HMAS Adelaide (L01) is the second of two Canberra-class landing helicopter dock (LHD) ships of the Royal Australian Navy. Construction of the ship started at Navantia's Spanish shipyard with steel-cutting in February 2010. The ship was laid down in February 2011, and launched on 4 July 2012. Delivery to Australia for fitting out at BAE Systems Australia's facilities in Victoria was scheduled for 2013, but did not occur until early 2014. Despite construction delays and predictions the ship was commissioned in December 2015.

The Canberra-class design is based on the warship Juan Carlos I, built by Navantia for the Spanish Navy. The contract was awarded to Navantia and Australian company Tenix Defence following a request for tender which ran from February 2004 to June 2007, beating the enlarged Mistral-class design offered by the French company Direction des Constructions Navales. Adelaide has the same physical dimensions as Juan Carlos I, but differs in the design of the island superstructure and the internal layout, in order to meet Australian conditions and requirements. Unlike the Spanish vessel, the Australian ships are built to meet Lloyd's Naval Rules.

The Canberra-class vessels are 230.82 metres (757.3 ft) long overall, with a maximum beam of 32 metres (105 ft), and a maximum draught of 7.08 metres (23.2 ft). At full load, Adelaide will displace 27,500 tonnes (27,100 long tons; 30,300 short tons), making the Canberra-class ships the largest vessels to serve in the RAN. Propulsion is provided by two Navantia Siemens 11-megawatt (15,000 hp) azimuth thrusters, each with an onboard electric motor, driving two 4.5-metre (15 ft) diameter propellers. The electricity is provided by a Combined diesel-electric and gas system, with a single General Electric LM2500 turbine producing 19,160 kilowatts (25,690 hp), supported by two Navantia MAN 16V32/40 diesel generators, each providing 7,448 kilowatts (9,988 hp). Maximum speed is over 20 knots (37 km/h; 23 mph), with a maximum sustainable full-load speed of 19 knots (35 km/h; 22 mph), and an economical cruising speed of 15 knots (28 km/h; 17 mph). Economical range is 9,000 nautical miles (17,000 km; 10,000 mi).

The ship is fitted with a Saab 9LV Mark 4 combat management system. The sensor suite includes a Sea Giraffe 3D surveillance radar, and a Vampir NG infrared search and track system. For self-defence, the LHDs will be fitted with four Rafael Typhoon 25 mm remote weapons systems (one in each corner of the flight deck), six 12.7 mm machine guns, an AN/SLQ-25 Nixie towed torpedo decoy, and a Nulka missile decoy. Defence against aircraft and larger targets is to be provided by escort vessels and air support from the Royal Australian Air Force.

The LHDs will transport 1,046 soldiers and their equipment. Adelaide will be capable deploying a reinforced company of up to 220 soldiers at a time by airlift. Two vehicles decks (one for light vehicles, the other for heavy vehicles and tanks) have areas of 1,880 square metres (20,200 sq ft) and 1,410 square metres (15,200 sq ft) respectively, and between them can accommodate up to 110 vehicles. The well deck will carry up to four LHD Landing Craft, which can be launched and recovered in conditions up to Sea State 4. The flight deck can operate six MRH-90-size helicopters or four Chinook-size helicopters simultaneously, in conditions up to Sea State 5. A mix of MRH-90 transport helicopters and S-70B Seahawk anti-submarine helicopters will be carried: up to eight can be stored in the hangar deck, and the light vehicle deck can be repurposed to fit another ten. The ski-jump ramp of Juan Carlos I has been retained for the RAN ships, although fixed-wing flight operations are not planned for the ships.
