Hypersonic weapons are weapons that move at speeds of Mach 5 or more. Presently, hypersonic weapon technology is a work in progress and these weapons are yet to become fully operational for military deployment. However, a few states have already conducted multiple tests of these weapons and the results are encouraging. They are being regarded as “game-changing” weapons, and successful hypersonic defence is considered to be difficult to achieve. At the same time, hypersonic weapons are also seen as destabilising weapons and there is a view that such weapons could fuel an arms race. This paper debates various aspects of hypersonic weapons.
