North Korea's new IRBM solid-state engine... 'Possibility of utilizing Russian technology' = RFA report

North Korea successfully conducted a ground jet test of a solid-fuel engine for a new intermediate-range ballistic missile (IRBM) aimed at striking the U.S. military base in Guam, where North Korea deploys strategic assets and additional troops in the event of an emergency on the Korean Peninsula.
Analyzes are saying that Russian technology was transferred. German missile expert Dr. Robert Schumacher said, ``North Korea's solid-fuel engine for intermediate-range ballistic missiles''
may have been produced using Russian technology,'' the US Free Asia Broadcasting (RFA) reported on the 16th.

Normally, a successful ground ejection test would require dozens of tests, but North Korea suddenly announced that it was a success without going through such a process,'' he said, pointing out that ``this cannot be done without outside help.''
In particular, he said, ``North Korea would have received the engine itself, not Russia's technology,'' and ``Because North Korea's production capacity is extremely poor, we would have given North Korea the technology and asked them how to make it.''
It is unlikely that it was created in a way that could be taught." Dr. Marcus Schiller, a missile expert at Germany's ST Analytics, also said that North Korea's solid-fuel engines were developed with Russian technical assistance.
It was analyzed that it may have been manufactured. Dr. Schiller said that after North Korea first succeeded in developing an intercontinental ballistic missile (ICBM), North Korea tested a solid fuel engine for an IRBM in the past.
He pointed out that it was the same method as the Soviet Union. Dr. Schiller said, ``The easiest and fastest way to develop an IRBM would be to remove the third stage from the ICBM and use the first and second stages,'' and added, ``If the Soviet Union were to develop something like this...
"We created the intermediate-range ballistic missile SS-20 using the ceremony." Bruce Bennett, a senior researcher at the Rand Corporation in the US, also said, ``North Korea's short-range ballistic missile KN-23 is also a Russian short-range ballistic missile.
"Seeing as it was made to imitate the Sail Iskander, it is possible that this solid fuel engine was also imitated from Russian technology."
Meanwhile, North Korea conducted ground jet tests of the first and second stage solid fuel engines for the new IRBM on the 11th and 14th of this month, respectively.
This was the first time the experiment had been carried out, and he emphasized that the results were ``very satisfying.''
