The10 cm schwere Kanone 18 (10 cm sK 18) was a field gun used by Germany inWorld War II. The German army wanted a new 10.5 cm gun as well as 15 cm howitzer which were to share the same carriage. Guns are heavier than howitzers due to the longer barrel. This also led to the15 cm sFH 18. As such both weapons had a similar weight and could be carried by a similar carriage. By 1926 Krupp and Rheinmetall had specimen designs, and prototypes were ready by 1930, but was not fielded until 1933–34. BothKrupp andRheinmetall competed for the development contract, but theWehrmacht compromised and selected Krupp's carriage to be mated with Rheinmetall's gun.
It sometimes equipped the medium artillery battalion (with the15 cm sFH 18) of German divisions, but generally was used by independent artillery battalions and on coast defense duties. Some were used as anti-tank guns during the early stages of war on theEastern Front, as well as on the prototype self propelled gun"Dicker Max". Around 1,500 guns were produced until 1945. After the war it served with the Albanian and Bulgarian armies.
