While accurate information about the J-20 is scarce, there are indications that the Chinese aircraft is equipped with a phased array radar, a robust electronic warfare systems and an electro-optical/infrared sensor that is similar in concept to the F-35’s systems. However, while it is possible that the Chinese aircraft might have decent sensors—Air Force officials have suggested that the J-20 lacks the “sensor fusion” and networking to be as effective as the F-22 or F-35.
