This U.S. Missile Can Kill Any Target on the Planet (In Less Than an Hour)
Meet the Common Hypersonic Glide Body.
by Caleb Larson
The United States Navy and Army are working together to develop and eventually field a hypersonic glide body in the early- to mid-2020s. The missile, called the Common Hypersonic Glide Body, or C-HGB, differs from other glide vehicles that are being designed by DARPA or other military branches.
Unlike other glide bodies, the C-HGB is conical rather than wedge-shaped. The cone shape is seen as a more conservative design compared to wedges, which are still under development, though both missiles operate in a similar fashion. Using a rocket to get up to optimal speed and altitude, the glide vehicle separates from the rocket body and glides toward a target hundreds or even thousands of miles away at supersonic speeds.
Though cone designs are a less risky choice from a design standpoint, they are considered less maneuverable and therefore less survivable during their terminal flight phase when maneuvering around or through enemy missile defenses.
