speed=The 21 cm Mörser M. 16 was a heavy howitzer used byAustria-Hungary duringWorld War I .Skoda began design in1915 for a wheeled howitzer that could be towed in a single load by a tractor. The first prototype wasn't satisfactory as it was too heavy and traversing was difficult due to the very high limber bar pressure. A second howitzer was delivered in mid-1917 that broke down into two loads for transport. This, at least, cured the traversing problem of the first weapon, as reported by the test battery assigned to the 11th Army [Ortner, p. 530] . In the meantime, however, a third prototype had been ordered as the M. 18 with a carriage based on that of the 30.5 cm Mörser M. 16 that would allow for full traverse at the price of more time needed to emplace the firing platform. It broke down into three loads for transport. No M. 18s were delivered by the end of the war, although Skoda built some modified versions as the M. 18/19 for the newly-independent Republic of Czechoslovakia where they were known as the 21 cm mozdir vz. 18. After theOccupation of Czechoslovakia in1939 the Germans adopted them under the names of 21 cm Mörser 18/19(t) or kurze 21 cm Mörser(t) although it cannot be confirmed if the Germans used them for anything other than training.References
