21 June 1926, O 11, together with the O 9, Maarten Harpertszoon Tromp, Jacob van Heemskerck, Z 7 and Z 8, sailed from Den Helder to the Baltic Sea to visit the port of Kiel, Göteborg and Trondheim.[2]

In 1927 O 11, O 10, Hertog Hendrik, Z 5, Z 6, Z 7 and Z 8 made a visit to Norway.[2]

She sails for the Baltics again in 1936 with her sisters O 9, O 10 and Hertog Hendrik and Z 5. In 1939 O 11 together with her sisters O 9, O 10 where attached to the coastal division. They acted as the offensive part of the Dutch coastal defense.[2]

6 March 1940 the ship was accidentally rammed by the tugboat BV 3 in Den Helder. In the collision three man of the O 11 died. The boat was raised and its repair was ordered. While under repair Germany invades the Netherlands and the boat was scuttled to prevent her capture. The Germans raised the boat and ordered its repair. However it is not repaired in time to help in the war effort.[2]

While still under repair the boat is scuttled again in order to block the entrance of the Den Helder harbor. On 10 December 1947 the wreck was raised and sold for scraping.[2]
