Service history edit
Serving with II Flotilla the U-boat carried out seven war patrols and sank four ships for a total of 9,340 gross register tons (GRT), and damaged another of 10,757 GRT tons (HMS Virginian).[2]
About 28 to 30 September 1918 U-102 struck a mine in the North Sea Mine Barrage, east of the Orkney Islands while on her way to home. All of her 42 crew members' lives were claimed by the U-boat's sinking. The wreck of U-102 was located by a sonar sweep in 2006. Information to confirm the identification was obtained by divers in 2007.[2]
