Ordered under the 1936 Naval Programme, she was laid down at the Vickers-Armstrong shipyard at Newcastle upon Tyne in 1937 and launched two years later in 1939. Her commissioning was delayed until 1941 due to the greater need for escort vessels for service in the Battle of the Atlantic.
Her service in 1941 and 1942 included famous actions against the battleship Bismarck, several Arctic convoys, and Operation Pedestal. She was loaned to the United States Navy in 1943 and served in the south west Pacific as part of the Third Fleet. In 1944 Victorious contributed to several attacks on the Tirpitz. The elimination of the German naval threat allowed her redeployment first to the Eastern Fleet at Colombo and then to the Pacific for the final actions of the war against Japan.
After the war, her service was broken by periods in reserve and, between 1950 and 1958, the most complete reconstruction of any Royal Navy carrier. This involved the construction of new superstructure above the hangar deck level, a new angled flight deck,[1] new boilers and the fitting of Type 984 radar and data links and heavy shipboard computers, able to track 50 targets and assess their priority for interrogation and interception. The reduction of Britain’s naval commitment in 1967, the end of the Indonesia–Malaysia confrontation, and a fire while under refit, prompted her final withdrawal from service, three to five years early, and she was scrapped in 1969.
