While digging around for that new Sweetman article found this.
Seems like they're still going along with the idea that the J-20 is a big tanker killer.
EDIT: And Sweetman seems to have a startling lack of knowledge on China's engine programs.
EDIT2: I'm going to wait a few days for someone with an Aviation Week subscription to post the article. If no one does it I'll take one for the team and purchase a subscription. BUT if anyone's in the Bay Area you're all treating me to an expensive dinner.
