North Korea’s latest ICBM test—conducted on July 28—was not as big of a shock as the one preceding it. The message North Korea sent with its initial test on July 4 was loud and clear: the country can hit the United States mainland with its missiles, and perhaps soon with nuclear weapons. The second missile launch primarily served to drive home that point, and to do it with a vengeance. The missile North Korea launched in the late evening hours of Friday, July 28 reached an altitude of 3.7 kilometers and flew 998 kilometers, metrics that Pyongyang claims shows its ability to hit the entire territory of the United States. On Tuesday, August 1, evidence surfaced that North Korea may have carried out another test of a submarine-launched ballistic missile (SLBM) during the preceding weekend, proving the mobility of its missile-launching capabilities.
