The fundamental analyses on the airship performance and flight dynamics and their formulation are presented. From the performance calculations of four exemplified airships, it can be concluded that only large airships the gross weight of which is more than about 500 ton have good vehicle efficiency comparing with other vehicles such as liner boat, hydrofoil ship, motor truck, rail way vehicle in the operational speed range of 50 to 200km/hr. The handling qualities of the airships are, however, very poor specifically for larger sizes because of small control powers against huge virtual mass and moment of inertia of the hull. Thus, it seems to be very difficult to maneuver the large airships at and near the hovering flight.
