I wondered what engine the North Koreans used.
it is very similar to the Global Wawk, therefore the engine must have adequate power
The Global Wawk = Powerplant: 1 × Rolls-Royce F137-RR-100 turbofan engine, 34 kN (7,600 lbf) thrust
New similar NK UAV, which engines the DPRK certainly has available list of Russian engines (or Chinese equivalents thereof) to be used without afterburner
1)Mig-17 Klimov VK-1F turbojet , 26.5 kN (6,000 lbf) thrust
2)Mig-19 Tumansky RD-9B turbojet , 25.5 kN (5,700 lbf) thrust
3)Mig-21 Tumansky R-13 turbojet 39.9 kN (8,970 lbf) thrust or
Tumansky R-25-300 turbojet, 40.18 kN (9,030 lbf)
4) Mig-23 MLA R-35F-300, turbojet 83.82 kN (18,840 lbf)
5)Mig-29 Klimov RD-33 turbofan, 49.42 kN (11,110 lbf)
or
6)Since it is the Iranians who have had access to the Global Wawk, in collaboration with the DPRK they could have developed a copy of the Turbofan Rolls-Royce, which they could then also use for piloted aircraft and also equip it with afterburner
