North Korea has tested the Hwasong-15 an intercontinental missile that can reach the American soil on paper.  How does the new Pyongyang carrier work?    LETTERA43  20171129

North Korea has claimed the success of the latest intercontinental missile test (Icbm), "the most powerful" so far developed, capable of striking every corner of the United States: the Hwasong-15 is the last clutch that allows the leader Kim Jong-un to proclaim the country as "nuclear power".  For a more detailed analysis of features, experts will need more time.

The rocket, according to the Kcna, has touched an altitude of 4,475 km and the distance of 950 km after a 53-minute flight. These values are in line with the preliminary estimates of US, South Korea and Japan.  According to some hypothesis, if the launch angle was not large but of a standard type, the final trajectory would be about 13,000 km.  The carrier can "mount a heavy and large nuclear head" by offering "Honda's best-in-class tactical and technological advantages", another missile tested twice in July with positive results.

The new missile is associated with a "home-propelled 9-axis launch vehicle" that can now be produced "in the amount that the country wants."  The test confirmed the "reliability" of the fuel-powered engine and the technologies set for returning to the atmosphere, the Kcna said.  Precisely on this last point, analysts have expressed the heaviest doubts: even if the missile has so far been the longest trajectory, the North seems to be still weak on technology to return to the atmosphere, a key element for Icbm carriers.
