North Korea's 'hypersonic' missile: What we know

Hypersonics are defined as being able to travel at velocities of at least five times the speed of sound -- Mach 5, or more than 6,100 kilometres (3,800 miles) per hour. As well as their sheer speed, they can manoeuvre in mid-flight, making them much harder to track and intercept than traditional projectiles.
