She was completed on 10 June 1915 and was commissioned by the Royal Navy the same year. However, her service in the Royal Navy was short. On 19 January 1916, she ran aground near the Dutch island of Schiermonnikoog, after which she was interned by the Royal Netherlands Navy. On 4 May 1917, an agreement was reached to sell H6 to the Netherlands.
The Royal Netherlands Navy renamed H6 to HNLMS O 8 and refitted her, with knowledge gained from the interned German submarine UC-8. After UC-8 was bought from Germany O 8 was equipped with UC-8'sZeiss periscope. During maintenance in October 1921, O 8 partly sank in the harbour at Den Helder.[2] Because only minor damage was sustained, she was repaired and continued in service. In the summer of 1925, O 8 together with the other Dutch vessels HNLMS K XI, HNLMS Jacob van Heemskerck, HNLMS Marten Harpertszoon Tromp, HNLMS Z 3 and HNLMS Z 5 were part of an exercise in the Baltic Sea.
During the German attack on the Netherlands at the start of the Second World War, O 8 was still in Dutch service. At the time she was undergoing maintenance and as a result could not escape during the invasion.[9] Instead it was decided to scuttle her.[10]
After the surrender of the Netherlands, the German forces were able raise O 8 and found her almost fully intact.[11]
Germany took O 8 into service as UD-1 and transferred her from Den Helder to Kiel. In Kiel, she was used as training ship to train crews for the German U-boats. Because of her age, she was decommissioned on 23 November 1943. On 3 May 1945, she was scuttled again in the harbour at Kiel.[12]
