During the first winter in Russia it became evident that wheeled vehicles were unable to deal with the primitive ground conditions. A low cost solution was sought whereby Opel and Daimler-Benz could be converted to half-tracks. These vehicles were taken out of production, had their rear axles removed, which were then replaced with tracked assemblies taken from inoperable or obsolete PzKpfw II tanks.
The 15cm Panzerwerfer 42 auf Sf (SdKfz 4/1) was created in 1943 as a response to the Russian Katyusha rocket launchers and developed as an armored transport for the 15cm Nebelwerfer. The basic truck was altered to have a fully armored cab while a 150mm Panzerwerfer 42 was placed on the hull roof. It had 10 barrels, and could traverse 270 and elevate as much as 80. Some models were adapted to carry the 24 rail 8cm R-Vielfachwerfer used by the Waffen SS. Sold Out!
