A real missile gap is looming in hypersonic weapons
A new “missile gap” is emerging, one that is based in fact. This is the disparity between the United States and its main competitors, Russia and China, in the field of hypersonic weapons systems. A hypersonic vehicle is one that moves through the atmosphere at a minimum speed of five times that of sound, or Mach 5. A hypersonic cruise missile travels continuously through the air employing a special high-powered engine. A hypersonic glide vehicle is launched into space atop a ballistic missile, after which it maneuvers through the upper reaches of the atmosphere until it dives towards its target. Both vehicle types can carry either conventional or nuclear weapons.
Hypersonic weapons systems could dramatically alter the existing balance of conventional military power forces between the United States and its major competitors. They could strike key military targets such as airfields, command and control centers, depots and force concentrations almost without warning. Hypersonic delivery systems are viewed as particularly useful against aircraft carriers, large surface combatants, amphibious warfare ships and even transports carrying critical military supplies.
This new gap could be far more consequential than that which concerned Senator Kennedy some sixty years ago. Hypersonic weapons are extremely difficult to track with existing air and missile defense sensors and virtually impossible to intercept. According to General John Hyten, Commander of U.S. Strategic Command: “We don’t have any defense that could deny the employment of such a weapon against us, so our response would be our deterrent force, which would be the triad and the nuclear capabilities that we have to respond to such a threat.”
