I think maybe I'm underestimating the complexity of the technology. It seems like it shouldn't be that hard, I'm kinda imagining something like a weather station or a seismometer. But one thing you've helped me realize is that, at minimum, that comparison fails to account for the complexities of operating in a marine environment.
And the undersea cables operative to passive sonar? Or are they more to prevent the stations from being identified and their signals intercepted, as would be the case of if it were over radio?

Maybe I'm just naive to submarine stuff, I know very little, but this doesn't seem that weird to me. If everyone died onboard from, say, a fire, the vessel might keep steaming for a long time. Presumably, the CIA has a good idea if that's the case, for all the good that does us.
