Laser propulsion is a propulsion system using laser energy in order to generate thrust. Laser propulsion system generates thrust using the blast wave induced by laser energy instead of combustion process. As a kind of application of laser propulsion, air‐breathing laser‐spike engine can be suggested for a MAV aircraft in atmospheric flight. Since laser propulsion uses air as propellant in the atmosphere, and laser facilities exist in the remote place, this engine can become a solution of propulsion system of MAV. Initial results related with this 2‐Dimensional micro air‐breathing laser‐spike engine for supersonic flight is reported for the experiment and numerical simulation. Suggested 2cm diameter projectile for supersonic flight was shown ca 300 KW power laser requirement at the altitude of 9km and 1200KW at the sea level.
