The 24-cm-Kanone 3 (24 cm K 3) was a German heavy siege gun used in the Second World War by the first battalion of Artillerie-Regiment 84. Four were in service when Germany invaded Poland, assigned to the first two batteries of I./AR 84,[1] and in the Battle of France.[2] By Operation Barbarossa all three batteries were equipped with two guns apiece.[3] This situation did not change for the next two years.[4]
