H-20 will be designed to close the current capability gaps in the PLA. This means irreplaceable missions like:
1. Sustained, high intensity conventional strike against Australia/Hawaii
2. Sustained, high intensity conventional strike against CONUS
3. High yield nuclear strike against CONUS, including against deeply buried targets
4. Long range maritime interdiction, including in the Atlantic and off the US coast
Missions like AEW are tactical and much less important and can be performed by a variety of existing. Its not impossible that the H-20 can in some way perform this mission thanks to the flexibility of modern sensors but I cannot see the PLAAF making any compromises on the core features of the H-20 to support this mission, which are 1. all aspect broad band VLO stealth 2. range 3. payload.
