The numbers here for WJ-700 looks pretty good. Max speed of 650 km/h with 8 to 14 hour endurance, 15km ceiling, 3.5t max takeoff and 480 kg payload. It's a different class of UCAV than WL-3. I wonder if they'd be interesting in a higher speed HALE UCAV like this. CH-6 is twice its size and have 21 hour endurance. If I had to guess, both of these are only for export market and China would want a flywing design for higher end UCAV powered by turbofan engine.
