| Notes | The K39(t) was a Skoda designed piece which could be used as a heavy field gun or coastal gun. The Germans used twelve of them during the opening phases of operation Barbarossa and these were issued to Artillerie-Abteilung 767 and 768. These weapons were also used to bombard Odessa, Leningrad and Sevastopol. The gun had to be split into three loads for transportation and took six to eight hours to be ready for firing. Around twenty six were used as coastal guns. |
