China confirms export of eight submarines to Pakistan

[araz]

Most sources say its the S-20
....we don't produce non-magnetic steel - but if the investment is made that can be done

Look at how many countries actually produce nonmagnetic steel. You will realize that it is not just resources. It is resources +time+ R&D.
Secondly what we are buying is not known to the public. S20 are not equipped with AIP. SO IT WILL NOT BE AN S20 as SOURCES suggest. As I have repeatedly said wait till qe know what the specs are and then one can formulate a judgement.
