21 cm Mörser 16

History

It was based on the earlier 21 cm Mörser 10 but had a longer barrel, a gun shield and other refinements. Originally, it broke down into two loads for transport but the Germans rebuilt surviving guns during the 1930s with rubber-rimmed steel wheels to allow for motor traction in one piece with a limber under the trail and generally removed the gun shield.

Combat service

In German service, it used two shells, the 21 cm Gr 18 (HE) that weighed 113 kg and the 21 cm Gr 18 Be concrete-piercing shell of 121.4 kg with a filler of 11.61 kg of TNT.

They remained in first-line use with the Germans until replaced by the 21 cm Mörser 18 by about 1940. Afterwards, they were used for training, although some equipped units in secondary theaters.

Sweden bought a dozen weapons in 1918 from the Germans and they remained in service until 1950. Finland bought four of these from Sweden during the Winter War, although they did not participate in the war because the Finns lacked vehicles strong enough to tow their great weight to the front. This had been rectified before the Continuation War and the Finns equipped the 10th Separate Super-Heavy Artillery Battery with them for the duration of the war. The Swedes had their own concrete-piercing shells, called 210 tkrv 51/65-ps R-/33 by the Finnish army, weighing 120.75 kg, which had dispersion problems as the Finns found out. The weapons were put into reserve after the war and remained there until the late 1960s before being discarded.
