Okay guys, I was just doing some research on the web about Scorpene and AIP and I came across some interesting info on Wikipedia. It seemed that Pakistan was looking at Marlin class subs as replacements and was actually seriously considering them. I looked around a little bit on Google and I found a couple of websites(All Pakistan based though) that corroborated what I read. The Marlin class seems to be the next generation of Diesel-Electric submarines that are going to be built. Now, I am guessing that India put its foot down on the deal or something? If someone could find some info on this, it would be appreciated.
