Wunderwaffe is a German word that literally translates to "wonder-weapon" or "miracle weapon" and was a term assigned during World War II by Nazi Germany's propaganda ministry to some revolutionary "superweapons". Most of these weapons however remained prototypes, which either never reached the combat theater, or if they did, were too late or in numbers insufficient to have a significant military effect. The V-weapons, which were developed earlier and saw considerable deployment, especially against London and Antwerp, trace back to the same pool of armament concepts. In the German language, the term Wunderwaffe now generally refers to a universal solution which solves all problems related to a particular issue, mostly used ironically for its illusionary nature.
