In 2019, China will start deploy J-20B stealth fighters with a new Xian WS-15 jet engine. This engine could finally bring China to about the engine performance level of the US PW-119 engine that were installed over 20 years ago in the F22.
The US has jet engines programs to improve and the power and fuel efficiency of engines compared to those used in the F22.
China is continuing to refine the stealth and various component and systems in their J-20 and J-31 stealth fighters.
China is also continuing to upgrade and improve stealth technology and engines in large stealth drones.
China could soon reveal a stealth bomber which might be comparable to the US B2 stealth bomber.
China’s Air Force is well funded and is clearly surpassing Russia’s air force and catching up to US military technology on the whole range of systems.
