The United States announced that it has successfully tested a hypersonic missile on March 20, 2020. This is a follow-up exercise of the first joint US Army and Navy flight experiment conducted in 2017.

The hypersonic missile can travel faster than the current nuclear-capable ballistic and cruise missiles. They travel at low altitudes and switch direction in flight and as they do not follow a predictable arc like traditional missiles, it is harder to track and intercept them.
