WARR (short for Scientific Workgroup for Rocketry and Spaceflight - German: Wissenschaftliche Arbeitsgemeinschaft für Raketentechnik und Raumfahrt) is a scientific workgroup based at the Technical University of Munich (TUM). It was founded by students to compensate for the lack of a chair for space technology at TUM in 1962.
Since the establishment of the Institute of Astronautics (LRT) in 1966, the group worked on projects, starting with the successful development of the first hybrid rocket in Germany. One was launched in 1972; a second one is on permanent display at Deutsches Museum in Munich.
Besides rocketry, WARR has recently gained public attention for its successes in space elevator and Hyperloop competitions.
