The defense against the cruise missiles is more challenging and difficult since they remain in the atmosphere during all their flight time at low altitude. Currently, the United States has different anti-cruise missiles including the Standard Missile-2, Standard Missiles-6, Medium Extended Air Defense System (MEADS), and Evolved Seasparrow Missile (ESSM) systems. These systems are designed for supersonic cruise missiles.

At a time when existing missile defenses can’t guarantee success against the ballistic missiles, a whole new challenge has been posed by hypersonic vehicles. Many people believe that after a certain time period the effectiveness of ballistic missile defenses will grow. In that situation, hypersonic weapons’ deployment is important. However, as of now, the Hypersonic Glide Vehicles (HGVs) and Hypersonic Cruise Missiles (HCMs) are solutions looking for a problem.

What’s New in Hypersonic Weapons

Speed, maneuverability, and low-altitude travel are major traits of hypersonic weapons which are not comparable to the existing ballistic or cruise missiles. Cruise missiles lack speed while the ballistic missiles can’t maneuver. Hypersonic weapons travel normally at speeds greater than Mach 5 at lower altitudes with maneuverability making them harder to detect and kill than the legacy ballistic and cruise missiles.

Major global powers are engaged in building, testing and deploying hypersonic weapons. Among them are the United States, Russia, and China. India and France are also working on hypersonic research and development. Russian’s demonstration of “Avangard” in 2018 added urgency to the U.S. plans to expedite hypersonic developments. The United States is also looking at various options to defend against Russian and Chinese hypersonic threats with parallel developments of its own weapons. Russia and China would also be considering options of defensive capabilities after the United States has rushed to develop this capability.

Among the options being discussed to protect against hypersonic threats are directed-energy weapons, hit-to-kill capabilities, space-based interceptors, a laser weapon mounted on an unmanned airborne platform to track and destroy missiles in their boost-phase, and cyber-attacks on the enemy’s command and control systems.
