My comment;
(a) I can not find the Defense News report, which sometimes blocks non-subscribers from searching for it in its web site--not just from reading it.

(3) China Reinvents The P-3C. Strategy Page, Nov 22, 2011 http://www.strategypage.com/htmw/htnavai/articles/20111122.aspx
("China recently revealed the Y-8GX6, its answer to the American P-3C maritime patrol and anti-submarine aircraft. * * * Until the Y-8GX6 can be seen in action, it's difficult to say how close the two aircraft are in capability")
My comment:
(a) Wikipedia does not talk about Y-8GX6 but does a page for Shaanxi Y-8 运-8, which cited Chinese media (Beijing was silent) as source of the June 3, 2006 crash of a Chinese KJ-2000 in Anhui, killing all 40 persons onboard, whose platform was Y-8.
(b) I can not find a Chinese-language news report, but do know of photos of Y-8GX6 appearing in Chinese web sites this month.
