The Canberra-class vessels are 230.82 metres (757ft 3in)long overall, with a maximum beam of 32 metres (105ft 0in), and a maximum draught of 7.08 metres (23ft 3in).[5] At full load, Canberra will displace27,500 tonnes (27,100 long tons).[5] Propulsion is provided by two Siemens 11-megawatt (15,000hp)azimuth thrusters, each with an onboard electric motor, driving two 4.5-metre (15ft) diameter propellers.[5][6] The electricity is provided by a Combined Diesel-electric and Gas (CODAG) system, with a single General Electric LM2500 gas turbine producing 19,160 kilowatts (25,690hp), supported by two MAN 16V32/40 diesel generators, each providing 7,448 kilowatts (9,988hp).[5] Maximum speed is over 20 knots (37km/h; 23mph), with a maximum sustainable full-load speed of 19 knots (35km/h; 22mph), and an economical cruising speed of 15 knots (28km/h; 17mph).[5] Economical range is 9,000 nautical miles (17,000km; 10,000mi).[5]
Each ship is fitted with a Saab 9LV Mark 4 combat management system.[4] The sensor suite includes a Sea Giraffe 3D surveillance radar, and a Vampir NG infrared search and track system.[4] 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),[7] six 12.7mm machine guns, an AN/SLQ-25 Nixie towed torpedo decoy, and a Nulka missile decoy.[5] Defence against aircraft and larger targets is to be provided by escort vessels and air support from the Royal Australian Air Force (RAAF).[7] The ships' companies will consist of 358 personnel; 293 RAN, 62 Australian Army, and 3 RAAF.[8]
The LHDs will transport 1,046 soldiers and their equipment.[8]Canberra will be capable of deploying a reinforced company of up to 220 soldiers at a time by airlift.[4] Two vehicle decks (one for light vehicles, the other for heavy vehicles and tanks) have areas of 1,880 square metres (20,200sqft) and 1,410 square metres (15,200sqft) respectively, and between them can accommodate up to 110 vehicles.[5] The well deck will carry up to four LHD Landing Craft (LLC), which can be launched and recovered in conditions up to Sea State 4.[5][6] The flight deck can operate six MRH-90-size helicopters or four Chinook-size helicopters simultaneously, in conditions up to Sea State 5.[7] A mix of MRH-90 transport helicopters and Sikorsky 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.[5][9] 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.[8][10]
Construction
Construction of Canberra began in September 2008, when the first steel was cut.[3] The first three of 104 hull 'blocks' were laid down by Navantia at Ferrol in northern Spain on 23 September 2010.[3] The hull was launched on 17 February 2011 by Vicki Coates, the widow of Rear Admiral Nigel Coates, a former commanding officer of the previous HMAS Canberra.[11][12]
The hull of Canberra being floated onto the lift ship MVBlue Marlin, prior to sailing from Spain.
After the completion of the hull up to the level of the flight deck, Canberra was transported to Williamstown, Victoria.[1][4][8]Canberra's hull was floated onto the heavy-lift shipMVBlue Marlin on 4 August 2012, with Blue Marlin departing on 17 August.[13][14] The heavy lift ship sailed via the Cape of Good Hope to avoid the risk of the ship and her cargo being hijacked by Somali pirates.[15] The decision to avoid the shorter route via the Suez Canal and Horn of Africa was made because other options to protect Blue Marlin and Canberra were unworkable: the frigate Anzac could not be diverted from anti-piracy duties in the region to provide a dedicated escort, and Dutch authorities objected to the presence of armed military or security personnel aboard the Dutch-flagged heavy lift ship.[15]Canberra and Blue Marlin arrived in Port Phillip on 17 October.[16] At Williamstown, the installation of Canberra's island superstructure and the internal fitout of the hull was completed by BAE Systems Australia (which acquired Tenix in mid 2008).[1][4][8]
The ship was officially christened on 15 February 2013.[17] BAE continued to build the vessel in Williamstown, Victoria integrating C3 and sensors to the ship's superstructures.[18]Canberra commenced sea trials on 3 March 2014, sailing under power for the first time.[19] The trials program included a visit to Fleet Base East in Sydney for drydocking tests, before returning to Williamstown for communications and weapons testing.[19] The first phase of the trials resulted in vibration damage to decking when the thruster pods were run independently at high speed (instead of in tandem, as designed), and a melted circuit breaker board when primary and emergency power systems were activated simultaneously, along with the discovery of a crack in the hull from the delivery voyage, and excessively corroded propeller nuts.[20] The second phase of contractor-run sea trials began in July, after repairs were made, and had concluded by early September.[20][21]
Canberra was handed over by BAE Systems to the Defence Materiel Organisation on 9 October 2014.[22] The ship was commissioned on 28 November 2014 at Fleet Base East.[23] Although identified as "LHD01" during construction, Canberra received the pennant number "L02" on commissioning; the pennant number corresponding to that used by the frigate of the same name.[24][25]
Operational history

Canberra was the centrepiece of Australia Day celebrations in Sydney on 26 January 2015.[26] In March 2015, the ship was designated the flagship of the RAN.[27]
In February 2016, the ship was deployed from Fleet Base East initially to Brisbane in Queensland where it loaded a Royal Australian Army Engineer squadron and equipment including beach landing capabilities, water purification equipment and other essential engineering stores and then it sailed to Fiji on its first humanitarian mission after a tropical cyclone hit the country on February 20. The LHD was carrying 50 tonnes of humanitarian supplies including food, water, and medical equipment as well as more than 850 personnel from the Australian Defence Force. Embarked with the ship were three MRH-90 helicopters to support Australian operations. The Canberra joined other ADF assets to help with relief efforts.[28]
Canberra formed part of the Australian force which participated in the RIMPAC 2016 exercise off Hawaii during mid-2016. During this deployment she successfully completed flight trials with United States military Sikorsky CH-53E Super Stallion and Bell Boeing V-22 Osprey aircraft.[29]
In May 2017, issues with the vessel's azimuth thrusters were detected. Interim repairs were made.[30]
In August 2020, three missing Micronesian sailors were found alive and well on Pikelot Island in Micronesia. Canberra dispatched a helicopter to provide food and water and check the men for injuries.[31]

HMAS Success was a Durance-class multi-product replenishment oiler that previously served in the Royal Australian Navy (RAN). Built by Cockatoo Docks & Engineering Company in Sydney, Australia, during the 1980s, she is the only ship of the class to be constructed outside France, and the only one to not originally serve in the Marine Nationale. The ship was part of the Australian contribution to the 1991 Gulf War, and was deployed to East Timor in response to incidents in 1999 and 2006. The ship was fitted with a double hull during the first half of 2011, to meet International Maritime Organization standards.
HMAS Choules (L100) is a Bay-class landing ship that served with the Royal Fleet Auxiliary (RFA) from 2006 to 2011, before being purchased by the Royal Australian Navy (RAN). The vessel was built as RFA Largs Bay by Swan Hunter in Wallsend, Tyne and Wear. She was named after Largs Bay in Ayrshire, Scotland, and entered service in November 2006. During her career with the RFA, Largs Bay served as the British ship assigned to patrol the Falkland Islands in 2008, and delivered relief supplies following the 2010 Haiti earthquake.
HMAS Warramunga is an Anzac-class frigate of the Royal Australian Navy (RAN). One of ten frigates built for the Australian and New Zealand navies, Warramunga was laid down by Tenix Defence in 1997 and commissioned in 2001. During her career, the frigate has operated in the Persian Gulf as part of Operation Catalyst, and undertaken anti-piracy operations off Somalia. Warramunga underwent the Anti-Ship Missile Defence (ASMD) upgrade during 2014. She is active as of October 2022.
HMAS Kanimbla was a Kanimbla-class landing platform amphibious ship operated by the Royal Australian Navy (RAN). Originally built for the United States Navy (USN) as the Newport-class tank landing shipUSS Saginaw (LST-1188), the ship was decommissioned in 1994 and sold to the RAN.
The Hobart class is a ship class of three air warfare destroyers (AWDs) built for the Royal Australian Navy (RAN). Planning for ships to replace the Adelaide-class frigates and restore the capability last exhibited by the Perth-class destroyers began by 2000, initially under acquisition project SEA 1400, which was re-designated SEA 4000. Although the designation "Air Warfare Destroyer" is used to describe ships dedicated to the defence of a naval force from aircraft and missile attack, the destroyers are expected to also operate in anti-surface, anti-submarine, and naval gunfire support roles.
Juan Carlos I is a multi-purpose aircraft carrier-landing helicopter dock (LHD) in the Spanish Navy. Similar in role to many aircraft carriers, the amphibious landing ship has a ski jump for STOVL operations, and is equipped with the McDonnell Douglas AV-8B Harrier II attack aircraft. The vessel is named in honour of Juan Carlos I, the former king of Spain.
A joint support ship (JSS) is a multi-role naval vessel capable of launching and supporting joint amphibious and airlift operations. It can also provide command and control, sealift and seabasing, underway replenishment, disaster relief and logistics capabilities for combined land and sea operations.
The Fleet Air Arm (FAA), known formerly as the Australian Navy Aviation Group, is the division of the Royal Australian Navy (RAN) responsible for the operation of aircraft. The FAA was founded in 1947 following the purchase of two aircraft carriers from the Royal Navy. FAA personnel fought in the Korean War and the Vietnam War, and participated in later conflicts and operations from host warships.
The Royal Australian Navy, although a significant force in the Asia-Pacific region, is nonetheless classed as a medium-sized navy. Its fleet is based around two main types of surface combatant, with limited global deployment and air power capability. However, in 2009, a white paper, Defending Australia in the Asia Pacific Century: Force 2030, was produced by the Australian government which set out a programme of defence spending that will see significant improvements to the RAN's fleet and capabilities. In recent times, Australia released its Surface Fleet Review in 2024, which analyses the future of the RAN and shows what the Government will procure.
The Kanimbla class was a class of amphibious transport ships operated by the Royal Australian Navy (RAN). Two ships were purchased by Australia in 1994 and modified. Problems during the handover process and the need to repair previously unidentified defects meant the ships did not enter operational service until the end of the decade.
The Canberra class is a ship class of two landing helicopter dock (LHD) ships built for the Royal Australian Navy (RAN). Planning to upgrade the navy's amphibious fleet began in 2000, based on Australian experiences leading the International Force for East Timor peacekeeping operation. With a new climate for growing Australian Navy spending, a desire existed for forward defence capability for landing and supporting troops on Asian territory, that had never existed in Australian history, even with the old Majestic-class light fleet carriers, HMAS Melbourne and HMAS Sydney in the 1970s. In 2004, French company Direction des Constructions Navales (DCN) and Spanish company Navantia were invited to tender proposals, with DCN offering the Mistral-class amphibious assault ship and Navantia proposing the "Buque de Proyección Estratégica" design. The Spanish design was selected in 2007, with Navantia responsible for construction of the ships from the keel to the flight deck, and BAE Systems Australia handling the fabrication of the combat and communications systems. Finally, Siemens (Germany) supplied and fitted the azimuth thrusters.
A helicopter carrier is a type of aircraft carrier whose primary purpose is to operate helicopters. It has a large flight deck that occupies a substantial part of the deck, which can extend the full length of the ship like HMS Ocean of the Royal Navy (RN), or extend only partway, usually aft, as in the Soviet Navy's Moskva class or in the Chinese Navy's Type 0891A. It often also has a hangar deck for the storage and maintenance of rotorwing aircraft.
HMAS Sirius was a commercial tanker purchased by the Royal Australian Navy and converted into a fleet replenishment vessel to replace HMAS Westralia. She was named in honour of HMS Sirius of the First Fleet. Launched in South Korea on 2004, and converted in Western Australia, Sirius was commissioned in 2006; three years before a purpose-built vessel would have been built, and at half the cost. The tanker was decommissioned in 2021 and subsequently scrapped.
HMAS Tobruk was a Landing Ship Heavy (LSH) of the Royal Australian Navy (RAN), based on the design of the Round Table-class of the British Royal Fleet Auxiliary. Planning for the ship began in the 1970s to provide the Australian Army with a permanent sealift capability. She was laid down by Carrington Slipways in 1979, launched in 1980, and commissioned in 1981. She was a multi-purpose, roll-on/roll-off heavy lift ship capable of transporting soldiers, APCs, and tanks, and delivering them to shore via landing craft or directly by beaching.
The Royal Australian Navy and Australian Army have operated 29 amphibious warfare ships. These ships have been used to transport Army units and supplies during exercises and operational deployments.
HMAS Adelaide (L01) is the second ship of the Canberra-class landing helicopter dock's (LHD). 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 LCM-1E is a class of amphibious mechanized landing craft manufactured by Navantia at their factory in San Fernando. These craft are intended to deliver troops and equipment onshore from amphibious assault ships during amphibious assaults. The craft are operated by the Spanish Navy and the Royal Australian Navy, and have been ordered by the Turkish Navy.
TCG Anadolu (L-400) is a drone-carrying amphibious assault ship of the Turkish Navy. It is named after the peninsula of Anatolia which forms the majority of the land mass of Turkey. The construction works began on 30 April 2016 at the shipyard of Sedef Shipbuilding Inc. in Istanbul, with the keel being laid on 7 February 2018. TCG Anadolu was commissioned with a ceremony on 10 April 2023.
HMAS Sydney, named after the city of Sydney, New South Wales, is the third and final ship of the Hobart-class air warfare destroyers operated by the Royal Australian Navy (RAN).
