North Korea worried a lot of countries when it said it test-fired a hypersonic missile in Japan's direction

Hypersonic missiles are not only manoeuvrable and less detectable via radar than ballistic missiles, but they are also faster at around Mach 5

Are you sure about this? A ballistic missile has a terminal velocity around 5,000 m/s, that is Mach 15.

Hypersonic missiles are faster than cruise missiles.
