China and the U.S. have both conducted tests of new hypersonic weapons systems over the past month. Although both tests were unsuccessful, they signal continuing military competition between the two countries, which are each attempting to develop high-accuracy projectiles that can travel several times faster than the speed of sound.

On August 7, China performed an unsuccessful second test of its WU-14 hypersonic glide vehicle. The U.S. in turn tested its Advanced Hypersonic Weapon (AHW) from the Kodiak Launch Complex in Alaska on August 25.
