North Korea Continues to Test Hypersonic Weapons

North Korea carried out its second ballistic missile test in six days yesterday, with the latest appearing to be a hypersonic weapon that traveled a reported 430 miles at a speed of Mach 10, underscoring the country's recent advancements in the global hypersonic arms race. While the DPRK claimed the first launch last Wednesday was also a hypersonic missile, SouthKorea says it only traveled at a speed of Mach 6. The launch yesterday led the FAA in the United States to briefly ground all flights on the west coast. South Korea's Joint Chiefs of Staff called the latest launch a "grave threat to international peace and stability."
