It is China's third-generation supersonic fighter and made its debut when the PLA marked its 90th anniversary in July 2017 at Zhurihe military training base in Inner Mongolia Autonomous Region. Equipped with an advanced avionics system and various airborne weapons, the domestically-developed fighter has airstrike capabilities within medium and close range and is capable of precisely striking land and maritime targets.
