The 13th China International Aviation and Aerospace Exhibition, or Airshow China 2021, will be held from Sept 28 to Oct 3 in Zhuhai, south China's Guangdong Province.

Models including the J-20 stealth fighter jets, Y-20 large transport aircraft and Z-20 helicopters will be on display at the show.

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 in 2016.

The Y-20 made its maiden flight in 2013, and debuted at the 10th Airshow China in 2014. The large multi-role transport aircraft joined the air force in July 2016, playing a critical role in China toward developing its long-range delivery capabilities.

The Z-20 is a medium-lift helicopter with double China-made engines. The multifunctional helicopter made its first public appearance during a massive National Day parade on Oct 1, 2019. They can be used in public services, emergency rescue, flight training, air tours and traditional agricultural work.
