CMK RA055 22,5 cm Minenwerfer M.15

The Minenwerfer M.15 is an Austro-Hungarian, 225 mm heavy trench mortar (so-called mine thrower) from the First World War. The initial velocity of the demolition shell from this mortar was up to 170 m / s, with a maximum range of approx. 680 meters. Serial production continued in the years 1915-1918 and led to the creation of about 930 pieces of these weapons.

The Minenwerfer M.15 was developed and put into series production at the Böhler plants as an alternative to the German Erhardt 25 cm Schwerer Minenwerfer trench mortar licensed for the Imperial-Royal Army, the production process of which turned out to be too demanding for the Böhler plants. The M.15 minenwerfer was front-loaded and had an unthreaded barrel line. It did not have very precise aiming means, which made it not very precise, and the projectiles fired from it often flew over the target. The main task of the Minenwerfer M.15 was to support the attacks of its own infantry on enemy trench lines. The mortar could fire missiles with combat gas. Two development variants (M.16 and M.17) were created in the course of production.
