The Superfluid Helium On-Orbit Transfer (SHOOT) Flight Experiment is designed to demonstrate the components and techniques necessary to resupply superfluid helium to satellites or space station based facilities. A top level description as well as the development status of the critical components to be used in SHOOT are discussed. Some of these components include the thermomechanical pump, the fluid acquisition system, the normal helium and superfluid helium phase separators, venturi flow meter, cryogenic valves, burst disks, and astronaut compatible extra vehicular activity (EVA) coupler and transfer line. The requirements for the control electronics and software are given. A preliminary description of the requirements that must be met by a satellite requiring superfluid helium servicing are given. In particular, minimum and optimum plumbing arrangements are shown, transfer line flow impedance and heat input impacts are assessed, instrumentation described, and performance parameters considered.
