One of the discussions that Markus Schiller and I have about North Korea’s ballistic missile program centers on the SS-N-6 aka BM-25 aka Musudan ballistic missile. I was skeptical of the missile at first — although we’ve subsequently seen a larger version on parade, a second stage on the Unha that looks like an SS-N-6, and NASIC has reported that North Korea has deployed the missile. There are also reports of static engine tests.
Markus and Robert Schmucker, however, still have their doubts. I am posting a paper, Explaining the Musudan: New Insights on the North Korean SS-N-6, in which they argue that North Korea’s SS-N-6 capabilities are rather less than we commonly believe.
I am not so sure, but I am happy to host that discussion in the comments.
