RLV redirects here. For the World War II German Reichsluftverteidigung (RLV) see Defence of the Reich. A reusable launch system (or reusable launch vehicle, RLV) is a launch system which is capable of launching a launch vehicle into space more than once. This contrasts with expendable launch systems, where each launch vehicle is launched once and then discarded. No true orbital reusable launch system is currently in use. The closest example was the partially reusable Space Shuttle.
