The J-20 is China's fourth-generation medium and long-range fighter jet. It made its maiden flight in 2011 and was first shown to the public at the 11th Airshow China in Zhuhai, Guangdong Province, in November 2016.
The fighters made their parade debut when the PLA marked its 90th anniversary in July 2017 at Zhurihe military training base in Inner Mongolia Autonomous Region.
