Hypersonic flight refers to travel at speeds greater than five times the speed of sound, or Mach 5. This technology allows aircraft and missiles to move extremely fast, significantly reducing travel time. Hypersonic vehicles can glide through the atmosphere or fly in a powered state, utilizing advanced propulsion systems. The development of hypersonic technology has implications for both military and civilian applications. For instance, it could enable faster global travel and improve the effectiveness of defense systems. Countries like the United States and China are actively researching and testing hypersonic vehicles to enhance their capabilities.
