The Schwerer Wehrmachtschlepper (sWS) was developed as a medium half-track and used to transport materials to front-line troops or as a towing car the light artillery. However, on the large rear flat load compartment other applications have now been developed. One modification was the Panzerwerfer 42 auf sWS, a 10 barreled 15 cm Nebelwerfer 42 rocket launched placed over an armored ammunition storage compartment. The rocket launcher, developed as unit to produce smoke displays, had been quickly utilized as real artillery in a position to introduce high-explosive ammunitions. It may shoot the rocktes with impressive and deadly effects. The first structure of transport vehicle was strengthened with extra shields to guard the crew through the enemy fire and from negative effects of the rocket launcher.
