Union Giesserei A.G.

Full name in German: Union-Giesserei, Lokomotivfabrik & Schiffswerft, Konigsberg

Union Giesserei was a German engineering company based in Konigsberg, East Prussia,
Union Giesserei did not get any contracts from the newly formed Deutsche Reichsbahn and negotiations with the Reichsbahn proved largely fruitless. This led to severe economic problems in the company during the mid-1920s. The shipyard fared better as the German authorities had a strategic interest in maintaining shiprepairing capability in the East. However in 1930 Union Giesserei was declared bankrupt, and from 17 March it became a subsidiary of the F. Schichau GmbH. The shipyard was fully integrated in the Schichau group in 1931, came under Soviet control in 1945 and later became the Russian-owned Yantar Shipyard.
