The aircraft bear a two-tone paint scheme with low-visibility markings and additional outlines that emphasize their main and two side weapon bays. For the display, the fighters were fitted with Luneburg lenses aimed to disturb measurement of their actual radar cross-sections. The J-20 debuted at Airshow China two years ago, when two low-rate initial production aircraft performed a flyby.

The Chengdu J-10B 1034, a prototype owned by Avic, is used for the first Chinese test of thrust vector control (TVC). It performed its first flight fitted with TVC on Dec. 25, 2017.

The J-10B testbed delivered impressive performance over Zhuhai. The Chinese nozzle is 3D—that is, deflecting up/down and left/right. The Russian twin-engine Sukhoi Su-35 fighters operated by China have 2D (up/down) nozzles, and the 3D effect is obtained by proper V-like arrangement of two 2D nozzles. It is known that Russia offers a Salyut AL-31FN-Series 4 turbofan fitted with a 3D nozzle for the J-10 fighters; however, for obvious reasons, China prefers indigenous development.

The Xian XAC Y-20A heavy transport aircraft emphasized its short-takeoff-and-landing (STOL) features, demonstrating a flyby with high-lift wing devices deployed and performing a very short landing with thrust reversers.

At least seven Y-20As are in service with the Chinese air force; deliveries started in June 2016. Aircraft No. 11056, which flew at the air show, is described as the sixth operational aircraft; No. 11057 was on the static display.

The three most engaging aircraft flying at Airshow China 2018 were the J-20 stealth fighter, J-10B testbed with thrust vectoring and Y-20A heavy lifter.
