While all of those other aircraft have ended up in the field, this one is the future of Chinese tactical aviation.
The J-20 is a purported stealth fifth-generation fighter aircraft.
It's also designed and manufactured by Chinese aircraft magnate Chengdu Aircraft Industry Group.
It first flew in January 2011. The Deputy Commander of the People's Liberation Army Air Force foresees the J-20 to come out in 2017 or 2019. That's similar to the F-35 roll out for the United States.
