So I was a nuclear operator on a submarine. Our boats are fucking badass, but when we go silent, the plant still has to operate on "natural circulation". Now I don't want to get into that, but suffice to say it means water still has to flow. That flow means a little bit of sound.

Iran has diesel boats. They have to surface every couple days to run their loud as fuck engines to charge batteries.

But once the submerge? Just running on batteries?

They're quieter than us. We would never know where they were. They could sink a carrier in a second.

That being said?

South Dakota, in 9 months. Bet.
