German submarine Deutschland

Deutschland was a blockade-breaking German merchant submarine used during World War I. It was developed with private funds and operated by the North German Lloyd Line. She was the first of seven U-151-class U-boats built and one of only two used as unarmed cargo submarines.

After making two voyages as an unarmed merchantman, she was taken over by the German Imperial Navy on 19 February 1917 and converted into U-155, armed with six torpedo tubes and two deck guns. As U-155, she began a raiding career in June 1917 that was to last until October 1918, sinking 120,434 GRT of shipping and damaging a further 9,080 GRT of shipping.
