The 21 cm Mörser 16 (21 cm Mrs 16) or langer 21 cm Mörser was a heavy howitzer used by Germany in World War I and World War II.
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 Thirties with rubber-rimmed steel wheels to allow for motor traction in one piece with a limber under the trail and generally removed the gunshield.
Combat service
In German service it used two shells, the 21 cm Gr 18 (HE) that weighed 113 kilograms (249 lb) and the 21 cm Gr 18 Be concrete-piercing shell of 121.4 kilograms (268 lb) with a filler of 11.61 kilograms (25.6 lb) 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 and equipped units in secondary theaters.
The Swedes bought a dozen weapons in 1918 from the Germans and they remained in service until 1950. The Swedes had their own concrete-piercing shells, the 210 tkrv 51/65-ps R-/33 weighing 120.75 kilograms (266.2 lb), which had dispersion problems as the Finns found out.
The Finns bought four of these from the Swedes 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. They were put into reserve after the war and remained there until the late 1960s before being discarded.
