In a year and a half by now they in total tested and launched over 10 long range cruise missiles with between 1500 and 2000 kilometer range.
Safe to say that frequency demonstrates them being able to mass produce them and by end of this decade they may have couple hundred at least.
Yesterday it is suspected North Korea launched several long range cruise missiles, in 2 or 3 hours there may be announcement from NK.

KN-23 launched from experimental underground silo right next to Sohae satellite launch ground/station.
800 kilometer range with apogee of 50 kilometers and cold test of nuclear warhead design at 800 meters.
FADEC is not necessity for competent powerful advanced jet engines in terms of operation in grand scheme of things as a whole.
Overall engine would be slightly heavier and in some areas larger, but what matters is geometry, materials and complexity.
Except it's not to any degree since your bet is less resources as too less manpower for R&D when North Korea has longer range turbofan powered cruise missiles than Iran that rely on turbojet except maybe Paveh that is still shorter range than Hwasal-2.
North Korea is under heavy sanctions regime that is in part supported by mainland China itself so any Chinese should reflect on their own governments actions for making life of North Korean people worse just because they don't allow themselves to be pushed around by the Americans that your...
Most powerful nuclear warhead that North Korea has yield between 250 to 350 kilotons depending on estimation,
Weight of such bomb is between 250 to 350 kilograms depending on estimation for their thermonuclear warhead.
1 kiloton is 1 million kilograms and North Korea might have achieved ratio...
They reverse engineered F-5 Tiger II that has J85-GE-21 turbojet that has all traits of J79 in terms of technology, just much smaller and considerably simpler engine.
Cloning and reproduction of J85 certainly gave knowledge and experience for Iranians to reproduce FJ33 turbofan due to things...
