Anyone interested in aviation will want to read this article in The Atlantic. Without a doubt, the Chinese J-31 stealth fighter bears more than a passing resemblance to the American F-22. While espionage is always a possibility, the more reasonable interpretation for the outward similarity of the two aircraft is that the Chinese have studied the contours of the F-22 very closely, and since they are seeking to solve the same problem that the U.S. Air Force is – evade radar – the Chinese designers have applied a ready-made solution to the problem.
It is also likely that the F-22 is still more advanced because of a variety of special coatings and other onboard technologies that can’t be copied so easily.
