LASER DEFENSE SYSTEM AND HIGH ALTITUDE AIRSHIP

摘要

A space based laser defense system according to the embodiment of the present invention, including a high-altitude airship (HAA). The high-altitude airship (HAA) includes a balloon filled with a lifting gas, and a focusing optics that focuses a laser beam from an outside of the high-altitude airship at a target. The laser beam may come to the high altitude airship from a space-based laser (SBL) that stays in a geostationary Earth orbit.
