We knew about the Chengdu J-20—China’s fifth generation stealth fighter. As it turns out, it’s not the only one. According to China Defense Blog, this is the J-21/J31. It looks even more like the F-22 Raptor than the Chengdu.

China Defense Blog says that this new plane is being developed by tChina’s 601 Aircraft Design Institute/Shenyang Aircraft Corporation. It appears to be the very first flying prototype, serial 001.
As if we didn’t have enough problems with China developing one stealth plane, now they have two in the works. And in a quite advanced state, according to these photos. [CDB and CDB]
