BEIJING, Oct. 28 -- China's domestic-built J-20 stealth fighter will make its public debut at an air show in Zhuhai City next week, with air-force pilots flying the new-generation warcraft, a military spokesperson said Friday.

The development of the J-20 is progressing as scheduled, and it is expected to further boost the fighting capacity of the Chinese air force, said Shen Jinke, spokesperson of the People's Liberation ArmyAir Force, at a press conference.

The J-20 made its maiden flight in 2011.

Shen said the fighter jet will help the air force better fulfill the mission of "safeguarding national sovereignty, security and territorial integrity."

According to Shen, though it will not fly, the domestic-built Y-20 heavy transport aircraft will also be displayed at the 11th China International Aviation and Aerospace Exhibition, which runs from November 1 to 6, in Zhuhai, Guangdong Province.

The Y-20, a versatile plane with a maximum takeoff weight of about 200 tonnes, is designed for carrying cargo and personnel over long distances in "complicated meteorological conditions." It officially entered military service in July this year.

Other aircraft such as the H-6K bomber, the J-10B fighter jet and the KJ-500 that is China's early warning and control aircraft will be showcased at the exhibition.
