Design and description
The Type 1936B design retained the hull design of the Type 1936A, but reverted to the lighter main armament of the Type 1936 to reduce topweight and improve seakeeping. The ships had an overall length of 127 metres (416 ft 8 in) and was 121.9 metres (399 ft 11 in) long at the waterline. They had a beam of 12 metres (39 ft 4 in), and a maximum draught of 4.32 metres (14 ft 2 in). The ships displaced 2,519 long tons (2,559 t) at standard load and 3,542 long tons (3,599 t) at deep load. The two Wagner geared steam turbine sets, each driving one propeller shaft, were designed to produce 70,000 metric horsepower (51,000 kW ; 69,000 shp ) using steam provided by six Wagner water-tube boilers for a designed speed of 36 knots (67 km/h ; 41 mph ). The ships carried a maximum of 835 tonnes (822 long tons) of fuel oil which gave a range of 2,600 nautical miles (4,800 km; 3,000 mi) at 19 knots (35 km/h; 22 mph). Their crew consisted of 11–15 officers and 305–20 sailors.
The Type 1936B ships carried five 12.7-centimetre (5 in) SK C/34 guns in single mounts with gun shields, two each superimposed, fore and aft of the superstructure. The fifth mount was positioned on top of the rear deckhouse. The guns were designated No. 1 to 5 from front to rear. Their anti-aircraft armament consisted of four 3.7-centimetre (1.5 in) SK C/30 guns in two twin mounts abreast the rear funnel and fifteen 2-centimetre (0.8 in) C/38 guns in three quadruple and three single mounts. The ship carried eight above-water 53.3-centimetre (21 in) torpedo tubes in two power-operated mounts. Two reloads were provided for each mount. They had four depth charge launchers and mine rails could be fitted on the rear deck that had a maximum capacity of 74–76 mines. 'GHG' (Gruppenhorchgerät) passive hydrophones were fitted to detect submarines and a S-Gerät sonar was also probably fitted. The ships were equipped with a FuMO 24 [Note 1] search radar above the bridge.
Construction and career
Z43 was originally ordered as a Type 1938B destroyer from AG Weser (Deschimag) on 28 June 1939, but the contract was cancelled when the Type 1938B design was abandoned, and the ship was reordered as a Type 1936A (Mob) destroyer. That was changed to a Type 1936B on 17 February 1941. She was laid down as yard number W1029 on 1 May 1942 at Deschimag's Bremen shipyard, launched on 22 September 1943 and commissioned on 31 May 1944 under the command of Fregattenkapitän (Commander) Carl Heinrich Lampe. After working up Z43 was assigned to the 6. Zerstörerflotille (6th Destroyer Flotilla) in October 1944.
The following month, the flotilla and the heavy cruisers Admiral Scheer and Prinz Eugen shelled Soviet positions during the evacuation of Sworbe, on the Estonian island of Saaremaa, between 20 and 24 November. In mid-December, the 6. Zerstörerflotille, which now consisted of Z43, her sisters Z35 and Z36, and the large torpedo boats T23 and T28, was tasked to lay a new minefield between the Estonian coast and an existing minefield slightly further out to sea. T23 was to escort the other ships and the destroyers were laden with 68 mines each. The mission was postponed to the night of 11/12 December because of bad weather and the flotilla sailed on the morning of the 11th. The weather gradually worsened over the course of the day and the spray and rain made navigation difficult. Having sailed a bit too far north, Z35 and Z36 blundered into the Nashorn (Rhinoceros) minefield that was only 2.5 nautical miles (4.6 km; 2.9 mi) north of the intended position of the new minefield. They both struck mines and sank around 02:00; so close to the minefield, no effort was made to rescue any survivors in the darkness.
In January and early February 1945, Z43 escorted convoys between Gotenhafen, Germany, and Libau, Latvia. Between 18 and 24 February, German forces launched a local counterattack in Samland; Admiral Scheer, Z43, and other ships provided artillery support, targeting Soviet positions near Peyse and Gross-Heydekrug. The German attack temporarily restored the land connection to Königsberg. On 27 February, the ship helped to escort the ocean liner SS Hamburg to Sassnitz. Z43 escorted Admiral Scheer and her sister Lützow from Danzig Bay to Swinemünde on 7 March and then bombarded Soviet positions near Kolberg from 11 to 18 March to cover the evacuation of the city. From 23 March to 7 April, the ship escorted Lützow and other German ships in Danzig Bay while also bombarding Soviet troops.
Z43 was struck by a Soviet bomb that failed to detonate on 9 April, but she struck a mine the following day. The explosion blew a 15-by-4-metre (49 ft × 13 ft) hole in her hull, broke her keel, and flooded the centre and aft boiler rooms. The torpedo boat T33 began a tow, but the destroyer was later able to steam under her own power to Rostock for emergency repairs that included welding several beams to the hull to strengthen it. Z43 then steamed into Warnemünde harbour to provide gunfire support for German troops ashore after having off-loaded all of her anti-aircraft guns and some of her crew. She departed Warnemünde on 2 May for Kiel, having exhausted all of her ammunition. The ship was scuttled near Flensburg the following day.
Z36 was one of five Type 1936B destroyers built for the Kriegsmarine during World War II. Completed in early 1944, the ship spent the war in the Baltic Sea, escorting German ships, laying minefields, and bombarding Soviet forces. On 12 December, a navigational error caused her to enter a German minefield as she was preparing to lay another minefield in the Gulf of Finland off the Estonian coast. Z36 struck a single mine and sank with the loss of all hands. The wreck was surveyed in 1994.
The Type 1936B destroyers were a group of five destroyers built for Nazi Germany's Kriegsmarine between 1941 and 1942, of which only three were completed and saw service. Eight ships of this design were ordered, but the orders for three ships were cancelled before construction began. Z35 was the first ship of the class to be completed and was commissioned in mid-1943. Her sister ships, Z36 and Z43, followed in 1944. Z44 was sunk during an air raid in 1944 before she was completed while Z45 was never completed. Both ships were scrapped after the war.
Z35 was the lead ship of her class of destroyers built for the Kriegsmarine during World War II. Completed in late 1943, the ship spent the war in the Baltic Sea, escorting German ships, laying minefields, and bombarding Soviet forces. On 12 December 1944, a navigational error caused her to enter a German minefield as she was preparing to lay another minefield in the Gulf of Finland off the Estonian coast. Z35 struck one or more mines and sank with the loss of all but 70 crewmen. The wreck was discovered and surveyed in 1994.
Z33 was a Type 1936A (Mob) destroyer built for the Kriegsmarine during World War II. Completed in 1943, the ship was damaged during the raid on the island of Spitsbergen in September and spent all of 1944 in Norwegian waters. She was damaged by British aircraft attacking the battleship Tirpitz in July. Z33 escorted troop convoys from northern Norway when the Germans began evacuating the area beginning in October. She ran aground in early 1945 as she was sailing for the Baltic and was badly damaged. While the ship was being towed to port for repairs, she and her escorts were attacked by Allied fighter-bombers. Z33 finally reached the Baltic in early April, but was reduced to reserve for lack of fuel. The ship was transferred to Cuxhaven and decommissioned shortly before the end of the war.
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.
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.
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.
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.
Z23 was one of fifteen Type 1936A destroyers built for the Kriegsmarine during World War II. Completed in 1940, the ship spent the war in Norwegian and French waters, escorting German ships and occasionally engaging Allied warships. In early 1941 she escorted ships between the Baltic and southern Norway before spending four months protecting ships as they transited through the Bay of Biscay. A few months after the Operation Barbarossa began in June, Z23 was transferred to northern Norway where she attempted to intercept one of the Arctic convoys returning from the Soviet Union and helped to lay several minefields.
Z25 was one of fifteen Type 1936A destroyers built for the Kriegsmarine during World War II. Completed in 1940, the ship spent most of the war in Norwegian waters, escorting German ships and laying minefields, despite venturing to France in early 1942 for the Channel Dash, escorting two battleships and a heavy cruiser home through the English Channel. She was active in attacking the Arctic convoys ferrying war materials to the Soviet Union in 1941–1942 but only helped to sink one Allied ship.
Z27 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 later that year where she remained for most of the next several years, escorting convoys and laying minefields. She sank a Soviet oil tanker in late 1942 before sailing to Germany for a refit. Upon its completion in mid-1943, Z27 returned to Norway and participated in Operation Zitronella, the raid on the island of Spitsbergen in September.
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.
Z29 was one of fifteen Type 1936A destroyers built for the Kriegsmarine during World War II. Completed in 1941, she took part in the Channel Dash in early 1942 as flagship of the escort force. Despite this venture to France, the ship spent most of the war in Norwegian waters, escorting German ships and laying minefields. Z29 participated in the indecisive Battle of the Barents Sea at the end of the year, during which she helped to sink a British minesweeper. The ship was damaged during the raid on the island of Spitsbergen in September 1943. Z29 was damaged by British aircraft attacking the battleship Tirpitz in July 1944. The ship escorted troop convoys from northern Norway when the Germans began evacuating the area beginning in October until she began an extensive refit in December.
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.
Z31 was a German Type 1936A (Mob) destroyer, which was completed in 1942 and served with the Kriegsmarine during the Second World War. She was constructed in Germany as part of Plan Z, and commissioned 11 April 1942. She spent much of the war in Arctic and Norwegian waters, taking part in the Battle of the Barents Sea on 31 December 1942. She survived the war, and was passed on to the French Navy as a war prize, serving under the name Marceau until 1958.
Z34 was a Type 1936A (Mob) destroyer built for the Kriegsmarine during World War II. Completed in 1943, the ship spent all of 1944 in Norwegian waters, and was twice damaged by British aircraft attacking the battleship Tirpitz. She escorted troop convoys from northern Norway when the Germans began evacuating the area beginning in October. Z34 was transferred to the Baltic with two of her sister ships at the beginning of 1945 and participated in the action of 28 January 1945 when they were intercepted off the Norwegian coast by a pair of British light cruisers. The ship was only lightly damaged during the battle and all three destroyers were able to disengage.
Z37 was a Type 1936A (Mob) destroyer built for the Kriegsmarine during World War II. Completed in 1942, the ship spent most of her brief career deployed in France. She participated in the Battle of the Bay of Biscay at the end of 1943 before she was accidentally rammed by the destroyer Z32 in early 1944. Towed back to port, the Kriegsmarine decided that Z37 was too badly damaged to repair and disarmed her hulk. Decommissioned later that year, she was scuttled by her crew before being scrapped by the French in 1949.
Z38 was a Type 1936A (Mob) destroyer built for the Kriegsmarine during World War II. She was laid down in 1941, and completed two years later. Her anti-aircraft armament was modified heavily under Project Barbara. She served with the 4th Destroyer Flotilla her entire time under German service, and spent much of her life escorting task forces, patrolling, laying mines, and bombarding land forces. She served in the Baltic briefly in 1943, before being reassigned to the Arctic area around Norway from 1943 to 1945, and then serving in the Baltic again in 1945.
The German torpedo boat T28 was one of fifteen Type 39 torpedo boats built for the Kriegsmarine during World War II. Completed in mid-1943, the ship was transferred to France in January 1944 and slightly damaged by British aircraft en route. She attacked Allied ships during the Invasion of Normandy in June 1944 and returned to Germany the following month. T28 was assigned to support German operations in the Baltic Sea. She escorted convoys and larger warships bombarding Soviet troops as well as bombarding them herself. In May T28 helped to evacuate troops and refugees from advancing Soviet forces. The ship was allocated to Great Britain after the war, but she was transferred to France in 1946. The French Navy renamed her Le Lorrain and recommissioned her in 1949. After serving with different units of the Mediterranean Squadron, she was condemned in 1955 and subsequently sold for scrap.
