J-XX 5th gen stealth fighter will have the smallest RCS among PLA's fighters, it has 360 degree battle awareness like J-20, its optical kits can detect F-35 type targets 1XX KMs away, can establish data links to almost all PLAAF, PLANAF and other land based units to utilise their fire-powers to engage targets````
its main mission tasks are to achieve battle theatre's air and sea dominace, and providing targets coordinate parameters to launched weapons (like to guide anti AC ballistic missiles)````
its radar and infrared coating can reduce its signiture from 4X% to 7X%```
its anti-radar weapon's effective range is over 180KM
its main ground and sea stricking weapons under stealth mode is SDB
its electronic warfare suite is a derivative from J-16's electronic warfare plane (dont know the exact designation yet)
so far it does not have a side weapon bay, WVR-missile can be stationed at the main weapon bay````however the export version does not have that capability, the WVR-missile is hanged on wings```
J-16 and J-15's electronic warfare fighter derivatives are more costly than J-20 and J-XX`````
based on all available infos, J-XX's radar, weapon, avionic system, stealth and aerodynamics are at the same level of F-35, some aspects are even better````however, the engine```well````the earliest date to have WS-19 would be around 2024-2025, and probably need another 3-5 years to achieve 110KN plus full thrust```
