Germany's 21-cm Mörser 18
21-cm Mrs 18

Krupp of Essen introduced the 21-cm Mrs 18 in 1939. 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.

The gun could be traversed the full 360° by a single man.
