Figure 1. This graphic shows the maximum altitudes and corresponding projected ranges of the two Hwasong-14 missiles that North Korea tested in July. The highly lofted rocket trajectories achieved in the July 4 and the July 28 tests are shown on the left side of the figure. The center and right side of the figure show alternative rocket trajectories that could instead have been flown with loft angles optimized for maximum range instead of for maximum altitude.

Figure 2. The red and blue lines on this graph show the distances that two different models of the Hwasong-14 missile could carry payloads of varying weights. Where those lines intersect with the yellow rectangle show the approximate range (given on the lower, horizontal axis) to which the rockets might carry an atomic bomb of the type North Korea may have.
