The U-boat was ordered on 30 April 1915 and launched on 31 December 1915. She was commissioned into the German Imperial Navy on 18 January 1916 as SM UB-29. The UB-29's wreckage - exceptionally well-preserved and with the hull still intact - was found by Belgian divers in the summer of 2017, and formally identified in November 2017. Its exact location was not published, in order to enable further research and protection of the site.
