- Submarine torpedoes are highly complex weapons, even in WWII. Air was used to blow the steel fish down the tube, but how did the steam turbine or electric motor get switched on to propel the torpedo on its way to the target? Cod President Paul Farace reveals the secret in this video from USS Cod Submarine Memorial!

Paul, Love the videos you are doing. Please go over the individual gyro and aiming controls that programmed the torpedo. I have never seen this type of detail on any other channel.
For examples like this in the future a laser pointer may be helpful :-)
You should go through the procedure for firing the torpedo, load, close,set input data, flood , open doors, and shoot and how its done
I think you just did that for me!😊
No wonder you never noticed that little tab for starting the engine/motor. It's like the light inside a refrigerator. You can't see what's going on when the door is closed unless the door is actually closed.
very good video respectfully suggest using a laser pointer to point out items
Where i say the "little boat propeller" that sets the speed... I misspoke ... it's the depth setting spindle! 😮
Love the short informative videos, hope to see more in the future. Keep up the great work
I've been a diesel boat afficionado for 45 years. I've learned amazing details from your videos. Keep up the great work!
About 20 years longer for me. Did get a tour when the New London sub school gave them, of the boats they used in training. (WWII era diesel boats somewhat upgraded). That was a long time ago.
I do remember seeing some piece of equipment with bubbles and the tour guide could not tell what it was for. Must have been a non-qual puke, because a qualified submariner would have known what everything was. Or maybe it was secret.
I've been working my way through these videos on Cod, and I gotta say every single one is fascinating. Thank you for this excellent series.
Paul, I remember the tour you and Tom Street gave my wife and I back in 2019 just before you guys took the COD for overhaul in the Toledo ship yard! I gave a talk to my Shipmates at our USS CAPITAINE reunion on the USS COD tour for which we will always be grateful! The TLC your crew members give the COD is remarkable, the Boat is so well preserved I felt like the crew was off on liberty and would soon return before getting underway!! Thanks again Sailors, Tom Morris TM 2 (SS)
I always look forward to your informative videos on the operations of a fleet boat. Thank you and fair seas.
My dad was a submariner and I still learn from these videos. Thanks
i remember visitors being in awe not only at this room, but at that cut-out. So many were worried they were still active, however, with reassurance, they left knowing they weren't "active" Great video, as are all of them😃
Great video Paul!! I never new how the torpedoes were activated. Looking forward to seeing the videos on how the gyros were adjusted while the torpedoes were in the tubes. Is there anyway to do a video on how the TDC works?! Great stuff! Thank you!!
These videos are very informative! I grew up reading about WWII sub ops, especially the US boats in the Pacific, but a vast amount of detail was left out.
Please don't fire Evan out of the tube, he's a decent cameraman.
But is he the right caliber.
I always wondered...
I can't wait to come and the restored Cod next time I am in Cleveland!
I once worked at Gould Ocean Systems that made the MK-48.
Another interesting video Paul, thanks. And thanks for pointing out that the electric fish had motors and the steam ones used engines. People call engines "motors" all the time and it drives me a little batty.
Same. I've always defined an engine as something that uses heat expansion to generate rotational energy, steam engine, jet engine, piston engine etc. Motor is something that uses an external source of power and doesn't involve heat expansion, electric motor, hydraulic motor, air motor, etc. Then you have motorcycles, outboard motors, motorboats, General Motors and Detroit as motor city, just to add confusion.
By definition, there is no real difference. "Motor" and "engine" can be used interchangeably in these cases.
Colloquially we use motor for electric, engine for ICE, but that is not by definition.
Torpedoes! Sounds like a blast 😆
I've been aboard Cod a number of times! My parents are from the Cleveland area so I had the opportunity to visit whenever we were with my grandparents. I would really like to come back sometime and get a U.S.S. Cod patch.
Fascinating technology. Thanks, Paul!
This is a great one. Something I’ve wondered about for a moment here and there but never dug into.
I assume a surface launched torpedo would have the same setup?
If you crack that noggin on another lump of metal, I will strongly recommend a nerf helmet😉
Just kidding Paul, keep up the good videos. And watch that noggin!
Loving the new videos, keep em coming!
What was to stop the switch from being tripped accidently during handling? That would be catastrophic.
Torpedoes were charged with air at sine point before being fired... and other things. I believe there may have been a protective cover as well.
@@paulfarace9595 Thank-you. That is great information. Cheers.
I have heard of Hot Runs - where a torpedo that hasn't been loaded into the tube starts running. I hope you'll do a video on these very dangerous occurrences. TY.
Hot runs occurred in the tube as well!
Very informative, Thank you.👍👍
Thank you for these videos...love them!
Thank You :)
Great presentation!
Very Intresting
New info!!
Keep it up🎉
Very interesting, thanks👍🇦🇺
Neat, thanks for sharing!
My Dad went out of the tube at 50' for UDT training. Nuts.
What a great presentation. I always wondered how a torpedo was launched/programmed/activated...and it all makes sense. Thanks!
Cool video! Conn, Dry run in #1 torpedo tube! What do I do now?
The governor will shut it down, so you need to change into dress uniform for your Captain's Mast.
Very cool
Subbed, Liked and ready to view, Sir! ;)
Don't call him sir, he works for a living, and I bet he knows who his parents are!
@@grizwoldphantasia5005 what bilge are you spilling here?
Cool!
The Mark 14 - Had Firing Pin Problems...The Navy - Refused to Listen and Many Were Duds...Until Sub Crews Solved the Problems...
The Mark 14 had everything problems.
Sub crew members didn't solve the problem (that was a movie plot point) ... engineers and folks ashore studied the problems and took input from the crews (deep running and bad magnetic detonators were also issues) ...
The Mk 14 couldn't even be used to any real meaningful effect by the Torpedo planes of the time. Lots of bounce-offs.
That's very cool.
Does the switch on the torpedo have some sort of safety mechanism to prevent it from accidentally being tripped when it's sitting outside of the tube?
Nope
@@paulfarace9595 Any kind of a cap then? I mean, it was that easy for a torpedo' to start running if somebody bumped the switch while loading the torpedo into the sub or into the tube?
@@chrisfreemesser5707 I guess they would not be fueled and pressurized when loading into the sub?
my guess is the switch actually take good deal of force and most likely has a safety pin.@@chrisfreemesser5707
Would like to see a video on how the torpedos gyro and depth were set in the tube from the conning tower or in the torpedo room. Where was the physical connection?
how long, after the switch is flipped, does it take to make full steam?
Very cool video!! 😊 what stopped the crew from accident;y hitting that “light switch” to start the torpedo, when it was sitting in storage inside the ship? Like were there covers or safety pins or something from stopping the trigger from turning on the engine when it wasn’t supposed to turn on? 🤔
Excellent video, thank you.
Do you have any diagrams on the actual outer door mechanism and how that keeps water out while the inner tube door is opened?
Its closed when the breech door is open ... an interlock prevents them both from being open simultaneously.
In those films there was always that bit where they shout out: FIRE...FIRe....FIre...Fire....fire....As the instruction was passed down the boat. So did that really happen?
No! The order to fire was generated in the conning tower or the bridge by the captain and transferred to the system hardware by the firing button. But simultaneously the firing command was echoed to the torpedo room via the phone talker so that the tube could be fired mechanically on the event the electric firing command was faulty. That's two places in the boat. Also in many shooting cases once the target ship was designated the TDC would constantly update the firing data to the torpedoes as the sub maneuvered. This allowed captains to choose the ideal time to begin firing based on other parameters. Achiving a firing solution on the TDC wasn't necessarily the time when firing began.
It seems to me that the torpedoes have to be loaded into the tubes in a very specific way to be tripped by those protuberances. How do they make sure the torpedoes are loaded at the right "angle?"
How accurate to that angle must they be stored?
Yes they do and there is a guide cleatvthat fits into a channel or groove at 12 O'clock thatvruns down the tube .
@@paulfarace9595 As was briefly mentioned in the video, but easy to have missed.
@@paulfarace9595 I did miss that! But that raised the question: these things are heavy and as I re call had to be manhandled into position. How did they rotate the torpedo to make sure the cleat fit the channel?
I thought you were leaning on a stove and this was a cooking show! Firing a fish?!?!? What the hell???
can we see where they store the torpedo juice?
Coming in a future episode 😂❤

How much air pressure does it take to fire the fish.

If you want to see how a modern sub fires its torpedo's, go to th-cam.com/video/UYEyhB0AGlw/w-d-xo.html. In Smarter Every Day, Destin crawls down a torpedo tube, something done every month, and then explains how the torpedo is fired. Apparently, the procedure is different on modern Nuc subs than the old diesels. On the modern subs, the torpedo is launched using a slug of water from the sub, while the old diesels used compressed air. My guess is that because Nuc subs spend most of their time under water, air is something that they don't want to just push out into the water. The diesels, on the other hand, spent most of their time on the surface, so air was easily replaced, usually. The times when they couldn't surface, they wouldn't be launching a torpedo anyways.
How to fire a fish: can it? 😁
i was so disappointed that viewing could not have been arranged when she was in erie.
So were we! But you don't have any big tug boats that could handle us!😢
How do you flood down and equalize the tubes to sea pressure for firing? How do you open the outer doors? How do you drain the tube afterwards? What tanks are involved in these processes? Were you a submariner?
Several videos on TH-cam covering your questions. Just search.
All subjects for future programming. We're in this for the long run!
Was the alcohol in the torpedo drinkable? I heard a MYTH about Sailors drinking the Alcohol.
😎
So roomy compared to the USS Razorback that's in Little Rock!
In the cold war they added gear more than removed it. So over time the interior got more cramped.
Why would you have a fish in your employ? Just give 2 weeks worth of food as severance.
If it was pre 1943 the damn thing wouldn't have exploded.
A lot didn't explode in 1944!
Too many didn't work in 1944!😢
Not the dreaded Mk14 torpedo that was horrifically bad ? You should do a video about how incompetent BuOrd was with that, naming names.
Actually I am not ready to lynch BuOrd ... every country's navy had trouble with their fish. Problems with testing too. The real crime was the refusal of Christie to consider the possibility that his magnetic detonator was flawed.
So how does the Museum handle all of those Mk. 14 duds the Bureau of Ordnance gave to the U.S. Navy?
🤣👍
You should just make life unpleasant for the fish so that it quits. If you fire the fish you might have to pay it unemployment.
if all goes well when you fire them they run away from you and commit suic!de
