Lets also hope that Sweeden isn't going goin to just sell these things to just any Tom, Dick, or Muhammad.
For Sweden to sell it,they'd need a go-ahead of sorts from the Germans as their sub-builder has been brought by a German firm.Besides,there are other equally capable or better AIP options including French & Russian ones.The first export submarine to feature an AIP is a Pakistani vessel which uses the French "MESMA" system.
The Swedes are very careful who they export arms to. And they don't sell their high-end stuff.
