I stand corrected on my use of ‘loud.’ ‘Quiet’ and ‘loud’ are relative terms. I meant ‘loud’ relative to ours.

But do you really thing anything they have could leave Bandar-e Abbas without us knowing about it? I still say relax , Iran has had these subs over 10 years. This is no problem.

I have to agree that the USN probably has got the prop signatures of these subs long ago.But one also has to understand that D/E subs are usually quieter than N-boats,though their low endurance negates that.One can just look at examples of Dutch & Norwegian subs "sinking" American LA class boats in exercises & most of those boats have pretty much the same characteristics as the Kilo.
