The war ended while she was in the dockyard and the Admiralty decided to modify her for use as the Home Fleet's trials and training carrier. In this role she conducted the deck-landing trials for most of the British postwar naval aircraft in the early 1950s. She was occasionally used to ferry troops and aircraft to and from foreign deployments as well as participating in exercises. In 1951, she helped to transport troops to quell rioting in Cyprus after the collapse of the Anglo-Egyptian treaty of 1936. She was paid off in early 1955 and sold for scrap in late 1956.
