A vehicle suitable for use in high-altitude applications use may include a gas impermeable body and a flexible barrier separating the body into multiple sections or compartments. The compartments may include a lift compartment for holding lift gas, such as lighter than air gas, and a ballast compartment for holding a ballast, such as heavier than air gas. A valve may permit passage of the ballast from the ballast compartment to an exterior of the body. The body may have an oblong shape, with fins attached to an exterior back end thereof. The vehicle may have only internal ballast compartments, without including a hopper external to the body.

A gimbaled truss assembly is disclosed including a frame rotatably mounted in a gimbal mount, and a truss rotatably mounted within the frame. The truss is configured to retain a propulsion system. The frame and the truss rotate independently of one another. A fastening system for mounting the propulsion system to the truss includes vibration isolators. A plurality of braces are coupled to the gimbal mount. The braces conform to the external surface of an air vehicle on which the assembly is to be attached.
