On contrary. F-35 has DSI intakes instead regular on F-22 which are more stealthy.
F-35 has better coating than F-22.
So F-35 frontal RCS should be better.
The US has said OFFICIALLY that the F-22 is "marble-sized" frontal RCS and the F-35 is "golf-ball sized" frontal RCS.
I would rather believe the US officials than someone on the Internet thanks.
Based upon what ? I want to see hard data.
We have are information about the F-35 than we do for the J-31. So unless you have direct access to the Chinese engineers who works on the J-31, anything you say about it is sheer fantasy.
It is hilarious seeing people think that soon to be the richest country in the world also would be incapable of developing the best technology.
