Rheintochter was a German surface-to-air missile developed by Rheinmetall-Borsig during World War II. Its name comes from the mythical Rheintöchter of Richard Wagner's opera series Der Ring des Nibelungen. The missile was a multi-stage solid fuelled rocket. It had four small varnished plywood control surfaces, resembling paddles, in the nose, six fins at the after end of the top stage, and four at the end of the main stage. It stood 6.3 m tall, with a diameter of 54 cm. The sustainer motor, located ahead of the 136 kg warhead (rather than behind, as is more usual) exhausted through six venturis between the first stage fins.
