Hypersonic

Hypersonic refers to speeds that are five times greater than the speed of sound (around 3,836 kilometers per hour or 2,375 miles per hour at sea level). Objects traveling at hypersonic speeds, like certain missiles or experimental aircraft, can glide or maneuver through the atmosphere. This capability poses unique challenges for detection and interception in military contexts. In addition to defense applications, hypersonic technology may also influence future air travel, potentially reducing flight times significantly across long distances. Overall, hypersonic speed represents a frontier in propulsion and aerospace technology.
