requires offence, for there would be no food on your plate that way, perhaps we see animals not even as possible threats but see them mainly as food to consume. We lost the interest of thinking as them as fellow combatants, the only real danger left to us as animals (plants are also self living organisms, i dont think they would like to be consumed by vegetarians) are just other humans. Its a breakthrough in evolution, no other organism is achieving as much as we do, we outwitted our competitors, we wouldnt be alive otherwise. These machines belong to us, if not we would be overthrown eventually.
Awesome graphics. Tells completely and eloquently how much engineering and process goes into something as "simple' (by today's standards) as a 1941 torpedo. Great video.
As a Torpedoman in Uncle Sams' Navy during the last days of the Mk. 14, I was surprised to find that, other than propulsion, the control mechanisms and exploder were very similar in operation......excellent video
Nothing to be surprised by: American torpedoes were initially based on the design of the Whitehead (Italian) and later Schwartzkopf (german) torpedoes that was purchased by US Navy, which later copied them under license by E.W. Bliss Co. (I'm ignoring the Howell-torpedo and other creative american "torpedoinventions" during the late 18th century). Most effective torpedoes can be traced back to the original Whitehead-designs, so it's easy to identify the internal mechansims of most wet-heater torpedoes from ca 1870 to 1960.
You did a more than excellent job in both modelling, explanation of the different mechanisms and the procedures of (launching) a torpedo. Your videos are clearly underrated versus other channels.
I spent 3 hours marveling over this incredible feat of engineering in person at the Chicago Museum of Science and Industry and could not stop trying to decipher how it worked! Thank you to whoever put this animation together!
Incredible work - I can't imagine how much effort went into this video. Keep them coming. I'd be especially interested in seeing a FAT and/or LUT explained in such amazing detail.
This is an amazing video… thank u so much for the detailed explanation of how these torpedos worked. It’s way more complicated than I thought. Again great job
Thank you so so much! I was waiting ages to see how this one came out. I had no idea just how much maintenance was required to keep them heated and charged. Now when my crew in SH3 (with full interior) get tired all the time in that compartment, I will have more respect. I had no idea about the hydrogen either. I guess I never considered it. And you're the first person I've seen that shows me how the Vorhaltrechner interfaces with the torp. The only thing I'd love to see now is the steam powered A model. Thank you again!
Also one question, regarding the hydrogen. At one stage, during the animation, the hydrogen was removed by means of an extractor system during charging. But during the heating process, it just shows the LP compressed air being blown in, which shows the hydrogen being vented over the side. Where does this hydrogen go?
Hydrogen gas, mixed with the air in the battery compartment, is vented out of the torpedo though the vent valve (05:32) and into the torpedo compartment (torpedoes in the reserve storage compartments) or through the open torpedo rear doors. I shudder at the idea of leaving the rear doors open all the time, but this is what the Instructions imply. Then the hydrogen is extracted by the ventilation system and mixed with the whole submarine atmosphere, which dilutes it well below dangerous levels, until burnt up when the diesel engines are started.
Замечательное видео! Удивляет, как автор смог всё понять как нужно и так доходчиво объяснить весь процесс обслуживания, подготовки к бою и пуска торпеды. Наверное, она и вправду была такая дорогая, как описывалось в фильме "Подводная лодка". Жаль, что без русских субтитров. Мысленно жму автору руку!
Много где читал, что она стоила примерно как пол Мессершмидта. Теперь я понимаю почему. Твоюж мать, все привода и гироскоп оказывается на пневматике работают. Это что-то нереальное..
This is the 3rd video I watched today on US/UK wet-heater torpedos and this torpedo by far was a technological marvel of its time. Those Germans and their engineering know how always sets them apart. Thank you for the kickass background music 👍🏻.
nonostante sia un elettrotecnico non immaginavo che stoccaggio manutenzione e uso fossero così laboriosi e complicate . splendido video dove nulla e lasciato al caso , davvero bravo un notevole lavoro 👍
I was eagerly waiting to see German submarine torpedoes on this channel, this one didn't disappoint. Is there enough open source data to hope to some day see a similar animation of the G7a? How about models with more advanced guidance such as the Fat, Lut, or the infamous G7es acoustic torpedo? Thanks for your work.
I have no plans to make a G7a model as it uses the same parts (Gyro, Depth gear, servos, warhead and pistol) as the G7e. The propulsion is a straightforward compressed air - wet heater - 4 cylinder radial Brotherhood type engine that I have already illustrated in the British Mark 2 of WW1 model. I can see nothing new or radical about the G7a engine. What is interesting are the advanced mechanisms. I have hope of getting drawings of the FAT mechanism inside the torpedo, but despair of finding the torpedo LUT mechanism drawings. As for the G7es Kaunkönig T V, I don't have the drawings and anyway only 761 T V were fired of which only 112 hit (14.7%). Infamous? I would much rather model the US Mark 24 'Mine' (accoustic anti-submarine homing torpedo - Fido) from 1943 - if only I could get the drawings.
@@vbbsmyt Thank you very much for the detailed answer, really appreciated. Makes sense that the G7a would be redundant and thus not so interesting to model other than for completion/reference. Fingers crossed you do get your hands on the drawings for FAT/LUT mechanisms. As for the T V, I admit that "infamous" was over-blowing it considering its actual impact, especially compared to the Mark 24 which would be fascinating to see. (Any plans for this one, by the way?) My wording was more about its perceived danger, which as for a lot of late WW2 German weaponry (V-2, Hs 293, Me 163, Wasserfall...) was far exceeding its actual impact on the war - other than further draining scarce German resources.
@@vbbsmyt FAT and LUT manuals with drawings (I'd have to check what variants) are available in archives and museums (NARA, TNA, BaMa, Danish and Norwegian National archives and armed forces museums) - same goes for at least partly G7es(TV) "Zaunkönig" and G7es(TXI) "Zaunkönig II" torpedoes. Some private collectors in Japan and US have original german manuals as well.
Fascinating... Now i see why torpedo loading times took so much in Silent Hunter sim... :) Great video. That's a lot of work done by the author. Appreciated!
I don't stop to comment often but I just have to say - these are incredible videos. Absolutely love the torpedo series. I would love to see a USN Mk.14 (early war variant) and IJN Type 19 if you ever get up to making another wet-heater video. Seriously excellent work.
I've always thought the acoustic homing torpedo is the real apex of what could be achieved before transistors were in use. It's pretty crazy to think that already in WW2 there were fire and forget weapons!
Neat stuff, I had always assumed that when the tubes were flooded the water came from outside the submarine, never figured it was internal to the sub. Learn something new everyday :)
Electric torpedos but analog circuitry. Crazy how everything was pressure valves instead of wires and chipsets. It’s basically an analog computer. Lol the irony that this was a million times more complex than computers now.
I'm a software engineer and as such I know how complicated it can be to even tell your co-worker right beside you about your ideas of complex systems. I'm always wondering how stuff like that was and is quality checked and that it is not blowing up somewhere unexpected.
Manchmal hatten die Torpedo einen Defekt und sind im Kreis gelaufen. Wie ein Boomerang kamen sie zum U Boot zurück und zerstörte es, wenn es nicht schnell weg gefahren ist.
I finally took some time to study the video, and have taken the liberty to add some comments (UA-cam is not the best platform for giving feedback with only text...): 00:32 Just some additional info: The 26-cell 13T-210 battery had a combined voltage of 110V (the TIII used two batteries, while TIIIb and TIIIc had only one). Note that there were four "ausführungsforme" (I to IV) for the 13T-210 battery with different physical sizes and different design/installations of heating elements etc. The drawings in M.Dv.Nr 689 are probably an early variant (I would guess ausführungsform I or II). 01:02 Some of the translations are a bit off in my opinion... "Running distance setting" (Laufstrecke) is better than "Stop Range setting", and "Rudder Lock distance setting" (Sperrung) is similar better than "Rudder lock setting". 01:14 The GL 231/Z5 engine used in the G7e(TIII) and it's subvariants (as well as later G7e models) had these spesifications: * 1755 rpm: 91V, 950A, 72kW * 1590 rpm: 83V, 885A, 60kW Data is rated for an engine run-time of 5 minutes and 40 seconds. For the TIIIb and TIIIc torpedoes the speed was reduced to 17,7 kn with an engine rpm of 1100. 01:22 The three 5-litre airtanks in the aftsection were charged to 200 kg/cm^2 (that goes for all combinations of airtanks in Kriegsmarine torpedoes). Allthough 160 kg is indeed mentioned in M.Dv. Nr. 689, that's just as this pressure is to be used for reference. 05:42 The regulations pr 1941 dictated topping up the batteries every 5-6 days 08:12 The plate for shorting out the fuze is made of copper, not steel. 10:08: Shock-absorber is not correct: This is a damper/buffer, as well as an adjustment for the rudder-transfer (ie "fine-tuning" of the deflection). 10:22 You're using the term reducer, in stead of regulator? Maybe it's the same (I'm not english, but the "Regler für G.A." regulates the output, keeping it at a constant pressure). The "Regelstutzen" is not an airfilter. Admitably it contains a filter, but the purpose for this device is to give access for connecting an outside nozzle with prezzurized air to run the depthmechanism and the servoengine for mainetance-routines (the device and the filter has no function for the torpedo itself). 10:28 The function of the rudderlock is partly correct, but it's also in fact to force the torpedo down. The lockingdistance (sperrungstrecke) varies for the different torpedoes and wether it's launched from a submarine or a surface ship (the problem is worse for the latter, ie the need for a longer distance - typically almost 200 m for a G7a(TI)). Normally, the torpedo seeks upward until it has reached full speed and the depthmechanism is stable and working, and it will often brake the surface and "wake" for a brief moment. The depthrudder will be locked in a downward setting - typically at -10 degrees (for a wet-heater torpedo the lockingdistance also serves another purpose of emptying the engineblock of seawater and getting the cylinders moving). 11:11 The depthsetting is correct by counting rotations, but a dedicated tool is used for this purpose (gerät nr 500) not a T-shaped key. Depth-setting was depending on type of pistol and target (there were default settings for both mechanical and magnetic pistols against various type of targets), in heavy weather wave-height should also be taken into consideration. For a Pi1 mechanical pistol 3 m was a more typical depthsetting. 12:25 Regarding adjusting the gyroscope-angle: This is a tactical issue that I have limited knowledge on - especially in regards to the submarines. The feature would seldom be used on a larger surfaceship (were you'd adjust the angle of the tubes), unless you'd planned for it well ahead in your attack (it's simply a feature to adjust the torpedo's course after launch, and adds another complexity to your fireolution - of course not a problem if the submarine has a torpedocomputer with this option installed). 14:04 I'm not sure if this is as intended, but you're using the same colour for the 200 kg high pressure (again: Not 160 kg, and the lowpressure output should also be higher: 25 kg if I remember correct) and the low pressure air from the regulator to the servoengine. 14:35 I really like the gyroscope-animation - I find it hard to believe you did this by the 2-dimensional drwaings in M.Dv. Nr. 689 alone (kudos in that case...). Just some additional info: The Geradelaufapparat VIII (GA VIII) was the standard gyroscope used in all the german (naval) torpedoes, with some variants. The gyrowheel span up with the blast of 200 kg highpressure air as shown in the animation. The air was cut off by the valve after a delay of 0.25 seconds caused bye the pressuredrop in the sphere cavity. During that time the wheel reached a speed of 13000 rpm. After that, the wheel is kept running by the 8 kg feed (not 6), accelerating the wheel up to, and keeping it at, 21000 rpm. 18:21 The Pi1 (originally desiganted Pi-G7H) was first introduced in 1942, so it was not used in early torpedoes of any model (ie TI or TII). The Pistols used until 1942 was the Pi-G7AZ (mechanical) or Pi-G7MZ (mechanical/magnetic). For a TIII torpedo Pi1 was not allowed, so it would have been fitted with the the Pi2 from start. Some general comments: The color/shade of the aftsection differs from the rest of the hull. I'm not sure if this is intentional, or just a result of the graphic-program's generated curves (like the front of the warhead), but they should be identical. The different shades of the 5 hatches are correct, although should be opposite (ie lighter). I have yet to find out the reason for this - the hatches I have seen in real life have all been made of the same steel as the hull, and wouldn't differ, so I suspect they might actually have been coated with a paint or similar. The only reason I can think of might be to avoid having to apply grease, as these hatches have to be opened regulary for the different maintenance-routines/ batterycharging etc. The arrangement and details of the components in the enginecompartment varies between the G7e-models, and your variant is probably not 100% correct for the TIII as the M.Dv. Nr. 689 is a generic manual originally from 1940 (the TII), although revised and updated regulary (it would be interesting to know what source you have: A proper scanned edition from BaMa, or another version?). The torpedoes are not stored with pistols mounted in the warheads - these are mounted before loading. The pocket in the nose is closed by a lid until the pistol is mounted. The torpedo has two safety-tools installed in storage, that has to be removed before loading: The propellerstopper and the startinglever-inhibitor. I think most of the translations are a bit weird compared to the terms I'm used to, but I'm not english so I'm probably not the best "critic" on that topic and I have ignored most of those.
3:22 Right there I thought "Right, and now the torpedo magically slides into the tube, of course...." 3:28 And there I thought "Why did I doubt vbbmyt, of course it is detailed how the last part of the torped0 is pushed into the tube..."
when I saw that I was thinking "ok this is where the mate pushes the torp the rest of the way in", but nope, there's a mechanism for that. Also amazing just how much mechanical effort is required, nowadays it's all motor driven and computer controlled!
What a masterpiece! Each single mechanism explained in details. Huge amount of work but worthy.
I can't even imagine how much effort should it take to meet combat reliability with this level of complexity. It can be achieved only with extraordinary high engineering and production culture.

Uma engenharia incrível ,muito a frente do seu tempo. Eram e continuam a ser pessoas de primeiro mundo.
An excellent presentation. 😃👌👌👌👏👏👏👏
Astonishing. How this device is complicated. And it was 80 years ago'
I've always thought the acoustic homing torpedo is the real apex of what could be achieved before transistors were in use. It's pretty crazy to think that already in WW2 there were fire and forget weapons!
For me this would be a life's work.
Have no word, incredible, like usual!
Outstanding work, incredible!
Wow!awesome!so intricate,and ingenious!thank you, :)
And this is another reason why germans lost 2 World Wars. Thank you very much for these beautiful cinematics. Respect!
Magnificent. The Masterpiece!
Thank you, now i can make one
Thsi vid is why I keep coming back to youtube. There is so much crap here, but this is great stuff. Well done.
What a clear animation of how this worked. Great!
These videos are so fascinatingly detailed that given some time someone will try to replicate these torpedoes
Amazed by the fact gyrosensor and tilt-trometer in essence...
Excellent presentation. Thank u 👍
Lovely work as per usual. :-)
Boah, das war gut animiert und erklärt!
Neat stuff, I had always assumed that when the tubes were flooded the water came from outside the submarine, never figured it was internal to the sub. Learn something new everyday :)
Flooding from outside water would give away the sub on the SONAR (This does too but not that much)
Electric torpedos but analog circuitry. Crazy how everything was pressure valves instead of wires and chipsets. It’s basically an analog computer. Lol the irony that this was a million times more complex than computers now.
Incredible amount of hard work and technical knowledge to produce this video. Thank You.
can you do a video about the Type 93 "long Lance" Japanese torpedo? i was always fascinated by them
I cannot locate drawings, so NO
I love your works, never stop
I'm a software engineer and as such I know how complicated it can be to even tell your co-worker right beside you about your ideas of complex systems.
I'm always wondering how stuff like that was and is quality checked and that it is not blowing up somewhere unexpected.
Manchmal hatten die Torpedo einen Defekt und sind im Kreis gelaufen. Wie ein Boomerang kamen sie zum U Boot zurück und zerstörte es, wenn es nicht schnell weg gefahren ist.
I finally took some time to study the video, and have taken the liberty to add some comments (UA-cam is not the best platform for giving feedback with only text...):
00:32
Just some additional info: The 26-cell 13T-210 battery had a combined voltage of 110V (the TIII used two batteries, while TIIIb and TIIIc had only one). Note that there were four "ausführungsforme" (I to IV) for the 13T-210 battery with different physical sizes and different design/installations of heating elements etc. The drawings in M.Dv.Nr 689 are probably an early variant (I would guess ausführungsform I or II).
01:02
Some of the translations are a bit off in my opinion... "Running distance setting" (Laufstrecke) is better than "Stop Range setting", and "Rudder Lock distance setting" (Sperrung) is similar better than "Rudder lock setting".
01:14
The GL 231/Z5 engine used in the G7e(TIII) and it's subvariants (as well as later G7e models) had these spesifications:
* 1755 rpm: 91V, 950A, 72kW
* 1590 rpm: 83V, 885A, 60kW
Data is rated for an engine run-time of 5 minutes and 40 seconds.
For the TIIIb and TIIIc torpedoes the speed was reduced to 17,7 kn with an engine rpm of 1100.
01:22
The three 5-litre airtanks in the aftsection were charged to 200 kg/cm^2 (that goes for all combinations of airtanks in Kriegsmarine torpedoes). Allthough 160 kg is indeed mentioned in M.Dv. Nr. 689, that's just as this pressure is to be used for reference.
05:42
The regulations pr 1941 dictated topping up the batteries every 5-6 days
08:12
The plate for shorting out the fuze is made of copper, not steel.
10:08:
Shock-absorber is not correct: This is a damper/buffer, as well as an adjustment for the rudder-transfer (ie "fine-tuning" of the deflection).
10:22
You're using the term reducer, in stead of regulator? Maybe it's the same (I'm not english, but the "Regler für G.A." regulates the output, keeping it at a constant pressure).
The "Regelstutzen" is not an airfilter. Admitably it contains a filter, but the purpose for this device is to give access for connecting an outside nozzle with prezzurized air to run the depthmechanism and the servoengine for mainetance-routines (the device and the filter has no function for the torpedo itself).
10:28
The function of the rudderlock is partly correct, but it's also in fact to force the torpedo down. The lockingdistance (sperrungstrecke) varies for the different torpedoes and wether it's launched from a submarine or a surface ship (the problem is worse for the latter, ie the need for a longer distance - typically almost 200 m for a G7a(TI)). Normally, the torpedo seeks upward until it has reached full speed and the depthmechanism is stable and working, and it will often brake the surface and "wake" for a brief moment. The depthrudder will be locked in a downward setting - typically at -10 degrees (for a wet-heater torpedo the lockingdistance also serves another purpose of emptying the engineblock of seawater and getting the cylinders moving).
11:11
The depthsetting is correct by counting rotations, but a dedicated tool is used for this purpose (gerät nr 500) not a T-shaped key.
Depth-setting was depending on type of pistol and target (there were default settings for both mechanical and magnetic pistols against various type of targets), in heavy weather wave-height should also be taken into consideration.
For a Pi1 mechanical pistol 3 m was a more typical depthsetting.
12:25
Regarding adjusting the gyroscope-angle: This is a tactical issue that I have limited knowledge on - especially in regards to the submarines. The feature would seldom be used on a larger surfaceship (were you'd adjust the angle of the tubes), unless you'd planned for it well ahead in your attack (it's simply a feature to adjust the torpedo's course after launch, and adds another complexity to your fireolution - of course not a problem if the submarine has a torpedocomputer with this option installed).
14:04
I'm not sure if this is as intended, but you're using the same colour for the 200 kg high pressure (again: Not 160 kg, and the lowpressure output should also be higher: 25 kg if I remember correct) and the low pressure air from the regulator to the servoengine.
14:35
I really like the gyroscope-animation - I find it hard to believe you did this by the 2-dimensional drwaings in M.Dv. Nr. 689 alone (kudos in that case...). Just some additional info:
The Geradelaufapparat VIII (GA VIII) was the standard gyroscope used in all the german (naval) torpedoes, with some variants. The gyrowheel span up with the blast of 200 kg highpressure air as shown in the animation. The air was cut off by the valve after a delay of 0.25 seconds caused bye the pressuredrop in the sphere cavity. During that time the wheel reached a speed of 13000 rpm. After that, the wheel is kept running by the 8 kg feed (not 6), accelerating the wheel up to, and keeping it at, 21000 rpm.
18:21
The Pi1 (originally desiganted Pi-G7H) was first introduced in 1942, so it was not used in early torpedoes of any model (ie TI or TII). The Pistols used until 1942 was the Pi-G7AZ (mechanical) or Pi-G7MZ (mechanical/magnetic). For a TIII torpedo Pi1 was not allowed, so it would have been fitted with the the Pi2 from start.
Some general comments:
The color/shade of the aftsection differs from the rest of the hull. I'm not sure if this is intentional, or just a result of the graphic-program's generated curves (like the front of the warhead), but they should be identical. The different shades of the 5 hatches are correct, although should be opposite (ie lighter). I have yet to find out the reason for this - the hatches I have seen in real life have all been made of the same steel as the hull, and wouldn't differ, so I suspect they might actually have been coated with a paint or similar. The only reason I can think of might be to avoid having to apply grease, as these hatches have to be opened regulary for the different maintenance-routines/ batterycharging etc.
The arrangement and details of the components in the enginecompartment varies between the G7e-models, and your variant is probably not 100% correct for the TIII as the M.Dv. Nr. 689 is a generic manual originally from 1940 (the TII), although revised and updated regulary (it would be interesting to know what source you have: A proper scanned edition from BaMa, or another version?).
The torpedoes are not stored with pistols mounted in the warheads - these are mounted before loading. The pocket in the nose is closed by a lid until the pistol is mounted.
The torpedo has two safety-tools installed in storage, that has to be removed before loading: The propellerstopper and the startinglever-inhibitor.
I think most of the translations are a bit weird compared to the terms I'm used to, but I'm not english so I'm probably not the best "critic" on that topic and I have ignored most of those.
Awesome and informative with some great solid modelling.
Really great animation!
Amazing work!
Excellent video. Dam clever these Germans, but a very complex design!!!
German Engineering at its finest!
This is such a funny comment to leave on such an unreliable torpedo model
3:22 Right there I thought "Right, and now the torpedo magically slides into the tube, of course...."
3:28 And there I thought "Why did I doubt vbbmyt, of course it is detailed how the last part of the torped0 is pushed into the tube..."
when I saw that I was thinking "ok this is where the mate pushes the torp the rest of the way in", but nope, there's a mechanism for that. Also amazing just how much mechanical effort is required, nowadays it's all motor driven and computer controlled!
