22.5 cm Minenwerfer M 15
Encyclopedia
The 22.5 cm Minenwerfer M 15 was a heavy mortar
used by Austria-Hungary
in World War I
. It was developed by Böhler
as an alternative to the German Ehrhardt
25 cm schwere Minenwerfer
which Böhler was having problems building under license. It was a muzzle-loading, smooth-bore mortar that had no recoil system whatsoever. The entire mortar had to be levered around to aim at new targets. It was not particularly accurate and bombs often fell over in flight and landed on their sides which caused a lot of duds in soft ground. It fired high-explosive and gas shells. For transport two wheels from the Gebirgsgechütz M 99 were used.
The M 17 version of this weapon had an elevation screw with a double thread and reinforced trunnion
bearings. It's unclear how the M 16 differed from the earlier model.
