Guess Wikipedia needs to be updated. It is saying that the WS-10 engines are gradually being introduced into the J-15 series. Considering the added reliability question that arises in naval aircraft engines, I thought it was a little odd. As usual, sources were not mentioned but it seems to be just thrown in there that WS-10 ( Naval) is the main thrust producer with 132 KN of thrust. Any chinese sources on the same would be of help for updating the page.
