The 20 cm leichter Ladungswerfer (20 cm le.LdgW) was a spigot mortar used by Germany during World War II. It was used by engineers to demolish obstacles and strongpoints. It was gradually withdrawn from front-line service from 1942.
It fired High Explosive (20 cm Wgr. 40) and smoke rounds in addition to a special Harpunengeschosse (harpoon bomb) that carried a rope with hooks to clear mines or wire obstacles. The mortar was towed via the Pf. 25 handcart. Production was discontinued after 158 pieces had been delivered, and the mortars were replaced with the Granatwerfer 42.
