North Korea announces second hypersonic missile test was successful

North Korea claimed Thursday to have conducted the second successful test flight of a hypersonic missile, days after leader Kim Jong Un vowed to bolster his military forces despite pandemic-related difficulties.

The official Korean Central News Agency said the Central Committee of the ruling Workers’ Party expressed "great satisfaction" at the results of the missile test, which was observed by leading weapons officials. 

Hypersonic weapons, which fly at speeds in excess of Mach 5, or five times the speed of sound, could pose crucial challenges to missile defense systems because of their speed and maneuverability. It’s unclear whether and how soon North Korea could manufacture such a high-tech missile, but it was among a wish-list of sophisticated military assets that Kim disclosed early last year, along with a multi-warhead missile, spy satellites, solid-fueled long-range missiles and underwater-launched nuclear missiles.
