A total of 101 examples were built by Rheinmetall between 1938 and 1943. It was not popular in service as its barrel length and weight were very large proportionally for its shell damage, and its performance was not much better than the established K16 design. The Heer also fielded many larger caliber guns which were more effective at engaging
fortifications. This caused its production to be terminated in August 1943. Many were used in static coastal installations, removing all mobility drawbacks and resulting in successful service over the K16. == See also ==
