An air vehicle comprises a vehicle body and a propulsion assembly. The vehicle body has the shape of a wing airfoil to generate lift when air flows over the vehicle body. The vehicle body has a body longitudinal axis and substantially planar port and starboard sides of composite material, and includes first and second hulls that are secured together side-by-side, the hulls having longitudinal axes that are substantially parallel to the body longitudinal axis and two substantially planar side walls at least one of which is of composite material. Each hull defines a separate fluid chamber that is filled with a fluid that is at least partially buoyant. The propulsion assembly is secured to the vehicle body port and starboard sides. The propulsion assembly includes port front and rear engines and starboard front and rear engines, wherein at least two of the engines have independently controlled thrust vectors.
