During the 1980s, the German government took increasing interest in the project for use as a reusable launch system, resulting in the project gaining official support and work commencing on an enlarged version of the vehicle, known as Saenger II. Work on the project was terminated during 1995 as a consequence of the high projected costs of proceeding and perceived limited performance gains (in comparison to existing expendable launch systems such as the Ariane 5 rocket).
