28-888: The company was a joint venture by the German shipyards AG Vulcan Stettin (located in Stettin and Hamburg ), the Krupp -owned Germaniawerft in Kiel , and AG Weser in Bremen . Design work was carried out at the facilities of these companies in Germany. At the time of IvS, the Germans were bound by the Treaty of Versailles, signed in 1919. This treaty, among other terms, demanded that all German U-boats be destroyed or given to other nations. Thus

56-444: A new company - also named Vulcan - was founded on the site of the former Stettin-shipyard. All together 34 construction numbers were started in the following years, including 18 type-VII C submarines. But because of the war only a few ships could be launched and completed. Among these were two submarines, but only one of them ( U-901 ) was ever in service while the second one ( U-902 ) was destroyed by allied air attacks before. During

84-705: A significant role in both World Wars, building warships for the Kaiserliche Marine and the Kriegsmarine later. Both yards became members of the Deschimag in the 1920s. The Stettin shipyard was closed in 1928, opened again in 1939. During World War II it exploited slave workers, and after the war, was taken over by the Polish government, while the Hamburg yard was sold to Howaldtswerke AG in 1930 and

112-565: A team of skilled and experienced German and Dutch engineers that were led by technical director Hans Techel, the former director of U-boat design at Germaniawerft. In 1925, after resolving their legal technicalities with the Dutch government, IvS finally opened its office in The Hague and the eleven-man staff that were leading the firm from the office in Kiel moved to the Dutch office. This office at

140-409: A way that IvS employees (many of whom were former Kaiserliche Marine and Reichsmarine personnel) were involved with crew training and selection, and were also allowed to take part in submarine service trials. The Germans - who were, at the time, tightly restricted from using submarines themselves - thus gained first-hand knowledge of how their prototypes worked in practice. The company also designed

168-905: The Birinci İnönü class . They were followed by the Submarino E-1 built in 1930 by the Echevarrieta y Larrinaga shipyard in Cádiz , Spain , initially for the Spanish Navy , but mainly as a prototype of the German Type I submarine and Type VII submarine . However, the Spanish lost interest in the E-1 , and it was also sold to Turkey in 1935 as the TCG Gür . In 1936 it was reported in

196-788: The Finnish Navy Vesikko ), was the prototype of the German Type II submarine, while three larger Vetehinen -class submarines served as the prototypes for the Type VII. A fifth IvS design was the small submarine Saukko , built in Helsinki by the Sandvikens Skeppsdocka och Mekaniska Verkstad shipyard, and originally planned to be deployed in Lake Ladoga . The contracts were worded in such

224-580: The Finnish Navy coastal defense ships Väinämöinen and Ilmarinen in the late 1920s. Both ships were also built by Crichton-Vulcan Oy, entering service in 1932 and 1934, respectively. The IvS was also involved in designing plans for a Royal Netherlands Navy project to build battlecruisers . Battlecruisers were deemed by some to be essential for the defense of the Dutch East Indies against possible Japanese expansion, especially as

252-519: The Gulf of Finland . Saukko , accompanied by several motor torpedo boats, was towed by the gunboat Karjala to Koivisto on 7 December 1939. Since hostilities had started before the Finnish Navy had a chance to lay defensive minefields outside their coastal forts, it was hoped that Saukko might be able to accomplish that task. A Leningrad-class destroyer and five other Soviet destroyers reached

280-560: The Locomotive Department was sold to Borsig  [ DE ] in Berlin A.G. Vulcan Stettin was founded 1851 as Schiffswerft und Maschinenfabrik Früchtenicht & Brock by the two young engineers Franz F. D. Früchtenicht and Franz W. Brock in the little village Bredow , which later became suburb of the eastern German city of Stettin . Its first ship was the small iron paddle steamer , named Die Dievenow for

308-588: The Reichsmarine was left without a submarine capability, and IvS was created to work around these restrictions. The work of the company was a major factor in the foundation of the Kriegsmarine of World War II . NV Ingenieurskantoor voor Scheepsbouw (IvS) was founded on 21 July 1922 and initially was led from the Germaniawerft in Kiel , Germany. During this time the company gradually built up

336-570: The Germans invaded the Netherlands . In 1933, the Reichsmarine established a training school in Kiel for U-boat crews, called the Unterseebootsabwehrschule ("Submarine Defence School"). This program provided for a small fleet of eight 500-tonne submarines, later doubled to sixteen. Later plans for an actual U-boat fleet included designs for submarines referred to as "Experimental Motor Boats". Deutsche Werke in Kiel

364-567: The Netherlands lacked any large surface ships. The designs were heavily influenced by the German Scharnhorst class and the final design was similar to the IvS design, because the Germans were expected to at least furnish the gun turrets for these ships, as constructing them was beyond Dutch capabilities. In the end, political disagreements delayed the decision-making process and none of the projected ships were laid down, as on May 10, 1940

392-433: The aft section and the batteries in the forward section. The name "Saukko" means European otter . The construction of Saukko began in 1928 at Sandvikens Skeppsdocka och Mekaniska Verkstad in Helsinki . The design was based on German drawings for the submarine Pu110 ("smaller, quickly assemblable submarine prototype"). Launched on 2 July 1930, Saukko was declared ready for service on 16 December 1930. At that time it

420-461: The area on 8 December, and began to shell Finnish positions. The slow Saukko could not engage the Soviet destroyer group. The next day, ice prevented Finnish boats from sortieing against the bombarding Soviet ships. When the ice was finally broken, half of the air valves on Saukko were frozen, which nearly caused the boat to capsize when it tried to submerge to lay a minefield. After these failures,

448-824: The corner of the Wagenstraat and Gedempte burgwal would be used by IvS till its dissolution in 1945. At first IvS used the old UB III and UC III boats of the Imperial German Navy as starting point for their new submarine designs. IvS first designed two submarines based on the World War I UB III submarine of the Kaiserliche Marine . Both were built by the Fijenoord shipyard in Rotterdam in 1927 and sold to Turkey , where they formed

476-529: The financial trouble was expected by additionally constructing locomotives. A subsidiary company was founded, called Abteilung Locomotivbau in Bredow bei Stettin . In 1859 the first locomotive was delivered; all together the company built about 4,000 units in Stettin until it was sold to the Berlin company Borsig . In the future larger and larger ships were built, the facilities in Stettin could no longer sustain

504-787: The media that there had been negotiations between Turkey, IvS and Dutch shipyards about a potential order for another four submarines, however, due financial concerns it came to nothing. The E-1 also attracted the attention of the Soviet Navy ; with significant modifications the E-1 became the E-2 project. Construction of the first two prototypes started in December 1934 at the Baltic Shipyard in Leningrad , using German diesel engines and electric batteries . They were followed by

532-667: The scale of the operations. The yard built the Kaiser-class ocean liners. Thus a new shipyard was built in Hamburg between 1907 and 1909. From 1911, it was named Vulcan-Werke Hamburg und Stettin Actiengesellschaft. The Hamburg yard was the scene of a week-long strike in 1918 which was only brought to a close through the reading of the War Clauses . Gustav Bauer, director of the marine engine section, supervised

560-414: The service between the cities of Stettin and Swinemünde . Several small vessels followed, while the yard continuously was enlarged. When the yard went into financial problems, in 1857 the company was taken over by some entrepreneurs and politicians from Stettin and Berlin which founded the new company Stettiner Maschinenbau Actien-Gesellschaft Vulcan . Ship construction was continued, but the solution of

588-754: The third prototype in April 1935. With further modifications to use less-expensive Soviet equipment, full production began in 1936 of the Soviet S-class submarines . In 1945 the Soviet submarine S-13 was responsible for the sinking of the German military transport Wilhelm Gustloff and the General von Steuben with heavy losses of life. From 1927 to 1933 four IvS-designed submarines were built by Crichton-Vulcan Oy in Turku , Finland . One of these, CV 707 (later

616-572: The war the yard exploited slave workers and had its own prisoner camp, part of the prisoner population engaged in anti-Nazi resistance, successfully sabotaging several constructed ships After World War II the slave workers were freed and the shipyard was finally taken over by the Polish government and the new Szczecin Shipyard was started at this site. The Szczecin Shipyard named one of its wharfs "Wulkan" and two slipways "Wulkan 1" and "Wulkan Nowa". Finnish submarine Saukko Saukko (Pu110)

644-473: The work of Hermann Föttinger on the Fottinger hydraulic transmitter known as Vulcan Coupling and Vulcan Drive or fluid coupling . In 1924, Vulcan's Hermann Rieseler invented one of the first automatic transmissions , which had a two-speed planetary gearbox, torque converter , and lockup clutch ; it never entered production. (The less-sophisticated Hydra-Matic , which used a simple fluid coupling,

672-404: Was a German shipbuilding and locomotive building company. Founded in 1851, it was located near the former eastern German city of Stettin , today Polish Szczecin . Because of the limited facilities in Stettin, in 1907 an additional yard was built in Hamburg . The now named Vulcan-Werke Hamburg und Stettin Actiengesellschaft constructed some of the most famous civilian German ships and it played

700-601: Was a small submarine that served in the Finnish Navy during the Second World War . It was designed not to exceed 100 tonnes (98 long tons; 110 short tons), as it was planned for use in Lake Ladoga , and according to the 1920 Treaty of Tartu , no nation was allowed to use naval ships of more than 100 tonnes on the lake (When completed, Saukko weighed somewhat more than this). The submarine could be divided into separate sections and transported by rail. The conning tower could be lifted off entirely. The engines were in

728-473: Was an available option on Oldsmobiles in 1940.) The original coupling further developed in collaboration with Harold Sinclair of Fluidrive Engineering of Isleworth for Daimler of Coventry and matched with a manually controlled epicyclic gearbox went into production in England in 1929. In 1928 Vulcan Stettin went bankrupt and sold its Hamburg shipyard in 1930. The AG Vulcan Stettin had been closed. 1939

756-520: Was selected to build the new submarines, and a new U-boat base was to be built at Kiel-Dietrichsdorf. Submarine components were gathered there surreptitiously, in preparation for the order to begin production. The following submarine types were initially planned: From then on more boats were built, leading up to wartime production. AG Vulcan Stettin Aktien-Gesellschaft Vulcan Stettin (short AG Vulcan Stettin )

784-546: Was the world's smallest submarine, officially weighing only 99 tonnes (97 long tons; 109 short tons). Saukko had a crew of 15 men. The outer hull was designed for icy conditions. Original plans called for Saukko to be brought to the town of Lahdenpohja on Lake Ladoga by rail, but this was never implemented. During the Winter War (1939–1940) and the Continuation War (1941–1944), the submarine operated in
