SM UB-39 was a German Type UB II submarine that served in the German Imperial Navy during World War I. The submarine was commissioned in 1916 and conducted several successful patrols in the English Channel and North Sea, sinking multiple enemy vessels. In October 1916, UB-39 was damaged in a collision with another German U-boat but managed to return to base for repairs. The submarine continued its operations and sank more ships before being lost in March 1917 due to unknown causes. All 27 crew members aboard UB-39 perished in the incident. The wreck of UB-39 was discovered in 2002 off the coast of Belgium, providing valuable insights into the design and technology of German submarines during the war. The discovery of UB-39's wreck has contributed to the historical understanding of submarine warfare and the challenges faced by German U-boats during World War I.
