| History | HMS Implacable's service history commenced in September 1944 as part of the Home Fleet. She took part in anti-shipping operations off Norway in 26-29 October, and on 27 November 1944.
Following being drydocked to repair weather damage in December 1944, she departed for the British Pacific Fleet on 10 March 1945, where her large air groups, along with those of her sister ship, were responsible for the majority of sorties flown by the carriers of the British Pacific Fleet. She arrived at Sydney in mid-May; and took part in "training strikes" on Truk between 14-15 June 1945, and strikes against Japanese home islands between July-August 1945. She finally returned to the UK from the Pacific on 3 June 1946. HMS Implacable acted as a deck-landing training ship in the Home Fleet between 1946-49, and was again an operational carrier in Home Fleet 1949-52. She became a training ship between January 1952-August 1954 and was paid off on 1 September 1954. Implacable was broken up at Inverkeithing from 3 November 1955. Commanding Officers: Capt. Cecil Charles Hughes-Hallett, RN |
