21-cm Mörser 181
21-cm Mrs 181
Krupp of Essen introduced the 21-cm Mrs 18 in 1939.1 Production started with it getting priority over the 17-cm K 18, but this was changed in 1942 when it was realized that the 17-cm K 18 fired a similar sized shell at a longer range.1
The gun could be traversed the full 360° by a single man.1
