TheReihenwerfer orMittlerer Schützenpanzerwagen S303(f) mit Reihenwerfer was a self-propelled barrage mortar used by theWehrmacht duringWorld War II.
After theFall of France in 1940 large amounts of French military hardware fell into German hands. Two systems that were captured in sizable numbers were theSOMUA MCLhalf-trackartillery tractor and the 81 mmBrandt Mle 27/31 mortar. Since the Germans were short of resources both were issued to German units. The SOMUA MCL was given the German designationS303(f) and the mle 27/31 was given the designationGrW 278(f).
The Reihenwerfer consisted of 20 GrW 278(f) barrels in two rows of 10 which were mounted on a common framework that was attached to a base mounted on the back of an armored S303(f) chassis. The mortars and half-tracks were converted by MajorAlfred Becker's workshop (Baukommando Becker) in Paris. All 20 barrels could be traversed 360° and elevated together from +35° to +90°, with the outer barrels pointing slightly outwards to increase the spread of the barrage. The vehicle carried 90 rounds of ready use ammunition and each barrel held a single round at the top of the tube until fired by pulling a lanyard. The round then slid down the tube until it hit a firing pin which launched it. In action, all 20 barrels were fired in rapid succession, but not simultaneously to saturate the target area. The Reihenwerfer was deployed by German units in Northern France during theNormandy landings.[2]
