From the article you cited -I think some people needs to chill for a moment. (Not towards the above article bt people talking about battle with the US in another thread)
It&s actually nothing new we known about this for a while now. It's not about the future but where we stand now.
Initial production models of China’s latest J-20 stealth fighter used the upgraded WS-10B,
Do you think this statement is factually correct?
J-20 is also unable to supercruise, meaning it must use afterburner to reach supersonic speeds. China’s premier air superiority fighter will struggle to keep up with its 5th generation contemporaries until the situation is rectified.
How many 5th generation fighter jets can actively supercruise? How many active production 5th Gen Fighter jets are there in fact? To me, there exists only three - F22, F35 and J20.
Of these only F22 and J20 are designed to be supercruise. Only F22 can do supercruise.
Edit : F22 isn't "active" production. Until and unless they bring back the whole tooling and production line with a token 10-20 Billion investment.
I've been hearing about Ball point pens, China and the equations it tries desperately to make up to point at China's supposed lag with overall tech development for long.
It's is as tiring as hearing Japan is "high tech" while still being reliant on Fax machines and a society that hasn't moved much from the peak of 1980s Bubble Era.
Maybe the author Lewin Day should stick with reporting on Cheap electronics and Home Appliances.
