[1] In October 1950 Cardigan Bay was detached for service with the United Nations as part of British and Commonwealth support in Korea, sailing from Hong Kong on 17 November to Sasebo to join the UN Naval Task Group.
She then returned to Sasebo, and began her second Korean tour, patrolling the west coast, supporting the aircraft carrier Glory during coastal bombardments, and preventing movements of enemy shipping.
Large parts of the aircraft were recovered using the LCUs crane and smaller components by divers, while Glory and the cruiser Kenya provided radar and air cover.
On 7 April she embarked American General Maxwell D. Taylor and the Commander of the Commonwealth Naval Forces Admiral Alan Scott-Moncrieff, and sailed to Ch'o-do Island, close to the mouth of the Taedong River to carry out a shore bombardment.
However Cardigan Bay was retained for occasional UN duty on the west coast of Korea into 1955, also taking part in joint exercises with the United States Navy.
In early 1958 she visited New Zealand, calling at Wellington and ports in South Island before resuming service with the Fleet at Singapore and Hong Kong, where she remained until November 1960.
[1] Cardigan Bay then sailed for Australia, calling at Townsville, Queensland, then Nouméa, New Caledonia, Suva, Fiji and Apia, Samoa before refuelling at Pearl Harbor on 9 January 1961.
She then called at Cartagena, Colombia, Maracaibo, Venezuela, Port of Spain, Trinidad and Bermuda before finally arriving back at Plymouth on 7 April to decommission.
