The 8 cm Granatwerfer 34 (8 cm GrW 34) was the standard German infantry mortar throughout World War II.[2] It was noted for its accuracy and rapid rate of fire.


The weapon was of conventional design and broke down into three loads (smooth bore barrel, bipod, baseplate) for transport.[2] Attached to the bipod were a traversing handwheel and a cross-leveling handwheel below the elevating mechanism.[3] A panoramic sight was mounted on the traversing mechanism yoke for fine adjustments. A line on the tube could be used for rough laying.[4]

The 8 cm GrW 34/1 was an adaptation for use in self-propelled mountings. A lightened version with a shorter barrel was put into production as the kurzer 8 cm Granatwerfer 42.

The mortar employed conventional 8 cm 3.5 kg shells (high explosive or smoke) with percussion fuzes. The range could be extended by fitting up to three additional powder charges between the shell tailfins.[4]
