In 1939 the 21 cm Mörser 18 began appearing in the German Army Corps level Artillery Regiments, replacing the obsolescent World War I-era 21 cm Mörser 16. The gun was able to send a 113 kg (249 lb) HE shell out to a range of 14.5 km (15,857 yds), however by 1941 the German Army was seeking a longer range weapon and Krupp responded by producing a smaller 173 mm caliber increased velocity weapon utilising the same carriage, which became the Kanone 18.

The Kanone 18 quickly impressed German Artillery officers, firing a 68 kg (149 lb) HE shell out to a range of 29.6 km (18.4 mi), the real surprise was the explosive power of the shell, which was little different from the 113 kg shell of the 21 cm Mörser 18. Production commenced in 1941, in 1942 production of the 21 cm Mörser 18 was halted for almost two years so as to allow maximum production of the Kanone 18.

The 17 cm Kanone 18 was employed at the Corps level in order to provide long-range counter-battery support, as well as filling the same basic role as the 21 cm Mörser 18.

In 1944 some Allied batteries used captured 17 cm K 18s when ammunition supplies for their usual guns were disrupted by the long logistical chain from Normandy to the German border.
