"Implacable" became the deck-landing training carrier for the Home Fleet when she next put to sea in August. On 25 September Captain Aubrey Mansergh assumed command of the ship. Two months later she participated in an exercise with the Home Fleet and was lightly damaged when she collided with the light carrier while docking in Devonport on 7 November. On 1 February 1947, she joined the other ships of the Home Fleet as they rendezvoused with the battleship , which was serving as the royal yacht to escort King George VI as he set out for the first royal tour of South Africa. "Implacable" hosted the king and his family on 7 February, staging a small air show for them after which the queen addressed the crew. After leaving the royals, she made port visits at Freetown, Sierra Leone, and Dakar, Senegal before arriving in the Western Mediterranean for more training. Arriving home on 7 March, she began a lengthy refit at Rosyth on 17 April.
