This study first analyses in depth the typical mission profile of the tug, determining the typical ∆V requirements and mission durations. This is used to trade off various configurations and propulsion systems, to determine the necessity of active cooling of the tanks and identify the key limitations arising from both needing to be refuelled and to refuel other tanks. From this, a preliminary design for the refuelling tug is presented.
