This Is China's Secret Stealth Strike FighterS

Unlike their Shenyang J-15 Flying Shark—a copy of the Russian Sukhoi Su-33—the new Chengdu J-20 stealth fighter seems to be a copy of the American stealth fighters, with some lambda wings attached. It was secret. Not anymore.

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]
