U-boats were a significant part of the German Navy's strategy during the war and were used in both the Atlantic and Pacific Oceans. They were responsible for sinking a large number of Allied ships during the war, particularly in the early years of the conflict. The U-boat campaign was a major factor in the Battle of the Atlantic, which was a critical part of the overall war effort.
