The 21 cm Mörser 10 (21 cm Mrs 10) was a heavy howitzer used by Germany in World War I. It replaced the obsolete 21 cm Mörser 99 that lacked a recoil system. For transport it broke down into two loads. Some howitzers were fitted with a gun shield during the war. As it was also intended for siege use a concrete-penetrating shell was also used. Unusually it had two spades, one fixed at the end of the trail and another folding one about half-way down the trail.
216 were in service at the beginning of the war.[1] It was replaced by the 21 cm Mörser 16 also known as the langer 21 cm Mörser since it was merely a lighter 21 cm Mrs 10 with a longer barrel for extra range and other refinements.
