The Type 1936 destroyers, also known as the Z17 class, were a group of six destroyers built for Nazi Germany's Kriegsmarine during the late 1930s, shortly before the beginning of World War II. All six sister ships were named after German sailors who had been killed in World War I. [1] They were engaged in training for most of the period between their completion and the outbreak of war, although several did participate in the occupation of Memel in Lithuania, in early 1939.
When the war began in September 1939, the sisters helped to lay minefields in the German Bight and then helped to lay multiple minefields off the British coast in late 1939 and early 1940. All but one participated in Operation Weserübung, the German invasion of Norway in April; they were all sunk or scuttled during the naval Battles of Narvik except Z20 Karl Galster which was refitting at the time. She was transferred to France in September where she engaged British ships several times. After a refit, the destroyer was transferred to Norway in preparation for Operation Barbarossa, the Axis invasion of the Soviet Union, in June 1941. Z20 Karl Galster mostly spent the rest of the year escorting convoys. After another refit, the ship briefly returned to Norway in mid-1942 until she was badly damaged in July when she ran aground and had to return home for repairs. The destroyer returned to Norway in December and remained there until November 1943, participating in Operation Zitronella in September.
Plagued by engine problems, the ship was under repair from November to August 1944 and then spent the next six months on convoy escort duties in southern Norway and laying minefields. Z20 Karl Galster was transferred to the Baltic Sea in early 1945 where she escorted refugee convoys and also evacuated refugees herself from the advancing Soviet forces before the German surrender in May. The ship was allotted to the Soviets after the war and she was converted into a training ship in 1950 before she was scrapped in 1958.
These six ships were improved and enlarged versions of the Type 1934 and Type 1934A classes. Even though they were designed before the earlier ships were completed, the stability problem was partially fixed by reducing top-weight which allowed their full oil capacity to be used, their turning radius was slightly reduced and the bow was reshaped to reduce the amount of water coming over the bow in a head sea. These changes improved their seakeeping ability in comparison to the previous destroyer classes. They still retained the over-complicated and troublesome boilers of the earlier ships. [2] [3]
The first three ships built had an overall length of 123.4 meters (404 ft 10 in) and the later trio were modified while under construction with a clipper bow that increased their overall length to 125.1 meters (410 ft 5 in); all six ships were 120 meters (393 ft 8 in) long at the waterline. They had a beam of 11.75 meters (38 ft 7 in), and a maximum draft of 4.5 meters (14 ft 9 in). The Type 36s displaced 2,411 long tons (2,450 t) at standard load and 3,415 long tons (3,470 t) at deep load. [4] The destroyers had a metacentric height of 0.95 meters (3 ft 1 in) at deep load. [2] They were divided into 15 watertight compartments of which the middle 7 contained the propulsion and auxiliary machinery and were protected by a partial double bottom. Active stabilizers were initially fitted to reduce roll, but they proved to be ineffective and were replaced by bilge keels on all the destroyers except Z20 Karl Galster before April 1940. They had a complement of 10 officers and 313 enlisted men, plus an additional 4 officers and 19 enlisted men if serving as a flotilla flagship. [5]
The Type 1936s were powered by two Wagner geared steam turbine sets, each driving a single three-bladed 3.25-meter (10 ft 8 in) propeller using steam provided by six high-pressure Wagner water-tube boilers with superheaters that operated at a pressure of 70 atm (7,093 kPa ; 1,029 psi ) and a temperature of 450 °C (842 °F). The turbines, designed to produce 70,000 metric horsepower (51,000 kW ; 69,000 shp ), were intended to give the ships a speed of 36 knots (67 km/h ; 41 mph ). [2] The first four ships were able to conduct full sets of speed trials before the start of the war and they handily exceeded their designed speed, reaching 39–41.5 knots (72.2–76.9 km/h; 44.9–47.8 mph) from 72,100–76,500 shp (53,800–57,000 kW; 73,100–77,600 PS). [6] They were fitted with a pair of 200-kilowatt (270 hp) turbogenerators plus two 80-kilowatt (110 hp) and a single 40-kilowatt (54 hp) diesel generators. [7] The ships carried a maximum of 739 metric tons (727 long tons) of fuel oil which gave a range of 2,050 nautical miles (3,800 km; 2,360 mi) at 19 knots (35 km/h; 22 mph). [2]
The Type 1936 ships were armed with five 12.7 cm (5 in) SK C/34 guns in single mounts with gun shields. One pair each was superimposed, fore and aft of the superstructure and the fifth mount was positioned on top of the rear superstructure. They carried 600 rounds of ammunition for these guns, which had a maximum range of 17.4 kilometres (19,000 yd), and could be elevated to 30° and depressed to −10°. Their anti-aircraft armament was made up of four 3.7 cm (1.5 in) SK C/30 anti-aircraft guns in single mounts, with 8,000 rounds of ammunition, and six 2 cm (0.79 in) C/30 anti-aircraft guns in single mounts, with 12,000 rounds of ammunition. The ships carried eight above-water 53.3 cm (21 in) torpedo tubes in two power-operated mounts amidships. [2] Four depth charge throwers were mounted on the sides of the rear deckhouse and they were supplemented by six racks for individual depth charges on the sides of the stern. Sufficient depth charges were carried for either two or four patterns of sixteen charges each. [8] Mine rails could be fitted on the rear deck that had a maximum capacity of sixty mines. [2] 'GHG' (Gruppenhorchgerät) passive hydrophones were fitted to detect submarines and an active sonar system was installed by the end of 1939. [9]
Z20 Karl Galster had a FuMO 21 [Note 1] search radar installed in 1942 and her anti-aircraft suite was upgraded several times over the course of the war. By the end, it consisted of six 3.7 cm guns and fifteen 2 cm weapons. [10]

Z17 Diether von Roeder and Z19 Hermann Künne were two of the destroyers that escorted Adolf Hitler when Germany occupied Memel in March 1939. When the war began in September, Z21 Wilhelm Heidkamp and Z22 Anton Schmitt were still working up so only Z17 Diether von Roeder, Z18 Hans Lüdemann, Z19 Hermann Künne and Z20 Karl Galster were deployed to lay minefields off the German coast. They were soon transferred to the Skagerrak where they inspected neutral shipping for contraband goods and were joined there by Z21 Wilhelm Heidkamp by the end of the month. [1]
Beginning in mid-October and continuing through February 1940, the Kriegsmarine began using its destroyers to lay offensive minefields off the British coast on dark nights with little to no moonlight. The sisters (Z22 Anton Schmitt became operational in January) participated in five of the eleven sorties and their mines helped to sink a British destroyer and 121,348 gross register tons (GRT) of merchant shipping. [13]
Z21 Wilhelm Heidkamp was the flagship for Group 1 for the Norwegian portion of Operation Weserübung in April 1940. The group's task was to transport mountain infantry to seize Narvik. The ships began loading troops on 6 April in Wesermünde and set sail the next day. [14]
On 9 April, Z22 Anton Schmitt and Z18 Hans Lüdemann landed troops at the entrance to the Ofotfjord while their sisters proceeded to Narvik and Elvegårdsmoen to unload their troops. Z21 Wilhelm Heidkamp sank an old coastal defense ship in Narvik harbor after an attempt to get her captain to surrender failed. All of the destroyers were short on oil; fueling proceeded very slowly and only three destroyers had completed doing so by the following morning, although Z18 Hans Lüdemann and Z19 Hermann Künne were in the process of doing so when the five destroyers of the British 2nd Destroyer Flotilla appeared shortly after dawn. Caught totally by surprise, the initial torpedo salvo sank Z21 Wilhelm Heidkamp and Z22 Anton Schmitt and lightly damaged Z19 Hermann Künne. British shells also damaged Z18 Hans Lüdemann and crippled Z17 Diether von Roeder. The German destroyers unsuccessfully returned fire with several torpedoes passing underneath the British ships. [15]
On the night of 12/13 April, the Germans received word to expect an attack the following day by British capital ships escorted by a large number of destroyers and supported by carrier aircraft. The battleship Warspite and nine destroyers duly appeared on 13 April, although earlier than expected, and caught the Germans out of position. Z19 Hermann Künne was the first ship to spot the approaching British ships and alerted the other ships. The other operable destroyers (Z17 Diether von Roeder was still under repair in Narvik harbor) joined Z19 Hermann Künne as she fell back and engaged the British ships at long range from behind a smoke screen, inflicting only splinter damage; they were not damaged by the British return fire. By the early afternoon, the Germans had exhausted most of their ammunition and the destroyers were ordered to retreat to the Rombaksfjorden (the easternmost branch of the Ofotfjord), east of Narvik, where they might attempt to ambush any pursuing British destroyers. Z19 Hermann Künne's captain misunderstood the signal and headed north into the Herjangsfjord where he ran the ship aground. She had fired off all of her ammunition, including practice and star shells; her depth charges were rigged for demolition and they were set off once the crew had abandoned ship. A pair of British destroyers followed her into the fjord and put a torpedo into the wreck for good measure, breaking off her stern. [16]
Z18 Hans Lüdemann still had some ammunition and torpedoes left and took up position at the Straumen narrows with Z2 Georg Thiele to give the two other remaining destroyers time to scuttle themselves at the head of the fjord. The pursuing British destroyers initially engaged Z18 Hans Lüdemann, which had opened fire at a range of about 3 miles (4,800 m) to little effect. Her four remaining torpedoes were fired blindly, one of which was observed to pass under a destroyer and all missed. Shortly afterwards the British ships hit the German destroyer twice, destroying No. 4 and No. 5 guns and damaging No. 3 gun, the only ones that could bear on the British ships. Z18 Hans Lüdemann's captain decided to withdraw as she could no longer fight the British ships and beached the ship at the head of the fjord. He ordered her rigged for demolition and abandoned ship while Z2 Georg Thiele continued to fight. Several hours later, after the latter ship was destroyed, British destroyers approached and found Z18 Hans Lüdemann still intact, the demolition charges having failed. Following their orders to destroy all of the German destroyers, they torpedoed her wreck. [17]
When the British appeared at the harbor mouth they initially thought that they were being fired upon by coastal artillery in the smoke and confusion, but a reconnaissance aircraft spotted Z17 Diether von Roeder. The destroyer Cossack moved through the sunken freighters to investigate and opened fire at point-blank range. She set the German ship's stern aflame, but Z17 Diether von Roeder's return fire was devastating. The British destroyer was hit at least seven times that caused her to run aground. Other British ships returned fire, but the gunners had abandoned ship once their ammunition was exhausted and only the three-man demolition party was still aboard when a British destroyer approached. They lit the fuses and ran ashore and the depth charges blew her apart before she could be boarded. [18]
After a refit that prevented Z20 Karl Galster from participating in Operation Weserübung, the ship was sent to Norway for escort duties. Later that year she was transferred to France later as the flagship of the 5th Destroyer Flotilla (5. Zerstörerflotille), where she conducted anti-shipping patrols and laid a minefield in the English Channel with little success. [19]
The ship returned to Germany at the end of the year for a refit and was transferred to Norway in June as part of the preparations for Operation Barbarossa. Z20 Karl Galster spent some time at the beginning of the campaign conducting anti-shipping patrols in Soviet waters but these were generally fruitless. She escorted a number of German convoys in the Arctic later in the year until engine problems sent her back to Germany for repairs. The ship returned to Norway in mid-1942, but was badly damaged when she ran aground in July and did not return until December. Z20 Karl Galster participated in Operation Zitronella, the German attack on the Norwegian island of Spitzbergen, well north of the Arctic Circle, in September 1943. Plagued by engine problems, the ship was under repair from November to August 1944 and then spent the next six months on convoy escort duties in southern Norway when not laying minefields. [20]
Around March 1945, Z20 Karl Galster was transferred to the Baltic Sea where she helped to escort convoys of refugee ships and also rescued evacuees herself in May, around the time that Germany surrendered. [21] When the surviving German warships were divided between the Allies after the war, the ship was eventually allocated to the Soviet Union. Z20 Karl Galster was handed over in 1946 and renamed Prochnyy. The ship was converted into a training ship in 1950 and then became an accommodation ship in 1954. She was scrapped four years later. [22]
The Battles of Narvik were fought from 9 April to 8 June 1940, as a naval battle in Ofotfjord and as a land battle in the mountains surrounding the north Norwegian town of Narvik, as part of the Norwegian Campaign of the Second World War.
The German destroyer Z1 Leberecht Maass was the lead ship of her class of four destroyers built for the German Navy during the mid-1930s. Completed in 1937, two years before the start of World War II, the ship served as a flagship and spent most of her time training, although she did participate in the occupation of Memel in early 1939.
The German destroyer Z2 Georg Thiele was one of four Type 1934-class destroyers built for the German Navy (Kriegsmarine) during the mid-1930s. She was named after Georg Thiele, a Korvettenkapitän who commanded the Seventh Half Flotilla of torpedo boats. Completed in 1937, two years before the start of World War II, the ship spent most of her time training although she did participate in the occupation of Memel in early 1939.
The German destroyer Z4 Richard Beitzen was one of four Type 1934 destroyers built for the German Navy (Kriegsmarine) during the mid-1930s. Completed in 1937, the ship spent most of her time training although she did participate in the occupation of Memel in early 1939. At the beginning of World War II in September 1939, the ship was initially deployed to blockade the Polish coast, but was soon transferred to the Kattegat where she inspected neutral shipping for contraband goods. In late 1939 and early 1940, the ship laid two offensive minefields off the English coast that claimed 17 merchant ships. Z4 Richard Beitzen was in reserve during the Norwegian Campaign of early 1940 and was transferred to France later that year, where she made several attacks on British shipping.
Z10 Hans Lody was a Type 1934A-class destroyer built for Nazi Germany's Kriegsmarine in the mid-1930s. 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 the ship laid multiple offensive minefields off the English coast that claimed nine merchant ships and she crippled a British destroyer during one of these missions.
Z11 Bernd von Arnim was a Type 1934A-class destroyer built for Nazi Germany's Kriegsmarine in the late 1930s. At the beginning of World War II, the ship was initially deployed to blockade the Polish coast, but she was quickly transferred to the German Bight to lay minefields in German waters. In late 1939 the ship made one successful minelaying sortie off the English coast that claimed one British warship and seven merchant ships. During the early stages of the Norwegian Campaign, Bernd von Arnim fought the British destroyer Glowworm while transporting troops to the Narvik area in early April 1940, but neither ship was damaged during the action. The ship fought in both naval Battles of Narvik several days later and had to be scuttled after she exhausted her ammunition.
Z12 Erich Giese was a Type 1934A-class destroyer built for Nazi Germany's Kriegsmarine in the late 1930s. At the beginning of World War II, the ship was used in the German Bight to lay minefields in German waters. In late 1939 the ship made one successful minelaying sortie off the English coast that claimed two merchant ships. While returning from that sortie, she torpedoed a British destroyer without being detected and continued on her way. During the early stages of the Norwegian Campaign, Erich Giese fought in both naval Battles of Narvik in mid-April 1940 and was sunk by British destroyers during the Second Battle of Narvik.
Z13 Erich Koellner was a Type 1934A-class destroyer built for Nazi Germany's Kriegsmarine in the late 1930s. At the beginning of World War II, the ship was still working up. In early 1940 she made two successful minelaying sorties off the English coast that claimed six merchant ships. During the early stages of the Norwegian Campaign, Erich Koellner fought in both naval Battles of Narvik in mid-April 1940 and was severely damaged by British ships during the Second Battle of Narvik. The ship was scuttled by her crew shortly afterwards.
Z14 Friedrich Ihn 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 Friedrich Ihn. At the beginning of World War II, the ship was initially deployed to blockade the Polish coast, but she was quickly transferred to the German Bight to lay defensive minefields in German waters. In late 1939 and early 1940, the ship laid multiple offensive minefields off the English coast that claimed 18 merchant ships and a destroyer. Ihn was under repair during the Norwegian Campaign of early 1940 and was transferred to France later that year.
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.
Z16 Friedrich Eckoldt was a Type 1934A-class destroyer built for Nazi Germany's Kriegsmarine in the late 1930s. It was named after Kapitänleutnant Friedrich Eckoldt (1887–1916), the commander of torpedo boat V 48, who was killed when his boat was sunk during the Battle of Jutland on 31 May 1916.
Z17 Diether von Roeder was one of six Type 1936 destroyers built for the Kriegsmarine in the late 1930s. Completed in 1938, the ship spent most of her time training although she did participate in the occupation of Memel in early 1939. At the beginning of World War II in September, the ship was initially deployed to lay minefields off the German coast, but was soon transferred to the Skagerrak where she inspected neutral shipping for contraband goods. In late 1939, the ship helped lay an offensive minefield off the English coast that claimed seven merchant ships.
Z18 Hans Lüdemann was one of six Type 1936 destroyers built for the Kriegsmarine in the late 1930s. Completed in 1938, the ship spent most of her time training. At the beginning of World War II in September 1939, she was initially deployed to lay minefields off the German coast, but was soon transferred to the Skagerrak where she inspected neutral shipping for contraband goods. In late 1939, Z18 Hans Lüdemann helped to lay two offensive minefields off the English coast that claimed one destroyer and twenty merchant ships.
Z19 Hermann Künne was one of six Type 1936 destroyers built for the Kriegsmarine in the late 1930s. Completed at the beginning of 1939, the ship spent most of her time training although she did participate in the occupation of Memel a few months later. At the beginning of World War II in September, she was initially deployed to lay minefields off the German coast, but was soon transferred to the Skagerrak where she inspected neutral shipping for contraband goods. In late 1939, Z18 Hans Lüdemann helped to laid four offensive minefields off the English coast that claimed two British destroyers and thirty-eight merchant ships.
Z20 Karl Galster was one of six Type 1936 destroyers built for the Kriegsmarine in the late 1930s. Completed in early 1939, the ship spent most of her time training. At the beginning of World War II in September, she was initially deployed to lay minefields off the German coast, but was soon transferred to the Skagerrak where she inspected neutral shipping for contraband goods. In late 1939 and early 1940, Z20 Karl Galster helped to laid three offensive minefields off the English coast that claimed one British destroyer, a fishing trawler, and twenty merchant ships. After a refit that prevented her from participating in the German invasion of Norway in April, the ship was sent to Norway for escort duties. Later that year Z20 Karl Galster was transferred to France, where she made several attacks on British shipping.
Z21 Wilhelm Heidkamp was one of six Type 1936 destroyers built for the Kriegsmarine 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.
Z22 Anton Schmitt was one of six Type 1936 destroyers built for the Kriegsmarine in the late 1930s. Completed after the beginning of World War II in September 1939, she helped to lay an offensive minefield off the English coast that claimed one small ship. During the German invasion of Norway in April 1940, the ship was tasked to attack Narvik and was sunk during the First Naval Battle of Narvik on 10 April.
Z28 was one of fifteen Type 1936A destroyers built for the Kriegsmarine during World War II. Built as a flotilla leader with fewer guns than her sister ships, she was completed in 1941. The ship spent most of the first few years of her service in Norwegian waters, escorting convoys and laying minefields. Z28 ran aground in early 1943 and spent the rest of the year under repair. The ship briefly returned to Norway at the beginning of 1944, but was transferred to the Baltic shortly afterwards to support minelaying operations in the Gulf of Finland. That was her primary focus through July and then she began escorting German cruisers as they bombarded Soviet troops ashore in addition to German convoys evacuating people from Finland and the Baltic States.
Z30 was one of fifteen Type 1936A destroyers built for the Kriegsmarine during World War II. Completed in 1941, the ship was transferred to Norwegian waters in early 1942 where she remained for most of the rest of her career, escorting convoys and laying minefields. She played a minor role in the indecisive Battle of the Barents Sea at the end of the year and was damaged during the raid on the island of Spitsbergen in September 1943.
The Type 1934 destroyers, also known as the Z1 class or Leberecht Maass class after the lead ship, were a group of four destroyers built for the German Navy during the mid-1930s, shortly before the beginning of World War II. The ships were engaged in training for most of the period between their commissioning and the outbreak of war, although they did participate in the occupation of Memel in Lithuania, in early 1939. Z3 Max Schultz collided with and sank a German torpedo boat shortly before the war began on 1 September 1939. All four ships were named after German officers who had been killed in World War I.
