China’s J-20 Stealth Fighter will be put on combat patrols over South China Sea

China’s J-20 stealth fighter has officially entered combat service.

The fighter jet officially entered military service in September, and was put through its combat paces over nine days of drills with less-advanced J-16 and J-10C fighters last month.

The announcement came two days after Beijing announced its Su-35 fighter jets had taken part in a combat patrol over the contested South China Sea.
