The 15 cm TbtsK C/36 [Note 1] was a German medium-caliber naval gun deployed on Type 1936A (Narvik class) destroyers during the Second World War.

Design[edit]

The C/36 was a powerful gun for a destroyer, which tended to have guns varying in size from 100 to 127 mm (4 to 5 inch), a 149.1 millimeters (5.87 in) gun being more typical of a light cruiser. The construction of the C/36 differed from the SKC/25 and SKC/28 in that it had a loose barrel that could be changed from the muzzle end and that the breech block was horizontal rather than vertical. There were two variants depending upon on the mount used, the Tbts KC/36 for single mounts and the Tbts KC/36T for twin mounts. The KC/36T differed from KC/36 in that it had a breech weight in order to move the center of gravity rearwards to better balance the gun. There were also two mountings for these guns the Tbts LC/36 open backed single mount and the enclosed Drh LC/38 twin mount. A criticism of the open backed Tbts LC/36 mount was that bad weather hampered their operations. The heavy shells were also a problem since the guns lacked power assist, which meant that 40 kilograms (88 lb) shells had to be manually fed into the breech. Although the Drh LC/38 mount had an elevation suitable for anti-aircraft use its training speed of 8° sec, elevation speed of 8° sec and 8 rounds per minute were insufficient.[1]
