The 70-feet Chengdu J-20 seems to use Russian 32,000-pound thrust 117S engines with vectoring abilities. It looks similar to the F-22 Raptor, but larger. Probably that means lower agility, but more weapons and fuel. In any case, copy or no copy, the Chinese keep building up their arsenal. [Aviation Week]
