A larger, more capable version of the Nebelwerfer 41, this five-tube 210mm rocket launcher can fill an entire region with steel and fire. It has abandoned the unusual rear-warhead rocket design in favour of a more conventional one. Most notably, the 21cm rockets of this weapon system were adapted by the Luftwaffe for use as heavy air-to-ground rockets and, when fit with a timed or proximity fuze, anti-bomber air-to-air weapons. After the war the enormous stocks left were offered up for sale.
