21 cm Mörser 18 is a German heavy howitzer.


The 21 cm Mörser 18, despite designated as a "mortar" being more a howitzer, was developed in the late 1930's as a modern replacement of its predecessor, the 21 cm Mörser 16. It was produced from 1939 to 1942 in small numbers. The gun fires high explosive shells as well as concrete piercing rounds capable to penetrate one meter of armed concrete. Its most innovative part was the carriage: The barrel recoiled in its cradle, but, in addition, the whole top carriage, which carried the barrel and its cradle, recoiled across the main part of the carriage. This system damped out the recoil forces almost completely. A platform below the carriage could be lowered to rotate the whole weapon quickly in a new direction by just one man. The 21 cm Mörser 18 was used by independent heavy artillery units and, for example, played a prominent role in the siege of Sevastopol and the bombardment of the Allied troops following the Anzio landings.

In Battlegroup42, the 21 cm Mörser 18 is only available as a stationary weapon. It has limited traverse to the left and to the right, but can rotated slowly 360° with the whole carriage. It will appear on some maps in the next release of the mod.
