She was the only ship of her class to retain the original configuration with a straight axial flight deck rather than the angled flight decks of her three sister ships. She was laid down in 1944 in Belfast with the contract being awarded to Harland and Wolff though was not launched until 22 April 1947, sometime after World War II had come to a close, due to delays relating to the end of the war. She was commissioned on 1 September 1953, a gap of almost nine years from when she was laid down in 1944.
