HMS Ocean was a Royal Navy Colossus-class light fleet aircraft carrier constructed by Alexander Stephen & Sons in Glasgow. Laid down in November 1942 and launched in July 1944, she was commissioned on 8 August 1945. The Colossus class was designed for rapid wartime construction, featuring hull standards aligned more with mercantile vessels than traditional naval ships, which resulted in lighter armor and limited anti-aircraft armament. The vessel measured approximately 695 feet overall in length, with a beam of 80 feet and a draught of 23.5 feet. Displacing around 13,190 long tons standard and up to 18,040 tons at deep load, HMS Ocean was powered by four Admiralty 3-drum boilers driving two Parsons geared steam turbines, generating 40,000 shaft horsepower and achieving a top speed of 25 knots. Her operational range was approximately 12,000 nautical miles at 14 knots. The flight deck was 690 feet long and 80 feet wide, supporting a hangar 445 feet long with a clear overhead height of 17.5 feet. Initially designed to carry 24 aircraft, by the time of her operational service, she accommodated up to 37 aircraft, including fighters such as Sea Hurricanes and later Sea Hornets, as well as night fighters like Fireflies. Her armament included six quadruple and seven single 2-pounder pom-poms, along with twelve Bofors 40 mm guns, and a crew complement of around 1,300 officers and ratings. After her commissioning, HMS Ocean underwent modifications at Birkenhead to operate night fighters, including radar upgrades. She conducted trials with aircraft such as the de Havilland Sea Hornet, and notably, on 3 December 1945, she hosted the first carrier landing of a jet-powered aircraft—a Sea Vampire flown by Eric "Winkle" Brown. Her early service included deployment to the Mediterranean Fleet, supporting various operations including troop transport to Singapore, medical aid during the Corfu Channel incident, and participation in the withdrawal from Palestine. HMS Ocean twice served in the Korean War, engaging North Korean MiG-15 jets in combat, and was active during the Suez Crisis, notably executing the first large-scale helicopter-borne assault. She was placed in extended reserve in 1958 and scrapped in 1962 at Faslane. HMS Ocean's service history highlights her role as a versatile and pioneering vessel during the post-WWII era.
