YouTube: Carrier-borne JL-9 flight trainer

This video was part of a series by CCTV to commemorate the 90th anniversary of the Communist Party of China (CPC). This one looks at test pilots of PLAAF who are all members of the CPC. Fast forward to the 4:29 of the video and you’ll see the carrier-borne version of the JL-9. The aircraft seems to have conformal fuel tanks added.
