An anonymous South Korean analyst this week said a missile assembly site at North Korea's new launch complex is being expanded for the purpose of allowing more than one long-range rocket to be put together at once, Kyodo News reported.
"The North is building a new launch site designed for massive rockets in Musudan-ri," the missile specialist told the South Korean Chosun Ilbo. "They're expanding the assembly facility there by 28 meters so that they an assemble two long-range missiles simultaneously."
The Musudan-ri site in the east is assessed in Seoul to be larger and more sophisticated than an older launch complex at Dongchang-ri -- the location of North Korea's first-ever successful space launch in December.
The missile specialist said North Korea's switch to triconic warheads for medium- and long-range missiles from the more basic conic design is likely to give them additional precision.
The Iranian Shahab missile also employs a triconic warhead. The design similarities of the Shahab and the Rodong are evidence of Tehran and Pyongyang's continued missile development collaboration, he asserted.
