Following the end of World War II, Urchin was placed in reserve. In 1952, she was transferred to the Norwegian Navy and renamed Tromsø. Tromsø served with the Norwegian Navy until 1965 when she was scrapped.

Her wartime service earned Urchin several battle honours, including: Arctic 1944-45 and Normandy 1944.
