Calm down! There si no aircraft, he right and it‘s not denial .. in fact you denying reality with such daydreams as if NK could develop a fighter for an eventually delivered new engine, which could replace its fighters!
Take thsi as a clear warning! The only one who is claiming nonsense is you! As such prove your point or stop posting! That‘s the way it goes …
You need to stop posting all together as you go around other forums harassing people while you contribute absolutely nothing.
As for talking about nonsense is you when two years ago you made bold assertion that China would export J-10 to North Korea.
Just because of air to air missiles shown at Self Defense 2022 exhibition were similar to Chinese when differences were evident.
Instead of admitting you have jumped conclusion you instead doubled down despite being shown more and more differences.
Not to mention you mocked one of people for them stating that those missiles shown were indigenous design by North Korea.
Your focus is on China and their industry yet do you see me making judgements on them? No, unlike you on DPRK.
Another is your nonsense assertion about Russia and Belarus being nonsense on restarting Su-25 production, as too denial about viability of creating ground attack aircraft comparable to MiG-27 in role of deep penetration attacks, powered by single engine Al-31 or Al-41.
Your criticism of me comes from uninformed perspective and frankly willfully one when seemingly nothing about you changed in two years.
Nor do you have capacity to playthrough various scenarios and possibilities, especially now when it is hardly predictable unlike years ago.
For that matter I will give you advice that you should never forget if you are ever going to comment on North Korea and for that matter Iran.
Iran and North Korea have some joint civilian and military research and development as effectively marriage of convenience since 1980's.
Now consider Russia imported vast quantities of ammunitions and weapon systems from both Iran and North Korea during SMO in Ukraine.
Reasonable to not be surprised if North Korea also orders Yak-130 and even Su-35 as a way for Russia to pay off for ammunition, missiles.
There were only 2 of Yak-130's delivered to Iran since September of 2023 thus plausible Iranians are waiting for development of Yak-130M.
Yak-130M will have SM-100 engines replacing AI-222 series and former would be ideal candidate for Saetbyol-4 to replace stand in R-13/25.
Though North Korea has innate preference for domestic manufacturing whenever possible, could try to have licensed production of SM-100.
To cut it short, do not underestimate North Korea and be informed more about it. Read a book or two such as Path of Songun by Oryx Blog.
