The arms race towards hypersonic weapons

They are manoeuvrable weapons that can fly at speeds in excess of Mach 5, five times the speed of sound. The speed of sound is Mach 1, and speeds upto Mach 5 are supersonic and speeds above Mach 5 are hypersonic. Ballistic missiles, though much faster, follow a fixed trajectory and travel outside the atmosphere to re-enter only near impact. On the contrary, hypersonic weapons travel within the atmosphere and can manoeuvre midway which combined with their high speeds makes their detection and interception extremely difficult. This means that radars and air defences cannot detect them till they are very close and little time to react. (Read More)
