INDEX OF NAVAL
Fleet Aircraft Carrier
Indefatigable was ordered in 1939 and her sister ship in the Implacable Class, HMS Implacable was ordered a year earlier. In response to a Naval Staff requirement for greater speed and increased aircraft complement, an extra turbine and shaft were installed and the lower hangar was extended forward so that it was 46 feet longer than that in Indomitable. The armour plating on the hangar sides was increased to 2", and the height of the lower hangar was lowered by 2 feet so that both hangars had an overhead clearance of only 14 feet. The result was very cramped accommodation spaces, and a restriction on the type of aircraft that could be operated - the hangars were too low for Corsairs, and due to the unavailability of Hellcats the ships were compelled to carry short-range Seafires. The main external differences were the much enlarged funnel and longer island.
Construction was halted in 1940 by order of Winston Churchill, and even after it was resumed little priority was given to their completion. Implacable took 5 years to build, and by the time she was completed Indefatigable her sister was fully operational and already at sea in combat.
After a short period of operations with the Home Fleet, both ships went to the Pacific, where their larger air groups were responsible for the majority of sorties flown by the carriers of the British Pacific Fleet.
The war service of Indefatigable commenced when she was involved in deck-landing trials achieving a 'first' with the first-ever deck landing by a twin engine aircraft, a de Havilland Mosquito. She then joined the Home Fleet in July 1944, to take part in the attacks on the German Battleship Tirpitz in Norway, with Operaytion Mascot of 17 July 1944, then subsequently a further series of attacks on the Tirpitz on 22, 24 and 29 August 1944 as part of Operation Goodwood.

HMS Indefatigable was modified for Pacific service between October-November 1944 and then joined the Eastern Fleet in November 1944. She led air strikes against an oil refinery at Medan with HMS Indomitable and HMS Victorious on 4 January 1945, then in air strikes against Palembang on 24 and 29 January 1945.
Following a period at Sydney in February 1945, she took part in air strikes against Sakishima Gunto and Formosa in March-April 1945. She was the first British ship to be hit by a Kamikaze when serving with the British Pacific Fleet on 1 April 1945. However, however she quickly recovered and became fully operational within 1 hour. She subsequently took part in further strikes against Sakishima Gunto in May 1945. By the end of these operations Indefatigable had contributed one-third of the Fleet Air Arm sorties flown between 26 March and 25 May 1945.
In June 1945 she was at Sydney - machinery breakdown delayed sailing. She then took part in air strikes against Japanese home islands between 24 July-10 August 1945. Indefatigable operated with the American Third Fleet in Japanese waters between 10 August-2 September and her aircraft flew what was officially the last sortie of the war on 15 August 1945, where her seafires shot down 8 enemy aircraft.

Indefatigable was at the Japanese surrender in Tokyo Bay on 3 September 1945, and returned to Sydney on 17 September, after which she repatriated POWs from Japan to Sydney between October-November 1945.
Post war in December 1945 she sailed for New Zealand and return to Sydney, finally departing Sydney at the end of January 1946 for the UK where she arrived on 15 March 1946. She was paid off and put into reserve in December 1946. Post war Indefatigable was recommissioned as a boys training ship in 1950, had her hangars converted to classrooms and accommodation space. Neither ship was significantly modernised, and both were only 10 years old when paid off in August 1954. She was towed to Dalmuir late 1956 for scrapping. Broken up at Troon.

Stricken 1956 and broken up Notes The Implacable Class carriers were a follow-on from the Illustrious class which took Indomitable's modifications a stage further with a full length two-level hangar. Hangar height was even less than in the Illustrious' due to an attempt to stay within the London Naval Treaty's limitations on displacement. By the end of the war, deck parking allowed 81 aircraft to be carried. The lack of hangar height rendered the ships almost useless after the war, unable to operate many modern aircraft.
