Submarines Are WAY Scarier Than You Think...Here's Why

It would be so sick if you made a video about how underwater cables came to be and how they work nowadays.

As a former submariner, I can neither confirm nor deny that I enjoyed this video.

My son retired from the SECRET SILENT SERVICE after 20 years. He gave me a tour of his sub and the tight quarters the submariner’s live and operate in daily. It takes a different kind of person to be underwater in a metal tube for days and months - a really brave kind of man.

Wanna hear something that utterly ups the terrifying nature of nuclear submarines? I was cleaning out my ex’s car some years ago, and found some documents from her ex, who had served on an ICBM submarine in the US navy. One mentioned a dishonorable discharge from his military service. I was curious as to how he had managed to get a dishonorable discharge, so i asked. Her answer changed the way i view the world forever. Homeboy had been selling his fellow sailors LSD, while on active duty. I mean, i thought that scene from Apocalypse Now was wild, but hearing this story was mind blowing. People with their fingers on the doomsday button, tripping balls on acid in a compressed metal tube with no windows. True story.

In a world of tiktoks and YouTube shorts it's always amazing that Johnny is able to consistently make these 30 minute videos and still hold our attention Amazing editing!!

As a current submariner, it's appriciated that so many people are starting to realize we exist. Quality video

Was open-water kayaking off the Olympic Peninsula, Washington State, USA when a very large sub slipped by underneath me. Saw a faint dark shadow and felt a "swell" as it passed with just the slightest mechanical sound. Very strange experience.

I just love how YouTube randomly recommended this video to me and when I went to the channel's videos, I saw that he uploaded a video about the underwater cables just 2 weeks ago. Love it.

The coolest thing about submarines that i know about is that the design of each propeller is confidential as it can be used to isolate their sound profile, which is why you will see subs all the time in dry dock and a tarp over the tail

I find it absolutely insane that the main factor that keeps humanity from annihilating itself is different groups of humans divided by arbitrary borders holding a knife at each others throat at all times.

I lived that life for ten years and its still entertaining to hear about it on your channel. I would really love your take on Admiral Rickover. He was a legend amongst submarine nukes. Especially because he wasn't just given the go ahead to but nuclear plants on submarines. It led to the abomination of the uss enterprise with it 8 submarine nuclear reactors. The only of its kind out of his defiance to produce a nuclear carrier instead of a submarine. It was said that the enterprise was supposed to be so absurdly expensive that it would never be built. Of course it was built anyway. Rickover also obtained funds for his reactor prototypes via "creative ways" when his research projects were denied.

It's incredible we getting this top tier journalism for free. You and your amazing team have my full support, thanks for the great vid.

Yes Johnny! I would be more than happy for you to 'dive' down the sub spying rabbit hole. I mean I'm happy to watch more or less all of the stuff you make for us anyway, but, and I'm sure I'm not just speaking for myself, I think a lot of us must love you not just for your detail but your unusual yet fascinating choice of subjects. You make me feel like I'm learning about stuff that's dangerous to know lol.

What I love about Johnny Harris' videos is that they always feel like a friend that grabs me by the forearms, wide eyed, and whisperly shouts "you won't believe what I've just read!" Just makes me forget how many hours of research, scripting, and editing went into making these awesome videos.

The people who invented subs are genius The people who built them are skilled The people who navigate them are cunning The people who they target are....toast. You could do a whole video on each group of people because there are a lot of Rabbit holes involved in every aspect. Well done on explaining the submarine I learned alot from your videos. Thanks 👍

The video is awesome, but there is something that I need to point out in the beginning of the clip - this is not a rocket, it is a missile. -> The rocket's motion is based mostly on the natural laws of physics - aerodynamics, ballistics, direction of launch, gravitational forces. It is in many cases considered an artillery projectile with a thrust generator in its tail. Once launched, it cannot be guided, so it usually hits the target it's aimed at, as long as this target is reached before the fuel gets depleted. -> The missile is intended for pinpoint precision. You need to make sure the missile hits not just A target, but THE target. Therefore it has several guidance systems and sensors such as GPS, INS, RADAR, heat or radiation-seeking etc. It also has a rocket engine, but it is used only in the initial stage of the weapon. And, since they don't need to be aimed, missiles are almost always launched vertically. -> Here is where the confusion may come. Any vessel which is intended to carry out people or equipment in space, is called a "rocket", and it used to be such for a long time - the rocket sends the package in space and falls back to Earth as, technically, a piece of metal junk. However, the SpaceX Falcon rockets are called rockets, but are actually missiles, since they can be guided back to the launch bay and used again and again.

As a current submariner this is probably one of the most informative and entertaining submarine videos on YouTube. A lot of in depth knowledge

I cannot express how I am grateful to the whole team behind these scenes. Kudos to you guys.

Fun fact about MIRVs is that not all 12 warheads will be thermonuclear bombs. I don't know the ratio, but there will usually be several dummy warheads in the mix. And while the Mk. 7 blast yield is currently unknown, some (NATO) warheads aren't even "that terrible." The tactical W76 (tho these subs normally only carry one of these) is between 5-7kt and Mk. 4's are from 90-100kt. There is the Mk. 5 with its 475kt but regulations state that a maximum of 8 of these warheads can be fit into a single Reentry Vehicle (so 8 live; 4 dummy). For reference: Fat Man - 21kt, Fission bomb (dropped on Nagasaki) Little Boy - 15kt, Fission bomb (dropped on Hiroshima) W56 -1200kt, Thermonuclear warhead (Minuteman II ICBM)

You’ve earned a sub, no pun intended lol, great editing and awesome commentary. Entertaining and informative the entire time. Fantastic video very well done. 👏 👏 👏
