In order to produce a space flight drive for propelling a spacecraft which can use the available fuel with great efficiency and which can transport heavy payloads to great heights, it is proposed that the space flight drive should comprise a fuel tank for holding a fuel, an oxidizer tank for holding an oxidizer, a combustion chamber device for the conversion of the fuel by the oxidizer, a propulsion nozzle device adjoining the combustion chamber device and a shroud device which surrounds the propulsion nozzle device annularly at least in sections for the production of an air sheath flow during a flight of the spacecraft through the atmosphere.
