The U-boat was ordered on 29 August 1915 and was launched on 4 March 1916. She was commissioned into the German Imperial Navy on 15 August 1916 as SM UC-24. In four patrols UC-24 was credited with sinking 4 ships, either by torpedo or by mines laid. UC-24 was torpedoed and sunk by French submarine Circé off on 24 May 1917. The wreck was found in late 2019 at a depth of 85m, 2 nautical miles from the mainland (Molunat, Dubrovnik, today's Croatia).
