The Chinese Defense Ministry confirmed the fourth test of a hypersonic nuclear delivery vehicle, which the US called an “extreme maneuver,” amid rising tensions between the two powers in the South China Sea. The test of the vehicle, which the US has dubbed the “WU-14”, was carried out on June 7 and is the missile’s fourth test in 18 months.
"The scheduled scientific research and experiments in our territory is normal, and those tests are not targeted at any country and specific goals," the ministry said in response to a report published on Thursday by the Free Beacon. The strategic strike weapon is extremely advanced and can travel at 10 times the speed of sound, or 12,231.01kph.
US missile defenses can only counter ballistic missiles and warheads that have predictable trajectories. The Wu-14 is capable of maneuvering during flight while travelling at the edge of space, and so is extremely difficult to shoot down.
