At Waddo show last weekend, I spoke to the Saab reps by their MPA demo and they said with the increase of diesel subs in 'questionable' hands, it makes life very interesting for the ASW club. I was quite surprised to find out that the modern diesel subs are harder to find/track then the nuclear ones, from the Saab lot. I personally thought it was easier to track diesel as opposed to the ultra quiet nuclear lot.
