Y las ruedas. También le han copiado lo de ponerle ruedas...

Compara coches de hoy en día y verás que también tienen semejanzas unos con otros, o coches de los '80 por ejemplo, lo mismo, y no son copias unos de otros, es la evolución del diseño y la tecnología, y así en casi todo, teléfonos, vestuario... Decir que un J-20 es una copia del F-35 es como decir que un Mustang es una copia de un Spitfire porque los dos tienen la hélice adelante, ala baja y ruedecilla atrás.
Además, cuando los chinos copian, copian de verdad, sin complejos, no haciendo cosas algo parecidas.

TAIPEI — Two years after his arrest in Canada, Su Bin, a Chinese citizen you ran Lode-Technology, has pled guilty in a California federal court to carrying out a series of cyber espionage thefts of U.S. military secrets that included the C-17 Globemaster, and Lockheed F-35 and F-22 stealth fighters.

Su was arrested June 28, 2014, in Canada and waved extradition to the U.S. in February 2016.

Details of other aircraft and U.S. companies are sketchy. Su is alleged to have obtained F-35 test plans and "blueprints" that would "allow us [China] to catch up rapidly with U.S. levels ... [and] stand easily on the giant's shoulders," according to Su's emails.

¿Este de qué se supone que es copia, C-141, C-17, A400M, Il-76?

Por cierto, entonces el F-35B es una copia descarada del Yak-141.

Luckily for Yakovlev, America’s favorite plucky multi-billion dollar defense contractor raced in to save the day. As the Iron Curtain receded across Europe, defense giant Lockheed Martin started to pour money into Yak-141 program in order to glean some sweet, sweet former Soviet engineering secrets. The two companies allegedly signed an agreement in 1991 (but not revealed until 1995) that outlined funding for additional Yak-141 prototypes, including a plan to fly the remaining operational prototype the Farnborough Airshow in September 1992.

While Lockheed most likely had zero intention of helping produce the Yak-141 for export; it would make more sense that the entire contract was a cover for procuring testing data on the Yak-141 program, including most importantly any VTOL data obtained through years of testing and development. And Lockheed wasn’t the only American organization looking to learn from the Soviet-era VTOL program.

In June 1994, Lockheed revealed that it had entered into a collaborative relationship with Yakovlev on their bid for the Joint Advanced Strike Technology competition, consisting of the purchase of design data from the Russian company; according to Jane's All the World's Aircraft 2000–2001 this was data from the cancelled Yak-141 program which employed a similar vertical takeoff/landing propulsion system.
