1. the FWP-14 variants are still in Mass Production
2.further improving FWS-9 reliability and durability.
3.FWS-10H is just qualified.
The only reason I said that the WP-14 engine was abandoned is because tphuang insists so. What ever happened to Kunlun-2 and Kunlun-3?
What are the differences between the WS-10H and WS-10? A new engine is needed to handle sea salt?
Maya, my point in bringing up the J-20 was that if the WS-10 is in mass production and is being used on J-11B and J-11BS, then why install a Russian engine at all?? There would be no reason to stick in AL-31s.
