How an old engine makes the J-20 fight like an old fighterThe older engine, the WS-10B, is basically the same kind used in the J-11 and J-10 fighters in 19.Without the new engine, the J-20 can’t supercruise, or fly above the speed of sound, without igniting its afterburners like the U.S.’s F-22 and F-35 can. 9 that the Chengdu J-20 stealth jet had officially entered into service as a combat-ready platform - but inside sources say it’s a long way from fighting fit and has an embarrassing flaw.Citing military sources with knowledge of the J-20’s development, the South China Morning Post reported that the jets that entered service didn’t feature the engine China custom-built for the platform but used an older one instead.The result is an underpowered, less stealthy jet that can’t cruise at supersonic speeds and is therefore not a true fifth-generation fighter.The Posts’ sources pinned the jet’s troubles on a test in 2015 in which the custom-built engine, the WS-15, exploded - something they attributed to China’s inability to consistently build engines that can handle the extreme heat of jet propulsion.
