SM U-50

SM U-50 was one of 329 submarines in the Imperial German Navy in World War I. She took part in the First Battle of the Atlantic.

U-50 is most notable for sinking the RMS Laconia (1911), formerly an armed merchant cruiser which had returned to passenger service, killing two Americans before the United States had entered the war. Laconia was also the 15th largest ship destroyed by submarine in the war.
