but didn’t Soviet attack subs wait outside the home ports for the SSBNs to try to stay on their tail, and they never managed to?

I wouldn’t be surprised.

But I know one of the most classified parts of a sub, is what the propeller looks like. Because then you could determine what it sounds like.

Knowing one was at X location at Y time is dangerous because then recordings can be compared to other periods and if anything stands out…

Then you can search for that.

It’s just a whole lot of risk in area we go thru ridiculous pains to minimize any risk, for no legit payoff.

There’s just no logic behind this move or rationalization of it.
