lol, no. Their last missile test would have easily reached Washington D.C had it been fired at a normal trajectory instead of going so high to keep it close to Japan.
Estimated range on their current ICBM is 8,100 miles, enough to land anywhere in the US mainland.
US intel assesses that if the Norks don’t fire them into such a high trajectory, the RV will probably survive. High trajectory means a lot more stress.
If they were developed completely domestically that’s even worse. Aside from acquiring actual engines, it’s just as likely they acquired designs and manufacturing. Your article predates the launch of the Hwasong-15 missile which unlikely the Hwasong-14 had a two chamber engine which is basically identical to the RD-250.
That being said, the last 3 tests were completely successful in terms of boost stage. From your article:
“Two years have passed since the beginning of the development of technology until launch, these terms are exceptional,” Radchenko said, referring to North Korea’s missile program. “No one can … implement this project in such terms, even a space power … But they succeeded. They used the finished product. That’s all we can say.”
Any way you slice it, they made a huge leap in the last few years. Please back up your statement that “they haven’t got the experience in producing them to do so with any consistency or the money to develop a serious large scale program without starving the country to death.”
For starters, large scale isn’t my concern. One missile could be more than enough.
