In his 2017 New Year’s Address, Kim Jong Un mentioned (among many other things) that North Korea had “entered the final stage of preparation for the test launch of intercontinental ballistic missile.” It should be noted that this was neither the focus of his speech—which, for the most part, was a list of last year’s accomplishments—nor was it an announcement that a test would occur any time soon. Quite possibly, it was a signal to the new dealmaker-in-chief of the United States that North Korea might be ready to make a deal: to not conduct the provocative test for the right price. Still, we should consider the possibility that a test may occur in the near future. In which case, how might this happen and what might it mean?
"The missile appears to be a modified intermediate-range Musudan ballistic missile possibly equipped with a solid fuel engine, not a medium-range Rodong missile,"
The Korean Central News Agency said the Pukguksong-2 strategic weapon system was successfully test-fired Sunday. It added that the missile used solid propellants and a new engine. North Korean leader Kim Jong-un was present for the launch.
Looks like Scud derivatives.
Missiles launched are ER-SCUD
