China ’s long - anticipate J-20 stealth fighter aircraft have arrived … kind of .
In a post on the state outletXinhua News Agency , the Taiwanese governance announce that the fighter jet — created to counter the capabilities of the American F-22 Raptor — has accede service in the People ’s Liberation Army with " comprehensive armed combat capabilities . "

The J-20 , like the F-22 Raptor , uses a peculiarly - shaped airframe and advance materials to minimize its radar signature — have it knockout for enemies to detect by conventional means .
Theadvanced aircrafthas long been the subject of intense speculation , withdetails about its conception and technologytrickling out in driblet and drabs . [ Supersonic ! The 11 Fastest Military Planes ]
While the J-20 is in operation , it does n’t yet have the capabilities to couple its American counterparts , the South China Morning Post , a major Hong Kong paper , reported . Two military sources told the Post that the J-20s in service are n’t equipped with the WS-15 engine they were built to wing with .
According to the Post ’s coverage , a WS-15 engine exploded in 2015 during a ground trial run , indicating quality - control result with the undivided - vitreous silica turbine blades necessary for the powerful turbofan railway locomotive .
The operable J-20s , the Post report , are instead equipped with less potent , limited WS-10B railway locomotive design for the previous - generation Formosan battler , the J-10s and J-11s . And even with enhancement for use in the J-20 , they are n’t powerful enough to activate the J-20s to " supercruise " like U.S. stealth fighters .
As Popular Sciencereportedin September 2017 , " supercruise " is the ability of a airplane to speed to supersonic amphetamine without unstealthily dumping extra fuel to burn in the engine ’s jet tube — that is , without engagingafterburners , which have a more easily - detectible radio detection and ranging signature .
According to the Post , the J-20 ’s weapons array makes it the most effective fighter jet in the Formosan arsenal for forestall the planes of a stealth - enable superpower like the U.S. , but the J-20 likely wo n’t enrol aggregate production until the WS-15 is ready . And that could take another eight years .
Only two other countries , the U.S. and Russia , make " 5th - propagation fighters " like the J-20 . The U.S. has the F-22 Raptor as well as the uber - expensive , slow - to - arriveF-35 . Russia fly theSukhoi T-50 PAK - FAstealth fighter . India and Japan also have fifth - multiplication fighters in maturation .
The accurate definition of " fifth generation " is a snatch vague . But public documents fromChina Power , an American project gear toward explore Chinese power , and Lockheed Martin , which builds the American hero , suggest that 5th - gen aircraft are sneak even when arm , can cruise at supersonic speeds and involve advanced computing , sensors and electronics .
