There has been a lot of speculation about what exactly North Korea fired into the East Sea in recent days.
According to military sources in Seoul, South Korea and U.S. joint intelligence forces have reportedly concluded that the projectiles were new rockets, 300-milimeter in caliber, fired from a multiple rocket launcher.
The rockets, believed to be an improvement on the North's 240-millimeter-caliber models, can travel up to 2-hundred kilometers, putting South Korea's army, navy and air force combined military command in Daejeon well within range.
Daejeon is located some 1-hundred-50 kilometers south of Seoul and experts say, that this means Pyongyang has a new type of weapon capable of striking regions further south.
North Korea currently has up to 5-hundred multiple rocket launchers deployed along the 38th parallel.
