HMAS Adelaide (L01)

HMAS ''Adelaide'' (L01) is the second of two ''Canberra''-class landing helicopter dock (LHD) ships of the Royal Australian Navy (RAN) and is the largest naval vessel ever built for Australia. 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.

Design

The ''Canberra''-class design is based on the warship ''Juan Carlos I'', built by Navantia for the Spanish Navy.Brown, ''Spanish designs are Australia's choice for warship programmes'' 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.Fish, ''First Australian LHD takes shape'' ''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.Fish, ''Amphibious assault ships'' Unlike the Spanish vessel, the Australian ships are built to meet Lloyd's Naval Rules.

The ''Canberra''-class vessels are long overall, with a maximum beam of , and a maximum draught of .Royal Australian Navy, ''Amphibious Assault Ship (LHD)'' At full load, ''Adelaide'' will displace , making the ''Canberra''-class ships the largest vessels to serve in the RAN. Propulsion is provided by two Navantia Siemens azimuth thrusters, each with an onboard electric motor, driving two diameter propellers.''Amphibious Ships'', in ''Semaphore'', p. 2 The electricity is provided by a Combined diesel-electric and gas system, with a single General Electric LM2500 turbine producing , supported by two Navantia MAN 16V32/40 diesel generators, each providing . Maximum speed is over , with a maximum sustainable full-load speed of , and an economical cruising speed of . Economical range is .

Each 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),Defense Industry Daily, ''Australia's Canberra class LHDs'' 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 (RAAF). The ships' companies will consist of 358 personnel; 293 RAN, 62 Australian Army, and 3 RAAF.Kerr, ''Amphibious Ambitions''

The LHDs will transport 1,046 soldiers and their equipment. ''Adelaide'' will be capable of deploying a reinforced company of up to 220 soldiers at a time by airlift. Two vehicle decks (one for light vehicles, the other for heavy vehicles and tanks) have areas of and 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.Borgu, ''Capability of First Resort?'', p. 11

Construction

Construction of ''Adelaide'' began at Navantia's shipyard in Ferrol, northern Spain, during February 2010, when the first steel was cut. Hull modules were fabricated at Ferrol and Fene, with the first hull blocks laid down on 18 February 2011.Fish, ''Australia awaits new LHDs for amphibious uplift'' ''Adelaide''s hull was launched on 4 July 2012. Initially, the ship was due to reach Australia in early 2013 to begin final fitout and superstructure installation at BAE Systems Australia facilities in Victoria, but instead, the hull was loaded onto ''Blue Marlin'' on 10 December 2013 in Vigo Bay. ''Blue Marlin'' and ''Adelaide'' arrived at Williamstown on 7 February 2014. On 17 June 2015, ''Adelaide'' departed from Williamstown to commence sea trials, which included sailing to Sydney for docking at Garden Island, before returning to Williamstown on 11 July. A second set of trials ran from 19 to 28 August, and the ship was delivered to Fleet Base East two days later.

Entry into RAN service was originally planned for mid-2015, but as of July 2011, this had been pushed back to sometime in 2016. Fitting out of the ship progressed at a faster rate than expected, which brought the predicted commissioning date back to September 2015, although this did not eventuate. The ship was formally handed over to the ADF on 22 October, and was commissioned into the RAN on 4 December. Although identified as "LHD02" during construction, ''Adelaide'' received the pennant number "L01" on commissioning; the number corresponding to that used by the frigate of the same name.

Operational history

In early 2016, ''Adelaide'' undertook post-commissioning trials and other activities as the ship was worked up to full operational status.

In September 2016, ''Adelaide'' took part in Exercise Kakadu 2016, based at Darwin, Northern Territory.

On 12 December 2016, ''Adelaide'' intercepted the 50m former Japanese whaling vessel ''Kaiyo Maru No. 8'' in international waters in the Southern Ocean south east of Tasmania. The vessel had attracted the attention of Maritime Border Command after loitering and circling more than 200 nautical miles off the southern coast of Australia. Tactical Assault Group personnel boarded the vessel and located suspected illicit drugs after which the vessel was escorted to Hobart with approximately 186 kilograms of cocaine located on board. The vessel was loitering after a botched rendezvous 300 nautical miles off the coast of Port Fairy in Victoria.

In September 2017, ''Adelaide'' sailed as part of the largest Australian task group to deploy since the early 1980s on Exercise ''Indo-Pacific Endeavour 2017''. This was planned as a series of exercises with nations around the Pacific Rim testing communications, disaster relief plans and regional security. ''Adelaide'' was accompanied by fleet oiler and a varying number of escorts, with a total of four frigates (, , and ) sailing from Sydney on 4 September 2017. The last time such a large deployment of Australian warships went to sea was September 1980, led by the aircraft carrier .

On 5 January 2020, ''Adelaide'' sailed as part of Operation Bushfire Assist, assisting with the Royal Australian Navy's ongoing efforts to help evacuate people from bushfire zones that have become cut off by road and air due to conditions.

On 18 January 2022, ''Adelaide'' departed from Sydney for Brisbane on its way to provide disaster relief to Tonga following the Hunga Tonga–Hunga Ha'apai eruption and tsunami. On 25 January, the Department of Defence confirmed that 23 crew members aboard the ''Adelaide'' had tested positive for COVID-19 while enroute to Tonga. On 26 January, the ''Adelaide'' docked in Tonga to make a contactless delivery to avoid COVID-19 transmissions. During its period at Tonga the ship was crippled for several days when its main and backup power systems failed. It was reported that as a result of the power failure, most of the crew were forced to sleep "above deck". On 17 February, navy officials revealed the first power outage on 29 January was likely due to volcanic debris in seawater blocking the cooling systems of the ship's diesel generators, which eventually led to multiple system failures. The second outage on 30 January was a fault on the gas turbine.

In September 2022, ''Adelaide'' participated in Exercise Trident, a joint amphibious landing exercise with the Singapore Armed Forces at the Shoalwater Bay Training Area. More than 1,600 personnel from both nations were involved, as well as two Republic of Singapore Navy landing platform docks ( RSS ''Endurance'' and RSS ''Persistence''), Chinook and Apache helicopters, and LHD Landing Craft (LLC).
