This (GJ-X?) is clearly a clean slate design whose only similarity with the CH-7 is its cranked kite configuration. At 137ft / 42m, it is likely the largest and most capable UCAV ever made. Its higher wing sweep angle is more consistent with a strike role flying at high subsonic speed than an ISR role flying at medium subsonic speed. Lengthwise, its looks to be around 20 meters long (50% of width), which would permit very long IWB(s).
I agree, this GJ-X seems like a natural next generation, larger and more refined platform than GJ-11 as a land based UCAV.
The planform is definitely more oriented for strike and payload than WZ-X's flying wing geometry (which favoured endurance), and the cranked kite geometry versus the GJ-11/B-21 style continuous leading edge platform suggests to me that they wanted the central fuselage to be fairly long without incurring additional weight that would occur if they maintained the same dimensions but utilised a continuous leading edge design.
Which will naturally lead to the question of powerplants.
Previously we had floated the idea of a single non AB WS-10 or two non AB WS-13/21 engines, and while both options may be viable for this aircraft, I wonder if they may even be ambitious enough to put a non AB WS-15 variant on it (though perhaps its bypass ratio would be less favourable for this role).
Needless to say, I think with WZ-X and this GJ-X, if they do enter service along these proportions and dimensions, then they would prove to be formidable "optimized" flying wing UAV/UCAV sizes for land based operation. The benefits in long range and long endurance ISR and strike this go without saying.
