Lets clear the Question Detalis
Once upon a time, I heard something like "China hacked X country and stole aircraft designs" and rest of the news were about an newer Chinese jet
Now, It looks somewhat like the F-22 Raptor
Now the last section (Video under here) was put as a joke
But admit it , even though it looks like an joke, It looks extremely the same ! (It also looks like J10)

    $\begingroup$ Your title takes for granted that it was "stolen", while the body of the question does not. Which of the two? $\endgroup$ – Federico Dec 5 '17 at 12:23

    $\begingroup$ Any answer to this question can only be speculation. China will never admit stealing plans and proving they did is virtually impossible. $\endgroup$ – Notts90 is off to codidact.org Dec 20 '17 at 13:46

Where was the J-20 design stolen from?

There are various unsubstantiated reports circulating which link the J-20 design to

A criminal complaint filed in 2014 and subsequent indictments filed in Los Angeles charged Su, a China-based businessman in the aviation and aerospace fields, for his role in the criminal conspiracy to steal military technical data, including data relating to the C-17 strategic transport aircraft and certain fighter jets produced for the U.S. military.

But overall, the suggestion that the J-20 airframe design was stolen is not well supported.

One theory states, that the design was taken from a videogame? Could that be true?


  • $\begingroup$ That "Video game part" wasnt there, someone edited without knowing the fact that, that was an "joke" $\endgroup$ – Delta Oscar Uniform Dec 5 '17 at 19:19

When posting such questions you might want to give more context; who is everyone and where are they saying that it has been copied.

The J-20 is based on an earlier project called J-XX, dating back to the 1990s. It is very doubtful that it has been copied from a computer game, as the design process of a military aircraft cares little about the visual looks and more about the aerodynamics and performance. A computer game on the other hand cares nothing about these aspects, and only about how it looks.
