Z20 Karl Galster

Prototype: Z20 Karl Galster was one of six Type 1936 destroyers built for the Kriegsmarine (German Navy) 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.

The ship returned to Germany in early 1941 for a refit and was transferred to Norway in June as part of the preparations for Operation Barbarossa, the German invasion of the Soviet Union. 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 the German attack (Operation Zitronella) 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.

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. 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.

Class History: At the outbreak of the Second World War Nazi Germany's Kriegsmarine had 21 destroyers (Ger: Zerstörer) in service, while another one was just being completed. 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.

1934 Series: This class of four ships was the first German destroyer class. It was designed around a new type of engine, using high pressure steam. This should have allowed higher speed, while saving space and crewmembers. The engine was however so complicated and prone to breakdown, that it forced the navy to assign even more very highly qualified personnel on board to operate and service them. As a result of stability problems, the range of the ships had to be restricted by navy regulations, allowing them only to use half of the fuel carried, to prevent the ships from becoming too light. The bow proved to be a faulty design, resulting in the ship to get too wet in heavy seas. This was fixed by rebuilding all four ship of the class before 1939. Four destroyers were laid down between October 1934 and January 1935. Only one ship survived the war. The ships were named after German navy personnel killed in World War I.

1934A Series: 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 in the Second Battle of Narvik. Five survived the war.

1936 Series: 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.

1936A Series: 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.

1936A(Mob) Series: 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.

1936B Series: 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.

Country: Germany is a Western European country with a landscape of forests, rivers, mountain ranges and North Sea beaches. It has over 2 millennia of history. Berlin, its capital, is home to art and nightlife scenes, the Brandenburg Gate and many sites relating to WWII. Munich is known for its Oktoberfest and beer halls, including the 16th-century Hofbräuhaus. Frankfurt, with its skyscrapers, houses the European Central Bank.
