At the time of purchase, it was decided to incorporate new aircraft carrier technologies into the design, making Melbourne the third [ambiguous] ship to be constructed with an angled flight deck.
The second collision occurred in the early morning of 3 June 1969, when Melbourne also rammed the United States Navy (USN) destroyer USS Frank E. Evans in similar circumstances.
[18] These included an angled flight deck, steam catapult and a mirror landing aid, making Melbourne the third aircraft carrier (following HMS Ark Royal and USS Forrestal) to be constructed with these features, instead of having them added later.
[5] Flight direction radar was included, making Melbourne the only military airfield in the Australasian region at the time capable of operating aircraft at night and in poor weather.
[32] A refit scheduled to begin in late 1981 was postponed in September until a decision regarding the new carrier was made, then cancelled in January 1982, after the announcement that the RAN would be acquiring HMS Invincible.
[19] At Melbourne's commissioning, the standard air group consisted of eight Sea Venoms and two squadrons of eight Gannets, with two Bristol Sycamore search-and-rescue helicopters added shortly after the carrier entered service.
[39] A reduction of embarked plane numbers to four Sea Venoms and six Gannets, along with regular rotation and careful use of the aircraft, extended their service life until the mid-1960s, while the size of the air group was maintained by carrying up to ten Wessex helicopters.
[36][39] The decision to retire the fixed-wing component of the Fleet Air Arm was rescinded in 1963, and on 10 November 1964, a AU£212 million increase in defence spending included the purchase of new aircraft for Melbourne.
[54] Melbourne was unavailable to provide air cover for the RAN for up to four months in every year; this time was required for refits, refuelling, personnel leave, and non-carrier duties, such as the transportation of troops or aircraft.
[61][63] Melbourne sailed east via the Great Australian Bight, meeting sister ship HMAS Sydney near Kangaroo Island a week later.
[61] After visiting Melbourne and Jervis Bay, where the aircraft were offloaded and sent to Naval Air Station HMAS Albatross, the carrier concluded her maiden voyage in Sydney on 10 May.
[65] Melbourne spent from September to November in Southeast Asian waters, during which she participated in Exercise Albatross and received an official visit by Philippines president Ramon Magsaysay.
[23] The first of several annual three-month deployments to Southeast Asia as part of the Far East Strategic Reserve began in April, with Melbourne returning to Darwin at the end of June.
[79] At the beginning of 1963, Melbourne again visited to the Royal Hobart Regatta, which was immediately followed by a deployment to the Strategic Reserve, including involvement in SEATO Exercise Sea Serpent.
[82] The trials involved interactions between both ships, and when Melbourne performed night-flying exercises that evening, Voyager acted as the carrier's plane guard escort.
[93] During this deployment, the carrier visited Subic Bay, where the RAN performed flight deck trials with S-2 Tracker anti-submarine aircraft and A-4 Skyhawk attack fighters.
[114] During Sea Spirit, Melbourne was assigned five escorts: US Ships Everett F. Larson, Frank E. Evans, and James E. Kyes, HMNZS Blackpool, and HMS Cleopatra.
[114] Stevenson held a dinner for the five escort captains at the start of the exercise, during which he recounted the events of the Melbourne–Voyager collision, emphasised the need for caution when operating near the carrier, and provided written instructions on how to avoid such a situation developing again.
[116] In preparation for launching a Tracker, Stevenson ordered Evans to the plane guard station, reminded the destroyer of Melbourne's course, and instructed the carrier's navigational lights to be brought to full brilliance.
[114][119] Seeing the destroyer take no action and on a course to place herself under Melbourne's bow, Stevenson ordered the carrier hard to port, signalling the turn by both radio and siren blasts.
[126] Melbourne departed Singapore on 27 June and arrived in Sydney on 9 July, where the carrier underwent almost identical repairs at Cockatoo Island Dockyard as in 1964 (primarily the installation of a new bow section).
[132] Components were failing due to wear and age, but the companies responsible for manufacturing the parts had gone out of business during the previous twenty years, sometimes immediately after World War II ended.
[126][133] During this year, the carrier also visited Japan to participate in Expo '70, and was hit by Manly ferry South Steyne while alongside at Garden Island, causing minor damage to both vessels.
[134] While the Army supported this proposal, the Navy successfully argued against its implementation, claiming that transporting troops and cargo would be misusing Australia's only active aircraft carrier, and would prevent Melbourne from participating in several major multi-national exercises.
[1] This was followed by goodwill visits to numerous Southeast Asian ports, including Hong Kong, Jakarta, Manila, Singapore, and Surabaya, before Melbourne returned to Sydney at the end of April.
[135] Melbourne, Brisbane, and eleven other ships were deployed as part of the largest peacetime rescue effort ever organised by the RAN: Operation Navy Help Darwin.
[155] The government also announced that the ship would be renamed HMAS Australia and operated as a helicopter carrier, and that a decision on the purchase of fixed wing aircraft would be made after acquisition.
[166] The Australian government received a Telex on this day, reading:[note 4] Please be advised that HMAS Melbourne arrived at Port Huangpu, intact and safely afloat, proud and majestic.
She has been innocent, never once bowed to the natural or human force, in spite of the heavy storm and the talked about jinx.The ship was not scrapped immediately; instead she was studied by Chinese naval architects and engineers as part of the nation's top-secret carrier development program.
[151] A 2012 article in Jane's Navy International stated that the large quantity of equipment recovered from Melbourne "undoubtedly helped" Admiral Liu Huaqing secure the Chinese government's support for his proposal to initiate an aircraft carrier development programme.
