Saw info ch6 ucav by casc. It's number have increased in both endurance from 20 to 21 hours and ceiling from 12 km to 15 km. This is apparently the product that they are focusing on the most.
The cruising speed is twice as high as wl3 and endurance is half of that. I do wonder who exactly is looking for the higher speed and shorter endurance male ucavs that is using turbofan instead of turboprop engine.
