    @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.

    I was diagnosed with herpes 7 month ago the Doctor told me there was no cure to this infection, l was only given antiviral Herpevex Acyclovir 800mg for 5days, 5times daily, the doctor said it will not kill the virus ,only slowing it a bit from spreading to other part. l was on this for the past 4months no improvement. So there was a day l came across with a testimony from a friend, so l contacted this man on getting his herbal remedy for this infection, which l paid for and received medicine after a week and some days with instruction on how to take medicine attacked. I take medicine for 2weeks before going to the hospital for test...l can show to you now that am herpes free! 😊😊. I fully believed there is a herbal cure for herpes now. l am also using this means to inform you out there to get yours as well!.. contact Dr. Robinson via Email:(

    4.9Torr of C02!!! That is 6.5mbar or roughly 6500ppm C02! The German Norm for indoor office air declares everything about 1600ppm as bad, and even levels below that have been shown to decrease cognitive function. Fresh air is 400ppm. I assume the navy knows about that, just the money for better tech is not invested.

    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!

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 ?"
