| History | HMS Buttercup was loaned to the Royal Norwegian Navy on 20 December 1944 to replace HNoMS Tunsberg Castle. For the duration of the war Buttercup served on escort duties. Buttercup sailed for Oslo, Norway on 13 May 1945. In 1946 she was purchased outright by the Norwegian government and on 10 August 1946 she was renamed Nordkyn. In November 1957 Nordkyn was sold to the Thor Dahl Whaling Company to be converted into a whaler being renamed Thoris. Thoris was eventually sold for scrapping in June 1969.
