Hypersonic weapons fly in the upper atmosphere and reach incredible speeds of up to Mach 5, or more than 3,800 miles per hour.
The U.S. has numerous projects researching hypersonic weapons, as do Russia and China. Tuesday's test is at least the third time the U.S. has successfully used one of the weapons since September.
