German World War II destroyers

At the outbreak of the Second World War, the German Navy, the Kriegsmarine, had 21 destroyers (Ger: Zerstörer) in service, while another one was just completing. These 22 vessels - comprising 3 classes (Type 34, 34A and 36) - had all been built in the 1930s, making them modern vessels (no destroyers remained in German hands following the close of the First World War). Including that final pre-war vessel, a further 19 were brought into service during the war and more were captured from opposing navies, including the Italian Navy (Regia Marina) after the Italian Armistice with the Allies in 1943.

German destroyer classes were generally known by the year of their design. Because of their size, use and weaponry, some vessels classified as "fleet torpedo boats", Flottentorpedoboot, are also described.

Class general characteristics are taken from the first of each class, and may differ slightly for individual ships, particularly when they were refitted. Post-war, some surviving ships had significant changes to armament.

Zerstörer 1934
This class of four ships was the first German destroyer class built since World War I, laid down between October 1934 and January 1935. They were not very good ships. Built rapidly, they were too wet in heavy seas, which could make their forward guns unusable, there were structural weaknesses and machinery problems. The engines were newly designed high pressure turbines that promised much but disappointed once installed: maintenance was difficult and they caused excessive vibration. In addition, the class' range was limited (less than half of equivalent British ships) and they had limited magazine capacities (again half of the British equivalents). Only one ship survived the war. The ships were named after German navy personnel killed in World War I.

The ships were:

Zerstörer 1934A
Twelve destroyers laid down between July and November 1935. They were only slightly modified from the design of the preceding 1934 class and continued their predecessors' limited endurance and magazine capacity - factors which contributed to the heavy German losses at the Second Battle of Narvik. Five survived the war.

Zerstörer 1936
These 6 ships (of 26 planned) ordered under the 1935 Program were improved and enlarged versions of the 1934 and 1934A classes. Most of the serious faults of the earlier ships had been resolved: engine reliability and the structural integrity was much improved and they were much better seagoing ships, shipping less water through an improvement in the design of the bows. Despite this, five of this newer type were also lost at Narvik in April 1940.

Zerstörer 1936A "Narvik"
Eight destroyers intended to carry new 150 mm (5.9 inch) guns in single turrets with a twin turret at the bow. The twin mountings were not ready in time and so singles were first used, and the twins fitted later (only to four ships: Z-23, Z-24, Z-25, Z-29). Anti-aircraft armament was substantially improved.

Despite reusing earlier ship designs as a basis, with modifications to improve seaworthiness, the ships were wet in heavy seas, especially fitted with heavy turrets. After much effort, the problem was traced to a newly designed stern. However, this problem was somewhat offset by the fact that the twin mount was fully enclosed and had a high maximum elevation, allowing limited use against aircraft.

These ships reverted to the traditional German practice of giving torpedo ships numbers rather than names. Four survived the war.

Zerstörer 1936A (Mob)
When war broke out in 1939, planned new destroyer classes were cancelled and twelve additional 1936A vessels (Z.31 to Z.42, although the last three were to be cancelled) were ordered with slight modifications to speed construction and save materials. The 150 mm twin turrets had been manufactured for planned, but never built, "O" class battlecruisers. In war service, the engines were more reliable than in earlier ships but at the end of the war, heavy corrosion was discovered.

Seven of this sub-class were built: one was sunk, another two were severely damaged and not repaired. The remaining four were war booty allocated to the Allies.

Zerstörer 1936B
The main armament of this class reduced back to single mounted 127 mm guns and the anti-aircraft armament was increased. The efficacy of this change was not proven in high seas as this sub-class only operated in the Baltic and coastal waters.

Eight ships to this design were ordered, but the orders for Z.40, Z.41 and Z.42 (all three ordered from Germaniawerft at Kiel) were replaced by orders for three Spähkreuzer ("scout cruisers"), to be numbered Sp.1, Sp.2 and Sp.3 respectively. Two ships (Z.44 and Z.45) were never completed, being suspended in 1944 and scuttled incomplete after the war. The three that were commissioned were all lost.

Zerstörer 1936C
Five ships of this class were ordered in 1942 and 1943 (Z.46 - Z.50), all from A.G. Weser at Bremen; none were launched, just two were started - Z.46 and Z.47 - and both were bombed by Allied aircraft while under construction and were scrapped on the slipways in 1945. This design was a response to the vulnerability to air attack of early German destroyers and would have used six new 128 mm Flak 40 guns (originally designed for the Luftwaffe) as dual purpose weapons in twin mountings. The number of smaller caliber anti-aircraft guns would have also been increased.

Zerstörer 1938A/Ac
In order to provide support for larger German warships operating far from their bases, the development of large ocean going destroyers started in the late 1930s. They would have had dual power systems to enable long endurance cruises. Twenty-four of these were planned under Plan Z but were not actually ordered - the concept was developed further into the Spähkreuzer (see Type 1936B above).

Zerstörer 1938B
Ships of this class would have been small destroyers designed to patrol and operate in Baltic and coastal waters, but would have had quite big operational range for such purpose, and could have also been used in high seas. Twelve ships were ordered in the summer of 1939, but after the start of World War II, all were cancelled.

Zerstörer 1942
Experimental test-bed destroyer powered by diesel engines for long-range operations. Based on design of unbuilt Type 1938B destroyer, with six diesels driving three shafts, with an estimated speed of 36 kn and an operating radius of 13500 mi. One example (Z.51) was laid down in 1943 and launched in 1944, but was sunk by Allied bombers on 21 March 1945 while fitting out.

Zerstörer 1942C
While Z.51 was a testbed for diesel propulsion, the Type 1942C destroyer was a production class of large, diesel powered destroyers. They were planned to have a revised armament, with six 128 mm C/41M dual purpose main guns, and an all-new anti-aircraft armament, with three 5.5 cm Gerät 58 intermediate calibre anti-aircraft guns and a close-in armament of 14 30-mm cannon in seven twin mounts, with eight torpedo tubes.

Five of these ships (Z.52–Z.56) were ordered from A.G. Weser at Bremen and were laid down in 1943, but none were completed, being cancelled in July 1944 and broken up on the slips. A further two ships (Z.57 and Z.58) were ordered from Germania Werft at Kiel, but were cancelled before construction started.

Zerstörer 1945
Project for high-speed design reverting to steam-turbine propulsion. Unbuilt.

Destroyer sized craft
The German Navy had several torpedo boat classes with displacements between 1,000 and 1,300 tons (for example the Mowe-class Fleet Torpedo boats and Torpedo boat type 35). They sat between torpedo-equipped fast attack boats (known to the Allies as E-boats) and the destroyers. In 1939, the Germans started work on new designs that were a response to the weaknesses of earlier designs. These "Fleet Torpedo Boats" (Flottentorpedoboot) were large, 1,755 tons, and more able as escorts and for anti-aircraft defence as well as torpedo attacks and they were comparable in most respects to some of the British destroyer classes. They were all laid down during the war.

Flottentorpedoboot 1939 (Elbing class)
The first of the fleet vessels, they were comparable in most respects - size, armament, and use - to standard British destroyer types. Fifteen were laid down between 1940 and 1942, in the Schichau shipyard in Elbing (now Elbląg) and from that the Allies referred to them as the Elbing-class.

The last was commissioned at the end of 1944; three survived the war and served in Allied navies. The ships were numbered T22 to T36.

Flottentorpedoboot 1940
Following the capitualation of the Netherlands, Dutch shipyards were contracted to build 24 boats based on a Dutch design. Only three of these 2,600 ton vessels were launched. The three that were launched were moved to the Baltic in 1944 for work but none were completed.

Flottentorpedoboot 1941
This was a development of the 1939 class, with bigger engines and more anti-aircraft weapons. Fifteen were laid down or launched from 1942 but by the end of the war none had been completed.

Flottentorpedoboot 1944
These were to have been ocean-going vessels, as opposed to North Sea or coastal vessels, capable of operating with the fleet, with greater range and an emphasis on anti-aircraft weaponry. Nine were ordered in March 1944, the order was subsequently cancelled without any building having started.

Torpedoboot Ausland
Several destroyer sized ships were captured by the Germans and put into service as Torpedoboot Ausland

Captured ships
Some destroyers were captured and used by the Germans.

ZH1
The Dutch destroyer Hr.Ms. Gerard Callenburgh was built by RDM Rotterdam and launched 12 October 1939. The Dutch attempted to scuttle this ship during the German invasion but the destroyer was salvaged and completed under German control with technical guidance from Blohm & Voss. Commissioned as the ZH1 on 11 October 1942. The Germans retained most of the Dutch armament and equipment. The ZH1 spent most of its life on trials in the Baltic but transferred to Western France via the English Channel in November 1943. When the western allies invaded Normandy in 1944 the German destroyers based in western France attempted to interdict the invasion armada. The German squadron was intercepted by an Allied force - the 10th Destroyer Flotilla (HMS Tartar, Ashanti, Eskimo, Javelin, HMCS Haida, Huron, and ORP Błyskawica, Piorun). In the night action ZH1 was torpedoed and sunk by Ashanti on 9 June 1944, 33 men were lost.

ZF2
The hull of the French Le Hardi-class destroyer L'Opiniatre was captured intact and 16% complete in Bordeaux and the Kriegsmarine intended to complete her for service. Since French armament was not available and for standardisation with the rest of the German Navy, 12.7mm guns and German pattern torpedo tubes were ordered. Work proceeded tardily until all progress was abandoned in July 1943. The hull was eventually broken up on the slip

ZG3 (Hermes)
The Greek destroyer Vasilefs Georgios was captured in damaged condition after the fall of Greece, then repaired in Greece with assistance from the Germaniawerft and commissioned by the Kriegsmarine as the ZG3 or the Hermes. She was the only major Kriegsmarine surface ship in the Mediterranean Sea during World War II, and she was involved in escorting convoys to North Africa and the Aegean Islands.

Hermes detected and depth charged the Royal Navy submarine HMS Splendid off Capri, Italy, on 21 April 1943 forcing it to surrender; Splendid was scuttled by her crew. Hermes was damaged by air attacks off Tunisia. Hermes had to be scuttled in La Goulette, Tunis on 7 May 1943.
