German destroyer Z21 Wilhelm Heidkamp
1938 Type 1936 destroyer
Z21 Wilhelm Heidkamp was one of six Type 1936 destroyers built for the Kriegsmarine (German Navy) in the late 1930s. Completed a few months before the start of World War II in September 1939, the ship served as a flagship throughout her career. She briefly patrolled the Skagerrak where she inspected neutral shipping for contraband goods. Z21 Wilhelm Heidkamp later helped to lay four offensive minefields off the English coast that claimed two British destroyers, 2 fishing trawlers, and twenty-seven merchant ships. During the German invasion of Norway in April 1940, she sank a Norwegian coastal defense ship off Narvik and was crippled with the opening shots of the First Naval Battle of Narvik on 10 April, with the loss of 81 crewmen. The ship sank the following day.
Design and description
Z21 Wilhelm Heidkamp had an overall length of 125.10 meters (410 ft 5 in) and was 120 meters (393 ft 8 in) long at the waterline. The ship had a beam of 11.80 meters (38 ft 9 in), and a maximum draft of 4.50 meters (14 ft 9 in). She displaced 2,411 long tons (2,450 t) at standard load and 3,415 long tons (3,470 t) at deep load. The two Wagner geared steam turbine sets, each driving one propeller shaft, were designed to produce 70,000 PS (51,000 kW; 69,000 shp) using steam provided by six Wagner boilers for a designed speed of 36 knots (67 km/h; 41 mph).
