When was the navy that was donated the LKL "Kursis" (M51) by Germany established?
Lithuanian Naval Force The Lithuanian Navy is the naval arm of the Lithuanian Armed Forces. Though formally established on 1 August 1935 its roots stretch back as far as naval engagements on the Baltic Sea in the Medieval period. Lithuanian naval units saw some service with Soviet naval forces during World War II, and the navy has been re-established in its own right and continues to expand since Lithuania's independence in 1990.
U-50-class submarine The "U-50" class was a class of four ocean-going submarines or U-boats planned for the Austro-Hungarian Navy (German: "Kaiserliche und Königliche Kriegsmarine "or" K.u.K. Kriegsmarine" ) during World War I. The design of the boats was based on the Project 835 design purchased from the German firm of Germaniawerft in July 1915. The Navy authorized Ganz Danubius to begin construction of the submarines in Fiume in February 1916. Only two of the planned four boats were laid down, but neither were ever launched or completed. The two incomplete submarines were scrapped after the war ended.
