SUBMARINE ""DEUTSCHLAND"" GROUPING The Deutschland was a blockade-running German merchant submarine in action during World War I. She was one of 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 the U-155 armed with six torpedo tubes and a deck gun. During the war she succeeded in sinking 21 vessels before her surrender.
