HMAS Melbourne (R21) was a Majestic-class light aircraft carrier operated by the Royal Australian Navy from 1955 to 1982. Constructed by Vickers-Armstrongs at their Naval Construction Yard in Barrow-in-Furness, England, she was laid down in April 1943 and launched in February 1945 as HMS Majestic (R77). Work on her was suspended after WWII, but she was purchased by the RAN in 1947, with significant technological upgrades, including the incorporation of an angled flight deck, steam catapult, and mirror landing aid—making her one of the early carriers equipped for jet aircraft operations. She was commissioned into the RAN in October 1955 and renamed Melbourne shortly thereafter. Her specifications included a standard displacement of approximately 15,740 long tons, increasing to around 20,000 long tons at full load. She measured about 214 meters in length overall, with a beam of 24.38 meters and a draught of 7.62 meters. Propelled by two Parsons turbines powered by four Admiralty 3-drum boilers, Melbourne could reach speeds of up to 24 knots and had an operational range of 12,000 nautical miles at 14 knots. Her complement averaged 1,350 personnel. Melbourne’s armament initially consisted of 25 Bofors 40 mm anti-aircraft guns, with radars including Type 277Q, Type 293Q, and Type 978. Her aviation capacity included a helicopter and fixed-wing aircraft complement, primarily Sea Venom fighters, Gannet anti-submarine aircraft, and later A-4 Skyhawks and S-2 Trackers, reflecting her evolving role in fleet air defense and anti-submarine warfare. Throughout her service, Melbourne participated in numerous deployments, notably in Southeast Asia, the Vietnam War, and various exercises, serving as the fleet flagship. She was involved in two notable peacetime collisions: the sinking of HMAS Voyager in 1964 and a collision with USS Frank E. Evans in 1969, both resulting in significant loss of life and investigations. Despite never firing a shot in combat, her operational history underscored her importance as a symbol of Australian maritime power during the Cold War era. Decommissioned in 1982, she was sold for scrap in 1985, but her legacy endures through memorials and her influence on naval aviation development in China, where she was studied extensively after her sinking.
