Here is some more reporting that North Korea ballistic missile technology jump apparently came from Ukraine:
When North Korea launched a series of increasingly potent missiles last year, analysts were left scratching their heads. How had the renegade regime’s weapons program advanced so quickly?
The answer may lie more than 4,000 miles away, in eastern Ukraine, according to one nuclear expert.
Michael Elleman is convinced that North Korea’s recent missiles were powered by engines made at a once-buzzing factory in the former Soviet Union.
Elleman, a senior fellow for missile defense at the International Institute for Strategic Studies, a think tank, believes that Pyongyang acquired the 1960s Soviet-era missile engine known as the RD-250 within the past two years.
With some slight adjustments, Kim Jong Un’s government used that engine to successfully launch a medium-range missile and two intercontinental ballistic missiles, he says.
In a report published late last year, Elleman suggested that North Korea had procured the high-powered Soviet engines through a network of arms smugglers. He said it was unlikely that the transfer had been sanctioned by the Russian government or even those operating the warehouses and factories.
“These facilities have what we call ‘bone yards’ where you have old engines that are no longer in service that are just stored,” he said. “It’s not surprising that there are dozens that would be available for transfer.”
At about 6.5 feet tall and 3 feet wide, and weighing 800 or 900 pounds, the engines could be boxed and transported like a big motorcycle, Elleman suggested. [NBC News]
