Chengdu J-20 - a Chinese fighter aircraft designed with the intention of reducing the possibility of detection in flight. The first flight of the prototype took place in 2011. Roughly as of ork 2017, several dozen pre-production aircraft have been produced (according to various sources there should be up to 96) which are in the armament of 3 air brigades (1st, 5th and 9th) and two training centers. The aircraft are powered by AL-31F (earlier production aircraft) and WS-10C (current production) engines. However, this is only a temporary solution as a new WS-15 engine has been under development for this aircraft for several years.
