The 9 cm Minenwerfer M 17 (Trench mortar) was a medium mortar used by Austria-Hungary in World War I. It was developed by the Hungarian Gun Factory to meet a competition held on 3 October 1917 to replace both of the earlier light mortars the M 14/16 and the Lanz. Production was slow to ramp up and only ten weapons could be delivered in January 1918.
