During the training, the J-20 jets first took control of the airspace while the J-16 and J-10c jets conducted long-range precision strikes against ground targets.

He Xing, an air force pilot, noted that they aim to give full play to the strengths of different fighter jets throughout the training.

“The training will help the air force better fulfill its sacred duty of safeguarding China’s sovereignty, security and territorial integrity,” said Shen Jinke, spokesman for the Chinese People’s Liberation Army Air Force.
