Acest prototip cu numarul patru inglobeaza modificarile observate prima data la cel de-al treilea prototip J-20.
Fortele Aeriene Chineze ar urma sa aiba o prima escadrila operationala de J-20 pana in anul 2020. The fourth known prototype of the Chengdu Aircraft Corporation (CAC) J-20 fifth-generation fighter made its first flight on the morning of 26 July, according to Chinese aviation websites.
According to online postings by local spotters, the prototype flew for nearly two hours after having undertaken taxi tests since early July. The first hints on military web forums of a fourth J-20 prototype with the tail number ‘2012’ emerged in late June, with clear photos emerging by mid-July.
Images show that ‘2012’ features the refinements first seen in the third prototype, ‘2011’. These include an undernose faceted shape to hold a future electro-optical targeting system, adjusted air intakes to aid engine air flow and clipped tips on the vertical stabilizers.
