The damage that an underwater explosion inflicts on a submarine comes from a primary and a secondary shock wave. The primary shock wave is the initial shock wave of the depth charge, and will cause damage to personnel and equipment inside the submarine if detonated close enough. The secondary shock wave is a result of the cyclical expansion and contraction of the gas bubble and will bend the submarine back and forth and cause catastrophic hull breach, in a way that can be likened to bending a plastic ruler rapidly back and forth until it snaps
Underwater weapons like depth charges dont explode on impact, they are set to explode at a certain depth. The instant water displacement caused by the explosion causes a very powerful shock wave in the water that hits the sub like a giant hammer. Good video!
I love to see how delighted you are at actions that we Americans have done. We, as a people have always gone our own way, with our own view of right and wrong. Sometimes, we have seriously got it wrong, and we've learned from those mistakes, and tried to set them right. Early on, we chose to 'try to do the right thing' and we've given aid and much to the annoyance of many Americans, each time we've gone to war, and won, we've sent in aide afterwards to the country that was destroyed, for rebuilding their country. We have done this so often, that there was a book written about it called "The Mouse that Roared" about a tiny country that really needed help, so they declared war on America and lost without a battle, depending on the aid to get their country up and working.
Fun fact about the U-505 and its crew; the racks (beds) were only made to accomodate a sailor of roughly 5'8" in height (submarines like tanks were crewed by shorter personnel due to space requirements) and the tallest crew member was 6'3" in height.
Depth charges are dropped or rolled into the water from ships or aircraft and detonate at a predetermined depth. The detonation creates a hydraulic shock that damages the submarine's hull and instruments, forcing it to the surface
I went to Chicago this past Spring specifically to see this submarine. I've never had an interest in going to Chicago before. I've been to several of our large American cities & to me, Chicago would be just another one. (Changed my mind after the visit. A lot to do and all rather easy to get to.) I've been interested in WWII all my life and after I saw TFE's video on U-505 I knew I had to see it. You can get a tour inside the sub and all the displays and info outside the sub is fascinating.
The effects of an explosion above the water can be lessened by going beneath the surface because much of the shockwave of the explosion is absorbed by the water...water doesn't compress like air does, so it takes a considerably larger amount of force to displace the same volume of water as air. You'll still feel (and hear) the explosion, it'll just be much weaker than if you were above the surface with the explosion. Underwater explosions, like depth charges, work more in a 2-stage system...again, water doesn't compress easily like air. The initial explosion creates a shockwave that pushes the water away from the center of the explosion, leaving a void/vacuum there. That initial shockwave hits and batters the sub...not a huge deal, subs are designed to handle pressure coming from one direction fairly well, but it can toss the people and equipment around and result in injuries/deaths and damaged equipment if the charge was close enough when it went off. The "second stage" happens when the water rushes back in to fill the void/vacuum left by the "first stage" (the initial explosion), this creates a secondary shockwave that hits the sub from the opposite direction, so you're basically bending the metal of the hull back and forth rapidly. Subs, and metal in general, doesn't withstand that particularly well, especially when it's happening fast. If you've got several depth charges going off one right after another, that constant flexing can (and generally will) break seams between plates, causing a breach that forces the sub to surface or just outright implodes it like an empty aluminum can (depending on how deep the sub is).
US Navy Veteran. The extremely hard, we do immediately. The impossible may take a minute. Example: USS Samuel B Roberts, mine strike, Persian Gulf, Operation Prating Mantis. If you really want to see how America rocks at sea, check out the original "Sammy B" from WW2. It was called "The Destroyer Escort that fought like a Battleship". Battle of Leyte Gulf, 25 Oct, 1944.
I want to say l enjoy your channel. I assume you are immigrants, you seem to be proud of America and happy to be here. You're both very pleasant people and if l ever met you, I'd immediately consider you my friends. I wish you continued success.
Its my day off any yall drop some fat electrician reaction i feel blessed. Thanks guys 😊
Ya we did that.! 😎🤟✌️

I’m from Chicago and went through a couple of tours through that U boat!! 😅
I went there as a kid back in the 80's and I still have the cheap plastic souvenir submarine you could get made in the machine for a couple bucks.
I toured this sub in the museum in Chicago. Super cool!

Almost. The hedgehog was made to only go off on impact. This made it easier to keep track of the sub

Happy for your marriage, waiting to see the kids. Love y'all
I've been through it. When I was young, I didn't realize the story. As I got older, now I find it really cool.
Believe it or not, underwater explosions actually amplify the concussive force of an explosive. That's something I was taught in the navy
Water doesnt compress like air so more buck for the bang.
Hey Veli and Glory! I hope I got your name right this time! I loved your reaction to this story!
Loving the Fat Electrician reactions😂😂😂😂
Love your channel Florida USA here!

If you want to learn more about U Boats, there is a very old movie called, "Das Boat" about a U boat crew during WW11

They moved to Chicago thru the St. Lawrence Seaway

15:38 no way you believed that lmao
its not explosion that damages the ship. its the shock wave of air created underwater from the explosion that does most of the damage.
You can fold a metal door with a bag of water.
I just subscribed after catching a few of your reactions. You can’t go wrong with the fat electrician. North Carolina USA.

Please react to Joe Medicine Crow. It's one of his best videos.

Not that America is great, I love seeing how you interpret Americans
Please show this Fat Electrician Video: The Last War Chief - Joe Medicine Crow. (This is Another True WW2 video).
I can't understand a word this girl is saying. It'd prolly help if I could hear her.
