Z15 Erich Steinbrinck was a Type 1934A-class destroyer built for Nazi Germany's Kriegsmarine in the mid-1930s. The ship was named after the First World War German naval officer Erich Steinbrinck. At the beginning of World War II on 1 September 1939, the ship was initially deployed to blockade the Polish coast, but she was quickly transferred to the North Sea to lay defensive minefields. In late 1939 and 1940 the ship laid multiple offensive minefields off the English coast that claimed 24 merchant ships and a destroyer. Steinbrinck was under repair for most of the Norwegian Campaign of early 1940 and was transferred to France later that year.

Nürnberg was a German light cruiser of the Leipzig class built for the Kriegsmarine. She was named after the city of Nuremberg and had one sister ship, Leipzig. Nürnberg was laid down in 1934, launched in December of that year, and completed in November 1935. She was armed with a main battery of nine 15 cm (5.9 in) guns in three triple turrets and could steam at a speed of 32 knots. Nürnberg was the longest-serving major warship of the Kriegsmarine, and the only one to see active service after the end of World War II, though not in a German navy.
