The 8 cm Granatwerfer 34 (8 cm GrW 34) was the standard German infantry mortar throughout World War II.[1] It was noted for its accuracy and rapid rate of fire, although it was less effective when being operated by poorly trained crews.


The weapon was of conventional design and broke down into three loads (smooth bore barrel, bipod, baseplate) for transport.[1] Attached to the bipod were a traversing handwheel and a cross-leveling handwheel below the elevating mechanism.[2] A panoramic sight was mounted on the traversing mechanism yoke for fine adjustments. A line on the tube could be used for rough laying.[3]

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.[3]
