      @The Goldey Family I doubt it, China and Russia save their money. They spend their taxes on benefiting their citizens, rather than the military. They manufacture everything the Americans purchase everyday.

      Wouldn't 'Let's go get smarter together' or 'today' or something of the likes be a bit more appropriate, due to it being an instance of becoming smarter rather than a culmination of instances at once? I feel like 'let's go get smarter every day' for one specific instance of becoming smarter is a bit misplaced and misnomed in comparison, and leads to a moment of awkwardness in my mind; as if it's advice, rather than a welcoming invitation. Maybe it's a solo perception, but here's to hoping this mention of insight can provide some benefit. Cheers, Destin.

    Dräger gas detectors with the annoying tubes still being used today? Takes me back to the best days of my life onboard BB-62 & BB-63. I did six months on the Vincennes after Desert Shield/Storm but the Tico cruiser fleet was never quite the same as sailing on and making history. Surely the Tico was more powerful, better defended than the Iowa class behemoths, and certainly safer in regards to modern design, and safety systems. But even in the 80's and 90's we were brash and bold. My Master Chief on the New Jessey was part of the original commissioning crew in WWII. My Senior Chief on the Missouri Served on her in Korea. Oh my the memories. Thanks!

    Et comment produisent-ils les 78% d'azote impérativement nécessaires à la respiration ? parce qu'on ne respire pas que de l'oxygène... Si l'atmosphère du sous-marin n'était composée que d'oxygène elle serait extrêmement dangereuse. Hautement inflammable, hautement oxydante pour les objets comme pour les humains.. Donc la question est mal posée : ce qu'il fallait demander c'est "comment le sous-marin produit de l'AIR ?"

    This is so old school. It's running on like Windows 87... plus the individual sniffers. Even in the mines we have digital crickets that monitor everything in the atmosphere. At the front of the nation's defence and with every life in the sub directly at risk. Would they not update to 2210 looking computers?

    it is because the sub drains a person soul therefore they don't need oxygen

    I didn't know you can take video cameras and post it only on a nuclear sub. At least when I was active, they filming was never allowed on any nuclear vessel and post in online. I guess time do change...

    Why can’t we use Amin to strip the Co2 from the atmosphere? Global warming solved!

  • Illumin4t

    someone should tell the US navy that there are multi functional sniffers and detetocers out there with more then a single sensor to detec different kind of gas at once. like from Dräger would be maybe usefull on a ship or submarine since space is nothing you should vaste

    I'm assuming that it is fairly difficult to split CO2 via electrolysis. Cause if that was viable you could solve both problems at the same time!

    So either of the Raycon earbuds novels have AAC audio quality? Great video. Loved it. Felt like a feels trip. One thing, you arnt a visual learner, we all are, if we can. It's just that words make it a little difficult to explain things like that.

    This is amazing. Ive read, watched, listened, and question to learn about so many different things in this world. For some reason I fell there is never a good look into how submarines do what they do. I know a lot of that is for security reasons but it still feels ultra secret to me. I paused this video halfway just to comment that for me, it is amazing seeing even what these guys consider mundane, even though important. For many reasons even further than what is discussed here, submarines are a special breed that I find fascinating. Thank you so much for showing a true inside look!

    They DO NOT send all of the hydrogen overboard. lol. What do you think they are cooking with in the galley and for emergency power? I don't understand why they keep trying to keep that a secret. They talked about it openly on season 2 of mail bag. OBVIOUSLY you arent going to waste a perfectly good source of compressed hydrogen and just dump all of it back in the ocean.
