18 cm kurze Kanone M 80
The 18 cm kurze Kanone M 80 (short cannon) was a heavy siege howitzer used by Austria-Hungary during World War I. Designed to replace the M 61 series of siege guns the M 80 family of siege guns offered greater range and armor penetration than the older guns. The proven steel-bronze was used for the barrel and the iron carriage lacked any system to absorb recoil other than the traditional recoil wedges placed underneath and behind the wheels of the carriage. These wedges helped to absorb the recoil force and encouraged the wheels to run forward to bring the gun back into battery. Generally a wooden firing platform was constructed for these guns in action to provide a level and smooth surface. For transport the barrel was removed from the carriage by a crane and carried separately.

These siege guns were no longer useful against modern armored fortresses by the outbreak of World War I and many saw action in the field to fill the need for heavy howitzers.
