The J-10 (歼十, Jian-10) is a multi-role fighter aircraft was designed and produced by the People's Republic of China's Chengdu Aircraft Industry Corporation (CAC) for the People's Liberation Army Air Force (PLAAF). It is designed to be equally useful in both the fighter and light bomber roles, and is optimized for all-weather day/night missions.

The delta-wing, a triangular wing platform, offers two important aerodynamic qualities. First, the swept leading edge of a delta-wing stays ahead of the shock wave generated by the nose of the aircraft during supersonic flight, making the delta-wing a very efficient aerodynamic wing shape for supersonic flight. And secondly, the leading edge of delta-wing also generates a massive vortex that attaches itself to the upper surface of the wing during high angle-of-attack (AOA) maneuvers resulting in very high stall points. Additionally, the delta-wing offers increased survivability by having increased structural and airflow stability.
