Schwere Wehrmacht Schlepper Panzerwerfer 42
In August 1944, Martini-Hütte in Salzkotten received an order to examine if the s.W.S. would be suitable as chassis for the Panzerwerfer 42. At least one vehicle of the 15cm Panzerwerfer 42 auf Selbstafhrlafette schwerer Wehrmachtsschlepper mit Behelfspanzerung – a self propelled armoured 15cm rocket launcher – was finished near the end of war. The vehicle was armed with a 15cm Panzerwerfer 42 known from the Sd. Kfz. 4/1 and had a fully armoured body.
