I suspect you won't ever get a number you could take to the bank, MM. Years ago I had a former Navy nuke sub driver as a student worker at NU Law, and while he'd share wee snippets and anecdotes, was tight-lipped, as he well should've been. One I recall well when I asked him about the rough speed and maneuverability of the boat went like this: 'they're a lot more agile, faster and will run deeper than you'd ever believe, probably, but that stuff is classified. I will say though that I used to love when we drilled on emergency blows. I could make that bitch sit up and bark for me!"
I do know the speed and max depth on some classes of subs and I know why some are so quiet but will die with that info.
