hypersonic glide vehicles (HGV)

Hypersonic glide vehicles (HGVs) are advanced weapons that travel at speeds greater than Mach 5 (about five times the speed of sound) and can maneuver during flight. Unlike traditional missiles, they are launched into the atmosphere via missiles, then glide unpowered toward their target at incredibly high speeds. Their agility and speed make them difficult to detect and intercept, posing significant strategic and defense challenges. HGVs are designed for precise, rapid delivery over long distances, potentially impacting security dynamics globally due to their speed, maneuverability, and difficulty in defense.
