I wonder how accurate these things are. Russians make the same claims about the RCS reduction techniques on Su-35 on Su-30MKI and such. I think the only thing I get out of this is that there are some RCS reduction been applied.Applying RAM in various places. And of course we're not sure that's conclusive, unless we can sneak away a J-11B and put it on a RCS test range. But it's certainly a number we should keep in mind.
