| History | The ships completion was delayed because she was fitted for minesweeping during construction. When completed she was crewed by the Section Belge of the Royal Navy (Free Belgian Navy). 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 1956 or 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. |
