J-20 with WS15 engine first flight! This is the Chinese answer to the U.S. F-22 F119 turbofan engine

The latest Chinese fighter jet turbofan engine, the WS-15, has flown on the Chinese J-20 stealth fighter for the first time. A new video shows that the J-20 with two new indigenously developed WS-15 engines took off from factory airfield and completed first flight. The WS-15 is similar to the F119 engine in the F-22 fighter. The J-20 fleet had been using Russian AL-31 and Chinese WS-10 engines. Comparing with the older engines, the WS-15 has zigzag exhaust nozzle edges. The WS-15 reportedly started development in the 1990s. The engine produces at least 36,000 pounds and will improve in future. The thrust to weight ratio is around 10, close to the American F119. This brings the J-20 10 to 20 percent more thrust. It is believed the latest J-20B variant has not adopted the WS-15 yet, but it will soon. Development of the WS-15 took over 30 years, it has been delayed a few times due to technical difficulties. Once the WS-15 reaches full scale deployment status in China, the gap with the American fighter jet engine will be greatly reduced. The only thing Chinese don’t have now is the F135 turbofan engine onboard the F-35 fighter, which is the best powerplant U.S. has at the moment.
