China's J-20 stealth fighters have started to patrol the East and South China Seas as part of routine training missions, state-owned media reported.

According to the Global Times newspaper, the announcement was made by Ren Yukun, head of the discipline inspection and supervision team and a member of the leading party group at the state-owned Aviation Industry Corporation of China (AVIC).

In a press conference on 12 April, Yukun reportedly said that it has become a training routine for Chengdu J-20s to fly “combat patrols” in the East China Sea and “alert patrols” in the South China Sea.

He added that these patrols are being undertaken after the J-20 switched to using “domestically developed engines”.

The aircraft were originally powered by Russian-made Saturn AL-31FN-series engines. Janes previously reported that the Saturns are starting to be replaced by indigenously developed Shenyang-Liming WS10C turbofan engines from at least September 2019. The Chinese engine is said to offer superior thrust in comparison with the Saturns.
