The 15 cm TbtsK C/36 was a German medium-caliber naval gun deployed on Type 1936A (Mob) destroyers during the Second World War. It was designed because the Oberkommando der Marine thought that the 12.7 cm (5.0 in) guns of the Type 1936 and 1936A destroyers would potentially be inferior to those of possible enemies. The guns caused serious issues when actually placed upon the ships as they added significant weight high up on the ships. To deal with this increase in weight, the destroyers had one gun removed, sometimes with a twin gun being used in order to keep five guns.

Z8 Bruno Heinemann was a Type 1934A-class destroyer built for Nazi Germany's Kriegsmarine in the mid-1930s. After the start of World War II in September 1939, she blockaded the Polish coast and searched neutral shipping for contraband. In late 1939 and early 1940 the ship made three successful minelaying sorties off the English coast that claimed 17 merchant ships. Bruno Heinemann participated in the early stages of the Norwegian Campaign by transporting troops to the Trondheim area in early April 1940. The ship was transferred to France a year later to escort German ships that used the French ports on the Atlantic coast. She was returning to France in early 1942 when she struck two mines and sank off the coast of Belgium.
