The Skoda 30.5 cm Morser M.11 is a siege howitzer produced by Skoda Works and used by the Austro-Hungarian Army during World War I and by Nazi Germany in World War II. In 1916, the M.11 design was upgraded and the new M.11/16 was produced - the difference was mainly that the firing platform had been modified to allow for a traverse of 360 degrees. Also in 1916, a new model was released, the M.16, which had longer barrel (L/12) and longer range 12,300 metres.
