Abstract: A catamaran airship is tethered to a portable and mobile housing. The roof of the housing will be the landing and take-off place for the airship. Many types of vehicles—truck, ship—can be a mobile base for the housing and its airship. This is primarily a visual surveillance and long-range communication system for day and night, and in all-weather. This system can survey large areas over long periods of time, economically and noiselessly.
