I got my GDP statement from a Pentagon report? Im talking real GDP, not purchasing power.
Right now, from what I've seen the Yuan class, like so many other Chinese domestic hopefuls, is already outdated, but yes, the export kilo. As I understand it, its hiding and attack capabilities are less advanced. Song should have been cancelled, I highly doubt that the PLAN have worked out the Song's problems? The PLAN will rely on its kilos for all its non-sea denial missions. The Song relies on 1980 era technology, but I have heard that China has been fitting capable foreign sonars on to them.
Misunderstanding on the submarine safety record, but currently the PLAN has the worst record, they lost a submarine last year did they not? I know fires are a regular occurence on PLAN boats. One boat has also been completely disabled at sea recently.
