Makes no sense does it?
"Any fleet anchorage or chokepoint or convoy guarded by a handful of Merlins or equivalent helicopters is pretty much safe from attack by AIP submarines. AIP boats would be highly effective against countries without modern ASW helicopters, but not against first- or second-ranking powers.
Third- and fourth-rank militaries usually don't have very good seagoing radar/infrared coverage either, though. So in fact a normal sub without AIP would probably do fine against them: or even a still-simpler surface ship."
If that was really true there wouldn't have been any need for the US to borrow one of our Gotland class subs for training of over a year right? Let's face it, you're a bit jealous that you don't have one yourself.
