Air-Breathing Hypersonic
An air-breathing hypersonic vehicle is a type of missile or aircraft that travels at incredibly high speeds, typically over five times the speed of sound, by using engines that draw in oxygen from the surrounding atmosphere to burn fuel. This differs from rockets, which carry their own oxygen supply.

TECHNICAL DEFINITION
An air-breathing hypersonic system, such as a missile or aircraft, achieves sustained hypersonic flight (Mach 5+) within the Earth's atmosphere by utilizing air-breathing propulsion engines, primarily scramjets or advanced ramjets, which ingest atmospheric oxygen for combustion, offering greater efficiency and range compared to rocket-propelled systems.
BACKGROUND
The Hypersonic Attack Cruise Missile is an Australian-American scramjet-powered hypersonic air-launched cruise missile project, the successor of the Hypersonic Air-breathing Weapon Concept (HAWC) and the SCIFiRE hypersonic programs.
