Zhang said that the tail nozzle of F22 is not as stealth as that of J-20. Is that nonsense?

Think about it, "kelp wrapped around submarine propeller" can come up with it, or an expert? !

Now that mainstream nuclear submarines are pumping propulsion power, they will certainly not be entangled; Secondly, isn't the offshore "fuck" of nuclear submarines seeking death? !

1 and F-22 use rectangular nozzles to reduce the infrared characteristics of F-22 and increase the stealth effect. When the F-22 is turned off, it is difficult for general radar to find the F-22. Moreover, the infrared characteristics are only tens of kilometers through photoelectric detection.

2. The length of the J-20 magazine is because the domestic missile is large and cannot be smaller. Secondly, the range and operational radius of the J-20 are also relatively short, because the magazine occupies fuel space. If the J-20 increases the magazine again, it means that the fuel load will continue to decrease. Is it stealth to take two auxiliary fuel tanks to war? !

PL 12(SD 10) missile: weight 180 kg, length 3.85 m, missile diameter 203 mm, wingspan 674 mm

AIM 120 missile: weight 157kg, length 3.65m, missile diameter 178mm and wingspan 630 mm.

F-22 is an all-weather aircraft. Why can't we take off? ! There is a video on the Internet, in which the ground crew of the US army directly cleans the F-22 with a faucet. Isn't the F-22 well sealed? !

Professor Zhang's theory is really unacceptable!
