## Abstract

A tethered aerostat with a ground based deployment, extended duration and recovery system to accommodate a weather vaning deployed aerostat while maintaining a supply of a lift gas by having a rotatable tether pipe and a hollow tether. Included is a rotatable tether pipe device assembly with rotor and stator components disposed in an air tight housing assembly to provide a ground based gas maintenance system. An aerostat deployment buoyancy control maintenance and combined recovery platform is provided. The tethered aerostat systems and method increase deployment duration and allow more systems to be controlled and maintained on the ground without interrupting aerostat operational capabilities.
